A plumbing hookup kit for making water supply connections between any of numerous different fittings such as faucet shanks, toilet tank fill valve shanks, and valve, coupling and adapter compression and slip fittings in 3/8", 7/16" and 1/2" sizes. The kit includes a length of supply tubing with an annular terminal attached to each end, together with a seal ring adapted to encircle each terminal. With smaller fitting sizes, the seal ring and terminal effect a fluid tight connection in cooperation...

A coupling apparatus for allowing one person to releasably connect a first object to a second object, which second object has a first engageable portion, a second engageable portion and a third engageable portion, is disclosed. The coupling apparatus includes a first connector mechanism associated with the first object for releasably engaging the first engageable portion of the second object. The coupling apparatus further includes a second connector mechanism associated with the first object fo...

A plumbing hookup kit includes a length of flexible tubing having terminals mounted on each end; different sized brass compression nuts; a brass ferrule; a pair of identical plastic sealing sleeves of one size and a pair of identical plastic sealing sleeves of another size; four identical split locking ring components, pairs of which are adapted to be combined into a locking ring; a pair of identical sealing rings of one size and another larger sealing ring. Different components of the plumbing ...

In the delivery of bulk gasoline to an underground storage tank assurance that the vapor recovery hose is properly connected is provided by sensing of an excess vacuum in the delivery truck tank. Such vacuum occurs when air and/or gasoline vapor is not permitted to replace the gasoline drained from the truck tank. To prevent air from entering the truck tank when the vapor hose is not properly connected to both the truck tank and the storage tank (1) a complete dry break coupling is employed at t...

A battery hookup assembly is provided for transmitting current from an auxiliary power source to a battery of a motor vehicle. The battery hookup assembly includes a housing adapted to be fixedly mounted to a portion of the motor vehicle. First and second terminals are fixedly secured to the housing for selectively receiving current from the auxiliary power source. At least one cable extends between the first and second terminals and the battery for transmitting current received by the first and...

An agricultural implement has a forwardly extending tongue connectible to the drawbar of a towing tractor and includes a fore and aft drive shaft that is disposed above the tongue and adapted to be connected to the PTO output shaft of the tractor by a PTO hookup assembly that includes front and rear universal joints respectively connectible to the implement drive shaft. When the hookup assembly is not connected to the tractor, the front end of the assembly is supported on the implement by a supp...

This invention provides an apparatus for automatically connecting a gas supply to a vessel employed to contain molten metal whereby gas, such as argon, is injected into the molten metal in a selected interior portion of the vessel, such as a ladle. The ladle is positioned on a tilting structure so that it can be tipped to flow out slag on the top on the molten metal, the slag and other impurities in the metal being directed to the top thereof by the upwardly flowing argon gas. The apparatus comp...

A compressor driven by a three phase electric motor is contained within a housing that is filled with refrigerant and is hermetically sealed with a terminal board. The terminal board has three electrical feedthrough terminals for coupling three of the motor's six winding leads to a three phase power source. An insulator having a fourth terminal is disposed inside the housing and is attached to one of the feedthrough terminals. In a high voltage application, such as 4160 volts, the fourth termina...

A small solder tip, which advantageously allows for the rapid production of reliable solder joints without the addition of extra solder, flux or striping the insulation on the wire. The solder tip is preferably formed of tungsten carbide and is used in conjunction with a reflow power supply. In a specific application, the solder tip is utilized for hook-up of magnetic head wires to solder pads. The solder tip comprises a center shaft which allows expanding gases to escape in order to prevent sol...

An auxiliary switch hookup assembly in a motor contactor includes a slide member biased by a spring and forming a portion of the limiting wall for the reception of an auxiliary switch. The spring force exerted by the biasing spring can be greater than a total force exerted by restoring and contact compression springs of the motor contactor.
