Abstract: A refrigeration control system for modulating an electrically-operated expansion valve in which a modulating, electrically-operated expansion valve is connected to the evaporator inlet, and first and second condition-responsive electrical sensors are positioned to respond to conditions at selected location in the system. An electrical amplifier circuit connects the condition-responsive electrical sensors to the valve for regulating the opening and closing of the valve in response to differences in the conditions sensed by the sensors. Refrigerant is fed to at least one of the sensors so as to cause modulation of the expansion valve. More particularly, the condition-responsive sensors are temperature-responsive, the first sensor being positioned to respond to the temperature of the liquid refrigerant expanded to suction pressure, and the second sensor being positioned to respond to suction line sensible temperature.

The hook and loop fastener includes a hook portion and a loop portion, one of the hook and loop portions being fixed to the tongue and the other of the hook and loop portions being fixed at one of the upper portions of the vamp, and the hook and loop portions engaging to hold the tongue to the one upper portion of the vamp. The tongue includes a fixed lower end and a free upper end. The hook and loop fastener is located near the free upper end of the tongue.

Abstract: This portable battery booster assembly includes a booster battery having positive and negative electrical connections. A portable housing contains the booster battery. A negative booster clamp is electrically connected to the battery booster negative connection, and a positive battery booster clamp is electrically connected to the battery booster positive connection. A pair of electrically conductive terminals are carried by the portable housing with each terminal selectively receiving one of the booster clamps for providing an electrical connection between the terminal and the battery. The housing includes a handle with an insulated bar carried by the handle. The bar carries a pair of tubular sleeves which provide the conductive terminals. Insulators electrically isolate the two sleeves from each other and from the handle.

Abstract: A pilot-operated pressured regulator valve includes a main valve for controlling refrigerant flow in a refrigeration suction line. A pilot valve which is responsive to evaporator pressure controls a flow of high pressure refrigerant to the main valve for modulating the main valve. A bleed is provided for bleeding the high pressure refrigerant from the main valve. A solenoid-actuated shut-off valve controls the bleed flow from the main valve. The shut-off valve is selectively closed for maintaining the high pressure refrigerant in the main valve for closing the main valve. A bleed flow of high pressure is provided to the main valve when the shut-off valve is closed in order to maintain the main valve closed.

Abstract: A tilting table includes a table top attached to an upper U-shaped bracket. A lower U-shaped bracket is rotatively attached by a bearing to a base. The lower U-shaped bracket includes a pair of opposed side, substantially horizontal slots and a pair of opposed side angle slots. The angle slots include a plurality of notches. Pins are slidably received in the slots, and are carried by the upper bracket for supporting the table top. The pins are selectively positioned in the notches of the angle slots, while the pins slidably move in the substantially horizontal slots for selectively inclining the table top.

Abstract: This fuel pre-heat device includes a tubular section, which is connected at each end to a radiator hose to receive heat from the hose, and a fuel line section which is wrapped around the holder. A housing is provided to enclose the wrapped fuel line, and a pressure regulator is connected to the fuel line to regulate the pressure of fuel entering the engine.

Abstract: This compact gear box is intended for a corn harvesting unit having a pair of harvesting rolls and a pair of gathering chain assemblies. The gear box includes a drive shaft and first and second pairs of shafts connected to the harvesting rolls and the gathering chain assemblies respectively. The drive shaft includes a bevel gear driving a bevel pinion gear mounted to the end of each of the first pair of shafts to rotate the harvesting rolls. The first shafts each include worm gears and the second shafts each include worm wheels engageable by associated worm gears of the first pair of shafts to rotate the gathering chain assemblies.

Abstract: This fastening device provides a self-contained, tie-down unit by means of which load from a swivel eye is transferred to a base. The fastening device includes a stud, threadedly connectible to a base and mounting a collar and a retainer member. The retainer member supports a bushing member, and the bushing member and collar provide a swivel mount for the load ring. The bushing member and stud cooperate to transfer variable loadings into the base in a manner predictable from their size and configuration.
