Title: Improvements in or relating to intelligence storage equipment
Inventor: RIDLER DESMOND SYDNEY
IPC: G11C11/22
Filed: 1956-04-06
Abstract: 813,580. Circuits employing bi-stable magnetic or dielectric elements. STANDARD TELEPHONES & CABLES Ltd. April 5, 1957 [April 6, 1956], No. 10651/56. Class 40(9). In a storage matrix in which column wires are used for reading and writing purposes a readout pulse induced in a column wire by a storage element is applied to a first transistor causing it to conduct and trigger a bi-stable circuit into a stage in which it conditions a second transistor to pass a half-write pulse to the column wire to restore the initial state of the element. In Fig. 2 a 4 x 4 matrix is composed of ferrite blocks 5, 6, 7, 8 each drilled with four holes 51, 52, 53, 54, the spacing between which may be 3 mm. if, to avoid bulk magnetization, row wires such as 511 are threaded through adjacent holes in alternate directions. Column wires 9, 10, 11, 12 are earthed at opposite ends. Toroids 1, 2, 3, 4 form an access selector, each toroid having an output winding to drive a row wire, and a bias winding energized in series with the bias windings of the other toroids by a battery B; this bias circuit being given a high impedance by inductance L and being regulated by a resistor R1. Coincident pulses, each producing a flux in a pair of toroids equal to their bias, when coincident on the same core, such as pulses PI, P2, on core 1, switch the core and provide a read-out pulse in the associated row winding. The pulses P1, P2 are generated by pentodes which are allowed to bottom and therefore produce voltage-limited pulses from a low-impedance source. The duration of the pulses is just sufficien t to switch the toroid and when they have ceased the toroid is switched back to its initial state by the bias to produce a half-write pulse applied to the row winding. If a digit is read out of hole 51 in block 5 the consequent pulse induced in the column wire fires a transistor T1 to trigger a bi-stable circuit CC into a stable state in which an output is applied to the base of transistor T2 which conducts and opens a path for a half-write pulse applied over transformer TX, diode D2 and resistor R7; this pulse being coincident with the half-write pulse produced by toroid 1 in the access selector as it returns to biased saturation. The digit is rewritten in the hole 51 and subsequently a reset-pulse is applied to bi-stable circuit CC. Each block has an additional hole such as 5X which always registers 0 and when read out produces a " sneak " pulse which is applied to the emitter of transistor T1 to cancel " sneak " pulses induced in the column wire. Specifications 760,048 and 781,331 are referred to.

Title: Apparatus for the automatic injection or supplying, through the induction system of internal combustion engines, to the combustion chamber, liquids other than the fuel supplied by the carburetter, such as the injection of water and particularly of oil for the purpose of lubricating the cylinder walls, pistons and valves
IPC: F02M25/022
Filed: 1927-04-25
Abstract: 290,428. Hibbert, H. April 25. 1927. Lubricant conveyed by fluid.-Oil or water is drawn into the induction system of an internalcombustion engine by the suction prevailing therein from a tank A through a depending tube C, past a piston valve F, through a passage E, an adjustable sight-feed device D, and a pipe H. The valve F, which is provided with flats or the like so as to permit the passage of the liquid, is pressed towards a seating M by an adjustable spring G, so that, when the engine is stopped, the valve moves on to its seating and prevents siphoning. During the operation of the engine the valve is raised from its seating by the suction action and, if the suction increases, progressively closes the passage E, thus maintaining an approximately constant flow. Specifications 15597/12, 210,898, [Class 135, Valves &c.], and 224,301, are referred to.

Abstract: 1468970 Charge coupled devices PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 12 March 1974 [19 March 1973] 10970/74 Heading H1K [Also in Division H3] In a charge coupled device, the voltage dependent property of the capacitances is utilized to compensate for signal degradation along the device. Fig. 3 shows a device using a four-phase clock in which bias sources 13, 14 are included in the switching signal circuits to vary the values of the depletion capacitances between a maximum value when they contain information charges or a minimum value when they contain reference charges. Instead of the depletion capacitances, the inversion capacitances may be utilized, Figs. 7, 8 (not shown), this latter arrangement being further modified by splitting the electrodes into two parts (62, 63). In a further modification, Fig. 12 (not shown), the electrode of a capacitor the source electrode of the next transistor are not one continuous surface region. The arrangement of Fig. 3 may also be modified to use 2-phase clock signals, Fig. 13 (not shown). Instead of FET's, bipolar transistors may be used, employing either PN or Schottky barrier capacitances. Bipolar constructions are described with reference to Figs. 10, 11 (not shown), the latter employing lateral transistors.

Abstract: 719,492. Injectors. MASCHINENFABRIK AUGSBURG-NURNBERG AKT.-GES. May 1, 1952 [May 8, 1951], No. 10982/52. Class 71. The inlet c for liquid laden with solid particles and discharged through a tube e by a working liquid jet nozzle b is periodically scavenged by return flow of liquid from the nozzle b and tube e on closing a movable member e.g. a flap valve g in the tube e. The valve g is actuated by a piston h which normally is held in the valve opening position by a spring and hydrostatic pressure in a throttled tube k, and on partial blocking of the particle-laden liquid inlet c the resulting pressure drop in tube k causes the piston h to fall and close the valve g. Cam-like projections f form a strainer at the inlet c, the cross-sectional area of which is reduced to below that of the tube e.

Title: Improvements in or relating to apparatus for automatically controlling the width of webs passing therethrough
IPC: G01B13/04
Filed: 1956-04-11
Abstract: 796,526. Stretching webs transversely. FIRESTONE TIRE & RUBBER CO. April 11, 1956 [Aug. 3, 1955], No. 11006/56. Class 100(1) An apparatus for controlling the width of a web comprises an arcuate surface engaging one face of the web, a guide detecting each edge of the web and movable in response to changes in width of the web, and means responsive to the movement of the guide to change the arc of the surface as a result of changes in web width. As shown, a bowed covered roller 5, around which the web, not shown, passes, comprises bearings 7c rotatable on an axle 7. The axle 7 consists of sections 7a and 7b secured together by a bearing 6 to permit relative twisting of the sections. The sections 7a, 7b comprise individual sections connected by the bearings 7c to permit arcuate adjustment of the roller 5. The outer ends ot the axle sections 7a, 7b are each secured to an upper arm 9 of a bellcrank lever 9, 11 which is rocked about a stud 10 by a piston rod 48 pivoted therto. The piston rod 48 has a piston, not shown, enclosed by a ring 47 and cover plate 50. The piston is urged downwardly by a spring 52. Variations in air pressure transmitted through pipes 42 from one of two air valves 4a, 4b positioned adjacent each selvedge, causes the piston rod 48 to rock the bell-crank levers 9, 11, about the stud 10, thereby twisting the axle sections relatively to one another. In operation, fingers 31 are positioned laterally to correspond to the required width of the web by adjustment of blocks 20 along slots 21 in a channel-shaped member 23. The blocks 20 are connected by a chain, not shown, passing around sprockets, not shown, which may be rotated to adjust the distance apart of the blocks by rotation of handwheels 17. The web assumes a width corresponding to the curvature of the roller 5; any increase in the width determined by the positions of the fingers 31 causes one of these fingers to be rocked against the action of a spring 38 connected to a pivotally mounted yoke 27 attached to one of the fingers 31. A valve 34 is thereby lifted from its seat 35 to bleed air through the pipe 42 from a supply pipe 56, thus causing lowering of the piston and rocking of the bell-crank lever 9, 11 to vary the curvature of one section 7a of the roller axle and so vary the web width. The piston may alternatively be actuated hydraulically by providing a recirculation of liquid bled through the valve 34.

Abstract: 1,077,339. Data processors. INTERNATIONAL BUSINESS MACHINES CORPORATION. March 14, 1966 [April 5, 1965], No. 11013/66. Heading G4A. A control device for a data processor having a plurality of channels includes a delay device adapted to produce a plurality of sequential control signals in response to a request signal on one of said channels, and one or more of the control signals initiates a response on the respective one of said channels. A channel requiring service sets a corresponding service latch (11) to control a priority circuit (14-17) which selects the lowest-numbered channel requiring service and sets a buffer trigger (21). The latter applies a signal to a multi-tapped delay circuit (3) and prevents further service latches (11) being set. The outputs from the delay circuit (3) send two signals to the selected channel at times depending on the channel, latches (43, 53) being provided to prolong some such signals. An AND circuit (33) responds to outputs of the delay circuit (3) to reset the service latches (11) and the buffer trigger (21) thereby allowing further service requests.
