Abstract: 435,083. Electrically-operated valves. BRITISH THERMOSTAT CO., Ltd., Windmill Road, Sunbury, Middlesex, and PAYNE, M., 50, Hook Road, Surbiton, Surrey. Dec. 31, 1934, No. 37370. [Class 135] In a thermostatically or pressure controlled valve a, Fig. 2, operated by a reversible electric motor through reduction gearing, the motor has two opposed field windings p, q, Fig. 3, connected respectively to two contacts g, h, of a thermostatic or pressure operated switch mechanism, the motor circuit being closed through one or other of these windings by the engagement of one or other of the contacts with a third contact j and the resulting movement of the valve opening the motor circuit so that the valve stays in its new position until a further change of temperature or pressure occurs. As shown, the windings are connected by flexible leads x, y to two insulated contacts g, h carried on leaf springs z attached to an arm f actuated by a known type of metal bellows device. These contacts embrace a third contact j adjustably mounted on a rod k connected to a screwed part n of the valve spindle b so as to move when the valve moves. The contact j is connected by a flexible lead w to a source of current. The arm f is biassed by an adjustable spring (not shown). The two contacts may be carried by the rod k and the contact j by the arm f. A rocking arm may be employed instead of the rod k. The motor is designed so as to be capable of being left indefinitely in a stalled condition without damage so that disconnection of the motor circuit in the valve end positions is avoided.

Title: Improvements relating to gear change mechanism for motor vehicles
IPC: F16H63/14
Filed: 1938-12-28
Abstract: 523,174. Controlling change-speed gear; ratchet gearing. BIRMINGHAM SMALL ARMS CO., Ltd., and PERKINS, H. Dec. 28, 1938, No. 37578. [Classes 80 (ii) and 80 (iii)] In Specification 486,144 a gear changing mechanism, more particularly for motor cycles, is described in which a-shaft 7, Fig. 2, connected to the gear change mechanism is adapted to be moved step-by-step by repeated movements of a lever 13. This is effected by a pair of pawls 11, Fig. 5, mounted on a carrier plate 10 and adapted to engage a ratchet member 3 fixed on a shaft 1 which also carries a toothed quadrant 4 engaging a pinion 6 on the shaft 7, the quadrant having notches 8 engaged by a spring detent 9. The lever 13 is integral with a sleeve rotatable on the shaft 1, which sleeve carries a pawl actuating plate 14 having a lug 15 adapted to engage the tail of the pawls which are normally held clear of the ratchet teeth by light springs 27. The lever 13 is brought to mid-position by a spring 16 coiled around the sleeve and having its ends crossed to engage a pin 17 fixed to the gear casing, and a pin 20 on the pawl carrier plate. This spring does not satisfactorily ensure tilting of a pawl to cause it to engage the ratchet teeth and, to overcome this objection, according to the invention a spring-controlled detent 23 is employed and arranged to engage a notch or gap 24 in the edge of the carrier plate when in its central position. This detent prevents movement of the carrier plate before the nose of the pawl is brought into engagement with the ratchet teeth, thus obviating the possibility of a gear being slipped, which is liable to occur when the spring 16 has become weakened.

Abstract: 813,004. Radio reflectors. CHAMIER, Sir J. A. Aug. 8, 1957 [Dec. 12, 1956; Jan. 8, 1957], Nos. 37896/56 and 786/57. Class 40 (7). A group of eight corner reflectors such as may be used by small sea-craft are constructed so as to be collapsible. The group is formed of four main plane reflector elements and four subsidiary ones. The four main elements each have a straight parallel edge and all these are held adjacent to each other in such a way that the elements are free to pivot. The subsidiary elements are hinged one to each main element along a line perpendicular to the straight edge already mentioned and means are provided to erect them to a position perpendicular to the main elements. Fig. 1 shows an embodiment in which main elements 11, 12, 13 and 14 are held with their long sides adjacent and parallel by means of sleeves 15 and 16 placed over extensions of the rods forming these sides. The elements are pivotable in the sleeves so that the group may be folded flat. Hinged to each main element along a line perpendicular to the long sides is one of the subsidiary element 18, 19, 20, 21. These fold up flat against their respective main elements for packing but are urged out. wards by springs 26, 27 and so on, when the group is opened. When they lie perpendicular to the main elements they are restrained from further movement by check wires such as 28, 29. To increase the rigidity of the structure tie wires 30 are run between the main elements one, having a hook 30a, being releasable for collapsing the structure. In another embodiment (Fig. 2) the main elements are hinged together at the top and bottom of the assembly and the subsidiary elements 38, 39, 40, 41 are drawn upwards about their hinged sides by means of cords 52, 53, 54 and 55 whose lower ends are secured to rings (such as 46, 47) on these elements and which pass through guide rings such as 48, 49, 50 and 51 before being tied off at ring 57 by which the group is supported. Upward movement of the subsidiary elements beyond the plane perpendicular to the main elements is prevented by stops or by limit wires such as that shown at 59. When the group is erected a collar 56 is pushed down over the hinge 35 and joins the cords 52 to 55.
