Title: Improvements in or relating to Cellulosic Textile Materials
Inventor: CAMPBELL HUGH J E
IPC: D06M15/423
Filed: 1966-03-30
Abstract: 1,163,525. Treating cellulosic materials. ONTARIO RESEARCH FOUNDATION. 28 June, 1967 [30 March, 1966], No. 14185/66. Heading D1P. Cellulosic textile materials, e.g. fibres, yarns or fabrics of cotton or viscose rayon alone or in admixture with polyester fibres, are creaseproofed and creases or pleats inserted therein are rendered permanent by contacting the textile material with formaldehyde and cyanamide in the presence of water and reacting the formaldehyde and cyanamide at an elevated temperature in the presence as catalyst of an ammonium salt which, is ammonium dihydrogen phosphate, diammonium hydrogen phosphate, triammonium phosphate, diammonium sulphate, diammonium sulphite, ammonium sulphamate or a mixture thereof. The textile material may be impregnated with an aqueous solution containing cyanamide, formaldehyde and the ammonium salt squeezed to a wet pick-up of 60-130% by weight, dried and cured at an elevated temperature or alternatively the textile material may be impregnated with an aqueous solution containing cyanamide and the ammonium salt or with separate solutions containing the cyanamide and ammonium salt, adjusted to a wet pick-up of 60-130% by weight, exposed to vapours of formaldehyde and dried and cured at an elevated temperature. Curing may be effected at temperature of from above 110C and up to 180C. The impregnating solution may contain 1-10% by weight of cyanamide, 2-5 molar equivalents of formaldehyde for each molar equivalent of cyanamide and 0.5- 5% by weight of the ammonium salt. Instead of formaldehyde, methanol hemiformal, methyl Formcel (Formcel is a registered Trade Mark) or ,paraformaldehyde may be used.

Title: Improvement in thread-cutting mechanisms for sewing machines
IPC: D05B65/00
Filed: 1946-05-13
Abstract: 611,879. Sewing-machines. SINGER MANUFACTURING CO. May 13, 1946. No. 14347. Convention date, Aug. 21, 1945. [Class 112] Thread - cutters and thread-end holders. - The needle-thread of a buttonhole sewing-machine is trimmed and held when the work-clamp is opened. and the bobbin-thread is also trimmed at the same time; the needle-thread end at the beginning of the buttonhole is retrimmed to a shorter length during the formation of the buttonhole. Both needlethread trimming operations are produced by spring-action when a pushrod is released, the resetting of the rod for the latter operation being gradual and that for the trimming at the end of sewing being rapid so that it can be delayed until the work-clamp is approaching its initial position without risk of the blades fouling the needle. The timing of the resetting and the retrimming is adjustable according to the length of the buttonhole. The means for trimming the bobbin-thread is described in Specification 611,877. Trimming needle-thread.-A vertical rock-shaft 43, Fig. 2, actuated by a pushrod 49 which is spring-biassed to the right, carries a trimming blade 38 to cut the needle-thread against a member 46, Fig. 5, carried by the work-clamp, and a nipping blade 39 to hold the end of the thread against the underside of the upper plate 11 of the work-clamp. A cam 68, adjustably secured to the feed-cam shaft by engagement of a pin with one of a series of holes 71 in a disc on the shaft, gradually moves the push-rod 49 to the left during the sewing of the first side of the buttonhole, by means of a follower lever 63, link 62, and lever 57 engaging a member 61 on the push-rod, to open the blades 38, 39, which are then closed by the sudden drop of the cam surface to shorten the thread-end shown in Fig. 5. As the cam rotates further, a projection 75 on another part of it engages the nose 76 of a lever 77 which gives another lever 81 a sharp movement to carry the push-rod 49 far enough to the left to be held by a latch 83 engaging a notch 88 in a collar on the rod. This latch is released by a cam element 93 on a sliding member 92 actuated by depression of the treadle which opens the clamp to sever the needle thread and hold its end. Specification 378,790 also is referred to.

Patent GB-645233-A (GB)
Title: Recovery of maleic or phthalic anhydride from process gases
IPC: C07C51/573
Filed: 1948-06-02
Abstract: Maleic or phthalic anhydrides are recovered from a wet process gas mixture by absorbing the anhydride on activated carbon or silica gel at a temperature between that at which the said adsorbent adsorbs a maximum of 2 per cent by weight of water and a temperature of 130 DEG C., and then removing the anhydride from the adsorbent.  The temperature minimum is calculated from the mol-fraction of water in the gas; for activated carbon it is that at which the relative humidity of the gas is 30 per cent.  When silica gel is employed the corresponding relative humidity is 10 per cent and the minimum adsorption temperature is not less than 90 DEG  C.  Adsorbed anhydride is removed by heating at 140-280 DEG  C., if desired in conjunction with a partial vacuum or a current of inert gas or vapours, e.g. of ketones; or the anhydride may be displaced by condensing a high B.P. liquid, e.g. diphenyl oxide, on to the adsorbent.  Alternatively the adsorbent may be extracted with a solvent.  In the examples, maleic anhydride is recovered from various gas streams with activated carbon or silica gel, and phthalic anhydride is recovered from the gas mixture resulting from a naphthalene oxidation, using activated carbon as the adsorbent.

Title: Improvements relating to the compression of pulverulent material prior to filling containers therewith
IPC: B65B1/18
Filed: 1954-05-20
Abstract: 781,375. Packaging pulverulent materials. ST. REGIS PAPER CO. May 20, 1954 [May 21, 1953], No. 14871/54. Class 94(1). [Also in Group XXX] Pulverulent material is compressed before being fed into containers by directing a stream of it through a compression zone of extended length, controlling the depth of the stream and vibrating it so as to assist in the production of the desired compression and advancing it at a rate regulatable independently of its vibration to a filling machine. In the construction shown in Fig. 1, the material flows down a shoot 2 inclined at an angle greater than its angle of repose to a filling machine 6. Distributers 1, 1a at the ends of the shoot are connected to it by resilient couplings 7. The shoot is vibrated by vibrators 3. In another construction, Fig. 2, material passes from a hopper 8 into a casing 2b provided with vibrators 3. A screw 10 conveys the material to the filling machine 6. Air escapes through a filter 13. In a further construction, Fig. 4, material is transported through the casing 2b by push plates 11 mounted on an endless belt 12.

Abstract: 277,737. Rickets, W. J., and Paddle, L. H. June 18, 1926. Diaphragms; microphones. - A composite diaphragm for a telephone transmitter comprises a flexible layer or layers of rubber or rubber - coated sheet material so associated with a layer or layers of reticulated or perforated material of a stiffer nature that the portions of the flexible material not in contact with the perforated or reticulated member or members are capable of being influenced independently by sound waves, the complete diaphragm being also capable of vibration as a whole. The reticulated member, when used, is preferably formed of wire gauze or net or of a stiffened textile fabric of an openwork character. The perforated member is preferably formed of sheet metal, celluloid, mica or the like.
