Title: Sound-tracks and photographic method of making
IPC: G11B7/00
Filed: 1945-12-10
Abstract: 604,256. Photographic sound films. TECHNICOLOR MOTION PICTURE CORPORATION. Dec. 10, 1945, No. 33327. Convention date, May 17. [Class 98 (ii)] A sound track is printed on a water-absorptive film sensitized with ferric salts, preferably in the sound track zone only, and is developed with a soluble iron cyanide developer to form an opaque insoluble iron cyanide, the film being washed to remove undeveloped iron salts. Specific sensitizers, using acidified ferric oxalate and ferric ammonium oxalate are described, and after printing, development may be effected by ferrocyanide, which causes reversal, or by ferricyanide, and in the latter case the developer may be included in the light sensitive layer and development effected by wetting. Alternatively, a sound track dye image may be formed on the film by dye transfer from a matrix, and then a latent image formed by light exposure through this dye image, preferably with sensitization after the dye transfer step, and subsequent development to produce the final sound track. In this case the matrix may, or may not, be removed before light exposure. In imbibition printing of pictures the sound track may be printed along with the picture, for example in yellow colour, the sound track zone sensitized after removal of the matrix, printing effected with ultra-violet light, and development in the same water bath as required for the imbibition process. An apparatus described shows; in Fig. 1, the film F sensitized at D, joined at rollers 6 with matrix M and exposed under light 17 while travelling round orbital path 1 ; after removal of the matrix at 18 the film is developed in tank 24, washed in tank 26 and dried at 29. The film may then be joined with a second matrix M<1> for another picture colour.

Title: Control device for mechanical movements
IPC: G04F3/02
Filed: 1953-12-01
Abstract: 777,429. Valves. WANTZ, C. Dec. 1, 1953 [Dec. 2, 1952], No. 33370/53. Class 135. [Also in Group XXIV] In a time-controlled valve in which a knob 56 is depressed to open the valve 32 and is then turned to the required time setting, thereby winding up the spiral spring of an escapement mechanism, the knob 56 is locked in the depressed position against the action of the valve spring 42 by a, nearly-reversible screw-thread engagement 58. The stem of valve 32 is received in a recess in the end of the knob shaft 54. Two half-turns of a double thread 58, Fig. 4, are formed on the shaft 54 and are cut off to fit a rectangular recess 74 in a nut assembly 64, the spring 42 normally holding the thread 58 in the recess 74. In this position the shaft 54 is held against rotation by the side walls of the recess. The shaft 54 is connected for rotation with a coaxial pinion 106 loose on the valve stem by a pair of leaf-springs allowing axial movement therebetween. The escapement mechanism 86 is geared to a wheel 100, a flange on which frictionally grips a cup-shaped element on a gear 96 meshing with the pinion 106, and a spiral spring having its inner end fixed is housed in the cup-shaped element so that when the pinion 106 is rotated by the knob 56 the spring is wound up, the frictional connection 100-96 slipping to avoid disturbance of the escapement mechanism. To open the valve therefore, a knob 50 is turned to the position shown to open a plug valve 20 and the knob 56 is depressed to engage the threads 58 with the nut 64 and is turned to an indicated time setting, the turning movement winding up the spiral spring. When the knob 56 is released the threads 58 hold it depressed, i.e. hold the valve 32 open, until the escapement-controlled spiral spring has rotated the shaft 54 sufficiently to disengage the threads 58, whereupon the spring 42 finally closes the valve 32. To hold the valve 32 open independently of the timing mechanism, the knob 56 is depressed and turned slightly in an unscrewing direction to wedge the threads 58 beneath the side walls of the recess 74. Modifications of the screw and nut arrangement shown are described in which the valve is axially moved: (1) by a screw held against rotation by a pin engaging a slot therein, an axially-restrained nut being the rotary control member; (2) by a nut rotated on a fixed screw; and (3) by a nut held against rotation by a guide rod and translated by rotation of an axially-held screw. In each case the tangent of the helix angle equals the coefficient of friction. Specification 777,430 is referred to.

Title: Treatment of nuclear fuels
IPC: G21C19/48
Filed: 1965-08-04
Abstract: 1,115,920. Processing nuclear fuel. GESELLSCHAFT FUER KERNFORSCHUNG m.b.H. 4 Aug., 1965 [8 Aug., 1964 (3); 31 Dec., 1964], No. 33409/65. Addition to 1,037,952. Heading G6R. A method of separating nuclear fuels or of reprocessing irradiated fuel comprises reacting the fuel with a fused salt melt which is maintained at a predetermined pH, the undissolved portion being separated and treated with dilute acid which dissolves the fuel and leaves a residue containing fission products, if present. The preferred melt is alkaline and oxidizing and may contain a metal nitrate; to counteract increased alkalinity due to decomposition of the nitrate, an oxide of nitrogen is introduced into the melt. The melt should be alkaline for the separation of cerium and neutral for the separation of zirco. nium. Fission product iodine is converted to iodate which may be leached out from the melt with water. Fission product strontium and barium are dissolved if the melt contains an alkaline earth salt, e.g. magnesium nitrate, to which may be added lithium, sodium, or potassium nitrate to vary the solidification temperature. The undissolved portion may be separated from the melt by using a centrifuge, by direct filtration, or by solidifying the melt and leaching with water or an alkaline solution.

Title: Arrangement for keeping under observation the loading in alternatingcurrent conductors
IPC: G01R19/18
Filed: 1932-11-25
Abstract: 411,116. Resistance measurements. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin, Nov. 25, 1932, No. 33449. Convention date, Nov. 25, 1931. [Class 37.] An arrangement for keeping under observation the loading in an A.C. conductor comprises a measuring instrument 4 connected with an externally controlled synchronous switch 5, the connections being such that the instrument indicates the ohmic component of the potential drop in the conductor, from which the temperature of the conductor can be ascertained. In the arrangement shown in Fig. 1, the exciting coil 6 of the synchronous switch 5 is connected to the secondary winding of a current transformer 7 in series with the conductor under observation (in this case the primary winding 2 of a transformer), while the instrument 4 is connected as a voltmeter across the conductor. In a modification, Fig. 2, the coil 6 is excited from the secondary winding 3 of the transformer under observation, and the potential drop produced by the operating current in the cold conductor is compensated by an oppositely directed potential obtained from a resistance 8 connected to a current transformer 9, so that the instrument 4 indicates variations in resistance due to heating in the winding 2. In a modification, Fig. 3 (not shown), a crosscoil measuring instrument is used, both coils being fed through the same synchronous switch. In another modification, Fig. 5, potential transformers 15, 16 are connected in opposition through the measuring branch of a cross-coil instrument 4, the controlling branch of which is energized from a shunt connected to a current transformer 18. In this arrangement, the exciting soil 6 of the synchronous switch 5 is energized from a current transformer 17 on the secondary side of the transformer 12 under observation. This arrangement measures the difference between the ohmic components of the potential drops on the primary and secondary sides of the transformer 12. Losses in the transformer core may be compensated by employing an auxiliary coil on the measuring instrument, or by arranging a temperature-dependent resistance in parallel with the two branches of the measuring instrument. The arrangements according to the invention may be employed for the indication of short-circuits and other faults as well as for the observation of temperature. The Specification as open to inspection under Sect. 91 comprises also arrangements for the observation of temperature or resistance in conductors traversed by A.C. and having a purely ohmic potential drop, in which case the externally-controlled synchronous switch may be replaced by a copper oxide rectifier. The manufacture of graphite is instanced as an example of the applicability of such arrangements. The application of the invention to the testing of iron cores is also described. This subject-matter does not appear in the Specification as accepted.
