Abstract: 1,235,254. Vehicle wheels &c. NATIONAL STANDARD CO. 10 June, 1969, No. 29442/69. Heading B7C. [Also in Divisions B3 and C1] A composite body comprises a matrix reinforced with a number of discrete wires 8, the wires being of circular cross-section with intermittent portions 11 of rectangular cross-sections. The wires are deformed by being rolled between rolls 5 and 6, the roll 6 being notched at 7 to leave circular cross-section portions 12 in the wire. The rolls may draw wire from a supply, or rubber-coated rollers or a capstan may pull the wire through the rolls. The body can be of concrete, plastics, rubber, ceramics, metal or paper, and the wires of low carbon steel. The wires may be coated with an organic silicon compound when used with plastics; with phoscoat, silane, oxalate, or cadmium when used with concrete; or with brass when used with rubber. In an example, a low-carbon, hard-drawn wire of 0À010 inch diameter, was intermittently flattened to give portions of 0.005 x 0À016 inch. The wires may, for example, be incorporated in the tread or carcass of a pneumatic tyre, the adhesion of the wires with the rubber being improved by coating the wires with brass.

Abstract: 1,181,722. Control of D.C. motors. HANS STILL G.m.b.H. 27 June, 1967 [6 July, 1966 (2)], No. 29701/67. Heading H2J. In a battery powered truck having a stepless, pedal operated, speed controller the effect of a rise in the signal from this controller is delayed, and the controller comprises a variable inductance k1 energized from an astable multivibrator U1 to set up a control voltage on capacitor R2. This is applied, in opposition to the voltage of a Zener diode n2, to the base of a transistor n6. The emitter voltage follows that of the base, but a rise is delayed by the time constant of RC circuit r3, k3; a drop is not delayed since k3 can discharge through n6. The emitter voltage can be applied to further transistor circuits to sequentially operate relays d1, d2, d3 to switch resistors in the motor circuit, or an unspecified thyristor motor control circuit can be controlled by the voltage at AA and a relay connected as d1 be used for bridging the thyristor for full power.

Filed: 1973-06-22
Abstract: 1473499 Cable joints or terminations BICC Ltd 21 June 1974 [22 June 1973] 29733/73 Heading H2E In a method of jointing or terminating a cable the dielectric 4 is overlayed with a vulcanizable layer 9 of ethylene homo- or copolymer applied to cover at least the tapered surface 5, heat-shrinkable polyethylene tape 10 is then wound on to build up a thickness greater than that of the untapered dielectric, and the joint or termination is heated to vulcanize layer 9 and bond it to the dielectric 4 and to the tape 10 and to shrink and bond the turns of tape 10. The outer surface of tapes 10 may be restrained against expansion. In the joint shown, for a 15 kV cable, semi-conducting vulcanizable ethylene-polythene elastomer tape 8 is applied over the ferrule 3 up to the cut ends of the conductor screen 7. Insulating tape of the same elastomer is then applied as a single layer 9 to abut but not overlap the dielectric screen 6. A replacement screen 11 is formed using a single layer of semi-conducting carbonloaded polyethylene tape, irradiated but not heat shrinkable, covered by two layers of similar but 40% heat shrinkable tape followed by a temporary layer of fluorinated ethylene-propylene tape 12. A split brass tube 16 acts as an oven and the temperature, raised by the hand application of a propane flame or otherwise, monitored by the thermocouple 14. In another embodiment (not shown) two layers of 40% heat shrinkable polyethylene tapes are substituted for the replacement screen 11. After heat treatment the dielectric screen, outer conductor 1 and sheath are restored conventionally. In a further embodiment (Fig. 2, not shown) layers 12, 13 of tapes woven from wire and oven 16 are replaced by a close fitting mould 17. The dielectric 4 is preferably tapered by a knife or edge tool and may be from a wide range of polymeric materials some of which are specified. The tape 10 may be modified by the inclusion of a small amount of comonomer such as vinyl acetate or ethylacrylate at the formation stage of the tapes.

Title: Improvements in and relating to shutters for fans

Abstract: 881,806. Ventilators. WEAVER, G. R. E. Sept. 14, 1959 [Sept. 17, 1958; May 22, 1959], Nos. 29811/58 and 17405/59. Class 137 [Also in Group XXVI] An automatically controlled hit and miss type ventilator for use with a fan comprises a shutter 7 rotatably driven by the spindle 21 of a motor 19, two matching fan sections 5 supported on a hub 23 and bushing 13 and driven by a lost motion pin and slot connection from the shutter 7 which is resiliently connected to the bushing 13 by a spring 8, and a second shutter 17 also resiliently connected by a spring to the bushing 13 and having a pin and slot driving connection with the fan sections. When rotating in one direction the fan supplies fresh air through one set of apertures and withdraws foul air through another set in which case one shutter has apertures 32 (Fig. 8) which coincide with apertures 26 in the fan rotor when the fan is rotating normally but which move relative to the rotor (because of the pin and slot connection) to close the apertures 26 when the fan slows down or stops. Similarly the apertures 25 in the fan rotor are controlled by the shutter 17. Only a single shutter may be employed in which case it controls all the apertures at one side of the fan and the fan rotor mßy be driven by the motor whilst the shutters are driven from the rotor. The shutters have fins 33 and a light baffle 6 is included. The fan may be adapted for one-way operation by providing a keyhole spring between each shutter and the fan rotor and having a pin and slot connection to limit relative movement between only one shutter and the rotor so that this shutter is open when the fan rotates in one direction but closed in the opposite direction whilst the other shutter since it can move through the full extent of the "keyhole" in both directions is open for both senses of rotation of the fan. Specification 872,472 is referred to.

Title: Improvements in or relating to time modulators for electric pulses

Filed: 1947-11-11
Abstract: 644,925. Pulse modulation. STANDARD TELEPHONES & CABLES, Ltd. Nov. 11, 1947, No. 29985. [Class 40 (v)] [Also in Group XL (a)] A circuit for producing time-modulated pulses comprises a cold cathode tube with two electrodes, a train of pulses being applied to one electrode, the modulating voltage being applied to vary the steady tube bias which is less than that necessary for maintaining a discharge. In the embodiment described, an unmodulated train of pulses is applied through condenser 15 to the anode 2 of tube 1, (see Group XL (a)), which is polarized from positive source 6, through resistance 5. The cathode 3 is connected through output transformer 8 and resistance 9 to a negative potential source 10, and the modulating voltage is applied through condenser 17 to the junction of the primary of 8 and resistance 9. An auxiliary cathode 4 may be provided to maintain a permanent discharge to the anode controlling the ionization level of the tube as described in Specification 639,827. When a pulse is applied to the anode, the gap 2, 3 breaks down, after a delay depending on the effective difference of potential between the electrodes and deionizes when the applied pulse ceases, as described in Specification 639,827. Duration modulated pulses thus appear at the output of transformer 8, which pulses may be differentiated by circuit 18, 19 to produce time modulated leading-edge pulses and negative trailing edge pulses which are eliminated by limiter 20.

Title: Improvements in or relating to the production of metal halides
Inventor: COOPER WILFRID
IPC: C01G23/02
Filed: 1959-09-02
Abstract: Metal halides, which volatalize at temperatures below the melting point of the parent metal, particularly aluminium and titanium iodides are prepared by contacting gaseous halogen with heated metal in an evacuated reaction vessel provided with a removable liner of the same metal or of a different metal that forms an inert coherent halide film in operation.  According to examples (i) a glass tube, fitted with an aluminium liner sealed to the glass with asbestos wool was filled with coarse aluminium and heated to 500 DEG -525 DEG C. under vacuum after which at 600 DEG C., iodine vapour was reacted to form the triiodide.  After several runs the liner was removed and pulverised to form a fresh charge of metal, (ii) a similar run was effected with a titanium lined metal to form, at 650 DEG C., titanium tetraiodide.  Reference is made to molybdenum fluorination using a copper liner and to the production of the halides of Al, Ti and Zr, tetrachlorides of V and Mo and to tungsten hexa-chloride and hexabromide.
