Title: Improvements in and relating to electric switching devices for train lighting, heating, and like installations
IPC: H02J7/14
Filed: 1933-07-10
Abstract: 424,128. Electromagnetic switches. STONE & CO., Ltd., J., Deptford, and NIXON, L. R., 742A, Sidcup Road, New Eltham, both in London. July 10, 1933, No. 19547. [Class 38 (v)] A change-over switching device operable by electromagnetically - operated contactor switches in double-battery train-control systems such as are described in Specification 424,126 comprises a rockable change-over switch, a ratchet body connected to said switch and a pair of spring-loaded tongues each of which is adapted to be operated by its respective contactor to perform a to-andfro motion substantially tangentially to the ratchet body, slipping past the ratchet body on the in-stroke of this movement and engaging and rocking said body to change-over, or initiate change-over of the switch on the return stroke. As shown in Fig. 1 the two alternately-operable contactors 3, 4 are mounted side-by-side on an insulating base 2, the changeover switch being mounted between them. The pivoted armature arm of each contactor carries a transverse rod 43, a reduced end 44 of which, Fig. 3, engages a slot 45 in lever 31 pivoted at its lower end 38 and a carrying at right-angles to its axis at its free end a tongue 29. The tongues 29 are pivoted at 30, springs 33 being interposed between them and the arms 31 and adjustable stop screws 29<1> limiting their rotation under spring action. Thus as the arms 31 are swung backwards and forwards during the operation of their respective contactors the spring tongues 29 perform a to-and-fro motion substantially tangentially to a ratchet body 14 pivoted at 15, the tongue 29 engaging a pin 16 or 17 during the outward movement of the corresponding pivoted arm 31 and slipping past the corresponding pin during the inward movement. Thus the alternate operations of the contactors 3, 4 swings the body 14 in opposite directions bringing a dead-centre mechanism across the line of centres and ensuring a change-over movement of a double-ended movable contact 7 attached to the body 14 with a snap action. The dead centre spring 21 extends between a pin 20 on an extended projection of the ratchet body and a pin 23 on an arm 24 pivoted at 25 and having a forked end engaging a pin 26 on the ratchet body. Current is led to the movable contact 7 of the change-over switch by a flexible lead 71, the contact engaging a fixed contact 10 or 11 in its opposite extreme positions to effect the change-over of the battery connection. The contactors 3, 4 are constructed in the manner described in Specification 424,127. If desired, the operating rods 43 may be disengaged from the arms 31 by withdrawing them manually against springs 46 so that the change-over mechanism may be temporarily put out of action.
Patent GB-970591-A (GB)
Title: Improvements in or relating to the manufacture of graphite
Inventor: PRICE MICHAEL STUART THOMAS
Filed: 1961-05-30
Abstract: Graphite is made from a three component grist of coarse artificial graphite, fine artificial graphite and carbon black, admixed with a carbonisable binder to form a green compact, which is carbonised and graphitised.  The components of the grist are coarse artificial graphite of particle size in the range 50-250 microns, 10 to 30% by weight of fine artificial graphite of particle size less than 25 microns, and 25 to 40% by weight of carbon black.  The particle size of the carbon black may be 0.4 microns, but a proportion of carbon black in the grist may have a particle size of 0.02 microns.  The resulting manufactured article may have open pores in the size range of 0.6 to 0.8 microns diameter. In an example, grist components are admixed and a binder e.g. Ford's pitch is added in 20 to 26% by weight of the total.  The mixture is cold and hot mixed, transferred to a hot extrusion press where, after evacuation to remove entrained gases, it is extruded through a 2 inch diameter die at 1 foot/min. at 120 DEG  C. The green compacts, when cooled, are packed into metal tubes in which they are supported by a 3/16 inch lining of medium-size coke packing grist.  Heating is effected under constant pneumatic pressure of 100 p.s.i.g. in a reducing or neutral atmosphere at a rate of 3 DEG  C. per hour to 550 DEG  C., this temperature being held for 4 hours.  The compacts are then fully carbonized by heating at atmospheric pressure to 900 DEG  C. and maintaining at that temperature for 4 hours.  Graphitization is effected by reheating the carbonized compacts to 2700 DEG  C. and holding at this temperature for 30 minutes.  Figures to Specification compare the physical properties e.g. pore size and porosity, of compacts with different graphite compositions. Specification 901,847 is referred to.

Filed: 1964-05-14
Abstract: 1,056,486. Valves. L. REXROTH. May 14, 1964 [May 21, 1963], No. 20039/64. Heading F2V. A valve comprises a longitudinally movable hollow piston 41, not shown, which in its central position divides the flow through the inlet 16 into partial flows, which flow through the piston in two different directions. The piston 41 comprises a transverse wall 48 separating two chambers 44 and 45 respectively connecting with bores 52, 53 and 54, 55. The valve body 1 comprises chambers 4 and 8 connected to a reservoir outlet 17, chambers 5 and 7, each respectively connected to consumer ports 14 and 15, and a chamber 6 connected to a pump inlet 16. In the central position shown, flow from the inlet 16 divides equally through bores 53 and 54, chambers 44 and 45, bores 52 and 55, chambers 4 and 8 which connect with the outlet 17. Movement of the piston 41 to the left divides the flow from inlet 16 between a passageway comprises through ports 54, chamber 45 and bore 55, and a passageway formed by an annular groove 58 around the piston 41, both passageways connecting with the outlet 15. Movement of the piston to the right similarly connects the inlet 16 with the outlet 14. The piston 41 is moved by fluid pressure from the pump 32 admitted to the chambers 28 and 29, under the control of a valve 25. Movement of the valve 25 to the left or right effects a similar movement of the valve 41. Fluid in the chamber 28 or 29 acts on a piston 61 or 67, which is axially movable in the piston 41 to move the piston 41 until a flange 62 abuts a stop surface 63, whereupon pressure is transmitted through the openings 64 to act on the end face of the piston 41 and effect further movement. Valve 25 also connects the retracting chamber 28 or 29 to a reservoir 11. Adjustable throttles 37 and 38 are disposed in lines 22 and 23 respectively.

Title: Circuit arrangement for generating a sawtooth current
IPC: H03K4/83
Filed: 1972-05-01
Abstract: 1387617 Line time base circuits PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 1 May 1972 [4 May 1971] 20104/72 Heading H3T [Also in Division H2] The invention relates to a line time-base circuit of the type comprising a first bidirectional switching device 15 coupled to the deflection coils 22 to pass deflection current during the second part of the scan and a second switching device 12 coupled to the first through a series resonant circuit 7, 8 which device serves to terminate the scan and also comprising a supply inductor 3 connected between the switch 12 and the supply. According to the invention this inductor together with the resonant circuit 7, 8 resonates at a frequency lower than the scanning frequency but higher than half this frequency. The requirements of the switch 12 are thus eased. During the first part of the scan current flows from the deflection circuit 18 through diode 14 and thereafter reverses and flows through thyristor 13. Towards the end of the scan a thyristor 12 is fired and a relatively high-frequency circuit 7, 8 rings around a path including thyristors 12 and 13 and when the reverse ringing current exceeds the forward current through thyristor 13 the latter is quenched but deflection current continues through diode 14 until the ringing current rises and then falls to equal the reverse deflection current whereupon the diode cuts off. Resonant reversal of the deflection current now takes place via capacitor 16 whereafter the scan current recommences via diode 14. The ringing current from 7, 8 eventually reverses and becomes equal and opposite to the current flowing in thyristor 12 from inductor 3 whereupon the thyristor 12 extinguishes. Capacitor 7 now discharges through inductors 3 and 8 the resonant frequency of this circuit being between 0À5 and 0À8 of the line frequency, reverses its polarity and recharges the capacitor. Pulses for controlling thyristor 12 are received by an amplifier 26-32 and for controlling thyristor 13, from coil 33. In Fig. 3 (not shown), thyristor 13 is replaced by a transistor, reverse conduction from the collector to base serving instead of diode 14. In addition, thyristor 12 is connected to a tap on inductor 3 and the deflection coils may be connected directly across 18 and 19. An EHT voltage is available at 25.
