Title: Filtering liquids
IPC: B01D24/00
Filed: 1971-09-01
Abstract: 1359225 Automatic washing of upward flow sand filters F M C CORP 1 Sept 1971 [3 Sept 1970 19 Aug 1971] 40819/71 Heading BID In filtering, e.g. sewage, filtration and washing of the filter both occur upwardly, at different rates, through a "sand bed" filter so that fluidisation occurs only during washing. As shown in Fig. 7 raw feed is pumped (by filter pump 26) (or fed by gravity) 'from sewage treatment plant 64 and reservoir 66 and passes to graded filter bed 20. Filtrate passes via a trough 21 to the first compartment of an intermediary chamber 35 and exits via pipe 39. Wash liquid (which may be raw feed) is pumped at a higher rate by filter pump 27 whereupon the bed is fluidised, optionally assisted by compressed air. Wash liquid then passes via the trough 21, the second compartment of the chamber 35 and wash liquid collection chamber 15 whereunon it is returned to the sewage treatment plant 64. The wash cycle is automatically initiated either in response to pressure build up or by a timer. In one form Fig. 15 (not shown) the apparatus includes both a timer and a pressure responsive valve as shown at 34. The pumps 26, 27 may operate together or independently, or a single two rate pump or a series of pumps may be used. In a modification the trough is height adjustable at its end futhermost from the intermediary chamber which is provided with both filtrate and wash liquid discharge pipes (94, 95) Fig. 11 (not shown), one or both of which may discharge to a respective tank 96, Fig. 14. The tank has a chamber 98 fed at a variable rate with raw feed from inlet 102. Filtrate issuing from pipe 95 discharges into the chamber 98 until float 107 ascends to tilt trough 110, whereupon filtrate discharges at 114. The wash liquid collection chamber 15, Fig. 7, may be replaced by such an arrangement connected to the second compartment of the intermediary chamber 35. Filter inlet pipe 24 may be replaced by a number of pipes. The filter material may be graded gravel and sand, activated carbon, anthracite, ion exchange resin garnet granules or synthetic or natural zeolites. It may be biochemically reactive and chemicals may be added.

Abstract: 941,155. Hatch covers. PNEUMO DYNAMICS CORPORATION. Nov. 15, 1961 [Nov. 17, 1960], No. 40935/61. Heading B7S. [Also in Division E2] A hatch cover comprises a plurality of panels 12, 14, 19 and 21 which are hinged to each other at 16, 18 and 22 and to the deck at 13 and which may be moved from the extended position, shown in Fig. 1, to a stowed position, shown in Fig. 3, by hydraulic motors, not shown. The cover further comprises hydraulic jacks 18 and 26 and control means to move the jacks 18 and 26 before the hydraulic motors are effective to move the panels from the extended position. The jack 18 includes rollers 44 and 46, which move on coaming tracks 29, and which are supported on links pivoted to the jack body and connected to an hydraulic piston and cylinder which rotates them above their pivots to raise or lower the panels. The jack 24 similarly includes a roller 28 supported by a link 26 which is rotated by an hydraulic motor 31. The roller supporting links of both jack assemblies abut over centred stops in the stowed position so that the weight of the panels will maintain them in the jacked position. The panels are moved by a plurality of hydraulic motors 51, Fig. 4, which co-operate with the hinge, e.g. 16 to move the panel, e.g., 12 through 180 degrees by means of the links 57 and 60. The Specification describes an hydraulic control circuit including a single three position four-way valve to control the flow from a pump to the double-acting moving and jack motors and back to a reservoir through a drain. The lines from the moving motors to drain are provided with rate control orifices which operate when the cover is closing to ensure that one pair moves to the extended position slower than another. The lines to the jacking motors include a spring loaded shut-off valve which provides pressure liquid to the jacks onlywhen the cover is in the extended position. The jacking motors and moving motors are connected in the same hydraulic circuit but are sized so that the former operate at a lower pressure so that the cover is fully jacked before it starts to move and clears any water tight seals which may be provided. The actuating system may be pneumatic.
