Title: Blue color ac gas discharge display panel and method
Inventor: SAHNI OMESH
IPC: H01J17/20
Filed: 1976-12-23
Granted: 1979-11-06
Abstract: BLUE COLOR AC GAS DISCHARGE DISPLAY PANEL AND METHOD     Abstract A blue color AC gas discharge display panel is obtained by the room-temperature Hg vapor seeding of high pressure Ar gas as the luminous gas mixture.  Typically, the panel uses room-temperature Hg (approximately 3m Torr) in several hundred Torr of argon.  Generally, good resolution is achieved in standard AC panels in at least 300 Torr.  The upper limit is nominally one atmosphere.  This gives an Hg seeding of less than 0.001% of the total gas pressure.          Thus, direct electron excitation of Hg atoms is negligible and the discharge condition involves only the excitation of argon atoms by the electrons.

Abstract: BE IT KNOWN THAT GORDON B. FRENCH of Route 8, Box 253, Bakersfield, California, U.S.A., having made an invention entitled:     MULTIPLE LEVEL PREPARATION OF OIL SHALE RETORT     the following disclosure contains a correct and full description of the invention and of the best mode known to the inventor of taking advantage of the same.     Abstract of the Disclosure A subterranean deposit containing oil shale is prepared for in situ retorting by initially excavating a plurality of vertically spaced apart voids of similar horizontal cross section located one above another within the deposit.    A zone of unfragmented deposit temporarily left between each adjacent pair of voids has a thickness greater than the smallest lateral dimension of the voids above and below it.   Explosive placed in a lower portion of the unfragmented zone is detonated to expand the lower portion of the unfragmented zone into the lower void, leaving the upper portion of the zone intact and creating a space free of fragmented particles below it.   Thereafter, the remaining portion of the unfragmented zone is explosively expanded into the open space below it and into the upper void, forming a subterranean room filled with a fragmented mass of particles having a void volume substantially equal to the total initial volume of the voids.   Retorting of the expanded mass is then carried out to recover shale oil from the oil shale.   1.

Abstract: PILOT ACTUATED DIAPHRAGM VALVE          Abstract of the Disclosure A diaphragm valve operated by a solenoid pilot for opening and closing the gasoline passage from a pumped inlet to the nozzle of a gasoline dispenser.  A valve body forms an internal fluid passage for series installation with that of the dispenser.          An annular seat surrounds the body passage at an intermediate location while an upstream facing diaphragm cooperates with the seat to open and close the passage to fluid flow.  A spaced apart valve plate in combination with the diaphragm form a liquid tight chamber into which gasoline at the inlet can enter through restrictive one-way orifices.  Fluid pressure in the chamber aided by a bias spring urges the diaphragm toward the seat in opposition to pump pressure at the inlet.    The pilot valve is spring biased toward a closed relation and is loop connected from the chamber to the outlet.  Energi-zing the pilot effects a reduction in chamber pressure enab-ling relatively greater inlet forces against the diaphragm to move the diaphragm toward open position.  The pilot valve also operates as a backflow restrictor from the dispenser hose and in response to an overpressure opens to permit backflow to the chamber.  A relief valve located internally of the chamber operates in conjuction with pilot backflow operation to re-lieve chamber pressure buildup to the inlet.   la

Abstract: ABSTRACT OF THE DISCLOSURE An apparatus for feeding record cards to and from a utilization station in a record card utilization machine comprises a support housing for a card origination hopper and a card collection hopper, which is mounted below the origination hopper.  A transfer carriage is mounted for reciprocal, pivoted movement from a first position where it receives a card from the origination hopper, to a second position at the utilization station where the card is utilized, and back to the same first position where it returns the card to the collection hopper.  A card feeding and returning mechanism is associated with the hoppers to feed cards to and remove cards from the carriage at different times in the sequence of operation of the apparatus, but nevertheless with the carriage at the same first position in its path of reciprocal, pivoted travel.  An operation aligning a card received on the carriage in the utilization station, performed by coaction of the card with an alignment platform, also sets up the card for receipt by the feeding and returning mechanism for return to the collection hopper.  A transverse car-riage and card aligning operation is performed by interaction of a cam, mounted at the utilization station, and a cam follower, mounted on the car-riage, when the carriage is pivoted to its second position.
