IPC: C08L1/08
Filed: 1929-08-01
Abstract: 317,443. British Celanese, Ltd., (Assignees of Moss, W. H.). Aug. 16, 1928, [Convention date]. Compositions containing cellulose derivatives. -Plastic compositions containing organic cellulose derivatives are rendered more plastic by the addition of a limited amount of water, for example, between 1 per cent and 6 per cent by weight. The composition may be in the form of powder, sheets, blocks &c. The invention is particularly applicable to the manufacture of unsplinterable compound glass sheets comprising celluloid-like sheets cemented between sheets of glass, and enables lower pressures to be used. The celluloid-like sheets may be soaked until the desired amount of water is taken up, and the soaking bath may, contain solvents or partial solvents such as ethyl alcohol, ethyl lactats and a softener such as triacetin and inorganic salts. If gelatin or glue is employed as the adhesive, the water in the celluloid-like sheet improves the adhesion to the glass sheets. The composition may contain cellulose esters such as cellulose acetate, formate, propionate or butyrate, or cellulose ethers such as ethyl, methyl or benzylcellulose.

Abstract: 481,291. Changing signs. TELEFONAKTIEBOLAGET L. M. ERICSSON, and SCHEWELOV, I. Sept. 8, 1936, No. 24501. [Class 3 (i)] A plurality of flexible display panels A, B, C attached by one edge uniformly around a drum or prism e are selectively brought to view by first rotating the drum in the winding-on direction till the free end of the panel reaches a requisite position, and then reversing the direction of rotation of the drum to unwind the panels, the required panel then overlying the others. Each panel is furnished with a metal or other heavy rod a<1>, b<1> at its free end, this rod both serving to tension the hanging panel and for riding on drum flanges d, g to act as switch operating means for controlling the operating motor. Fig. 4 shows switch members h, j whereby at the passage of each rod a<1>, b<1> thereunder a contact is broken, thus sending impulses to a step-by-step switch, Fig. 7, which has, in addition to positions 1<1>-10<1> corresponding to each panel, a position 11<1> for controlling the turning-over of the leaves and a position of rest 12<1>. The switch disc p is turned by a magnet OL receiving impulses from a supervising device, such as a telephone dial type of apparatus. A similar switch at the other end of the drum is actuated by only one of the rods a<1>, b<1>, a collar being provided thereon to increase its effective diameter. This switch shifts the connections of the motor field to reverse the motor and unwind the display panel. The drum e carries on one flange d an S-shaped flat plate t, Figs. 10 and 11, turnable about the drum axis through a small angle under the influence of a spiral spring. The plate t takes behind a rod a<1>, b<1> and follows same during unwinding till it strikes an abutment x. On re-winding, the plate t is taken back by the first rod a<1>, b<1> till its end u strikes a projection y and is thereby deflected out to allow the rod a<1>, b<1> to pass by and drop on the rear side of the drum. An abutment w positions the rods a<1>, b<1> and the plate t snaps past to engage the next rod a', b<1>. The motor is stopped by a contact c being broken by the weight of the lowermost rod a<1>, b<1> contacting therewith, and is re-started by a push-button, the completion of the restoration of the panels to their starting position being signalled by a lamp in the supervising device. Several displays can be interconnected, and be restored by a single push-button which is momentarily depressed.
