Filed: 1969-08-14
Abstract: 1281072 Valves; change-speed control ALLIS-CHALMERS MFG CO 14 Aug 1969 [16 Aug 1968] 40686/69 Headings F2D and F2V] Movement of a spool valve 1 to opposite sides of closed centre acts to connect one of the work posts 60, 61 to a chamber 24 which is connected to a pressure supply pump via a regulator (26) and a pressure reducing valve 47. The pressure in chamber 24 will drop on connection to cause the pressure fluid in accumulator chamber 41 to drain to reservoir 56 past spring-loaded discharge valve 44 which moves to the right. The bias on reducing valve 47 will thus be reduced as the piston 31 moves to the left. After the rapid discharge of accumulator pressure valve 44 moves back to closed position and the pressure slowly builds up in chamber 41 again as the fluid passes from chamber 24 through restriction 43. The bias on the reducing valve 47 will thus slowly increase to increase the pressure in chamber 24 and the working pressure. Spool 1 is locked in actuated position by spring-loaded plungers (15), (17) and has grooves 111, 112 for gradual connection of the chamber 24 with the work parts. In use the ports 60, 61 are connected to the cylinders 70, 75 of a shuttle clutch 64 so that according to which cylinder is pressurized a driven shaft 82 is connected to a drive shaft 80 through one of the disc stacks 96, 89. The drive is accordingly via gears 105, 102, 100, 99, collar 94 disc stack 96 and housings 73, 67 or collar 84, disc stack 89 and housing 67 to give a change in speed range for shaft 82. The valve may also provide fluid for a torque converter, a power take-off valve, or a clutch lubricating and cooling unit.

Abstract: 1394377 Cathode-ray storage tubes TEKTRONIX Inc 12 Sept 1972 [14 Sept 1971] 42277/72 Heading H1D In a storage tube permitting a high writing speed, the transmission storage target 14 is formed by a mesh provided with a thick dielectric layer 12 i.e. greater than 5 microns, and preferably 10 to 30 microns, thick, and of a density less than 10% of the bulk density, such that when subjected to low energy flood electrons from flood guns 42 while having a preparation pulse in the range 10 to 40 volts applied thereto, with the electric field adjacent the rear surface of the target maintained less than, and preferably less than 10% of, the voltage gradient across the dielectric 12, the sides of the dielectric adjacent the mesh apertures continue to charge negatively after the front surface has reached the flood gun cathode voltage, to drive the dielectric to cut-off before the termination of the pulse. The dielectric is preferably of porous, low density magnesium oxide, aluminium oxide, potassium chloride, or magnesium fluoride, and the low electric field therebehind is produced by the shielding action of a second storage target 18, having a thinner dielectric layer and therefore longer storage time, interposed between the first target and the high voltage phosphor display screen 20. In operation, target 10 is held at about 150 volts, to permit the flood electrons to pass uniformly therethrough, while a 300 volt pulse is applied to target 18 to erase any previous image, whereafter it is held at a working potential of 150 volts while the preparation pulse is applied to the target 14, and a positive charge image is written thereon by the writing gun 30. A transfer pulse of about 800 volts is thereafter applied to the target 18 so that flood electrons transmitted through the image on target 14 form a second image on target 18. Finally, a viewing pulse of about 150 volts is applied to the target 14 to permit the flood electrons to pass uniformly therethrough, and to produce a light image on the phosphor screen 20. Reference is made to the possibility of writing the image directly upon target 18 by holding targets 14 and 18 both at 150 volts; to operation in a half-tone storage mode merely by holding the target 18 at the same potential as the display screen 20; to a variable persistence half-tone storage mode in which a train of positive pulses is applied to the target 14 after the writing of the image; to the substitution of a mesh electrode (70, Fig. 3, not shown) for the target 18; to the omission of target 18, with provision for switching the potential of the phosphor screen between values appropriate to preparation and writing on the one hand, and to viewing on the other (Fig. 4, not shown); to the production of the high velocity writing electrons by a photocathode in a television camera storage tube; and to the production of an electrical readout signal by scanning of the charge image.
