Abstract: 521,827. Asymmetrically-conducting resistances ; electrolytic reduction of copper oxide- WESTINGHOUSE BRAKE & SIGNAL CO., Ltd. Nov. 29, 1938, No. 34788. Convention date, Aug. 17. [Classes 37 and 41] The outer surface of the copper oxide layer of a rectifier is reduced electrolytically to form a copper contact surface in a bath comprising , ammonium hydroxide preferably in weak aqueous solution, e.g. 0.2 per cent. by volume of concentrated NH4OH (s.g. 0.880). Current of density of 12 amps. per sq. ft. is passed for 3-5 minutes, the bath being at room temperature and mechanically agitated. 0.05 per cent by volume of a saturated solution of ammoniun sulphate may be added tc the solution whereby the voltage required is reduced. In preparing the oxide surface annular, copper blanks are mounted in pairs on a support and heated in an oxidizing atmosphere, whereby they are coated with an inner layer of cuprous oxide and an outer layer of cupric oxide, the layers being thinner on the facing surfaces. They are then quenched and'treated with an aqueous solution of 2 per cent. by volume of sulphuric acid and 0.1 per cent. by volume of hydrochloric acid whereby both layers are removed on the thinly coated side and the cupric oxide layer only on the other side. In the electrolytic treatment two blanks A are mounted with their oxide coatings outwards on either side of a metal washer 3 to which are cemented rubber washers 4 extending beyond the periphery of the blanks A. Rubber washers 6 masking the outer edge of the oxide coatings are then applied and the assembly clamped between washers 7. Nickel or other metal may be plated on to the reduced surface. A suitable nickel bath contains NiSO4.7H2O 27 oz., NiCl2.6H2O 4 oz., boric acid 6 oz. per U.S.A. gallon.

Title: Adjuster control means for internal shoe-drum brakes
Inventor: HILL ALBERT CHARLES
IPC: F16D65/56
Filed: 1964-08-25
Abstract: 1,059,225. Internal shoe-drum brakes. GIRLING Ltd. Aug. 10, 1965 [Nov. 7, 1964; Aug. 25, 1964], Nos. 34837/64 and 45455/64. Heading F2E. In an automatic adjusting device for internal shoe-drum brakes, in which the adjuster is actuated by angular movement of an adjusting lever 23 associated with a shoe 11 through an angle limited by a stop of which the position is defined by a radially movable button or plunger 36 extending through the flange and a friction lining 12 of the shoe into engagement with the braking surface of the drum, the angular move ment of the lever 23 on application of the brake being insufficient to effect adjustment of an adjustable strut 14 until a certain amount of wear of the shoe lining has taken place and the position of the stop has been changed by inward movement of the plunger. Inward movement of the plunger causes pivotal movement of a bell-crank lever pivoted on a pin 33 on the shoe web to increase the clearance between the arm 32 of the bell-crank lever and the end 32a of the lever 23. If the clearance is then sufficient, the pawl 22 formed at one end of the lever 23, on application of the brake, will ride over one or more teeth on a ratchet wheel 15 of the adjusting strut 14 and on release of the brake a return spring 31 moves the lever back and the pawl rotates the ratchet wheel 15 to increase the effective length of the strut or thrust member 14 to take account of brake lining wear. The normal clearance between the end 32a lever and the arm 32 is restored by a resetting lever 38 which is connected by a cable 41 to the shoe 10, the increase in the separation of the shoe ends moving the pivot of the bell-crank lever along a slot in the web of the shoe 11. In an alternative embodiment disclosed in the Specification (Fig. 5, not shown) the radially-movable button or plunger extends through a one-way friction device formed by a spring ring and a coned sleeve to prevent outward movement of the button in the housing and a wedge-shaped member extends through a transverse slot in the button and through guiding slots in the housing to cause actuation of a cable to effect movement of a pivoted lever which bears a pawl to effect adjustment of the strut connecting the two shoes. As shown in Fig. 1, the brake may be applied either by a double-ended hydraulic cylinder 13 or alternatively by cam means 16 angularly movable about a pin which is mounted on the stationary back plate of the brake, the cam being actuated from the hand brake lever by a cable 19.

A pneumatic tyre is filled with liquid by means of a rigid tubular needle 5, having a conical head 15, which is insertable into the tyre chamber 4 through a slit 11 in a rubber valve 6 which is mounted in an aperture in the tyre wall 7, the needle 5 comprising two separate passageways 17, 26 which communicate respectively with orifices 22 and 27, respectively in, and adjacent to, the needle head 15, the passageway 26 being connectable to a liquid supply for filling the tyre, and the passageway 17 being open to atmosphere to vent the air from the tyre during the liquid filling. As shown, the needle 5 comprises concentric tubes 13, 17 which define between them an annular passageway 26, the outer tube 13 projecting at right agles from a base member 12 which has an outlet 19 provided with an inflation valve core 21 and sealed in communication with the inner tube 17. The base member 12 carries also a water hose connection 25 which communicates through the member 12 with the annular passageway 26. The needle head 15 forms a radial flange 16 at its junction with the tube 13 to provide an abutment for one end of a plastic sleeve 28 which is slidable on the tube 13 to cover or uncover the liquid outlet orifices 27. The other end of the sleeve 28 has a flange 29 which, on insertion of the needle through the valve slit 11, abuts the valve flange 8 to be held thereby against further movement through the valve. In use the needle 5, which may be bent, is inserted into the tyre so that its head 19 is disposed to sweep the uppermost part of the chamber adjacent the tyre crown. On withdrawal of the needle, it slides within the sleeve 28 until the apertures 27 are sealed thereby and the head flange 16 abuts the sleeve end whereupon the sleeve 28 and needle 5 are withdrawn as one. The needle 5 may be used for evacuation of liquid from a tyre by disposing it in the lowermost part of the tyre chamber and supplying pressure air through the valve 21 and tube 17. Alternatively, topping up, or gravity emptying may be effected by a needle having a single axial passage, and communicating transverse hole adjacent the needle head.

Abstract: 779,894. Knitting. ZAPADOMORAVSKE STROJIRNY, NARODNI PODNIK. Dec. 23,1953, No. 35758/53. Class 74 (2). For normal yarn changes, yarn guides are moved between low active and high inactive positions (and a yarn cutter actuated) by a cam drum 95 acting through push rods 89-93; but, for crossstriping, certain of the guides, e.g. 18, 19, may be exchanged (and the cutter operated as necessary) by a striping cylinder 47, bearing cams which act through levers such as 74, which cylinder is racked round under the control of jacks 27 borne on the upper part of an auxiliary pattern during which by jacks 15 in its lower part, also effects needle selection. The drum 7 is driven by cams, one to four in number, on a wheel 33 driven at a quarter main shaft speed. The cams act through linkages 38, 40, 41, 42, the pawl 43 and a ratchet wheel 22 having one low tooth 23 among the normal teeth 21. A shield 44 has parts of two different radii and is movable to shield all the teeth, to stop the rotation of the cylinder 7, or to shield only the low tooth, and thus to bring the cylinder to its starting position. The striping cylinder 47 is racked round by a cam disc 13 rotating at needle cylinder speed and acting through linkages 110, 114, 116, 120, pawl 104 and ratchet wheel 49. This racking mechanism may be disabled manually by an arrangement which moves roller 108 away from the disc 13. The ratchet wheel 49 possesses a low tooth. A main pawl shield 133 can prevent engagement of pawl 104 with any of the teeth of wheel 49 and an auxiliary shield' 134 can prevent engagement with the low tooth. The shield 133 is rendered inoperative to cause racking of wheel 49 by the jacks 27 acting through lever 124 and rod 131. The two shields 133, 134 may be controlled together to cover only the low tooth, and so to cause return of the cylinder 47 to its starting position, by cam segments 135 on drum 95 acting through a lever 136, rod 139, lever 142, spindle 143 and lever 144 which can simultaneously control the rod 131 connected to shield 133 and a rod 145 connected to the shield 134. The cylinder 47 is secured in any required position by a brake 55.
