Abstract: 1,150,367. Purifying gases. METALLGESELLSCHAFT A.G. 10 Oct.. 1967 [27 Oct., 1966], No. 46315/67. Heading BIL [Also in Division C1]  Activated carbon having a steep adsorption isotherm and which has been employed in removing sulphur from gases which contain sulphur in combined form, is regenerated by passing over it a hot, gas inert to carbon and sulphur e.g. nitrogen or methane. A suitable activated carbon has a surface area of 1200 to 1500 'square metres per gram, a most frequent void radius of 4 to 12, and a microvoid volume of about 0.8cc per gram (for voids having a radius less than 100A). Regeneration temperatures must not be below 300C, a temperaturebetween, 300 and 550C, being preferred. In a specific example (see Figure 2, not shown) a gas comprising 99% C02 and 1% HAS was purified and the activated carbon employed was regenerated using nitrogen (which may be recycled) at 500C, the flow of nitrogen through the carbon being reversed once during each regeneration.

Title: Electrolytic treatment method and apparatus
Inventor: CANN LEOPOLD
IPC: C25D21/12
Filed: 1962-12-07
Abstract: <PICT:1010799/C6-C7/1> In order to electrolytically plate or anodize a surface uniformly, a uniform current density is applied to the surface.  An electrode similar to that to be treated is divided into electrically isolated sections of equal area and subjected to electrolysis in a container 81.  The current density at the separate sections is determined using an ammeter 91 which can be connected to the different sections in turn.  To achieve a uniform current density, the position of electrodes 94, 95 is varied by moving their support framework which is adjustably mounted at 96, the configuration of the electrodes 94, 95 is varied or additional electrodes are used.  The sectioned electrode is then replaced by the object to be treated. Instead of using only one ammeter, an ammeter may be connected to each section.  Information storage devices may be made in this way by plating permanently magnetic material on to a copper screen as described in Specification 1,010,798.

Patent GB-1064490-A (GB)
Title: Improvements in or relating to dyeing of styrene polymers
IPC: C08J3/00
Filed: 1964-11-17
Abstract: Styrene polymer granules are dyed in aqueous dispersion with dyes which are insoluble in water but soluble in organic solvents by including in the dispersion at least 0.25% by weight, based on the polymer, of a "penetrant," and maintaining the dispersion under at least autogenous pressure at a temperature of 40-200 DEG  C. until the dye penetrates the polymer. Penetrants are substances or mixtures of substances which being liquid under the process conditions dissolve the dye and can penetrate the granules without altering the physical appearance thereof.  Where a mixture is used, only one of the components need be liquid under the process conditions.  Suitable penetrants include C1- 7 aliphatic hydrocarbons, those of their halogenated derivatives which boil below the softening point of the polymer and mixtures thereof.  If the proportion of such penetrants is 3-15% the dyed granules are expandable. Dye assistants such as epoxidized fatty oils may be used, preferred proportions being 1-2% of the polymer by weight.  Preferably, the process is carried out at pressures of 30-150 p.s.i.g. and 50-135 DEG  C. and in the presence of suspending agents such as polyvinyl alcohol, tricalcium diphosphate, dodecylbenzene sulphonate hydroxyethyl cellulose, and polyoxyethylene sorbitan monolaurate.  Specified dyes include various anthraquinone, azo and quinoline dyestuffs.  Exemplified polymers are polystyrene and a styrene/acrylonitrile copolymer and specified polymers include polymers and copolymers of styrene, divinyl benzene, vinyltoluene, isopropylstyrene, a -methylstyrene, dimethyl styrenes, chlorostyrenes, and vinyl naphthalene, as well as copolymers of these with minor amounts of monomers such as butadiene, isobutylene, acrylonitrile, methylmethacrylate and itaconic acid.  Where the polymer is prepared by dispersion or suspension polymerization, e.g. using styrene monomer in the presence of water, tetrasodium pyrophosphate and benzoyl peroxide and t-butyl perbenzoate as catalysts, the dye and penetrant may be added to the mixture when polymerization is substantially complete, but not before.  The dyed granules may be expanded by, for example, steam heat to produce moulded articles.

Title: Polyurethane foam

Abstract: 1530909 Polyurethane foam CARL FREUDENBERG 14 Nov 1975 [30 Nov 1974] 46979/75 Heading C3R [Also in Division Dl] A hydrophilic polyurethane foam in which the polyurethane contains branched polyethylene glycol units and polyester units is prepared by reacting together a branched polyethylene glycol adduct having isocyanate groups, a polyester having hydroxy and/or isocyanate groups and water. The polyester used is preferably a polyisocyanate adduct, having isocyanate groups, of a polyester having hydroxy groups, and may have a M.Wt. of 500-20,000. The polyester itself is preferably derived from one or more dicarboxylic acids and one or more alkylene glycols; or it may be a polymerized lactones, e.g. #-caprolactone. The polyethylene glycol may have a M.Wt. of from 200-20,000. Preferred polyisocyanates for making the branched polyethylene glycol adduct and the polyester isocyanate adduct are di- and triisocyanates, e.g. tolylene diisocyanate, 4,4<SP>1</SP>- diphenylmethane diisocyanate, 1,5-naphthalene diisocyanate, 1,6-hexamethylene diisocyanate, isophorone diisocyanate, triphenylmethane triisocyanate, trimethylolpropane/ tolylene diisocyanate adduct and 1,6-hexamethylene diisocyanate/H 2 O adduct. The foam may be applied to a textile sheet material, e.g. a woven, non-woven or knitted fabric, the weight ratio of textile sheet to wet foam generally being from 1 : 2 to 1 : 10 to give a coated or impregnated product having hydrophilic properties. In the example a non-woven fabric consisting of polypropylene fibres and viscose fibres is impregnated with a foam formulation prepared by mixing a branched polyethylene glycol adduct having NCO groups, and a poly(ethylene glycol) adipate adduct with water, the polyester adduct having been prepared by the reaction of a polyethylene glycol adipate with a liquid 4,4<SP>1</SP>-diphenylmethane diisocyanate/polycarbodiimide condensate.
