Patent GB-466603-A (GB)
Title: Improvements in and relating to filters
IPC: B01D29/00
Filed: 1935-11-23
Abstract: 466,603. Filters. ZWICKY, J. Nov. 23, 1935, No. 32530. [Class 46] A cylindrical strainer 5, Figs. 1 and 2, has arranged concentrically within it a valve device comprising a casing 6 with ports 9 and a member 7, rotatable by a handle 15 outside the filter casing 1 and having two series of ports 8, 12, separated by division walls 50. For filtering, the ports 8 are brought into engagement with the ports 9, as shown in Fig. 2, and liquid from an inlet 2, passes through the ports 8, 9, and outward through the strainer and is discharged through an outlet 3. On turning the member 7 to bring the ports 12 over the ports 9, the flow through the strainer is reversed, the liquid passing through the ports 12 being directed by the walls 50 into a central tube 13 and discharged through an outlet at the bottom. At the same time liquid from the inlet 1 passing through a lower series of ports 11 to the outside of the strainer joins liquid returned through the outlet 3 to form the reverse flow through the strainer. In the arrangement shown in Figs. 6 and 7 the control valve 28 is arranged in an extension at the lower end of the filter casing 1. The normal flow is from the inlet 2 through a port 29 in the valve to the space outside the strainer 5, thence inward through the strainer to the outlet 3. For cleansing the valve 28 is turned so that liquid from the inlet 1 is directed through a byepass 27 leading to the upper end of the filter casing. Flow is then inward through the strainer 5 and the wash liquid is directed by the valve 28 to an outlet 4. In a similar arrangement, the byepass 27 is omitted, the inlet being merely cut off during cleansing. As shown in Fig. 6, the valve may be moved automatically, increase of the pressure difference through the strainer causing a piston 38 to move upward so that it closes the switch 34 of the circuit of a magnet 33, the armature 32 of which is attached to the valve stem. Fig. 8 shows a further modification in which a valve stem 42 moving vertically carries a member 40 to control the liquid from the inlet 2 and a member 45 to control the waste outlet 4. With the member 40 in the position shown on the right side of the Figure, the entering liquid passes downward through a gauze 46 and impurities fall through a funnel 47 into a protected sump 48. The liquid then rises and passes inward through the strainer 5 to the outlet 3. For cleansing by reverse flow, the stem 42 is raised to bring the member 40 into the position shown in the left hand of the Figure and to raise the member 45. Specification 373,717 is referred to.

[Also in Division B8] A method of erecting a flat blank to an open tray form having two pairs of opposite side walls, a pair of flaps 24, 25 at each end of one pair of side walls and bent at right-angles thereto and into the plane of one of the other side walls, and a marginal strip 12, 13 on each of said other side walls bent inwardly to overlap said flaps, comprises moving the blank into the path of a plunger, coating said marginal strips with adhesive during movement of the blank, pressing the blank into a folding die to erect it, and bending the marginal strips outwardly mechanically by means of bending elements projecting laterally over said plunger, retracting the plunger from the die and mechanically folding over and gluing the marginal strips to the inwardly bent flaps by means of pivotally mounted members. The leading blank from a magazine 36 is removed by a suction cup feed member 37 to a position where it can be gripped by cam operated gripping jaws 57 and moved past adhesive applying nozzles 63 fed from adhesive containers 60, 61 to a position between a plunger 59 and folding die 35. During initial movement of the plunger and blank into the die, the adhesive coated side walls 8, 9 and marginal strips 12, 13, are held back by deflecting members 87, Fig. 9. During continued movement of the plunger the deflecting members are halted by stops 89, 92, allowing the side walls 8, 9 to be completely erected, and the marginal strips are bent outwardly by deflectors 93 mounted on the plunger 59, Fig. 10. In a modification, Fig. 14 (not shown), the deflectors (193) are of triangular form and press the marginal strips 12, 13 against gripping needles on the shafts of the pivoted arms 100. Return movement of the plunger may then be effected without contacting the adhesive on the marginal strips, whereafter arms 100 are rotated through sprocket gearing to fold the glued marginal strips into the interior of the box, Fig. 11. On each side of the blank magazine there are mounted prefolding members (143), Fig. 19 (not shown), which first overfold the marginal strips about bars (144) so as to assist their subsequent inward folding by the arms 100. The outlet of each nozzle 63, Fig. 12 (not shown), is controlled by an apertured diaphragm (64) carried by a member (65) pivoted at (66) and cam-operated in the desired sequence.
