The toy track crossing described in the parent Specification is modified in that the main track 1 is provided with control and restoring members 9, 9a such that a projecting arm of a vehicle approaching the crossing from either direction along track 1 strikes one of the members 9, 9a and causes a brake-actuating platform 22 on track 2 to be lowered and the brake of a vehicle approaching the crossing along track 2 to be operated. The members 9, 9a are interconnected by a pivoted member 16 which operates the platform'22 by means of a link 18 and a cranked rod 19. As the first vehicle leaves the crossing it strikes the other member 9 or 9a and the platform is restored to its original position thus releasing the brake on the second vehicle. Track 1 may be printed or embossed to represent rail track, and track 2 a roadway, appropriate types of vehicle being provided. A second braking platform may be arranged on track 2 to permit vehicles to run in either direction on this track. Tracks may be built up to incorporate more than one crossing and indentations 8 may be provided to allow of separate sections.

Abstract: 1,074,166. Reciprocating pumps and motors. CESSNA AIRCRAFT CO. June 1, 1965, No.23373/65. Heading F1A. To prevent shock when the cylinders of an axial or radial cylinder pump or motor are moving relative to a bridge between the low pressure port 41 and the high pressure port 42 in the ported valve block, plate 40 or pintle, the cylinders communicate with a cylinder pressure regulating chamber 48 having a piston 51 or diaphragm subject to the pressure in the port 42. The chamber 48 provides means whereby the pressures in the cylinders are substantially equalized with the pressure in port 42 immediately prior to communication with the port. If the pressure is higher in the respective cylinder than the port 42 liquid flows into chamber portion 52, which liquid is returned to the port when the cylinder bridges the port and port 46. To provide for the cylinder pressure being less than the port pressure a restricted passage (57), Fig. 6 (not shown) or (58), Fig. 7 (not shown), may be provided to give a direct connection between the high pressure duct (21) and the pressure regulating chamber portion (52) inwardly of the pressure regulating chamber piston. In the embodiment illustrated in Fig. 9 (not shown), an elastic diaphragm 71 is mounted between stops (74, 75) for movement inwardly and outwardly relative to the cylinders. A pair of ports (60 and 61), Fig. 8 (not shown) may provide communication between the pressure regulating chamber and the cylinders. To provide for reverse cam plate inclination in an axial cylinder pump or motor, a pair of pressure regulating chambers are provided (47, 48), Fig. 5 (not shown). A piston valve (84), Fig. 12 (not shown), may be provided to connect the pressure regulating chamber to the duct (20 or 21) in which the high pressure exists to allow for reversal of direction of the pump or motor. In the embodiment illustrated in Fig. 14 (not shown), a radial cylinder pump or motor is provided with a pressure regulating chamber in the pintle (101).

Abstract: 717,590. Gas turbine plant. DOWTY EQUIPMENT, Ltd., and SIMMONS, H. C. Oct. 10, 1952 [Oct. 11, 1951], No. 23733/51. Class 110(3) [Also in Group XI] In a gas turbine fuel system comprising two pumps, one of which, a circulating pump, circulates fuel around a circuit including the swirl chambers of spill type burners and the other, a supply pump, supplies controlled quantities of fuel to the circuit, the circuit comprises a plurality of spill burners 15 each having an inlet connected through a non-return valve 23 to a common burner ring 13 and a spill orifice connected through a non-return valve 25 to a common collector ring 17, an engine driven centrifugal or other non-positivedisplacement type pump 11 having its inlet connected to the collector ring and its outlet to the burner ring through a shut off cock 24 and a branch line connected to the supply pump. The non-return valves 23, 25 may be incorporated in the burners. The engine driven supply pump 19 injects fuel from the supply tank 20 into the circuit at the inlet of the circulating pump 11. The rate at which fuel is injected is regulated by a manually operated unit 21 and by-pass valve 22. A diversion cock 27 may be used to direct fuel from the pump 19 either to the circuit or to a by-pass 28 leading back to the suction of the pump 19. The cocks 24, 27 may be ganged together so that when cock 24 is closed, cock 27 diverts the fuel back to the suction of the pump. The cock 27 may be included in the circulating pump circuit in which case the circuit will have two connections with the supply, one with the delivery of the pump 19 and one with the return passage 28. If the pump 11 fails, the valves 25. will close and the burners will then operate as direct injection nozzles. The supply pump system may include controls responsive to engine speed, ambient air conditions and acceleration.

Title: A multiple spot welding machine
IPC: B23K11/31
Filed: 1959-07-10
Abstract: 867,815. Welding by pressure. SCHLATTER A.G., H. A. July 10, 1959 [July 14, 1958], No. 23776/59. Class 83 (4). In a multiple spot-welding machine one electrode of each pair is moved by an hydraulic ram, and is also cooled by the hydraulic fluid. The electrode 10 is mounted in a holder 3 which slides in a body 1 and is connected to a piston 5 by a rod 12. There is a stop 15 on the upper face of the piston. Coolant passes through a duct 16 in the holder 3, to a bush 11 and thence to a flexible discharge pipe 35. This pipe contains a metal screen 36 which conducts current from one pole of the welding current source to the electrode. A control element comprising a plunger 8, biased by a spring 18 slides in a cylinder 7, and a passage 19 passes through the plunger which communicates with a fluid inlet 23. In the rest condition the pressure of the fluid is not sufficient to displace the plunger from the position shown in the Figure, the fluid fills the spaces 22, 24 and 26 and the piston is held at the top of the cylinder. To displace the electrode the fluid pressure is increased so that the difference in load on the faces 20 and 21 moves the plunger against the spring 18 until the cone 29 seats on the edge 37. In this position fluid-pressure is applied to both faces but due to their different effective areas the piston moves down. The quantity of cooling fluid available for each weld is determined by the swept volume above the piston, but this quantity can be increased by, for example, an additional passage between the space 22 and the duct 16.

Filed: 1937-09-01
Abstract: 497,865. Valve generating circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. Sept. 1, 1937, No. 23928. Convention date, Sept. 10, 1936. [Class 40 (v)] In a method of generating oscillations of constant frequency, from the generated oscillations secondary oscillations are produced which are rectified and then converted into unidirectional pulses which are fed back to sustain oscillation. Oscillation is started in circuit 15, Fig. 1, by passing a momentary current through valve 14 whose grid is normally biassed below cut-off. The oscillating potential, Fig. 2, is passed through phase-shifting means 21, 19, an amplifier 20 and filter 22 so as to produce across resistance 4 a pure sine wave, Fig. 3, 90‹ out of phase with Fig. 2. A current then flows through anode 2 of the double diode triode 1 and the resultant voltage drop across 7 causes the bias of the grid 5 to drop below cut-off. As the wave across 4 passes through zero the charge on condenser 11 maintains a current flow through the resistance 7 so that the bias of the grid 5 cannot rise enough to allow valve 1 to pass a current. The second half of the wave passes current from anode 3 causing further current flow through the resistance 7 and the complete discharge of condenser 11. The bias of the grid 5 consequently drops again and finally rises to zero as the curve in Fig. 3 passes through zero. Thus the grid bias of valve 1 only rises to zero once per cycle, Fig. 4, and in doing so allows momentary pulses to fiow through its-plate circuit, at the same instant that the oscillations in 15 are at their maximum, Fig. 5. These pulses are passed to the grid of valve 14 so raising its bias above cut-off and allowing a pulse to pass to the tuned circuit 15 to maintain oscillation. Oscillation is started by closing switch 9 and output is taken at 25.
