Title: Improvements in or relating to fluid brakes
IPC: F16D57/06
Filed: 1925-03-09
Abstract: 244,961. Beck, J. C. March 9, 1925. Fluid friction.-A braking device comprises iutermeshing gear wheels arranged to circulate liquid in a casing and means whereby the passage for the liquid adjacent the engaging teeth can be more or less restricted either by moving a part towards or from the engaging teeth or by moving the wheel or wheels. As shown in Fig. 1, the gear wheel on the driven shaft 21 to be braked meshes with gear wheels 18, 20 mounted on eccentric bearings 24, 26 which can be adjusted by arms 29, 30 and a link 31 to adjust the extent to which the teeth of the wheels mesh and also the clearance between the driven whels 18, 20 and the cylindrical walls of the casing at the parts 33. With the wheels only slightly in mesh and the clearance from the parts 33 of the casing relatively great there is no braking action, but if the wheels 18, 20 are brought closer to the wheel 19, the liquid is forced out from between the teeth as these come into engagement and by reason of the restricted clearance between the teeth and the parts 33 of the casing is unable to flow back freely. thus producing a braking resistance which may in the extreme position of adjustment of the wheels be sufficient to lock them. In another arrangement, Fig. 4, the wheel 42 is mounted in a slidable block 41 provided with side plates 39 which fit closely against the faces of the wheels 42, 44. By turning an eccentric 47 the wheel 42 may thus be brought, as shown, into close mesh with the wheel 44 and at the same time the clearance between the curved surfaces 46 of the block and the teeth of the wheel 44 is reduced so as to produce the braking action. The arrangement of the eccentric is such that it may yield under excessive reaction of the braking resistance. Fig. 7, shows an arrangement in which the gear wheels 54, 55 are permanently closely meshed and in which a plate 59 can be moved towards the gear wheel 54 by a screw 60 so as to restrict the passage across the face of this wheel by which the fluid expelled from between the teeth of the wheels must flow, In a further form in which also the wheels are permanently in close mesh, a pair of blocks corresponding to the parts 33, Fig. 1, of the casing adjacent the intermeshing parts of the wheels are arranged to be moved towards or away from the teeth of the wheels in a direction at right angles to the line of centres of the wheels to control the braking action. A pressure gauge may be provided to indicate the pressure within the housing.

Title: Disc brake and a friction pad for such a disc brake
IPC: F16D55/224
Filed: 1974-02-13
Abstract: 1416122 Spot-type disc brakes SOC ANON DBA 13 Feb 1974 [8 March 1973] 06489/74 Heading F2E A disc brake comprises a caliper 32 axially slidable on two columns 16 attached to a fixed support 10 and including at least one brake actuator, e.g. 48 so as to urge on to the disc (not shown) two friction pads 50, 58, situated on opposite sides of the disc, the friction pads anchoring on the columns during braking, wherein the caliper is slidable on parts of the column surfaces facing out of the brake, and the pads are anchored on other parts of the column surfaces facing into the brake, connecting means being provided to prevent the caliper 32 from escaping radially outwards and the pads from being drawn radially inwards of the brake. As shown, each brake pad backing plate 52 or 60 has at opposite ends a concave cylindrical surface of revolution 62 subtending an angle of less than 180 degrees so that each brake pad may be introduced upwardly to bear against a part of the surface, facing radially inwardly, of the larger-diameter portion 20 of each of the two columns 16. Each column 16 is secured by a nut 28 in one arm 12 of the support plate 10 and has a smaller-diameter portion 24. The space between the arms is available to accommodate the hydraulic-actuator part 46 of the slidable caliper 32 which also has two projections 34 each having an under-surface 40 located on a part of the surface, facing radially outwardly, of a larger-diameter portion 20 of one of the columns 16. A pin 70 inserted through an outer lug 68 on the left-hand side of the caliper, then through lugs 64-one on each of backing plates 60 and 52-and finally through an inner lug 68 on the caliper, serves to hold the brake pads up and the caliper down. A noise-reducing spring 72 having its ends located beneath pin 70 is accommodated in an opening 66. As described, this arrangement is repeated on the right-hand side of the assembly. The "actuator" end of the caliper has a pair of projections 36 each having a part-cylindrical surface 44, Fig. 4, co-operating with a sleeve 38 of synthetic resilient material pushed on to the end 24 of one of the columns 16. Mutual retention for caliper and sleeve is provided by a resilient pin 76 one end of which penetrates a bore 74 communicating with surface 44, and the other end of which is located in a groove 42 in the sleeve. For dismantling, pins 76 are first withdrawn, then sleeves 38 are removed, releasing the "actuator" end of the caliper for subsequent upward movement; pins 70 are now withdrawn, after which the caliper may be removed upwardly and the brake pads downwardly. The hydraulic actuator need contain only one piston instead of the two (one only shown) of Fig. 1, and only one brake-pad-supporting pin 70 need be provided.

Title: Improvements in and relating to electric motor controllers
IPC: H02P1/16
Filed: 1930-02-27
Abstract: 338,087. Date, W. E. April 17, 1929, [Convention date]. Controllers, with combinations of resistances. - The resistances used for controlling a printing press motor during starting and while running are sc arranged that the heat generated is reduced and may be conveniently dissipated. The motor is started by depressing a press button 4, which energizes a coil 1<a> and closes switches 1<b> and 1<c> which, maintaining themselves closed, place the motor across the mains with parallel resistances R1 and R2 in series with the armature A. According to the invention the resistance R2 is replaced by a variable resistance R3 as soon as the back e.m.f. generated by the motor is sufficient to energize the coil 3a and close the switches 3c and 3b, the closing of the switch 3c resulting in the energization of a coil 2a and the consequent opening of a switch 2b. Thus the motor runs with parallel resistances R1 and R3 in series with the armature, and its speed is varied by adjusting the resistance, R3.

Filed: 1975-12-11
Abstract: 1512702 Controlling light RANK ORGANISATION Ltd 11 Dec 1975 [19 Feb 1975] 6968/75 Heading G2F [Also in Divisions G5 and H4]  A pair of inter-digitated electrodes is provided on each of two parallel opposed walls of a nematic liquid crystal cell whereby fields can be applied parallel to each wall to promote homogeneous alignment or, by connecting each pair of electrodes in common, a field can be applied perpendicular to the wall to promote homotropic alignment. The electrode fingers of one pair are inclined, e.g. at 90 degrees, to those of the other pair so that the resulting homogeneous alignments are nonparallel, giving a twisted nematic structure with optical rotary power. Such a cell disposed together with a retardation plate between polarizers provides a switchable colour filter e.g. for use with a monochrome cathode ray tube for a frame sequential colour display, but switching time must be less than frame flyback time. Selective switching of different areas of the cell is effected by using a plurality of pairs of inter-digitated electrodes, for example to provide a number of bands and to reduce the required switching speed in the abovementioned colour display, or to provide a coincidence addressed X-Y matrix or alphanumeric display device.
