Steam chests 1, 2 hinged at 4 are secured in the closed position by clamps 5 consisting of girder brackets 7 hinged to lugs 6 on the chest 1, and carrying at their outer ends 7a lever operated cams 11 pivoted at 10, and co-acting with lugs 8 on the chest 2. In the inoperative position the clamps 5 are swung out until a face 7c bears against the chest 1, in which position projections 17 lie in the path of lugs 16 on a ring 14 which operates the valve 15 for supplying pressure to the tyre. Mounted on the ring 14 is a plate 14c with a cam slot 14b engaging the actuating lever 15a of the valve 15. When all the clamps 5 are closed the ring 14 can be rotated into the position shown to open the valve and admit pressure fluid to the interior of the tyre by the pipe 15c. The lugs 16 now prevent the clamps from being released; to do this, the lugs 16 must be rotated clear of the clamps, the valve 15 being opened to exhaust in this operation. In a modification, the valve 15 is operated by a plunger, which is depressed by an attachment on the cam lever 9, on closing one of the clamps 5, and held by a spring catch. The catch has to be opened, thereby opening the valve 15 to the atmosphere, before the clamp can be removed from the mould. A ring similar to the ring 14 may be provided to ensure that the valve-actuating clamp is the last to be closed, and the first to be opened.

Filed: 1954-03-18
Abstract: 756,475. Optical systems. MORROS, B. M. March 18, 1954 [Sept. 3, 1953], No. 7974/54. Class 97 (1). A system for apparatus having a single objective lens for photographing or projecting left and right eye stereoscopic images which are turned through 90 degrees in relation to the object and lie base to base on the photographic carrier, comprises two sets of three reflecting prisms each, the sets being mounted symmetrically to each other in relation to the axis of the lens and the reflecting surfaces of the entrance and/or exit prism of each set being arranged at such an angle to the path of rays that they totally reflect the rays pertaining to one image and allow the rays pertaining to the other image of pass through whereby separations of the images is achieved. Fig. 2 shows one set of prisms according to the invention, the angle a of the prims 15 and 17 being chosen to ensure the desired result. The prisms 15 and 17 may be replaced by a rhombic prism having two parallel surfaces at each of which the beam is reflected before emerging from the prism. Fig. 1 illustrates the principal of the invention. Light from a point 12 of the right image 3 will be incident on the surface 6b of the right-hand prism at an angle # less than the critical angle and so will be substantially transmitted by that surface and lost. However light from the same point 12 will be incident on the surface 5b of the left-hand prism at an angle y greater than the critical angle and so will be totally reflected by that surface and by the surface 5a to pass to the projection screen. The converse process applies to light from the left image 2. Similar conditions hold in photography.

Title: Improvements in the manufacture of viscose products
IPC: D01F2/06
Filed: 1929-03-14
Abstract: 307,848. I. G. Farbenindustrie Akt.- Ges. March 14, 1928, [Convention date]. Cellulose xanthates; varying physical properties of formed articles.-Heavy metal compounds are removed from viscose products, to which they would otherwise give a dark, spotty, or streaky appearance, by treating them with oxalic acid or aliphatic oxy-acids, such as tartaric or citric acids, which form easily soluble chemical compounds with these metals, or with salts of these acids. The viscose products may be treated during the washing operation following complete coagulation of the viscose, or at any of the subsequent stages in their manufacture; thus, for example, the products may be treated before or after desulphurizing or the organic acid or its salt may be added to the desulphurizing or other treatment bath. Artificial silk may be treated in any form, e.g. in hanks or on spools; thus, the silk on the spools may be treated at any stage, e.g. washing, desulphurizing, souring, bleaching, or soaping, by the suction process. The process differs from the usual operation for improving artificial silk to give a silk-like, crackling feel, since the acid used in that process should remain in the fibre whereas in the present process, the viscose product must be carefully washed in order to remove the soluble heavy metal compounds formed during the treatment. In examples, hanks of artificial silk before, or after being desulphurized are treated with oxalic or lactic acid solutions respectively and artificial silk is washed before being desulphurized with oxalic acid solution by the suction method. Subsequent treatment is carried out according to the usual practice.
