Title: An improved coin-freed device for playing a game of skill
IPC: G07F17/32
Filed: 1927-11-24
Abstract: 305,309. Hart, W. Nov. 24, 1927. Games of skill.-A coin-freed device for playing a game of skill comprises a race track around which one or more miniature objects is or are propelled, a controlling and operating handle, and driving mechanism actuated thereby through an interposed coin to operate the device. In the Figure is shown a plan view of the device with the race track removed. A model hare 3 and hound 4 are respectively mounted on radial arms 5, 5<a>. The arm 5<a> may be rotated by gear wheels 9, 10. link 12, slidable bar 11 and a press button 17 which acts by thrusting an inserted coin 16 against the end of the slidable bar. A spring 14 returns the mechanism after release of the press button. The arm 5 carrying the hare 3 is caused, to move in advance of the arm 5<a> by a pawl 32 thereon which abuts against a leaf spring 33 carried by the arm 5. A stop pin 34 fixed to the arm 5<a> prevents the hare from moving too far from the hound. When the hound is nearing the winning post the pawl 32 rides over a guide 35 and is moved from contact with the leaf spring 33 to allow the hound to overtake the hare. In using the device, a coin is inserted and falls into a slot 15 in the end of the slidable bar 11, but is temporarily prevented from falling through by a bracket 21. The press button 17 is now pressed in and the hound and hare are caused to move round the track. When the hound is near the winning post, a depending rod 24 moving with the hound engages a cam 22<a> and rocks a spring-pressed lever 22. If the press button 17 be liberated at the correct instant viz. when the hound is at the winning post, the outer end of the lever 22 will be situated beneath the coin and, when the liberated coin falls through its slot, will deflect it to a shoot for return to the player. If the press button be liberated too soon or too late the lever 22 does not intercept the coin which then remains within the casing. The return movements of the hare and hound are controlled bv a bellows 30.

Title: Improvements in or relating to the electrolytic refining of metals
IPC: C25C3/08
Filed: 1923-12-20
Abstract: 208,714. Aluminum Co. of America, (Assignees of Hoopes, W., and Frary, F. C.). Dec. 21, 1922, [Convention date]. Aluminium and other metals, obtaining.-In a process for refining impure metals such as aluminum alloys the electrolyte is of greater density than the deposited metal and of smaller density than the alloy so that the anode, electrolyte and cathode form successive layers, the process being carried out in a furnace similar to that described in Specification 208,715. A crust consisting at least in part of frozen bath material is formed above the cathode continuous with the heat-insulating side surface,s of the furnace to minimize volatilization and heat loss. The electrolyte consisting of fused fluorides is treated from time to time to prevent undue freezing of alumina and consequent impairment of the mobility of the alloy or excessive formation of crusts. This may be done by auxiliary electrolysis with carbon anodes from time to time or simultaneously with the main electrolysis. A suitable anode comprises a carbon disc 50 in which is screwed a carbon stud 51. An iron terminal secured to a tube 53 is screwed to the stud 51. The tube 53 is secured to an insulating support 57 surmounted by a chamber 51 provided with water supply and exit pipes 55, 56 respectively. A refractory insulating coating 58 is provided to prevent contact with the aluminium layer. Alumin'um is deposited into the aluminium layer or into this and the alloy according to the voltage of the auxiliary anodes. Alternatively the alumina content may be reduced by first removing the aluminium layer, then removing a part of the electrolyte, and replacing it by alumina free material. The alumina may also be removed in the cell by removing the aluminium layer and reversing the connections, the carbon cylinders which normally serve as cathode connections now serving as anodes. The electrolyte may consist of cryolite together with barium or other fluoride which serves to increase the density.

Abstract: 1,049,095. Digital computers. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. Aug. 14, 1963 [Aug. 25, 1962], No. 32112/63. Heading G4A. In a computer operative under the control of clock pulses, in which a data transfer operation can be effected between the computer store and a peripheral unit, the arrangement is such that when a peripheral unit requests attention, the supply of clock pulses to the parts of the computer other than the store is temporarily interrupted so that the operational state of the programme control unit and arithmetic unit is retained until communication with the peripheral device has been completed. As shown in Fig. 1, a computer comprises a store 3 having an associated address register 5, data register 4 and store control unit 14; an arithmetic unit 1; a programme control unit 2; a peripheral unit in the form of a magnetic tape unit 11; and clock pulse generator 10. When the tape unit 11 requires attention, it sets a flip-flop 13 thereby (1) blocking an amplifier 8 to cut off the supply of clock pulses to the arithmetic unit 1 and programme control unit 2, (2) blocking gates 18-20 between the units 1, 2 and the store 3 and (3) enabling gates 21-23 between the tape unit 11 and the store 3. The computer programme data in the data register 4 is temporarily stored in a special location in the store after which an address from the tape unit 11 is effective in the address register 5 (in the case of data input to the store) to write a data word from the tape unit 11 via the data register 4 into the store 3. If the computer can perform a complete store cycle including read-out, operation and writing within a single clock pulse, the need for the temporary storage of the data from the register 4 is obviated. There may be a plurality of peripheral units, including for example typewriters or punched cards, scanned sequentially.

Abstract: 1477930 Printing from developed electrostatic images CANON K K 19 July 1974 [23 July 1973] 32128/74 In a method of transferring a toner image e.g. a developed electrostatic image from an image carrier, e.g. a photoconductive drum, to a transfer medium, e.g. a copy sheet, uniform charges of the same polarity are applied to the image carrier and the transfer medium prior to transfer. In the embodiment of Fig. 4, negatively-charged toner forms a pattern on insulating layer 1c of photoconductive drum 10, which receives an overall negative charge from corona-discharge device 16. The transfer paper P receives an overall negative charge from corona-discharge device 22, and induces a positive charge on conductive roller 19 preferably the charge on paper P is at a lower potential than that on drum 10, and is controllable through grid 22. This potential difference will cause toner to transfer across to paper P and may be assisted by application of transfer voltage to roller 19. The separation of paper P from roller 19 is effected by a mechanical pawl (23), Fig. 3 (not shown) or by coronadischarge device 24 which carries A.C. or a voltage of opposite polarity to the attraction force.
