Weeding is one of the major control operations in the vegetable crops. The traditional method of weed control is to remove the weed manually by a Khurpi or Spade. This is a very time consuming process. Due to shortage of agricultural labour in peak season, farmers cannot compete weeding in time. Mechanical weeding keeps the soil surface loose, which results in better aeration and moisture conservation. In our country the average land is about 0.

Manual harvesting of paddy is more time consuming and has become a costly operation. Hence there is a need for mechanization of harvesting, at present the available machinery for harvesting are large in size and expensive and are not reaching the small scale farmers. The rotary type cutting mechanism has been developed with the proper transmission system by using the knapsack power sprayer engine as a prime source.

Field experiment was conducted at Agronomy farm of Dr. B.S. Konkan Krishi Vidyapeeth, Dapoli during kharif season of 2014 to study the effect of different weed management practices on yield, quality and nutrient uptake of kharif rice (Oryza sativa L.). The experiment was laid out in a randomized block design. There were ten treatments which were replicated thrice.

The undulating and sloppy geography, small size fields with uneven topography, lack of skilled labour, poor repair and maintenance facilities, low purchasing capacity of farming community and non-availability of improved farm implements and machines are some of the main reasons for low level of mechanization in the hilly region of the state. By keeping in mind the problems faced by the farmers in hilly areas and to promote farm mechanization a new type of rotary plough cum weeder is designed.

Investigating microbial metabolic characteristics and soil organic carbon (SOC) within aggregates and their relationships under conservation tillage may be useful in revealing the mechanism of SOC sequestration in conservation tillage systems. Crop residue retention has been considered a practicable strategy to improve soil organic carbon (SOC) but the effectiveness of residue retention might be different under varied tillage practices.

An ideal veneer surface is crucial for good panel properties in plywood manufacturing. The aim of this study was to compare plasma treatments and sanding (mechanical) processes with respect to the surface roughness of veneers. Rotary-cut veneers with a thickness of 2 mm from Scots pine (Pinus sylvestris) logs were used as material.

The objective of study was to evaluate some of the physical and mechanical properties of medium density fiberboard (MDF) panels laminated with veneer sheets compressed at different levels of pressure and temperature. Rotary peeled veneer samples of European beech (Fagus orientalis Lipsky) were compressed at temperatures of 150 C, 180 C, and 200 C using 4 MPa and 6 MPa pressure for 8 min. Commercially produced MDF samples also were laminated with such compressed veneer sheets.

The invention of the wheel revolutionized activities as disparate as transportation, war, and the production of pottery (for which it may have been first used). It did not take long to discover that wheeled wagons could be used to carry heavy loads and fast (rotary) potters' wheels enabled early mass production of pottery. But it was the use of the wheel as a transformer of energy (through water wheels, windmills, and even treadmills) that revolutionized the application of nonhuman power sources....

W.M. Berg manufactures several styles of gears. Each gear has and serves its own particular application. Listed below are brief descriptions and application notes for the variety of available styles. Further information can be obtained from numerous gear and mechanical design handbooks, or by contacting our engineering department Gear Types Spur Gears are the most recognized style of gear. Spur Gears are used exclusively to transmit rotary motion between parallel shafts, while maintaining uniform speed and torque.

Most students of electricity begin their study with what is known as direct current (DC), which is electricity °owing in a constant direction, and/or possessing a voltage with constant polarity. DC is the kind of electricity made by a battery (with de¯nite positive and negative terminals), or the kind of charge generated by rubbing certain types of materials against each other. As useful and as easy to understand as DC is, it is not the only \kind" of electricity in use.

An engine (Fig. 11-1) is a machine that converts heat energy into mechanical energy. The heat from burning a fuel produces power which moves the vehicle.Sometimes the engine is called the power plant. Automotive engines are internal-combustion(IC) engines because the fuel that runs them is burned internally, or inside the engine. There are two types: reciprocating and rotary (Fig. 11-2). Reciprocating means moving up and down, or back and forth. Most automotive engines are reciprocating. They have piston that move up and down, or reciprocate, in cylinder (Fig.11-3).

CHAPTER 11 PNEUMATIC AND HYDRAULIC MACHINE AND MECHANISM CONTROL DESIGNS AND OPERATING PRINCIPLES OF TYPICAL PUMPS These pumps are used to transfer liquids and supply hydraulic power. 1. WITH BUT TWO MOVING PARTS, the rotors that turn in the same direction, this rotary pump has reduced friction to a minimum. The rotors rotate against flexible synthetic rubber cushions that allow sand, grit and other abrasives to flow freely through the pump without damage. It is a positive displacement pump that develops a constant pressure and will deliver a uniform flow at any given speed.

This cartridge-operated rotary actuator quickly retracts the webbing to separate a pilot forcibly from his seat as the seat is ejected in emergencies. It eliminates the tendency of both pilot and seat to tumble together after ejection, preventing the opening of the chute. Gas pressure from the ejection device fires the cartridge in the actuator to force the ball-bearing screw to move axially. The linear motion of the screw is translated into the rotary motion of a ball nut. This motion rapidly rolls up the webbing (stretching it as shown) so that the pilot is snapped out of his seat.
