Title: Improvements in and relating to resistance welding apparatus
IPC: B23K11/11
Filed: 1945-08-27
Abstract: 634,636. Electric welding. BRITISH THOMSON-HOUSTON CO., Ltd. Aug. 27, 1945, No. 21973. Convention date, Aug. 31, 1944. [Class 83 (iv)] In a resistance welding apparatus having work-engaging electrodes operated by mechanical pressure, additional pressure is supplied to the electrodes during welding by a lever mechanism which is operated by magnetic repulsion set up by the flow of welding current. The electrodes 5, 6, Fig. 1, are supported in arms 3, 4 of a frame 1 and normal welding pressure is supplied by a cylinder 10, integral with the upper arm, and connected to a pipe 14 for fluid inlet and exhaust. The pressure is imparted to electrode 5 by a piston 11 bolted to it by means of flanges 16, said piston being biassed upon a spring 15 to hold the electrode 5 off its counterpart 6. A transformer in the frame supplies welding current to the lower electrode 6 through arm 4 and to the upper electrode through flexible conductors 17, lever 18 and links 19. The lever is supported by a strap 22 which may be constructed of an insulating medium or a part 23 of the arm 3 may be insulated so that whatever position of three the strap occupies it will not make electrical connection with the arm. The lever is pivoted at 21 on the strap and has three fixing positions so that the magnitude of the additional force on electrode 5 may be varied. This force is produced by the reaction of the magnetic field set up by the flow of welding current in arm 4 and operates to turn the lever anti-clockwise whether it be A.C. or D.C. source or derived from a condenser discharge. The lever connection to the frame may be through a sliding contact such as a ball and arcuate strip and cooling tubes 24 for coolant flow to the bottom electrode may similarly be applied to the upper electrode. A compound. lever system may also be used.

Title: Improved method for the manufacture of yarn from artificial fibres and in particularfrom glass fibres
IPC: D01H4/02
Filed: 1948-08-20
Abstract: 694,561. Spinning yarns. SKLARNY A. RAFINERIE, DR. J. RIEDEL, NARODNI PODNIK. Aug. 20, 1948 [Aug. 20, 1947], No. 22040/48. Class 120(iii) Yarn is manufactured from artificial fibres, e.g. glass fibres, by suspending them in a fluid medium which is caused to rotate about an axis within a chamber and to move bodily parallel to the axis, collecting the yarn fibres on an element, e,g. a rod, within the chamber and withdrawing the element from the chamber in a direction opposite to that of bodily movement of the fluid medium, whereafter fibres continue to collect on the yarn itself. The fibres may be suspended in a gaseous medium which is fed tangentially at 1, Fig. 1, into a horizontal cylindrical chamber 2 the right hand end of which is open; to start the yarn, fibres are allowed to collect on a thin rod R which is then withdrawn from chamber 2 in the direction shown, fibres thereafter being, collected on the yarn itself. Alternatively. the fibres may be suspended in a liquid medium which is fed through a tube 5, Fig. 2, into a vertical funnel-shaped chamber 4 in a direction at an angle to the vertical axis thereof; a rod R is again used to start the yarn which is withdrawn vertically. The thickness and degree of twist of the yarn is varied by varying the rate of withdrawal of the rod.

Patent GB-1043447-A (GB)
Title: Pulse code signalling system
IPC: H04J3/17
Filed: 1964-05-29
Abstract: 1,043,447. Pulse code signalling systems. STANDARD TELEPHONES & CABLES Ltd. May 29, 1964 [June 3, 1963], No. 22301/64. Heading H4L. In a pulse communication system lulls in a first transmitted signal, e.g. a p.c.m. speech signal, are utilized for the transmission of a second signal, e.g. a data signal. In order to separate the two types of signal they are arranged to have a constant but different ratio of marks to spaces and tnis also serves to indicate the presence of errors. Transmitter.-P.c.m. speech signals are supplied from source 1 to a shift register 2 controlled by a clock 3. A matrix 4 is coupled to the shift register and arranged so that when it detects code groups representing zero amplitude of the speech signal an output is supplied on conductor 5. This inhibits gate 10 and set flip-flop 6 so that AND gate 7 is blocked and AND gate 11 is enabled and transfers a data character from store 13, via a matrix 14 which converts the data into code groups which do not occur in the coded speech, to a shift register 15. The shift register 15 under the control of AND gate 16, passes the data signals via AND gate 12 and OR gate 8 to the transmitter. If the code groups of source 1 are of the weighted binary type the matrix 4 may be arranged to translate the code groups into the constant ratio type code required, the pulse groups being supplied via a shift register 17 and gate 7. Receiver.-The incoming signals are supplied to a shift register 19 and to a circuit 20 for recovering timing information and providing pulses at bit rate on conductor 21 and code group rate on conductor 22. Matrix 23 checks each code group stored at 19 and provides an output on lead 25 when a p.c.m. speech signal is received, on lead 26 when a data code group is received, and an error signal on lead 24 when an incorrect signal is received. Shift register 27 is used if the shift register 17 is in use at the transmitter. An output on lead 25 causes the "0" output of flip-flop 29 to enable gate 30 and via OR gate 32 the " 1 " output of flip-flop 31 supplies the second enabling pulse to AND gate 30, permitting the p.c.m. signal to pass via OR gate 33 to the output circuit. With an output on lead 26 the " 1 " output of flip-flop 29 enables AND gates 34, 35, and via OR gate 32 the " 1 " output of flip-flop 31 provides the second enabling pulses for gates 34, 35, thus supplying data signals and data bit timing pulses to the appropriate circuits. The " 1 " output of flip-flop 29 is also supplied via OR gate 36 to pass a predetermined code group representing zero speech level from a coder 38 via gate 37 to the p.c.m. output. With an error signal on lead 24 the " 0 " output of flip-flop 31 is supplied via OR gate 36 to apply the zero code pattern to the p.c.m. output and the gates 30, 34 and 35 are disabled.

Title: Improvements in non-metallic electrical resistance bodies
IPC: H01C17/30
Filed: 1930-07-28
Abstract: 360,013. Resistance materials. BOSCH AKT.-GES., R., 4, Militõrstrasse, Stuttgart, Germany.-(Assignees of Biefeld, K. ; 17, Augsburgerstrasse, Munich, Germany.) July 28, 1930, No. 22638. Convention date, Aug. 3, 1929. [Class 37.] A resistance consists of a mixture of insoluble metal salts, the base of which is a metal forming compounds stable at high temperatures, while the acid radical is a heat-stable oxidation stage of a metal or metalloid. The acid radical of the salt may consist of an oxygen compound of iron, cobalt, nickel, manganese, tungsten, molybdenum, uranium, or chromium. The specific resistance may be regulated by the admixture of a nonconducting substance, for example oxides, silicates, borates, or other salts of light metals such as calcium, barium, strontium, magnesium, or aluminium. The conducting compound may be a heavy metal salt of light or heavy metals, for example copper chromate, iron tungstate, magnesium chromate, or aluminium ferrate, prepared by precipitation or fusion. Ferrosoferric oxide or ferrate of iron having the formula Fe(FeO2)2 may be employed and may be mixed with mangano-manganic oxide to obtain an increased negative temperature coefficient, or with chromic oxide to obtain a higher current-carrying capacity. The materials are finely ground and sieved, mixed in the desired ratio, and moulded under great pressure with or without binding agents such as waterglass, boric acid, &c. After drying, the resistance is annealed at about 1000‹ C., with or without sintering. The ends are metallized electrolytically or by spraying, for making connections thereto. Alternatively the pulverized resistance mass may be filled into an insulating container provided with current leads. Graphite or carbon powder may be added to prevent adherence of the particles. Instead of an insulating casing, a metal tube closed at the bottom and having a concentric rod or tube forming the other electrode may be employed, the current passing radially between the electrodes. The resistance unit may be insulated by a thin layer of enamel, giving a high efficiency for heating water or acid.
