Title: Improvements in or relating to circuit arrangements for disconnecting a load from a direct current supply system
IPC: H01H9/32
Filed: 1961-09-29
Abstract: 979,458. Semi-conductor thyratron switching circuits. SIEMENS-SCHUCKERTWERKE A.G. Sept. 29, 1961 [Dec. 14, 1960], No. 35394/61. Heading H3T. [Also in Division H2] An arrangement for disconnecting a load 17 from a D.C. supply system 13, 14 comprises a semi-conductor thyratron 16 and a disconnecting relay 15 which is operable only when the thyratron is non-conducting. To switch on the load, a control switch 19 is brought into the position shown to cause the charging of capacitors 21, 25 in striking and quenching circuits 20, 24, and to energize the coil 18 of the relay 15. The relay, with a delay, closes main contacts 7, 9 in the load circuit, and auxiliary contacts 11 to permit the capacitor 21 to provide a striking impulse through a transformer 23 to the thyratron to render it conducting. To switch off the load, the control switch 19 is operated to its other position to open contacts 1, 3 so that the coil 18 remains connected only in parallel with the load 17, and to close contacts 5 so that the capacitor 25 supplies a quenching pulse to the thyratron 16 through a transformer 27. The thyratron ceases to conduct, the coil 18 is de-energized and the relay 15 opens its contacts. The switch 19 may be a relay and have its contacts connected to an independent constant voltage source. The transformers 23 and 27 may be omitted.

Title: Improvements in or relating to the production of colloidal silver
IPC: G03C1/825
Filed: 1946-11-29
Abstract: Colloidal silver is produced by a process comprising reacting in an aqueous colloidal medium a soluble silver salt and a reducing agent therefor in the presence of colloidal silver sulphide or silver selenide.  In an example thiourea and silver nitrate are added to a solution of gelatine, digested at 125 DEG  F., and then cooled to 90 DEG  F.  Silver nitrate solution is then added followed by excess p-hydroxy phenylamine acetic acid dissolved in caustic soda.  Ethyl alcohol is added to precipitate the gelatin which is soaked in water then redispersed in water.  In a further example, selenourea is used in place of thiourea.  An alternative water permeable colloidal medium is an aqueous dispersion of polyvinyl alcohol; any silver salt soluble in water may be used, and whilst any reducing agent may be utilized the photographic developer type, e.g. hydroquinone, p-methylamino phenol sulphate, 1-phenyl-pyrazolidone-3, p-phenylene diamine and substitution derivatives are preferred.  The product is used in the production of filter and anti-halation layers in photographic materials.

Abstract: 356,862. Seating accommodation combined with safety harness. LARRARD, J. H., Royal Aircraft Establishment, South Farnborough, Hampshire. July 11, 1930, No. 21000. [Class 141.] An airman, driver, or the like of a mechanicallypropelled vehicle, particularly an aeroplane, is maintained in position on his seat notwithstanding sudden deceleration, and is allowed freedom of body movement by means of seating accommodation involving safety harness capable of ready release. Parachute harness or existing types of safety belts or the like may be used in connection with the apparatus. As shown, particularly for an aeroplane; a part 2 of the back of the seat is hinged so as to be capable of being tilted forward or locked in position under control of the pilot, independently of the means for securing the pilot, which latter means involve the use of converging guide tubes 8, 9, 10 carrying cables 12, 13, 14. A locking-pin 15 is controlled by a bell-crank lever 16. The hinged part 2 of the back of the seat is held in position by a spring catch 5 controlled by a Bowden wire or like remote control 7. Snap hooks 20, 21 attached to the cables are connected to rings 22, 23 on the parachute harness. The quick-release lever 16 for the cables is held in the down position by a spring-loaded pawl 24 engaging a notched quadrant and allowing an upward movement of the lever but preventing a return of same until the pawl is hand-released. Means, such as the well-known break-link device, which slip apart when freed from the anchoring tube, may be employed to release one or each of the cables as it is withdrawn from the tube. Different arrangements for connecting the snap hooks to the harness are described.

Abstract: 1517914 Reinforcing cords; non-woven fabric DUNLOP Ltd 14 Aug 1975 [22 Aug 1974] 36889/74 Headings D1R and D1T [Also in Division B7]  A reinforcement for a flexible article comprises at least one layer of parallel cord fabric of cords comprising at least two strands of wires, the direction of lay of the wires in each strand of a cord being the same as the direction of lay of each strand in the cord, and the cords having an elongation at break of not more than 5%. Preferably the cord strands are arranged such that the elongation of the cords at break is less than 4% and more preferably in the range 1 to 3%. The strands may each extend helically such that the cord is coreless or there may be one strand acting as a central core. If a core strand is present it should be surrounded by at least two outer strands wound such that each outer strand is adjacent both the core strand and at least one other outer strand. Adjacent strands may be either in direct contact with each other or separated by a film of rubber or other material. The strands may be twisted around each other or laid around each other with zero twist. Similarly the wires of each strand may be laid with or without twist. The wires forming each strand may be either cored or coreless but where one strand is to be used as a core strand it is preferable that said strand is coreless so as not to inhibit unduly the extensibility of the cord. The cords in the reinforcement layer may all have the same direction of lay. Where cords of opposite lay are present in a layer, successive adjacent cords may be of opposite lay to give a balanced construction. The cords may be provided with a helically extending wrapping wire to assist in improving handling. The use of Lang's lay cords for forming reinforcement has been found to reduce the energy consumption by the reinforcement during flexing as compared with a similar reinforcement comprising regular lay cords. When the fabric is embedded in a sheet of rubber and subject to flexing, the resulting hysterisis loop that is used to measure the energy loss set up during cyclical bending is less than that for corresponding test samples using similar reinforcement comprising regular lay cords. The cords may each be formed from three strands, each of ten brass-coated carbon steel wires of 0.18 mm diameter.
