IPC: E02D7/30
Filed: 1953-12-30
Abstract: 728,211. Piles. FRANKI FOUNDATION CO. Dec. 30, 1953, No. 36162/53. Class 68(2) In an expansible mandrel for driving  sheet metal tubes into the ground, having a central member 12 and sectors 3 in which pneumatically controlled expansion chambers provide a radial thrust to support the tubes during driving, a separate set of pneumatic chambers is provided for the contraction of the mandrel. Preferably, each chamber is a longitudinally extending rubber pipe, each pipe 19 of one set being in radial alignment with a pipe 18 of the other set. The pipes are closed at their lower ends, and the admission of fluid under pressure to pipes 19 forces the arms 17 and 11 apart, contracts the mandrel, and flattens pipes 18 against their resilient tendency to assume a circular form. On inflating pipes 18, pipes 19 offer no resistance to flattening and the sectors 3 are guided radially outwards by arms 9. Upper casing 6 is attached by bolts 7 which allow for the radial movement of the sectors 3, and is provided with a wooden block 24 to receive hammer blows. These are transmitted to the central member 12 through resilient washer 15. Lugs 25 are provided for the with-, drawal of the mandrel, after which the tube 1 which may be conical or have a smooth wall, is filled with concrete or like. The lower end of the tube may be covered by a plate 2 of metal or concrete or may be sealed with a plug of concrete.

Title: Mixing apparatus
Inventor: HAYES RAYMOND
IPC: B29B7/40
Filed: 1958-11-12
Abstract: 863,843. Mixing appliances. IMPERIAL CHEMICAL INDUSTRIES Ltd. Nov. 6, 1959 [Nov. 12, 1958], No. 36334/58. Class 86 A portable continuous mixing apparatus especially for the production of polyurethane foams has a manually operated valve controlling material input which is arranged to admit also a supply of compressed air to blow through and clean the apparatus after use. The mixing chamber 1 has pegs 6 fixed to the inside and similar pegs 5 attached to a rotatable shaft 4 driven from a power unit 12 (which may be an electric or compressed air portable tool) through an intermediate shaft 10. The shaft 10 passes through a valve consisting of two fixed blocks 7, 9 with an interposed rotatably movable block 8. Each block has a pair of ports which may be placed in register by suitable positioning of the block 8. Polyisocyanate is supplied by a conduit 18 to a point 17 in block 9 and then through passages 25 in block 8 and 23 in block 7 to the mixing chamber. Similarly a polyester is supplied through conduit 20 and passages 26, 24. A third conduit 22 supplies compressed air through the block 9 to an annular recess 27 surrounding the shaft 10 and thence to a passage and port 29 in block 8. When mixing is interrupted the block 8 may be rotated to bring the port 29 into coincidence with passage 24 and thus admit compressed air into the mixing chamber. The intermediate shaft 10 is connected to the power source and the shaft 4 by detachable couplings 11, 13. A scraper blade is provided for the face of the block 7 at 32. Lugs 30, 31 are provided on the blocks 7, 8, 9 to facilitate alignment. The port 26 for the polyester may conventiently be made kidney shaped as shown, Fig. 3, in order to give the more viscous liquid a "lead" so that it has time to reach the mixing chamber before the arrival of the more mobile liquid. A passage 33 in the shaft 10 may provide an air bleed to the mixing chamber during mixing. In a preferred embodiment, Figs. 5 to 8 (not shown), the apparatus is made shorter and more easily portable by empolying only one fixed and one movable valve block; and an adjustable air bleed enables the amount of air admitted during mixing to be controlled.

Title: Master cylinder for hydraulic fluid pressure systems
Inventor: WILSON ALEXANDER JOHN
IPC: B60T11/20
Filed: 1961-10-12
Abstract: 967,218. Hydraulic brakes. GIRLING Ltd. Oct. 4, 1962 [Oct. 12, 1961], No. 36606/61. Heading F2F. A master cylinder 1 for hydraulic fluid pressure systems includes within the working space 5 of the cylinder a channel 21 which is in alignment with the outlet 7 of the cylinder and which is in communication with the outlet and with the main part of the working space into which a piston 2 moves to displace fluid from the cylinder, the channel being positioned so that air or any other gases trapped in the working space will be collected in the passage and will, during bleeding of a system to which the cylinder is connected, be carried along the passage to the outlet. The channel 21 is annular and is defined by a neck 20 formed in a liner 18 located in the space 5 so that the outlet 7 communicates with the channel 21 and not directly with the main part of the space 5, whereby, when the piston 2 is advanced (to the right as shown in the Figure) to displace fluid from the space 5 through the system and, with it, any bubbles of air present (a nipple or cock being opened at a suitable point in the hydraulic system during the bleeding operation) the fluid, instead of passing straight out through the outlet 7 and so leaving air bubbles trapped in the space 5, flows at least part of the way round the annular channel 21 and through an opening 22 at the top of the neck 20, so producing effective scavenging and removing any trapped bubbles of air. A tandem master cylinder is shown in Fig. 1, the outlet 7 from the cylinder space 5 being connected to the front (or rear) brakes of a vehicle and an outlet 8 from a cylinder space 6 being connected to the rear (or front) brakes. The piston 4 in the cylinder space 6 is floating, i.e. it is connected with, but not firmly attached to, an extension from the piston 2 into its hollow rear end. Valves 15, 16 lead to an hydraulic fluid reservoir. On application of the brake the main piston 2 is advanced (to the right) by a pedal-operated push-rod which enters a recess 3 in the piston and the floating piston 4 also advances, assisted by a spring 17, and a flange 13 thereon moves away from the stem of the spring-loaded valve 15 and allows the valve to close, causing pressure to build up in the space 5. This causes the floating piston 4 to advance further and allow the valve 16 to close, so building up pressure in the space 6.

Abstract: 1,240,880. Brushless motors. AKAI ELECTRIC CO. Ltd. 6 Aug., 1968 [8 Aug., 1967], No. 37404/68. Heading H2A. Star-connected phase windings L1, L2, L3 forming the stator of a permanent magnet rotor motor are energized from a D.C. supply through transistors Tr2, Tr4, Tr6 which are connected in a ring oscillator circuit 10, supplied through voltage and current control circuits 12, 11, and are rendered conducting by the voltage induced in successive windings. Each stage of the oscillator comprises two directly coupled transistors Tr3, Tr4 having the collector of Tr4 connected to phase winding L2. The input to the stage is coupled to the output of the previous stage through capacitor C1 and integrating circuit R4, C4 and similarly for the other stages. In operation the voltage across resistor R10 will alter with supply fluctuations and this voltage will be transmitted to base of transistor TR7 through VR and will set a voltage at one end of Zener diode ZD. Voltages at the ends of the phase windings will be rectified by diodes D1, D2, D3 and are applied to the other end of ZD and can thereby produce a current flow in resistor R10 thus causing the conductive state of TR8 to change. This charge in voltage will also occur when rotor speed changes and thus the circuits 11 and 12 act to maintain a constant rotor speed. The speed of the motor is varied by altering VR and switch SW2 is used to by-pass the current control circuit 11 so that a higher speed can be obtained.
