Title: Apparatus for treating sewage and other liquids containing debris
IPC: E02B5/08
Filed: 1975-10-23
Abstract: 1517284 Bar screen WILLIAM E FARRER Ltd 23 Oct 1975 [21 Sept 1974] 41227/74 Heading B1D A bar screen in a sewage duct comprises spaced bars 11 mounted for rotation about their respective axes. The rotation assists paper and rags to pass through the screen so that no cleaning rake is needed, the screen stopping only rigid solids likely to damage downstream plant. Bars 11 may be cylindrical or ribbed or square or rectangular in section and may be vertical or inclined at 30‹ to vertical with their upper ends downstream. Bars can be rotated intermittently or continuously, by hand or electric motor or a hydraulic motor 13. Bars may all rotate in one direction or alternate bars may rotate in opposite directions. Fig. 2 (not shown) illustrates a hydraulic circuit including a valve (22) which periodically reverses the flow through motor 13 to reverse the rotation of the bars. As shown the bars are drivably linked by belts 15, or a chain drive could be used. Bars are mounted in bearings at the top and at their lower ends or part way down.

The teat rests on a ledge 22 encircling the mouth of the bottle in the inoperative position and is moved to the operative position by applying pressure to the hood, the ledge then preventing the teat being pulled off during feeding. The hood 30 is sealed to the wall 27 of the bottle by adhesive 40 and after removal of the adhesive 40, the teat is forced into its operative position. In a further embodiment, Fig. 7 (not shown), channels (315) are provided in the uper portion of a cylindrical inner face (316) of a teat (310) and the teat (310) is moved from an inoperative position to an operative position by rotation of a hood (335) until the channels align with orifices (323) in the mouth (321) of a feeding bottle (320). In another embodiment, Fig. 6 (not shown), a teat (210) rests on an outer flange (265) of an intermeidate piece (260) having orifices (266) in a cylindrical portion (262). The cylindrical portion (262) is slidable within the open mouth (221) of a feeding bottle (220) the orifices (266) being covered by the cylindrical wall of the mouth in the inoperative position (Fig. 6c). In each embodiment the teat may be filled with powdered milk and the feeding bottle with water so that when the teat is in the operative position they may be mixed.

[Also in Division F2] Flexible hose is made by helically winding, on a former consisting of a plurality of rows of rollers 3 mounted on a fixed shaft 2 such that each roller ia inclined tangentially with respect to the axis of the shaft 2, a hose forming strip D extruded in a semi-molten state from an extruder C and comprising a matrix 10 of soft synthetic resin material containing a reinforcing core 11 of synthetic material having a higher strength and hardness than the matrix material and a string member 12 having a lower elongation characteristic than the reinforcing core, at least one row of rollers being driven such that the strip is wound helically in close contact with the rollers and with adjacent convolutions whereby adjacent margins of the strip D are fused to form a flexible reinforced base. In the embodiment of Figs. 1-3, all the rollers are driven, the rollers at one end of each row being coupled by universally jointed shafts 5 to gears in a housing 1 which mesh with a central gear whose shaft 9 is coaxial with the shaft 2 and is driven by a motor, while the other rollers in each row are coupled to each other by further universally jointed shafts journalled in brackets on the shaft 12. In a modification (Figs. 4 and 5, not shown) only one row of rollers is driven, the remaining rollers being independently journalled in the brackets on shaft 2. The extruder C is of known type in that it comprises opposed inlets 14, 15 for matrix material and reinforcing core material, respectively. In order to introduce the string member 12, a bore 17 is provided coaxial with the outlet orifice 16, the bore passing centrally through an insert which is shaped to direct the two streams of plastic material into the desired relative positions one within the other. By applying tension to the string member, the latter is maintained within the stream of reinforcing core material. A second extruder F may be provided to extrude a further layer E of abrasion resistant synthetic resin to form an outer layer over the layer formed by the strip D, the arrangement being such that the convolutions of the layer E are staggered with respect to those of the strip D. Alternatively, the positions of the two extruders along the length of shaft 2 may be reversed so that the layer E is formed within the layer formed by the strip D.

Abstract: 921,816. Moulding foamed elastomers. DUNLOP RUBBER CO. Ltd. Dec. 21, 1959 [Dec. 22, 1958], No. 43262/59. Class 87(2). A cover for a mould for use with expanding elastomer foams, such as the polyurethanes, has longer and shorter cores depending from its undersurface at spaced intervals, the longer cores alternating with the shorter cores and at least some of the cores being pointed at their lower end. The cores are disposed at the intersections of parallel lines crossing other parallel lines, the lines intersecting at right-angles or at angles of 60 degrees. Figs. 9 and 11 show two such arrangements of cores, the cores being of three different lengths as shown in Fig. 10 which is a vertical section on line 10-10 of Fig. 9. When moulds incorporating such covers are used, the space between the longer or longest cores is restricted only slightly as the level of the foam rises relative to the cores and as it rises to the next shorter cores the space is again restricted only slightly more so that at no level is there any abrupt restriction. Accordingly there is a much reduced tendency for densification of the foaming elastomer to arise.
