Abstract: 1,174,243. Valves, fluid-pressure brakes. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. 6 Dec., 1966 [21 Dec., 1965; 29 April, 1966; 27 May, 1966; 8 July, 1966], Nos. 54066/65, 18817/66, 23776/66 and 30718/66. Headings F2F and F2V. A pressure control valve has an exhaust port 7 providing a seat for a throttling valve member 13 so as to set up a control pressure at an outlet 10 which is in permanent communication with a supply conduit 26 through a restricted choke 25. The valve member is engaged by a cantilever leaf spring 14 which is variably loaded at its free end to determine the control pressure. As shown, the loading is applied electromagnetically through a coil 18 carried by the spring and co-operating with a magnet 20. The loading will normally be arranged to increase with energization of the coil but may be arranged to increase with re-energization. The loading may alternatively be through a hand or foot lever compressing a spring which engages the leaf spring. Fluid is supplied through an inlet 40 and a regulating valve 29 operated by a diaphragm 32 to maintain a constant pressure in the conduit 26. To prevent loss of fluid through the exhaust port 7 under idling conditions, an additional valve supplying the inlet 40 may be arranged to open when the valve member 13 moves toward the port 7. In a modification, the adjustable sleeve 4 which carries the exhaust seat 7 is enlarged and houses a pressure-responsive exhaust cut-off valve (52, 53), Fig. 2 (not shown), which closes on loss of pressure in the conduit 26. In another modification, intended for a tractor-trailer braking system, an emergency loading means (A), Fig. 3 (not shown), is provided for the leaf spring 14. This consists of a solenoidoperated plunger (C) which moves to engage the leaf spring when the solenoid is de-energized in the event of a breakaway of the trailer.

Title: Improvements in machines for pressing, shaping and cutting tablets of plastic material
IPC: C11D13/00
Filed: 1935-11-29
Abstract: 455,781. Extruding and cutting soap &c. SAFA SOAP CO., Ltd., and THOMSON, J. D., Mellor Street, Radcliffe, Lancashire. Nov. 29, 1935, No. 31462/34. [Class 87 (ii)] Relates to a machine for pressing, shaping, and cutting predetermined lengths or tablets of soap or other plastic material, of the type in which the material is extruded through a nozzle against a movable plate which forms or operates the controlling member of a switch in circuit with an electromagnet the energizing of which releases a catch or stop normally preventing the operation of a cutting device and permits the latter to descend vertically to sever a predetermined length of material extruded through the nozzle. The invention consists in a particular arrangement of cam means for operating the cutting device and is shown as applied to a machine with a discontinuous screw blade c and two nozzles A arranged side-by-side in a thermostatically controlled hot water bath D with a pivoted plate a to equalize the discharge through the nozzles. The material issuing from the nozzles pushes against a plate E and forces it into contact with a plate E<1> from which it is normally separated by means of a spring. Contact of the plates closes the circuit of an electromagnet G<1> which lifts a lever H and releases a catch h from engagement with an arm k on a cam shaft K driven by chain sprocket, and friction gearing from a continuously rotating shaft K<4>. As the shaft K makes one revolution, a cam thereon causes a lever N<1> to push a rod p on which the cutter L is carried longitudinally towards the nozzles A, and a second cam by rotating allows a spring to oscillate the cutter so that a wire held therein makes a cutting stroke to sever the extruded material. A third cam on the shaft k turns a shaft e<2>, on an arm e<1> of which the plates E, E<1>, are carried, so that the plates are withdrawn to release the severed portion which falls on to a conveyer G. On completion of the revolution of the shaft K the several parts have returned to their original position. The lever H can be raised by a hand lever H<2> if desired.

Abstract: 1460979 Testing ignition circuits of IC engines BANZAI JIDOSHA CO Ltd 16 July 1974 [21 July 1973 24 May 1974 (2)] 31469/74 Heading G1U A method of testing the ignition circuit of an I.C. engine of the type in which an ignition waveform, for example the potential across the distributer points or the plug potential, is displayed, for example on a cathode ray tube screen, is characterized in that a prestored reference waveform produced by an engine known either to be good or to possess a particular fault, is also displayed in close proximity to the display from the engine under test, whereby a test engineer can more easily recognize and identify faults in the engine under test. Several possible arrangements of apparatus for performing the method are outlined. These amount, in principle, to storing the reference waveforms either on magnetic tape and reproducing them on a c.r.t., or on film and reproducing them optically and then arranging either for the waveform under examination and a reference waveform to be produced alternately on a c.r.t., or for the  two waveforms to be projected optically and superimposed upon each other on a ground glass screen.

Abstract: 377,535. Valve generating circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, London. -(Assignees of Salzberg, B. ; Rocky Point, Long Island, New York, U.S.A.) Nov. 13, 1931, No. 31513. Convention date, Nov. 14, 1930. [Class 40 (v).] In an ultra-short wave oscillator system, undesired parasitic oscillations are eliminated by making the effective electrical lengths of the cathode leads equal to an odd number of half wave-lengths at the parasitic frequency. Fig. 1 shows a known short wave oscillator circuit subject to parasitic oscillations in the leads 6. According to the invention the electrical length of the leads 6 is made an odd number of half wave-lengths of the parasitic frequency as shown in Fig. 3. To reduce the physical length, chokes may be inserted in the leads Fig. 4, (not shown) or tuned circuits resonant at the parasitic frequency Fig. 5, (not shown). To prevent any alteration of the cathode circuit characteristics due to supply leads 38, the latter are connected to the cathode circuit at voltage nodal points 40, 42 or 44, as shown in Fig. 6. The line 38 is made an odd number of quarter wave-lengths long at the parasitic frequency, the effects of the condensers 26 being allowed for in estimating the electrical lengths. For parallel-connected valve arrangements the filament leads to each valve should be equal in length or should differ by one whole wave-length at the parasitic frequency, the length of the filament supply leads being an odd number of quarter wavelengths, as for Fig. 6, Fig. 7 (not shown).
