Abstract: 1,003,437. Moving coil meters. EASTMAN KODAK CO. Sept. 24,1963 [Sept.26, 1962], No. 37477/63. Heading G1Q. In a moving coil meter having a coil 38 mounted for angular movement about a permanent magnet core 10, the coil is mounted for rotation on a pair of supports disposed between the coil and opposite ends of the core, the first support 24 being attached, as by riveting, to a frame 14 which also serves to locate the core 10 and has secured thereto the ends of a U-shaped member 16, in the central portion of which the second support 20 is mounted, capable of axial adjustment as by being screwed into or out of a threaded aperture in said central portion. Supports 20, 24 comprise pivot pins 28, 30 which engage bearings 32, 34 on the inner side of the coil former 36; alternatively, the bearings may be mounted on the frame 14 and member 16, and the pivot pins on the coil former. A spring 22 within member 16 exerts pressure between support 20 and core 10 and urges the latter into a recess 12 in frame 14; alternatively core 10 may be cemented in the recess and spring 22 omitted. A terminal pin 50, insulatedly held in a cylindrical magnetic return member 40, is connected to an external lead 58 and, via spiral spring 42 and anchor member 46 therefor, to coil 38; the return current both is via an anchor member 48 a spiral spring 44 and a zero regulator 26 therefor, to the frame 14 to which is connected a second terminal (not shown).

Abstract: 1,051,906. Photographic cameras; exposure control systems. PENTACON DRESDEN, KAMERAUND KINOWERKE V. E. B. March 11, 1964, No. 10273/64. Heading G2A. A camera has setting members for shutter speed and range which are coupled together and are set through a common setting ring 24 which is coupled with the lever 38 to rotate galvanometer 21 associated with a light sensitive cell 22, the galvanometer pointer 20 controlling the setting member 12 of the lens diaphragm 42, and the ring 24 being optionally couplable with time setting ring 27, through catch 48, 49, for various positions of ring 24. In operation, the shutter is cocked by rotating lever 14 clockwise to carry with it lug 13 of a speed setting member 41, a further lug 16 lifting slider 18 away from pointer 20. Tube 29 is rotated to turn distance setting member 12 and time setting ring 27 by means of the ring 24, thus focusing objective 8 and at the same time setting a corresponding shutter speed through a cam on ring 27. The values are displayed on a subject scale by pointer 34 through cam 32, and the rotation of ring 27 sets the galvanometer through cam 36, rod 39, and lever 38, in accordance with the selected speed. When lever 40 is released, lever 14 of the shutter 15 runs down followed by lug 13 of diaphragm setting member 43 due to spring 17 on slider 18 whose cam 19 finally engages pointer 20. The aperture is then set depending on the galvanometer deflection. If the mark 51 is opposite subject mark 53 when the camera is set, then the correct subjecttime setting exists. This subject-time pairing may be avoided by the release of catch connection 48, 49 and the rotation of catch ring 47 relative to control ring 29. Reference has been directed by the Comptroller to Specification 897, 953.

Abstract: 1289383 Measuring semi-conductor junction reverse leakage current AMERICAN ELECTRONIC LABORATORIES Inc 4 Feb 1970 5268/70 Heading G1U In a method of measuring the reverse leakage current of a semi-conductor junction device while it is connected in a circuit, e.g. the collectorbase reverse current of a PNP junction transistor T, Fig.1, the junction is connected BC across an arm R 2  of a bridge 14, across the vertical diagonal of which is applied both a relatively small A.C. voltage E 1  and a D.C. voltage E 2 chosen to bias the junction to a point, such as 52, Fig.3, on its characteristic where its D.C. resistance is low and its A.C. resistance is high, the bridge is balanced for A.C. by adjusting one of its arms R 1  in accordance with the indication on an A. C. meter M 1 , and then the out-of-balance D.C. current is determined by a meter M 2 , this current being linearly proportional to the current through the semi-conductor junction. In practice, when measuring the collector-base reverse current of a transistor T, Fig.1 the in-circuit emitter-base impedances R 5  are shorted by a conductor 42, so that the circuit is equivalent to that shown in Fig. 2, in which the arm R' 2  is equivalent to the arm R 2  of the bridge 14, Fig. 1 in parallel with the in-circuit collector-base impedance R 7  and the collector-emitter impedance R 6 . Balancing the bridge for A.C. effectively balances the resistors R 1 , R' 2 , R 3 , R 4  in the bridge because the A.C. impedance of the collector-base junction is very high, so that any subsequent out-of-balance D.C. current can be regarded as arising from the transistor acting as a current source, and is clearly proportional to that current, i.e. to the collector-base reverse leakage current. The specification shows this algebraically, and also that if the meter M 2  is calibrated for no in-circuit impedances then typical values of such impedances produce less than a 10% variation in the meter reading.

Preferred compounds which evolve carbon disulphide on treatment with acid are thiocarbamates of formula: in which R 1  and R 2 , which may be the same or different, are an alkyl or aralkyl residue, or R 1  and R 2  together are an alkylene, oxyalkylene or thioalkylene residue to form a monoheterocyclic ring with the nitrogen to which they are attached, and Me is a cation, preferably an alkali metal, alkaline earth metal or nitrogen base cation. The first component of the storage-stable combination may include an inorganic dehydrating salt such as an alkali metal sulphate, silicate or carbonate. The thiocompounds used are stabilised by alkaline-reacting substances to prevent hydrolysis in moist carbon-dioxide-containing air. Suitable stabilisers include carbonates, borates, phosphates, acetates and phenates. Phenates such as sodium trichlorophenate, sodium o-phenyl phenate or sodium pentachlorophenate are particularly suitable, since they are also bactericides A process for killing coccidia eggs and nematodes comprises admixing a dry mixture containing a compound which evolves carbon disulphide in aqueous acid and a non-ionic and/or anionic emulsifier and aqueous acid sufficiently concentrated to provide a carbondisulphide-containing aqueous solution on reaction with the dry mixture, and applying to the coccidia eggs and nematodes the aqueous solution thus produced.

The stack gas may be passed in until the pH is below 3À5 where it is held to prevent formation of a gel. The reaction mixture may after removal of insoluble material be contacted with a reducing gas, e.g. H 2 S. The stack gas may however be passed in so that the dihydrated silicic acid is converted to monohydrated silicic acid then to dehydrated silicic acid when a gel is formed and then more waste gas is passed into the gel. The gel may be dehydrated to a free moisture content of 10 to 20% by weight and heated to recover the SO 2  or contacted with a reducing gas to recover sulphur. The gel may be moistened and then contacted with the reducing gas. The reducing gas may be formed in situ by adding a mineral acid and pyritic material to the reaction mixture either at ambient temperature or with subsequent heating with steam to accelerate the reduction to sulphur.
