Title: Automatic amusement machine
IPC: A63F5/04
Filed: 1963-03-08
Abstract: 969,303. Chance apparatus. A. J. L. CROMPTON. Aug. 6, 1963 [March 8, 1963], No. 9250/63. Heading A6H. [Also in Division G4] An automatic amusement machine comprises a controller for initiating and controlling a play cycle, a rotary indicating member 18, Figs. 2 and 3, having indicia equal to the number of play stations 12, some or all of the indicia corresponding to the indicia adjacent the play station on a fixed member 17 and contact means 27 which, when the member 18 stops rotating and there is a coincidence of the indicia, cause coin dispensing apparatus to pay predetermined amounts to the winning play station or stations. Any number of players may take part during a play cycle. The indicia may be represented by letters A, B and C or, alternatively, by playing cards. The controller is driven slowly through gearing by a motor and comprises a cylinder having arcuate strips arranged along its length for operating contacts; it may be started automatically upon the insertion of a first coin or run continuously and automatically repeating the play cycle. The controller causes " play " lamps 15 to be illuminated to indicate when the players can insert a coil into the slot 14 of a coin-freed mechanism at the play station of their choice, the coin being arranged to close a set of contacts. After a period of time, the " play " lamps are extinguished, the coin-freed mechanisms de-energized and a spinner, preferably of the type described in Specification 881,803, is energized to give the member 18 a spin on a free-wheel 36; when the member has decelerated to a slow speed, a slow-running motor takes up the drive so as to keep the member spinning at a regulated constant speed for a short period. The motor is then switched-off and the member allowed to coast to a stop. At this stage an electromagnet 51 (see Fig. 5, which is a view from below) is switched on to align a ferromagnetic disc 47-disposed on the shaft 23 supporting the member 18- with another electromagnet which raises its armature into one of the openings 48 in the disc. The member 18 and shaft 23 are then lowered by a tilting arm which acts on a thrust bearing 24 and is actuated by an electromagnet; lowering the member causes a peg 28 disposed opposite each play station to be lowered into a contact-operating position. As shown in Fig. 2, there are three possible peg positions, 29, 30 or 31 and contact positions 32, 33, 34, these corresponding to positions A, B and C. When a contact is operated and providing a coin has been inserted, the word " snap " is illuminated and the coin dispenser operated to pay out the predetermined amount. The coin-freed mechanism and dispenser may be of the type described in Specification 967,344.

As shown, a total hydrocarbon analysis line including a source of carrier air 50, a regulator 55, the catalyst 57 and a valve 51, and a chromatograph analysis line including a source of carrier hydrogen 38, a valve 36 and three columns 32, 33 and 34, are provided. The detector 10 is provided with combustion air from source 50 and hydrogen from the source 38. In the hydrocarbon line, sample air is injected into the carrier stream by valve 51. In the chromatograph line, sample air is injected into the hydrogen carrier stream by valve 36. Column 32 separates the lighter gas, ethane, methane, ethylene, acetylene, Co, CO 2  and air from the heavier gas and valve 36 is switched to pass the lighter gases to column 33 and to vent the heavier gases. Column 33 separates the C 2 - hydrocarbons and CO 2 , and the inert gases, air, methane and Co elute quickly through column 33 into the switching valve 37. Valve 37 is operated so as to pass the C 2 -hydrocarbon i.e. ethylene, ethane and acetylene to the detector 10 and the inert gases, air, nethane and Co to column 34. The inert gases and air pass quickly through column 34, and the Co is converted to methane by a catalyst 46. The valve 37 is again switched to pass the gases from the catalyst 46 to the detector 10. The chromatogram shown in Fig. 2 is then obtained from ionisation current measurements in the detector. In a modification, Fig. 3 (not shown), the combustion air is derived from the output of the oxidized catalyst 57, the sample air is derived from the carrier gas source, and the catalyst 46 is connected between the output of valve 37 and the input of the detector 10. Then the catalyst 46 converts Co 2  into methane, and ethylene and acetylene into ethane.
