Title: Improvements relating to electric arc welding devices
IPC: B23K9/133
Filed: 1934-08-01
Abstract: 437,470. Uniting by fusion. CARNAC, A. J. RIVETT-, Brandeston, Fort Brown, Grahamstown, South Africa, and ASSOCIATED ELECTRICAL INDUSTRIES, Ltd., Crown House, Aldwych, London. Aug. 1, 1934, No. 22494. [Class 83 (iv)] In an arc-welding machine of the kind in which bare or flux coated electrodes are fed to the work by and current at the same time supplied thereto by sharp projections or spurs successively engaging the electrode, the current to a spur is interrupted prior to disengagement of the spur from the electrode so as to avoid arcing in the feed gear. The electrode 29 may be fed by a series of pairs of sharp spurs 9 mounted radially on a toothed wheel 1, which is carried by a shaft 2 rotating in bearings 3 in a pair of sleeves 4 secured to a rigid frame 5. The fixed spurs are secured on the wheel by insulated studs 10 and the movable spurs are secured by insulated studs 11 to levers 12 pivoted at 13 in insulated blocks 14 on the wheel. The levers have rollers 15 held by springs 28 in contact with a cam 16 secured to the sleeve 4. The levers also carry spring- pressed contacts 18 which are electrically connected by flexible conductors 24 to the studs 11. The studs 10 and 11 are also electrically connected to each other by flexible conductors. The arrangement may be such that four pairs of grippers engage the electrode contemporaneously. The contacts 18 during rotation of the wheel successively engage fixed contacts 32, 33, 34, the contacts 32, 33 being connected to each other through a switch A and the contacts 33, 34 through a switch B, and the contact 33 being connected to one terminal of the current supply, the other terminal of which is connected to the work. These switches are connected to a lever operated by a sprocket secured to the wheel. When the rear pair of spurs of a set is operated by the cam so as to grip the electrode the switch A is open and the switch B closed, so that current is supplied only to the two intermediate pairs, the forward pair being released from the electrode. On further rotation of the wheel the switch A is closed to apply current to the rear pair and the switch B at the same time is opened to break the current to the second pair prior to releasing thereof from the electrode at a subsequent stage. In the form shown in Figs. 6 and 7, the grippers 44 consist of pairs of spurs 45 connected by toggles to levers 50, which are pivoted at 47 on brackets 48 secured to an endless chain 40 or belt mounted on driven sprockets. The levers carry rollers 51 held by a spring 52 in contact with cam surfaces 57 when in feeding position. The levers also carry contacts 53, which are electrically connected to the spurs and engage a pair of fixed elongated contact bars 58 connected to the supply. The length of the cam surfaces 57 and bars 58 is such that the cams close the spurs before the contacts are engaged and permit disengagement of the spurs after the contacts are opened.

Patent GB-819368-A (GB)
Title: Improvements in or relating to electric pulse circuits
IPC: G06F5/01
Filed: 1956-07-24
Abstract: 819,368. Electric digital-data-storage apparatus. WESTERN ELECTRIC CO. Inc. July 24, 1956 [July 25, 1955], No. 22859/56. Class 106 (1). [Also in Group XXXIX] A pulse circuit comprises a plurality of magnetic cores connected alternately in two groups with separate shift pulse means connected to each of the two groups, gating means connected to each core adapted to be actuated by the output signal from the immediately prior core, and a third pulse source connected to all the gating means whereby the transfer of a pulse between adjacent cores renders the associated gating means conductive, thereby permitting the application of a pulse from the third pulse source via the conductive gating means to the output means. The arrangement described comprises gating means enabling information in the form of pulses from a source 12 to be entered sequentially into the column electrodes of a ferro-electric storage matrix 10. A single pulse is stored in the register and opens in turn each of the transistor gates such as 14 as it is shifted from one core to the next. Each core such as 26 has three windings such as 27, 28, 29, shift pulses being applied from a source 24 to the windings 27 &c. of the first group of cores, and from the source 25 to the windings 31 &c. of the second group of cores. If a binary one is stored, for example in the core 26, it will be transferred to the core 32 in the other group by the current induced in the output winding 28 on reversal of the magnetization of the core 26 by the shift pulse from source 24, which current causes a flux change through the core 32 via an input winding 30. A transistor 15, associated with this input winding is normally biased by a battery 20 to cut-off and is rendered conducting by the passage of the transfer pulse thereby enabling a pulse from the source 12 to pass to the associated column electrode 13 of a ferroelectric storage matrix 10. Similarly, the next shift pulse, from the source 25, transfers the binary one stored in the core 32 to the core 34 of the first group, thereby enabling an associated transistor 16 to pass a pulse from the source 12 to the next column electrode 13. In this way, shift pulses applied alternately from the sources 24, 25 step the binary one digit registered from one core group to the other group, thereby sequentially opening the transistor gates 14 ... 17 &c. associated with those cores to which the binary one is transferred. The output coil of the last core of each group may be connected to the input core of the first core of the other group to provide a circulatory system. A transfer pulse is prevented from actuating a prior core by providing more turns to the output winding than the input winding of each core and suitably biasing the transistors. An alternative arrangement in which information is transferred in parallel from the cores to the output under the control of a single pulse from the source 12 is mentioned. U.S.A. Specification 2,695,397 is referred to.

Abstract: 1,013,671. Gas turbine plant. ZAVODY V. I. LENINA PLZEN, NARODNI PODNIK. June 18, 1962 [June 16, 1961], No. 23380/62. Heading F1G. A gas turbine plant comprises a high pressure turbine 18 driving a compressor 15 and a low pressure turbine 17 driving an alternator 16. The plant fuel supply is normally controlled by a governor 11 responsive to an input signal +X 1 , proportional to the speed of the first turbine 18 in combination with a governor 10 responsive to an input signal +X 5  proportional to the alternator output. The outputs -X 2 , +X 5  from the governors 10, 11 respectively are fed to a mixer node 21 and the combined output -X 6  regulates the fuel supply to the combustion chamber 19 through a control member 12. An overrriding control is actuated when there is a sudden rapid change in alternator output; which change operates a two-position shunt member 13 and cuts out the normal control. The member 13 regulates the fuel flow, through the control member 12, to the minimum required for maintenance of combustion and simultaneously opens a valve 14 in the compressor pressure line thereby preventing the alternator exceeding its trip speed. As the alternator approaches steady running conditions, the override control cuts out and the normal control is restored.

Title: Improvements in the manufacture of soaps
IPC: C11D17/00
Filed: 1947-08-27
Abstract: A cake of soap is formed of at least two separate juxtaposed pieces of soap in each of which is incorporated a chemical reagent, the two chemical reagents being of a different nature and such that when they are contacted by means of washing water, they react exothermically one on the other.  Cold water is thus rendered more pleasant in use with soap, particularly in shaving. The pairs of reagents may comprise a base with an acid, such as soda or potash and sulphuric acid, bromine with iodine and a bromide or an iodide with chlorine. The soap cake may comprise several alternate layers of the two treated soaps, or the two soaps may be cut into small pieces, re-combined and moulded into heterogeneous cakes, the surface of which is a mosaic.  In another form, the two soaps may be separated by a piece of neutral soap, i.e. containing none of the reaction constituents of the two soaps, to prevent the two soaps from reacting one on the other before use in water.  The two soaps may be combined cylindrically, with or without a neutral layer therebetween, particularly for making shaving sticks.  More than two pieces of soap, each containing a different reagent, may be used, the resultant effect of the reagents merely producing an exothermic reaction.  The soaps are the usual soda, potash and ammonia soaps.
