Title: An improved coin freed apparatus for playing a game of skill
IPC: G07F17/38
Filed: 1937-11-09
Abstract: 502,270. Coin-freed game apparatus. TURRALL, W. Nov. 9, 1937, No. 30706. [Class 27] [Also in Group XV] A coin-freed apparatus for a bowling game comprises a plurality of targets adapted to be displaced individually by missiles and when displaced to close the circuits of electrically operated score indicating means, the score indicating means comprising a number of indicators and the targets being arranged in corresponding sets, means being provided to operate automatically a gameended notifying device when an indicator reaches a predetermined or maximum score indication. The balls 13, 14, Fig. 1; after release by coil-freed mechanism, which also energizes an electromagnet to allow the indicator mechanism to zeroize, are taken from a trough 63 and rolled up the table 1 and ramp 22 to drop upon spring-supported targets 2 arranged in triangular formation. The targets have central illuminated discs of different colours so as to divide the targets into four groups associated respectively. with four indicators R, G, A, B, Fig. 3, behind a vertical glass panel 24. When a ball depresses a target an electric contact behind the target is momentarily closed and one of a number of lamps 23 is illuminated as described below, in the corresponding indicator, the indicator B (losing indicator) being also operated when a ball fails to strike any target. The latter operation is effected by a switch as the ball returns over and depresses a flap 21. The balls are continually. returned to the trough 63 for re-use until the player has reached a prize-winning score or has made a predetermined number of losing shots as registered by the indicator B. To effect an indication, the closure of a target contact causes a corresponding electromagnetically-operated switch to rotate and to advance a series of contact arms over contact studs, and on repeated striking of the target to illuminate successively the lamps 23 of the corresponding indicator. At the end of the switch movement a further contact arm on the switch closes a circuit to give an audible and a visible warning that all the lamps of one indicator are illuminated. The circuit of the source of supply for the operating means of the score indicating devices is also broken. To prevent one throw of a ball from operating an indicator more than once, a relay magnet associated with the driving magnets of the rotary switches opens the target contact circuits at each indicating movement of a switch, the normal circuits being re-established when a ball running down the return shoot 15 closes a relay cut-out switch. The balls in passing to the return shoot 15 and rocking the flap 21 close the circuit of a magnet which then momentarily withdraws its armature from a ball-obstructing position across the shoot and allows the previous ball to proceed to the player.

Title: Improvements in or relating to forging presses
IPC: B30B15/18
Filed: 1925-12-07
Abstract: 244,124. International General Electric Co., Inc., (Assignees of Allgemeine Elektricitõts-Ges.). Dec. 6, 1924, [Convention date]. Forging-machines. - A forging-press indicator having a pointer moved over a scale by the pressram comprises a rack moving with the ram, a pinion meshing with the rack, and a screw-device for transforming the rotation of the pinion into the liner movement of the pointer. When applied to an electrohydraulically driven press, the indicator device may operate a switch to cut out the driving motor when the press-ram reaches a predetermined position, and the switch may be so arranged as to reduce the revolutions of the motor before such position is reached. The cross-arm T of the press-ram carries a rack Z gearing with a pinion R, the motion of which is communicated by bevel gearing to the vertical screw of the indicator device H, the screw working in a nut carrying a pointer C moving alongside a scale S. The motor-control device comprises two pivoted levers E<1>, E<2> held against adjustable stops P by springs F, and normally in contact with a contact-plate V on a two-armed pivoted lever K. When the press-ram approaches the end of its stroke, the stop A on the indicator actuates the lever K and lifts the plate V out of contact first with the lever E<2> and then with the lever E<1> the connections of these levers and the plate V with the motor-control being such that the lever E<2> reduces the speed of the motor, as by switching in resistances, and the lever E' stops it.

Patent GB-173657-A (GB)
Title: Improvements in thermally controlled circuit interrupters
IPC: H01H87/00
Filed: 1920-11-02
Abstract: 173,657. Igranic Electric Co., Ltd., (Cutler-Hammer Manufacturing Co.). Nov. 2, 1920. Mercury cut-outs. - A container, consisting of a bulb and a restricted tubular extension, is filled with a liquid conductor such as mercury, which completes contact between two electrodes. A heating-coil is wound round the extension, and within this coil the diameter of the extension is enlarged. An overload causes vaporization of the liquid and the vapour formed tends to push the liquid above it out of the tube into the bulb, thus interrupting the circuit between the electrodes. The inner diameter of the tube is so chosen as to prevent reflux, whereby the circuit would be re-made, but is sufficient to permit of the liquid overcoming capillary action and vapour pressure when the temperature has fallen to a predetermined value. In the arrangement shown in Fig. 1, the coil 6 heats the enlarged portion 14 of the tubular extension 10 of the control element 5. The electrodes 11, 12 are sealed in the outer ends of the container and are connected by the mercury 13 which fills the extension and part of the bulb 9. The remainder of the container is preferably evacuated. The support 7 is divided into similar and interchangeable sections 15, 16. The container and coil are disposed axially within this support. The halves 15, 16 are clamped together and to the base 8 by means of the studs 24, 25, which also serve as terminals for the heating-coil, and the support 7 is provided with enlarged portions 31, 32 to receive the studs and to provide a flat surface where the support 7 abuts on the base 8. End caps 35, 36 are preferably cemented to the container and are in permanent connection with the electrodes 11, 12. These end caps fit into the bore of the support 7 and are kept in position by conductive clips 37, 38, which are clamped to terminal bolts 28, 29. The coil 6 and the element 5 are both surrounded bv the support 7, an arrangement whereby the inverse time element of the device is secured. In moderate overloads, the support conducts away much of the heat from the coil and little is radiated to the tubular extension. A heavy overload, however, raises the temperature of the coil to such an extent that a relatively large part of the heat is radiated directly to the element and a comparatively early response is effected. The support may also be adapted to retain the heat developed by the coil so as to delay re-establishment of the broken circuit. Operative characteristics may be varied by, for example, altering the contour of the control element or by varying the nature of the coil or its relative position with regard to the support and the tubular extension. The control element and coil are both radially removable for inspection, the former by removing the clip 37, the latter by removing the front section 16 of the support. In a modification, the support is formed integral and the upper annular shoulder 18 omitted so as to permit insertion of the heating- coil from above.

Title: Electron image storage tube
IPC: H01J31/60
Filed: 1949-12-02
Abstract: 668,352. Cathode-ray tubes. STANDARD TELEPHONES & CABLES, Ltd. Dec. 2,1949 [May 14, 1949], No. 31021/49. Class 39 (i). An image or pattern is recorded on the mosaic 15 of a storage tube, Fig. 2, by a scanning beam 19, the mosaic then being flooded by a beam 22 from a second electron gun which is decelerated by grid 16 so as to be reflected from the mosaic in accordance with the stored charges thereon, finally striking a fluorescent screen 29 to reproduce the pattern. The mosaic is formed of microscopic quartz particles coated on a metal backing plate 14, and, having a secondary emission factor less than unity, they acquire a negative charge pattern according to the signals modulating the high-velocity scanning beam 19. The broad beam 22 from the second gun 21 is bent by deflecting plates 26, 27 and focused by coil 23 on to the mosaic through the decelerating grid 16, so that some electrons are reflected from the mosaic according to the electrostatic charge pattern. These are further bent, and impinge on the fluorescent screen 29. In the modification of Fig. 4, the storage element consists of a thin glass film 34 with a mesh electrode 35 attached to one side. The recording beam 37 scans from the other side through a grid 36, producing a charge pattern on the mesh electrode, secondary electrons emitted from the glass film being collected by the grid. The second beam 45 acts in a corresponding manner'to the beam 22 in Fig. 2, but in the Fig. 4 arrangement the fluorescent screen is replaced by a series of output targets 50. Instead of employing a single continuous storage element in the form of a glass film, the recording charges may be effected with a series of individual units, Fig. 5 (not shown). In all forms described, the record on the storage element may be erased by altering the electron velocity of the scanning beam.
