Abstract: 203,162. Hurrell, G. C. Aug. 16, 1922. Filters having sheet filtering-materials.-In pressure filtars of the type in which the liquid to be filtered is forced into a vessel provided with surfaces for arresting solids and ducts for removing the filtered liquid, the liquid being forced into the filter until the desired thickness of cake is formed, and the cake then being washed and dried before removal, the filter comprises a cylindrical shell 1, Figs. 1 and 2, and an inner pervious tube 2. A plug or valve for opening or closing one end of the cylinder is provided and valves are fitted for the admission of liquid, wash-water, and compressed air. In the form shown in Fig. 1, the liquid is admitted through the pipe 6 and inlet 3 until the cake 12 is of the desired thickness, the filtrate being removed by the pipe 14. Compressed air is first admitted by the pipe 7, then wash-water through the pipe 8, and the cake is finally dried by a further supply of compressed air. The sleeve 16 is now rotated to open ports 4, compressed air is admitted to the interior of the tube 2 by the pipe 15, and the cake is blown off and removed. In the form shown in Fig. 2, the filter is adapted to function automatically, the cake being removed at intervals by a worm 19. In this construction, an enlargement 22 of the tube 2 is provided with a number of valve chests, of which two, 24, 25 are shown. A sleeve 17 is rotatably mounted in the port 22, and is provided with a port 26 adapted to establish communication between the valve chests and the ingress tube 3 for the admission in turn of liquid. wash-water, and compressed-air. The sleeve 17 is driven from a shaft 27, a pair of cams 29 on which close the plug 16 at the commencement of each operation, whilst a cam 30 actuates the belt shift bar 31 to set in motion the worm 19. When the worm 19 is operated, an opening 15 registers with a port in the valve chast 23, which admits compressed air to dislodge the cake. The filtrate is removed by a pipe 14. The worm 19 may be dispensed with. Specification 174,116 is referred to.

Title: Method of cold-stretching orientable films
IPC: B29C55/06
Filed: 1962-06-12
Abstract: 1,006,675. Stretching films longitudinally. O. B. RUSMUSSEN. June 12, 1962, No. 22424/62. Drawings to Specification. Heading B5B. A web of film of crystalline orientable synthetic organic polymeric material is continuously cold-stretched in the longitudinal direction and before being passed through the stretching zone is so pleated by being passed through a mechanical pleating device that the " apparent width " of the film is reduced by the formation of pleats to substantially the " surface width " of the film after it has been coldstretched. The " apparent width " of the film is defined as the width obtained by measuring the distance in a straight line between the edges of the film, and the surface width of the film, as the width as measured along the actual surface of the film, following the contours formed by the pleats of the film. The pleats formed initially are preferably converted into narrower pleats, before the film is longitudinally stretched, by repeatedly passing transversely across the film a pressure point while exerting sufficient pressure to straighten out each pleat as the point passes over that pleat, the narrower pleats spontaneously forming as the pressure point passes on across the film.
