A process for simultaneously treating running lengths of gel pellicles comprises casting a pair of wet gel pellicles to form a double web with the pellicles in face to face contact, separating the individual pellicles of the web and contacting them with a bath containing a separation agent, reuniting the pellicles, partially drying to a moisture content of between 12 and 30% by weight, thereafter separating the pellicles, continuing the drying, reuniting the pellicles and after applying a coating to the outer surfaces of the double web so formed, drying the coated surfaces and finally separating the individual coated pellicles. The outer surfaces of the double web may be coated with an anchor coating, e.g. melamine- or urea-aldehyde condensate, prior to further coating with a moistureproof and/or heat sealing coating. The separation agent may be any organic substance whose molecules consists of, or comprises as a predominating part thereof, an essentially non- polar constituent, or any extremely finely divided water-insoluble particulate inorganic or organic substance or mixture thereof. The pellicles may be of regenerated cellulose, viscose cuprammonium, methyl, ethyl or hydroxyethyl cellulose, mixed ethers thereof and other hydrophilic materials, cellulose acetate or other cellulose esters, vinyl resins, e.g. polyvinylidene and polyvinyl chloride polyacrylonitrile and copolymers thereof with vinyl chloride, vinyl acetate, methacrylonitrile, 2-vinyl pyridine, 5-methyl-2-vinyl pyridine or mixtures thereof, copolymers of vinyl chloride with acrylonitrile and vinyl acetate; polyethylene, nylon, casein, prolamines and other proteins.

Title: The preparation of oxygen-containing organic compounds
IPC: C07C45/36
Filed: 1966-05-24
Abstract: Oxygen-containing derivatives of unsaturated compounds are prepared by reacting a compound, (a) R1CH=CHR2, wherein R1 and R2 are hydrogen, cyano or organic groups not containing amino or mercapto groups and the -CH=CH- is not directly linked to oxygen or S-R3, where R3 is hydrocarbon, but wherein R1 and R2 may be linked to form a cyclic compound or (b) R4R5C=CH-CHR6R7, wherein R4 and R5 are an electron-donating organic group and R6 and R7 are hydrogen or alkyl, with an alcohol which is free of any hydroxy-substituted aromatic group, in the presence of a noble metal of Group VIII of the Periodic Table and an inhibitor in a concentration of at least 40% by weight of the noble metal compound and any promoter present, with water, if present, being not more than 30% by volume.  The inhibitor is a monohydric or polyhydric aromatic hydrocarbon with hydroxy groups substituted on the aromatic nucleus, or an alkylated or halogenated derivative thereof, e.g. phenol, p-cresol, p - octylphenol, 2,6 - di - tert. - butyl - 4 - methylphenol or 2,4,6-tribromophenol, hydroquinone, catechol, pyrogallol or tetrafluorohydroquinone; an ether-phenol, e.g. p-methoxyphenol and p-benzyloxyphenol; a quinone or an alkylated or halogenated derivative thereof, e.g. quinone, 1,4-naphthoquinone and chloranil; a phenol or alcohol carboxylic acid, e.g. digallic and ascorbic acid or a triaryl amine, e.g. triphenylamine.

Abstract: 926,760. Linkwork conveying rotary motion; toothed gearing. P. VULLIEZ. Oct. 19, 1960 [Oct. 20, 1959; May 3, 1960; June 27, 1960], No. 23228/62. Divided out of 922,247. Classes 80 (1) and 80 (3). In a mechanism for rotating a shaft 9, Fig. 3, in a fluid-tight chamber, a transfer member 12 closing the open end of a flexible bellows 6 of metal or other material sealed to the chamber wall is gyrated, without rotating, by means such as a crank-pin 11 on an external drive-shaft 22 and is coupled to the shaft 9 by a second crankpin 11 or by epicyclic gearing, rotation of the member 12 being positively prevented by a coupling 26 of Oldham type between the member 12 and a fixed cover 21. The coupling 26 comprises a disc having on its upper face a first diametral groove engaged by a guide on the cover 21 and on its lower face a second diametral groove, perpendicular to the first groove, engaged by a guide on the transfer member 12. In a modification a gyratory transfer member 12, Fig. 9, which has internal teeth epicyclically engaging a pinion 10 on the driven shaft is rotatably mounted in an eccentric bore in a rotatable driving member 11 having external teeth engaged by a driving worm 40; the transfer member 12 is held against rotation by an Oldham coupling 26 which may have needle roller beds. Where a small angular movement (rather than full rotary movement) is to be transmitted, blind crank pin bores, similar to those in Fig. 3, are formed eccentrically rather than concentrically in the transfer member so that the upper and lower ends of the bellows are coaxial at one point in the angular movement, e.g. in the mean position. In a modification of this arrangement the transfer member, Fig. 14 (not shown), which is held against rotation by an Oldham coupling has an upstanding eccentric boss in which a blind bore for the lower crankpin is provided, the boss itself engaging an eccentric bore in a rotatable driving member. In a modification (Fig. 17, not shown) a gyratory drive for the transfer member, which is held against rotation by a first Oldham coupling as in Fig. 3, is provided by the intermediate member 56, Fig. 15, of a second Oldham coupling between parallel gear rings 54, 55 driven in the same direction by a common pinion (not shown), the member 56 having a central bore (not shown) rotatably engaged by the transfer member so that the latter is gyrated as the rings 54, 55 rotate. The transfer member is coupled to the driven shaft in the sealed bellows by epicyclic gearing as in Fig. 9.
