Filed: 1965-08-03
Abstract: 1,144,163. Fluorocarbon elastomer compositions. MINISTER OF TECHNOLOGY. 3 Nov., 1966 [3 Aug., 1965; 30 Nov., 1965 (2)], Nos. 33119/65, 50766/65 and 50767/65. Heading C3P. A sealant composition includes a low molecular weight fluorocarbon elastomer and a high molecular weight fluorocarbon elastomer of which at least the low molecular weight fluorocarbon elastomer has been chemically modified so as to introduce therein unsaturated carbonto-carbon linkages. A preferred composition includes a low molecular weight fluorocarbon elastomer containing unsaturated carbon-tocarbon linkages and a high molecular weight fluorocarbon elastomer. The terms " high and low molecular weight " mean average values of less than 20,000 and greater than 40,000 respectively. The compositions may be prepared by chemically modifying a low molecular weight fluorocarbon elastomer, e.g. by dissolving the elastomer in an alkyl substituted amide solvent wherein it reacts with the solvent and undergoes a process of dehydrofluorination or by allylation, so as to introduce therein unsaturated carbon-to-carbon linkages and blending the resulting elastomer with a high molecular weight fluorocarbon elastomer. In the examples are used copolymers of hexafluoropropylene and vinylidene fluoride with or without tetrafluoroethylene, Friedel-Crafts resin (a high molecular weight resin based on diphenyl oxide and dimethyl ether of p-xylylene glycol), medium thermal black, magnesium oxide, dicinnamylidene-1, styrene, diallyl phthalate, a linear polyamide resin, triethylene tetramine, and hexamethylene diamine.

Title: Improvements in pressure regulators for automatic musical instruments, piano players and the like
Filed: 1921-12-09
Abstract: 180,293. Welte & S÷hne Ges., M. May 23, 1921, [Convention date]. Blowing and exhausting air.-An air tension or pressure regulator comprises a governor-valve controlling two other valves, one of which only operates to decrease the tension or pressure. In Fig. 1 the regulator is shown arranged for connection to suction at D<1> and to the action at F<1>. The governor-valve A is connected to a diaphragm m<1> in the outer wall of an .auxiliary chamber E and to a spring G the tension of which is under hand or automatic control. The chamber E has a restricted passage H communicating with the atmosphere. Increasing the tension of the spring G causes decrease of pressure in the chamber E and consequent rising of a diaphragm m<2> which opens the valve B attached thereto to a greater extent, and increases the tension in the action. Diminishing the tension of the spring G allows the valve A to approach its seat, the pressure in the chamber E thereupon rising. Both diaphragms m<2>, m<3> are therefore depressed, the diaphragm m<2> partly closing the valve B to decrease the suction and the diaphragm m<3> opening the valve C and directly admitting atmosphericair thus instantly diminishing the tension in the action. The valves are arranged conversely when: the instrument is operated by pressure.

Title: Improvements in the manufacture of opacifiable photosensitive glasses
IPC: C03C4/04
Filed: 1947-12-16
Abstract: 636,151. Photo-sensitive glass. CORNING GLASS WORKS. Dec. 16, 1947, No. 33148. Convention date, Dec. 8, 1943. [Class 98 (ii)] [Also in Group XXIII] A transparent glass which becomes opacified on heating (to 500-600 C.) contains fluorine and copper, silver or gold in amounts equivalent to .01-1 per cent Cu 2 O, .05-.3 per cent AgCl and .01-.03 per cent Au. The glass is also thermosensitive in that if, before it is heated, it is exposed to short-wave radiations, e.g. ultraviolet, a colour develops on heating. The colour developed depends on the sensitizing agent (Cu, Ag or Au), the time and intensity of the irradiation and the time and temperature of the heating and ranges from blue, lavender, purple, maroon, to yellow, amber and red. By masking portions of the glass during irradiation an opacified pattern in colour on an uncoloured opacified background develops on heating; the mask may be a photographic negative in. which case there is formed in the glass a heat-developed coloured photographic image on an opacified background like a positive print. The negative emulsion should be on u.v.-transmitting glass or directly on the glass in which the positive image is to be developed. Examples of batches are given; they include s odium-silico- or alumino-fluoride as the opacifying agent and some include one or more of the following: Ce0 2 , BaC0 3 , SrC0 3 , ZnO and SnO 2 . A reducing agent is added to the batches for the copper glasses and an oxidizing agent may be added to the batches for the gold and silver glasses. The glasses may contain Au and Ag together, but not Cu with Au and/or Ag.

Title: Improvements in and relating to the production of fused ring polycyclic aryl sodium compounds
IPC: C07C63/44
Filed: 1959-10-02
Abstract: Fused ring polycyclic aryl sodium compounds in which the sodium atom is directly attached to a carbon atom in a ring are prepared by reacting a fused ring polycyclic aryl halide with metallic sodium at a temperature no higher than 10 DEG C. in an inert atmosphere. Preferably the sodium is used in fine division in a liquid and the reaction is carried out in an inert atmosphere such as argon or dry nitrogen at a temperature below 0 DEG C.  The liquid in which the sodium is dispersed may be an aliphatic ether containing from 2 to 12 carbon atoms, an ether of ethylene or diethylene glycol, a cyclic ether such as tetrahydrofuran or dioxan, a diphenyl ether of ethylene or diethylene glycol or a tertiary amine.  The liquid may be diluted by addition of an inert hydrocarbon liquid, but these inert hydrocarbons are not suitable for use alone in the process.  It is preferred to use less than the stoichiometric amount of aryl halide. Typical compounds which may be prepared include naphthyl sodium, pyrenylsodium, anthrylsodium, phenanthrylsodium, benzanthrylsodium, benzphenanthrylsodium, dibenzanthrylsodium, naphthoanthrylsodium, dibenzphenanthrylsodium, naphthophenanthrylsodium, fluoranthrylsodium and perylenyl sodium.  Fused ring polycyclic aryl carboxylic acids may be prepared by pouring the suspension of the polycycic aryl sodium compound on to solid carbon dioxide, dissolving the sodium salt so formed in water and hydrolysing with hydrochloric acid.  The carboxylic acid may be extracted with and recrystallised from organic solvents.  The following acids are specifically prepared: alphanaphthoic acid (Exs 1, 2), pyrene-3-carboxylic acid (Ex 3), 9-anthroic acid (Ex 4), and phenanthrene-9-carboxylic acid (Ex 5).

IPC: G21C1/07
Filed: 1965-08-05
Abstract: 1,135,396. Reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 25 July, 1966 [5 Aug., 1965], No. 33491/65. Heading G6C. A downward coolant flow, pebble bed nuclear reactor has a fissile pebble bed supported by, but spaced above, a base-plate and a disposition of coolant outlet ducts such that a downward flow of coolant through the bed changes direction from vertically downward to transverse within the spacing between the pebble bed and the base-plate. In the embodiment described, the core aggregation 12 of a gas-cooled pebble bed reactor consists of graphite marbles 13 in which fissile fuel particles are embedded. Replacement marbles are added at the top of the reactor vessel 11 whilst irradiated marbles the withdrawn from underneath through a pipe 15 under the control of a valve 14. The core aggregation 12 is supported on a support aggregation 16 permeable to coolant and consisting of secondary graphite marbles 17 which also extend up the sides of the core aggregation 12 to serve both as a containment for the aggregation 12 and as a neutron reflector. The support aggregation 16 is carried upon a diagrid 18 peripherally supported by the reactor vessel 11. The permeability to the coolant of the support aggregation 16 is reduced except along a preferential path for the heated coolant from the core aggregation 12 by disposing small refractory marbles 20, either freely or spot welded, in the spaces between the secondary marbles 17. The coolant travels along this preferential path to outlets 19 in the reactor vessel 11 situated above the diagrid 18, the diagrid thus being shielded from exposure to the hot coolant. The secondary marbles 17 may be spot welded to each other, and possibly also to the small marbles 20, to give a rigid support aggregation. Also the marbles 17 may contain fertile material to provide a breeding reactor system, but in this case they would not be joined together so as to facilitate discharge for chemical extraction of the bred fuel.

Abstract: 801,335. Twisting and crimping yarns &c. BRITISH NYLON SPINNERS, Ltd. Nov. 3, 1956, No. 33598/56. Addition to 797,051. Classes 120(2) and 120(3) In a process for imparting false-twist to a running filament according to the parent Specification, the ratio of the filament speed to the surface speed of that part of the rotating internal surface with which the filament makes contact is not less than 0.5. Such false-twisting may be applied to a process for crimping a thermoplastic filament or continuous filament yarn wherein the filament is heated over succeeding lengths of itself while in the highly twisted state to an extent sufficient to set the twist therein whilst the filament is allowed to contract by at least 2 per cent, these lengths are cooled before untwisting, and the filament is untwisted and then wound under low tension. In examples, nylon yarn is led from a supply package to a tension device, through an infra-red heater in which the heating element, e.g. an electric resistance, is positioned along one focus of an elliptical reflecting tube and yarn passes along the other focus, then through an air space constituting cooling means, to a falsetwisting device comprising a twisttube which the yarn enters along a path, the projection of which is at an angle of at least 80 degrees to the projection of the axis of the tube, to run in steady contact with inner peripheral surface of a rubber bush on one side of the axis and leaves along a path at a similarly defined but smaller angle, thence to draw-off rolls, between which and the tension device a contraction of up to 4.2 per cent is permitted.
