Abstract: 1,054,875. Making electrodes. JOHNSON, MATTHEY & CO. Ltd. April 5, 1965 [April 9, 1964], No. 14702/64. Heading B3A. [Also in Division C7] In the manufacture of silver electrolytic anodes, silver of about 99À98% purity is melted under a carbon cover and stirred with a graphite rod to remove as far as possible any oxygen. The molten silver, at 1090‹ C., is poured into a continuous casting machine forming billets which are rapidly water quenched, cut to size and formed into electrodes. The electrodes are annealed in an inert atmosphere to effect homogenization of the crystals at temperature within the range of 400-950‹ C. for a period of 2-16 hours and cooled below 200‹ C., before being exposed in air and quenched in water. The electrodes are thus formed substantially free from oxygen and with homogeneous crystals thereby substantially reducing the tendency for coarse or fine powdered silver from falling away from the anode during plating operations &c. The electrodes may alternatively be formed by extrusion.

Abstract: 1,239,097. Frequency discriminators. SOC. NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION. 3 July, 1969 [4 July, 1968], No. 33542/69. Heading H3A. A frequency discriminator includes a filter circuit CR which is charged through a first field effect transistor Q1 and discharged through a second field effect transistor Q2, the two transistors being alternately switched on and off at the frequency being measured. Pulses at frequency F are applied at input E, and the leading edge of a pulse sets trigger circuit B to open switch I. Capacitor Cl then charges until the voltage across it is equal to a reference voltage U1 at the slider of potentiometer P1 At equality, comparator A produces an output pulse which resets trigger B to close switch I and discharge capacitor Cl. The cycle recommences at the next input pulse. Antiphase outputs of constant width pulses are thus obtained from trigger B on lines b to switch the transistors Q1, Q2. During the time Q1 is on capacitor C is charged from a constant voltage derived from Zener Z, so that the filter input consists of constant amplitude constant width pulses. As transistors Q1, Q2 are both subject to the same temperature conditions errors due to temperature variations are eliminated.

Abstract: 1,258,768. Shearing. WESTINGHOUSE ELECTRIC CORP. 31 Dec., 1968 [16 Jan., 1968], No. 61903/68. Heading B3W. [Also in Divisions G4-G6] A control system for a rolling mill having a shear 27 for cutting the strip being rolled, a measuring roll 36, pulse generator 64 and counter 66 providing an indication of the length of strip which has passed a given point and control means 58, having a store for an indication of the desired length of strip, which is adapted to actuate the shear when this length has passed the point. The purpose of the invention is to use the crop shear 27, which is provided between the roughing mill 16 and the finishing mill 26 for trimming the ends of the strip, also to divide the strip into smaller lengths as may be required for filling small orders. The leading edge of the strip, having been trimmed by the shears 27, enters the rolls of the first stand FS-1. A load cell 24 detects this and passes a signal via a counter initiating circuit 68 and computer 58 to start the counter. Measuring roll 36 drives a generator 64, the pulses being counted in counter 66, and a speed detector 37 which provides a signal to enable the crop shear control circuit compensate for the speed of movement of the strip. The speed and position of the crop shear rolls 29 are also signalled to circuit 60 so that they can be controlled to make the cut at the correct instant. The desired length is entered in the computer store by length control unit 70 or data input 72. When the counter 66 indicates that the length of strip equals the desired length, the shear control circuit 66 is operated and shear motor 30 is energized to cut the strip. After passing through the finishing stands FS-1 to FS-7 the finished strip is rolled up at 54.

Abstract: 1287941 Brake locking devices GIRLING Ltd 10 April 1970 [11 April 1969] 18764/69 Addition to 1245985 Heading F2E An internal shoe drum brake comprises a pair of arcuate brake shoes 42, 43, a pair of carriers 44, 46 one associated with each shoe for transmitting actuating forces to the respective shoe through the intermediary of a thrust member, an hydraulic slave cylinder 47 for power actuation of the carriers, a lock unit 10 comprising a strut 10 of adjustable length arranged to act between the two carriers and means for selectively locking the strut in an extended position to hold the carriers against retraction. There are resilient overload means, e.g. Bellville washers 31 or a coil or solid rubber spring, acting in series with the strut in the locked condition of the strut; the slave cylinder is operable through one carrier of a pivoted lever 51 to relieve the strut of the load imposed upon it by the resilient means in the locked condition of the strut. As shown, the lock unit 10 comprises a housing 11 receiving a shaft 12 which form two relatively movable parts and between which is a collettype clutch formed of a number of wedgedshaped elements 13 each having an internal friction lining 14 and co-operable with the frusto-conical clutch face 16 of the housing, the elements being biased into locking engagement with the face 16 by a spring 17. Release of the clutch is controlled by a fluid pressure actuated piston-cylinder device 19, 21 in the housing wherein the end of the piston normally abuts the clutch elements 13. The pre-loaded washers 31 are disposed between collars 28, 29 and the shaft 12 is connected at one end 22 to the carrier 44 and at the other end to the lever 51, while the end cap 26 of the unit is abutted by the carrier 46. In service brake actuation, the carrier 44 and shoe 42 are forced into engagement with the brake drum and lever 51, pivoted on the back plate 41, is rotated taking with it the shaft 12 this movement being transmitted by the washers 31 to end cap 26, carrier 46 and shoe 43; the carrier 42 carries therewith the housing 11. At this time, fluid pressure is applied to the piston-cylinder 19, 21 to hold the clutch disengaged, and to operate the unit to act as a parking brake. Fluid pressure is released, by manipulation of a control valve, from the cylinder 21 before releasing the actuator 47. If substantial contraction of the brake drum takes place upon cooling of an overheated condition, the service brake is operated to press lever 51 and shaft 12 and the housing in opposite directions. In modifications, (a) the lever 51 is pivoted to an adjustable shoe abutment which also forms the fulcrum for the carrier 46, (b) the carrier is pinned directly to the shaft connector 23 and the spring washers 31 are housed in and act between a pair of telescopically arranged housing parts between the carrier 46 and shoe 43.
