Title: Magnetic domain wall devices
Inventor: KAENEL REGINALD ALFRED
IPC: G06F7/02
Filed: 1966-08-09
Abstract: 1,127,561. Electric selective signalling. WESTERN ELECTRIC CO. Inc. 9 Aug., 1966 [11 Aug., 1965], No. 35585/66. Heading G4H. [Also in Division H3] A stable magnetic condition including a domain wall can be established in a magnetic medium and advanced towards an output position, the advance being selectively inhibited in response to coded input pulses. In Fig. 1, a nucleation driver 14 creates in a magnetic wire 11, a domain magnetized in the reverse sense to the general state of magnetization. Then the domain is propagated towards a sense winding 13 by a propagation driver 19 which pulses each of two wires 17, 18 positively in turn, then each negatively in turn, then repeats this sequence successively. Each of the wires 17, 18 is wound around magnetic wire 11 in alternating senses at successive spaced locations, the locations for one wire being interleaved with those for the other wire. A further wire 20 is wound on magnetic wire 11 at alternate ones of the locations of wire 18 in senses corresponding to respective bits of a word to be recognized. The nucleation driver 14 is actuated once by a timing pulse preceding an input word and then the input word is applied to wire 20 as the propagation driver 19 advances the domain. Successive bits of the input word reach respective ones of the windings on wire 20 at the same time as the domain, preventing the further advance of the domain and causing its destruction if the bit disagrees with the sense of the winding. Hence the domain survives to pulse the sense winding 13 only if the input word agrees with the word to be recognized. Plugboards may be provided to enable the senses of the windings on wire 20 to be changed. A thin film may be used in place of magnetic wire 11.

Title: Electrolysis of alkali chloride solutions
IPC: C25B9/14
Filed: 1958-11-10
Abstract: <PICT:0850345/III/1> Chlorine and alkali metal hydroxide are produced from an alkali metal chloride brine by electrolysing the brine to free chlorine and the amalgam of the metal, decomposing the amalgam by reacting it with water in contact with an electrode negative to said amalgam to form negative-electrode-seeking ions and the alkali metal hydroxide, the ions being attracted to said negative electrode to produce electric potential, depolarising the negative electrode with a gas containing at least 18% by volume of oxygen, and employing the potential so produced to reduce the electrical potential required from an outside source to electrolyse additional brine.  Sodium and potassium chlorides may be so electrolysed and the depolorising gas may be air or pure oxygen. As shown apparatus comprises a cell divided into two chambers 18, 19 by a partition 17 which does not extend to the bottom of the cell, and anode 23 and a hollow cathode 35 having a porous carbon surface 37 activated with silver.  A circulating layer of mercury seals the aperture 45 at the bottom of the partition.  In operation, an alkali chloride solution in chamber 18 is electrolysed, the alkali metal forms an amalgam with the mercury which then flows into chamber 19 containing water where it reacts to form the alkali metal hydroxide.  Air or oxygen is supplied to the porous cathode through tube 41.  Electrode 62 allows direct connection to be made to the mercury in order to start the cell.

Filed: 1954-12-14
Abstract: 777,273. Controlling aircraft. HOBSON, Ltd., H. M., SMITH, C. P., and GLAZE, S. G. Oct. 19, 1955 [Dec. 14, 1954], No. 36147/54. Class 4. [Also in Group XXIX] A power operated control system for aircraft of the kind comprising a servomotor for actuating a control surface of the aircraft and a relay actuable by electrical signals transmitted thereto under the control of the pilot's control member to operate the input member of the servomotor comprises a normally inoperative mechanical linkage having at its opposite ends lost motion connections with the pilot's control member and with the input member respectively and means operating automatically, in the event of failure in the electrical system, to take up the lost motion at both ends of the linkage to permit manual operation of the input member by the linkage. As shown, the servomotor is of the kind having a fixed piston 11 and a movable cylinder 12 connected to a control surface 10 of an aircraft and is controlled by a pilot valve 13 which is operable by an electromechanical transducer 27 to which signals from a potentiometer 26 actuated by the pilot's control member 16 or from an auto-pilot and/or an autostabilizer are fed through an amplifier. A potentiometer 28 operated by movement of the cylinder 12 sends an electrical feed back signal to the amplifier. A mechanical link 19 has a lost motion connection at one end with the member 16 and at the other end with the pilot valve 13. In the event of failure of the electric supply, solenoids 24, 25 are de-energized to allow springs to operate members 22, 23 to connect the member 19 positively with the control member 16 and the valve 13 so that the pilot can operate the latter directly. Should the valve 13 stick, movement of the member 16 by the pilot will ultimately take up the lost motion with the member 19 which will then operate one of a pair of switches 30 to break the circuit to the solenoids 24, 25 and cause the locks 22, 23 to engage. Additional switches 31, 32 are so connected with the switches 30 that engagement of the locks 22,_23 does not take place should the pilot, during normal operation of the electrical system, move the control member sufficiently to displace the linkage 19 and actuate one of the switches 30. Springs 17 for centering the control column are provided.

Abstract: 797,110. Photographic camera hoods. HEIDECKE, R., and FRANKE, H., [trading as FRANKE & HEIDECKE FABRIK PHOTOGR PRAZISIONS - APPARATE]. Dec. 21, 1955 [Jan. 13, 1955]. No. 36626/55. Class 98(1) A foldable metal hood for the ground glass screen of a reflex camera has the front wall pivotable about a hinge, while each of the side walls comprise a number of articulated parts, which upon raising and lowering of the front wall, are telescopically pivotable relative to one another about a movable axis arranged parallel to the front wall hinge. All movable parts remain above the plane of the ground glass in both erected and collapsed positions. As shown in Fig. 1, the front wall 4 is pivoted at 3 on the frame 1 having rails 2 for fixing in the camera, and may have a view-finder frame 5 closable by a flap and co-operating with a viewing aperture 6 in the rear wall 7, which is pivoted at 8. The projections 9 on the wall 7 during erection and closing of the hood, slide on the edges of the frame 1. The side walls 10 are attached to the front wall 4 by pins 11 on the side walls engaging in slots 12, are also guided by pins 13 thereon engaging the slots 14 in the frame 1, and are connected by pivots 15 to the extensions 16 on a plate 17. The extensions 16 also carry the hinge pins 8 and are guided by pins 19 in the grooves 20 of the frame 1. The plate 17 carries a mirror 18. When the front wall 4 is rocked down to close the hood ,the consequential movement of the side walls 10 draws the plate 17 towards the front wall 4, thus rocking the rear wall 7 and causing the plate 17 with the mirror 18, due to the interaction of the pins 19 and the grooves 20, to assume a position inclined at an angle of 45 degrees to the axis of the eyepiece lens 21 in the rear wall of the frame 1. At the same time, the magnifying lens 23 for viewing the ground glass screen may also come into alignment with the lens 21 to provide a combination of shorter focal length corresponding to the shorter distance of the viewing eyepiece 21 from the ground glass. In a modification, the mirror 18 may be mounted between the extensions 16, and the plate 17 maintained vertical to close in a light-tight manner the rear hood wall 6 in relating to the frame 1.
