Patent GB-1035934-A (GB)
Title: Photolysis of organic sulphur compounds
Inventor: BARTON DEREK HAROLD RICHARD
IPC: C07B60/00
Filed: 1962-04-03
Abstract: Free acyl radicals are generated by subjecting an acyl derivative of a dithiocarboxylic acid containing the group -CO-S-CS- and dissolved in an inert solvent, to irradiation in the wavelength range 300-500 mm .  The preferred acyl dithiocarboxylic acid derivatives are the xanthates of the general formula R-CO-S-CS-X where X is a C1- 6 alkoxy group and R is an aliphatic, cycloaliphatic, araliphatic or aromatic group which may carry one or more halogen, oxo or acyloxy groups or a further -CO-S-CS-X group as substituents.  The course of the subsequent reaction depends upon reaction conditions, particularly temperature and the presence or absence of other reactive substances. Thus, when the acyl radical RCO. is stable under the reaction conditions, i.e., if irradiation is effected below the thermal decomposition temperature of RCO., the radicals may react with each other to give a -diketones or with other compounds, e.g. olefins or thiols to give acyl or diacyl derivatives of olefines or thioesters of carboxylic acids.  If the temperature is sufficiently high, the acyl radicals decompose to R. radicals and carbon monoxide. The R. radicals may condense with each other to give R-R or may react with other compounds, e.g. thiols to give thio ethers, or with the .S-CS-X radicals present to give esters R-S-CS-X which may be hydrolysed to thiols RSH.  The preferred light source is Hg vapour lamp and the preferred wavelength 400 mm .  Photolysis is conveniently effected at the reflux temperature of the solvent which may be, e.g., cyclic or acyclic ether, aromatic hydrocarbon or a chlorinated hydrocarbon.  Examples describe the irradiation O - Et - S - phenylacetyl xanthate, alone and in the presence of benzyl mercaptan, O-Et-S-isobutyryl - xanthate, O-Et-S-trimethylacetyl xanthate, O-Et -S-n-valerylxanthate, O-Et-S-acetylmandelyl-xanthate, alone and in the presence of benzyl mercaptan, O-Et-S-benzoylxanthate, O-Et-p-chlorobenzoylxanthate and O-Et-3b  - acetoxy - 11 - keto - bisnorallo-cholanoyl-xanthate.  The starting materials are made by reacting the appropiate acid halide with an alkali metal salt of the dithiocarboxylic acid; some thioanhydride may also be obtained.  3b  - Acetoxy - allopregnan - 11 - one io prepared by treating 3b -acetoxyallopregnan-11,20-dione with ethylenedithiol and BF3 to give 3b  - acetoxyallopregnan - 11,20 - dione 20-ethylenedithioketal and then refluxing this with Raney nickel in ethanol.  3b  - Acetoxy - 11 - ketobisnorallocholanoyl chloride is prepared from the acid and oxalyl chloride.

Filed: 1936-05-06
Abstract: 474,765. Creels. BRITISH CELANESE, Ltd., and POOL, W. May 6, 1936, No. 12793. [Class 142 (iv)] Flanged bobbins, spools, cheeses, cones, &c., supplying yarns to warp mills &c., are supported by and rotate on vertical spindles 10 having hardened steel cone points at each end supported by bearing cups 9 on flat strips 3, 7 riveted to the upper and lower flanges of channel irons 2 connecting a pair of vertical channel irons 1. To allow a spindle to be snapped into position one or both cups may be mounted on spring holders. In the arrangement shown, the strips 3 have spring portions. Guide channels 11 may be provided on the strips to permit the spindle to slip readily into position. Each bobbin &c. rests on a felt friction washer &c. 14 on the base 13 of the spindle, which is thus driven frictionally by the bobbin &c. The yarn passes from each bobbin through a porcelain hook 17 supported on a wire 18, the two ends of which pass on opposite sides of a vertical wire 15 and are looped at 19, 20 around a second vertical wire 16. During unwinding the guide moves up and down, but if a yarn breaks, it falls and a projecting part 21 thereof moves into the path of one of a pair of projections 22 on the base of the spindle, the rotation of which is thereby stopped. From the guides 17, the threads pass to horizontal guides on projecting portions of the strips 3 and on to eyes 25 on horizontal projecting plates 26. The projecting portions of the strips 3 support slack threads and have lips to prevent these from falling off. Half the threads are delivered from each side of the creel. Several creels may be used side by side disposed to taper slightly towards the warping mill. The guides may be of unglazed porcelain. When bobbins are used which have two or more threads wound together, two or more hooks 17, Fig. 4 are used, one for each thread. According to the Provisional Specification the upper pivot cup may be springy and the plate for the lower cup be stiffened by a flange. The spindles may comprise sleeves.

Title: Improvements in or relating to the bonding of a ceramic part to a metallic part
IPC: C04B37/02
Filed: 1961-04-11
Abstract: A method of bonding a metal part to a ceramic body comprises heating in an inert atmosphere an assembly of the two and between them a first and a second different metallic layers, the first of which, adjacent to the ceramic body, being a reacting material e.g. Zr or Ti, the second adjacent to the metal being a metal, e.g. Au, Au-Ag, Ag-Cu, Au-Ni, capable of soldering to or alloying with the metal body the heating being at a temperature such that a solid metal separating layer, either initially separate or formed by part of the second metallic layer, is present at all times, eutectics being formed between the separating layer and the first metallic layer and the <PICT:0979811/C1/1> <PICT:0979811/C1/2> second layer or the metal part.  Fig. 2 shows a Ti-foil 10 and a Cu-foil 9, placed between a metal body M and a ceramic body K. After heating, when the assembly is cooled the composition of the metal layers change as shown below the line BB1.  The foil 9 forms an alloy 911 with the metal M, the foil 10 bonds to the ceramic K and forms an alloy 101 with the foil 9; between 911 and 101 a barrier layer 91 is created by alloying of the foils 9 and 10. In an alternative arrangement shown in Fig. 1, there is provided a hard metal foil 1, a reacting metal 3 and an intermediate metal foil 2. After heating, the foil 2 bonds to M and alloys with 2 changing to 11 while the foil 3 bonds to K and changes in composition to 31 by alloying with 2, forming a similar barrier layer 21.  The barrier layer is stated to prevent the reactive layer and the hard solder layer from forming a homogeneous, brittle metal and thus makes it possible for the hard metal to take up forces resulting from the different coefficients of expansion of the ceramic and the metal body when temperature changes occur.
