Title: Improvements in locks and bolts for securing van and other doors
IPC: E05C9/04
Filed: 1921-04-26
Abstract: 183,573. Smith, C. H., and Siddens, F. R. April 26, 1921. Double-bolt fastenings.- In double-bolt fastenings, a spring-controlled crosspiece axially slidable with the square operating-spindle has pins or projections taking into recesses in the securing-plate to prevent disengagement of the bolts by vibration. In the form shown in Figs. 1 and 2, the pair of bolts C are connected by the link B<1> operated by the square spindle S on which slides the spring-pressed cross-piece B having pins or projections A entering holes in the securing-plate E. When the pins A are so engaged, the spindle S cannot be turned to operate the link B<1> to release the bolts. To effect this release, a square key is inserted in the square socket G of the spindle S, or vice versa, and the spindle pushed axially against the spring F, carrying with it the cross-piece B until the pins A are free. The key is then turned, turning the spindle S, which turns the link B' and disengages the bolts C. On turning the key until the pins A are opposite their holes in the plate E, the bolts C are re-shot and the spring F causes the pins A to shoot into their holes. In the form shown in Fig. 4, enlarged parts A of the cross-piece B enter cut-away parts D of a boss Z on the plate E, to prevent release of the bolts by vibration.

Abstract: 658,220. Platform lifts. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. May 9, 1949, No. 12327. Convention date, May 22, 1948. [Class 78 (iii)] [Also in Group XXXIV] In a lift system of the kind in which the car is guided by rollers thereon which engage fixed guides in the lift shaft, noise is reduced by inserting sound insulating material between the rollers and the car. Rollers 19, 55, 63 which engage one fixed guide 3 are constructed with resilient rims 21, as described in Specification 643,127, [Group XXXIV], and are each supported on the base 31 through elastomer bushes. Rollers 19, 55 are rotatably mounted on spindles 51 eccentrically secured to members 29, which are each supported by a pair of cups 35, 41 integral with the base, and containing elastomer insulating bushes 33, 39 which are adjustably compressed to give optimum sond damping by collars 43, 45 and nuts 49. Slackening of these nuts also allows members 29 to be rotated to adjust the position of the rollers' axes. Roller 63 is rotatably mounted on a spindle 65 secured to one end of a cranked arm 67, the elbow of which is supported on an elastomer spring 91 which urges the roller into contact with the guide 3. The other end of this arm is connected with a member 71 which is resiliently connected to the base 31 by elastomer bushes 79, 81 in cups 83, 85, the member 71 having a nut 89 on each end for pre-stressing the bushes and for axially adjusting the roller 63. In a modification (not shown) the cranked arm 67 is dispensed with and the member 71 is directly mounted on the base similarly to the members 29. In the event of one or more rollers becoming inoperative a slot 31c in the base serves as an emergency guide shoe.

Abstract: 1533343 Reducing shrinkage BASF AG 29 March 1976 12492/76 Addition to 1470243 Headings D1B and DIP Textile goods consisting of or containing animal protein fibres, e.g. wool and silk are rendered shrink-resistant, non-felting and of improved handle by treatment with an oxidizing agent prior to impregnation with a bath containing an aziridine group-containing compound according to the parent specification. The oxidizing agent is preferably a chlorinating agent, e.g. the potassium or sodium salt of dichloroisocyanuric acid but may be a permanganate, peroxy sulphate or peroxide. The oxidizing agent may be applied batchwise, e.g. in a top-dyeing apparatus or by continuous padding from a liquor at a pH of from 3 to 6 to which an organic or inorganic acid has been added. The oxidation may be followed by dechlorination, using dithionite or peroxide. The ozidized and dechlorinated material may be rinsed and optionally dried or kept in a J-box prior to impregnation with the aziridine group-containing compound. Dyeing, e.g. with an after-chroming or 1:2 metal complex dye, may be carried out between dechlorination and impregnation with the aziridine compound, or after such impregnation. Nitrogen-free wetting agents may be used to assist oxidation and impregnation. Flock, tops, yarn, knitted fabric or woven fabric may be treated.

Abstract: 540,926. Valves. BLAKEBOROUGH, R. A., and BROTHERTON, C. Aug. 3, 1940, No. 12545. [Class 135] A relief valve device particularly adapted for use on pumping mains, supplied by a centrifugal pump, to suppress surge in the mains is adapted to open an outlet to a region of low pressure when the pressure in the mains falls and to close slowly when the pressure is re-established.
