Title: Improvements in Disc Brakes
Inventor: KNIGHTS RICHARD NORTHAM
IPC: F16D65/14
Filed: 1966-08-13
Abstract: 1,191,263. Disc brakes. DUNLOP CO. Ltd. 14 Aug., 1967 [13 Aug., 1966], No. 36329/66. Addition to 1,119,207. Heading F2E. In a disc brake of the kind claimed in claim 1 of Specification 1,119,207 having brake assemblies 4, 5 at opposite sides of a disc 2 and operated by a ball-and-ramp expander mechanism, balls 17 are located in a plurality of pairs of ramped recesses 16 in a first and second thrust members 10, 13 and an adjustment mechanism comprises a reaction member 14 keyed against rotation relative to the second thrust member 13, an adjuster 8 mounted in screw threaded engagement with a tie rod 6 connecting the braking assemblies 4, 5, a first coiled clutch spring 22 arranged so that on application of the brake and after the first thrust member 10 has moved through a predetermined angle the first clutch spring 22 will rotate without turning the adjuster 8, whereas on release of the brake the clutch spring 22 rotates the adjuster 8 and a second coiled clutch spring 25 arranged to prevent rotation of the adjuster 8 during application of the brake. Each friction element 4, 5 is axially slidably supported on a pair of pins (not shown) located in spaced-apart positions adjacent the inner periphery of the disc. An end 23 of the clutch spring 22 is arranged within a slot 24 secured to the lever 15 so that when the lever is moved to operate the brake if wear of the brake assemblies 4, 5 has occurred the side of the slot 24 engages the end 23 of the spring 22 and the spring is rotated about the adjuster 8. On relase of the brakes the side of the slot 24 rotates the spring and adjuster to compensate for the wear. To avoid locking of the brakes after wear resulting from light braking in which no adjustment has been made, the clutch spring 22 is arranged to slip in the brake releasing direction at a pre-determined torque. The second clutch spring 25 has an end 27 located in a screw 29, located in the adjuster 8 and prevents the adjuster rotating when the brakes are applied but allows it to rotate on release of the brakes. Alternatively the end (33, Fig. 2, not shown), of the second clutch spring (34) may be located in a slot (32) in a ring (31) positioned within the adjuster 8 by a spring retained pin (36) received within one of four slots 35 in the ring (31). The brake may be returned by retraction springs.

Abstract: 1408727 Making wires; drawing SIEMENS AG 2 Aug 1973 [3 Aug 1972] 36822/73 Headings B3A and B3P [Also in Divisions C7 and H1] A composite wire having an aluminium core I and a niobium sheath 2 is produced by cold drawing an assembly of an aluminium core 1 and niobium sheath 2 covered by a material 3 aiding the drawing operation to form a composite wire, removing the drawing aid material 3 and then smoothing the surface of the composite wire by cold working. A superconductive cable is made by cold drawing in a single or plurality of steps to produce at least an 80% reduction of area an assembly consisting of an aluminium rod 1 and a niobium tube 2 covered by a material 3 facilitating the drawing operation such as a copper tube 3, a layer of varnish or a layer of niobium pentoxide produced by anodic oxidation of the niobium tube 2. The niobium tube 2 may be sealed at its ends before drawing. After removing the drawing aid material 3, the composite wire is swaged by a rotary swaging machine (Figs. 3 and 4, not shown) to round and smooth the wire. The wire may be swaged between the drawing steps. The composite wire produced may be heated at 50-100 C. for 5-30 minutes.

Title: Improvements in or relating to magnetic tape reproducing apparatus
Inventor: RICHARDS CLAUDE LANGDON
IPC: G11B15/60

Abstract: 789,520. Magnetic reproducing apparatus. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Dec. 20, 1955 [Dec. 22, 1954], No. 37037/54. Class 40 (2). A magnetic tape apparatus adapted for use with both a tape of a first kind carrying complementary tracks for simultaneous reproduc. tion and of a second kind carrying independent tracks for consecutive reproduction, comprises a multi-track reproducing head having a sufficient number of sections to reproduce simultaneously the separate signals from the respective tracks of a tape of the first kind, at least one separate single-track reproducing head for the reproduction of signals from at least one of the tracks of a tape of the second kind, and selective means for rendering the different heads effective. The embodiment described shows an apparatus with a tape 3 carrying twin tracks in which a double-track head 6 is employed for reproducing simultaneous signal tracks, such as in a binaural system, and separate single-track heads 7, 8 for reproducing independent signal tracks. The apparatus is preferably provided with a three-position manual control 27 coupled to electromagnetic relays 28 by means of which a switch mechanism 23 appropriately conditions the circuits of the heads 6, 7, 8, amplifiers 24 and loud-speakers 25, 26. Position A of control 27 conditions the apparatus for simultaneous reproduction, while positions B and C condition the apparatus for reproduction of the independent recordings, respectively, for the reproduction of one track or the other. In an alternative arrangement, Fig. 2, the control 27 controls the bringing into operation of pressure members 29, 30, 31, to bring the tape into contact with one or other of the heads 6, 7, 8 respectively.

Abstract: 1,056,539. Variable-ratio gearing. INPOWER WORKS (PROPRIETARY) Ltd. Sept. 20, 1963 [Sept. 28, 1962], No. 37136/63. Heading F2D. Epicyclic gearing has planet gears 16 fast with vaned wheels 18 which pump liquid from a centrifugally formed ring 56 into pockets 42 against the centrifugal head of liquid contained therein to provide the necessary reaction for the transmission of torque through the epicyclic gear. As shown, a planet carrier 12 is fast with an input shaft 10 and carries the planet gears 16 meshing idler planet gears 28 which mesh an output sun 26, a drum 12a containing the liquid being freely rotatable about the input shaft 10 and output shaft 22. The carrier 12 has inwardly directed partitions 40 fixed thereto which co-operate with the drum 12a to form pockets 42. In operation, with the output shaft stationary, rotation of the input shaft rotates the planets 16 and pump wheels 18, gradually causing the drum 12a to be entrained and the formation of the centrifugal ring of liquid 56. In a modification the drum 12a is integral with the planet carrier 12, in another modification the idler planets 28 are dispensed with, the planets 16 meshing directly with the output sun 26. In a further modification, the output sun 26 is replaced by an output ring gear. In another modification (Fig. 6, not shown), the drum is formed as the input member and has internal teeth meshing the planet gears 16 which mesh the output sun 26 through idler planets 28, the planet carrier 12 being freely rotatably mounted about the input shaft 10. In another modification the planets 16 and sun 26 are formed as sprockets which are interconnected by a chain. The vanes of the pump wheel 18 may be straight or curved or they may be formed as buckets.
