Title: Improvements in protein derivatives
Filed: 1953-09-24
Abstract: Protein derivatives are prepared by reacting a cyclic organic imide with a protein in the presence of water at a pH of from 8 to 12.  The reaction is conveniently carried out in aqueous dispersion, e.g. in water, water-acetone, water-dioxane or water-formamide, preferably at 30-50 DEG  C.  Alkali may be added periodically to maintain the pH value constant.  In examples: (1) a dioxane solution of phthalimide is added to an aqueous solution of gelatine, a pH 9.5 and a temperature of 40 DEG  C. being maintained during the reaction; the mass is then chilled and washed, melted, acidified, filtered and dried; (2) succinimide is likewise reacted with gelatin.  The gelatin derivatives may be used in lithographic printing processes and in photographic processes (see Group XX). Other specified proteins are casein, egg albumin and soybean protein.  Specification 649,545 is referred to.

Patent GB-265849-A (GB)
Abstract: 265,849. Mond, A. L., (Metallbank und Metallurgische Ges. Akt.-Ges.). June 30, 1926. Cables and conductors, apparatus and processes for making.-Comprises a method of and apparatus for the manufacture of hollow conductors made from profiled bands so that no internal support or the section of the hollow conductor is necessary. The bands used in the manufacture of the conductors are provided with zig-zag flanges or recesses, projections and grooves by which interlocking is effected. Several examples are described in the Specification, those of Figs. 8, 9, 10 and 14 being typical. In manufacture, the profile of the strip must be altered, so that the grooves are opened and then closed on the tongues and a smooth external surface obtained. The ordinary machines for stranding conductors are modified to adapt them for this purpose. An adjustable mandrel 1 is guided in a nut 2 and may be rotated, the longitudinal adjustment being effected by the hand-wheel 3. The mandrel 1 extends into a guide member 5, formed as a drawing plate for guiding the bands and tapering the conductor to the correct diameter. This guide member may either be stationary or rotary. The wires are passed through guides 8, 9 in the stranding machine, which are rotated, the wires being drawn through under tension applied by the roller 10. Bobbins 7 carry the wires, which after reaching the guiding member are caused to interlock thereby and are pressed into close contact on the mandrel 1. In some cases, the conductors are constructed with a carrier rope n, Fig. 17, arranged in the interior. Specification 247,197 is referred to.
Patent GB-774466-A (GB)
Title: Sterol compounds and the purification thereof
IPC: C07J9/00
Filed: 1955-09-16
Abstract: Stigmasterol and sitosterol are separated from each other in a process which comprises subjecting a solid mixture consisting essentially of stigmasterol and sitosterols to countercurrent selective extraction with a selective organic solvent for the starting mixture, thereby producing a residual solid which contains one of the two starting sterols in greater proportion than in the starting mixture and producing a solution of solids in the spent solvent, which contains the other sterol in greater proportion than in the starting mixture and then separating the liquid phase from the solid phase.  Preferred solvents are ethylene chloride or n-heptane or mixtures thereof.  Also mentioned are methyl isobutyl ketone, isobutyl alcohol, decahydronaphthalene, a -methylcyclohexanol, isopropyl ether, isopropyl acetate, ethyl acetate, n-amyl alcohol, methyl cyclohexane, dioxan, n-butanol, cyclohexane, 2-nitropropane, ethoxyethanol, carbon tetrachloride and acetone.  The counter-current extraction may be continuous, semi-continuous or batchwise.  In the batchwise extraction, each batch of sterol mixture is extracted with at least four successive volumes of organic solvent followed by the separation each time of the undissolved solids.  The mother liquors obtained by extraction of the first batch is stripped of the sterols dissolved therein by precipitation and the sterols so obtained extracted with the following batch.  In the continuous countercurrent extraction a stream of solid mixture consisting essentially of stigmasterol and sitosterols is extracted with a continuous stream of selective organic solvent for the starting mixture, having a relative distribution coefficient greater than one and travelling in a direction countercurrent to the flow of the stream of the said mixture.  The extractions are preferably carried out between 15-45 DEG  C.  Preferred starting sterol mixtures are soysterols and sugar cane wax sterols.  Prior to the extraction treatment the starting soysterols may be cleaned up with chloroform and Skellysolve. Examples describe batchwise extraction with and without stripping stages.

Title: Control system for a coal consuming apparatus
IPC: G05B15/02
Filed: 1976-06-25
Abstract: A plurality of first logic processors are interconnected in a "ring" type network and individually exercise control over similar equipment group subsystems which individually contribute to the operation of an overall system. Each of the interconnected processors, in addition to its primary control function, monitors the safety of operation of the equipment group with which associated and the safety of operation of a "neighboring" equipment group. Redundant safety checks are thus performed on each equipment group and any discrepancies in the results of such safety checks are enunciated. A pair of further logic processors, in addition to performing other control functions including scheduling the operation of the individual equipment groups, redundantly check the safety of operation of the overall system.

Abstract: 761,627. Jettisoning aircraft cockpit hoods. ARMSTRONG WHITWORTH AIRCRAFT Ltd., Sir W. G. July 1, 1955 [Sept. 21, 1954], No. 27239/54. Class 4. An aircraft hood jettisoning system includes at least two jacks 13 placed for jettisoning the hood, each being operable by a detachable explosive having a firing pin, and passages 30 connected to all the jacks 13 to provide an operating pressure for actuating the firing pins, which pressure is derived from a primary cartridge or the like 24, when fired. In Fig. 3, a plurality of primary cartridges 26 are provided, situated at convenient points in the aircraft. Each cartridge can be fired by pulling its handle 25 against a spring 26, releasing a spring urged firing pin to detonate the cartridge and fill the passage 30 with gas under pressure. The firing pin of such jack 13 is spaced from its firing cap by a rubber ring. When passage 30 is filled with gas under pressure, the firing pin compresses the rubber ring and fires the jack to raise its piston 22. During the first part of its stroke, the piston 22 rotates two bell cranks 15 about pivots 15a to pull on two rods 14, which release fastenings of rails on which the hood slides (not shown). The remainder of the piston stroke raises the rails and hood into the airstream. As shown in Fig 4, the cranks 15 are also each connected by a link 16 to a plate 17 secured to a shaft 18 on which is secured a pinion 19 meshing with a rack 20. The rack can be moved manually to effect release of the rail fastings at any time. The primary cartridge may be detonated by the pilot pulling down a protective face shield which also operates ejector mechanism. The piston 22 of the jacks 13 may be formed in two telescoping portions.

Title: Improvements in or relating to methods of manufacturing semiconductor devices
IPC: H01L21/3063
Filed: 1965-06-29
Abstract: The area of a PN junction produced by alloying a wire to a semi-conductor body is reduced by etching the body while monitoring the forward current through the junction.  An N-type germanium wafer is soldered to a nickel electrode plate and a junction is produced by alloying the hemispherical end of a gold wire to the opposite face. The area of the junction is reduced by electrolytically etching the body in potassium hydroxide while passing a constant forward current through the diode and monitoring its voltage drop.  It is stated that the differential coefficient with respect to time of the voltage drop is inversely proportional to the square of the cross-sectional area of the remaining semi-conductor material. Suitable monitoring circuits are described which can be arranged to end the etching process when a desired cross-sectional area is attained.  If required further controls can be included to commence etching the next diode when the first has been completed.
