Title: Improvements in the production of cellulose compounds and the treatment of cellulosic textile materials
Filed: 1939-04-04
Abstract: 528,740. Cellulose derivatives. COURTAULDS, Ltd., and MORTON, T. H. April 4, 1939, No. 10506. [Class 2 (ii)] Cellulosic material is'subjected to treatment with an aqueous solution of formaldehyde containing a small proportion of an acid catalyst for a time less than 2 hours and at such a temperature that the reaction proceeds substantially to a state of equilibrium. The cellulose compound thus produced is separated from uncombined formaldehyde and acid catalyst and may then be subjected to drying. The proportion of the formaldehyde solution to the cellulose is at least such that the cellulose is always in a fully swollen state. When using a 40 per cent. formaldehyde solution containing sulphuric acid sufficient to give a normal solution the reaction is carried out for about 10 minutes at 80‹C., or for 1 hour at 60‹C. When using decinormal sulphuric acid with 40 per cent. formaldehyde the time is about one hour at 80‹C. Washing, of the product may be effected first with cold and then with hot running water. The cellulosic material may be in the form of cotton linters, bleached woodpulp, or yarn or fabric prepared from natural or artificial fibres. The products obtained may contain 3-4 per cent. or more of combined formaldehyde. The products may be combined with nitrogenous compounds such as cyanamide and salts of tertiary bases, e.g. pyridine and triethanolamine. By heating the products in the presence of an acid catalyst under dehydrating conditions, products of increased wet strength, increased resistance to creasing, and reduced water imbibition are obtained. Specifications 25647/06, [Class 2], and 528,741 are referred to.

Title: Improvements in or relating to flexible abrasive coated articles and the manufacturethereof
IPC: B24D11/00
Filed: 1935-02-22
Abstract: 434,186. Flexible abrasive articles. CARBORUNDUM CO., Ltd., Trafford Park Road, Trafford Park, Manchester.-(Carborundum Co. ; Niagara Falls, New York, U.S.A.) Feb. 22, 1934, No. 10632/35. Divided out of 433,880. [Class 60] [See also Group VIII] Flexible abrasive articles, such as sanding belts, are made by forming a non-uniform adhesive coating on a backing by localized pressure on the adhesive to prevent an adhesive coating on predetermined areas of the backing according to a regular pattern whilst permitting an adhesive coating on the remainder, applying granular abrasive to the coated surface and removing the less adherent grains from the backing. In the form of apparatus shown in Fig. 1, fabric is drawn from a roll 2 between a pair of rolls 3, 4. Adhesive is applied by the smooth roll 4 and projecting portions 6 of the patterned roll 3 press out adhesive from parts of the fabric leaving a coating on those parts lying opposite depressions 7. Abrasive grain is dropped on the fabric from a hopper 11 and excess is removed by bringing the fabric into a vertical plane, assisted by a beater 14. After drying, a sizing coating of adhesive may be applied. In the modification shown in Fig. 2, a uniform coating is first applied by rolls 3<1>, 4<1> and is made non-uniform by passing the fabric between a smooth roll 16 and a patterned roll 15. Fig. 3 shows a form of apparatus in which adhesive is applied by a patterned roll 4<11>, which may be provided with a scraper 22, the depressions 19 providing a full adhesive coating, while raised portions 21 squeeze out the adhesive from the remainder. A. transfer roll may be used to supply the patterned roll with adhesive from the container. An additional patterned roll 24, Fig. 5, may be used to press adhesive from additional areas on the fabric. In a further modification the roll 24 is patterned similarly to the roll 4<11> and is supplied with talcum powder from a supply roll so that the powder is deposited on those portions of the fabric from which adhesive has been pressed by the roll 411. The patterned rolls may be formed by embossing, engraving, knurling or attaching strips of materials to the surface.

[Also in Group XXVIII] In means for governing the rate of reciprocation of a reciprocating pump pressure impulses associated with the reciprocations control a valve 11 through its actuating diaphragm 22 spring-loaded at 23 to the open position, the valve supplying pressure fluid to the valve chest 15 of a reciprocating motor 13 driving the pump to maintain the reciprocation rate constant. Pressure impulses from one side 12 of the motor 13 actuate, via line 16, a diaphragm pump 4 pressurizing a chamber 5 having an adjustable leak-off valve 7, whereby increased chamber pressure due to faster reciprocation acts, via line 10, on diaphragm 22 to close valve 11 and reduce the air or steam to the valve chest 15 of the motor. Line 10 may contain a throttle and a downstream capacity chamber, the motor piston-rod may actuate diaphragm 4 through a lever, line 16 may contain a U-tube of sealing liquid, the pump diaphragm 4 may be replaced by a U-tube of liquid or the pump 4 may be omitted, the line 16 leading directly to chamber 5 via a check valve. In further embodiments the pump 4 may be provided with a separate liquid supply system (Fig. 9, not shown), valve 7 may be actuated by a diaphragm responsive to pressure in line 10, two pumps 4 in parallel may be worked from both sides of the motor piston and may control a valve supplying two motors. The pressure impulses may be derived from the reciprocating pump and all diaphragms replaced by pistons.
