Villu Movie Review

Villu - Loose strings

The hype and hoopla surrounding Villu, prior to its release was huge. Director Prabhudeva and actor Vijay promised lots of entertainment. Unfortunately the end product is far from impressive as it is a ‘chaotic’ cocktail of comedy, action and needless stunt sequences far from any logic.

Prabhudeva is greatly impressed by Abbas – Mastan’s Bollywood hit Soldier. But in trying to remake the movie, he has far-stretched his imagination, which fails to find its way with audience’s favour.

It’s a wholesome Vijay show. The actor is at his best – be it the stunt sequence, comedy or romantic episodes. There is an aura of style in whatever he ventures to do on screen. He is as usual cool in his mannerisms. Prabhudeva portrays him an invincible one-man army who floats on water and fly on air with ease and élan. But his hard labour is foiled by wafer-thin storyline, which has no logic.

The story is as old as that of lithic age – an angry son who taking revenge on those responsible for the death of his father. Vijay enacts a dual role – that of a son and father. Prabhudeva has laced it with commercial elements including comedy and action.

The movie revolves around a macho-man Pughazh (Vijay). Thanks to the help of Joseph (Manoj K Jayan), a honest cop, Pughazh begins his search for a international gangster and arms supplier JD (Prakashraj). Meanwhile, Pughazh goes to a village to attend a wedding and comes across Jhanvi (Nayantara). After cat and mouse games, love blossoms between them. Pughazh comes to know that she is the daughter of JD. He sets to Munich in Germany to meet JD along with Jhanvi. He meets JD’s gang (Sriman, Anandhraj and Devaraj). After initial encounters, he evolves his own plans and starts eliminating them one after another.

A flashback reveals why Pughazh is behind their blood. His father ‘Major’ Saravanan (Vijay) gets killed by a gang, which is led by JD, when he prevents them from selling arms to ultras. JD and his team enact a drama and bumps off Saravanan before managing to create an impression that he was the one who had nexus with ultras and succeeds in branding him an anti-national. Eventually Pughazh manages to bring JD to India and avenge them for their wrong-deeds and establish his father’s innocence

Vijay walks away with all honours, while Nayanthara catches the imagination of the audience appearing in skimpy costumes appearing in peppy numbers with Vijay. Vadivelu tries his hand at evoking comedy and succeeds fairly especially the scenes involving Vijay, Nayantara and himself.

Prakashraj platys a clichéd don who controls international arms racket. His dialogues and acts are far too predictable. The rest of the cast including Geetha, Ranjitha, Devaraj, Anandhraj play their part on screen.

Devi Sri Prasad has come up with some peppy numbers while Raviverman’s cinematography is passable. Thanks to Fefsi Vijayan’s stunts Vijay has belied law of gravitation. The real scene-stealer is however the producers Ayangaran Internationals, who have come out with a grand venture. Almost every frame is rich and lavish.

On the whole, Vijay’s Villu is a action-packed mass masala film for his ardent fans but with loose ends

PNEUMATIC FOUR-AXIS MATERIAL HANDLING EQUIPMENT

SYNOPSIS

The technology of pneumatics has gained tremendous importance in the field of workplace rationalization and automation from old-fashioned timber works and coal mines to modern machine shops and space robots. Certain characteristics of compressed air have made this medium quite suitable for used in modern manufacturing and production industries. It is therefore important that technicians and engineers should have a good knowledge of pneumatic system, air operated valves and accessories.

A pneumatic system consists of a compressor plant, pipe lines, control valves, drive members and related auxiliary appliances. The air is compressed in an air compressor and from the compressor plant the flow medium is transmitted to the pneumatic cylinder through a well laid pipe line system. To maintain optimum efficiency of pneumatic system, it is of vital importance that pressure drop between generation and consumption of compressed air is kept very low. Pneumatic material handling system is used to move the components from one place to another with a maximum weight of 3.5 kg. It is used in the following places:

• Chemical laboratories
• Welding
• Foundry, etc.

INTRODUCTION

Material handling is a specialized activity for a modern manufacturing concern. It has been estimated that about 60-70% of the cost production is spent in material handling activities.

Need for material handling:

· Reduction of lab our and material cost

· Reduction of overall cost

· Increased production

· Increased storage capacity

· Increased safety

· Reduction in fatigue

· Improved personnel comfort

WORKING PRINCIPLE

The experimental setup consist of four cylinders, all are of double acting type. The cylinder1 is used to actuate rack and pinion assembly, piston rod of cylinder 1is connected to rack, which is meshed with the pinion. By operating the cylinder1, rack and pinion turns the whole assembly for 260°. By varying the length of the rack the turning angle can be altered. Vertical cylinder or cylinder2 is used to increase the height of the setup. The height is limited to piston rod length. Horizontal cylinder or cylinder3 is used to increase the arm length, the working area of the arm is limited to length of the piston rod length. Gripper cylinder or cylinder4 is used to actuate the gripper.

APPLICATIONS

• Discharge of work piece

The arm feed has a wide application in low cost automation industries. It can be used in automated assembly lines to pick up the finished product from workstation and place them in bins. it can also be used to pick raw material and place them on the conveyor belts.

• Work clamping

This unit can also be used in clamping. Operation in certain areas of mass production where clamping and an clamping have to be done at high speeds. The application of these units is limited to operations which involved moderate clamping forces.

§ Tool Changing Application

When the pneumatic arms are made smaller in size they can be used in automatic tool changes in CNC turning and drilling machines, by attaching tool holding device to the rotary cylinder

ADVANTAGES

The pneumatic arm is more efficient in the technical field

• Quick response is achieved
• Simple in construction
• Easy to maintain and repair
• Cost of the unit is less when compared to other robotics
• No fire hazard problem due to over loading
• Comparatively the operation cost is less
• The operation of arm is faster because the medium used to operate is air
• Continuous operation is possible without stopping

LIMITATIONS

• While working, the compressed air produces noise therefore a silencer may be used.
• High torque can not be obtained
• Load carrying capacity of this unit is not very high.(<50N)

AUTOMATIC ELECTRO-HYDRAULIC JACK FOR FOUR WHEELER

SYNOPSIS

This project work titled “AUTOMATIC ELECTRO-HYDRAULIC JACK FOR LIGHT VEHICLE” has been conceived having studied the difficulty in lifting the any type of light vehicles.

Our survey in the regard in several automobile garages, revealed the facts that mostly some difficult methods were adopted in lifting the vehicles for reconditioning.

Now the project has mainly concentrated on this difficulty, and hence a suitable electronic control unit has been designed. Such that the vehicles can be lifted from the floor land without application of any impact force. By pressing the button in the dashboard, the electronic control unit activates the hydraulic jack automatically.

The fabrication part of it has been considered with almost case for its simplicity and economy, such that this can be accommodated as one of the essential tools on automobile garages.

INTRODUCTION

This device the automatic electro-hydraulic jack for light vehicle garages has been developed to later the needs of small and medium automobile garages.

In most of the garages the vehicles are lifted by using screw jack. This needs high man power and skilled labors.

In order to avoid all such disadvantages, this automatic electro-hydraulic Jack has been designed in such a way that it can be used to lift the vehicle very smoothly without any impact force. The operation is made be simple that even any person can handled, by just pressing the button

WORKING OPERATION

The dash pad switch was activated at the time of any breakdown condition. The control signal is given to the solenoid valve, when the button is activated. The same time, the motor is started which is coupled with rotary hydraulic pump. The oil is suctioned from the oil tank and compressed oil goes to the solenoid valve.

The solenoid valve is activated at the time of dash pad button “ON”. The compressed fluid (oil) goes to the hydraulic cylinder. The compressed oil pusses the hydraulic cylinder piston and move forward. The RAM is fixed at the end of the single acting hydraulic cylinder. The piston moves towards the ground and the ram is lifting the vehicle upwards.

The solenoid valve is deactivated at the time of dash pad button “OFF”. The hydraulic cylinder fluid (oil) goes to the solenoid valve. Then the oil returns back to the oil tank, by the time of deactivating the solenoid valve. Thus the extra oil not required to maintain the oil level in the oil tank.

ADVANTAGES

Ø It requires simple maintenance cares

Ø The moving parts of this system are cooled by the oil itself used. Thus this project does not require any cooling arrangements.

Ø The loaded light vehicles can be easily.

Ø Checking and cleaning are easy, because of the main parts are screwed.

Ø Handling is easy.

Ø Manual power not required

Ø Repairing is easy.

Ø Replacement of parts is easy.

Ø Maximum height up to 1.5 feet can be reached.

Ø No Oil wastage.

DISADVANTAGES

1. Initial cost is high.

2. High maintenance cost.

APPLICATIONS

Ø It is very much useful for Car Owners & Auto-garages. This automatic electro-hydraulic jack is used for lifting the vehicles.

Ø Thus it can be useful for the following types of vehicles;

1) MARUTI,

2) AMBASSADOR,

3) FIAT,

4) MAHINDRA,

5) TATA
