Title: Improvements in or relating to television and like systems and circuits therefor
IPC: H04N5/08
Filed: 1935-06-06
Abstract: 457,812. Television. McCONNELL, E. D., and BAIRD TELEVISION, Ltd., 58, Victoria Street, Westminster. June 6, 1935, No. 16515. [Class 40 (iii)] A circuit for separating television picture and synchronizing signals comprises a thermionic separating valve adapted to act as a rectifier and a substantially unilateral conductor, such as a metal rectifier, diode or crystal, in series with, in parallel with or in place of the grid resistance of the valve. According to a modification, two such conductors are employed, one connected in parallel with or in place of the grid resistance of the valve and the other in series with this resistance. Fig. 1 shows an arrangement in which synchronizing impulses mixed with picture signals are applied from a valve 3 through a condenser 4 and a rectifier 5, connected in series with the grid resistance 2, to the grid of the separating valve 1, the rectifier being connected in such a sense that it presents a high impedance to the positive picture impulses so that only a small potential variation occurs across the resistance 2 but a very low impedance to the synchronizing impulses so that practically the whole amplitude of these impulses is applied across the resistance 2. Fig. 2 shows a modification employing two rectifiers 5, 6 arranged as shown, the valve 1 being biassed to act as an anode bend separator. In this arrangement, the rectifier 5 is connected so that it presents a low impedance to the positive impulses and a high impedance to negative impulses whilst the rectifier 6 is connected so that it presents a high impedance to positive impulses and a low impedance to negative impulses. Specification 443,031 is referred to.

Abstract: 1,069,309. Sewing machines. L. & L. MANUFACTURING Inc. April 15, 1966 [April 20, 1965], No. 16725/66. Heading D1G. A sewing machine comprises means for receiving and yieldably pulling a thread chain in advance of a work piece, said means being arranged, after the insertion of a few stitches in the work piece, to move the thread chain across the line of stitching, whereby the thread chain is incorporated in the stitched seam, said means then returning to its initial position. As shown, a hollow horizontal arm 30 communicates at its inner end with a suction duct 35, and is movable counterclockwise about the axis of the latter, upon energisation of a rotary solenoid 32, against the bias of a spring 33, from an initial position A in advance of the stitching print of an overedge sewing machine to a final position B to the rear of the stitching point. The outer end of arm 30 extends downwards and has an opening adapted to seize the thread chain 25 extending rearwardly from a previously-sewn workpiece. When a fresh workpiece presented to the machine obscures a photocell PEI, the machine starts and continues to run until the workpiece obscures a photocell PE2, whereby the driving motor is de-energised and a brake coil is energised to stop the machine. The presser foot is raised, after a time delay, to actuate a lever 38 for actuating a limit switch L55. Solenoid 32 is thereby energised for moving arm 30 to position B, where arm 30 actuates a limit switch L54. The presser foot is thereby lowered and the machine is re-started, whereby the thread chain 25 is incorporated in the seam until the usual edge-trimming blades 22, 23 sever the thread chain, the free end of the latter then being conveyed to duct 35. Arm 30 which is retained in position B by time delay means, then returns to position A. When a sewn workpiece obscures a photocell PE3 the machine will stop, unless a fresh workpiece has subsequently obscured photocell PE1.

IPC: G01N33/20
Filed: 1975-04-24
Abstract: 1501708 Solid electrolyte oxygen probe MECI MATERIAL ELECTRIQUE DE CONTROL ET INDUSTRIEL 24 April 1975 [6 May 1974] 16947/75 Heading G1N The response time of a solid electrolyte probe with metal and/or metal oxide reference for measuring oxygen content of molten metal is reduced by an ecothermic reaction in the reference medium. The reaction is preferably a redox  reaction which is initiated by the molten metal bath and the reaction products do not substantially modify the reference pressure. The reaction is caused by the presence of a different metal and/or a different metal oxide in the reference medium, the added material being determined from the following conditions:- (a) The reference is a metal and/or its lowest oxide and a metal having a greater affinity for oxygen is added. When the metals are from the list Ni, Co, Mo, Cr, Mn, Ta, V, "Si", Ti, Mg, Al and Zr, the reference may be any of the first four and the added metal any one following the reference. (b) The reference is a metal and optionally its lowest oxide and an oxide of a metal having a lower affinity for oxygen is added. When the metals are from the list Fe, Cu, Ni, Co, Mo and Cr, the reference may be any of the last four and the added oxide that of any metal preceding the reference. (c) A combination of (a) and (b). When the metals are from the list Fe, Cu, Ni, Co, Mo, Cr, Mn, Ta, V, "Si", Ti, Mg, Al and Zr, the reference may be one of Ni, Co, Mo and Cr, the added metal one which follows the reference and the added oxide of a metal which precedes the reference. Calculations for the amounts of each material are quoted and details of unsuitable or unsafe combinations are given.

Title: Internal combustion engines
IPC: F02M61/16
Filed: 1971-05-25
Abstract: 1344523 IC engine fuel and anti-detonant injection G M LOBY 25 May 1971 [25 June 1970] 16949/71 Heading F1B In a method of feeding an IC engine a metered quantity of fuel is injected into a cylinder at the moment of maximum swept volume and a detonation inhibitor is injected by mechanical means into the combustion chamber substantially simultaneously with the injected fuel. A cam 3 operates the fuel injector needle 14, Fig. 2 through a rocker 5, slideway 6, link 9, lever 12 and link 13 to admit anti-detonant through passage 24 and fuel through passage 23 into the cylinder at 17 in opposition to the inflowing air charge. The valve needle is lubricated through orifices 21, 22 from the lubrication system. The fuel and anti-detonant, e.g. water, is fed to the injector by a dual pump driven by an electric motor 32, Fig.5 the outputs of which are connected to rails 43, 44, Fig. 1 feeding inlets 19, 20, Fig.2. The speed of the electric motor 32 is increased for engine starting. The connection of link 9 with slideway 6 is varied through a rack and pinion 11, lever 10 and link 8 to control the stroke of needle 14 and thereby the quantity of fuel injected. Rack 11 may be controlled manually or by a device responsive to inlet manifold pressure downstream of an air inlet butterfly valve. When the air inlet valve is closed and the engine is over-running a second inlet manifold pressure responsive device moves the connection of link 9 to the zero fuel delivery position. In modifications the slideway may be formed in an end of lever 12, the combined injector may be replaced by two separate injectors positioned in the cylinder head. Oxygen may be injected with water to form a hydrogen peroxide detonation inhibitor.

Abstract: 506,875. Refining cellulosic materials. EGGERT, J. W. June 8, 1938, No. 16978. Convention date, Sept. 11, 1937. [Class 2 (ii)] Straw, e.g..grain straw, and other plant materials containing silica are first subjected to treatment with an aqueous solution of a salt having a reducing action, e.g. sodium or potassium sulphite, at a temperature of 120- 130‹ C. so. as to remove all water-soluble constituents. The extraction liquid may also contain a phosphorous salt. The materials are then subjected to treatment with a solution of caustic soda containing a reducing salt at a temperature of 140-160‹ C. The lye is subsequently removed from the treated cellulose rapidly and completely whilst in a hot state. The cellulose material may then be subjected to the action of chlorine in a concentration of 0À43-1 per cent in aqueous solution at a temperature not exceeding 17‹ C. Buffer substances are present during the chlorination treatment so as to prevent acid formation. The material may then be subjected to a further treatment with alkalies, alkaline earths; or alkaline salts. The final alkaline treatment may be effected with concentrated alkalies or alkaline-earth hydroxides at low temperature. An anti-chlor, e.g. sodium sulphite may be added to the solution, and the alkali may then be washed out by means of low-pressure wet steam. The cellulose pulp may be acidified before the last washing process. The cellulose pulp may be used for making cellulosic solutions.

Title: Improvements relating to transaction counters for cash registers and like machines
IPC: G06C7/10
Filed: 1920-07-22
Abstract: 170,808. Haddan, A. J. H., (National Cash Register Co.). July 22, 1920. Cash registers; item and operation counters; counting-apparatus actuated by reciprocating mechanism.-In machines of the type described in Specifications 127,228 and 127,237 the special transaction counters are operated by toggle mechanism through a common actuator, the selection of the particular counter to be operated being effected by a sector positioned differentially under the control of the transaction bank. The four counters 75 are actuated by pawls 80 on arms 82 connected to one member of a pair of toggle arms 92, 87. A pin 88 on the arm 87 can slide freely in a slot 89 unless obstructed by the positioning of a projection 96 - - 99 formed on a plate 95 differentially positioned according to the transaction. When the machine is operated, a sector 106 carried by a bell-crank lever 101, 102 is oscillated and by slotted connection with the central pins 86 on the toggles causes the latter to straighten. The pin 88 appertaining to the counter concerned in the transaction cannot slide owing to the obstruction by the plate 95, and consequently its toggle is straightened in the outward direction and operates the counter.
