Title: Apparatus for playing a guessing game
IPC: A63F9/00
Filed: 1961-08-05
Abstract: 941,418. Chance apparatus. A. PAVESI. Aug. 5, 1961, No. 28523/61. Heading A6H. Electrical apparatus for playing a guessing game comprises a drum 2 mounted on a shaft 5 for rotation therewith, inside a casing 1, and inscribed around its periphery with five different symbols. One player selects a symbol and " sets " the apparatus accordingly, by depressing the handle 16 until the projection 17 engages the recess 4 on the drum, and then rotates the shaft until the symbol selected registers with an observation window 15 in the casing 1, simultaneously bringing a metal rod 12 into registration with one of five pairs of contacts 13 on the base of the casing. The handle 16 is then depressed further, against the action of spring 8, until the said rod bridges the gap between the contacts, thereby completing a circuit containing an electromagnetic fastening element 11 and a pilot lamp 20, whereupon the bolt 10 of the locking element is urged against spring pressure to engage in a recess between two collars 9 on the shaft 5, and the pilot lamp lights up. The apparatus is then " set " for the remaining players to try and guess the symbol chosen. Each player is confronted with a set of five push-buttons, each inscribed with a symbol corresponding to those on the drum 2, and each included in two circuits, one to the pilot lamp 20, locking unit 11 and a pair of contacts 13, and the other to one of five lamps 21, these latter lamps again being marked with symbols corresponding to those marked on the drum and on the push-buttons. The pushbuttons are normally spring-urged towards the position in which they close their respective circuits to the lamp 20 and locking unit 11, but when depressed break this circuit and complete that to the corresponding lamp 21. Thus the selection of a symbol on the drum 3 and the consequent setting of the apparatus decides which pair of contacts 13 and which pushbutton 23 is to be included in the circuit to the locking unit 11 and pilot lamp 20, and depression of this particular push-button results in the circuit to the lamp and locking unit being broken and that to the appropriate lamp 21 being completed instead. The pilot lamp is therefore extinguished, and the shaft 5 released. If any other push-button is depressed, the corresponding lamp 21 is illuminated, but no other change in the apparatus takes place. The apparatus is supplied with current via fuses 31, transformer 29 and switch 30. Score indicators 34 manually operated by knobs 35 are provided adjacent each playing position.

An indicator board comprises a case 1, containing lamps 3, and having a number of apertures in its front panel, each aperture being opened or closed by a shutter 4 carried by a plunger which is axially movable in a soft iron core i carrying a coil D. The apertures may be formed as letters, signs or numbers. The plunger consists of a pair of permanent magnets A, B interconnected by a rod C of non-magnetic material, the magnets being so arranged that their ends a and b are of the same polarity. The arrangement is such that if impulses of one polarity energize an electromagnet it clears an aperture if that aperture is not already cleared by a previously applied impulse, impulses of opposite polarity closing the aperture if not already closed. The indicator may be used with an accounting machine, Fig. 5, the switch 11 controlling the supply of D.C. to one of a plurality of relays 15 controlled by a distributer 13. The D.C. is also fed via a reversing switch 12 and a distributer 14 to one of the electromagnets of the indicator board as selected by distributers 13, 14. The distributers 13, 14 and the reversing switch 12 are controlled by the accounting machine.

Title: Improvements in or relating to automatic inspection and gauging machines
Inventor: LOXHAM JOHN
IPC: B07C5/08
Filed: 1955-11-07
Abstract: 805,129. Sorting by gauging. SIGMA INSTRUMENT CO. Ltd. Feb. 7, 1957 [Nov. 7, 1955], No. 28653/55. Class 106 (2). An automatic inspection machine for workpieces V having external surfaces which include a surface of revolution has means 31-39 for rotating the workpieces at one of two gauging stations A, B to inspect the truth of the workpiece surface about the axis of revolution, and also means 5, 7; 72, 73 to feed the work-pieces to and from the stations A, B and control mechanisms 68, 97, 99, responsive to the results of gauging at each station for separating the workpieces into acceptable and unacceptable classes. Workpieces V, e.g. valves, are fed to a a shoot 1, where a timed mechanism 19-29 allows them to fall one at a time into the feeding mechanism 5, 7, which holds the stems of the valves and carries them forward to the gauging station A. Here each valve is received in notches 16 in posts 15 and held between a centre 31 and a pad 39. A motor 32 revolves the valve and if the stem S is not true, a feeler 41 is displaced, touches one of two contacts 44 and makes a circuit between the terminals 46 of a relay 45 and through a solenoid 50, thus operating a gate 68 in the discharge passage 61 from the gauging station A. This circuit is held during one revolution of a cam 49 which operates in relationship with the feeding mechanism 5, 7. Another timed cam 52 makes and breaks a circuit through a solenoid 55, thus actuating the movement of the pad 39 only when a valve is or should be present in the notches 16. A safety device is also fitted to prevent operation of the gauge 40 should a valve not be present. After gauging, the feeding mechanism 5, 7 grips the stem and returns until the valve is above the opening 61, when the grip is released and the valve falls either to the gauging station B or is rejected. The operation of the station B and feeding mechanism 72, 73 is similar to that of the station A and feeding mechanism 5, 7, except that the diameter of the head H is tested and if too large the valve falls into a " rectifiable " box 104, if undersize the valve falls into a " reject " box 102, and if within the required tolerance limits into box 106. The passages to these boxes are covered by deflectors 99, 97, operated by solenoids 93, 92, respectively. Pneumatic gauge heads may be employed instead of electrical gauges. Specifications 594,420 and 594,450 are referred to.
