Filed: 1961-12-19
Abstract: 948,399. Coating apparatus. MATHIASTHESEN WERFT WISMAR VEB. Dec. 19, 1961, No. 45432/61. Heading B2B. In an automatic spray coating apparatus plates 1 are moved by rollway 2 through gantry 14 comprising the means for controlling the operation of spray guns 4 and 5 corresponding to the width of the plates 1 and then through spray cabin 3 in which the spray guns are reciprocated transversely to the plates 1 and are driven by motor 10. In gantry 14 is a reversing switch 15 which is vertically adjustable by means of a threaded spindle 17 driven by servo motor 16, the direction of rotation of which is governed by switch 15. In gear box 26 are valves 22 and 23 for controlling the supply of compressed air to the spray heads 4 and 5, which valves are movable along a threaded spindle 21 by servo motor 20 and are opened and closed by cam shafts 18 and 19, the number of such shafts being equal to the number of spray heads. The cam shafts, the revolution of which is equivalent to an upward or downward movement of the spray heads, have a continual reduction in the cam dwell along the length of the shafts such that at one end of the shafts the valves will be open for the maximum possible time and at the other end the valves will be open for the minimum possible time. The operation of the motors 16 and 20 is controlled by switches 29 and 30 which are actuated by the plates 1. In the rest position switch 29 is "off" and switch 30 is "on". If the entering plate is narrower than the preceding plate, the reversing switch 15 will be above the upper edge of the entering plate. When switch 29 is closed by the entering plate and before switch 30 which has been closed after the passage of the preceding plate, is opened by the entering plate, current is supplied to motors 16 and 20 and the reversing switch 15 is moved down until feeler 15a strikes against the upper edge of the plate and opens switch 31 which breaks supply of current to motors 16 and 20. During this time the valves are moved into a position on the spindle 21 such that they are in a position with respect to the cam dwell corresponding to the width of the plate. If the entering plate is wider than the preceding plate the feelers 15a and 15 are pressed in by the entering plate thus opening switch 31 and closing switch 32. When switches 29 and 30 are closed the switch 15 is moved up until feeler 15b is opened and the valves are moved into an appropriate position. Compressed air is supplied to the valves 22 and 23 by conduit 27 as the plate passes over lever 25 which opens valve 24 to which compressed air is fed from a supply main.

Abstract: 954,261. Automatic speed control. GENERAL ELECTRIC CO. Dec. 20, 1961 [Jan. 3, 1961], No. 45638/61. Heading G3R. A desired final speed for turbine 16 is preset in line 8, the rate of acceleration to this final speed being set by adjusting variable drive 5. This affects the time necessary for motor 4 to move potentiometer 6 to the final speed setting. Summing device 2 supplies an error signal which is amplified by saturable reactor 3 to operate motor 4 and drive potentiometer 6. The movement of the slider arm on potentiometer 6 is such as to cause it to move to a position wherein the signal over feedback line 7 balances the speed signal in line 8, whereupon a zero signal from summing device 2 causes motor 4 to stop. The reference signal supplied to summing device 11 thus gradually increases with time at a constant rate, as determined by the setting of drive 5. The increasing reference signal passes through summing device 25 and is amplified in amplifier 12, whose gain is greater in the vicinity of its zero input condition. The amplified signal operates motor 13 driving a lead screw which actuates a hydraulic relay pilot valve 14, which in turn actuates a main turbine valve 15. The actual turbine speed is compared with the desired signal by a feedback loop comprising tachometer generator 18, rectifier 19, and filter 20 having a leading characteristic which counteracts the lagging characteristic due to the time constants of elements 12-17. To further offset the time lag between movement of valve 15 and response of turbine 16, the valve movement provides a feedback signal, through differential transformer 22 and demodulator 23, to the summing device 25. Specification 898,108 is referred to.

Abstract: 1,113,870. Lamp failure alarm; vehicle signalling systems. TUNG-SOL INDUSTRIES Inc. 28 Oct., 1965 [30 Oct., 1964], No. 45679/65. Headings G4N and G4Q. A vehicle signalling system includes a relay with two windings so connected in the circuit that failure of a signal lamp upsets the current balance in the relay allowing it to energize giving a lamp failure indication. As shown in Fig. 3, actuation of switch 48 to signal a left turn, say, completes the circuit between flasher contacts 16 and indicators 54L, 56L via relay winding 28, and between flasher contacts 16 and pilot lamp 60 via relay winding 32, the ampere turns of the two windings being equal. Failure of one of the lamps 54L, 56L allows the relay to energize, opening contacts 26 in the pilot lamp circuit. Pilot lamp 62 similarly monitors right-turn lamps 54R, 56R. For emergency operation the switch 48 is actuated to the leftturn position, and emergency switch 92 is actuated completing the right-turn circuit. Both pilot lamps are thus in parallel maintaining the current balance in the relay windings. For daytime use, switch 58 is closed, connecting an extra lamp filament in the rear turn indicator lamp 56L, 56R. Current balance in the relay is maintained by also switching in an extra filament in the corresponding pilot light. In an alternative arrangement, Fig. 4 (not shown), the front indicator lamp may be connected to one relay winding, and the rear one to the other, the pilot lamp being connected directly with the flasher via the relay contact 26. The system also includes a brake light switch 42 for actuating the rear lamps.
