Patent GB-519986-A (GB)
Title: Improvements in the production of crepe effects on fabrics
Filed: 1938-10-07
Abstract: 519,986. Treating textiles with liquids. EWING, H. Oct. 7, 1938, No. 29104. [Class 15 (ii)] A fabric containing warp and weft yarns of an organic derivative of cellulose or other hydrophobe film-forming substance, the weft yarns being highly twisted, is subjected to treatment with formaldehyde or other agent which is capable of hardening the warp yarns, and the sotreated fabric is subjected to the action of a crape-scouring bath whereby crape effects are obtained. The formaldehyde treatment enables pebble effects to be obtained even when the weft yarns have a twist of not more than 80 turns per inch. The formaldehyde may be applied in dilute aqueous solution, e.g., by padding and after this application, the fabric may be dried under substantially no applied tension and then scoured with hot soap solution. The fabric may be sized with gelatin or casein before the formaldehyde treatment or before scouring, or such size may be contained in the warp threads only. The formaldehyde treatment minimises shrinkage of the fabric in the warpwise direction. Instead of formaldehyde, there may be used acetaldehyde, benzaldehyde, furfural, or glyoxal. Fabrics containing yarns of cellulose acetate, propionate, or other ester or mixed ester of cellulose or ethyl, benzyl, or other ether or ether-ester of cellulose, or polyvinyl acetate or other polyvinyl ester or ether, or polyacrylic or polymethacrylic ester, may be treated. The weft yarns may be twisted in the presence of steam or hot water.

Abstract: 207,008. Hilton, J. Oct. 26, 1922. Carding - engines; feeding carding. engines; burring - - apparatus.-To effect a preliminary opening of material, such as burry wool or matted fleeces, fed to the takers-in of carding-machines, it is acted on by one, or more rollers comprising a number of toothed bars which are moved positively by cam action about their own axes as the roller rotates. The material is fed from the lattice. k, Fig. 4, by a plate l and wire-covered roller m, to a roller b comprising toothed bars e, which are moved about their axes so as to be in a suitable position to take up the material from the roller m and also in a position to deliver up the material to rollers p, p<1>, p<2>, which convey it to the licker-in o. The speed of the rollers is successively increased to assist in the opening-up operation. A grid n surround-- the lower portion of the roller b to allow the dirt &c. to escape. A plate and roller, or two fluted rollers, or two wire-covered rollers, may be cmployed to deliver or convey the material to or from the roller b, and two or more rollers b may be used in succession. The roller b is built up of end discs a, Fig. 1, with openings in which the toothed bars e rotate. Each bar has an arm g with a bowl h running in a fixed cam groove ix. To ensure correct movement of the bars, projections j<1> engage lugs on the bars at the lowest osition, and depressions j<2> are provided in the cam grooves at the highest position.

Title: Improvements in folding tops for any type of vehicle or motor boat
IPC: B60J7/12
Filed: 1920-10-19
Abstract: 152,659. Buch, M. Oct. 22, 1917, [Convention date]. Hoods.-A folding top or hood for a road vehicle or motor-boat comprises a substantially horizontal outrigger bow pivoted at the rear to a supporting standard and divided into front and rear parts connected by a downwardly broken joint, one of the parts of the bow or linkwork connected thereto being extended to the rear of the standard and shaped to form or carry a how arm. As shown in Fig. 1, the front part 5 of the bow is connected to a supporting standard 3 by the rear part 6, which is extended at 6<c> in rear of the standard and shaped to form or carry a cover-supporting bow, the part 6 being connected to the standard 3 by a fixed pivot. The standard 3 is shown pivoted to a vehicle 1 at 3<a>, and to it is pivoted at 4<a> a rear bow 4, but this arrangement may be reversed, the bow 4 being pivoted to the vehicle and the standard 3 to the bow 4. If desired, an intermediate bow 7 may be pivoted at 7a to the part 6. The part 6 is preferably connected to the bow 5 by a lock joint 6<a>. When the joint 6<a> is broken downwardly in folding, the pull of the top covering 2 upon the extension 6<c> serves to balance the front extension and enable it to be moved back from one side only into the position shown in dotted lines, and to permit the operator properly to arrange the cover material preparatory to complete folding. In a modification, a link 6<y>, Fig. 2, is connected to the standard 3 above the part 6<x> which is pivoted at 6<a> to the bow 5, the link 6Y being pivoted to the bow 5 in advance of 6<a> and being connected by a link 7<y> to the top bow 7<x>. In this case, the link 6<y> is extended at 6<z> to form a cover-supporting bow. Instead of a lock-joint at 6<a>, upward movement may be prevented by a pin x on the link 6<x> acting on the link 6<y>. In another modification, a rear part at each side connects the front part of the bow to the standard, and has pivoted to it a forwardlyinclined top bow, the upper link, having the extension to the rear of the standard, being pivoted to this bow. In a form similar to that shown in Fig. 2, the top of the standard carries a bow, and the standard and rear bow are pivoted to the vehicle at the same point. The Specification as open to inspection under Sect. 91 (3) (a) comprises also another form, in which links 6, 9, Fig. 5 (Cancelled), are pivoted to the standard 3 at 6<a>, 9<b>, the link 9 being provided with the rear extension 9<x> and being pivoted to the front bow 5 at 5<a>. A link 8 connects the link 6 and the top bow 7 and is pivoted to the link 9 at 9<a>. In this form, metal bow arms 4, 5, 7, 9<x> are shown provided with sockets for wooden bows W, W, W<1>, W<2> respectively, but when allsteel constructions are used, the bows are made in one with -the arms. It is also stated that the rear bow may be omitted for use on two-seated or short cars, the main standard being inclined to a suitable position. This subject-matter does not appear in the Specification as accepted.
