Patent GB-1464538-A (GB)
IPC: F02D41/40
Filed: 1973-03-02
Abstract: 1464538 Automatic control of fuel supply in IC engines CAV Ltd 12 Feb 1974 [2 March 1973] 10343/73 Heading G3N A fuel control system for an engine has provision for modifying the output of the demand transducer in accordance with speed and is additionally provided with an idle governor which modifies the demand transducer output below a predetermined speed. The engine control system is basically similar to that described in Specification 1416862 with an idle governor circuit similar to that shown in Specification 1464378. In the present arrangement down transistors 54, 81 are provided in parallel with the demand transducer transistor 38 so that they all affect the current flowing in resistor 30 and thus the voltage applied to the control amplifier 17. The transistor 81 is arranged to conduct over the whole range of engine speed and so as the speed falls this transistor conducts more to increase the current flow in resistor 30. The transistor 54 conducts only below a predetermined speed and thus further increases the current in resistor 30 at low speeds. In a modification transistor 81 may be made non- conducting at higher speeds.

Title: Improvements in or relating to the manufacture of titanium pigments
IPC: C01G23/08
Filed: 1936-04-09
Abstract: White titanium pigments are prepared by the calcination of a mixture of precipitated and washed hydrated titanium oxide with an amount of an antimony compound corresponding to less than ,1 per cent of antimony, calculated on the titanium dioxide content. The antimony may be added as antimony trioxide or as tartar emetic, and at any time prior to the calcination, i.e. to the titanium hydrate pulp, to the titanium solution before precipitation of the titanium hydrate, or to the titanium ore before dissolving in acid.  Other "conditioning agents" such as phosphoric acid, phosphates, fluorine compounds, soluble alkali metal compounds, boric acid and borates, and also extenders such as barium or calcium sulphate, may be present.  White pigments are thus obtained which may have a pure neutral tone or a slightly bluish tone.

Title: Weighing and ticket-printing machines
IPC: G07F17/26
Filed: 1928-04-10
Abstract: 290,274. Rhodes-Hochriem Manufacturing Co., (Assignees of Hochriem, G. F.). May 13, 1927, [Convention date]. Weighing-apparatus. - A weighing and ticket-printing machine of the type wherein the printing of the weight of the person on the scale platform is effected through the medium of coin-controlled mechanism which brings into position a ticket to be printed and, upon the hand-operation of an actuating member, ejects the ticket from the machine, is provided with a simal device and means connected to the actuating member for operating the signal device to indicate to the attendant that the operation been completed and that the scale is in readiness for another operation. The invention is described in connection with a machine wherein the tickets are automatically cut from a continuous strip as described in Specification 277,600, but may be applied also to machines wherein the tickets are supplied from a magazine. As described in the abovte-meutioned Specification, after the insertion of a coin, an actuating member 153 pivoted on a pin 153<a> is pressed downward by the person on the scale platform and is then released, to return under spring action, thus effecting the ticket printing, cutting and delivering operations. During the downward movement of the actuating member 153 a pin 150 thereon, moves down an inclined face K in a lever G, C, and after rocking the lever to the right and reaching the limit of its downward movement, runs off the face thus allowing the lever G, C to return under spring action and cause a spring-mounted strike B upon the lever to sound a bell A. This signal informs the attendant in charge, that the machine is still in operation. As described in the abovementioned Specification mechanism is provided to prevent a reversal of the movement of the actuating member until a complete stroke has been made, and the coin slit is closed until the coin-actuated parts are re-set by the descent of the actuating member. Hence if the person on the platform fails to complete the downward stroke of the actuating member, no signal is given and the coin slot remains closed. When in this condition the machine might be regarded as out of operation by prospective patrons, and the absence of the customary signal warns the attendant.

A flat flexible electric cable comprises a plurality of parallel insulated conductors and a film of aromatic polyimide resin in contact with at least one surface of the conductors. The conductors may be embedded in the polyimide film or may be disposed between a pair of sheets of flexible insulating material of which one at least is the polyimide, and the other may be polyester, polycarbonate, polyvinylidene chloride, polyvinylidene fluoride, polyethylene, P.T.F.E., P.T.F.C.E. or a flexible fibrous material impregnated with flexible resinous material, particularly a polyimide resin. The polyimide resin is preferably a polyamideimide resin as described in Specifications 935,388 and 1,028,927. In a continuous process, copper foil 60 is slit by slitter 29 into a number of parallel conductors which are wetted by a solution of an aromatic polyamic acid 32 in tank 31. At the same time, a backing strip, e.g. of glass fibre is fed from reel 33 and impregnated with the resin solution and the conductors and backing are squeezed together by rollers 36, heated to remove solvent in tower 37 and to cure the resin in tower 38.
