Patent GB-1070452-A (GB)
Title: Magnetic memory devices
IPC: G11C11/04
Filed: 1965-03-16
Abstract: 1,070,452. Magnetic data storage apparatus. H. MAEDA. March 16, 1965 (March 17, 1964], No. 11155/65. Heading H3B. In a matrix consisting of conductive wires 1, Fig. 3, coated with magnetic material 2, which form the bit lines, the word lines, W, are formed by conductors which are either woven with, or printed on an insulating plate covering, the bit lines, and each word line has at least two auxiliary lines, S, parallel with it and so connected to it that they generate a net flux in any one bit line which opposes the flux generated in the same bit line by the word line. The easy direction of the magnetic material on the wires is circumferential, and the portions of the magnetic material in the vicinity of each crossover of a word line and a bit line constitute the storage elements. The auxiliary lines, S, may be connected in series with one another and with the word line W, and each may have a resistor R connected across it to limit the current flowing in it and hence the flux generated by it. Alternatively, Fig. 4 (not shown), two auxiliaries S may be connected in parallel with one another, and in series with the word line; and further, Fig. 5 (not shown), each of the two auxiliaries connected to one word line may be placed adjacent the neighbouring word line. A plurality of auxiliary lines may be connected to each word line, Fig. 6 (not shown). An experimental fabric, Fig. 12 (not shown), has a plurality of bit lines 3, and a plurality of auxiliary lines S1, S2 etc. arranged at increasing distances from the main word line W 0 , so that the voltage across each auxiliary indicates the flux, due to a given current Iw in the word line, at various distances away from it. The variation of flux with distance from the word line is plotted, Fig. 13 (not shown); and a further set of curves, Fig. 15 (not shown) may be derived to indicate the current (ordinate in Fig. 15) required in an auxiliary line placed at any particular distance (abscissa, Fig. 15) from the word line, in order to cancel the flux at that point. The currents flowing in a plurality of auxiliary lines of a storage matrix, Figs. 16, 17, 18 (not shown), may then be adjusted to match the curves of Fig. 15 by means of shunt resistors, or by using wires of various resistivities for the auxiliary lines. In addition, one or more auxiliary lines may carry a current in an opposite direction to the remainder, the net resultant flux being of the value required to oppose the word line flux, this arrangement serving to reduce the flux due to the auxiliaries in the event of an excessive current flowing therein. Figs. 7 to 11 (not shown) depict various embodiments in which the word and auxiliary lines are printed on an insulating plate 6.

Title: Improvements in transistor amplifiers or relay systems
IPC: H03F3/217
Filed: 1960-03-30
Abstract: 921,656. Converting; automatic voltage control systems. GENERAL ELECTRIC CO. March 30, 1960 [April 2, 1959], No. 11195/60. Classes 38 (2) and 38 (4). [Also in Group XL (c)] In a controllable self-oscillating transistor converter (see Group XL (c)), the signal controlling the conduction of the transistors may be derived from the output of the circuit to provide a regulated output voltage. In one embodiment, Fig. 15, the D.C. source 8 is coupled to windings 2, 3 on the saturable output transformer 1 by transistors 11, 12. Feed-back windings 24, 25 are coupled to the transistors by circuits which include diodes 14, 15 so poled that the feed-back voltage is only effective to cut the transistor off. Additional windings 52, 53 are provided to increase the negative bias voltage available so increasing the transistor gain to improve the regulating characteristic. The control voltage, which in the absence of a " cut-off " voltage biases the transistors on, is derived from windings 2, 3 via diodes 50, 51 and after amplification by transistor 45, the signal is applied to the bases of transistors to control their conduction. A Zener diode 46 is included in the emitter circuit of transistor 45 as a reference source. A D.C. output is provided by the rectifier bridge 42 and in an alternative embodiment, Fig. 14 (not shown), the input to the transistor 45 is derived from this output instead of directly from windings 2, 3.

Title: Improvements in and relating to electric lamps
IPC: H01J17/00
Filed: 1935-04-11
Abstract: 455,009. Discharge lamps. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London, SPORBORG, H. N., 42, Hillmorton Road, DAVIES, L. J., 147, Murray Road, and FAIRBROTHER, J. A. V., 110, Eastlands Road, all in Rugby, and GABOR, D., 30, Falk Miksa Ucca, Budapest. April 11, 1935, No. 11268. [Class 39 (i)] The " plasma-filter " of the lamp described in Specification 442,307 is of metal wire gauze woven or welded and coated with insulating material at least on its outer surface facing the lighting space and on the walls of the openings in the gauze for the passage of the electron beams. Such " plasma-filters " with small holes are particularly suitable for lamps operating with a plasma in the inner space enclosed by the " plasma-filter" as well as in the lighting space, and the surface of the gauze facing the plasma in this inner space may be uncoated so that the gauze serves as a starting electrode when connected to the anode through a high resistance. For round or square holes in the coated gauze, the lateral dimensions of each hole are not greater than 4/S #m/M where m and M are the mass of an electron and of an ion of the gas filling and S is the maximum number of secondary electrons produced at the gas density obtaining in the hole by an electron having a velocity not greater than that corresponding to the lamp voltage. The depth of the holes is not much less than their lateral dimensions ; numerical details are given for a lamp filled with neon at 1 mm. pressure at 0‹ C. The coating may be of oxides, silicates, phosphates, borates or mixtures thereof of metals such as aluminium, magnesium and beryllium or may be of powdered quartz or glass or enamel. After the gauze has been flattened by pressing or rolling, the coating is applied to it by dipping or by spraying from the side to face the lighting space or by electrophoresis in a colloidal solution of refractory oxide and the coating is fired in hydrogen to form a smooth surface. In a modified process, the gauze is coated with nitrates converted into oxides on firing. In another process, the metal of the gauze is superficially oxidized ; the wire of the gauze is of zirconium or is coated, before or after forming into gauze, with a metal such as aluminium or magnesium by distillation, sputtering, electrolysis or drawing through molten metal, the metal being then oxidized by heating in air or steam or by anodic polarization. The Provisional Specification describes also a " plasma-filter" of metal insulated as a whole but coated with material such as boron or graphite, instead of insulating oxides, &c. to reduce sputtering, and refers also to Specification 441,204.
Patent GB-437499-A (GB)
Title: Improvements relating to automatic electric motor starting devices for telegraph apparatus
IPC: H04L12/12
Filed: 1935-04-11
Abstract: 437,499. Controlling telegraph traffic. GRIFFITH, R. G., Montclair, Crewes Avenue, Upper Warlingham, Surrey. April 11, 1935, No. 11285. [Class 40 (iii)] In a device for stopping a telegraph motor when signalling has ceased for a prescribed period, and for starting it when signalling begins, the actuating-member does not reach its idle position till after the motor has been switched off. The Figure shows the device in the idle position. On the arrival of signals, the movement of the armature 2 permits the actuating-member 4 to fall, under the influence of its weight 9, until the latter strikes the arm 10 and closes the motor switch by means of a toggle (not shown) connected to the shaft 1. The shaft 5 is then driven slowly through worm gearing 8 and the member 4 is hooked to it by engagement of the pawl 3 with the ratchet 7. Received signal impulses disengage the pawl, however, by moving the shaft 5 through the part 13, and the member 4 then slips back under the influence of its weight 9. When signalling ceases the weight 4 eventually reaches the upper arm 16 by means of which it opens the motor switch. It then falls into the position shown. A spring may be used instead of the weight 9.

Abstract: 799,679. Liquid fuel fired boilers; oil stoves; dampers. LOVEGREEN, A. T. Jan. 15, 1957 [Anril 13, 1956], No. 11354/56. Class 126 [Also in Groups XII and XIII] An annular boiler 10 and an air-heating chamber 31 are heated (see Group XIII) by gases rising from a combustion chamber with a refractory lining 19 and hearth 32, on or above which oil is vaporied for combustion. The oil passes from a constant head tank through a pipe 42 and tap 41, controlled by a knob 40, to a nozzle 43 in a tube 39 spider-supported in a large air tube 14 down which the oil falls in a thin stream. The flow of air down the tube 14 is controlled by disc-damper 44 sliding on the tube 39 so as to be raisable by the use of a bifurcated wedge 47 operated by an external handle 51. An inner casing 17 surrounds the boiler and forms a space 21 above it from which flues 23 pass through the air-heating chamber 31. The inner casing also forms the combustion chamber which is closed at the bottom by a removable cup 33 having a ring handle and bearing the hearth and adjustable for height since slots 36, Fig. 4, in the cup coact with radial projection 34 on the outside of the inner casing 17. A tube with a sight glass 54 normally closes a tube 53 which is used for the insertion of a taper when the heater is started by the use of paraffin oil.

Abstract: 399,578. Veneering. SCHUCHER, A., 14, Kasernengasse, BAUER, K., 6, Stiftgasse, and VAVRA, K., 8, Pilgramgasse, all in Vienna. April 21, 1932, No. 11504. Convention date, Aug. 17, 1931. [Class 145 (ii).] The veneer and work piece are enclosed in an airtight container, composed partly or wholly of pliable material, which is then evacuated to exhaust the air from the pores of the veneer and work piece, the atmospheric pressure acting on the walls of the container effecting the pressing on of the veneer. The glued veneer e, Fig. 1, and work piece f are placed between pressure plates g in a rubber bag a lined with cloth k ; the bag a is closed by a clamp b and evacuated, water vapour being absorbed by calcium chloride &c. in a container i. Pressures greater than atmospheric are obtained by having the plates g of greater area than the work. Curved work p, Fig. 2, is placed with the glued veneer n in a container s by means of supports r ; the container s is closed by a rubber bag a airtightly secured at l and is exhausted, causing the veneer to be pressed on the work. Alternatively, suitable supports may be used with the apparatus shown in Fig. 1 for veneering curved work.
Patent GB-115196-A (GB)
IPC: F02D9/00
Abstract: 115,196. MacDonald, A. E., and Sheffield Simplex Motor Works. Nov. 9, 1917. Cylinders, pipes for.-The throttle valve of a carburettor is so connected to an air valve thereof or to a valve on any other part of the induction system, e.g. through a lost-motion device that, as the throttle is opened the best proportions of air and fuel are maintained, but as the throttle is moved in the closing direction the air supply remains at such a value that the mixture strength is impoverished. The spindle D' of the throttle valve D carries a finger D<2> which can engage, with lost motion, adjustable stops E<4>, E<5> carried by lugs on a rotatable disk E provided with ports E' which may register more or less with ports F' in a disk F which may be adjusted angularly through an arm F<2>. Thus as the throttle is opened, the ports E', F' register to admit more air but as the throttle is closed, the air port area is unaltered until the finger D<2> engages the stop E<4>. The mixture is therefore more dilute.

Abstract: 1460084 Testing EEG systems BECKMAN INSTRUMENTS Inc 15 March 1974 [30 April 1973] 11550/74 Headings G1E and G1N In a test system for identifying open circuit electrodes (i.e. unattached) of a multi-electrode electro-encephalograph system, each electrode receives a burst of (four) pulses, the amplitude of the pulses being sufficiently low that it is less than the signal-to-noise ratio of the amplifier of the EEG system, so that the test signal burst is undetected in the output of the EEG system unless an "open circuit" condition occurs therein. Pulse signals from a 400Hz squarewave generator 12 supply a seven stage binary counter 15, and the outputs of the counter provide a 25Hz signal and a 3.125Hz signal. These signals are supplied as shown via AND gates 21, 24, 28 to provide bursts of pulses alternately on conductors 30 or 31, Fig. 2 (not shown). As shown AND gates 34, 61, 62 .... are connected alternately to different ones of conductors 30, 31 and to different outputs of a decade counter so that each AND gate 34 or 61 or 62 &c. gates a burst of pulses in sequence. Each gated burst is directed to a pair of electrodes 300 and 301, or 302 and 303 &c. via circuit networks constructed as shown to ensure that the burst on each electrode is of opposite polarity with respect to the other electrode. Thus by inspecting the EEG output Fig. 3 (not shown) for "tell tale" bursts of four pulses any open circuit electrode can be detected.

Abstract: 623,477. Grinding and polishing; workholders. OFFEN, A. April 30, 1947, No. 11653. [Class 60] [Also in Group XXII] A work table 13 is mounted on a base 11 for limited rotation under the control of resilient means, such as a spring 19, and the degree of rotation of the table under the torque imparted to the work during a lapping or like operation is indicated by a scale on the base so that a visual indication of the amount of cut is given and the need for sensitive. feel in applying the cut is avoided : the return of the table to the zero position also indicates, that the cut applied has been worked out. The work table is preferably made of light alloy and has four quadrantal steel segments 27 overlying slots 29 so as to provide T-slots for the attachment of the work : a wall 22 and a hollow hub 15 provide for the retention of lubricant or coolant. For adjusting the initial tension of the spring, one end may be attached to a rotatable sleeve 17 which may be locked in the adjusted position by a screw fitted radially in the base. The Provisional Specification also describes the resilient means as comprising compression springs fitted between radial lugs on the table and fixed points on the base.

Title: Improvements in and relating to the compressing and briquetting of raw materials
IPC: B30B15/00
Filed: 1939-04-18
Abstract: 528,117. Extrusion moulding-machines. DORSTENER EISENGIESSEREI U. MASCHINENFABRIK AKT.-GES. April 18, 1939, No. 11691. Convention date, May 2, 1938. [Class 87 (ii)] Oxidizable raw material, e.g. magnesiumcontaining material, is compressed and extruded by a piston extrusion press to form a continuous rod which on emerging from the nozzle is subdivided by striking against a mandrel. In the press construction shown, detachable plungers 1 are adapted to be reciprocated by connecting-rods 3 and a crankshaft 2. The plungers extend through water-cooled stuffing- boxes 7 into chamber 8 which receive material fed laterally from hoppers by conveyer worms. The shaft of each worm passes through a stuffing-box and air is prevented from entering the hoppers. Above each chamber is an outlet pipe 14 for the escape of gases..The front of the press casing 16 is closed by a water-cooled wall 15 to which is attached a hermetically-sealed box 18 containing extrusion nozzles 19. The nozzle aperture may be adjusted by the use of a key 47 passing through a stuffing-box 22. Adjustable breaking mandrels 26 are provided opposite the nozzles 19. The extruded material is conveyed away through one or other of two funnels 28, 29, depending upon the position of a flap 30. The funnel 28 is for the withdrawal of sample pieces. The box 18 is provided with inlet 32 and outlet 33 for the passage of inert gases. When, for example, two press plungers are provided in twin arrangement the holder 5 is rotatably mounted on the cross-head guide 4 ; to change the plungers it is then unnecessary to dismount the wall 15 and filling chamber 8. Or plungers in twin arrangement may be connected to oppositely disposed cranks on a shaft and a separate box 18 be associated with each plunger.
