Filed: 1971-04-30
Abstract: 1349862 Brake lever mechanism; wire strainers; linkwork H O SCHROTER 30 April 1971 [2 May 1970] 12470/71 Headings F2E F2G and F2K A straining lever mechanism, e.g. for brakes, comprises a pivoted operating lever 1 on which is fulcrummed a control lever 11 having attached thereto an output force transmission member 8. In the released condition of the mechanism the control lever 11 engages a fixed abutment 14 about which the lever 11 swings during the initial operating movement of the operating lever 1. The control lever 11 is so mounted that the swinging movement causes the longitudinal axis of the transmission member to move towards the pivot of the operating lever 1 so that the axis intersects or passes across the fulcrum of the control lever 11. For the remainder of the operating movement the control lever 11 is maintained in a fixed position relative to the longitudinal axis of the transmission member as by the control lever abutting the lower surface of the operating lever. In the construction shown the operating lever 1 constitutes a handbrake lever which may be held in one of a plurality of positions by a spring biased pawl and ratchet mechanism. Two output force transmission members 8 are provided (Fig. 2, not shown) each being connected to a different brake. In a modification the free end of the control lever is interposed between the fixed abutment and a cam face, the cam face urging the control lever over centre into engagement with the abutment on release of the brakes. In a further embodiment (Figs. 4, 4a, not shown) the fixed abutment comprises a pair of cam slots in which ride rollers affixed to the operating lever. The force transmission member works in thrust and the operating lever consists of a brake pedal.

Title: Improvements relating to electric fires
IPC: F24C7/00
Filed: 1930-04-23
Abstract: 348,349. Imitation fires. BANCROFT, F. E., 37, Hart Road, Fallowfield, SMETHURST, H., 1, Glenham Grove, Brook's Bar, BURROWS, G., 6, St. Paul's Road, Withington, all in Manchester, and ASSOCIATED ELECTRICAL INDUSTRIES, Ltd., Bush House, Aldwych, London. April 23, 1930, No. 12555. [Class 126.] A flicker device for imitation fires comprises one or more mirrors 22, 23, flexibly supported, for example by helical springs 20, 21, from an arm 16 which is vibrated by an electromagnet 26 intermittently energized by the movement of the plunger or armature, which makes and breaks the electric circuit. The moving mirrors reflect the light from a lamp 10 through or on to the imitation fuel. In the construction shown, the rod 16 is vibrated by the plunger 17 of the solenoid 26, the plunger being secured to one end of a rigid strip 15 which is attached at its upper end to a spring strip 14 and intermediately to the rod 16. An insulating disc 19 on the plunger engages the upper end of a spring 31 and causes it to make contact with a contact member 32 when the plunger moves inwardly, thus short-circuiting the solenoid and allowing the plunger to move outwardly. The lamp 10 is preferably wired in series with the solenoid, and may be caused to flicker by using either a solenoid of high resistance or an extra resistance in series with it. Another construction is described in which the axis of the solenoid is vertical, and a vertical extension of the plunger is attached to the centre of the horizontal rod carrying the springs to which the mirrors are attached, which is thus reciprocated vertically. Between the rear edge of the translucent plate 4 carrying the " fuel " and the back of the casing is a strip of translucent material coloured in irregular streaks of red, yellow, and black.

[Classes 40 (iii) and 40 (v)] An amplifier or cathoderay tube having a reactive impedance Z4 in series with the cathode has the response rendered independent of frequency by applying the input voltage to a potentiometer which includes at least one element of the form kZ4 where k is independent of frequency. The invention is contrasted with that of Specifications 459,251, 478,815, and 506,946, in which the same object is achieved by choosing the anode impedance and is particularly applicable to discharge devices such as cathode-ray tubes which have a control electrode but do not include an impedance in the output circuit across which an output voltage is derived. The Specification gives a mathematical analysis and formulae that when satisfied give the required independence of frequency. The input voltage to the potentiometer network Z1, Z2, Z3 may be the output voltage of a network or amplifier according to Specification 459,251, 478,815, or 506,946, and the impedance of the potentiometer network is large compared with the output impedance of the network or amplifier.

Title: Improvements in and relating to Springs, particularly for Snap Fasteners.
IPC: B21F45/18
Filed: 1919-05-20
Abstract: 128,548. Baird Machine Co., (Assignees of Lewis, A. J.). June 17, 1918, [Convention date]. Springs; fastenings.-Snap-fastener and like springs are formed by bending a length of wire around a recessed former by means of a pair of recessed jaw-like members, and then pushing the ends of the wire so as to cause the arms of the blank to fold into the recess in the former by means of a punch formed with recesses which receive the ends of the wire. The spring so formed may be transferred automatically into the article which is to receive it, e.g. into a socket which is to receive the shank of a snap fastener member. A length of wire is fed through a guide 52, Fig. 1, out off by a cutter 53, and the cut length is bent around a hollow former 54, which can move in a guideway 40 in the machine bed 20, by means of a pair of jaws 23, mounted on spring-controlled lever arms 24 carried by a slide 21 reciprocated by a cam 31 acting on a roller 30. The jaws 23 bend the blank 44, Fig. 4, around the former, and cause its ends to be received in recesses 43 arranged at either side of a forming punch 26 carried by a cam-operated slide 22 which moves in guideways on the slide 21. The punch 26 then advances and its forward end is received by a recess 55 in the hollow former 54 and a double bend is formed in the spring as indicated in Fig. 6. After this, the jaws 23 may be operated by raised parts 64 on the side cams 37 which effect the normal operation of the jaws, and this movement of the jaws 26 sets the fastening in the form indicated in Fig. 7. The spring thus formed is carried by the jaws 23 to a position from which it can be inserted into a socket fastener member 47 by means of a reciprocating assembling punch 50 which pushes the finished spring into the member 47 carried by a reciprocating slide. Alternatively an intermittently operated rotary member may be arranged to receive the member 47. In either case, a pressurereceiving member 48 may be arranged in the bed 20 so as to take the pressure of the securing operation. The forward end of the punch 50 is shaped as shown in Fig. 13, with a central aperture surrounded by an annular rib 59 with two radial projections 60, 61 which push the spring into the socket member 47.
