[Class 117.] Apparatus for sorting articles, such as beans, according to colour comprises means for moving the articles in succession past a photo-electric cell, means controlled by the photo-electric cell for positively displacing the articles from the moving means and means for rendering the displacing means inoperative except when each successive article is in functional relation to the photo-electric cell. As described, the displacing means consist of a push rod 16 which is actuated by a solenoid 17 to push out of the succession of articles those of a colour darker than the standard The solenoid is in circuit with a gas discharge valve 24, the grid voltage of which is controlled by the photo-electric cell 12 through two cascade-connected amplifying valves 22, 23 and a filter consisting of induction coils 38, high resistances 37 and capacity 39. The system is supplied with power from two sources 25, 26 of direct current at voltages, for example, of 500 and 125 respectively, and the filter acts to damp out the ripple variations of the alternating current for heating the filaments of the amplifiers and discharge valve. In order to time the energisation of the solenoid and to interrupt the current in the valve 24, a rotary switch comprising a cylinder 27 of insulating material and conducting strips 28 co-acts with terminals 29. The switch is geared to the feeding device which consists of a hollow disc 3 with peripheral apertures 10 and connected to a suction pipe 9. The disc is rotated through a mass of the articles in a hopper 1, and a stripper 20 detaches the standard articles.

Title: Circuitry for an electronic timepiece
IPC: G04G3/02
Filed: 1976-06-22
Abstract: 1534910 Electronic timepieces DAINI SEIKOSHA KK 22 June 1976 [9 July 1975]  25893/76 Heading G3T In an electronic timepiece, a standard time signal for display is obtained by frequency division of oscillator pulses using a multi-stage divider. The output of at least one stage of the divider is passed through a delay circuit, gate and switching circuit (a level shifter) to energize circuitry of the timepiece with a predetermined voltage. The gate also receives the divider output. As shown, the output of quartz oscillator 1 is shaped by inverters 26, 27 and fed to flip-flop FF1 forming the first stage of divider 8. A D-type flipflop 9 which includes FETS and inverters receives an input from FF1 and the final stage of the divider 8. Outputs from the delay circuit 9 and divider 8 are fed via NAND gate 14 to an FET 15 i.e. a switching level shifter, that feeds circuitry 18 via inverter 19. In an alternative, the delay circuit 9 may be connected to one or more of the divider stages. The system is such that the output of level shifter 15 is substantially unaffected by distortions occurring in the oscillator output.
