Title: Colour photographic process
IPC: G03C7/18
Filed: 1949-02-23
Abstract: 685,608. Colour photography. GANGUIN, K. O., and IMPERIAL CHEMICAL INDUS. TRIES, Ltd. Feb. 23, 1950 [Feb. 23, 1949],- No. 4914/49. Drawings to Specification. Class 98 (ii). A duplicate colour photographic record from which copies may be taken, designed to avoid repeated printing operations from a valuable original negative while minimizing progressive deteriation in colour fidelity, is made by exposing a true-colour colour-former multilayer film to light transmitted by an original false-colour colour record and processing by reversal. Preferably, the false-colour record used is made from a multilayer film having sensitivity-colour former combinations of blue-yellow, green-cyan and red-magenta; but any combination, as set out in a table showing all alternatives provided that the blue-sensitive layer is uppermost, may be used. The false-colour record used may be that of Specifications 685,607, 685,610, and 685,612, carrying respectively black and white, azo- and styryl-dyestuff colour correcting masks. An example repeats that of 685,607 but concludes by describing production of the duplicate colour record instead of running on directly to production of a positive from the camera film; and states that a positive made from such duplicate has much improved colour fidelity and saturation as compared with a positive resulting from true colour duplicate or master record procedure. Specifications 486,848 and 489,162 also are referred to.

Title: Arrangement in electric differential protection devices
IPC: H02H7/045
Filed: 1942-04-16
Abstract: 554,210. Protective cut-out systems. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. April 16, 1942, No. 5044. Convention date, May 5, 1941. [Class 38 (v)] A differential protective arrangement, particularly applicable to transformers having two or more windings, and immune from operation by current - transformer saturation on heavy through-faults, comprises a blocking relay with its contacts in series with those of the differential relay itself, and the balance type, one member actuated by the sum of the currents to the protected section and the other by the difference of such currents. The blocking relay is preferably arranged to open its contacts when normal full-load current is exceeded and provided no appreciable difference-current flows, but will close its contacts if there is an appreciable difference-current, so permitting the differential relay to operate. In a simple two-winding transformer, Fig. 2 (not shown), a beam relay 8 with spring 12, Fig. 3, is acted upon in the closing direction by a coil 10 carrying the normal difference current, and, in opposition, by a coil 11 normally carrying the sum of the currents entering and leaving the transformer 1. Thus, on through faults, the relay is held open notwithstanding there may be appreciable difference-current, but on internal fault the restraint disappears. In a three winding transformer application, Fig. 3, the restraint is provided by windings 11 carrying the currents x, y, z in the several lines to the transformer 1, and the winding 10 carries the difference-current and is in series with the winding 15 of the differential relay, the contacts 16 of which are in series with contacts 9 in the trip circuit. In Fig. 4, one set of restraining windings carries the currents x, y in opposition, whereas the other set carries currents z in opposition to x+y. The mathematical theory underlying the invention is given in the Specification, together with graphs. Fig. 5 (not shown).

Abstract: 621,369. Arranging small articles. VICARS, Ltd., T. & T., and FLETCHER, W. P. Feb. 24, 1947, No. 5267. [Class 117] A machine for accepting small articles such as biscuits 1 irregularly dropped on a conveyer belt and separating them into rows comprises an inclined plane 4 down which they slide by gravity, provided with parallelly disposed upstanding ribs 5, 6 inclined first in one direction transverse to the inclinations of plane 4 and then in the opposite direction. The ribs are spaced apart at a distance slightly greater than the dimension parallel to the minor axis of the plane of the articles and at a height such that the hypotenuse from the base of one rib to the top of the next adjacent rib is less than the dimension parallel to the major axis but greater than the dimension parallel to the minor axis so as to cause the articles to turn with either of those axes in the direction of travel. On reaching the bottom of the inclined plane 4 the articles are positively conveyed by a moving upwardly-inclined belt 3 between spaced guide fins 8 contiguous to the ends of the ribs 5, 6 which may embrace the fins 8. These latter may be adjusted in height above the belt 3 by mounting them on block 10 displaceable laterally in guides 11 by nut and screw gear 12. The conveyer 3 delivers the articles with the larger axis in. the direction of travel to an inclined chute, at the end of which is disposed a star wheel which deflects the articles through the vertical to present them on their edges to a slowly-moving belt conveyer to displace them in juxta-position progressively away from the chute.

Patent GB-810450-A (GB)
Title: Process for the manufacture of lubricating oil additives
Inventor: SHELLARD ARTHUR DONALD
IPC: C10G27/12
Filed: 1957-02-19
Abstract: A lubricating oil additive is prepared by treating with an organic peracid an aromatic extract from a mineral oil.  Peracids referred to are the peracids of the fatty acids such as performic, peracetic, perpropionic and perbutyric acids, of substituted fatty acids such as monochlorperacetic acid and trichlor-peracetic acid, and of aromatic carboxylic acids such as perbenzoic acids. The peracids may be used as such or may be formed by treating the extract with a mixture of the organic acid and hydrogen peroxide. The aromatic extract may be prepared by extracting mineral oils with solvents such as liquid SO2, phenol, furfural, nitrobenzene, cresol, aniline and b -b 1-dichlordiethyl ether; mixtures of solvents such as liquid SO2 and benzene, and propane, cresol and phenol may also be used.  The mineral oil may be a lubricating oil, kerosine, gas oil or a cycle oil from a catalytic cracking process.  From 2-25 per cent by weight of the peracid, based on the extract, may be used.  If the aromatic extract is viscous, it may be diluted with, for example, thin lubricating oil, gas oil or kerosine or a solvent such as xylene, toluene or petroleum ether.  After treatment with the peracid, the extract may be washed with water or with an aqueous or alcoholic solution of an alkali, e.g. caustic soda, sodium carbonate or ammonia; traces of water may be removed by azeotropic distillation with a volatile solvent such as benzene, toluene and xylene. Alternatively, after treatment with the peracid, the aqueous phase may be removed and a solid alkaline material, e.g. calcium carbonate or lime, or a mixture of sodium carbonate and an activated earth, added and the mixture filtered.  The extract may be treated with successive batches of peracid.  The additives may be added, for example in a proportion of 0.5-15 per cent by weight, to hydrocarbon lubricating oil, such as a mineral oil derived from a naphthenic, paraffinic or asphaltic crude petroleum; the oil may be a mineral oil refined by such treatments as sulphuric acid or oleum, earth or lime treatment, or solvent extraction.  The compositions may be blended with fatty oils, e.g. rape seed oil and lard oil, and/or with synthetic lubricating oils, e.g. polymerized olefins, aromatic hydrocarbons alkylated with olefins or alkyl halides, organic esters, e.g. dialkyl esters of dicarboxylic acids such as di-(2-ethylhexyl) sebacate or adipate, and alkyl or alkaryl esters of inorganic acids, e.g. trioctyl or tricresyl phosphate and tetraoctyl silicate, polymers or copolymers of polyalkylene glycols and the esters and ethers thereof and polyorganosiloxanes.  Specification 764,183 is referred to.

Title: Improvements in or relating to cooling systems for electronic valve apparatus
Inventor: SIMPSON PETER GRAHAM
IPC: H01J7/24
Filed: 1961-02-15
Abstract: 912,102. Cooling systems for electronic valve apparatus. COMMUNICATIONS PATENTS Ltd. Feb. 15, 1961, No. 5656/61. Class 64 (3). Electronic valve apparatus 17 is cooled by a liquid circulated in a closed system including a water storage tank 10 having a pipe 28 for discharging water to waste under the control of a thermal switch 36 sensitive to the temperature of the tank water and regulating the flow of such water to waste, and means for replenishing the tank from a cold water supply. In the system shown, the circulating coolant is oil which is cooled in passing through a heatexchanger 60 in the tank 10. A resulting rise in the temperature of the tank water above a predetermined value is sensed by the element 36 which then opens the waste pipe valve 21 allowing water to discharge through pipe 28. The consequent fall in the water level A operates a switch 33 which opens a cold water inlet valve 12 until the level is restored. In a further form described (Fig. 1, not shown), the circulating liquid is water and the storage tank 10 is connected directly into the cooling system, the heat-exchanger 60 and make-up tank 61 then being omitted. The system may also incorporate an air-cooled cooler 30.
