Title: Improvements in apparatus for use in electric or electronic digital computing machines
Inventor: BOOTH ANDREW DONALD
IPC: G11C19/04
Filed: 1950-08-14
Abstract: 761,121. Pattern-movement stepping registers. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Aug. 10, 1951 [Aug. 14, 1950], No. 20154/50. Class 106 (1). [Also in Group XXXIX] A shifting register for an electric digital computer, e.g. for use in multiplication and division, comprises magnetic storage devices, each comprising a core of magnetic material, whose B/H characteristic exhibits a remanent value closely approaching its saturation value, having separate input and output windings thereon, the storage devices being arranged in cascade with the output winding of one connected to the input winding of the next by way of a unidirectionally conductive and gate circuit means. As shown, each storage device comprises a toroidal core T with input, output and shift windings A, B, C. A pulse, representing " 1," on input winding A will change the magnetization of the core from negative to positive Br, Fig. 2, i.e. from the zero to the " 1 " condition. When a zeroizing shift pulse is applied to windings C, if a core is in the " 1 " condition, the change in magnetization from Br (positive) to B sat (negative) will produce a large output pulse in winding B which is sent through a delay device DL1, DL2 ... and a rectifier and gate IR1, IR2 ... normally open but closed by the shift pulses, to the winding A to enter " 1 " in the next storage device. Each delay device may comprise an inductance having continuously distributed capacitance by being wound on a conductive former. The rectifier and gate may be separate, or their functions may be combined in a single magnetic device, similar to the storage devices or developments thereof, as described in Specification 761,131, [Group XXXIX]. In another form of shifting register (Fig. 4, not shown), digits are shifted from one storage device to the next by way of auxiliary storage devices controlled by a further staggered series of shift pulses, and the gates are normally blocked and opened only by the shift pulses, the delays being omitted.

Patent GB-478652-A (GB)
Title: Improvements in or relating to automatic switch controlling circuits for automatic telephone or like signalling systems
IPC: H04Q3/00
Filed: 1936-07-21
Abstract: 478,652. Automatic exchange systems. AUTOMATIC ELECTRIC CO., Ltd., and RICHARDS, I. T. July 21, 1936, No. 20179. [Class 40 (iv)] A group selector having two sets of wipers hunts over the selected level with one set of wipers in response to all digits except o and 7, and in response to those digits drops back and responds to a second digit before hunting, one set of wipers or the other being effective according as the first digit is 5 or 7. The invention is applicable also to final selectors. The group selector described is of the kind disclosed in Specification 391,151 which upon release continues its rotary movement to an extreme position. The drop-back movement however takes place over the setting path by operation of the vertical magnet in the manner described in Specification 399,815. Line and release relays A, B energize upon seizure and connect up dialling relay C (left winding) in series with the vertical magnet VM. Dialling tone is transmitted inductively through the centre winding of line relay A. Impulses are repeated to the vertical magnet VM in series with C (right winding), B being short-circuited at each impulse, and relay H pulls up at the first step and short-circuits C (left winding). Assuming the digit received is other than or 7, the relapse of C at the end of the train completes a selfstepping circuit for the rotary magnet RM and places H under the control of test wiper P1, so that it falls back when an idle line is reached and cuts the drive. Relay C (left winding) reoperates, switches through and again connects up H, which is subsequently held from the succeeding switching stage to control release. If no idle line is found, switch through takes place in the eleventh position which is wired to line relay A and a busy signal is transmitted over eleventh step springs S. If the selector is set to the 7th level, post springs NPA are operated, and relay H falls back after a single rotary step, since this level is unwired in the PI bank. Relay DR energizes and connects up the vertical magnet VM, which removes the rotary detent and allows restoration of the wipers. At the same time wiper-switching relay DA operates and locks, so that after a second digit is received hunting takes place over the upper set of wipers. If the selector is set initially to the 5th level, post springs NPA, NPB are operated and drop-back occurs in a similar manner, but relay DB operates in place of DA so that the lower set of wipers remain effective.

Title: Reactive sputtering apparatus and cathode units therefor
IPC: C23C14/34
Filed: 1973-04-27
Abstract: 1443827 Cathode arrangement for reactive sputtering TRIPLEX SAFETY GLASS CO Ltd 4 April 1974 [27 April 1973] 20184/73 Heading C7F  A cathode unit comprises a metal cathode 271 and a shield surrounding the cathode on all sides except that facing the substrate, the shield having spaced inner and outer walls 281, 282 between which a sputtering atmosphere is fed into the working space between cathode and substrate. The cathode may be of elongate rectangular form, and have means 52, 51, to pass cooling liquid therethrough; working gas is supplied at 331 and baffles 283, tallest immediately adjacent 331 and reducing in height with distance therefrom, control distribution of the gas along the cathode. Since no gas passes between 271 and 281, the breakdown voltage is higher than the applied cathode potential, e.g. a spacing of 2 to 6 mm. at 5 x 10<SP>-2</SP> Torr enables a working voltage of -2 to -5 KV to be used. The cathode may be In/Sn used in O 2 /Ar to deposit a mixed oxide on a sheet substrate using several parallel cathodes which are reciprocated to give a uniform coating; the substrate is electrically heated and its temperature measured by a thermocouple.

Patent GB-203307-A (GB)
IPC: B64D33/10
Abstract: 203,307. Lamblin, A. Aug. 29, 1922, [Convention date]. Radiators, aircraft and like, are mounted so that the extent of cooling surface exposed to the current of cooling-air may be varied at will. They may be constructed so that parts contribute to the support of aircraft on which they are mounted, and so that the streams of cooling air and water may be evenly distributed over and through the elements of the radiator. In one arrangement having plate elements 3, Fig. 1, connected to front and rear headers 1, 2 of flattened cross-section, the front header is pivotally mounted as at 5, Fig. 3, in sockets on flexible connections 7 from the engine jacket, while the rear header may be raised or lowered by means under the control of the pilot or driver so as to vary the inclination of the radiator to the direction of the air current. The plates are spaced and stayed by members 17. The radiator may be adjustable about a central inlet and outlet header 20, Fig. 4, or may be suspended at the ends from adjustable links 30, 31, Fig. 6, of unequal length. In another arrangement, shown in Fig. 8, the headers have extensions 35, 36 supported on cams 37, 38, the setting of which is controlled by the pilot. The radiator may be mounted beneath or at the side of the body of aircraft, as shown in plan in Fig. 10, so that the rear header may be raised or lowered, or swung to or from the side of the body. Or the radiator mav be mounted beneath the body of an aircraft so that it may be variably set about a vertical front axis to take up a position in the direction of the current of air due to the action of the propeller. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a construction in which the headers 1, 2 are formed as partitioned chambers of a continuous hollow member 50, Fig. 13 (Cancelled), which acts to assist in the support of aircraft. A further modification is described in which the radiator may be drawn more or less into the body of the aircraft so as to vary the exposed cooling surface. A construction of radiator providing even distribution of water and air is shown in elevation in Fig. 15 (Cancelled). The headers are formed by stamped metal plates 60, 61 riveted together and enclosing pipes 63, 64 having longitudinal slits 65, 66. The plate elements 67, 68 are connected alternately to the parts 80, 81 of the headers so that the air current is divided first by the leading ends of one set of elements and again by the set-back ends of the other set of elements. This arrangement may be applied to radiators having a continuous supporting surface as described with reference to Fig. 13 (Cancelled). This subject-matter does not appear in the Specification as accepted.

Abstract: 941,470. Photo-electric reading systems. SPERRY RAND CORPORATION. June 27, 1957, No. 20401/57, Heading G1A. In a photo-electric device, for scanning a chart having lines of different colours, a circuit is arranged to eliminate undesired signals caused by incomplete attenuation of colours by the filters. Both two and three coloured systems are described. The output from each filter and cell combination contains signals corresponding to the required colour and smaller signals corresponding to the unwanted colour, the latter being caused by imperfect attenuation by the filter. Cancelling of the unwanted signals is effected by adjusting the relative amplitudes of the signals from the filter, cell combinations and applying them in opposition. The scanner 12 Fig. 2, is formed of the rotating cylinder 20 on to the surface of which light is focused from a linear path on the chart 10 by the lens 25. The light from 25 is directed to the intersection of the slits 19 and 21 and as 20 is rotated by motor 22, light from all points along the path is accepted by the scanner. After passing into 20, the light falls on the mirror 23 and is reflected to the half-silvered mirror 14 where it is divided and passes its separate yellow and blue filters, 17,15. Specification 840, 003 is referred to.

Title: Improvements in or relating to pressure devices for friction gears, brakes and clutches
IPC: F16H13/14
Filed: 1924-09-01
Abstract: 221,232. Erban, R. Sept. 1, 1923, [Convention date]. Clutches, friction. - In pressure-applying devices for friction clutches, of the type in which rolling bodies are supported between rings or discs in opposed cavities, each rolling body lies between a pair of independent seating-elements. the two sets of seating-elements being each mounted in a carrier member. Where possible, the parts are machined together to ensure exact similarity. Balls 3, Fig. 1, are lodged between cylindrical hard steel seating-members 1, 2 having conical depressions and carried in borings in rings 4, 5. Except for light loads, the axial thrust is taken by base plates 6, 7. Screw adjusting- means 8 may be provided. The conical recesses may be replaced by V-shaped notches, the members 1, 2 then having flats coacting with flanges on the plates 6, 7 to prevent rotation, or they may have a rectangular cross-section to fit like recesses in the rings 4, 5. The balls may be supported by a cage. In a further modification, Fig. 7, the seating-members 1, spaced by wedges 12, form an annulus between the ring 4 and an outer ring 14, or the members 1 may themselves be wedgeshaped and abut directly. The rings 4, 14 may project over the balls and replace the cage. As shown in Fig. 12, the members 1 may seat in open-ended slots in the ring 4. Barrel-shaped rollers may replace the balls, or cylindrical rollers coacting with convex faces on the seating- members may be used. Where considerable movement occurs between the members 6, 7, the V-shaped depressions have a helicoidal form. In order to ensure equal distribution of pressure, one set of seating-members, when of cylindrical form, may be a fluid-tight fit in the bores of their supporting-ring, fluid-filled spaces behind them being in communication. In the form shown in Fig. 19, fluid chambers 18 are provided in the base plate 6, the members 1 bearing each on a membrane 20 or on a common annular membrane. In a clutch, Fig. 21, a disc 33, connected to a driven shaft (not shown), is gripped between a disc 32 fast on a shaft 39 and a free disc 31, which can be put into initial engagement by a collar 41 and is tightened under drive by the device 1 - - 6,the part 6 being fast on the shaft.
