Abstract: 1,086,698. Television; photo-electric ranging. WESTINGHOUSE ELECTRIC CORPORATION. Dec. 13, 1965 [Jan. 11, 1965], No. 52794/65. Headings H4D and H4F. An optical imaging system for viewing objects only within a predetermined acceptance field of view which may be varied, the system thus being relatively insensitive to ambient and backscatter light, comprises transmitter means for scanning the field of view with a flying spot of light, visible or invisible, and receiver means e.g. an image dissector tube, including a photosensitive surface responsive to the light reflected back from the field of view and an apertured member across which the electron image formed by the photosensitive surface is scanned in synchronism with the flying spot of light so that the receiver responds selectively to the spot or an object illuminated by the transmitter and substantially to no other light. Behind the aperture in the image dissector tube there may be located an electron multiplier the electrical signal output of which is fed to a television monitor for example. The system may be used to determine the range of the objects or targets and also the distance between targets if the beam divergence and size of the aperture projection are considered. The flying spot may be produced by a cathode-ray tube having a phosphor of short persistence time or by a fixed light source and a rotating mirror. The relative angular positioning between the transmitter and receiver may be adjusted physically or electronically (e.g. by moving the raster on the face of the cathode-ray tube) to correspond to the time for light to make the round trip from the transmitter to the object back to the receiver. Thus although the receiver scan is synchronized with the transmitter scan a time lag must be introduced to allow for the light to make the round trip and this lag may be adjusted to accommodate different ranges. Thus the system allows determination of the range of an object, by the lag necessary to bring its image into synchronism for appearing on the monitor. A target outside of the acceptance field of view and between it and the transmitter receiver location will show up on the monitor as a shadow. The acceptance area may alternatively be moved relative to the transmitter receiver location by a relative electrical movement of the aperture projection on the electron image in the image dissector tube using a time delay means to delay the scanning of the electron image in the receiver.

Abstract: 1,188,679. Photo-electric microphone. CESKOSLOVENSKA AKADEMIE VED. 22 Nov., 1967 [22 Nov., 1966], No. 53092/67. Heading H4J. [Also in Division G1] A photo-electric microphone comprises two mirrors, at least one of which is concave, and a light source and a photo-electric detector mounted between them, at least one of the mirrors acting as a diaphragm responsive to acoustic vibrations. In one arrangement, Fig. 1 (not shown), one mirror is plane and the other concave, the light source and detector being located side by side at the focal point of the latter. The plane mirror is inclined at a slight angle with respect to the normal to the axis of the concave mirror, which is attached at its circumference through corrugations to a support, so that it can act as a diaphragm. In the arrangement of Fig. 2, the light source 8 is at the focal point of one concave mirror 6 and the detector 9 at the focal point of the other concave mirror 7. The mirrors hermetically seal the ends of a cavity 10, the pressure inside which can be varied by piston 12 to change the sensitivity of the microphone. Perforated end caps protect the mirrors 6, 7 which are of thin resilient foil and vibrate in response to acoustic vibrations. The cavity 10 may be divided by a transparent window 18. To provide a directional microphone one end cap 6 may be imperforated. The source 8 may be an incandescent lamp or electroluminescent device, e.g. a light excessive semi-conductor diode of gallium arsenide or phosphide, which may be pulse operated. The detector may be a photo-resistor, a germanium or silicon photo-diode or photo-transistor, or a gallium arsenide photo-diode. Alternatively, the detector may be formed by a number of photo-transistors, e.g. a Darlington pair. The photo-detector may be a variable capacitance diode, when it forms part of an oscillator circuit, the amplitude or frequency of whose output varies as a result of the mirror vibrations. Tuned amplifier circuitry may be provided to reduce noise when amplifying the microphone output.

Abstract: 1345069 Spray carburetters P GELE B LAPRADE and X LAPRADE 17 Nov 1971 [20 Nov 1970] 53290/71 Heading F1B Constant depression carburetter has a main passage 1b containing a valve 4b and auxiliary passage 1a containing a valve 4a. The auxiliary passage valve 4a is externally controlled by a linkage 6a which is attached to the main passage valve 4b by a lost-motion connection so that the valve 4b is closed as the valve 4a closes. The main passage valve 4b is also connected by a rod 6b to a diaphragm in a capsule 33, which is connected by a pipe 32 to a chamber 2a defined by the main passage valve 4b and an additional valve 7. Depression in the chamber 2a causes the valve 4b to move in the opening direction. The additional valve 7 is connected by a linkage 9, 10 to a fuel control needle 11 which cooperates with a jet 19 mounted in a float-chamber 1c. Fuel passing through jet 19 mixes with air entering through an orifice 22 and the mixture passes along a pipe 20a to the auxiliary passage 1a and down this passage to a Venturi 26. In the auxiliary passage there is also an additional valve 13a mounted on a spindle which also carries a lever 13b; attached to one end of the lever is a spring 29 which is also attached to an adjustable screw 31, and attached to the other end is a spring 28 which is hooked on to a rod 27. This rod is pivotally connected at one end to a lever 8c fixed on the pivot shaft of the additional valve 7 and at its other end is free to slide through a hole in a boss 5e at the end of an arm 5d secured to the shaft 5b which carries the main passage valve 4b. The boss 5e co-operates with a slot in the rod 6c to form a lost motion connection. Mounted on the additional valve 7 is a spring arm 24 which biases a conical valve member 23 into a valve seat formed in the valve 7. Operation. The valves 7 and 12 are mounted offcentre and open as the air-flow increases, the movement of valve 7 being transmitted to needle 11 so that a fuel/air mixture issues from nozzle 20. The main valve 4b is opened by the depression in the chamber between the valves 7 and 4b, through the capsule 33 and is closed by the driver-controlled linkage 6a, 6c. During acceleration the main valve 4b opens more rapidly than the additional valve 7, so that the middle of the rod 27 moves to the right, increases the tension of the spring 28 and tends the close valve 12. Closure of valve 12 increases the depression in the space between valves 12 and 4a and increases the richness of the mixture by drawing fuel and air through nozzle 20. During idling the conical valve member 23 opens to allow additional air to pass through the opening 7a to augment the air entering through the opening 22.
