Title: Improvements in or relating to moulds for centrifugal casting machines
IPC: B22D13/00
Filed: 1919-11-18
Abstract: 154,062. Hurst, J. E., and Stokes, F. W. Nov. 18, 1919. Drawings to Specification. Casting-machines; moulds.-The inner surface of the mould of a centrifugal casting-machine is maintained at 600 to 700‹ C. The mould may be originally heated by electricity or gas or by making a number of castings which are scrapped; by adjusting the thickness of the mould and rate of casting, this temperature may be maintained. For an iron casting 5 to 10 millimeters thick and weighing about 15 lb., a cast iron mould should be 2¢ to 3 inches thick and the castings produced at 40 to 60 per hour. If a liner is used, it should be in intimate contact with the body of the mould.

Abstract: 772,677. Jigging conveyers. PACKAGE MACHINERY CO. Oct. 6, 1954 [Nov. 20, 1953], No. 28794/54. Class 78 (1). [Also in Group XVIII] Jigging conveyers feeding the hopper of an automaticfeed weigher (see Group XVIII) operate as follows: Powdered material flows from a container 11 having an adjustable door 16 to a trough conveyer 12 jigged by a vibrator 19, and thence to a shoot 23 hinged at 15. Excess material on the shoot causes it to drop, thereby actuating a switch 28, through counterbalance arm 26 and springs 27, to stop vibrator 19.

Title: Improvements in carburettors for internal combustion engines
IPC: B43K21/06
Filed: 1945-10-30
Abstract: 615,436. Spray carburetters. ROUQUETTE, G. F. Oct. 30, 1945, Nos. 28796, 28797 and 28798. Convention dates, Dec. 22, 1943, Oct. 20, 1944, and Oct. 26, 1944. [Class 7 (iii)] The end of a fuel nozzle 17, disposed in the throttle valve 10, is notched at 20, Fig. 5, on the substantially plane upstream side to reduce the suction on the fuel jets 36 at slow-running, leaving the slow-running jet 51 alone in action. A hollow portion 16 of the throttle shaft 15 is formed with slits 32 which on rotation of the throttle bring the jets 36 into action in succession, emulsifying air being supplied through a chamber 49 and tubes 44, Fig. 3. The shaft 15 is separate from the throttle valve and is clamped thereto by a nut 24 acting through the control lever 21 and a sleeve 25 to force the shaft against a shoulder 22. Slots 30 may be provided to make the part 16 of the shaft resilient, a seal being maintained by a sleeve 31 of synthetic rubber. A plug 54, controlled through a lever 55 by hand or by a barometric capsule, forms an altitude control, and the slow-running jet 51 opening into the intake pipe near the throat 9 of a detachable venturi member 8 is controlled by a lever 52. In a carburetter, Fig. 6, in which the nozzle 75 is supplied with fuel under pressure through a valve 78 and orifices 69, 70 controlled by a valve box 65 rotating with the throttle shaft 63, the fuel supply is arranged to be completely cut off when the engine is stopped. The valve 78 is urged to closing, by a weak spring 79 and is opened during running by engine suction transmitted to the space above a piston 81. When the engine is stopped, a strong spring 91, normally held clear of the stem of valve 78 by a pin 92 co-operating with a cam 94 on the box 65, assists the spring 79 in keeping the valve 78 closed. The Specification as open to inspection under Sect. 91 comprises also a needle controlled either manually or by a barometric device regulating the size of the slow-running orifice 97, and the cam 94 is formed separately and operated by a lever connected to the ignition contact control. Adjustable stops regulate the maximum opening and closing positions of the throttle valve. In Fig. 15 (Cancelled), the cam 94, which comprises a sleeve controlling an air inlet 135, raises the spring 91 gradually, thereby controlling the fuel flow through the nozzle 80 in accordance with the throttle opening. In a further modification, applicable to a downdraught carburetter, the spring 91 is actuated by a link connected to the throttle control lever and actuating a push-rod. This subject-matter does not appear in the Specification as accepted.

Abstract: 346,013. Annealing. VEREINIGTE STAHLWERKE AKT.-GES., 67, Breitestrasse, Dusseldorf, Germany. Sept. 23, 1929, No. 28854. Convention date, Oct. 24, 1928. [Class 72.] Ferromagnetic alloys of suitable composition are quenched from such temperatures, depending on the alloy treated, that a supersaturated solution of the alloying component in alpha-iron is obtained. The supersaturated solution is destroyed by reheating and enhanced magnetic properties are thereby obtained. The ferromagnetic alloys treated are those in which the solubility of the phase existing at room temperature increases with temperature, i.e. those having a solubility curve such as XY, Fig. 1 or Fig. 2, which show temperature-concentration diagrams for iron-tungsten and iron-carbon alloys, which are typical of alloys having closed and open gamma-fields respectively. The alloy is quenched from a temperature above that at which the solubility of the alloying component commences to increase, i.e. above the point S, but below the line PYQ, Fig. 1, or GYK, Fig. 2, and reheated to a lower temperature, preferably below the point S. In the case of binary open gamma-field alloys, examples of quenching temperatures are iron-carbon 500- 720‹ C., iron-nitrogen 300-600‹ C., iron-copper 500-800‹ C., iron-zirconium 600-900‹ C. In the case of binary closed y.field alloys, examples of quenching temperatures are iron-tungsten 900-1500‹ C., iron-molybdenum 900-1500‹ C., iron phosphorus 900-1100‹ C., iron-silicon 700-1200‹ C., iron-aluminium 700-1200‹ C., iron-titanium 800-1300‹ C., iron-beryllium 700-1200‹ C. The proportions of constituents in the alloy treated are defined by the corresponding temperature-concentration diagram. According to the Specification as open to inspection under Sect. 91 (3) (a) reheating may be replaced by ageing alone. This subject-matter does not appear in the Specification as accepted. Reference has been directed by the Comptroller to Specifications 2273/04, 22130/05, 26664/06, 210,388, 248,996, 260,835, 274,016, 288,579, and 300,553, [all in Class 72, Iron &c.].
