Title: Improvements in or relating to disc brakes
Inventor: BURNETT RICHARD THOMAS
IPC: F16D65/54
Filed: 1968-08-08
Abstract: 1,237,775. Disc brakes. BENDIX CORP. 8 Aug., 1968, No. 37901/68. Heading F2E. In a floating-caliper disc brake a torque taking member 12 is located at one side of the brake disc 14 and has two circumferentially spaced arms 24, 26, a caliper housing 28 straddles the disc and is provided with sliding elements or pins 58 mounted for sliding movement on a respective one of the two circumferentially spaced arms 24, 26 such that each of the pins 58 comprises a sliding element slidingly arranged with respect to both the housing 28 and one spaced arm 24 or 26, the pins being provided with at least one abutment element 70, 72 to limit the amount of sliding movement of the caliper housing with respect to the pins 58 and reposition the caliper housing transversely to the brake disc faces to compensate for wear of the friction pad assemblies of the brake. As shown in Fig. 2, one friction pad assembly 45 is located by means of a spigot member 46 in a hole in one leg of the caliper housing 28 and the other friction pad assembly 52 is adapted to be urged against one face of the disc by means of an hydraulic piston and cylinder assembly 32 so that the reaction on the caliper housing urges the other friction pad assembly 45 into engagement with the opposite face of the brake disc. Anti-rattle springs 80, 84 are provided to urge the pins 58 into engagement with the respective circumferentially spaced arms 24, 26 of the torque taking member 12. The abutment elements 70, 72 are formed by C-washers which are engaged in recesses in the pins 58 so that a clearance A<SP>1</SP>B<SP>1</SP> and A<SP>1</SP>C<SP>1</SP> is provided between the washers 70 and the adjacent faces of the caliper housing 28 to provide the requisite brake clearance and compensate for wear of the friction pad assembly 45 to keep the pedal travel at a minimum at all times. Wear of the friction pad assembly 52 is compensated for by providing a frictional contact force between the seal 36 and the piston 34 such that upon release of the pressure from the chamber 40 the seal 36, which has been stressed in the groove 38 by the piston as it moves to the left, will return the piston to the right by a slight amount due to the return of the seal 36 to its unstressed condition. In an alternative embodiment (Fig. 5, not shown) the torque taking member is J-shaped in construction so as to provide for additional guiding of the pin (112). It is stated that the invention attempts to solve both rattle and " knock-back " problems.

Title: Improvements in d.c. excitation control arrangements for dynamic braking of electricmotors
Inventor: KWASNICA ADAM WAWRZYNIEC ANTON
Filed: 1956-12-19
Abstract: 873,366. Automatic control systems. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. March 13, 1958 [Dec. 19, 1956], No. 38753/56. Class 38 (4). [Also in Group XXXVII] An induction motor is braked by applying direct current, derived from a magnetic power amplifier and rectifier 6, to points 3 and 4 in its stator windings. A portion 4, 7 of the windings does not carry the excitation current, and is connected with an auxiliary A.C. source of substantially constant voltage in series with rectifier 8 and control winding 11 of a magnetic amplifier 12 which controls the power amplifier 6. For maintaining the excitation flux at a predetermined value, the winding 11 opposes a reference winding 13 which is connected in series with rectifier 14 and rheostat 15. A small increase of stator flux produces a change in the permeability of the core material, thereby causing a reduction of the impedance of the winding portion 4, 7. The resultant increase of the current passing through control winding 11 reduces the outputs of the amplifiers 6 and 12, whereby the stator flux is returned to the value determined by the setting of rheostat 15. A similar operation takes place if the stator flux tends to decrease.

Title: Improvements in and relating to the manufacture of transistors
IPC: H01L21/288
Filed: 1960-11-14
Abstract: 966,545. Semi-conductor devices. PHILCO CORPORATION. Nov. 14, 1960 [Nov. 12, 1959], No. 38997/60. Heading H1K. During the manufacture of known microalloy transistors, indium electrodes are plated on to germanium blanks by directing a stream of indium salt against the blank and passing an electric current through the stream to the surface, and a connecting whisker is soldered to the electrode by means of an indium soldering alloy containing gallium at the same time as the electrode is alloyed with the germanium. According to the invention, adverse effects of the gallium (such as weakening of the whisker and electrode and balling-up of the electrode) are reduced by including a small amount of effective iron in the indium plating solution. The iron should be in quantities small enough not to affect the operation of the transistor unduly. Where the plated electrode diameter is within 4 to 7 mils, the iron content is within 0.3 to 0.5 parts per million, but larger quantities of iron may be present if the quantity of effective iron is maintained small by the use of a complexing agent. Specifications 826,063, 847,628 and 894,708 are referred to.

Title: Improvements in and relating to electrical apparatus for comparing numerical data
IPC: G06F7/02
Filed: 1961-11-06
Abstract: 981,914. Comparing digital data. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 6, 1961 [Nov. 4, 1960], No. 39593/61. Headings G4A and G4M. The difference between two numbers is found and it is determined if the difference is less than a predetermined integral non-zero power of the radix of the number system employed (e.g. 10,100 &c. in decimal) by (1) setting a trigger 31 if all digits of the difference occupying orders greater than or equal to the highest order of the predetermined limit are zero, or by (2) setting a trigger 30 if all digits of the difference occupying orders greater than or equal to the highest order of the predetermined limit are equal to the radix less one. In the apparatus shown two five-digit binarycoded decimal numbers are subtracted serially by bit and digit in a device 11, not described, which gives true and complement outputs representing sum (S) and carry (C) bits. In the 1, 2, 4, 8-code used the following expressions indicate the bits necessary that a 0 or 9 should be the result of a digit subtraction (1 = S 1  bit, C 8  = carry at 8-bit time &c.): 0 exists when the result is #1. #8 (#4.#2. C 8  + 4.2.#C 8 ) 9 exists when the result is 1. 8 (#4.#2.C 8  + 4.2.#C 8 ). It is assumed that the limit is 100. The output of the subtractor is only sampled at the third to fifth digit (D) times. Triggers 30 and 31 are set at the beginning of the first digit time and are subsequently unset should the conditions set out above not exist. Triggers T 2  and T 4  store 2, 4 bits respectively and the outputs are applied to and gates 20 to 23. If at 8-bit time the expression within the brackets above is not true, or circuit 24 is up, and and circuit 25 operates to reset both triggers 30 and 31. If there is a true sum bit at 1- or 8-bit time the digit cannot be zero and trigger 31 is reset by and gate 27. If there is a complement sum bit at 1- or 8-bit time trigger 30 is reset by and gate 29. If either of these triggers is set at the end of D 5  a trigger 48 is set to indicate that the difference is within the predetermined limit. The apparatus by means of triggers 40 and 44 also indicates whether the subtrahend is greater or less than or equal to the minuend.
