Filed: 1971-06-09
Abstract: 1319716 Automatic train control SOC TECHNIQUE POUR L'INDUSTRIE NOUVELLE SA 9 June 1971 [17 June 1970] 19617/71 Heading B7N Train control signals for vehicle 180 are applied via track circuit 160 and pick up coils 181 from switching circuits 12, 13 which act to modulate the phase of the A.C. signal on line 11 under the control of the train control signals from unit 15. Positive control signals have no effect on the phase of the A.C. voltage, but negative control signals reverse the phase of the voltage for their duration, the switching occurring as the voltage passes through its zero value. On the vehicle the received signal is applied to two channels, in the first of which it is rectified to produce a signal at twice the frequency of the A.C. signal which is then divided by two to reproduce the original A.C. signal. This latter signal is then compared in a phase comparator with the received signal in the second channel to reproduce the train control signal.

Filed: 1925-08-07
Abstract: 259,341. Cubitt, A. S. Aug. 7, 1925. Stercoscope systems; relief effects in kinematograph images, producing. -In order to obtain an effect of relief in a photograph, a camera having a lens of large aperture is used, and a diaphragm having a small aperture is moved either across the lens from one side to the other, or in a circular path round the centre of the lens. In the production of kinematograph pictures, the moving diaphragm is geared with a shutter so that alternate pictures are taken when the diaphragm is moving on opposite sides of the centre of the lens. In the form shown in Fig. 11 for still photography, a diaphragm 5 having an aperture 2 is geared at 6, 7 with a rotary shutter 4 having an exposure opening 3, so that, on release of the shutter trigger 10, the aperture 2 passes approximately horizontally across the lens 1 when this is uncovered by the exposure opening. This form may be modified for kinematography by arranging the gearing between the diaphragm and the shutter so that during alternate exposures the aperture 2 moves respectively over the right and left halves of the lens 1. In the form shown in Fig. 13 for kinematography, the shutter 4 carries a pinion 7 gearing with teeth on the periphery of the diaphragm 6 so that the aperture 2 therein describes a circular path round the centre of the lens 1 as the shutter rotates. At each exposure the aperture 2 describes an angle of 45‹ about the centre of the lens, alternate exposures being made on opposite sides thereof. A modification is also described for still photography in which the diaphragm aperture describes a complete circle round the centre of the lens during exposure.

Abstract: 1,060,879. Hall effect devices. BECKMAN INSTRUMENTS Inc. May 12, 1965 [June 9, 1964], No. 19972/65. Heading H1K. In a Hall effect device comprising a layer of semi-conductor material on one face of a thin insulating substrate at least one of the control current or output leads consists of a conductive lining in an aperture extending through the substrate and in a channel extending in the opposite face from the aperture to the edge of the substrate. In a typical device, Fig. 6, the channelled and apertured substrate 70 of alumina, beryllia or steatite is formed by moulding. The channels and apertures are metallized with molybdenum-manganese or platinum-gold, which after firing is reinforced by plating with gold or silver. A thin cruciform layer of indium arsenide or antimonide is then vapour deposited on the unchannelled side of the substrate. To facilitate welding on of conductors the channels are of increased depth at the edge of the substrate. An alternative arrangement (Fig. 9, not shown) is similar except that the slots 51, 54 accommodating the control-current tracks are replaced by cut-outs in the substrate edges and the arcuate section 35 of the second output conductor is replaced by a section in line with the first output conductor. Devices of the above type exhibit reduced and predictable error voltages.
