Title: Improvements in and relating to regenerative heat exchangers
Inventor: ELLIOTT DOUGLAS ERNEST
IPC: F28D11/02
Filed: 1954-07-29
Abstract: 791,160. Pulverized fuel-fired combustion apparatus; gasifying coal. POWER JETS (RESEARCH & DEVELOPMENT), Ltd. July 18, 1955 [July 29, 1954], No. 22153/54. Classes 51 (1) and 55 (1). [Also in Group XIII] A regenerative heatexchanger for gases has a rotary wall 1a which defines a duct for the gases and is shaped to retain a thick layer of a partly molten mass s inside the duct and bounding the gas path. The wall is driven by an electric motor 8 at such a speed as to provide the centrifugal force necessary for building up and maintaining the layer. End walls 1b, 1c help to maintain the mass, which may be slag from the combustion of powdered fuel supplied to nozzles 15a. The outer layers of slag, in contact with the wall 1a, is solid and much cooler than the molten inner layer. The slag overflows through a notch in the end wall 1c into a water trough 12. The rotary wall is mounted on ballbearings 5 and has labyrinth seals 9. Cooling air is passed through a jacket space 4a by an inlet 13 and outlet 14. Valves 16-19 control the flow of gases through the duct formed by the rotary wall. A gas to be heated, e.g. a mixture of oxygen and steam, is supplied from the pipe 20 to one end of the duct and is heated by the molten material. In the central zone 3 of the duct it takes part in an exothermic reaction with powdered coal from the nozzles 15a. The hot gases evolved, hydrogen, carbon monoxide, carbon dioxide, and steam, heat the other end of the duct before passing to the pipe 21. When the valves 16-19 are reversed the flow through the duct is in the opposite direction. According to the Provisional Specification, the wall may be rotated by the action of the incoming or outgoing gas on vanes or blades attached to the rotor and the reaction chamber at the centre of the duct may have a wall which is separate from and rotates faster than the walls of the rest of the duct. Specification 784,745 is referred to.

Abstract: 749,273. Extra-air valves. VAYNE, L. June 15, 1955, No. 22327/53. Class 7(2) In a supplementary air valve comprising a casing 1, 4, open at one end through inlets 5 to the atmosphere and open at the other end 2 to an engine induction manifold, a seating 8 with apertures 9 therein movably disposed in the casing, and a disc 10 biased by a spring 12 against the seating 8 under the influence of a reduced pressure in the manifold to permit air flow through the casing, the seating 8 is displaceable against the action of a spring 11 to uncover openings 4a in the side of the casing to relieve excess pressure in the manifold. The inlets 5 are inclined and the apertures 9 are tangentially arranged whilst the disc 10 and seating 8 are supported on a rod 7; the air follows the path indicated by the arrows and is given a helical movement by the apertures 9. The relative loading of the springs is dependent upon the extent to which the casing parts 1 and 4 are threaded into each other and the length of the rod 7 within the casing.

Title: Improvements in or relating to gear-controlling means for automobile vehicles, more particularly motor cycles
IPC: B62M25/04
Filed: 1935-08-09
Abstract: 448,160. Controlling variable-speed gearing. AUTO UNION AKT.-GES., 110, Scheffelstrasse, Chemnitz, Germany. Aug. 9, 1935, Nos. 22501 and 22502. Convention dates, Aug. 10, 1934 and Feb. 1, 1935. [Class 80 (ii)] [See also Group XXXI] The gears on a motor-cycle or other motor vehicle are changed by means of a pedal 1 and a hand lever 6 coupled together. In the construction shown, the gear-lever 4 is connected by a link 9 to the hand lever 6, and by a link 5 to a lever 3 operated by the pedal 1. The pedal control may be of the kind shown in Fig. 2 in which each stroke of the pedal changes the gear one step up or down, and the pedal, when in the released position shown, may be disconnected from the lever 3 so that the pedal always operates the hand lever as well as the gear lever, but the hand lever does not move the pedal. The gear ratio which is engaged at any time is thus indicated by the position of the hand lever 6 in its quadrant 8. The pedal 1 is fixed to a disc 14 rotating on a pin 17 and carrying pawls 10 pivoted at 13 on the disc and adapted to engage teeth 11 on a rotary member 12 fixed to the lever 3. In the released position of the pedal the pawls, which are controlled by springs 15, are held out of engagement with the teeth 11 by stops 16. Each time the pedal is depressed from the central position shown the lower pawl 10 engages a notch 11 and rotates the lever 3 from one gear position to the next gear " down " ; when the pedal is lifted from the central position the upper pawl engages a notch and rotates lever 3 to the next " up " gear position. In a modification, the pawls 10 are both engaged with notches 11 when the pedal is released.

Filed: 1923-09-13
Abstract: 204,695. Corblin, H. Sept. 29, 1922, [Convention date]. Flexible diaphragm pumps.-In an air pump in which compression is effected by a diaphragm oscillating in a chamber formed between two discs one of which is formed with inlet and outlet valves, the diaphragm is oscillated by a pump piston acting on a body of liquid, the displacement of the piston being less than that of the compression chamber, and the additional liquid necessary to secure complete compression being supplied below the piston by an auxiliary pump driven from the same crankshaft as the main pump and supplied with liquid which may have leaked past the main piston or have flowed through a relief valve therein. The piston h causes a liquid, for example, oil, to flow to and fro above the compression diaphragm c through openings b<1> in the upper disc of the compression space. Liquid leaks past the piston, or, if the pressure rises unduly, passes out through the valve h<1> therein, to a tank k from which it is withdrawn through a cooler n by a pump l which forces it into the space below the piston h. Specification 166,127 is referred to.
