Title: Range finder including photo electric devices
IPC: G01S17/46
Filed: 1972-03-30
Abstract: 1392198 Photo-electric distance measuring EASTMAN KODAK CO 30 March 1972 [12 April 1971] 15099/72 Heading H4D A range finder for indicating in which of two zones an object is located comprises means for projecting a light beam and two photosensitive devices producing a signal, the magnitude and polarity of which provide the required indication. A light beam 43 modulated by chopper 44 is reflected from objects in zones 1, 2 on to cells 51, 52. If the object is in the crossover region the cells receive substantially equal illumination and provide a signal of low amplitude at the output of differential amplifier 57. This is filtered by unit 60 but being of lower amplitude does not produce a signal at the output of unit 64. If the object is in either zone 1 or 2 however a signal of corresponding polarity is produced by amplifier 57, the cells being unequally illuminated. The resulting signal from unit 64 is passed to AND gates 66, 68, and the corresponding AND gate enabled by a signal from units 70, 72. If the object is in zone 1 gate 66 is enabled and if in zone 2, gate 68 is enabled. Consequently coils 82, 84 are selectively energized to move lens 14 back or forth and produce a focused image on film plane P. In alternative embodiments (Figs. 2, 3, not shown) either lamps produce images in a camera viewfinder (90) indicating the zones and lens 14 is adjusted manually or a further object lens (14<SP>1</SP>) is swung in or out of the line of object lens 14, according to the zone, in order to focus the image.

Title: Boron carbide spherules
Inventor: SOWMAN HAROLD G
IPC: C04B35/56
Filed: 1961-07-21
Abstract: Crystalline carbide spherules of boron carbide of diameter 10m  to 125 mils. are prepared by heating discrete irregular particles of this carbide uniformly dispersed throughout a finely divided inert solid isolating medium in a non-reactive atmosphere to above the melting point of the carbide but below that of the isolating medium to form spheres by the effect of the surface tension of the molten carbide.  In a modification of the process, the carbide particles are replaced with irregular particles of boron or the oxide thereof, and the isolating medium is carbon or contains sufficient carbon to produce the carbide on heating.  The preferred isolating media are boron nitride and carbon, e.g. graphite, carbon black, lampblack, amorphous carbon, or petroleum coke, and the particle size of the medium is at least one order of magnitude smaller than the material to be converted into spherules.  The proportion of isolating material to carbide or carbide precursor can be varied over a wide range, and the non-reactive atmosphere may be helium or argon and the temperature 2300 DEG  to 2700 DEG  C.  The spherules are cooled rapidly, e.g. by removal from the furnace, whilst maintaining the non-reactive atmosphere. The process may be carried out in a furnace or on a refractory pallet or on a bigger scale using a rotary kiln. Carbon may be removed from the surface of the spheres produced by treatment with a detergent or alternatively by oxidation under controlled conditions, e.g. by refluxing with chromic acid solution, or by heating in air to 1000 DEG  C. Ultrasonic vibrations may also be utilized for cleaning the spherules.  The spherules are used in atomic reactors as control elements, being dispersed in a metallic matrix.

Abstract: 1429303 Automatic control of speed CAV Ltd 21 March 1973 [4 April 1972 (2)] 15347/72 and 15348/72 Heading G3R  In a system for controlling the fuel supply of an I.C. engine the output of a transducer measuring an engine operating parameter is passed through a circuit which is responsive to a fault condition to cause the control system to reduce or cut off the fuel supply. In the embodiment shown the pump position transducer 53 comprises a variable coupling transformer whose output is rectified at 55 and passes to an amplifier 57. The output of the amplifier is connected through resistors 16a, 16b into the main control circuit which is similar to those disclosed in Specifications 1416861 and 1416862. The transducer provides a high output when the fuel supply is zero and thus provides an output from amplifier 57 which is low under fault conditions. The normally non-conductive transistor 62 responds to an excessively high output of amplifier 57 under other fault conditions to operate safety circuit 65 which disables the control amplifier 25 to de-energize actuator 13 and allow the spring-biased pump control rod 14 to return to a minimum fuel condition.
