Title: Disc braking assembly
IPC: F16D65/14
Filed: 1975-02-27
Abstract: 1488611 Sliding caliper disc brakes; wear adjusting KELSEY-HAYES CO 27 Feb 1975 [28 Feb 1974] 8339/75 Heading F2E The mechanical activating mechanism for the fluid operated piston 23 of a sliding caliper disc brake comprises an axially movable activator 34 slidable in a bore 28 formed in the end wall 22 of cylinder bore 21 and having a reduced diameter portion 33 connected to the piston by an automatic wear adjusting mechanism 34, a rotary cam mechanism 47 disposed in a recess 29 in the caliper and a lever 57 for rotating mechanism 47 to cause axial movement of actuator 31 via balls 45, the recess 29 being formed in a portion of the caliper integral with wall 22. A seal 37 is interposed between actuator 31 and bore 28 and a lip seal 56 prevents the ingress of dirt to the cam mechanism while allowing fluid to escape in the event of failure of seal 37. The wear adjusting mechanism (Fig. 2) includes a housing 65, press-fitted into an adaptor 35 fixed to piston 23, a rotatable threaded member 66 having external threads 68 of relatively large pitch and internal threads 67 of relatively small pitch, the latter engaging threading on portion 33 of actuator 31. A drive ring 69 abuts end faces 72 of housing 68 and threadedly engages member 66; a ratchet member 75 is urged into contact with serrations 74 on the drive ring. In operation, admission of fluid in cylinder 21 moves piston 23 to the right and the caliper to the left but prevents axial movement of actuator 31 relative to the caliper. The adaptor 35 consequently urges housing 65, and consequently ring 69, to the right so causing member 66 to rotate by an amount depending on the differential screw action between its internal and external threads. If more than a predetermined degree of wear has occurred, the ratchet slips a tooth and member 66 undergoes less rotation on the return stroke than on its advance. Wear adjustment does not take place during mechanical actuation.

Title: Arrangement for controlling the brightness of electric lamps
IPC: H05B39/04
Filed: 1955-03-22
Abstract: 766,097. Dimming control systems for lamps. LICENTIA PATENT-VERWALTUNGS-GES. March 22, 1955 [March 25, 1954], No. 8361/55. Drawings to Specification. Class 38 (4). In a dimming system for incandescent, or discharge, lamps a subjective variation of brightness linearly related with the displacement of a control member, which is uniformly displaced with time, is obtained by means, actuated by the control member, which exerts a greater control on the lamp current when the control member is near its two end positions than when it is near the centre of its range of displacement. The control means may be a variable potentiometer the total resistance of which is high in relation to that of the load connected to its movable contact which is uniformly displaced by the control member. Alternatively, the control means may be a variable series resistor provided with suitably graded resistance steps. In other forms, control means having linear characteristics, such as a low-resistance variable potentiometer, a uniformly tapped series resistor, or a regulating transformer are employed, their moving members being moved non- uniformly by a suitably shaped cam driven by the uniformly displaced control member. Linear amplifiers, magnetic or electronic, may be inserted between the control means and the lamps.

Filed: 1949-03-29
Abstract: 665,153. Supersonic inspection devices. DUNLOP RUBBER CO., Ltd., POWELL, E. F., and HATFIELD, P. Class 118 (ii). [Also in Group XXXIX] Relates to a method of detecting flaws in tyre carcasses in which the intensity of a beam of continuous supersonic waves of frequency 55-75 kc/s transmitted through the carcass is measured, the presence of a flaw being indicated by a decrease in the intensity. The tyre is supported on two rollers 7 in a water bath 2, a piezo-electric quartz-crystal transmitter 10 being supported within the tyre by an adjustable mounting 11, 14 and two horizontally staggered horizontal rows of piezo-electric quartz-crystal receivers 16 are mounted transversely to the tyre on a trolly 18 mounted on a transverse U-shaped rail 20, each receiver being connected via a separate amplifier and rectifier to a deflection type meter. In operation the gain of the amplifiers is adjusted to give predetermined deflections on the meters and the tyre is then rotated manually or by driving one of the rollers 7 the presence of a flaw being indicated by a decreased meter deflection; the meters may also operate lamps when a large reduction in intensity, e.g. 50 per cent or 75 per cent occurs. Alternatively, the crystal receivers may be connected sequentially via a single amplifier to the Y plates of a cathode-ray tube the beam of which is synchronously displaced horizontally in steps so that the amplitudes of the resultant horizontally spaced vertical traces on the screen are proportional to the outputs from the receivers. When testing a large tyre, the transmitter crystal and the receiver trolly may be progressively moved across the tyre or alternatively a number of fixed sets of receiver crystals may be used. Transducers. A suitable form of watertight quartz crystal transducer, Fig. 3, comprises a brass cylindrical housing 31 open at one end and having a coaxial neck-portion 32 at the other end. The crystal unit 33 comprises alternate plates of steel and quartz, alternate steel plates being connected to the housing and the other intermediate steel plates being connected to a lead 34 which may be coupled to a coaxial cable at the neck. The crystal unit is spaced from the neck end of the housing by sponge rubber 35 and the neck is sealed with polyethylene 41. A rubber pad 37 is cemented to the face of the crystal unit and pressed into watertight contact with a brass washer 36 by a threaded annular brass cap 38. In an alternative construction, Fig. 4 (not shown), the cylindical housing is in two coaxial overlapping parts, the crystal unit being held in an inwardly extending flange in the smaller diameter part with the end steel plate exposed.
