Title: Epithio ethers, their preparation and polymers
IPC: C07D331/02
Filed: 1961-10-19
Abstract: The invention comprises epithio ethers having at least two <FORM:0968424/C1/1> groups, wherein R is hydrogen or a hydrocarbon radical, and at least one oxygen-ether linkage and derivatives thereof obtained by reaction with nucleophilic materials.  The group attached to the epithio groups may be aliphatic, cycloaliphatic, aromatic or heterocyclic, saturated or unsaturated and may be substituted with halogen atoms and ester and sulphonyl radicals.  The epithioethers may be prepared by the thermal dehydration of hydroxy-mercaptans, the treatment of 1,2-chlorothiols with alkaline solutions or the heating of a corresponding ethylenically unsaturated compound with sulphur or a compound that liberates sulphur on heating, but are preferably prepared by reacting an epoxyether with a thiocyanate, preferably an alkali metal thiocyanate or ammonium thiocyanate.  Specified epoxyethers are those obtained by reacting bisphenol and epichlorohydrin in the presence of aqueous sodium hydroxide or by reacting glycerol, diethyl ether, boron trifluoride and epichlorohydrin. Other epoxyethers mentioned are the polymers and copolymers of allylic ethers of epoxy-containing alcohols.  The epithioethers react with small quantities of nucleophilic material to form hard cross-linked water-insoluble infusible polymers (see Division C3) and with mono- and poly-functional reactants, e.g. amines, ammonia, acids, mercaptans and hydrogen sulphide, to produce monomeric derivatives.ALSO:Epithioethers having at least two <FORM:0968424/C3/1> groups, wherein R is hydrogen or a hydrocarbon radical, and at least one oxygen-ether linkage react, generally at around 25 DEG C. but preferably at 50 DEG  to 150 DEG C., with small quantities, preferably 0.1% to 10%, of nucleophilic material to form hard cross-linked substantially water-insoluble infusible polymers. The groups attached to the epithio groups may be aliphatic, cycloaliphatic, aromatic or heterocyclic, saturated or unsaturated and may be substituted with halogen atoms and ester and sulphonyl groups. Specified nucleophilic materials are acids, acid anhydrides, mercaptans, amines, ammonia and certain specified metal salts.  It may be desirable to employ solvents or diluents (for example ketones, esters or chlorinated hydrocarbons alone or in admixture with aromatic hydrocarbons and/or alcohols), including those which remain in the cured composition (for example diethyl phthalate, monoepithio compounds, monepoxides and cyano-substituted hydrocarbons), in the above reaction.  The polymers so obtained may be further combined with polyepoxides, polyurethanes, resins, polythiopolymercaptans, polyaldehydes, polyols, synthetic oils, cellulose derivatives, vinyl polymers, bituminous materials, tars, asphalts, plasticizers, stabilizers and fillers to form compositions suitable for use as surfacing compositions, adhesives and laminating compositions.

Abstract: 836,616. Photo-electric pin-hole detectors. GENERAL ELECTRIC CO. Dec. 28, 1956 [Dec. 30, 1955], No. 39485/56. Class 40 (3). A pin-hole detector comprises an elongated housing containing light - sensitive devices distributed along a longitudinal slot in the housing, each device having an individual sensitivity control and an associated reference light. Light from a mercury lamp 1, Fig. 1, passes through pin-holes in a tin-plate strip 3, into a detection chamber 2 by way of a longitudinal slot 2a. A mask 6 prevents the entry of stray light. Six photo-multiplier tubes 10-15, Fig. 5, are arranged in the chamber along each side of the slit. The chamber, which is painted in a highly reflective paint, also contains six neon lights, 16-21 arranged on its lower surface each opposite a tube. Direct voltages from the pi filter 38 are supplied to the dyanodes of the tubes through voltage dividers 32-37. The output from the tubes passes through an anode resistor 45 and a gain control potentiometer 49 to a three-stage amplifier comprising valves 46, 47, 48. The biases supplied to the valves are such that when the photo-tubes are dark the valves are conducting. The signal then passes through a single pulse multivibrator 54, 55, to a cathode follower 58, 59. A capacitor 61 is charged in response to the positive pulse at the output of the multivibrator. After charging, the capacitor discharges through a resistor 59 and potentiometer 60 at a rate determined by the setting of the latter. The first stage of the amplifier 63 is normally non-conducting and the second stage conducting to energize the relay 62. A signal reverses this state. The detector may be rearmed after operation by a multi-vibrator with rapid reset. To equalize the gain of the phototubes the chamber is closed to light and an electronic voltmeter plugged in at 45a. Buttons 24-29 are depressed in turn to operate the neon tubes and the reading recorded. The appropriate gain control potentiometers are adjusted accordingly.

Abstract: 972,466. Fuel elements. COMMISSARIAT A L'ENERGIE ATOMIQUE. Oct. 7,1963 [Oct. 26, 1962], No. 39507/63. Heading G6C. A nuclear fuel element comprising a tubular fuel rod clad internally and externally with metal sheaths connected by a thin annular plug enclosing the fuel, is characterized in that the inner surface of the plug has a larger area than the mean crosssectional area of the fuel rod. In Fig. 2 the tubular fuel 8a is clad with sheaths 10a 12a, of which the outer sheath 12a has a flared end. The plug 14a closes the ends of the sheaths and a spacing member 22 is interposed between the plug and the fuel rod. The member 22 may be of heat insulating material such as alumina, or may be of heat conducting material. A bearing ring 20a fits in a groove in the plug. The increased area of the plug improves its resistance to creep, and preferably one or both of its surfaces are roughened, as shown at 24, to prevent radial distortion and allow greater axial stresses. In an alternative construction, Fig. 3, the area of the plug 14b is increased by making it of frusto-conical form. In a further alternative, Fig. 4 (not shown), the outer sheath is flared, as in Fig. 2, and the plug is frusto-conical, as in Fig. 3.
