Title: Improvements in games of chance
Inventor: WHITTAKER ERIC
IPC: G07F17/34
Filed: 1962-12-20
Abstract: 956,223. Chance apparatus. WHITTAKER BROS. (AMUSEMENT RIDES) Ltd. Feb. 5, 1963 [Dec. 20, 1962], No. 48253/62. Heading A6H. [Also in Division G4] An unattended roulette wheel, continually put into play at timed intervals, is housed in a casing which provides a number of stations, each with an array of coin slots 3, whereby a participant may place a stake and thereby qualify for prize money which is dispensed at his station should his stake prove successful. The insertion of a coin into a coin slot operates a contact to cause an associated relay to lock up and prepare a circuit to a prize delivery solenoid, which circuit is completed should the roulette ball enter a partition of the wheel particular to the selected coin slot. The ball may complete the circuit by means of operating or bridging contacts in the partition of the wheel. The sequence of events and the amount of prize money dispensed may be controlled by a uniselector but is preferably controlled by cam mounted on a common shaft. A sign is illuminated to call for stake money, the wheel is turned to put the ball into play, and after a time sufficient for the ball to settle, a relay is energized to connect up the contacts of the wheel connected by the ball. Depending on which contacts are connected on the wheel the cams then selectively dispense two, three, or four coins as prize money to as many stations as record the deposit of a winning stake. Each coin slot has two lamps; one to mark the slot in which a stake has been placed and the other to indicate the slot which qualifies for prize money. Prize money is dispensed from coin tubes filled with the received stake money which is raised on an endless band elevator to reach the top of the tubes. When the tubes are full the money overflows into a cash box.

Title: Process for distilling sea water
IPC: B01D1/28
Filed: 1965-11-15
Abstract: 1,069,659. Distilling sea water. J. E. POTTHARST, Jr. Nov. 15, 1965, No. 48437/65. Heading BIB. The formation of scale on heat exchange tubes 24 in a sea water evaporator 13 is prevented by regulating the temperature of the heat exchange surfaces to within the range 95‹F to 120‹F, removing concentrated sea water through pipe 41 at a rate such as to maintain a concentration ratio (feed rate / removal rate) of 1.2 to 1.7, operating under low pressure, and maintaining by means of a rotor 19 the velocity of circulation of the sea water up through the heat exchange tubes 24 and down through the central passage 18 such as to prevent vapour being evolved within the heat exchange tubes. Vapour formed at the liquid surface is withdrawn by compressor 27 through a moisture separating wall 26 and via passage 64 to a vapour chest 31 accommodating the heat exchange tubes 24. The vapour is condensed in this chest and the distillate is withdrawn to a tank 33, any vapour evolved in the tank being returned through pipe 34 to the vapour chest. Distillate withdrawn from tank 33 under the control of float-controlled valve 38 passes through a heat-exchanger 14 to heat incoming sea water and to a storage tank. In starting up the apparatus sea water is introduced into the evaporator, and automatically controlled valve 16 is closed to prevent the supply of further sea water to the evaporator. Immersion heaters 60 heat the liquid in a tank 61 and supply vapour to the chest 31. As the vapour is condensed in the chest it heats the sea water, the condensed water accumulating in tank 33 passes, with valve 38 closed, to replenish tank 61. As the amount of distillate increase and causes valve 38 to open, flow switch 39 is actuated to open valves 16 and 67 to admit sea water to the vaporization chamber and sealing water to the shaft 28 through pipe 66. Fig. 4 not shown, shows the point at which sealing begins at different concentration ratios and at different temperatures of the heat exchange surface.

Title: Web winding apparatus
IPC: B65H19/22
Filed: 1965-11-16
Abstract: 1,094,954. Winding webs. H. A. MAYNARD. Nov. 16, 1965, No. 48598/65. Heading B6B. In a web winding machine, a web-roll is supported on two parallel rollers 44, 46, at least one of which is driven. A third driven roller 58 is mounted in a vertically movable support 60 pivoted at (54, Fig. 1), and urges the web-roll into the nip of the parallel rollers 44, 46. The web 18 is advanced over and supported by a table 16 provided with adjustable edge guides 20. When the web-roll has reached the required diameter, an extension 146 of the support 60 operates a micro-switch 142. This in turn operates a solenoid fluid valve 138 to cause a blade 130 to sever the web on table 16. Associated with the blade on each side thereof are two paste tubes 160 which serve to spot the web in front of and behind the line of severance. Retraction of the blade 130 operates a microswitch (124, Fig. 1), which after a predetermined time delay operates a solenoid fluid valve (120) of a core inserting mechanism. This mechanism includes a carriage 86 slidably mounted on the table 16. The carriage has a top surface 92 directly below the lower end of a core magazine 42, and a transverse slot 94 which receives a core when the slot is in alignment with the magazine 42. In a working stroke the carriage is moved forwardly by a fluid cylinder operated linkage (Fig. 1) to strap the received core into the bight of the parallel rollers 44, 46. The finished web-roll is ejected by means comprising pusher plates (96, Fig. 6) which extend inwardly from the ends (98) of the slot 94 for a short distance sufficient to abut the finished web-roll and to thrust it out of the winding station and into a discharge shoot 100. With the new core in position in the winding station, the third roller 58 moves down together with the support 60 and its extension 146. Via a linkage 154, a pair of continuously driven rollers 28 mounted on a pivoted arm 36, moves down to engage the web 18 on the table 16 to advance the leading edge thereof to the winding station. At the winding station, a series of guides 74 and 76 positioned in grooves in the rollers 44, 46 and 58, serve to wrap the leading edge of the web around the new core. The guides 76 form parts of arms 78 pivoted at 82 to the support 60, these arms being biased together by a spring 80. As the diameter of the web-roll increases, the arms 78 move apart (Fig. 3). A conventional web slitter may be provided with the winding apparatus.
