Title: A process for the manufacture of coked briquettes suitable for metallurgical purposes from non-coking sub-bituminous or lignitous coals
IPC: C10L5/04
Filed: 1952-09-12
Abstract: 717,393. Briquettes. DONNELLY. R. P.. and BROADBENT, R. Sept. 12, 1952 [Sept. 17, 1951]. No. 22994/52. Classes 55 (1) and 55 (2) Briquettes suitable for metallurgical purposes are made from non-coking sub-bituminous or lignitous coals by first heating such coals to 800‹ C. or to such a temperature that the volatile matter is reduced to less than 2 per cent and then mixing the product with a binder and carbonizing the thus formed briquettes at about 600‹ C. Suitable binders are pitch and tar used in proportions of 5-20 per cent. The coals used may be selected or pretreated with solvents to have a low iron content.
Patent GB-785539-A (GB)
Title: Improvements in and relating to earth leakage detection and/or indication systems
IPC: G01R27/18
Filed: 1952-09-12
Abstract: 785,539. Protective arrangements. SIEMENS & GENERAL ELECTRIC RAILWAY SIGNAL CO., Ltd., AUSTIN, T. D., and RIDDLE, H. J. N. Nov. 2, 1953 [Sept. 12, 1952], No. 23029/52. Class 38 (5). In an earth leakage detection or indication arrangement for a supply system in which no conductor is normally earthed, a condenser is cyclically connected firstly so that it is charged in the event of an earth leakage from an associated supply conductor and secondly so that the charge is supplied to a detection or indication means. In the D.C. arrangement of Fig. 1, when changeover contacts IT1 are in one position, the condenser Q is connected between the positive conductor B and earth and is charged should an earth leakage from the negative conductor N exist. When the contacts IT1 are in the other position, the condenser Q discharges through the winding RW2 of a relay R and the flux produced is in opposition to that of a winding RW1 of the relay R. The relay R closes contacts R1 in circuit with a signal lamp S or other alarm means. The value of a resistance HR in series with the winding RW1 is such that the relay R is normally held operated with the contacts R1 open in the absence of earth leakage, but once the relay has been released the resistance HR must be shorted to reset the relay. The contacts IT1 are cyclically operated by means of an iterative relay circuit including a relay having windings ITW1, ITW2 and contacts IT2 in addition to the contacts IT1. When the contacts IT2 are closed, current initially flows through both relay windings which oppose one another, but as the charging of a condenser QR proceeds the current in ITW2 is reduced until the winding ITW1 predominates and the relay operates to open the contacts IT2 and change over the contacts IT1. The condenser QR now discharges through both windings ITW1, ITW2 to maintain the relay operated for a short period at the end of which the relay releases, the contacts IT2 close and the cycle is repeated. In the A.C. arrangement of Fig. 3, the condenser Q is charged by the leakage current through a transformer TF1, the secondary current of which is rectified at GR. The charging of the condenser Q by permanent capacitive currents (as distinct from resistive earth leakage currents) is prevented by a second transformer TF2 in series with a variable capacitor GB which is adjusted so that normally no resultant voltage exists across the secondaries of the transformers TF1 and TF2. In modified arrangements a detection circuit is associated with each conductor of the A.C. or D.C. supply, the circuits being controlled by a common iterative relay, Figs. 2 and 4 (not shown).

Title: Improvements in or relating to spring clutch mechanism

Abstract: 780,140. Friction clutches. MARQUETTE METAL PRODUCTS CO. Aug. 10, 1955, No. 23067/55. Class 80 (2). Overrun of an output shaft S, driven by an input pulley 1 through a coil-spring clutch 5, capable of transmitting substantial torque in one direction only, is prevented above a predetermined speed by centrifugal means, such as pawls 20, Figs. 1 and 2, pivoted on an output-mounted hub 2, and centrifugally engaged, against spring force 24, with notches 22 in the input pulley 1; or alternatively an oppositely-wound auxiliary coil-spring clutch 30, Fig. 4, fast at one end to the output hub 2, and having its other free end, slotted at 35 for flexibility, expanded centrifugally into clutch engagement with the input pulley 1. In Figs. 1 and 2, the main clutch-spring 5 is anchored to a part 6 of the input pulley 1 by an internal split ring 7 which expands the outer end of the spring as an interference fit in the part 6. The free inner end of the spring 5 is expanded into clutch engagement with the inner surface 4a of a pocket in the output hub 2 by manually retracting a control part 12, permitting springs 11 to move axially to the right a sleeve 9, slidably pinned at 10 to the output hub 2, and having an axial projection 9a which moves into the path of the end coil of the spring 5 to expand the latter. To ensure that, when overrun tends to occur above the predetermined speed, the pawls 20 will exactly register with the notches 22, the rim 16 of the pulley 1, carrying the notches 22, is circumferentially adjustable to any angle relative to the pulley-part 6, by axial bolts 18 passing through arcuate slots in the part 6 and screwing into one or other of two series of holes 19 in the rim 16, the bolts 18 being tightened whilst the coil-spring 5 is manually held in torque transmitting condition with the pawls in correct register. The shaft 2 drives a twocylinder gas compressor from the fan-drive of a vehicle engine.
