Title: Improvements relating to Directional Sensitive Apparatus.
Inventor: LUGG SIDNEY
IPC: G01S3/805
Filed: 1966-09-21
Abstract: 1,184,559. Direction-finding; transistor pulse circuits. VACUUM REFLEX Ltd. 19 Sept., 1967 [21 Sept., 1966; 15 Oct., 1966], No. 42121/66 and 46206/66. Headings H3T and H4D. Apparatus for determining the direction of a radiant energy source comprises two spaced receiving transducers and a circuit for providing one of two indications according to which transducer is the first to receive the energy. In the embodiment shown, for locating a pulsed or continuous-wave sound source under water, piezoelectric transducers 10, 12 are coupled to respective signal channels each comprising limit. ing diodes D 1 , D 2 , impedance-matching stage Q 1 , integrated circuit amplifier 14 or 18, monostable circuit 16 or 20 (comprising two NAND gates and a timing capacitor C9) and lamp driver stages Q 3 , Q 4 . The reception of an acoustic signal by either transducer causes triggering of the associated monostable and energization of the corresponding lamp 26 or 28, the two monostables being cross-coupled by lines 32, 34 such that the triggering of either prevents triggering of the other by the later reception of the same acoustic signal by the other transducer. Further transducers coupled in pairs in turn to the two signal channels may be arranged on the circumference of a circle so that the apparatus is direction-sensitive whatever its orientation with respect to the sound source. Audible indicators may be used instead of, or as well as, the lamps, and the monostable outputs may be arranged to operate a servo-mechanism for training the apparatus in the direction of the sound source or for steering a vehicle carrying the apparatus. Instead of the piezoelectric transducers the apparatus may be provided with two spaced aerials or aerial arrays for finding the direction of a radio wave source.

Title: Improvements in processes for the production of fuel in powdered form
IPC: C10L5/00
Filed: 1963-11-28
Abstract: A powdered carbonaceous fuel is obtained by mixing coal dusts of differing ash and volatile content such that the mixture of dusts has 8-12% volatile content, is constituted at least 60% by dust of less than 60 m  grain size, and has an ash content of at least 8%, preferably 15%.  The dusts may be dried to a maximum moisture content of 0.6% whereby they acquire desirable hygroscopic properties.  A minimum quantity of incombustible hygroscopic constituents in the dust of 8% is preferred, additional hygroscopic material being added to dust deficient in this respect.  Dried slurries of identical granularity, ash and volatile content as the dust may be added to the dust mixture. The process may exploit coal of different ash and volatile constituent content found in different seams of the same mine.  In a preferred embodiment, anthracitic coal dusts are used which contain a maximum of 10% volatile constituents; they are ground to <40 m  and dehydrated to 0.6% water content.  A particularly preferred coal is anthracitic and has a >20% ash content of which at least 2/3 rds is constituted by clay.

[Also in Division H2] A circuit in which semi-conductor switches 2 4 alternately conduct to cause current to flow into and out of a series resonant, network 8 (such as an antenna) which tends to continue to oscillate when the drive to the switches is removed, has undirectional conductors 22, 24 connected in series with the switches in such polarity as to block the discharge of the interelectrode capacitance when the drive is removed. It is explained that this discharge current would otherwise flow to the base and switch on the semi-conductor switch, thereby continuing the oscillation when switch 14 is opened. The diodes alternatively could be connected to the power supply connections (Fig. 3, not shown) and diodes 16, 18 return oscillation energy in the power supply when the drive is removed. Each single transistor shown may be replaced by a plurality in series or parallel.
