Abstract: A device 1 for filtering liquids comprises a pipe with a wall section 5 designed as filter, a liquid inlet 3 to the pipe, a material discharge outlet 29 for evacuation of the material filtered out and a collecting element 9 for the filtered liquid.  The device has a cleaning element in the form of a piston 13 with a piston face 14 facing towards the material discharge outlet.  At suitable intervals a drive element 11 moves the piston into the filter, so that this is scraped clean of the material filtered out.  A valve 13 situated between the filter and the material discharge outlet 29 is normally closed, so that the piston 13 can compress the material filtered out. When a sufficient quantity of material has been collected the valve 15 opens and the piston 13 pushes the filtered material out of the device. <IMAGE>

Abstract: 419,634. Electromagnetic switches. COMPAGNIE POUR LA FABRICATION DES COMPTEURS ET MATERIEL D'USINES A GAZ, 12, Place des Etats-Unis, Montrouge, Seine, France. Jan. 2,1934, No. 159. Convention date, Jan. 13, 1933. [Class 38 (v).] In tuned relay arrangements responsive to exciting currents of particular frequencies, in order to prevent inadvertent operation of the tuned relay apparatus by likely disturbing frequencies such as harmonics of the line frequency on which the operating frequency or frequencies are superimposed, supplementary vibrating members tuned to such likely disturbing frequencies are provided, the free vibration of such supplementary vibrating members being effective in preventing operation of any of the members tuned to predetermined operating frequencies. The tuned operating systems may be electrically and/or mechanically tuned to the operating frequencies. On occurrence of a disturbing frequency the free vibration of the supplementary vibrating member tuned to that frequency is arranged to produce a counter electromotive force in the electromagnet or electromagnets controlling the operating tuned members so that the latter are not vibrated sufficiently to produce operation of the relay apparatus while such disturbing frequency is present. The above arrangements may be combined with filter circuits for eliminating the effects of certain other disturbing frequencies.

Title: Improvements in or relating to electrical inverter arrangements
Inventor: KING KENNETH GORDON
IPC: H02M7/5383
Filed: 1960-01-05
Abstract: 950,186. Inverting. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. Jan. 5, 1961 [Jan. 5, 1960], No. 306/60. Heading H2F. [Also in Division H3] An inverter comprises two switching devices for connecting a transformer in alternating polarity to a D.C. supply, and a capacitor connected to the control terminals of the switching devices via a breakdown device and arranged to be charged from a secondary winding of the transformer, whereby when the device breaks down the polarity of the said connection to the supply is reversed. The Figure shows a transistor push-pull inverter of the type having regenerative feedback from collector windings 2, 3 to base windings 4 and 5 and feeding a load 8. A further winding 6 charges a condenser 20 through a resistor 19 until the voltage across the condenser is sufficient to cause a breakdown device 26 to change from its high conducting condition to a low conducting condition. This causes the condenser to apply to the bases a voltage such that the conductivity conditions of the two transistors reverses. The condenser discharges causing the device 26 to become highly non-conductive again and the condenser then charges in the opposite direction until break down again occurs and causes a further reversal of the conducting condition. The diode bridge 22, 23, 24, 25 permits the device 26 to be operative in one direction only but may be omitted, in which case, if device 26 is asymmetrical, the output waveform will be asymmetrical. Two devices connected back-to-back may also be used. As a further alternative, a three electrode breakdown device may be used, control of the frequency of operation being effected by a current supplied to the third electrode or by synchronizing pulses applied to the electrode. To minimize variation of frequency with supply voltage changes the voltage output of the winding 6 may be stabilized by a Zener diode circuit. Initiation of oscillation on switching on may be ensured by connecting a resistance between a negative supply terminal and the base of one transistor.

Title: A method of testing composite metallic material

IPC: G01N33/20
Filed: 1952-01-04
Abstract: 715,777. Testing physical qualities of materials. GLACIER METAL CO., Ltd. Dec. 15, 1952 [Jan. 4, 1952], No. 334/53. Class 106 (2) A method of testing the continuity of the matrix phase in a composite metallic material comprising two or more constituents, the melting points of which differ from one another, and in which a lower melting point constituent is embodied in a matrix of a higher melting point constituent, comprises subjecting a test piece of the composite metallic material to mechanical stress at a temperature above the melting point of the lower melting point constituent and below the melting point of the higher melting constituent, and using the results of the test to assess the continuity and characteristics of the matrix material. The mechanical stress may be compression, shearing, bending, elasticity or any combination thereof, for example, both tensile and fatigue tests may be employed together. The data derived from the tests may be analysed statistically in order to correlate the desired results with the conditions required to produce these results such as that described in " Industrial Experimentation " by Brownlee, published by H.M.S.O., 1949. The method of testing may be applied to any composite material of two or more phases whose melting points differ from one another, such as, for example, aluminium-tin alloys or copper-lead alloys. The method of testing is described with particular reference to copper-lead alloys, and is designed to provide data on the continuity of the copper matrix, or sponge, in metal employed for bearings, upon which factor both the heat conductivity and strength depend.

Title: Improvements in speed limit signal or indicating devices for speedometers
IPC: G01P1/10
Filed: 1929-01-28
Abstract: 328,581. Kourtzman, P. A. Jan. 28, 1929. Divided on 328,565. Indicators, speed.-Relates to apparatus in which an indicating member on one end of a double-armed lever is moved to an indicating position on the speed limit being reached by operation of the arm by means of a centrifugal device, and consists in means for temporarily maintaining this indication. The device is shown applied to a speedometer which has a diagram cylinder with an adjustable cord, a counting mechanism and a speed limit indicator or signal. A diagram cord 12 is located between a cylinder rotated according to distance traversed and a fixed transparent wall 13 and rotates with the cylinder. A band 15 movable vertically by a centrifugal device (not shown) according to speed carries a short tube 16 through which the cord 12 passes freely. The band 15 overlies and is attached at one end to a pulley 17 which is attached to a couple of sprockets which are operated by the centrifugal device to move the band 15 against the influence of a spring exerting a pull on the band in the opposite direction. When the speed limit is exceeded, a projection on the wheel 17 engages one arm 39 of a doublearmed lever 39, 37 raising the arm 37 to expose a signal 40 at a hole in the casing. The doublearmed lever is slidable on its pivot pin against the influence of a spring. A tooth 42 on the signal arm, on the speed limit being exceeded, engages a thick screw 43 rotated from a counter wheel so that the lever slides on the pivot pin. The signal arm is free to return as long as the tooth 42 engages the screw 43. When the excess speed lasts beyond a certain distance, the tooth engages a smaller screw 48 driven from another counter wheel whereupon the tooth 42 passes behind a friction surface (not shown) and the signal is retained until the tooth traverses the length of the screw 48.
