Abstract: 1,041,623. Vehicle control. E. WINTER, A. WINTER, E. WAGNER, R. WAGNER, F. KEIM, and L. WAGNER, [trading as FIRMA ERNST WAGNER APPARATEBAU. [June 3, 1964 [June 21, 1963], No. 22961/64. Heading B7N. The speed of a vehicle, which is guided by a photo-electric arrangement, including photo-cells 2 connected via amplifiers 3 to a steering control unit 4, to follow a route defining light reflecting strip 1, is controlled by a speed control unit 8 actuated when the light reflected to the photo-cells is pulsed by interruptions 5 in the guide line. Each cell is connected to a multivibrator 6 which extends the duration of a received pulse and the multivibrators are connected in series with a stepping relay 7 which at each step increases the degree of speed regulation. In a second arrangement shown in chain lines the multivibrators operate a slow to release relay 10 associated with the speed control unit via a cam-operated switch 9 when the vehicle steering mechanism, which is coupled to the cam switch, is set for straight running. Thereafter when the vehicle enters a curve the cam switch changes over and relay 10 is maintained energized directly from the supply until the vehicle moves out of the curve.

Abstract: 442,548. Oscillographs. COSSOR, Ltd., A. C., and PUCKLE, O. S., Highbury Grove, London. Aug. 10, 1934, No. 23175. [Class 37] An oscillograph system comprises a cathode ray oscillograph CRO having a screen arranged to be viewed through a transparent window, in combination with calibrating means controlled by a switch K adapted to apply to one of the plates Px1 of the oscillograph a change of deflecting potential which can be accurately determined, so as to indicate on the scale the amount of ray deflection which corresponds to a known change of deflecting potential. In the arrangement shown, the switch K connects the plate to either of two tappings on a potentiometer P1, which can be connected in series with a current measuring device by plugging a milliammeter into a jack J. Working current is supplied from A.C. mains through a switch S, transformer T and rectifying valve V. The potentiometer P1 also serves for supplying negative bias to the Wehnelt cylinder W for controlling the focus, the shaft which operates the slider of P1 for this purpose being also arranged to operate the main switch S, in such a way as to ensure that the spot is modulated completely out before the switch is opened. The modulation is also controlled by a second potentiometer P2 connected across the secondary winding of the transformer T and having a slider connected to the cylinder W through a condenser C. The sweep velocity is controlled by a third potentiometer P3 for varying the potential applied to the coils C1, C2 which produce deflection of the ray in one plane, while the plates Px1 and Px2 deflect it in the other plane. A fourth potentiometer P4 varies the potentials applied to one of the plates for controlling the position of the screen picture. The voltage of which the wave form is to be determined is applied across terminals T1, T2. The deflection plates may be split, as described in Specification 442,513, [Group XL].

Title: Improvement in valve mechanism
IPC: F15B13/04
Filed: 1944-11-27
Abstract: 587,916. Fluid-pressure brakes. BENDIXWESTINGHOUSE AUTOMOTIVE AIR BRAKE CO. Nov. 27, 1944, No. 23652. Convention date, Feb. 17. [Class 103 (i)] [Also in Group XXIX] The flow and exhaust of pressure fluid to a brake cylinder 16 is controlled by self-lapping inlet and exhaust valves 12, 14, respectively, the latter including a graduating spring 22 acted upon by a pedal 29a, and when the latter is depressed, its initial movement actuates an auxiliary valve 38 to put the source of pressure fluid, e.g., a reservoir 32, in communication with inlet valve 12, the latter being held open by the graduating spring when the pedal is in its released position. The pedal carries a cam 50 which, on the initial movement of the pedal, first closes an exhaust valve 44 and then opens the inlet valve 38 against its loading spring 39. Pressure fluid then flows from chamber 34, through chamber 36, passage 42, chamber 5, past valve 12, into chamber 6, and so to the actuator 16. The pressure built up in chamber 6 is communicated through a restricted passage 24 to the underside of a diaphragm 21 which supports the lower end of the graduating spring, the upper end of the latter being acted on by an abutment 25 in contact with the pedal. When the pressure on the underside of the diaphragm overcomes the tension in spring 22, the diaphragm will rise sufficiently to allow spring 13 to close valve 12. When the pedal is released, the diaphragm will rise and open exhaust valve 14 so that the pressure fluid in the actuator can flow along passage 53, past a non-return valve 55, past exhaust valve 40 which will have been released by the cam and opened by the exhaust fluid pressure, through ports 46, and so to atmosphere at 47. Auxiliary valve 40 ensures a complete exhaust of pressure fluid from the actuator when the pedal is released. Non-return valve 55 prevents the entering pressure fluid in chamber 36 from flowing to chamber 6 through passage 53. A stop 28 limits the downward movement of the diaphragm. The apparatus is adjusted initially by means of shims 56, 57. A screw 52 engaging a keyway 51 in the exhaust valve plunger keeps the follower 49 in engagement with the cam 50.
