Title: Automatic coin-operated amusement machine
IPC: G07F17/38
Filed: 1965-08-02
Abstract: 1,087,361. Coin-operated amusement machchine. N. S. CROMPTON and J. E. CROMPTON. July 21, 1966 [Aug. 2, 1965], No. 32941/65. Heading A6H. An automatic coin-operated amusement machine comprises a substantially vertical panel 11 having four coin slots (not shown) arranged at the -top thereof so that coins inserted in the slots are allowed to fall vertically down the surface of the panel; at various points over the area of the panel springy pins (not shown) project from the surface; the panel contains eight openings 12 to 19 each of which is obscured by a metal plate 20, e.g. in the shape, of a cup, which is parallel to and spaced from the surface of the panel so that a coin which appears to fall into the cup will fall through the opening and pass down a steeply sloping chute (not shown) behind the panel; the passing of a coin through an opening actuates a switch associated with that opening; two ramps 23 and 24 lead to a pair of coin receiver chutes 26 and 27 along each of which are spaced four tubular coin receivers capable cf holding different numbers of coins and closed by a slide which is connected to an electricmagnetic actuator. These actuators are each in circuit with a switch associated with one of the openings so that when a coin passes through an opening in the panel the switch associated with that opening is actuated and so energises the electromagnetic activator controlling the slide on the associated coin receiver. The coins in the receiver are released and fall on to a coin tray from which the player can collect them. If the coin used does not fall into one of the "cups" it reaches one of the ramps 23 and 24, and falls on to one of the chutes 26 and 27 and slides down the chute into the first coin receiver which has room to take it. If all the coin receivers are full the coin falls into the coin tray and the user may recover it. The coins which fall into the "cups" and produce wins for the users fall into a coin box inside the machine casing and are retained.

Title: A method and device for trueing grinding wheels
IPC: B24B53/07
Filed: 1937-11-29
Abstract: 508,681. Grinding. REISHAUERWERKZEUGE AKT.-GES., and RICKENMANN, A. Nov. 29, 1937, Nos. 32945/37 and 32061/38. [Class 60] A multi-ribbed and grooved tool for forming or trueing grinding-wheels for producing screwthreads, and having therein a longitudinal recess, has the recess so formed that the tool is continuously driven by the grinding-wheel during the trueing operation ; the tool shown in Fig. 1 is made in two or more co-axial parts 12, 12<1> with the respective recesses 14 displaced angularly and the tool shown in Fig. 5 has a spiral recess 36 of angular width less than the angular displacement between the ends of the spiral. In the production of a tool, according to Fig. 1, the two parts 12, 12<1> are clamped, with the recess 14 in line, on a sleeve 10, Fig. 2, slidably but non-rotatably mounted on a mandrel 2, which is mounted on centres 3, 4 on a slide 8. The mandrel is driven at one end by a dog 9 and the opposite end has thereon a sleeve 17, prevented from rotating by a dog 16<1> and having keyed thereon a counter-cam 18 ; the cam 18 co-operates, through balls 23, with a cam 11 secured to the sleeve 10, to feed the tool parts 12, 12<1>, &c. axially backwards at the same rate as the slide 8 is fed forwards. By this means a groove is ground in the tool by a grinding-wheel 1, and when the recess 14 arrives opposite the wheel, the cams 11, 18 under the action of a spring 20, allow the sleeve 10 to move forward to the extent of one pitch of the grooves in the tool 12, 12<1>, so that the next groove is ground. In forming a tool with a spiral recess 36, Fig. 5, the arrangement is generally the same as described above, but the cam 18 is rotated slowly by a rack-bar 33 moved by a block 34, which engages a recess in an inclined guide-bar 35, so that when one groove is ground, the passage from that groove to the next does not take place exactly after a . complete revolution of the tool, but is displaced circumferentially to an extent depending upon the spiral shape of the recess 36. The movement of the cam 18 may be obtained by differential gearing. The tools 12 are provided with irregularly spaced grooves 38, which may be of spiral form. Specifications 417,771 and 462,575 are referred to.

Abstract: 1,005,539. Semi-conductor devices. ENGLISH ELECTRIC CO. Ltd. Dec. 11, 1961 [Sept. 27, 1960], No. 33106/60. Heading H1K. An electrical component is at least partially immersed in a volatile coolant liquid in a sealed casing. Baffles or other means are arranged within the casing to reduce the tendency of the liquid level to change when the casing is displaced from its normal operating position or subjected to acceleration forces. In the embodiment four series-connected silicon diode rectifiers 1-4 mounted coaxially in a steel tube 16 with dished steel end plates 17 are cooled by a volatile halogenated hydrocarbon, e.g. trifluorotriohloroethane. The tube is evacuated and then filled with sufficient coolant to cover the diodes when the tube axis is horizontal via tubule 29 which is then sealed off. Dangerous fluid pressures within the tube are prevented by a burstable metal diaphragm 24. Surge of fluid due to rapid accelerations which might uncover one of the diodes is restricted by baffles and/or by the provision of hollow resilient balls (not shown) fixedly mounted in the vapour space above the coolant. In operation the coolant near the diodes evaporates and condenses in cooler parts of the liquid or on the parts of the tube bounding the vapour space which may be finned and cooled by a forced air draught. Components . associated with the rectifiers such as resistors and capacitors may also be housed in the tube.

Abstract: 447,424. Screw propellers. RICE, R. M. A., 42, Lowlands Road, Harrow, Middlesex. Nov. 11, 1935, No. 33499/34. [Class 114] A variable-pitch screw propeller has two blades altered in pitch as a result of a relative rotation of the hub on its shaft, the drive being effected by a hydraulic coupling which in addition to the transmission of torque is itself controlled by the centrifugal force of the fluid in the coupling and so produces the relative motion. The boss 3 of a screw propeller is freely mounted upon the shaft 1 and is coupled to an arm 18 fixed thereon by means of a rod 17 of a piston 12 operating in a cylinder 14 having at its other end a closure cap 15. The blade roots are mounted in hub sockets 4 and each is provided with a bevel wheel 6 geared to a common wheel 5, whereby relative rotation of the hub and shaft caused a pitch adjustment. During rotation the closure member 15 under centrifugal action operates on the liquid in the cylinder 14 and on change of speed effects a movement of the piston 12, and thereby the position of the hub relative to the shaft. The liquid movement in the cylinder 14 may be damped by providing a restriction 16a between the cap 15 and the main body.
