Preferably an auxiliary drum 42 is stepped for every revolution, or fraction thereof, of the main drum 12, and has axial grooves 43 which may receive plates 44 (Fig. 10 and Fig. 6, not shown) for holding follower 31 out of engagement with some of the comb-like members. As shown six main drums 12, with respective followers 31 and auxiliary drums 42, are provided. The shaft 1 is rotated by suitable clockwork at one revolution in ten minutes, and cam 12 has ten radial steps 21 connected by ten axial steps 20 such that follower 22 is lifted and then stepped axially every minute. Follower 22 is on an arm 23 secured by a cross-piece 25 to another arm 24 and fixed to an axially slidable shaft 27 such that arms 29 carrying followers 31 are also lifted and stepped axially every minute, the axial displacement corresponding to the spacing of teeth on the comb-like members in grooves 13. A gear 2 on the lower end of shaft 1 with Geneva mechanism 5, 6, 7 arid gears 9, 10 rotate drums 12 and their hollow shaft 11 once for every 144 revolutions of shaft 1. The drums 12 thus rotate once in 24 hours. Cam 33 acting on pawl 36 thus steps the auxiliary drums 42 twice per day and, since there are 14 pins 40 and slots 43, the auxiliary drums rotate once a week. The followers 31 comprise slidable rods which actuate microswitches 32 when they encounter teeth 15 (as in Fig. 10). Arms 29 are connected to cross-piece 25 by springs 30 such that if a plate 44 on drum 42 is positioned under extension 45 of an arm 29 the follower 31 cannot sense the comb teeth and the associated switch 32 cannot be actuated during the corresponding half-day period.

Title: Improvements in or relating to strainers for liquids flowing under pressure
IPC: B01D29/15
Filed: 1963-12-24
Abstract: 1,037,837. Self-cleaning liquid filter. G.F.G. CLOUGH. Dec. 21,1964 [Dec. 24, 1963], No. 51026/63. Heading B1D. Liquid flows from inlet 12A through a movable strainer element 47A to outlet 14A, and a lower sludge outlet 4A is normally kept closed by a valve member 51A by the pressure on the valve member and by the attraction between a magnet 33A on the top of the valve rod 32A and a fixed iron attraction member 58, a spring 64 urging element 47A downwards on rod 32A, and a valve disc 66 being movable to close the openings 53A in element 47A in which filter medium is located. When filter medium blockage causes a rise in pressure below element 47A, the element is lifted and spring 64 compressed until valve member 51A is unseated, in a sudden action as magnet 33A lifts. Accumulated solids are ejected from outlet 4A, and the resulting loss in pressure below element 47A causes backwashing of the filter medium until disc 66 descends on to element 47A and cuts off the backwashing flow and forces element 47A downwards causing valve member 51A to re-seat. With sludge outlet 4A closed, rising pressure lifts disc 66 and normal flow is resumed. The filter medium is a gauze annulus between plates 47A, 59 which have corresponding holes 53A, 60. The liquid enters chamber 1A tangentially to effect heavy particle separation. In another embodiment (Figs. 1-4, not shown) the strainer element carries a cylindrical straining basket over each of its apertures, and loss of liquid when the sludge outlet is open is limited by an inlet restriction. Backwashing is enhanced by a liquid reservoir, incorporating a spring-loaded piston, above the strainer element, and the open time of the sludge outlet valve is increased by a second fixed attraction member which the magnet engages when lifted clear of the lower attraction member. The magnet also acts as the piston of a dashpot. The valve rod may be extended above the magnet and connect to an external dashpot, and an air vessel may replace the liquid reservoir. Movement of the magnet, the valve rod or the strainer element may actuate an adjacent or remote indicator or switch.

Abstract: 1,204,007. Friction clutches. BORG WARNER CORP. 13 Nov., 1967 [1 Dec., 1966], No. 51564/67. Heading F2C. A multiplate friction clutch 18 between an input shaft 14 and an output element 16 is engaged by torque responsive screw and nut means 22 when a winding 54 is energized to engage a pilot electromagnetic clutch 72, 80 between the torque responsive means 22 and the output element 16. In Fig. 1 the torque responsive means comprises screws 98 in a carrier 82, 84 fast with the armature 80 of the pilot clutch. Nuts 92 surrounding the screws 98 have external teeth 100 meshing splines 30 on a hub 28 fast with the input shaft. Recirculating balls 96 are interposed between grooves in the screws 98 and nuts 92. When the winding 54 of the electromagnet is energized to engage the clutch a polepiece 63 moves right to engage a friction ring 72 with the armature 80 whereupon relative rotation between the carrier 82, 84 and hub 28 causes the nuts 92 to rotate on the screws 98 and thus exert an axial engaging force on a presser plate 48 of the multiplate clutch 18. Waved springs 52 separate the clutch plates 34, 36 during disengagement. The clutch is continuously lubricated through ducts 114a, 116, 120. In Fig. 3 the torque responsive means comprises balls 142 carried by a nut 146 rotatably fast with the armature 80a and the balls 142 engage helical grooves 140 in a screw 136 fast with the input shaft 14. When the winding 54 of the electromagnet is energized to engage the clutch, the armature 80a moves left relative to the nut 146 to engage a polepiece 63a fast with the output element 16. Thereafter relative rotation between the screw 136 and nut 146 produces an axial force on a presser plate 134 to engage the clutch against the bias of release springs 128. Spring pressed plungers 156 engage recesses in the presser plate 134 during clutch disengagement to prevent relative rotation between the screw and nut. The plungers are withdrawn from the recesses when the armature moves left. A spring 182 biases the armature to the right. In Fig. 7a (not shown), a housing sleeve connecting the polepiece to the output element encloses the clutch and the driven discs are splined to the housing sleeve.
