Title: Improvements in or relating to teaching machine installations
Inventor: LING JAMES FRANCIS
IPC: G09B7/08
Filed: 1963-06-12
Abstract: 1,041,245. Teaching machines. LAMSON TECHNICAL PRODUCTS Ltd. June 11, 1964 [June 12, 1964], Nos. 23420/63 and 24476/63. Heading G5R. In a teaching machine installation a master teaching device and an ancillary teaching device each feed pulses to respective counters, and when the counter readings bear a predetermined relationship to each other one of the teaching devices is stopped. The installation may be as in Specification 983,165 and the teaching programme may be either branched or linear. The ancillary teaching device may be a tape recorder which is required to play-back ancillary information during some (but not necessarily all) frames of the main teaching device. The web of the main teaching device and the tape of the recorder both carry conductive metal strips which make contact with brushes to operate the counters which are multiposition rotary switches driven by solenoids. The tape recorder rewinds if the main teaching device is reversed.

Abstract: 813,119. Batteries. ACCUMULATORENFABRIK A.G. Aug. 15, 1955 [Aug. 16, 1954], No. 23440/55. Class 53. An electrode for an alkaline accumulator is made by compressing pulverulent active material into a metal frame which is to constitute an edge protection for the finished electrode. As described, an initially-L-sectioned, rectangular, metal frame 1, having a metal insert 2 of expanded metal or netting electrically connected to it, is filled with pulverulent active material. The active material is then pressed to form a compact body 3<SP>1</SP> and the projecting web of the frame is bent down and embedded in the surface of the compressed material.

Title: Improvements in batteries, electric accumulators and electrolysing apparatus
IPC: H01M4/06
Filed: 1925-09-22
Abstract: 244,417. Soc. Anon. le Carbone. Dec. 10, 1924, [Convention date]. Electrodes; absorbents.-An absorbing and depolarizing material for electrodes containing powders with porous grains, comprises a substance possessing, naturally, the double property of being very absorbent to gases and impermeable or only slightly permeable to liquids. Such a substance may be a dehydrated colloidal gel-e.g. the gel of silica or aluminium. The gel of silica is obtained by reacting on a silicate-e.g. sodium silicate-with hydrochloric acid and by working and then drying and heating the product in progressive stages to about 500 C. A paste, which may be compressed into a plate electrode or forced into a grid of lead or carbon, is formed by mixing 200 grams of powdered product with 1 kilogram of powdered lead or an oxide of lead and moistening the mixture with 100 c.c. of water, preferably acidulated with 10 per cent of sulphuric acid. The gel may be rendered completely impermeable to liquids by exposing it in powdered form to hydrocarbon vapours or, after moistening, by mixing it with a rubber solution and subsequently evaporating the rubber solvent.

Abstract: 185,747. Mignet, H. M. F. Sept. 7, 1921, [Convention date]. Void [Published under Sect. 91 of the Act]. Aeroplanes; steering and balancing. - The wings 1 of an aeroplane are fitted with ailerons 2 the incidence of which may be varied independently of each other. The ailerons 2, which are hinged at points 3, have a span equal to that of the wings 1 and are connected to a control lever 4 by means of wires 5 passing over pulleys 6, the angle at which the wires 5 meet the lever 4 being such that movement of the lever 4 to the left or right imparts opposite movement to the ailerons or moves one and not the other, whereas a backward or forward motion moves both simultaneously down or up. The tail 7 is positioned in the same plane as the main wings 1 (or in a plane parallel thereto) at an equal inclination, and is of such width that the machine is stable for all angles of the ailerons. The upper surface of the tail 7 forms a dihedral angle, as shown in Fig. 9, the apex of which is pivoted to the fuselage. Steering is effected by lateral inclination of the tail to the right or left about an axis in the line of flight, by means of the foot-operated rocking lever 10, which controls the tail through cables 11 passing over pulleys 12.

Abstract: 970,003. Control of A.C. motors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. June 17, 1963 [June 25, 1962], No. 24395/62. Heading H2J. A three-phase induction motor has, carried on its rotor, rectifiers 2 for rectifying the rotor current, and a silicon controlled rectifier 5 for interrupting and restoring cyclically the rectified current. A radio-signal transmitter 10 is carried on the stator and sends a signal to radioreceiver 8 which causes the rectifier 5 to switch on and off. By regulating the relative lengths of the on-off periods, the mean power in the rotor circuit is modified, and hence the speed of the motor. In another arrangement, the signals supplied to the controlled rectifier are conveyed through slip-rings. Alternatively, a rotary pulse generator has its armature attached to the rotor and connected to supply signals to the controlled rectifier through leads in an axial hole in the motor shaft.

Title: Improvements in and relating to the chlorination of hydroxy anthraquinones
IPC: C07C46/00
Filed: 1922-07-08
Abstract: a -Oxyanthraquinones are chlorinated in suspension in strong or fuming sulphuric acid.  1-Oxyanthraquinone yields 1-oxy-4-chloranthraquinone and 1-oxy-2 : 4-dichloranthraquinone, quinizarin yields chlorquinizarin; 1 : 6- and 1 : 7-dioxyanthraquinones are also mentioned as parent materials. The chlorination is assisted by the presence of a small proportion of iodine.  The sulphuric acid solution of 1-oxy-4-chloranthraquinone may be directly hydrolyzed to quinizarin by adding boric acid and heating; the resulting solution of quinizarin may be reduced to leucoquinizarin by means of aluminium.  The sulphuric acid solution of 1-oxy-2 : 4-dichloranthraquinone may similarly be directly hydrolyzed to chlorquinizarin.  Examples of the several processes are given.
