IPC: F23G5/44
Filed: 1935-05-30
Abstract: 453,455. Treating refuse. GARCHEY, C. M. L. R. GODILLOT-, 10, Avenue Vion, Whitcombe, Paris. May 30, 1935, No. 15756. [Classes 33 and 111] House refuse is discharged from the house with flushing water through vertical shoots and pipes leading to a collecting chamber 4, which may be common to several houses or groups of houses. Surplus water is siphoned from the chambers 4 to a drain. The solid refuse is periodically withdrawn under suction from the chambers 4 through valved branches 7 and to a main leading to a receiving tank 10 at an incinerating station 9. The suction is produced by a vacuum pump 25 connected to the tank 10. When the suction is cut off, air is supplied to the tank 10 from a compressor to force the refuse up valved pipes 13 to a hydro-extractor 17. The solid matter from the hydro-extractor is delivered to a drying and incinerating-furnace 18. A fan which blasts air into the furnace is connected to the hydro-extractor. Ozonifying apparatus may be connected to the hydro-extractor to ensure oxidation of the gases given off therein. Hot gases discharged from the furnace may be utilized for boiler heating.

Title: Means for detecting prize-winning combinations of symbols in a gaming machine
IPC: G07F17/32
Filed: 1975-04-17
Abstract: 1531754 Gaming machines BELL-FRUIT MFG CO Ltd 18 Feb 1976 [17 April 1975] 15780/75 Heading G4V A gaming machine selected a combination of symbols at random during each game and awards prizes when predetermined winding combinations occur. Detector means 2 provide for each game a four bit binary code signal characteristic of each symbol displayed by the reels on a payline. Each signal is stored in a symbol comparator unit 3. An enable signal 4 then triggers an oscillator 5 which clocks a divide by 32 binary counter 6 which in turn drives three PROM units 7, 8 and 9. A symbol code signal from PROM 7 is fed to all four symbol comparator units 3 and each produces a coincidence signal if the stored symbol and the symbol signal from the PROM are the same, but otherwise produce a zero output signal. The resulting output signals from units 3 are fed to a win comparator 10 and stored therein as a symbol occurrence pattern code. Simultaneously with the signal from PROM 7, PROM 8 feeds an occurrence pattern code signal to the win comparator 10. If this code and the code stored in the win comparator 10 are the same, the latter produces a coincidence signal which enables a presettable counter 11. If there is no coincidence signal oscillator 5 continues to operate and binary counter 6 drives the PROMS so that they produce the next set of output signals corresponding to another possible prize-winning combination. If a coincidence signal is produced counter 11 inhibits oscillator 5 and payment unit 13 is enabled to pay out. A prize value code signal from PROM 9 determines the number of coins paid out by unit 13. When counter 11 is reset to zero oscillator 5 is enabled to read the next set of codes from PROMs 7, 8 and 9. For example a combination such as a bell-bell-bell-cherry may produce one prize corresponding to the three bells and one corresponding to the cherry.

Abstract: 511,090. Photographic shutters. ZEISS IKON AKT.-GES. May 26, 1938, No. 15807. Convention date, July 17, 1937. [Class 98 (i)] The setting of the delay-action mechanism of the shutter is prevented when the shutter is set to " Bulb," Time " or the highest speed instantaneous exposures, and similarly when the delay-action mechanism is tensioned, the setting to these speeds is also prevented. A locking lever 6, Fig. 4, mounted on a pin 5 on the shutter housing can lock the adjustment ring 1 of the shutter by engaging with one arm 8 in a groove 3 on the ring 1. The other arm 9 of the lever 6 can be moved to a position which prevents movement of the tensioning arm 7. When the shutter is set to " B," the arm 8 lies against the thicker wall of the ring 1, and the arm 7 is then prevented from moving to the delay-action tensioning position. Also when the delay-action mechanism is tensioned, the arm 8 lies in the slot 3, and the member 7 prevents downward movement of the arm 9 so that the adjustment of the ring 1 to " B " &c. is prevented. In a modification, Fig. 6, the locking device is arranged outside the shutter. The time adjustment ring 13 is geared through an intermediate wheel 16 and a gear wheel 18, to an exposure indicating disc 17. A sector 19 is rigidly connected to the shaft of the disc 17 so that when the disc is set to " B" &c., the sector projects into the path of a manually adjustable double armed lever 20. When the disc 17 is set to " I," the lever 20 is moved by the handle 22 to tension the delay-action mechanism by striking the winding lever 11 of the ring 13. In the end position, a projection 23 on the ring 13 is disposed in the path of a pin 24 and prevents an adjustment to " B," " T " &c. The lever 20 may be replaced by a slider.

Abstract: 820,282. Burglar and like alarms. CLARKE, M. July 29, 1957 [May 26, 1956], No. 16351/56. Class 118 (1). [Also in Group XXXVII] A vibration-actuated inertia switch assembly (see Group XXXVII) comprises a switch 12, which may be a mercury switch or a snapaction micro-switch, maintained open by a ball 6 balanced on the end of a switch-actuating arm 8, and is provided with setting means having a delay device 15 such that when the apparatus is mounted on a door the door may be closed before the resetting means has restored the ball to its balanced condition. A battery, or other source of electrical supply, 33, is connected in circuit with a main switch 24, micro-switch 12, indicator lamp 23, terminal block 26, wires 27, and alarm bell 25, as shown in Fig. 4. Depression of the end 21 of cranked pin 19 (Fig. 1) compresses spring 18 while the end 20 depresses the actuating arm 8 to open micro-switch 12 and allow the ball 6 to run to a hole in the centre of a dished platform 4 inside container 2. As the spring 18 reasserts itself against time delay device 15 the arm 8 is allowed slowly to rise until the ball 6 seats on a cup 10 on the end of arm 8 and stops further upward movement of the arm. The cranked pin 19 continues to rise till the end 20 is clear of arm 8. If the device is now subjected to vibration the ball 6 falls off the cup 10 and allows the arm 8 to rise fully, enabling micro-switch 12 to operate, thereby ringing alarm bell 25, or other visual or aural signalling device. Instead of lamp 23 remaining lit all the time switch 24 is closed, a contact may be arranged to flash a check lamp, the crank 19 touching it momentarily as it clears the arm 8. Instead of closing a circuit the microswitch 12 may open a circuit, closing a relay operating the warning system. Specifications 419,917 and 538,209, [both in Group XXXVII], are referred to.

Title: Improvements in or relating to controlling means for variable speed power transmission apparatus
IPC: F16H59/24
Filed: 1940-11-13
Abstract: 545,325. Variable-speed gearing. HOBBS. H, F. Nov. 13, 1940, No. 16420. [Class 80 (ii)] A combined throttle and variable speed gear control comprises a member 1 which during the first part of its movement moves the throttle to its fully open position or substantially' so and decreases the transmission ratios while during the second part of its movement the throttle remains fully open while the transmission ratios are increased, means operated by the transmission output speed being provided to decrease the transmission ratios with increase of speed. As shown, a pair of rotary valves 52, 53 control leakage of pressure fluid from a cylinder 50, the piston 60 of which is connected by a rod 62 to the transmission ratio control member of a variable-speed gear. The cylinder 50 is supplied with pressure fluid from an engine driven pump, or otherwise, and the movement of the piston 60 is such that upon increase of pressure in the cylinder 50 movement of the rod 62 causes a decrease in the transmission ratio. Valve 53 is connected by a crank 54, rod 5, and sleeve 1 to the accelerator pedal 6. Valve 52 is connected by a crank 55 to a centrifugal governor driven by the gear output shaft. The interior of the valve 52 is open to exhaust, and the valve has ports 56, 57. Port 56 is in series with a port 58 in valve 53, leading to the cylinder 50, and port 57 is connected to the cylinder 50 by ducts 71, 73 and annular recess 72 round the valve 53. The shape of the port 58 is such that as the valve 53 moves leakage from the cylinder 50 at first decreases and thereafter increases. Port 56 gradually decreases as the valve 52 is moved so that at high speeds of the gear output shaft it nullifies the effect of the port 58 on the cylinder leakage. Further the port 57 is shaped to increase the leakage as the output speed increases and thus increase the transmission ratio with the 'speed. The cylinder may have a hand controlled valve to permit the use of a higher ratio than that given by the accelerator controlled apparatus. Specification 544,936 is referred to.
