Patent GB-1468753-A (GB)
Title: Associative memory
IPC: G11C15/00
Filed: 1974-05-09
Abstract: 1468753 Associative memory HONEYWELL INFORMATION SYSTEMS Ltd 8 May 1975 [9 May 1974] 20436/74 Heading G4C An associative memory comprises a plurality of cells 20 each coupled to a common control circuit 10 by a common bus 17 each memory cell 20 comprising a recirculating shift register 30; a comparison circuit 31 which compares the contents of the register 30 with a key word from the common control; a bi-stable 33 controlled by the comparison circuit and a gate 34 controlling the transfer of data from the shift register to the control circuit. The common control circuit (Fig. 1) has three shift registers 12, 13, 14 which are shifted in step with the memory register 30 by a clock 11; register 12 holds the key word; register 13 contains l's in the positions of the effective bits of the key word and 0's for the don't care bits; register 14 holds the word read from or to be read into the relevant memory cell. At the start of a search a control 16 signals on line 26 to set the bi-stable 33 which enables the gates 34 of all memory cells containing data. All the registers 30 thus begin to feed register 14 by common line 29. At each step the contents of each register 30 is compared by the exclusive-OR gate 31 with the corresponding bit of the key word; AND- gates 32 are enabled by the output of register 13 only during the effective bits of the key word. When gates 31, 32 detect a non-coincidence between the memory word and the key word the bi-stable 33 is reset and gate 34 is disabled. At the end of a cycle on the gate 34 of the cell selected by the key word will remain enabled and the data can then be read to register 14. Each cell also contains gating circuits for reading data from register 14 into the selected register 30. A clear entry signal on line 25 from write control 15 sets a bi-stable 37 of the selected cell which then disables gate 34 to prevent read-out and enables the gates which allow data on line 24 to overwrite the previous data in register 30. An inhibit chain 18, 40a, 40b which connects all the cells in sequence causes new data to be read into the first available empty cell. In a more elaborate system (Figs. 3, 4, not shown) there is provision for dealing with multiple responses during searching and for storing data records extending into several cells and for reacting them in sequence.

Abstract: 571,775. Photo-electric apparatus for use with measuring instruments. MORRIS MOTORS, Ltd., and SKINNER, P. G. Dec. 8, 1943, No. 20525. [Class 40 (iii)] In apparatus in which the movement of a feeder c following the surface of a workpiece b is linked to a reflector g reflecting light from a source i on to a pair of photo-electric cells m, variations of the source i are compensated by a second reflector p movable under control of the voltage exciting the source i so as to deflect the light beam in a direction at right angles to the deflection produced by the reflector g. The reflector p may, for example, be connected to a moving coil q excited in parallel with the source i or may be operated electrostatically. The cells m are connected in opposition to a circuit containing a variable resistance and a galvanometer, Fig. 2 (not shown), which thus responds to the difference in illumination of the two cells.

Title: Improvements relating to cathode ray tube envelopes
Inventor: COLBORNE RONALD HENRY
IPC: H01J9/24
Filed: 1953-07-24
Abstract: 750,333. Cathode-ray tubes. ELECTRIC & MUSICAL INDUSTRIES, Ltd. July 26, 1954 [July 24, 1953], No. 20553/53. Class 39 (1). A cathode-ray tube such as a television projection tube has a window of glass which has been toughened, i.e. subjected to a tempering process which leaves it in a state of residual strain. The window is sealed to the glass or metal body portion remote from the neck by a low-temperature glaze, and is not subsequently subjected to any temperature high enough to anneal the glass, i.e. to eliminate the residual strain. The strain may be induced either before or after the window is sealed in position; in the latter case, normal heat-sealing techniques may be used. It may be of advantage to toughen the whole tube, not only the window.

Filed: 1958-06-28
Abstract: 888,514. Electromagnetic couplings. PUMPINDUSTRI A.B. June 28, 1958, No. 20799/58. Class 35. [Also in Group XXVI] The impeller 28 of a centrifugal pump is journalled on a stationary shaft 32 and driven by an electric motor 16 through a magnetic coupling comprising permanent magnet rings 62, 63, carried by a non-magnetic driving member 61 and permanent magnet rings 56, 57 carried by an extension of the impeller, a cup-shaped non- magnetic diaphragm 66 being interposed to prevent leakage of pumped liquid. An outer rim of the diaphragm 66 is clamped between the pump casing and a ring 14 that is interposed between the pump and motor casings. Each magnet ring is formed with a circumferential series of magnetic poles, separated by non- magnetic material. The axial dimensions of the magnet rings may be 8 mm. for the rings 56, 62 and 12 mm. for the rings 57, 63. Different combinations of these two sizes may be used to obtain total axial dimensions of 8, 12, 16, 20, 24 mm. &c., to provide a desired torque capacity. The impeller 28 and a clamping- ring 58 are of non-magnetic material such as light metal, brass or synthetic resin. If the rings 56, 57 are of ceramic material they may be a loose fit on the impeller extension and be held concentrically on the latter by means of 0-rings of rubber or the like located in annular grooves. Auxiliary vanes 75 on the back of the impeller reduce or reverse the downward axial thrust of the impeller and also prevent iron particles or other impurities in the liquid from being deposited on the magnet rings.

Patent GB-984939-A (GB)
Title: Improvements in power plants comprising at least one freepiston engine generating gas under presure and a driven machine, such as a turbine
IPC: F02B71/00
Filed: 1962-05-31
Abstract: 984,939. Combustion product power plant. SOC. D'ETUDES ET DE PARTICIPATIONS EAU, GAZ, ELECTRICITE ENERGIE S.A. May 31, 1962 [Nov. 9, 1961], No. 21052/62. Headings F1B and F1Q. In a power-plant comprising at least one freepiston engine generating gas under pressure and a machine driven by the gas, means are provided for by-passing at low loads some of the pressure gas and further means are provided to regulate automatically the quantity of fuel injected at low loads on the driven machine in dependence upon the outer dead point reached by the free piston, and at higher loads, in dependence both upon the speed of the driven machine and upon the piston outer dead point. The piston of a fuel injection pump 6 is actuated by a lever 14, pivoted at 15, striking a push rod 17. A member 18 regulates the quantity of fuel injected and is actuated by a piston 27 which is subjected on one face to a control liquid and on the other to the action of a spring 28. The position of the piston 27 is dependent upon the quantity of liquid supplied to the cylinder 29 and the quantity of the same liquid removed by a pump actuated by a cam 40 on the lever 14, the stroke of the pump being proportional to the stroke of the free piston 4, 7. For a constant supply of liquid to the cylinder 29, an increase of the free piston stroke will result in a reduction of the amount of fuel injected and vice versa. A low loads, a by-pass valve 20 is open and the quantity of control liquid supplied is practically constant. The liquid is supplied from a pressurised source through conduits 50, 51, 44, past a pressure reducing valve 53 and a control valve 42 to a conduit 32, and an orifice 35 of reduced cross-section which reduces the pressure fluctuations in the liquid. As the turbine speed increases, a governor 49 opens a valve 54 in a conduit 52 and the control liquid is supplied to the cylinder 29 at a pressure proportional to the turbine speed. In the event of undesirably high gas pressure at a particular turbine load, a safety valve 77 is opened by the gas pressure and the control liquid pressure reduced. The control liquid also acts on a piston 57 to close the by-pass 20. The by-pass closes when the pressure in the conduit 52 equals that in the conduit 51. A stop 61 on a rod 62 determines the position of the piston 27 for starting. The pressure in the reservoir 12 is communicated via a conduit 67 to a piston 65 which overcomes the action of a spring 63. A spring 66 moves the rod 62 to open an orifice 64 thereby allowing the control liquid to act on the piston 27. In an alternative embodiment the member 18 is connected to the piston 27 via a linkage at a pivot point thereof. The linkage is also connected to a slide valve of a servomotor which prevents an oscillatory movement of the member 18 due to pressure fluctuation in the control liquid.

Title: Improvements in and relating to tarnish-resisting alloys and methods of rendering tarnishable metals or alloys tarnish resisting
IPC: C25D3/64
Filed: 1930-07-11
Abstract: Alloys.-Tarnish-resisting alloys consist of or comprise silver and iridium, with the silver predominating.  The alloys may be made by melting the metals together, or by electrodepositing iridium on silver and diffusing the iridium into the silver, for example by heat; or by simultaneously depositing iridium and silver on a suitable base and then stripping the deposit from the base; or by depositing alternate layers of iridium and silver on a base, diffusing the iridium into the silver, for example by heat, and stripping the deposit from the base.  Other metals, for example palladium or zinc, may be added.  Electrolysis.-The tarnishing of articles formed of silver or of silver alloys is retarded or inhibited by electrodepositing iridium thereon and thereafter diffusing the iridium through the silver, for example by heat; or iridium and silver may be electrodeposited simultaneously from a common solution on to a suitable base which may in this case be of nickel-silver or other suitable metal.
