Title: Thermoplastic linear polysulfonates
IPC: C08G75/24
Filed: 1962-02-09
Abstract: New polysulphonates, having carboxyl groups or alkali metal carboxylate groups in side chains, are made by condensing a metal salt of 4,4-di-(4-hydroxyphenyl) -nvaleric acid of formula <FORM:0978290/C3/1> dissolved in aqueous media with a diacid halide of an aromatic disulphonic acid which is dissolved or dispersed in a water-immiscible organic liquid (e.g. a chlorinated aliphatic hydrocarbon and/or a benzene or toluene).  The disulphonyl halide used preferably has the formula <FORM:0978290/C3/2> wherein Hal is chlorine or bromine; Ar is an aromatic group; X is an alkylene group, alkylidene group, sulphur-containing radical (e.g. -S-, -SO- or -SO2-), ether radical, carbonyl or tertiary amino radical, or may be two or more alkylene or alkylidene groups which are bound together by an aromatic radical, a tertiary amino radical, an ether radical or by a sulphur-containing radical; R is an alkyl, aryl, aralkyl, alkyl-substituted aryl or cycloaliphatic group (any of which may be halogen substituted); Y is a halogen atom, a nitro group or an OR1 or R1 radical wherein R1 is as defined for R; n is O or an integer; m is O or an integer; p is an integer; q is O or 1; and r is an integer or may be O if q also is O. Catalysts for the reaction are tertiary sulphonium compounds and quaternary ammonium, phosphonium and carbonium compounds. At the end of the condensation, the polysulphonate may be precipitated from its solution in the aqueous layer with hydrochloric acid. The salt forms of the polysulphonates are soluble in water and aqueous alkaline medium (e.g. in photographic developing baths) and the acid forms are soluble in ethanol, acetone, dioxane, methylene chloride, tetrachlorofurane, dimethyl formamide and tetrahydrofurane and in mixtures of ethylacetate and tetrahydrofurane, alcohol and dioxane, ethyl acetate and isopropanol, and alcohol together with ethyl acetate and isopropanol.  The polysulphonates are useful in the manufacture of film and fibres; binding agents in photographic anti-halotion layers, antistatic layers and protective layers; and as sizing agents and antistatic agents.  In examples, in which reaction is effected in the presence of methylene chloride, aqueous sodium carbonate or sodium hydroxide solution and triethylbenzyl ammonium chloride, polysulphonates are obtained by reacting together 4,4-di-(4-hydroxyphenyl) -nvaleric acid and (1) 1,3-dichlorosulphonyl benzene; (2) 1,3-dimethyl-4, 6-di-chlorosulphonyl benzene; (3) 1,3-dichlorosulphonyl benzene and 4,41-dichlorosulphonyl di-phenyl; (4) 1,3-dimethyl-4, 6-dichlorosulphonyl benzene and 1,3-dichlorosulphonyl benzene; (5) 1-methyl-2, 4-dichlorosulphonyl benzene; (6) 1,3-dichlorosulphonyl benzene and bisphenol A; (7) 1,3-dichlorosulphonyl benzene and 2,21-dichlorosulphonyl diphenyl.

Title: Improvements in the method of and apparatus for making plywood
IPC: B27G11/00
Filed: 1932-02-27
Abstract: In the formation of plywood, adhesive particles in a dry or moist condition are distributed uniformly on plies carried by a conveyer beneath a vibrating sieve which forms a shower of particles.  A plasticizing liquid, such as water, is simultaneously or subsequently applied, the assembled plies being afterwards bonded together by pressure.  Plies 21, Fig. 4, from a pile 22 are placed on a conveyer 20 and are carried beneath a box-like distributer 24, having a perforated base and containing dry adhesive, which is reciprocated by an eccentric <PICT:0399470/III/1> <PICT:0399470/III/2> <PICT:0399470/III/3> driven by belt gearing from the conveyer shaft. Adjustment of the amount of adhesive fed may be effected by a coned pulley drive for the eccentric.  Moistening of the adhesive is effected by a sprayer 31 consisting of a pipe 36, Fig. 5, supplying a current of air and extending across the width of the plies, water being supplied by a perforated valved pipe 33 mounted in the pipe 36. The spraying may take place after the scattering of the adhesive or simultaneously therewith by directing the spray into the falling stream of adhesive.  In assembling three-ply veneer, three piles of plies 22, 26, 30 are provided and two adhesive distributers 24, 28 and moistening devices 31, 32.  To avoid the deposition of adhesive on the conveyer, the continuous conveyer 20 is replaced by a series of conveyers 53, 54, 66, Fig. 13, the adhesive distributers 52, 67 being situated over the spaces therebetween.  Screens 58, 59 are provided on each side of the distributers and sprayers 75 inject moisture through gaps therein, air being supplied by a common trunk 78 and water by pipes 75; adhesive is supplied to the distributers by hoppers 70, 71.  In a modified arrangement, two separate conveyers may be arranged in parallel, a ply being supplied with adhesive on each one and subsequently superposed, after which the third ply is placed n position.  Where the wood of the core ply is different from that of the back and front plies, adhesive is supplied only to the core ply.
