IPC: G07F17/34
Filed: 1931-08-10
Abstract: 391,169. Coin-freed amusement apparatus. SMITH, G., 34, Clieveden Road, Thorpe Bay, Essex, and LENNARDS, W., 175, Railway Approach, Shepherd's Bush, London. Aug. 10, 1931, No. 22557. Divided on 390,180. [Class 27.] ' Relates to coin-freed apparatus of the kind in which a plurality of wheels bearing numbers or representations of " fruit on their peripheries are set in rotation and, if they stop in certain predetermined positions, prizes are automatically delivered, manually operable jointed control levers for controlling the stopping positions being provided. According to the invention, there is provided means for preventing the rotation of the wheels unless the manual controls are used and means for deflecting into a container, as rent for the use of the apparatus, a fixed proportion of the coin inserted. The invention is described in connection with known apparatus in which each reel a, b, c, Fig. 3, has a perforated ratchet disc h for determining the prize-delivery and a star-wheel 83 which is engaged by a jointed stopping lever 80 acting either automatically under the control of clockwork mechanism or earlier by the use of skill control devices 71, Fig. 4. When the skill-controls are used, the upper jointed portions of the levers 80 are allowed to move under the action of springs into engagement with the star-wheels 83. The wheels are spun by a pawl i engaging the ratchet discs h when a rocker arm j on a shaft 68 is returned by a spring k which is energized by operating a hand-lever after the insertion of a coin. According to the invention, the members j, i are held in " cocked " position by a " trigger " 66 which is engaged by an arm 67 on the shaft 68. When the manual control device 71 for stopping the first reel a is operated, it depresses a lever 69 to release the trigger 66 and allow the spring k to act n the rocker arm j and set the reels spinning. Diverting coins periodically.-Each coin 49, Fig. 13, inserted is forced down a shoot p from the position in which it obstructs a pin s on a locking-lever t, which releases the apparatus in known manner, by a depressing arm z connected by a link w to a hand-operated lever. The coin is held in this obstructing position by a pin g on a spring-controlled arm r. The arm z engages a pin 51, Fig. 14, on one arm 52 of a bell-crank lever 52, 53, the arm 53 of which has a pawl 54 for driving a ratchet wheel 55. The ratchet wheel, as described in Specification 390,180, controls mechanism for diverting a fixed proportion of the inserted coins to a rent box. Testing coins; clearing-mechanism; returning coins.-The coins inserted through a slot in the casing are tested as described in Specification 390,180.

Filed: 1946-07-29
Abstract: 615,278. Shaft couplings; securing articles on shafts. GREENE, B., BARNETT, W., and BARNETT, C. July 29, 1946, No. 22560. [Class 80 (ii)] Means for securing a pulley or the like on a shaft comprises a split sleeve 1 loosely mounted on the shaft 2 haying an externally tapered surface 3. The boss 6 of the pulley has an internal conical bore, and a thick radial flange 7 integral with the boss has transverse diametrically opposed tapered channels 8 formed therein which partially register with similar channels 4 in the sleeve 1. Insertion of tapered keys 4a causes a wedging engagement tending to bring the slots into register and cause relative axial movement of the boss 6 and contraction of the sleeve 1 on the shaft 2. This arrangement may be used for coupling shafts of the same diameter together. For coupling shafts of different diameter, each shaft is provided with a split conical sleeve 1 which is in wedging engagement with a common surrounding member 6. Specification 605,703 is referred to.

Title: Safety devices for electric automatic control systems
Inventor: MILSOM FREDERICK ROGER
IPC: G05D1/00
Filed: 1949-08-31
Abstract: 673,379. Automatic servo control systems. SMITH & SONS (ENGLAND), Ltd., S., and FURZEHILL LABORATORIES, Ltd. Nov. 28, 1950 [Aug. 31, 1949], No. 22598/49. Class 38 (iv). In a servo control system for an automatic pilot a testing signal having a signal frequency higher than that to which the servomotor can respond (e.g. 40 c.p.s.) is injected in series with the deviation signal, and its magnitude and phase are checked at the motor terminals to detect any fault in the servo amplifier. As applied to an automatic pilot such as that described in Specification 611,037, wherein the rudder 9 is controlled by signals from a compass 2, rate of turn gyro 1, and speed of rudder displacement generator 5, a testing signal from a modulator 21 is also injected into the amplifier 3. The modulator is fed from a 400-cycle source 25 (common to the other units of the servo system) and modulated at the test frequency by an oscillator 20. The signal at the servomotor terminals is demodulated and filtered to remove any control signals, and then compared with the original test frequency in a demodulator 24 to produce a D.C. output dependent on its amplitude and phase. This output is fed to a polarized relay 17 controlling the clutch 6 between the servomotor and the rudder.

Title: Improvements in or relating to electric circuit breakers
IPC: H01H33/12
Filed: 1932-03-01
Abstract: 398,249. High-tension switches; arcrupturing in switches. WHITNEY, W. B., WEDMORE, E. B., and BRITISH ELECTRICAL & ALLIED INDUSTRIES RESEARCH ASSOCIATION, 36, Kingsway, London. March 1, 1932, No. 22663/33. Divided on 398,213. [Class 38 (v).] In a circuit-breaker of the kind in which an arc is drawn between a pair of electrodes in a region scoured by a blast of fluid and in which the effective gap between the arcing electrodes first increases quickly to a predetermined value, pauses at that value, and then continues to increase, an additional electrode is separated, or separable, to the predetermined gap from one of the arcing electrodes in a region scoured by a blast of fluid, and takes the arc during the time required for the said pause, and has means serving to connect it to the movable electrode during the time of said pause, but to disconnect it at the end thereof. The gap is defined in the Specification as less than a quarter the diameter of the tubular vent outlet for the blast, but greater than the sparking distance at zero of the a.c. cycle. The fluid may be liquid, vapour, or gas. In Fig. 1, an additional electrode 15 in the form of a ring surrounds with clearance the movable electrode 19 which is engaged by a spring-pressed brush 18 secured conductively to the ring 15, which may be of mutually-insulated sectors of 90‹ or less. When 19 is lowered from the throat of the casing 10 forming the fixed contact, a blast of fluid from the pipe 20 escapes from the vent 11, scouring the products from the arc struck between 10, 19. When 19 passes below 15, the arc is transferred to the latter and remains fixed in length while the electrode 19 continues its stroke in contact with 18 for a half cycle or a cycle depending on whether the current being broken is symmetrical or asymmetrical. The electrode 19 finally leaves the container 10, but the arc should be extinguished at a current-zero during the pause. In Fig. 2, the additional electrode 21 is movable by means of springs 26 with the movable electrode 29 until the predetermined gap is reached, the action being similar. Where the breakers are operated with liquid they may be partially or wholly filled therewith or immersed in liquid in a tank. The Specification describes and illustrates also the application of the invention to (1) the construction shown in Figs. 3-6 of Specification 398,213, the electrode 52 being solid, however, (2) the construction shown in Fig. 11 of that Specification, (3) a switch generally similar to those shown in Specification 366,998, and (4) the switch shown in Fig. 8 of Specification 378,493. Specification 398,207 is referred to. The Provisional Specification refers to Specifications 278,764, 330,616, [both in Class 38 (v), Electric switches &c.], and 375,309.

Title: Improvements in electric contacts
IPC: H01H50/54
Filed: 1924-10-01
Abstract: 240,996. Siemens Bros. & Co., Ltd., and Humphries, H. E. Oct. 1, 1924. Metering systems.-Relay contacts of the make-before-break type are made with a sluggish intermediate spring, so that a circuit is momentarily made during forward but not during backward movement of the armature. As shown in Fig. 1, the armature 2 of an electromagnet J on attraction first causes the spring 3 to contact at 8 with the spring 5, after which contact is broken at 7 between springs 4 and 5. Spring 5 has a weight 6 attached to its end which ensures that during the return movements contacts 3 and 5 disengage at 8 before contacts 4 and 5 re-engage at 7. By this arrangement contacts 3 and 5 are momentarily in contact only during the attraction of the armature, and the fleeting current passing through them may be employed to operate a meter M in a telephone system as shown in Fig. 2, the meter being cut in by contacts Z<1> of a relay Z, the circuit of which is completed between contacts 3 and 4 of any of a number of relays J to which it is connected.
