Abstract: 1,172,580. Self-adjusting disc brakes. KELSEY-HAYES CO. 20 July, 1967 [22 Aug., 1966], No. 33501/67. Heading F2E. The return movement of the piston of a fluid pressure operated disc brake of the reaction type is limited by a cage of balls co-operating with a conical surface. In Fig. 4, pressure is applied to friction pad 35 either by a fluid operated piston 47 or by a plunger 49 through linkwork 65, 59, 73, 67. The plunger is locked to the piston for movement of the plunger in the brake applying direction by balls 54 held in a cage 52 but if there is any slack due to wear, fluid pressure will advance the piston and a spring 53 will move the cage to a larger diameter portion of the plunger and thus prevent appreciable return of the piston. The brake caliper is pivoted at two axes by bolts 31 and 32 (Figs. 1 and 2, not shown). The friction pads are provided with end flanges 38 (Fig. 1, not shown) which loosely engage in slots which are covered by plates 44 (Fig. 2, not shown).

Title: Improvements in or relating to methods of and apparatus for, determining the stretchof elastic materials
IPC: G01N3/08
Filed: 1957-11-01
Abstract: 849,694. Testing physical qualities of materials. DI PIERI, C., and S.I.A.T.E.M. SOC. ITALIAN APPARECCHI TERMO-ELECTRO-MECCANICI S.P.A. Nov. 1, 1957 [Nov. 21, 1956], No. 34207/57. Class 106 (2). A method and apparatus for determining the multi-directional stress of a foil or sheet of elastic material by measuring its extension. in at least one direction comprises securing the foil or sheet against displacement along a line defining the boundary of a portion of the test piece and displacing an inner zone of the portion to a position in which it lies in a plane displaced from the plane containing its boundary. As shown, the test sheet M, which is either circular or polygonal, is held by an annular or polygonal clamp B, and a sheath G of a flexible but non- elastic material is held in a similar clamp A 1 . The sheath G may be a wire fabric, a hose of knitted textile fibres or a row of parallel wires or bands. Fig. 7 shows the initial position, in which the sheet M is taut and the sheath G lies over a ring A to which a force F can be applied by the framework shown. When the force F is applied, the sheet M tends to adhere to the sheath G and so the central portion only, bounded by the ring A, is stretched and the forces acting on it are substantially coplanar and concurrent. To determine these forces, an additional known force F 1  is applied to the centre of the sheet M when in the position shown in Fig. 8 and from the displacement of the centre of the sheet, the forces acting on it can be calculated. As described, the force F is applied by a reciprocating motor, and the force F 1  by a lever carrying a weight, movement of which lever over an arcuate scale is indicated. The test is carried out in a chamber the temperature of which is thermostatically controlled. Hot air may be circulated by a blower or a radiant heater may be used to maintain the temperature.

Title: Improvements in or relating to the manufacture of Pneumatic Tyres
Inventor: GRAY DEREK JOHN
IPC: B29D30/00
Filed: 1966-07-30
Abstract: 1,190,748. Moulding tyres. DUNLOP CO. Ltd. 27 July, 1967 [30 July, 1966], No. 34327/66. Heading B5A. [Also in Division G3] In the shaping of an unvulcanized tyre within a press of the kind having relatively movable opposed closing elements and an inflatable shaping bag, the elements are brought together at a programmed rate and the tyre is radially expanded between its bead regions at a programmed rate, the rates being mutually synchronized. The two rates are continuously sensed to detect any variation in them and a correction is applied, if necessary, to maintain them. A press comprises two pairs of opposed mould halves 24, 25, 24a, 25a and shaping bags 15, 14; the mould halves are brought together by a motor 1, and the bags are supplied with high pressure steam from a source S and via valves 10, 17. The control system includes a synchronous electric motor 2 with cams 3, 4 on its shaft; the cam 3 controls the movement of a follower engaging a potentiometer 5 which controls a signal fed to an amplifier 21 controlling the speed of motor 1; similarly the cam 4 controls via a potentiometer 6 the signals to amplifiers 11 and 19 controlling via electropneumatic converters 9 and 18, the operation of the steam valves 10, 17. The radial expansion of the tyre is sensed by pivoting arms 22, 23 operably connected to rotary potentiometers varying a voltage tapped to amplifiers 11 and 19 to thereby control the steam valve operation. A press closure sensing device 16, including a sensing arm, not shown, is coupled to a rotary potentiometer and controls a voltage supplied to amplifier 21 to control the speed of motor 1. In an embodiment where a press closure sensing device is not provided, the motor driving the closure members is controlled by a castellated cam on the cam shaft operating a microswitch, and a similar cam and microswitch on the press, the switches controlling the motor supply. Photo-electric devices may replace the sensing arms, being actuable by the movement of the radially outer surface of the tyre and the movement of the press elements. Instead of a cam and potentiometer being used with a main amplifier, an electronically-generated input signal may be fed to the amplifier and produced from an electronic amplifier; the modified output signal from the main amplifier is then fed to an electro-pneumatic converter to vary the inflation-fluid flow valve.

Title: A method of producing time compression of a signal
Inventor: HOBSON ALBERT
IPC: G01R23/00
Filed: 1960-10-08
Abstract: 929,891. Frequency analysis. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Sept. 27, 1961 [Oct. 8, 1960], No. 34552/60. Class 37. [Also in Groups XXXVIII, XXXIX, XL (a) and XL (b)] In a method of producing time compression of a periodic signal the signal waveform is displayed on the face A of a storage tube C.R.O. and an image of the trace is focused on the photo-sensitive face C of an image converter tube. The resulting electrons are focused by plates D on to fluorescent screen E and by applying a sawtooth bias to plates D the image is made to move across the screen E and this moving image is focused on slit F so that the image is scanned across the slit at the frequency of the sawtooth wave applied to the plates D. The vertical position of the image at the slit F will vary in the same way as the amplitude of the original signal varied but at a rate dependent on the rate the image is traversing the slit. The vertical position of the image is converted to a variation in signal level by interposing between the slit and a photo-cell H an optically graded wedge G having a linear change in density along its length (i.e. Y axis). The output of the photo-cell thus reproduces the transducer output on a time compressed scale if the frequency of the sawtooth wave is higher than the repetition frequency of the signal waveform. It is suggested that the system is applicable to correlation studies, or that it might be used for frequency analysis by feeding the output to a variable frequency filter, or alternatively the scanning frequency applied to plates D could be varied and a fixed frequency filter used. It is also suggested that the components of the system might be combined in one unit by the design of a suitable tube.

Title: Improvements in and relating to the dry moulding of ceramic materials
IPC: C04B33/20
Filed: 1930-11-18
Abstract: Heavy metal soaps and other compounds of metals with organic bodies are used to confer mouldability on ceramic materials when they are dry moulded, before firing.  The addition of the dry mouldable materials to the ceramic substances may be made by dry admixture or by precipitation in a liquid suspension of the ceramic material, by interaction of a metallic and an organic compound followed by drying and dry moulding.  In examples the non-mouldable material consists of an aqueous suspension of (a) porcelain material or (b) aluminium oxide.  An insoluble aluminium salt of a high molecular fatty acid is precipitated in the suspension, and the mixture dried.  On firing in (a) aluminium silicate is produced while in (b) aluminium oxide is produced so that the whole body is composed of aluminium oxide.  In a further example a glaze mixture of lime, silicic acid, felspar, and lead oxide is dry moulded as above and sintered at temperatures below 1000 DEG  C.  The Specification as open to inspection under Sect. 91 (3) (a) comprises also the use of galalith, artificial resin, and the like as materials conferring mouldability, and of gypsum, plaster or cement in place of the ceramic material, these not being fixed, but after moulding hardened in the usual manner.  This subject-matter does not appear in the Specification as accepted.
