Title: Improvements in shock sensitive latch-releasing devices
IPC: E05B65/12
Filed: 1962-04-17
Abstract: 998,484. Locking rotary elements. ARROW ELECTRIC SWITCHES Ltd. April 17, 1962 [April 19, 1961], No. 14761/62. Heading F2E. [Also in Division H2] A device responsive to predetermined shock values for moving a holding member from a predetermined position, e.g. from a locking position to a releasing position, comprises shock responsive means which are connected by a flexible element to the holding member, the arrangement being such that the holding member is moved from the predetermined position in response to a predetermined shock force value irrespective of the force direction. As shown, the spindle 29 of a rotary electric switch carries a latched member 28 which is normally prevented from rotating in one direction by a lug 26 which is vertically slidable in a housing formed by a pair of similar recessed members 10 and is urged towards the member 28 by a spring 21. A cable 14 passes through a central space between the members 10 being trained around a pulley 30 on the lug 26 and fixed pulleys 32, 34. The ends of the cable are secured by set screws 62 in masses 16, 18 arranged externally of the housing and abutting identical masses 36, 38 which are loose on the cable and accommodated in recesses within the housing. As a result, equal shocks delivered in any direction increase the tension in the cable by the same amount so that any shock exceeding a predetermined force value results in the lug 26 being withdrawn from the member 28 against the action of spring 21. The latter is adjustable by screw-and-nut means 22 to vary the responsiveness of the device. The lug 26 may be manually released, either by plungers 66 mounted on the device and interconnected by a manually-operated bar, or by the energization from a remote control point of solenoids 40, 50 which extend stepped armatures 42, 52 towards the masses 16, 18 against the action of springs 46, 56. The masses 16, 18 are engaged by the plungers or armatures, respectively, and moved to one of other of the dotted-line positions to pull the cable 14, so withdrawing the lug 26. Specification 587,059 is referred to.

May 25,1932, No. 14894. Convention date, June 25, 1931. [Classes 40 (iii) and 40 (v).] Specification 315,836, [Class 40 (v), Wireless signalling &c.], relates to an amplifier having a compensating - valve for shaping the characteristic of a main valve. The present Specification describes an amplifier of this kind for use in double-current telegraphy in which the compensator valve 19 conditions the potential drop in a resistance 21 in the plate circuit of the main valves 17, so that while for negative impulses the part ab, Fig. 2, of the characteristic is unaffected, the part bc which deals with positive impulses is transformed to the shape be. The incoming signals are applied through valves and a shaping network to terminals 1, 1 of an input potentiometer 18 which feeds the grids of both the compensator valve 19 and the main valves 17. The outgoing signals are taken at terminals 20 from a resistance 22 and battery 32 which lie in the plate circuit of the main valves 17 but not in that of the compensating-valve 19. The valve 19 is so biassed that it is unaffected by negative signals and has no influence on the part ab of the characteristic of the main valves 17 ; but on receipt of positive signals it produces a potential drop in the resistance 21 and so transforms the part bc of the characteristic to the shape be.

Abstract: 1,185,517. Coating by extrusion. POLYMER CORP. 4 April, 1967 [4 April, 1966]. No. 15295/67. Heading B5A. [Also in Division F2] In a method of coating a primed substratel e.g. a galvanized wire or a pipe having a vinyl primer, by extrusion, the coated substrate, at least at the interface between the coating and primer, is heated to a temperature in excess of the temperature at which the coating material is extruded on to the substrate. The heating may be effected by preheating the substrate, but it is preferred to use dielectric, induction, resistance or ultrasonic heating techniques. In the embodiment shown, a primed metal pipe 60 receives a coating 90 of PVC delivered from a crosshead die 10 equipped with vacuum lines 64 and supplied by a heated impeller system 24. Preferably pipe 60 is moved through die 10 at a somewhat higher speed than the speed of extrusion to pull the coating on to the pipe, the presence of a vacuum in pocket 56 assisting this operation as well as preventing air being trapped between the coating and the pipe. The coated pipe is heated by induction heater 82, e.g. to a temperature in the range 200-400 C., the coating is subjected to pressure by transversely reciprocable shoes 100, (102) and 110, 112, see also Fig. 2 (not reproduced), and the product is finally cooled in a spray bath 120. In modifications the heating and cooling devices are combined, Fig. 3 (not shown), and pressure may be applied to the coating by the use of inflated bags, staggered rollers, pressure rings or directly by a fluid or gas. Specific other coating materials mentioned are polyamides, cellulosics, polyacetals, polyolefins and, as an example of a thermosetting resin, epoxy resin.
