Abstract: A trailer includes a tongue which may be pivoted from a center position to either side by operation of one of the brakes on the ground support wheels. A L-shaped loading fork is provided at the forward end pivotal from a position where the forwardly extending legs of the fork move under the bale to a position where they extend upwardly and the other legs extend rearwardly along the trailer frame. A pair of conveyors are provided along the length of the frame for moving the hay from one end to the other and for unloading the hay. An unloading apparatus is provided at the rear end which includes oppositely disposed upstanding posts having vertically pivotal arms to which are connected horizontally disposed stub shafts for engaging the bale at its axial center. The bale is rotated by engagement with a conveyor on its lower side thereby unrolling it as it is rotated.

Abstract: A moving coil electrical meter mechanism has a substantially rectangular coil and a magnetic structure surrounding first, second and third sides of the coil and defining first, second and third magnetic flux filled air gaps containing magnetic fields so oriented that the forces exerted on the first, second and third sides of the coil are in the same direction. The rectangular coil is mounted to rotate under the influence of the magnetic fields around an axis adjacent to the fourth side of the coil, with the magnetic fields remaining orthogonal to the coil sides during rotation.

Abstract: A vehicle has an axle assembly which comprises an axle, which axle includes a steering knuckle pivotally mounted to a rigid axle housing, and a spindle, for supporting a wheel of the vehicle for rotation, mounted to the steering knuckle. The steering knuckle and spindle have mounting pads which are held in facing relationship. In its apparatus aspects, the present invention involves a tapered shim member interposed between the mounting pads in order to adjust the angle formed by the spindle and axle to thereby adjust the camber of the wheel. In its method aspects, the invention involves changing the angle between the spindle and axle. The present invention finds an important application in adjusting the camber of the front wheels of conventionally constructed four-wheel drive vehicles.

Abstract: A system for the disassembly, warehousing and inventory of used vehicle parts obtained from used vehicles has conveyor means on which a used vehicle is transported during disassembly, means for removed used parts from the used vehicle while it is being transported on the conveyor, and a storage area for storing the used parts removing during disassembly. The system further has means for identifying the used vehicle parts stored in the storage area and means for maintaining inventory records of the used vehicle parts which are stored in the storage area. A method for providing used vehicle parts obtained from used vehicles compromises the steps of conveying a used vehicle along a conveyor line, sequentially removing selected used parts from the vehicle, identifying used vehicle parts, storing used vehicle parts in a storage area and entering and maintaining inventory information on the used vehicle parts in a record-keeping system.

Abstract: A new and improved sissy bar for a motorcycle which has a movable portion so that a single rider on the motorcycle can use it as a conventional sissy bar or can position it immediately behind him for use as a backrest. If the rider has a passenger, he can position it for the comfort of the passenger. Preferably the slidable portion of the sissy bar is slidably mounted on a support bar which is attached to the frame of the motorcycle. When used as a backrest, it is slidably positioned relative to the seat to the position that the operator desires, and locked into place. A variation also permits the operator to adjust the tilt for maximum comfort. The device is simply constructed and easy to operate with a minimum of moving parts.

Abstract: A mechanism for moving a tape through a printing apparatus in which said mechanism includes a back-space shuttle mounted to a frame for reciprocal movement and an advancing shuttle mounted to the back-space shuttle for reciprocal movement. Movement of the advancing shuttle in its operative direction by an advancing actuation arm of the printing apparatus causes the tape to be gripped by the advancing shuttle and advanced. The tape slips through the back-space shuttle during movement of the advancing shuttle in its operative direction. Movement of the back-space shuttle in its operative direction by a back space actuation slide of the printing apparatus causes the tape to be gripped by the back-space shuttle and back-spaced. The tape slips through the advancing shuttle during movement of the back-space shuttle in its operative direction.

Abstract: The present invention concerns a toy telephone or home intercom in which the electrical parts and connections are prefabricated into a self-contained unit which can be detachably mounted in a telephone case.

Abstract: A method of molding finger rings of the type having a hollowed-out interior portion, but whose exterior surfaces are identical to rings without such hollowed-out portion comprising securing a wax, shell ring pattern to the exterior surface of a wax, tubular section to form a wax ring pattern and molding a finger ring from said wax ring pattern via an investment method of casting.

Abstract: A method for oxidizing odorous constituents of contaminated gas with minimum consumption of the oxidizing agent. Apparatus is disclosed for causing contact between the contaminated gas and the scrubbing liquid by means of opposed flow through a porous bed of packing material. The method is primarily useful in controlling odorous emissions from rendering plants, fish processing plants, asphalt plants, and other plants in which aldehydes, fatty acids, ketones, mercaptans, amines, hydrogen sulfide, sulphur dioxide, nitric oxide, phenols or other pollutants are emitted. Chlorine in the form of sodium hypochlorite in a concentration of 5-50 ppm is the preferred oxidizing agent. Consumption of the oxidizing agent is minimized by continuously purging 1-5% of the scrubbing liquid to thereby promptly remove precipitates and other solids.

Abstract: A large scale liquid cooling assembly has two stages for air cooling of hot liquid. Each stage has a plurality of liquid spray units for selective controlled projection of liquid drops in at least one trajectory extending generally perpendicular from its unit and in a common horizontal direction therefrom. The drop sizes, velocities and volume rates of the liquid spraying are adapted to provide a directional wind effect across the unit along the common horizontal direction. The water can be initially cooled in the first stage, and subsequently further cooled in the second stage. At least some of the units of the second stage are adjacent some of the units of the first stage, and create directional wind effects complementary to the directional wind effect of the first stage.The alignment of the liquid spray units in the two stages can take several different forms.

Abstract: An improved, reuseable golf tee comprising a shank element and a head element connected with each other for relative limited pivotal movement. The head element includes a ball supporting portion threadedly connected with a shank retaining portion such that tightening of the threaded connection restricts the freedom of such pivotal movement between the head and shank elements.

Abstract: An improved pressure control valve and unloader valve incorporating a floating check valve which is responsive to a gradual restriction in the discharge line and is also responsive to the shock wave formed as a result of a sudden shut-off of the discharge line; and the combination of such a pressure control valve with a high pressure diaphragm pump.
