Abstract: 613,043. Spring suspensions for vehicles. JULIEN, M. F. A. Nov. 14, 1945, No. 30466. Convention date, Nov. 22, 1944. [Class 108 (ii)] In an anti-roll device for vehicles, the two wheels of a pair are connected together by an axle capable of undergoing torsion, the axle being connected to the vehicle by articulations arranged so that vertical displacement of a wheel subjects the axle to torsion which thus exerts an anti-rolling action. The articulations preferably consist of a system of linked arms forming an irregular quadrilateral, one arm being fixed to the axle. As shown, the tubular axle 2 is suspended by arms 1 and torsion members comprising a torsion tube 5 mounted in bearings 17, 18 and torsion bar 4 connected to the tube 5 at 16 and anchored to the chassis frame at 14, as described in Specification 602,065. Rigid with the axle 2 are vertical arms 7 articulated to arms 6 pivoted at B to a bracket 9 fixed with the frame. Vertical displacement of either wheel result in the corresponding arms 7 and hence the axle being twisted, the amount of twist increasing quickly with increasing amplitude of displacement. The joints B, D, E are preferably resilient. A stabilizing transverse rod 11 may be provided, one end being secured to one end of the axis and the other end being secured to the chassie frame.

Title: Improvements in float operated valves
Inventor: COLLIVER HAROLD EDWARD SYDNEY
IPC: G05D9/02
Filed: 1955-10-25
Abstract: 847,366. Valves. S.P.E. CO. Ltd. Oct. 25, 1956 [Oct. 25, 1955], No. 30534/55. Class 135. A float operated valve for controlling the level of fuel in a tank is characterised in that the plane of pivotal movement of the float is maintained upright regardless of the attitude of the aircraft and that the reverse action of the float is over-ruled if the aircraft is inverted or subjected to negative " g." The float 40 is pivoted about the axis of a rotary pilot valve 35 by means of two arms 38, such that movement of the float rotates the valve. A weight 31 is likewise pivoted about the axis of a second rotary pilot valve 26. Both pilot valves are housed in the arm 24 of a hollow spindle 22, free to rotate within a tubular pillar 21. The main valve 12 is attached to a diaphragm 13 which forms the lower wall of a chamber 14, open to inlet pressure through a duct 17. The lower end of the hollow spindle 22 communicates with the chamber 14 forming an outlet passage, controlled by the two pilot valves 26 and 35 respectively. With the valve as shown the outlet from chamber 14 is open. Under these conditions fuel pressure at the inlet 10 can open the valve 12. When the tank becomes full the float 40 rises and by rotating the pilot valve 35 closes the outlet from chamber 14. Fuel entering the chamber 14 by the duct 17 then builds up pressure causing the main valve to close. Should the aircraft be inverted or subjected to negative " g " the weight 31 will move to cause the second pilot valve 26 to close the outlet from the chamber 14 over-ruling the action of the float, which will open the valve 35. If the plane of pivotal movement of the float and weight tends to move from the upright attitude the arm 24 under the influence of the weight 31 and the buoyancy of the float will rotate about the pillar 21 to restore the plane to an upright attitude.

Abstract: 813,043. Fluid-pressure servomotor control systems. FLUIDRIVE PATENTS Ltd. Sept. 7, 1955 [Oct. 25, 1954], No. 30739/54. Class 135. To regulate the torque transmitted by a hydraulic turbo coupling comprising vaned impeller and runner elements and an adjustable scoop tube 2, the position of the scoop tube is adjusted by an hydraulic servomotor 13 powered by pressure liquid withdrawn from the scoop tube and controlled by a valve 15. The inlet of the valve 15 is connected by a line 14 to a duct 1 which receives liquid from the scoop tube outlet and transfers it through a pipe 6 and a cooler 5 to a duct 7 connected to the coupling inlet. A spring-loaded valve 18 restricts flow into the pipe 6 so that normally all the liquid passes through the cooler. The valve 18 is connected to a piston 19 subjected to the pressure in the right-hand end of the servomotor cylinder so that when pressure liquid is admitted to this end to withdraw the scoop increased pressure is produced in the line 14 to operate the servomotor piston 12. In the lowering of the scoop increased pressure. results in the deeper engagement of the scoop tip in the liquid in the coupling and to avoid an unduly fast rate of scoop movement the port, not shown, leading to the left-hand end of the cylinder is suitably restricted. The valve 15 comprises a spool 16 operable by a hand lever 24 and slidable in a follow-up sleeve 16a connected by a link 21 to a lever 8 to which the servomotor piston 12 and the scoop tube 2 are connected. An extension 23 of the lever 8 may be provided to set the scoop tube position when the coupling is inoperative and liquid under pressure is not being supplied to the servomotor. Specifications 493,703 and 767,936 are referred to.

Filed: 1966-07-08
Abstract: 1,092,986. Magnetic storage devices. INTERNATIONAL BUSINESS MACHINES CORPORATION. July 8, 1966 [July 9, 1965], No. 30821/66. Heading H1T. [Also in Division H3] A magnetic memory device incorporates a thin film of a magnetic material with rotational initial susceptibility properties such that an easy axis may be produced in any direction by application in that direction of a field in excess of the coercive field and changed to a new direction by the application of a further similar field in the new direction. Binary storage is achieved using two remanent magnetic states of this sort separated by a small angle, one being produced by a field due to a unidirectional pulse in a conductor and the other by a combination of such a field with a smaller field produced by a current in a second conductor at right angles to the first. Readout is accomplished by energizing the first conductor. If an " O " has been written in by a pulse in the first conductor alone there is no output, but if the remanent state of the film is at an angle to that produced by the first conductor a pulse in excess of that required to exceed the coercive force for the film results in an output in the second conductor or in a separate sense conductor and so in a destructive read-out. Film elements of this kind may be arranged in an array (Fig. 3, not shown), or be constituted by parts of a continuous sheet traversed by conductors (Fig. 4, not shown). The small angles between the two remanent magnetic states make possible high-speed operation by rotational switching, not domain wall switching, and it is stated that a memory composed of elements of this kind may be used in high-speed computer applications.

A fuel fired or waste heat steam or hot water return tube boiler 1 includes a flue 2 connected to a wet back chamber 3 from which a first pass of return tubes 4 extends to a smoke box 5. A second pass of return tubes 6, 7, 8 extends rearwardly from the smoke box 5 to a chimney 9. The tubes 6 are fitted with full length retarders, the tubes 7 with half-length retarders, and the tubes 8 are left unretarded. Water is supplied to the base of the boiler through one or more distributer pipes 10 having downward distribution slots 13 at their ends, or arranged at intervals along their length. Due to the preponderance of retarders in the uppermost return tubes 6, and the fact that the cold water supply is fed into the bottom of the boiler, the rate of gas flow varies from a minimum through the tubes 6 in the hottest water to a maximum through the tubes 8 in the coldest water. Tubes fitted with flow restricting orifices or nozzles may be used in place of the retarde rs of differing lengths.
