Patent GB-928455-A (GB)
Title: Improvements in or relating to flameproof equipment
IPC: H01H9/04
Filed: 1959-10-14
Abstract: 928,455. Photo-electric control of heating apparatus. R. W. OSWALD. Jan. 16, 1961 [Oct. 14, 1959], No. 34892/59. Class 40 (3). [Also in Group XXI] Flame proof equipment, e.g. electrical or electronic equipment has its interior connected to the atmosphere through a drying agent which is heated to drive off absorbed moisture when air is passing out of the equipment through the drying agent but not heated when air is passing into the equipment. The drying agent e.g. silica gel is adapted to have a greater water absorption capacity the lower the temperature. In the case of equipment in which the functional parts generate heat when they are operating, for example a filament lamp, it is generally unnecessary to provide auxiliary heating means for the drying agent. The drying agent may however be heated by an auxiliary heating means which is actuated by a device which is sensitive to the flow of air from the enclosure of the equipment, for example by means of a vane, Venturi, or Pitot, or by a device sensitive to a difference in pressure between the enclosure and the atmosphere, for example by means of a manometer or bellows. In the case of equipment in which air passes outwardly due to a rise in temperature or when the outward passage of air is associated with the emission of light, the heating element can be actuated respectively by means of a thermometric device or a photocell. When periods of time during which outward passage of air takes place are previously known, the heating element can be controlled by a time clock. According to the Provisional Specification when the outward passage of air is due to heating associated with light, e.g. the sun the heating element may be actuated by a photo or selenium cell.

Abstract: 777,111. Metal wire feeds. JOHN BULL RUBBER CO., Ltd. Dec. 17, 1954 [Dec. 18, 1953], No. 35239/53. Class 83 (4). Apparatus for cutting wire into lengths consists of a device for pulling wire through the shearing machine, a wire tensioning arrangement and a gripper which allows the wire to move freely in the feeding direction but prevents reverse movement of the wire. The gripper consists of a block 12 and a bar 15 connected by parallel links 16 to the block 12. The wire 1 passes through guide and feed pulleys from a bulk supply to a reciprocating gripper 8 and is tensioned by a pulley 5 carrying a weight 10. The end 9 of the wire is fed through the guillotine by one stroke of the gripper 8 which is driven by a pneumatic motor 27, and is then attached to a winding drum. The gripper 8 is retracted and the winding drum pulls the required length of wire through the guillotine, the wire sliding freely through the gripper 8. The wire is cut and the cycle of operations restarted. Cams on the shaft of the winding drum operate the guillotine which actuates a rocker arm controlling by a valve the supply of air to the cylinder of the motor 27.

IPC: C22B26/22
Filed: 1935-12-23
Abstract: In the production of magnesium from magnesium compounds such as the oxide, the compound is first treated to produce magnesium nitride, the nitride is heated with sulphuretted hydrogen at about 900 DEG  C. to obtain magnesium sulphide, and the sulphide reduced by heating with calcium carbide in an atmosphere of a reducing gas such as hydrogen or gaseous hydrocarbons or of an inert gas such as argon, and in the substantial absence of moisture, nitrogen or oxygen.  The nitride may be formed by passing nitrogen through a powdered mixture of magnesium oxide and a carbonaceous reducing agent at say 1500 DEG C. in the absence of moisture.  The magnesium may be distilled off in a current of gas inert towards magnesium and be collected in vacuo or in an atmosphere of hydrogen, argon, or other gas having no action on liquid or vaporized magnesium. The magnesium vapours may be directly combined with other metals such as aluminium or beryllium to form alloys therewith.
