Filed: 1933-10-26
Abstract: 428,054. Mechanical switches without quick action. HARRIS, F., Harris' Garage, High Street, Barrow-on-Soar, Loughborough. Oct. 26, 1933, Nos. 29727/33 and 9151/34. [Class 38 (v)] A key-operated lock-switch for controlling the electrical circuits of motor vehicles, comprises a cylindrical casing 10 having its ends closed by insulating walls 12, 13. Rotatable in the upper end wall 13 is a lock barrel 14 formed with a square extension 17 terminating in a round spindle 18 having a bearing in the end wall 12 in which are fixed contacts 24, 25, 26, 28 and 29 having binding posts 22. A movable contact arm 20 is fixed at its centre to an insulating bush 23 which fits on the squared spindle 17 surrounding which is a spring 21 for biassing the arm 20 against the fixed contacts. The lock barrel is provided with tumblers 19 which, in the off position with the key 15 removed, engage in a recess 30, Fig. 4, in the central opening of member 13. The contact arm 20 bridges contacts 28, 29, to earth the ignition and by turning a knurled knob 16 the barrel 14 can be turned so as to cause the contacts 24, 25 to be bridged to connect the battery 37 to the side and tail lights 40, 41. The tumblers 19 now rest against a projection 31 and the switch cannot be rotated farther unless the key 15 is inserted to cause the tumblers to be withdrawn and projected oppositely into a wide recess 32. The switch can now be turned so that the arm 20 lies over the gap between contacts 25, 26 and this connects in circuit, in addition to the side and tail lights, the head lights 39 and the ignition coil and any other electrical devices through a switch box 42 and also the starter 38 through a switch 43. If the switch is rotated farther, the arm 20 bridges only contacts 24, 26 and the side and tail lights are switched off. If the key is withdrawn in the last two positions, the tumblers engage in the recess 35, but due to a sloping edge to stop 31 the switch can be rotated back to the first positions without the key, but not in the other direction. Thus on parking the car, the side and tail lights may be illuminated without using the key, but the ignition and starter are locked against unauthorized use. A modified circuit is shown in which the side and tail lights have no earth return. Reference has been directed by the Comptroller to Specification 407,967.

Title: Movable member displacable using a linear induction motor
IPC: B60L15/00
Filed: 1971-06-25
Abstract: 1350660 Control of linear motors MERLIN GERIN 25 June 1971 [6 July 1970] 29835/71 Heading H2J [Also in Division E2] A linear induction motor has a moving armature connected to a movable member, e.g. a sliding door and stationary field windings, comprising two independent sets of windings, for moving the door in opposite directions, connected to a polyphase supply through controllable semi-conductor elements, e.g. triacs. In the embodiment, upon a request to open the door, e.g. from a push-button, a high frequency signal from clock 70 is modulated by the logic addition of signals from memory 52 and timer 54, both initiated by the request. The modulated signal is applied to triacs 72, 72<SP>1</SP>, 72<SP>11</SP> to energize motor field windings 40, 40<SP>1</SP>, 40<SP>11</SP>, provided a delay 64 has not timed out, i.e. the door is not stuck. The excitation is continuous for an initial period, determined by timer 54 to overcome inertia, after which the excitation is by pulses. The excitation is terminated when an end stop is reached, then timer 54 is again initiated, so that after a delay, windings 42, 42<SP>1</SP>, 42<SP>11</SP> are excited through triacs 78, 78<SP>1</SP>, 78<SP>11</SP> to close the door using modulated pulses from clock 70, the excitation ending as a further end stop is reached. To make the motor thrust independent of the winding voltage, the excitation pulse width is modified by a voltage dependent signal. Constructional details of the system are described with reference to Fig. 1 (not shown). Braking may be pneumatic or electro-magnetic as described in Specification 1,303,526.

Title: Improvements in the physical or chemical treatment of fine powdery materials having a controlled granulometry
IPC: C22B1/02
Filed: 1962-08-03
Abstract: In the production of metallic compounds from the sulphides, carbides, oxides, and borides, of metals or metal alloys, particulate material is predispersed by suspension in a non-conductive fluid (liquid or gas) which is then ionized to produce a finely divided suspension of the material.  The particles in the suspension repel each other by virtue of their electrical charges, and said suspension is transferred to a reaction chamber (which may be heated) and then to a separation and cooling unit.  The non-conductive fluid may be a reducing or oxidizing fluid or may be inert, in which case the reactant is added at a later stage. Oxidation of sulphides to oxides, reduction of magnetic iron oxide, production of nitrides from metals are referred to.  In particular iron-cobalt sulphide and cupronickel sulphides are converted to oxides.  The product is separated if desired by electrostatic precipitation.
