Title: Improvements relating to disc brakes
Inventor: DAVIS JOHN WALTER
IPC: F16D65/52
Filed: 1961-09-02
Abstract: 1,024,851. Disc brakes. DUNLOP RUBBER CO Ltd. Aug. 23, 1962 [Sept. 2, 1961], No. 31621/61. Heading F2E. A disc brake comprises a non-rotatable brake housing 10 having an abutment face 29 to resist circumferential movement of a friction element 19 in the plane of a rotatable disc 11 and means 22 for forcing the element into frictional engagement with the disc. The friction element, Fig. 4 (not shown), has a shape which is produced when one radial end of a segment is cut off and positioned so that the erst-while radial edges abut. As shown, the pads 19 are forced against the disc by pressure members 14, 15, which are pivoted at 16 to the housing 10 and extend at a slight angle to each other. Convex protrusions 17 on the members 14, 15 bear on the backing plate 18. The pressure members are actuated by a pistoncylinder mechanism 22, a pivoted lever 21 and a tie-rod 20 having an automatic adjuster 26. A pair of springy but deformable fingers 34, the ends of which are engaged in holes 35 in the members 14, 15 are provided to retract the members 14, 15 after each brake application but are capable of being progressively deformed as wear of the pads 19 takes place. Springs 36 between the backing plate 18 and the fingers 34 retract the pads. Tongues 27, Fig. 2 (not shown), on, and bent at right-angles to the backing plates, which tongues are a slidable fit in a slot 33 in a keep member 32, and projections 30 on the backing plates engaged in recesses 32, retain the trailing edge 28 of the pad in abutting relationship with the face 29. A measure of damping which tends to eliminate brake squeal is provided due to the contact of the friction material itself with the abutment face. The lever 21 may be actuated by mechanical as well as by, or alternatively to, the pistoncylinder mechanism 22. Alternatively, hydraulic piston-cylinder assemblies on each side of the disc may be provided to actuate the pads. Other shapes of pads are described wherein the trailing abutting edge is arcuate having the centroid of the friction element as its centre.

Filed: 1923-12-17
Abstract: 226,960. British Thomson-Houston Co., Ltd., and Jewitt, D. E. Dec. 17, 1923. Driving-arrangements for screw propellers.- A direct current systern of electric propulsion for multiple screw ships comprises a single power supply and propeller motors in a series circuit in which a full load current is maintained automatically under manoeuvring conditions. Two propeller motors 1 are in the circuit 3 with a generator 2. The field 4 of each motor is excited from a supply 5 provided with a reversing potentiometer type rheostat 6. These rheostats are operated by a motor and protected by apparatus described in Specification 202,117. The field 7 of the generator is also excited from the circuit 3 and is provided with a rheostat 8 operated by a motor 10 controlled bv a relay 9 in the main circuit 3. Instead of the motor, a solenoid or equivalent controlling device may be used. The relay automatically maintains a full load current in the series system, a tendency to a rise or fall in the current resulting in the relay putting the motor 10 in action to control the rheostat 8 and thus reduce or increase the field 7 and consequently the generator voltage.

Title: Improvements relating to water-soluble quaternised colour salts of triazene compounds and their use
IPC: C09B35/00
Filed: 1963-08-14
Abstract: The invention comprises water-soluble quaternary colour salts of triazene compounds of the formula <FORM:1019113/C4-C5/1> wherein A represents an aryl radical which may contain substituents which do not dissociate acid in water, B represents an arylene radical which may contain substituents which do not dissociate acid in water, X represents a divalent radical which completes the nitrogen-containing ring to a five or six-membered ring, R and R1 independently of each other represent a low alkyl radical, Y represents an anion and n represents 0 or 1.  Such salts are prepared by (a) coupling the diazonium compound of an amine of the formula A-N=N-B-NH2 with a compound of the formula <FORM:1019113/C4-C5/2> to form a compound of the formula <FORM:1019113/C4-C5/3> and reacting the latter with an ester of a low alkanol to obtain the desired colour salt or (b) reacting a diazoimino compound of the formula <FORM:1019113/C4-C5/4> with an ester of a low alkanol in the presence of alkalie to form a compound of the formula <FORM:1019113/C4-C5/5> and coverting the latter with further ester into the desired colour salt or (c) converting a compound of the formula <FORM:1019113/C4-C5/6> with an ester of a low alkanol to a compound of the formula <FORM:1019113/C4-C5/7> into the desired colour salt.  In an example an orange colour salt is obtained by coupling diazotized 4-aminoazobenzene with 2,3-dihydro-2 - imino - 3 - methyl - 6 - methoxy - benzthiazole, treating the product with dimethyl sulphate and isolating the product as a zinc chloride double salt.  Additional examples relate to the preparation of colour salts in which the heterocyclic moieties are derived from such compounds as 2-amino-3-ethyl-6-methoxy-benz-thiazolium chloride, 2 - amino - 3 - methyl-thiazolium methosulphate, 1,2 - dihydro - 1-methyl - 2 - iminopyridine and 1,2 - dihydro-1-imino - 2 - methyl - isoquinoline. Many additional starting materials are specified.  The colour salts are particularly suitable for dyeing or printing polymeric and copolymeric polyacrylonitrile fibres.

Abstract: 1,240,585. Winches. INDUSTREELE HANDELSCOMBINATIE HOLLAND N.V. 26 June, 1969, No. 32449/69. Heading B8B. A device for the control of shift movements of a floating body which may be shifted by a hauling winch while being braked by the consequential paying-out of a veering winch, comprises a throttle valve 11 in the feed circuit 6 for the veering winch motor 1, to control the braking action of the veering winch dependent on the load of the hauling winch below a certain value, the braking action being increased when the load on the hauling winch is decreased and vice versa whereby the winch cables attached to the body are maintained taut. The throttle valve 11 is spring-biased into a closed position and is opened by fluid pressure in a conduit 21 which is supplied through a selective valve 22 either from a branch 17 of the hauling winch circuit or from the branch 7 of the veering winch circuit, whichever has the higher pressure. As shown, the hauling winch motor 2 is pressurized through the branch 17 and through a pair of non-return valves which by-pass a throttle valve 20 and a pressure control valve 19, while a closed circuit is maintained for the veering winch motor 1 by a control valve 5. During hauling by the motor 2, the opening of the throttle valve 11 is controlled in proportion to the load on the motor 2 and hence the pressure in the fluid supply branch 17, the valve 11 being by-passed by a safety valve 28 limiting the maximum braking force, and a minimum braking force being assured by a pressure control valve 8. When the motor 1 is to be driven in the winch paying-out direction, a branch 7 becomes the high-pressure line, via the control vavle 5 and the throttle valve 11 is maintained open by pressure from the branch 7 via the valve 22. If the motor 1 is to be used for hauling, the valves 20, 19, 25 fulfil the same functions as the previously described valves 11, 8, 22, the valves 11 and 8 being by-passed by non-return valves 13 and 10.

Abstract: 675,369. Treating liquids in a magnetic field. VERMEIREN, T. I. S. Dec. 21, 1949 [Dec. 24, 1948; Dec. 6, 1949] , Nos. 32704/49 and 32705/49. Classes 49. [Also in Groups I, XVIII and XXXV] Sugar juices, milk, or the like, are treated in a device provided with means for producing a magnetic field and a passage for the liquid to be treated comprising a number of magnetic elements, the passage being arranged in such a way that the lines of liquid flow cut successively in a substantially perpendicular manner the lines of force of the magnetic fields corresponding to the magnetic elements. In one form a pipe 1, Fig. 1, along which the water or other liquid passes in the direction 7 is arranged along the common axis of four solenoids 4 having like poles adjacent and has supported within it by members 3, Fig. 2, made from non- magnetic material a rod 2 of high magnetic permeability. The nature of the resulting magnetic field is indicated by lines of force 8, those in adjacent planes being opposite in sense. The solenoids 4 are energised by either alternating or direct current. They may be replaced by ring-shaped permanent magnets which alternatively may be arranged within the pipe 1. The poles are located at the ends of the rings in planes perpendicular to the ring axes, like poles being adjacent as before. In Fig. 6 numbers of permanent bar magnets 4 are arranged in columns the members of each column interlocking and having similar like poles adjacent. Each pole of each magnet in one column is opposite a pole of opposite sign in adjacent columns. The poles are disposed along the longer edges of the bars. Lines of force are shown at 8 and lines of liquid flow at 7. Where interlocking means are not provided the bars are supported by vertically-grooved end-plates. In Figs. 9 and 10 each magnet comprises a bar 10 of arcuate section, four such bars constituting a pipe-like structure. The poles are again disposed along the longer edges of the bars and like poles are adjacent. The liquid is made to flow, along a pipe 1 disposed within the magnets 10, in a helicoidal path by an Archimedean screw having an axis 12 of high magnetic permeability. The magnets are supported by rings 14. Lines of force are shown at 15, Fig. 10. Alternatively the pipe 1 may be outside the magnets, these members all being supported in grooved circular end plates which also have flanged central holes for the passage of the liquid. It is stated that the treated liquids do not give rise to calcareous or other incrustations and are effective in dislodging such deposits from encrusted apparatus. Specification 625,732 (see Groups I and XVIII) is referred to.
