Liquid introduced by pump 16 is treated by upward flow from inlet 18, through zone 22 of a bed of granular material 12, to outlet 24 from which a portion of treated liquid is recycled by pump 36 to above the upper surface 42 of the bed, whence it flows down through zone 44, creating downward pressure which stabilises zone 22, and periodically pump 16 is shut off, valve 70 closed: and pump 36 builds up pressure within the bed to force some of the bed material down through normally closed valve 20. In Fig. 2 this discharge of material is aided by vacuum created in chamber 72 by pump 74, valve 26 being closed. Or valve 26 could remain open, in which case the vacuum effects the discharge largely by itself. Subsequently, either before or after restoring normal flow of liquid, valve 54 is opened to allow additional bed material; 'under liquid 56 to enter the containment vessel 10. The discharge may be initiated by a pressure switch 57 and thereafter controlled by timer 58, if bed 12 is a filter bed, and valve 54 is controlled to restore the bed to a predetermined level by sensor 68. Or bed discharge and replacement may be controlled wholly by a timer, by a treated liquid analyser or by a liquid meter after a given amount of liquid has passed. The apparatus may soften, treat or filter water by passage through a bed of ion exchange resins, sand or active carbon, or may purify sewage or food processing waste by passage through granular or powdered coal. As shown, the liquid effluent from zone 44 passes through outlet 24, but another outlet, above 24, could be provided.

Title: Method and apparatus for the manufacture of wood screws
IPC: B21H3/04
Filed: 1962-12-31
Abstract: 951,375. Making screws; rolling; lathe details. ALTENLOH, BRINCK & CO. Dec. 31, 1962 [Dec. 30, 1961], No. 49167/62. Headings B3A, B3M and B3T. A method of manufacturing wood screws from prefabricated blanks includes the steps of rolling a shank portion of a blank between thread rollers, and tapering the end of the blank by a cutting tool. Thread rollers 3 and 4 are driven through gears 6, 7, 9, 10 and 12, and a sliding coupling 14, by a motor 1, one of the rollers 3 being movable by an hydraulic cylinder 16 to alter the gap between the rollers. The same motor drives through gearing 11 to rotate cams on a shaft 5 to control the movement of a sliding table 23 on which is mounted a cutting head 20. When a shank portion of a blank has been rolled between the rollers 3 and 4, the head 20 approaches the screw end in recesses 19 and cuts a thread on the end. Axial movement of the table 23 and hence the head 20, relative to the blank is controlled by a lever 26 actuated by a cam 25, while transverse relative movement is controlled by a cam 30, the cam profiles determining the final profile of the screw end. Screws 34 and 35 permit adjustment of the head 20. The head, which has carbide tipped cutters 27 or external cutters, Fig. 4 (not shown), is driven by a motor 22. Cams 15, 17, 21 and 36 control the feed of the screw blanks, the transverse movement of the roller 3, and the ejection of the finished screw. The motor 1 can be controlled so that the speed of the rollers 3 and 4 is slower during cutting than during rolling.
