Title: Improvements in disc brakes
Inventor: HAMBLING STEWART KEVERN
IPC: F16D55/2255
Filed: 1962-05-03
Abstract: 1,020,452. Disc brakes. GIRLING Ltd. April 25, 1963 [May 3, 1963 (3); May 13, 1962], Nos. 12674/62, 12675/62, 12676/62 and 14322/62. Heading F2E. In a disc brake of the kind in which a directly actuated friction pad 22 is adapted to be brought into engagement with one face of a rotatable disc 10 by actuating means 23 located in one limb of a caliper or housing which straddles a portion of the periphery of the disc, a friction pad 25 located in or on the other limb of the caliper being brought into engagement with the opposite face of the disc by the reaction on the caliper, the directly actuated friction pad 22 is guided in a straight line for movement towards and away from the disc in a direction which is inclined with respect to a line at right angles to the surface of the disc in a direction such that the directly actuated pad is guided towards the disc in the same direction as the normal direction of disc rotation, such that when the friction pad is applied to the disc the frictional engagement between the pad and the surface of the disc produces a servo or selfenergizing action which increases the retarding effect of the brake. In the disc brake illustrated in Fig. 2 the piston 23 is adapted to be moved by fluid under pressure supplied to the outer end of the cylinder 24 and, through a wedgeshaped block 21, the friction pad 22 is moved into frictional engagement with the adjacent face of the brake disc 10 and the caliper, formed by a bridge piece 11 (Fig. 1, not shown), and two spaced parallel bolts 14, 15 inclined at an angle of 45 degrees to the plane of the disc, draws the friction pad 25 into engagement with the opposite face of the disc. The force exerted by the piston on the friction pad 22 has a component in the direction of movement of the surface of the disc with which the pad engages, the disc being rotated in the direction indicated by the arrow, and the tendency of the pad to be carried round the disc urges the block or carrier 21 to enter into engagement with the inclined abutment surface 18 which exerts a force on the pad urging it towards the disc so that the brake has a powerful self-energizing action. Alternative embodiments are disclosed in the Specification including a caliper which is adapted to pivot instead of sliding relative to the disc (Figs. 3 and 4, not shown), an arrangement similar to that disclosed in Fig. 2 but having a roller member between the wedgeshaped block 21 and the abutment surface 18 (Figs. 5 and 6, not shown), different forms of the brake in which the actuated friction pad is applied to the disc by pistons working in fluid pressure cylinders of which the axes are at right angles to the face of the disc but the directly actuated friction pad 22 is adapted to be guided at an angle 45 degrees to the plane of the disc (Figs. 7-9 inclusive, not shown), and a split caliper arrangement (Figs. 10 and 11, not shown).

For facing or counterboring the end of a shaft the tool slide assembly 32 is mounted, as shown, Fig. 6, on an end plate 17 of the body member. 10 but for turning a cylindrical surface the assembly 32 is adjustably mounted by T- headed bolts 35 on a platform 20 extending longitudinally of the body member. A V-belt drive to matching grooves 24, 30 in the end caps 11, 12 and body member rotates the lathe around the shaft and an abutment member is located so that, once in each revolution it contacts a capstan 43 on the tool slide assembly which through gears 42 and feed screw 41 feeds the tool mounting 38 incrementally. A tumbler, not shown, reverses the direction of feed at the end of each traverse. Collars, not shown, located on the shaft externally to or internally of the end plates 17, (16) prevent endwise displacement of the lathe. Where the shaft axis is not true or its surface is irregular separate half bearings may be mounted thereon first and adjusted to the desired axis and the lathe then set up: on these bearings. The lathe may be driven by a shaft (Fig. 10, not shown). For lapping a shaft a spring-tensioned bracelet 48 of hingedly interconnected lapping stones is connected to the tool mounting 38 in place of the tool 39 the lapping stones thereby being rotated and traversed along the shaft and pressed thereagainst under constant and equal pressure.

Abstract: 1,243,764. Coaxial printed circuits. BUNKER RAMO CORP. 18 March, 1970 [29 April, 1969], No. 12946/70. Headings H1A and H1R. A coaxial circuit of the microminiaturized type is built up from a conductive base by laminating there-on, in a series of steps, precisely dimensioned alternate layers of copper foil and epoxy resin. Selective etching is used at appropriate stages to form the centre conductors and to remove unwanted dielectric portions. Electroforming techniques are then used to complete the conductive encirclement of the centre conductors and to provide a top layer of the required thickness. Provision for making interconnections to the central conductors is accomplished by drilling holes in appropriately located dielectric filled slots chemically milled in the outer plates, each hole having a conductive layer formed there-in to provide electrical connections to a respective central conductor intercepted thereby. Ferric chloride may be used as an etchant for the copper layers, and a chromate-sulphide type of solution used for etching the epoxy resin dielectric layer.
