Title: Self-servo braking systems
IPC: F16D65/18
Filed: 1970-07-04
Abstract: 1352833 Combined drum-and-disc brakes; self-servo operation; rotating shoes GIRLING Ltd 2 July 1971 [4 July 1970 10 March 1971] 32528/70 and 6444/71 Heading F2E The invention relates to braking systems of the kind comprising primary and secondary pairs of co-operating friction elements of which one element is common to both pairs, and frictional engagement of one pair produces frictional engagement of the other pair. In Figs. 1 and 2 blocks 65 of friction material having inner faces of wedge outline are located in angularlyspaced recesses in the periphery of a carrier 66 rotating within a stationary drum. Each block is located between outwardly-cranked ends 69, 70, of strips 71 72, frictionally slidable in sleeves on the outer ends of spring members 73, 74, extending through slots 75, 76, respectively in the carrier with play. The spring members are preloaded to lie against the adjacent edges of the slots, as shown. When the carrier is rotating clockwise, as shown, centrifugal force urges the block outwardly so the drag causes the block to rest against end 69 of strip 71. In operation, the blocks 65 are moved axially into engagement with a radial surface in the drum by an annular piston 77, Fig. 1. The increased drag on each block forces spring 73 against the circumferentially-outer end of slot 75, and eventually the block comes into engagement with the inclined surface 67 on the carrier by which it is forced outwardly into engagement with the drum. On release, the spring 73 returns the block so that the clearance 78 between block and carrier is re-established. Analogous actions occur in the opposite direction of rotation. In Figs. 3 and 4, (not shown), inclined articulated struts (80, 81) are substituted for the abutments 67, 68. The struts are held in engagement with abutments (82, 83) in the carrier by springs (84), and have part-spherical ends about which the friction block rocks when it is retarded by frictional engagement with the radial surface in the housing.

[Classes 83 (ii) and 83 (iv).] A reel 10 of strip metal for tube making is welded to the previous strip end at 11 and passes to a preheating furnace 12 (800‹ C.) and is bent up to open tube form in rolls 18. It then passes through another furnace 20, where it is heated to 1100‹ C. and then to 1300‹ C. and passes between guide rollers 24 to a welder 27 where the edges are heated by oxy-acetylene jets 29 to welding temperature while the side and bottom are cooled by steam or water jets 32 so that it withstands the pressure of the welding rolls 28 forcing the hot edges together to weld them. The tube then passes through sizing rolls 33, and a polishing wheel 34 and is cut off in lengths by a travelling saw 35. It may then pass to drawing reducing, grinding, polishing or expanding means. The rollers 17, bending rolls 18 and driven feed rollers 23 may be cooled. The guide roller 24, Fig. 2, has a central rib 26 to engage the space between the bent up edges of the tube and so prevent it twisting. The steam or water jets 32 may also act to descale the tube.

Title: Improvements in the constant pressure governing of turbo blowers and compressors andother turbines
IPC: F04D27/02
Filed: 1925-12-28
Abstract: 268,044. Adamson & Co., Ltd., D., and Gilmour, J. Dec. 26, 1925. Regulating. - To maintain the delivery pressure of a turbo-blower or the exhaust pressure of a backpressure turbine constant, the loading of the centrifugal governor is varied in accordance with variations in the delivery or exhaust pressure. In the case of a turbo-blower the governor is set so that the speed cannot be reduced to the surging speed and further increase in the delivery pressure is used to close the blower suction valve. The delivery or exhaust is connected to chamber A, Fig. 2, and a spring b is extended by the pressure on the piston or bellows B. Movement of the valve pistons D<1>, D<2> controls the passage of pressure oil from d to d<1> or d<2> and the consequent operation of the motor which adjusts the loading of the centrifugal governor. A similar device controls the passage of pressure oil to a cylinder and piston for operating the blower suction valve. When pressure oil passes to close this valve it is also admitted below a piston D<5> on the first device and prevents a too rapid response of that device to falling delivery pressure.

Abstract: 627,870. Impedance networks. HAZELTINE CORPORATION. Nov. 4, 1946, No. 32744. Convention date, Nov. 8, 1945. [Class 40 (viii)] A high-frequency filter system comprises a pair of Lecher wires spaced less than #/2#, where # is the operating wave-length and having a length equal to an integral number of quarter wave-lengths, a coupling member being disposed between the wires for unequally distributing over a distance less than half of their length the opposed coupling therebetween caused by the electric and magnetic fields. At the spacing and length chosen the capacitative and inductive coupling between the wires would cancel out if it were not for the coupling member. As shown, signals from an aerial 10 pass to a filter using three wires 13, 14 and 15 forming two pairs grounded at their lower ends. Shields 17 and 18 placed in a position where inductive coupling predominates cause a resultant coupling between the wires which then form a band-pass filter between aerial 10 and element 12. In an alternative construction the wires may be connected by condensers in a region where capacitative coupling predominates. The position of the coupling members and the length of the wires may be adjustable.
