IPC: H02J7/14
Filed: 1917-11-05
Abstract: 111,286. Akt.-Ges. Brown, Boveri, et Cie. Nov. 11, 1916, [Convention date]. Lighting systems; regulation, automatic systems and apparatus for; systems of charging galvanic batteries.-In lighting systems supplied by a generator and battery, the lighting voltage is maintained constant, when the generator h is supplying, by a variable lamp resistance adjusted by an electro-magnet having a coil f carrying the battery current and a coil e carrying the lighting current. The coils assist each other when the battery is discharging and oppose during charging. The resistance is made up of a fixed metal resistance b and an adjustable carbon pile a in parallel with the resistance b. The Specification as open to inspection under Sect. 91 (3) (a) also describes a switch having a coil i placed across the lamp resistance, the switch stopping the charging of the battery at a voltage below full charge when the generator is supplying the lamps. This subject-matter does not appear in the Specification as accepted.

Title: Method of extracting metals, more particularly lead, from drosses, slags or other metal-bearing materials
IPC: C22B13/02
Filed: 1947-06-19
Abstract: A method of recovering lead from leadbearing substances comprises heating 140 parts by weight of the substances with a molten mixture of 28 parts caustic alkali, 2 parts sodium cyanide, and 1 part vegetable black until a layer of liquid metal covered by a fluid flux is produced and subsequently separating the metal from the flux.  The lead-bearing substances may contain as impurities one or more other metals forming alkali-soluble oxycompounds, for example, antimony, tin or zinc, in which case the lead is recovered in combination with such other metal or metals.  The flux produced may be treated electrolytically (see Group XXXVI) for the production of further metal, which may have a spongy form and may be dried under pressure between absorbent material and then heated under a protective coating of caustic soda to form a layer of molten lead.  Specification 637,317 is referred to.

Abstract: 543,274. Electric motor control systems ; maintaining constant speed. IGRANIC ELECTRIC CO., Ltd. Nov. 8, 1940, No. 16251. Convention date, Nov. 8, 1939. [Class 38 (iv)] [Also in Group XXXVII]  In a speed control system for a slip-ring induction motor 1, speed regulation over a wide range is effected by manually-controlled movement of a short-circuiting brush 11 over the full extent of regulating resistances 3, 4, 5 in the rotor circuit, whilst automatic regulation to a constant slow speed is effected by speedresponsive means operating periodically to shortcircuit portions of the resistances 3, 4, 5 at contacts 10a, 10b, 10c until the brush 11 has been operated, also under the control of the speed responsive means to a position on the resistances which maintains speed at the desired low value regardless of the torque on the motor. The speed-responsive means comprises a relay 24 connected across the rotor circuit and adapted to respond only when the rotor voltage exceeds the value corresponding to the required slow speed. Its operation closes relay 10 and also energizes the " raise circuit of pilot motor 16 operating the cross-head carrying the brush 11. Both the " raise and " lower circuits of the pilot motor are subject to manual control by push-buttons 18, 19 for control of speed in the higher ranges.

Abstract: 752,024. Regulating. BROTHERSTON, A. C. and REBBE'CK, Sir F. E. June 3, 1954, No. 16466/54. Class 7(6) [Also in Group XXVIII] In a fuel injection pump in which the pump piston 1 is loaded by a spring 5 and actuated by a piston 2 subjected to the pressure in the engine cylinder, the delivery valve 10 is loaded by a pressure which corresponds to the maximum pressure occuring in the engine cylinder so that if this pressure increases, the time of injection is delayed. As shown in Fig. 1, the pump piston is rotatable and has an edge 20 which closes the outlet port 9 and the pump working chamber communicates through a non-return valve 18 with a chamber 14 having an accumulator piston 15 loaded by a spring 16 and a piston 13 which engages the valve 10; the piston 13 is additionally loaded by a spring 12 adjustable by varying the thickness of the washers 30. The chamber 14 is fitted with an adjustable leak-off 22. When the valve 10 is closed the delivery line 11 is relieved, to prevent drip, through the space 28 around the piston 13; this space is closed when the valve is lifted. In the construction shown in Fig. 2, the accumulator space 23 is connected through a non-return valve 29 with the engine cylinder and a piston 31 engages a spindle 13 to load the valve 10. Each time the valve 10 is raised, the piston 31 engages and opens the relief valve 32; the length of the stem of the valve 32 may be varied to adjust the leakoff.

Abstract: 631,013. Compound sheet materials. OPTREX, Ltd., GOODRICK, C. E. M., and THOMPSON, W. R. June 23, 1947, No. 16516. [Class 140] [Also in Group XVII] A container comprises plies of polymerized ethylene film shaped and adapted to form an inner container proper, and outer layers of a thermostable material disposed in juxtaposed relation to the outer surface of the plies of polymerized ethylene film, the latter plies being seam-welded together by application of heat and pressure, while the outer layers of thermostable material are caused to adhere to the inner plies. The thermostable material is one which is a good conductor of heat while retaining its solid form at moderately high temperatures below which would occur the softening or fusing point of the polymerized ethylene film. In the construction shown in Figs. 3, 4, a. sachet container for surgical dressings is formed from two superimposed blanks 2<SP>1</SP>, 41 of polymerized ethylene and regenerated cellulose film respectively, which are folded about a central axis at 9 and sealed together at 6<SP>1</SP> around the abutting free edges. The sealed area 61 may be crimped or embossed to increase the sealing action between the inner and outer materials. The embossing may be formed as a pattern or design or may constitute wording or identification inscriptions. In a modified construction (Figs. 1, 2, not shown), the container may be formed from two sets of superimposed blanks which are themselves superimposed and sealed all around the free marginal edges. This construction of container may be formed by bringing together webs of material fed from rolls and passing them between co-operating heating elements. The blanks may be of from 0.002 to 0.007 inches in thickness and may be of multi-ply formation. According to the Provisional Specification the edges of the outer blank may extend beyond the edges of the polymerized ethylene film and may thus be welded to each other during the sealing operation.
