Patent number: 4705082Abstract: A pump (18) draws liquefied carbon-dioxide from a reservoir (4 or 6) and delivers it via a controllable heater (20) and a filling valve (14) to a cylinder (26) to be filled to any required density. This receiver cylinder (26) is controllably warmed by a heater (32) while sensors (22,24) are provided to indicate the pressure and temperature of its contents.For each required density a table of figures is provided relating pressures (above saturation pressure) to temperature, for that density.A temperature (which must be clear above the lowest temperature at which the receiver will be liquid-fill at the required density but which need not exceed the critical temperature) is selected, and the heaters (20 and 32) are controlled so that the receiver cylinder and its contents will converge at or near that temperature as filling is completed.During the final phase of filling the indicated temperature will rise slowly and the pressure (from the time the receiver is liquid-full) will rise relatively fast.Type: GrantFiled: June 26, 1985Date of Patent: November 10, 1987Inventors: Hew D.

Patent number: 4651792Abstract: A tire pressurizing system is provided for automatically pressurizing a pneumatic tire. The system employs centrifugal force to actuate a pump which is attached to the interior of the tire. Centrifugal force causes a pump actuating member to follow a different orbital path around a rotating tire from the path of the pump housing, which is attached to the tire. The difference is due to the flexing of the tire in the load bearing "footprint" area. The result is reciprocation of the actuating member, which in turn operates a pump. Piston and diaphragm pump embodiments are disclosed. An automatic pressure regulator is also provided.Type: GrantFiled: July 2, 1984Date of Patent: March 24, 1987Assignee: Allen F.

Simultaneously with each successive withdrawal of the needle from the valve housing, slide members reciprocated in fixed support base operable to present air sealing device in path of reciprocatable plunger, to urge the sealing device into valve housing aperture for retaining air in the inflated ball. With each withdrawal of inflating needle from fully inflated ball and after insertion of sealing device, full distention of inflated ball actuates ball sizing means to release inflated ball and initiate next successive ball inflation cycle.Type: GrantFiled: April 19, 1973Date of Patent: January 20, 1976Inventor: Lloyd H.
