Title: Flexible and Hydrophilic POlyurethane Foam and method of making same
IPC: C08G18/40
Filed: 1968-04-30
Abstract: 1,180,321. Flexible, hydrophilic polyurethane foams. ELEKAL. 30 April, 1968 [2 May, 1967], No. 20518/68. Headings C3C and C3R. A flexible and hydrophilic polyurethane foam consists of a polyurethane based on a polyether or polyester polyol, has an open-cell structure and contains 5 to 20% by weight, based on the polyol, of an alkali metal salt of carboxymethyl hydroxyethyl cellulose in the form of fine particles homogeneously distributed in the pores of the polyurethane. It is suitably prepared by reacting in one-shot a polyether or polyester polyol at ambient temperature with an organic polyisocyanate in the presence of water, a fatty acid salt of divalent tin, a tertiary amine, a surface active agent and the alkali metals salt of carboxymethyl hydroxyethyl cellulose. It is preferred to mix the cellulose derivative with the polyol to form a binary mixture, which has the tin compound, tertiary amine and surface active agent added to it before or while causing the reaction with water and the polyisocyanate. Preferably the alkali metal salt of carboxymethyl hydroxyethyl cellulose is the sodium salt formed on the carboxymethyl groups and is used suitably in the form of a powder the particles of which have a diameter less than 0À2 mm. To impart a soft and pleasant feel to the foam it may be immersed in a bath containing an aqueous solution of a metal salt having a valency of at least two followed by wringing the foam and rinsing it in clear water. The preferred metal salt is aluminium nitrate.

Abstract: 531,279. Compound sheet materials. BRITISH CELANESE, Ltd. July 15, 1939, No. 20636. Convention date, July 23, 1938. [Class 140] Compound sheet material for wall and ceiling coverings comprises a paper backing receptive to aqueous adhesive and an ornamental fabric facing united by means of a layer of a thermoplastic derivative of cellulose or synthetic resin containing the vinyl radical. Paper such as cheap wallpaper coated with the cellulose derivative may be united to the fabric by heated nip rolls. The cellulose derivative coating preferably contains 60-200 parts of plasticizer to 100 parts of cellulose derivative and no volatile solvents, and is preferably 0.002 inch thick. The suitable thermoplastic compounds include cellular esters or ethers, mixed esters, and etheresters, polymerized vinyl alcohol, acetate or chloride, crotonol, methyl methacrylate, acrylic acid or mixed polymers. Plasticizers, dyes, pigments, lakes, fillers, oils, soaps and resins may be added. The coating is preferably applied to the paper as described in Specification 523,231. An example describes calendering the thermoplastic material in a five-roll vertical calender and passing the heated paper and the film through nip rolls. This laminated sheet is then passed while the film is still soft through heated nip rolls together with the fabric, and the product is then drawn over a chilling roller and wound up. The fabric may be woven, knitted or napped fabric of cellulose derivatives, cotton, silk, wool, linen or regenerated cellulose and may be coloured, printed or treated to produce a modified lustre.

Abstract: 205,912. Lamoureux, J. O. Aug. 1, 1922. Stamp-cancelling machines.-Letters are fed to the cancelling-member in overlapping relation so that only the stamp-bearing portions are printed on. Letters stacked on a table 1 against a partition 5 are fed forward by rollers 6, 7, between a guide 5<a> and spring fingers 14, 15, to feed rollers 21, 22 and thence between the printing- disc 4 and impression roller 35. The rollers 6, 7 are driven at a higher peripheral speed than the rollers 21, 22 and the disc 4, so that the letters reach the disc in overlapping relation. The distance from a side plate 10 on the table 1 to the rollers 21, 22 is approximately the length of the shortest letters to be handled, and to the rollers 4, 35, the length of the longest, the rollers 21, 22 being thrown out of action when the longest letters are being cancelled. The amount of overlap may be varied by altering the relative speeds of the rollers or by varying the pressure against the feed-rollers 6, 7, e.g. by increasing the stack of letters. Specification 200,609 is referred to.

Patent GB-941949-A (GB)
Title: Improvements in or relating to a process for the production of dimers of neopentyl polyhydric alcohols
IPC: C07C31/18
Filed: 1960-06-17
Abstract: A dimer of a neopentyl polyhydric alcohol is prepared by forming a partial ester of the polyhydric alcohol by heating the alcohol with an alkanoic acid containing from 1 to 18 carbon atoms, or an anhydride thereof, in an amount of from 0.5 mole to a number of moles one less than the number of hydroxyl groups in the alcohol per mole of alcohol, heating the partial ester in the presence of an acid dehydration catalyst until from 0.1 to 0.4 mole of water of esterification has been evolved for each mole of the partial ester, thereby forming a mixture comprising esters of the polyhydric alcohol and the dimer of the polyhydric alcohol, heating this mixture with a monohydric alcohol containing 1-18 carbon atoms to form a mixture comprising the polyhydric alcohol, the dimer of the polyhydric alcohol and an ester of the monohydric alcohol, separating the polyhydric alcohols from this second mixture and thereafter isolating the dimer.  The process is particularly applicable to the preparation of dipentaerythritol.  The pentaerythritol which does not react may be used to produce additional quantities of dipentaerythritol. The esterification may be carried out in the presence of an esterification catalyst such as phosphoric acid or an organic sulphonic acid. The dehydration (or esterification) of the partial ester may be carried out in the presence of alkane sulphonic acids, phospheric acid, or a cation exchange resin.  The process is described with particular reference to the preparation of dipentaerythritol from pentaerythritol but it is also suitable for the preparation of dimers of trimethylolethane and trimethylolpropane.

As shown in Fig. 2, the pickers 10 are provided with pivoted sections 10<d> which fill the gap between the parts 10 to apply adhesive to the whole surface of the label, and are moved out of the path of the presser arm by the engagement of extensions 10<e> with cams 15. The pickers 10 may extend over the whole surface of the label, in which case they are similarly pivoted. In the form shown in Fig. 4, for applying a separate label to an angular or inclined surface, the pickers comprise stepped surfaces united by inclined surfaces 10<h>. In this case, the gumming roller is resiliently mounted on its arm, carried by an arm with a resilient joint, so as to apply adhesive to the stepped surfaces.

Abstract: 1,060,405. Grinding. IMPREGNATED DIAMOND PRODUCTS Ltd. April 29, 1965 [May 25, 1964], No. 21532/64. Heading B3D. A method of manufacturing diamond impregnated moulded tools comprises forming at least that surface of a mould against which the operative face of the tool lies during a moulded process with an indented finish whereby an indented roughened surface is provided on the operative face of the tool by the moulding operation, the indentations of the mould surface being such as to produce indentation of a depth of at least 0.020 inch in the tool. The moulding process consists of. mixing diamond particles with powdered metal in a mould, levelling the mixture and adding a layer of metal powder which forms a backing. The mould is then heated and pressed. The tool may be in the form of a rod of square section or a ring when taken from the mould and is then cut into segments for attachment to the face of a saw, grinding wheel or other face tool. In order to avoid the initial flat-glazed surface, the surface of the mould facing the operative face of the tool is formed with the indented finish by milling, slotting, grinding or spark eroding using a wire mesh as an electrode or a machined block of graphite. The indented surface may be in the form of a straight or cross hatch. The segments (11, Fig. 1) may be of arcuate form secured to the face of a stone rubber 10, each segment being moulded with a chamfer and a roughened surface of cross-hatch configuration. In another embodiment, the segments (21, Fig. 3) are secured to the periphery of a circular saw and have a crosshatched surface formed with indentations.
