Title: Error detection
IPC: G06F11/10
Filed: 1964-03-19
Abstract: 1,057,162. Computer error-detecting arrangements. WESTERN ELECTRIC CO. Inc. March 19, 1964 [March 29, 1963], No. 11610/64. Heading G4A. In an error-detecting arrangement, signals of different classes, e.g. signals representing data and signals representing instructions, are provided with distinctive parity bits. Thus, data and instructions can be distinguished when read from the memory of a computer. If an incorrect parity is found, the memory can be re-addressed. As shown, an instruction is read from a memory M to an instruction register IR and its parity, which should be even, is checked in a checker IPC. If the parity is incorrect, an indicator IEI is operated and the memory address is prevented from being incremented by an inhibitory signal applied to a gate ICG so that the same instruction can be obtained again from the memory during the next cycle, and normal sequencing is resumed if there is correct parity. A parity checker DPC checks the parity, which should be odd, of data words and if an incorrect parity is detected actuates an indicator DEI and inhibits the address incrementing circuit IC.

Abstract: 456,724. Exhaust silencers. VOKES, C. G., 95, Lower Richmond Road, Putney, London. May 16, 1935, No. 11734. [Class 7 (ii)] A silencing-device comprises two or more silencers designed to produce different resulting noises, and means whereby the gases may be caused to take alternative paths, each of which includes passage through one or more of the silencers. The Figure shows two silencers 1, 2 connected to a common inlet 14 fitted with a valve 17 adjustable to cut out either silencer, the valve being preferably spring-pressed into the one or the other position ; or the valve may be adjusted so that the gases pass through both silencers. The silencer 1 comprises a series of Venturi tubes 6 with curved baffles 7, 8 at each end which cause an ejector action upon the gases entering the space surrounding the Venturi tubes. The silencer 2, which is intended to produce less back-pressure but greater silence, is composed of conical chambers 11, some of which may have deflector plates 12 giving a whirling action. The valve 17 could be replaced by interconnected butterfly valves in the two branches 15, 16.

Filed: 1955-04-27
Abstract: 768,634. Gas filters. HERSEY, H. J. April 27, 1955 [May 7, 1954], No. 12131/55. Class 8(2) The duration and volume of a reverse jet of filter cleaning air under positive pressure are respectively automatically controlled by a relay device responsive to the pressure difference between both sides of an inward flow filter sleeve 20 Fig. 1 and serving to start and stop a motor 80 driving a, blower 72 feeding a revolving nozzle 50. and by a device for controlling the speed of the blower motor 80 and which is also responsive to said pressure differences. The cleansing nozzle 50 is rotated between the sleeve 20 and a supporting frame 30 by a hollow shaft 40 geared to a motor 66 and having supply arms 52, 54. Starting of motors 64, 80 is effected when a pivoted lever 120 Fig. 3 of a pressure switch box 102 is swung to the left by expansion of a bellows 114 connected by a duct 110 to the high pressure side of the sleeve 20 to contact a point 124 whereupon a double-pole singlethrow normally open relay 128 is energized by a source of e.m.f. applied to lines 134, 136 thereby closing contacts 140, 142 in lines 132, 134 leading to a starter box 94 for said motors 64, 80. A locking switch 164 maintains the relay energized even though contact between point 124 and lever 120 may be broken. Stopping of the motors 64, 80 is effected when the lever 120 is swung to the right by expansion of a bellows 116 connected by a duct 106 to the low pressure side of the sleeve 20 to contact a point 126 whereupon a singlepole single-throw normally closed relay 130 is energized by the e.m.f. across lines 134, 136 and thus breaks a normally closed switch 156, 158 in line 134. The speed of the blower motor 80 is controlled by a lever 174 connected by links 176, 192 and a bell crank 180 to the free end of a bellows 186 connected by a duct 202 to the high pressure side of the sleeve 20 whereby as the cleaning thereof proceeds and the back pressure diminishes the volume of cleaning air is gradually reduced. In a modification the blower motor runs at constant speed and the bellows 230 Fig. 4 (not shown) controls an air bleed valve in the blower outlet. Specification 682,217 is referred to.
