Abstract: 479,639. Strainers. JONES & ATTWOOD, Ltd. Feb. 20, 1937, No. 5138. Convention date, Feb. 21, 1936. [Class 46] Solid matter intercepted by a slotted straining wall is sheared off and comminuted by a cutter bar held against the straining wall and having movement relatively thereto without entering the slots of the wall. The apparatus shown comprises a cylindrical strainer A comprising longitudinal ribs 29 connected by arcuate bars 30 which form intermediate circumferential straining slots. The ribs 29 are flush with the outer surfaces of the bars and both ribs and bars taper inwardly. The strainer is supported by webs 24 from a hub 23 fixed on a shaft 21 rotated by an electric motor 20. The strainer is arranged in a container 10, to which the sewage or other liquid under treatment is supplied, and over an aperture 16 in the base through which the strained liquid is discharged. The liquid is prevented from entering at the upper end of the strainer by an annular cover 34, which is continued upward by a cylinder 41, so that solid matter cannot settle on the cover. A pipe 36 bolted to the cover 34 surrounds the shaft 21. The inwardly tapering ribs 29 form cutting edges at the end of the slots which as the strainer rotates co-operate with the edge of a cutting bar 48 to comminute the matter intercepted by and projecting from the slots in the strainer. The bar 48 is fixed to an arm 45 suspended from the cover 34 and abutting against a fixed member 49 at the lower end. The edge of the bar 48 is notched and the edges of the notches co-operate with the cutting edges of inclined teeth 50 fixed in staggered series on the outer surfaces of the ribs 29.

In apparatus for supplying liquid fuel to a compression ignition internal combustion engine comprising a shuttle piston 17 metering the supply of fuel to injection plungers 12 feeding fuel to the engine and a cylindrical stop member 28 the portion 27 of which determines the maximum outward movement of the shuttle in its cylinder, the position of the stop member is controlled by means responsive to the pressure of air entering the inlet manifold of the engine. The shuttle 17 is moved inwardly and outwardly in cylinder 16 by fuel supplied by a feed pump 22 via grooves in the distributer 11 and passages in the pump body 10 and the outward movement is controlled by a throttle (42, Fig. 2, not shown), in the passages to the inner end of the cylinder. The stop member 28 is moved against the bias of spring 29 by a diaphragm 34 acting through a rod 31 and a conical member 30. The diaphragm housing 32, 35 communicates via a union 37 with the inlet of the inlet manifold of the engine, which is pressurized by a supercharger, and the opposite side of the diaphragm is subject to atmospheric pressure via holes in housing part 32. In a further embodiment, Figs.4 and 5 (not shown), for an unsupercharged engine the maximum outward movement of the shuttle (17) is determined by a pin (50) which is acted on by the end plate of a partially evacuated bellows (58), via a plunger (48) and rod (53). The bellows is mounted in a housing (54, 56) which communicates with the atmosphere through holes (61).

Rotary filters. - In a vacuum filter of the type comprising a drum with peripheral chambers 13, the chambers 13 extend beyond the end plates 26, 27 of the drum and radial tubes 23, 24 are provided outside the end plates at either end of each chamber, the chambers being thus connected to two central valve members 18, 22, one of which serves for the discharge of strong filtrate and the other for the discharge of weak filtrate or wash liquor. The drum 1, Fig. 1, rotates on a stationary shaft 2 the central part of which may be solid or hollow and provided with a central plug 3. The ends of the shaft are hollow and pass outward through the walls of the trough 28 to which the material under treatment is supplied, and they are connected to suction pipes 33, 34 respectively. An aperture 20 on the lower side of the shaft puts the chambers which are submerged in communication with the suction pipe 33 for the strong filtrate, and a similar aperture 21 at the other end connects the uppermost chambers with the suction pipe 34 for the weak filtrate. Fig. 3 shows an arrangement in which a conical sleeve 41, which can be adjusted longitudinally to take up wear, is interposed between the valve member 18 and the shaft 2. In the alternative arrangement shown in Fig. 5, the valve member 47 is formed as a boss on the end 26 of the drum, the central shaft is hollow only at the ends and has coned portions 52<1> with apertures 53 within the valve members.
