Title: Improvements in and relating to fabrics and a method of manufacturing said improved fabrics particularly applicable to the manufacture of ring packings for glands
IPC: B29D30/38
Filed: 1921-02-08
Abstract: 176,745. Trist, A. R. Feb. 8, 1921. Hose and flexible pipes.-A fabric, for use in superimposed layers for hose piping &c., is composed of interwoven warp and weft threads, and auxiliary threads overlaid on, and at an angle to the warp and weft threads. The threads are impregnated with an agglutinant, and the whole rolled into a smooth sheet by the application of heat and pressure. The material is cut on the bias, thus enabling the auxiliary threads to assist the warp and weft threads to resist tensional stress. A method of making such material, in which the auxiliary threads are disposed at 45‹ to the warp and weft threads is illustrated in Fig. 2. Impregnated fabric d is wound on to the mandrel f with an angular pitch of 45‹, the edges of the fabric being arranged to abut. The auxiliary .impregnated thread a is wound on to the fabric at such a pitch as will produce the required spacing, and embedded thereon by rollers (not shown). The cylinder of material is now cut along the junction line h so as to produce a strip similar in dimension and shape to the original fabric d. This strip is cut on the bias as at i and k so that the auxiliary threads are at 90‹ to the cut edge.

Abstract: 692,321. Stereoscopic picture projectors. GRUBER, W. B. March 1, 1951 [March 2, 1950], No. 4966/51. Class 97 (i). Twin objectives are moved for focusing by a single control, their axes being maintained parallel during the movement and the separa. tion ot the lens axes being varied, to adjust the convergence of the projection axes, so that substantially identical superposition of the projected images is obtained independently of the screen distance. Fig. 2 shows one lens mount supporting arrangement in horizontal section taken at different levels in the regions of the two lenses. Each mount is carried on a lug 12 upstanding from a base 11 with downwardly projecting pins 46, engaging a slot 45 in the base 10, and a downwardly projecting stem 15 in a clearance hole 17 in the base. The slots 45 beneath the two objectives are oppositely inclined and the lens mounts are guided, by the pins 46, during axial focusing movements to produce the accompanying lateral movements. The slots may be straight but theoretically should have a slight curvature, the nature of which is derived in the Specification. The adjusting mechanism is shown in Fig. 3. Levers 22 are held by a connecting spring 41 with slots 23 engaged with pins 24, secured to the plate 10, and ends 38 abutting the end of the screw 37 carrying an operating knob 35 and being engaged in a screw-threaded lug 29.
