Title: Lamp control circuit
IPC: G05B19/12
Filed: 1956-12-03
Abstract: 850,588. Switching control for incandescent lamps. NIELSEN CO. Ltd., A. C. Dec. 3, 1956 [Dec. 22, 1955], No. 36895/56. Class 38 (4). An apparatus comprising a light-sensitive member such as a film has the member subjected to the light radiated from an electric lamp, the current flowing through the lamp being alternately switched from a value which is insufficient to cause the lamp radiation to affect the light-sensitive member to a value which causes the lamp to radiate to affect the member. A blue-violet sensitive photographic film 23 on which it is desired to record a succession of discrete marks is subjected to the light radiated from an incandescent lamp 21. The lamp 21 is supplied from an alternating current source 18, 19 by way of a voltage regulator 16 and the primary winding 13 of a transformer 12. An adjustable resistor 32 is provided to adjust the current flowing in the lamp-when a thyratron 25 is non-conductive-to a low value so that the filament of the lamp 21 is only warmed to a degree whereby the light emitted from the lamp is mainly in the " red " sector of the spectrum and consequently does not expose the film 23. When it is desired to expose the film a suitable voltage is fed from the source 43 to the controlgrid 25a of the thyratron 25 whereby to render it conducting such that the impedance of the secondary winding 14 of the transformer 12 is reduced. The secondary impedance reflected in the primary side of the transformer is therefore reduced so that a larger current flows through the lamp 21 so that the light emitted therefrom will expose the film 23. Thus the life of the lamp 21 is lengthened as against continual switching ON and OFF. In other embodiments conduction of the thyratron may be arranged to affect the saturation of a saturable reaction; may be arranged to superimpose a voltage on an existing voltage or may be arranged to operate a relay whereby the energization of the lamp is varied. Specifications 819,524 and 823,361 are referred to.

Title: Continuous casting methods and apparatus
IPC: B22D11/04
Filed: 1971-08-10
Abstract: 1333154 Continuous casting I ROSSI 10 Aug 1971 [1 Feb 1971] 37548/71 Heading B3F To avoid bulging and cracking of the shell and to obviate the use of rolls bearing against the side faces, a slab is continuously cast to have concave sidewalls 96, 97, Fig. 5, and is  guided away from the mould by contact at the end walls (as by rolls 76, 77, some of which may be driven and act as brakes) so that the sidewalls 96, 97 are buttressed whilst being cooled. There may be at least two arches at each face with the junctions supported by grooved rolls. By applying pressure to the end walls of the slab by means of rolls as it leaves the mould, the slab width may be reduced and the face concavity increased to break the casting away from the walls of the copper mould. The roller apron bends the casting, if straight, through the arc of a circle, ellipse or parabola or continues the curvature if the mould is curved (in each case one end wall of the casting is on the inside of the curve and the other at the outside) until the casting reaches a withdrawal/straightening unit at a temperature of 1095-1205‹C for steel poured at 1540-1595‹C. By increasing the spacing between rolls of successive pairs, the slab casting width may be allowed to increase progressively to a desired value. To adjust for slab thickness, the flanged ends of the rolls may be slidably mounted on a shaft.  The withdrawal/straightening unit is designed to be capable of straightening the slab cold but also has small antibulging rolls between the heavy straightening rolls 157-160, Fig. 4, for when the slab is delivered so hot that it straightens itself. The upper series of rolls may be staggered in relation to the lower rolls. Bulging of the slab is controlled by automatic regulation of cooling sprays 114, 115, Fig. 5, by a valve 119 operated by an arm 121 carrying a wheel bearing against a slab face. A starter dummy 172, Fig. 9, consists of two curved halves joined side-by-side by a hinge 175 so that it can be collapsed for insertion, by means of ring bolts 185, 185A, between the uppermost rolls 170, 171 of the guide apron which rolls are then driven to insert a shaped end of the dummy into the mould.

Abstract: 326,567. Carpmael, A., (I. G. Farbenindustrie Akt.-Ges.). Dec. 20, 1928. Proofing against vermin; proofing-compositions. -Materials such as wool, fur and hair are protected from textile pests such as moth by incorporating therewith a thiourea of the formula in which R signities an alkyl, alkylene, cycloalkyl, aralkyl, or an aryl residue, and R1 an acid residue. The substituent R may be for example allyl, cyclohexyl, benzyl, phenyl, tolyl, methoxy-phenyl, chloro-tolyl, or trichlorophenyl. and the. acid residue R1 that. of acetic, valeric, stearic, oleic or benzoic acid, or of substitution products of these acids, such as dichlorobenzoic acid, phenylacetic acid, p-chlorophenoxyacetic acid, hexahydrobenzoic acid, &c. Thioureas containing one amino group substituted by an alkyl, aryl &c. residue are produced in the usual manner, for example by the interaction of an aryl mustard oil with ammonia, or the interaction of primary bases with thiocyanate, or, particularly in the production of aliphatic compounds, the interaction of the dithiocarbamine acid salts with mercuric chloride. The mono-substituted ureas thus obtained are dissolved in a solvent such as pyridine or dimethylaniline and treated with an acid chloride, for example, caproic acid chloride or valeric acid chloride. After conversion, the mass is acetylated with hydrochloric acid while cooling, and the separated mixed substituted thiourea is filtered and recrystallized from an organic solvent such as alcohol The substituted thioureas obtained are dissolved in alcohols, benzene, benzine, cyclohexanone, carbon tetrachloride and other organic solvents or mixtures thereof. The strength of the solution used is such that about 1 to 2 per cent of the active substance remains on the fibre. In one example, the material to be protected is treated with a solution of phenyl valeryl thiourea in such a manner that after drying 1 to 2 per cent of the substance remains. Oleyl, benzoyl, dichlorobenzoyl and similar derivatives may be used in place of the valeryl compound. In a second example the material is treated with a solution of phenylcapronyl-thiourea in such strength that after centrifuging and drying 1 per cent of the substance remains on the material.
