Title: Improvements in photo-electric detector units for automatic headlamp dimming apparatus
IPC: B60Q1/14
Filed: 1952-10-20
Abstract: 740,160. Photo-electric headlamp dimmer. GENERAL MOTORS CORPORATION. Oct. 20, 1952 [Nov. 10, 1951], No. 26207/52. Class 40 (3). In a photo-electric headlamp dimmer the cell receives light by way of a condensing lens and optical means which tends, by refraction, to equalize the effect of light beams on the cell irrespective of the approach angle of the beams over the angular range of which the detector unit can receive light. As shown, light from the headlamps of an oncoming vehicle is directed on to a refracting member 72 by a stepped lens 14. Behind the refracting member is positioned a photo-electric cell 16. The refracting member, shown in detail in Fig. 5, is generally rectangular in shape and is of glass or transparent plastic. On one face of the rectangle is a prism 100 and on the other a cylindrical lens 88. The ridge 90 of the prism faces lens 14 and is vertically positioned. The cylindrical lens face is coated with an opaque substance except for a window 98 and the top and bottom of the refracting member are also coated, the refracting faces of the prism being clear (Fig. 3). Window 98 is positioned at the focal point of lens 14 adjacent the photo-electric cell 16 which may be of the multiplier type. The effect of the cylindrical lens is to refract light falling on lens 14 within a certain angle above or below the horizontal plane on to the cathode of the photocell and the prism acts similarly for angles each side of the central plane. The refracting member is of light-filtering material such as ambercoloured plate which eliminates blue light. A separate light filter may be employed, or the condensing lens may be of light-filtering material. The refracting member is held in position by a slotted plate 78 and screw 76. The housing is in two parts 22, 24 held together by screws 28 and is mounted behind the windscreen by a bolt 46. A pivot 42 permits vertical angular adjustments, a spring 48 being provided to hold the housing against a screw 60 which is used to adjust the housing angle. In a modification the cylindrical lens is replaced by a prism with its ridge at right angles to that on the front face of the device. Specifications 740,239 and 740,240 are referred to.

Title: Synchronizing arrangements for television transmitting apparatus
IPC: A61K9/20
Filed: 1961-07-21
Abstract: 971,313. Television; automatic phase control systems; pulse modulation circuits. FERNSEH G.m.b.H. July 21, 1961 [July 23, 1960; May 12, 1961], No. 26493/61. Headings H3A, H4F and H4L. From a television transmitting central station a controlling reference signal in two ways differently modulated is sent to mobile or other television cameras to control both their horizontal and vertical synchronization in such a way that horizontal sync. pulses received back at the central station from the camera units are in phase with a master pulse generator at the central station, irrespective of variable signal transit times between the cameras and central station, as during cross fading. The reference signal may be a carrier, frequency modulated by pulses of duration varying with any lack of coincidence of central station master horizontal pulses and horizontal pulses received from the cameras. Further, the pulse amplitude may be increased each time a central station vertical pulse is produced, i.e. only direct vertical synchronizing at the cameras is used, and the pulses may be time modulated with a supervisory speech signal. At a camera the leading edges of the variable duration pulses, after limiting, are differentiated by capacitors 64, 65 (Fig. 2), to produce from the collector circuits of transistors 62, 63, negative and positive going pulses (C), (D) of variable time spacing. Pulses (C) produce a sawtooth wave (E) at capacitor 77 of a transistor bootstrap sawtooth generator 73, 81, which through emitter follower 81 is applied to a transistor phase detector 84 with other input being pulses (D), to derive a positive or negative D.C. voltage controlling the frequency and phase of horizontal sync. pulse generator 52. (This system produces a faster acting control system than by merely integrating the variable duration pulses). The sawtooth wave E, and horizontal sync. pulses L generated at the camera, are also applied to a pulse time (phase) demodulator 93 whose output (M) is a staircase wave which through an amplifier 95 reproduces any speech signal. Output (M) varies in amplitude depending on the peak amplitude of the sawtooth wave (E), i.e. on the frequency difference between the generator 52 of pulses (L) and the incoming reference pulses, of recurrence frequency equal to that of (E), so that during out-of-synchronism the rectified peak voltage of wave (M) across capacitor 101 cuts off a normally conductive transistor 89 and decreases the time constant of the smoothing circuit preceding oscillator 52, to increase the pull-in range.

Abstract: 362,931. Rectifying alternating current. AKT.-GES. BROWN, BOVERI, ET CIE, Baden, Switzerland. Sept. 5, 1930, No. 26520. Convention date, Sept. 9, 1929. [Class 38 (ii).] In an arrangement for preventing back ignitions in a multi-anode mercury arc rectifier G by means of grids energized by a star-connected winding 52, the neutral point of the latter is maintained at a potential lower than the cathode and equal to or higher than the star point of the main winding S1 feeding the anodes. Fig. 1 shows an arrangement in which the star point of the grid winding is maintained at a potential between that of the cathode and the star point of the anode winding by connection to a potentiometer R. Fig. 2 shows an alternative arrangement in which the two star points are interconnected, the grid windings being modified by phase combination to give the grid potentials such lead with respect to the anode potentials that each grid is rendered negative before the corresponding anode ceases to conduct. In a further arrangement, Fig. 3 (not shown), the grid windings are arranged on the same core as, and combined with, the anode windings. A small auxiliary generator, driven for example by the vacuum pump motor may be used to supply grid potentials instead of the transformer. Alternatively, a synchronous converter may be used for supplying grid potentials, the same machine, when excited with the load current of the rectifier, serving for power factor correction.

Abstract: 931,991. Retractive switches. NATIONAL ACME CO. Aug. 3, 1960 [Aug. 13, 1959], No. 26899/60. Class 38 (5). In a snap-action limit switch the operating machine member rotates lever 42 and hence coupled clutch members 17, 18 clockwise to bring an operating cam 20 into the position shown. The cam-follower 108 thus moves slider 101 to the left, detent 103 striking a shoulder 93 on a latched plate 90 to compress the snap spring 105. A release stud 109 on the slider 101 then reaches the position shown in Fig. 6, where it trips spring-loaded latches 118 to release lugs 93 and allow the spring 105 to snap the slider 101 to the left. This carries with it the contactcarrier 81 so that spring-loaded contacts 83, 84 leave a contact pair 66 and engage a similar pair 65 with a snap-action. Upon release of the operating lever 42, cam-spring 36 returns the cam 20 to normal and return spring 107 urges the slider 101 to the right. The contacts 83, 84 thus snap back under the control of bell-crank latches 119. In order that the switch may be operated instead by a counterclockwise movement of the lever 42 and cam 20, the cam member 17 may be withdrawn manually from its drive member 18 and rotated through 90 degrees. The contacts are separated from the operating mechanism by a slotted partition 14 and the switch is closed by cover-plates 12, 13 and gaskets (not shown). The contacts may be replaced by butting contacts 140, 142 (Fig. 9) and in this case additional shoulders on the latches 118 may provide a central OFF position. Specification 912,223 is referred to.
