Title: A mechanical ball-kick or ball replay mechanism for game apparatus
IPC: A63F7/24
Filed: 1935-10-08
Abstract: 461,658. Table games. FRANCIS, A. W. J., and HERBERT, J. M. Oct. 8, 1935, No. 27788. [Class 132 (ii)] [Also in Group XVIII] A mechanical ball-kick or ball-replay mechanism for game apparatus of the kind in which balls are propelled over a playing surface provided with pins and/or apertures denoting scoring positions comprises a ball-kick member 10, Fig. 2, pivoted at 11 and controlled by a spring 16, the member 10 being held in its set position, as shown, by a pivoted catch 18 which is held in engagement with the end of the member 10 by the tension of the spring 16. The upper end of the lever 10 projects through a slot 14 in the playing surface 13 and may be surrounded by a guideway 15. If a ball that has been projected over the surface 13 in the normal course of playing a game, enters the guideway 15, its momentum moves the lever 10 slightly thereby allowing the catch 18 to fall by gravity. The spring 16 now moves the lever 10 sharply forward to re-project the ball over the surface. Instead of the catch being released by the ball hitting the lever 10, it may be released by the ball itself or another ball hitting and depressing a projection 20 which passes through a slot 21 in the surface 13 and is connected by a link 22 to a pivoted arm 23 bearing a cam 25 for releasing the catch. The ball-kick is cocked or reset by a lever 30 connected by linkage 29, 27 to a push-button 26, which operates the usual ball raising device. When the button is pushed in, the lever 30 is rocked on its pivot 31 to move the upper end of the lever 10 in the direction of the arrow, at the same time a flexible spring on the lever 30 raising the catch 18 into its operative position. In a modification, Fig. 4, the catch 18, which has a hook 42 engaging a pin 43 on the lever 10, is released by another ball dropping through an aperture 41 to tilt a lever 46 connected by a link 45 to the catch or to a releasing arm 23 provided with a cam 25. In a further modification, Fig. 5, the ball-kick member is a plunger 50 slidable in a guideway 51 and controlled by a compression spring 52, the catch 18 and resetting lever 30 engaging respectively a shoulder 53 and rear flange 54 on the plunger. The flange 54 limits the forward movements of the plunger. The resetting mechanism in all cases may be actuated by the usual coin inserting slide or by an independent control. Specification 443,181 is referred to.

Filed: 1935-10-12
Abstract: 460,316. Aircraft alighting - gear. DOWTY, G. H. Oct. 12, 1935, Nos. 28234 and 31582. [Class 4] A retractable under-carriage for aircraft includes auxiliary additional means for emergency extension comprising a source of energy and transmission means between said source and the point to which extending power is applied. In one form, a radius-rod having articulated parts is pivoted in the aircraft and to a shock-absorber unit which carries the landing wheels. A cord is led from the pivotal connection with the unit over a pulley situated on the axis of articulation of the parts over a pulley 10 and is furnished with an abutment 12 in a cylinder 11. Upward movement, under the control of the pilot, of a member 19 permits balls 18 to pass into a recess 22 and release a previously compressed spring 16 to tension the cable and effect emergency extension of the alighting gear. A spring 14 maintains cable 8 taught. A small cartridge or bottle of compressed air or gas may replace the spring. In a modification, in which an undercarriage is extended and retracted by a hydraulic jack comprising a stem 33 fixed in the aircraft and guiding an annular jack-piston, the stem is made hollow, is provided with a non-return valve 40, and a connection 38 for a pressure gauge. Fluid under pressure is stored in the stem. On failure of the usual extending gear, the pilot rotates a pulley 36K which through a quick-pitched thread 36H moves a valve 36D to close the access 36A to the normal source of energy and open a port 36G to permit the fluid under pressure in the stem 33 to be admitted under the piston and effect extension of the alighting gear. The emergency source of energy may be liquid separated by a plunger from a reservoir of compressed air. The emergency gear may actuate or release locks and operate indicating means.

Title: Deceleration and stop-light signalling means for motor cars  and other vehicles
IPC: H01H35/14
Filed: 1973-06-18
Abstract: 1436227 Road vehicle signalling E A BRYANT 18 June 1973 28851/73 Heading G4Q [Also in Division H1] In a motor vehicle system affording a warning light when a throttle switch or a brake switch are actuated and wherein the throttle switch is an inertia switch actuated briefly on sudden throttle release, electrical time delay means sustains the light initiated by the actuation of the inertia switch. General circuit arrangement, Fig. 11.-Stop lamps 123 are energized via brake switch 122 and a circuit bridging the latter; such circuit includes a microswitch 26, inertia switch 12, relays 57, 59 and associated contacts, and a thermal switch 99 incorporating an extensible wire 111. When switch 12 closes a temporary earth is connected to the relay coils and closure of contacts 69 causes the stop lamps to shine and to continue to do so when switch 12 breaks; also contacts 71 close to energize wire 111 and, after a delay, closure of contacts 103, 104 thereby breaking contacts 69, 71. If, as usual, brake switch 122 closes before contacts 103, 104 close, device 50 is de-energized. Switch 26 only opens when the throttle approaches full opening and then renders inertia switch operation ineffective; thus spurious operation by actuation of the inertia switch when a throttle opening is stopped suddenly at the fully open position is prevented. Switch 26 may, however, be omitted. A dash-board lamp 127 glows when current flows through wire 111. SWITCH DETAILS Inertia switch. Fig. 3.-The switch is clamped by collets to throttle linkage rod 23 and the inertia switch swings bodily about the rod's axis and the rod rotates, Figs. 1, 2 (neither shown). An adjustable striker (27) (Fig. 2) clamped to casing 13 actuates switch 26 when the throttle is fully open. An insulating plate 31 carries an outer connector leaf 32 connected to a contact arm 33 by a rivet 34. Head 36 is adjustable by screw 37 and when the throttle suddenly closes a weighted resilient leaf 41 moves to cause a contact 42 to close on fixed contact 36, Fig. 5 (not shown). Time delay means, Figs. 6 and 11, incorporates coils 53, 54 and an expansion wire III (see also Fig. 7, not shown). Once the inertia switch closes the circuit is held and after a time interval determined by wire 111 and a coil 114, contact 104 engages contact 103 thereby causing sets of contacts 69, 71 to open and the circuit reverts to its original condition.

IPC: C25D5/54
Filed: 1959-08-26
Abstract: 927,205. Couplings; electrolytically plating reduced oxide surfaces. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Nov. 10, 1960 [Aug. 26, 1959], No. 29175/59. Classes 38 (1) and 41. In an oxide-film resistor parts of the surface of the film are chemically reduced and then electroplated to provide metallically reinforced track portions for the wiper contact in the case of a variable resistor or terminations in the case of a fixed resistor. The preferred deposition metal is rhodium, though other metals such as gold or copper may be used. The metallic oxide film may be deposited upon a glass base by spraying a mixture of tin and antimony chlorides in aqueous solution on to the base which is held at a temperature of 500-600 C. The oxide film may then be masked with a cellulose paint over those portions not to be plated, and the surface of the exposed oxide portions mildly reduced using a paste of zinc powder in dilute HCl solution. The reduced surface is then cleaned and electroplated, e.g. by applying the plating solution, sulphuric or phosphoric acid in the case of rhodium, with an impregnated cotton wool tampon surrounding a carbon rod which is made the anode, while the oxide film constitutes the cathode. The metal deposit is lightly abraded and the paint mask removed using a chalk suspension in water, and then the deposit is annealed in oxygen-free nitrogen, argon or a vacuum at 500 C. for about five minutes. A thin film of a silver paint may be applied to metal terminations before soldered connections are applied. U.S.A. Specification 2,762,725 is referred to.
