Title: Improvements in and relating to digital computing apparatus
Inventor: LORCH HUGH OLAF
IPC: G06F7/38
Filed: 1958-08-08
Abstract: 932,621. Circuits employing bi-stable magnetic elements. ENGLISH ELECTRIC CO. Ltd. Aug. 7, 1959 [Aug. 8, 1958], No. 25488/58. Class 40 (9). [Also in Group XIX] A saturable core with a main winding A in series with a non-linear resistor R, a condenser C2 and a source S of alternating current (20 kc/s.) operates in either of two stable states. The circuit gives a direct current output from feedback winding B which is returned to the lower terminal of the supply S. The polarity of the output indicates the state of operation. If the core is unbiased, there is no direct current output. If the core is initially biased by one of the windings C, D, E, the flux change in the core takes up a greater proportion of the applied voltage in one half-cycle than it does in the other. The resultant direct current output on feedback coil B maintains the bias when the original bias is removed and the circuit remains in a stable operating state. The device may be used as a logical element with three inputs applied to the windings C, D, E. Adder. Two stages of a circuit for adding two ten digit numbers is shown in Fig. 3. In each stage, the AND and EXCLUSIVE OR elements 10, 11 first add the two corresponding digits A and B of the stage, the outputs of 10, 11 signalling respectively a carry digit and the sum. The digits 1 and 0 are represented by +1 unit and - 1 unit of flux bias. Elements 12, 13 add the sum from 11 and the carry digit signalled from the previous stage on C1 or C2. A carry digit arising from the addition performed by 12, 13 is signalled to the next stage over C2.

Title: Improvements in or relating to polishing and buffing machines
IPC: B24B57/00
Filed: 1958-08-08
Abstract: 836,751. Polishing. CLAIR MFG. CO. Inc. Dec. 31, 1958 [Aug. 8, 1958], No. 25627/58. Class 60. A machine for polishing, buffiing, burnishing or the like of the kind having a polishing roll 14, Fig. 1, on which abrasive or polishing material is distributed by one or more traversing compressed-air spray guns 25 is provided with means where-by the air supply to the guns is cut off at the end of each pass to avoid spraying during reversal of the sprayer carriage. A valve unit 30, Fig. 6, for controlling the air supply to the guns 25 comprises a piston 80 having a tubular, apertured, portion 82, forming a slide valve which in its uppermost position, under the influence of an adjustable spring 88, shuts off the air supply and vents to atmosphere the pressure in the air lines 28 to the guns, but when under air pressure from above, the piston 80 is moved to a position in which the air supply to the guns is reestablished via ports 100 and 106 and lines 52 and 28. The control valve unit 30 and the guns 25, with their common air supply pipe 26 and polishing-preparation feed lines 110, 111, are mounted on a carriage reciprocable in a guideway 34, arranged above the polishing roll 14, by a piston 46, Fig. 3, working in a cylinder 40 to which air is admitted alternately to and exhausted from opposite sides of the piston by a solenoid-controlled valve 55 having an inlet 59 and outlets 60. A passage 72 through the piston rod 48 admits air via a pipe 75 to the space 78 above the gun control valve piston 80 to bring it into the operative position during the travel of the sprayer carriage. A block 70 contacts a switch 68 at the end of the traverse, reversing the valve 55, thus shutting off the air pressure on the right-hand side of the piston and to the space over the piston 80, allowing the spring 88 to move the piston to its sprayer cut-off position. If the guns are required to operate at each pass pressure above the piston 80 may be reestablished during the return of the piston 46 by throttling the exhaust outlets 60 by adjusting screws 61 to cause a back pressure within the cylinder sufficient to move the piston 80 to re-open the air supply to the guns during movement of the carriage. An abutment arm 115 contacts a pressure-relief valve 114 to vent the space above the piston 80 as the carriage reaches the end of its travel to the right thereby again cutting off the air supply to the guns. The switch 68 is again operated by a stop-block to throw over the solenoid-controlled air-valve 55 to reverse the travel of the sprayer carriage and the cycle is repeated. In the embodiment of Fig. 1, the machine is used for polishing spoons and forks and has two rotating rolls 14, 14A, to provide a polishing gap for the workpieces ; the latter may be fed individually or ganged on a frame 18 which may be arranged to reciprocate longitudinally of the polishing rolls and also towards and away from the polishing gap, as described in U.S.A. Specification 2,458,708.

Title: Piston rings
IPC: F16J9/20
Filed: 1920-09-06
Abstract: 163,947. Gill, M. S. Sept. 6, 1920. Piston packing.-The low-pressure edge of a packing-ring for the piston of an internalcombustion or steam engine, compressor, or pump, is formed with a pressure - relieving groove 17, Fig. 6, which terminates short of the split in the ring and communicates with the periphery by grooves 25. The ring is pressed by the fluid pressure, and, in order to reduce friction, the radial pressure of the packing may be balanced partially by fluid pressure admitted to a peripheral groove 20, Figs. 4 and 6, by axial grooves 24. A mumber of grooves 25 may be employed, or these may be replaced by two broad and shallow grooves, diametrically arranged, and each at 90‹ from the split in the ring. The ring has over-lapping ends 12, 13, the end 13 having also a tongue which enters a recess 15 in the end 12. In a modification a radial butt joint is employed with which the groove 20 communicates, the grooves 24 being dispensed with. In the case of a double-acting piston, two packing-rings are employed, which are alternately effective, the edges containing the grooves 17 being arranged to face in opposite directions. The packing rings may be arranged in separate grooves, or in a single wide groove. In place of two rings, a single double-acting ring may be employed, Fig. 12. This ring has a pressure-relieving groove V, V<1> io each edge, and two peripheral grooves 40, 41, communicating with the slit in the ring.

Filed: 1937-09-22
Abstract: 485,634. Permutation locks. HUTSON, T. W. Sept. 22, 1937, No. 25688. [Class 44] In a keyless lock having permutation discs arranged concentrically round the handle shaft, a spider plate 2, turned by the handle shaft 9, has projections which enter inclined notches on the permutation discs 1, the inclination of the notches forcing the spider plate out of the plane of the discs against the action of a spider spring 7 so that the handle can be turned to retract the bolt. The under sides of the discs are also notched to guard against picking, the projections entering these notches when the combination is incorrect and butting against raised portions of an inner wall of the casing to relieve the discs of pressure. The discs are returned to zero by quadrants 3 rotating pinions 4 on the disc spindles 16, the quadrants being engaged by pins on a plate 5 turned by the handle shaft 9 through a lost motion joint or directly by a thumbscrew 8 in the centre of the handle shaft. The lock may be put out of action from inside the door by a plate having an arm extending through the lock casing, cams (i on the plate passing behind the spider plate 2 and pushing it out of the plane of the discs 1. To change the combination, the discs 1 are lifted off the splined ends of the spindles 16, on which they are retained by springs, and replaced in fresh positions.

Abstract: 1340906 Electron microscope SIEMENS AG 19 April 1971 [28 March 1970] 25688/71 Heading H1D An electron probe microanalyser comprises means for detecting electrons back scattered from a point of incidence of the probe electron beam 1, e.g. through polepiece 2 upon a specimen 3, which may be scanned, thereby providing a signal dependent on both the topographical and chemical nature of the specimen, the signal supplying one input to signal superposition circuitry 8 which receives also as second input a specimen current signal dependent on the chemical nature at the point of incidence, the superposition circuitry producing an out put information signal which is dependent on the topographical nature and less dependent on the chemical nature. Representations of the surface may be light and dark areas on an image tube 11, via intensity modulation input, or on a magnetic tape recorder 12. Signals may be digital or analogue depending on the nature of specimen current electrode and electron detector and the superposed signals may be added or subtracted depending on the polarity of the output signals in relation to earth. For analogue signals, the superposition unit may be an addition or difference amplifier while for digital apparatus a superposition may, at equidistant intervals of time, subtract the quantity in a first counting device for the specimen current signal from the quantity in a second counting device for the back scattered electron detector, and release it to a recording device. In the Figure, detector 6 containing an amplifier is connected to polarity inverter 7, and electrode 9 to amplifier 10. Deflection in tube 11 may be controlled by the scanning arrangement for beam 1. Line and raster scanning microanalysers are mentioned.

Abstract: Each duct (1, 2) consists of a flexible plastic tube which has identical end rings (4, 7) at its two ends. The end rings (4, 7), fitted into each other, of the adjacent ducts (1, 2) form a first coupling which absorbs axial forces. The second coupling consists of a sleeve (8) which surrounds the first coupling consisting of end rings (4, 7) from the outside. Each sleeve (8) is split into two halves (9, 10). A fastening (24) serves to join together the facing edges (19, 20) of the halves (9, 10). The fastening (24), which advantageously consists of lacing cord, is pulled through recesses (21, 22) in each sleeve half (9, 10). Separation of the ducts (1, 2) from one another is avoided by the second coupling even at maximum pressures. In addition, the sealing capacity of the tube connection in the couplings is improved. <IMAGE>
