Title: Improvements relating to the treatment of hops
Inventor: MARSHALL JAMES EDWARD FREDERIC
IPC: C12C3/00
Filed: 1963-10-29
Abstract: <PICT:1082726/C6-C7/1> <PICT:1082726/C6-C7/2> A hop extract having a high lupulin content is produced by mechanically disintegrating hop material such as pressed whole hops, unpressed and unbaled hops or hop waste from a hop picking machine, the material preferably having been dried to about the same extent as whole hops intended for use in the brewing industry, and screening the disintegrated material to remove coarser particles therefrom, for example on a 50 or 80 mesh screen.  The disintegrated material may be subjected to a first screening using a screen of 30-50 or 15-25 mesh and a second screening using a screen of 60-100 mesh, and may then be further purified by screening through a screen of 100-120 mesh, by air classification or by winnowing.  The product normally has 50-90% content of lupulin corresponding to 15-29% of a -acid.  The rate and degree of disintegration should be such that 8-12% by weight of the hop material passes through the screen, or the first screen, used. Dispersion of the aromatic oils of the lupulin in beer is assisted by wetting the lupulin with aqueous alcohol or glycerol for 24 hours or more before its addition to the beer. The disintegrator may have taut stout wires 6, Fig. 3, mounted on a rotary shaft 3, a semi-cylindrical screen 13, Fig. 4, and a vibratory flat screen 14. Vents 16 covered with filter cloth and shutters 17 enable the air pressure in the disintegrator to be controlled.  The wires may be arranged at a small angle to the axis Fig. 2 (not shown) so that on rotation they exert a forwarding action on the hop material.  The wires are typically rotated at a linear velocity of 30-120 ft./sec. (say 800 or 1,500 r.p.m.) and the hop material is subjected to the disintegrating action for an average time of 5-30 seconds.

Title: Process for producing 1,8-dioximino-4,7-methano-3a,4,7,7a-tetrahydroindene
IPC: C08G59/40
Filed: 1959-12-16
Abstract: Dicyclopentadiene dioxime, specifically 1,8-dioximino-4, 7-methano-3a, 4, 7, 7a-tetrahydroindene, acts as a curing agent for epoxy resins.  In Example (6), a mixture of the diglycidyl ether of bisphenol-A, the dioxime and dimethylformamide is heated at 120 DEG C. for about an hour to give a dark-coloured solution.  A portion of this solution is brushed on an iron panel, and the coated panel is cured for 30 minutes at 160 DEG C. in an electrically-heated oven.  A very hard film is obtained, which is unaffected by acetone.ALSO:Dicyclopentadiene dioxime, specifically 1,8-dioximino - 4,7 - methano - 3a,4,7,7a - tetrahydroindene, is produced by reacting together cyclopentadiene, nitrosyl chloride and a solution of an alkali metal hydroxide in a lower alkanol, the alkali metal hydroxide being present in molar excess over the nitrosyl chloride, and then neutralizing the reaction-mixture with an acid, preferably carbon dioxide.  An inert organic solvent for the dioxime is preferably added to the reaction-mixture; suitable solvents are ethers and amides of higher boiling-point than the lower alkanol.  The preferred solvent is p-dioxane.  In an example, nitrosyl chloride is added to a solution of sodium hydroxide in methanol while maintaining the temperature at about -4 DEG C.  Cyclopentadiene is then gradually added, the temperature rising to 10 DEG C.  After 2 hours, p-dioxane is added, and the mixture is neutralized with gaseous carbon dioxide. The methanol is then removed by vacuum-stripping and the mixture is filtered; the p-dioxane is then evaporated from the filtrate and the dioxime is obtained as residue.  The dioxime is a curing agent for epoxy resins (Group IV(a)).

Title: Vulcanisable rubber-containing mixtures for tyre treads
IPC: C08L9/00
Filed: 1974-10-08
Abstract: The mixture comprises an elastomer component and a mixture of additives, including sulphur and/or sulphur donors and vulcanisation accelerators. The elastomer component comprises one or two polybutadiene rubbers and optionally further rubber, which may be synthetic and/or natural rubber. In order to achieve good grip of the tyre, the mixture has an unusually high content of active silica filler (more than 80% by weight, based on the elastomer content). Thanks to a content of specific sulphur-containing organosilicon compound, the mixture is nevertheless not too viscous for conventional processing and can be sprayed. It may also contain carbon black. In spite of the high filler content and a likewise high content of soft material (from 40 to 100% by weight, based on the elastomer content) of the mixture, the vulcanisate has the requisite rubber-technical properties, such as tensile strength and tear resistance. After vulcanisation, the rubber mixture gives tyre treads with good grip on wet, snow-covered and in particular icy roads.

[Also in Division G5] The record/read process is basically similar to that described in Specification 1,093,436, but is intended for forming permanent, non- erasible records. In one example 1Á of titanium is deposited on a glass plate and selectively oxidized so that the oxide varies from 300Š with blue light reflectance of 1% to 700Š, where the reflectance is 65%. In a second example, a thin layer of titanium or aluminium is supported on a plastics film, preferably sandwiched between two such films and bombarded by a laser beam to produce an oxide layer with modulated interference colour patterns. In a third example, an oxide is produced and then removed by vaporization to leave a light-modulating groove structure. In a fourth example, a titanium layer is selectively nitrided to vary its reflection of green light. In a fifth example, a Fabry-Perot filter is made of a platinum-group metal and is selectively treated with hydrogen to modulate its optical transmission and/or reflection properties.

Abstract: 1423149 Converting; protective arrangements PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 27 July 1973 [2 Oct 1972] 45283/72 Headings H2F and H2K In a power supply arrangement, e.g. for a television receiver, comprising a first switchedmode D.C. supply in which the conduction angle of a switching device such as thyristor D9 is controlled in dependence on the charging time of a capacitor C4 to provide a first D.C. voltage from which is derived a second substantially lower D.C. voltage D. In the event of a fault on the load associated with supply D, so as to reduce the voltage at D, the charging time of capacitor C4 is increased so as to reduce or cut off the first D.C. voltage. As described, the supply mains AB are fed to a bridge recitifier D1-D4 which feeds a full wave rectified voltage to the thristor D9. Capacitor C4 is charged via R6 during each half cycle until its voltage reaches that at the junction of R8, R9, when silicon controlled switch D8 breaks down, triggering the thyristor D9. The charging of C4 is controlled by TR1 and Zener diode D7, feedback via resistor R1 assisting in the stabilization. The first D.C. supply at 165V is fed to the line output stage comprising transistor TR2 which feeds deflection coils L3. The waveform from the line output transformer T2 is rectified at D10 to provide 30V to energize the low voltage circuits of the TV receiver. In the event of a fault on the low voltage side, the voltage at D becomes reduced so that diode D5 clamps the voltage at the emitter of TR1 so as to delay conduction of TR1 and hence delay the triggering time of thyristor D9 and hence reduce both D.C. voltages. Crowbar ocer-voltage and over-current protection.-A glow switch GS, of the type used in fluorescent lighting, is included which becomes ionized in the event of over-voltage so as to close its contacts and open the fuse F. Modifications.-Figs. 2-4 (not shown) depict variations in the connections between terminal D and TR1. D5 may be replaced by a Zener diode.

Abstract: 1396378 Measuring contamination electrically UNIVERSAL OIL PRODUCTS CO 5 Oct 1972 [6 Oct 1971] 45945/72 Heading G1N The build up of contamination in an environment is determined by allowing the contaminant to form on the surface of a resistance probe 3 and measuring the resultant change in its resistance. The probe is fed with current from a power source 1 and either the voltage drop V across the probe or the current I through it is maintained at a constant value by comparing the voltage V or the voltage drop across a series resistor 33 with a reference voltage 21 in a differential amplifier 11, using the difference to control the power source 1. The surface temperature of the probe 3 is sensed by a thermocouple 29 whose output is compared with a voltage 30 representing the uncontaminated surface temperature of the probe, any difference being amplified at 15 and added to the control for power source 1 to compensate for changes in probe resistance due to changes in probe temperature. It is shown that with a predetermined gain factor for amplifier 15, the change in current I when the voltage V is maintained constant, or the change in V when I is constant, is proportional to the change in resistance of the probe and is an indication of the contamination.
