Abstract: 1,101,186. Centrifugal strainer. W. J. C. TRYTHALL. 10 Sept., 1964 [21 Oct., 1963], No. 41481/63. Heading B1D. In a centrifugal strainer comprising a basket 1 rotating about a vertical axis within a casing 4 which terminates in a lower hopper 20, the bottom 7 of the basket is lowered (as shown) to discharge dried solids from the basket into the hopper 20, and subsequently air pressure is applied to push the solids out of the hopper through outlet 21. Basket 1 is rotated by multispeed electric motor 27 through clutch 28, belt 29 and hollow drive spindle 2. Spindle 2 carries an air cylinder 9 whereby the bottom 7 is raised and lowered on the end of piston rod 8. Hopper 20 is surrounded by a compressed air reservoir 22, connected by valve 24 to a perforated pipe 25 which directs air on to the outside of perforated basket 1. Casing 4 has a peripheral gutter 14 and a valved outlet 15 to collect and discharge liquid during centrifuging, and may enclose a steam jacket 16. In use, the basket is filled, while rotating slowly, through valve 26 from an overhead hopper or from a pneumatic transport pipe. Valve 26 is closed, the valve on outlet 15 opened and the material centrifuged at high speed. The bottom 7 of the basket is then lowered, motor 27 switched to low speed and valve 24 opened, so the dried material is blown and falls into hopper 20. Outlet 15 is closed, and, as air from pipe 25 continues to blow through the perforations of basket 1 and thereby cleans them, pressure builds up in casing 4 until it blows the solid material through outlet 21. Control may be manual or automatic and linked with preceding or following processes. The machine may be used to strain the oil or fat from hot greaves. Periodic cleaning is by directing steam or solvent through pipe 25.

[Also in Division G1] In a thermostatic control valve e.g. for controlling the flow of automobile engine cooling water, a closed ended tubular sensing element 12, filled with expansible wax, is movable relative to a fixed pin 2, sealably projecting therein, and fixedly carries a cup-shaped closure 10, guided within flow aperture 7 by extensions 11, which is displaceable against spring 9 to open the aperture 7 upon rise of fluid temperature and, upon loss of expansible wax through leakage, the closure is displaced in the opposite direction by spring 9 through the aperture 7 which is thereby opened to permit fluid flow and prevent overheating. Alternatively, the element 12 may be fixed with the pin 2 displaceably carrying the closure element. In normal operation, the opening of the valve is delayed by the height of the cylindrical wall of the closure. In other embodiments, the closure comprises a cup-shaped element (21) (Figs. 4 to 6 not shown) fixed to the tubular sensing element (12), and sealingly engaged upon an annular plate (18) against a gasket (25) within an annular wall (24), whereupon the cup-shaped and plate elements (21, 18) are displaceable in contact to permit fluid flow through the aperture 7 upon a rise in temperature and, upon leakage of expansible wax, the plate element (18) is seated within aperture 7 whilst the cup-shaped element (21) is displaced in the reverse direction from engagement therewith by spring 9 to permit fluid flow between the cup-shaped and plate elements (18, 21). Malfunctioning of the valve is avoided by a locking device (Figs. 7 and 8, not shown) which comprises spreader rods (13) connected at their upper ends to the tubular] sensing element (12) and normally displaceable in contact therewith through a guide member (8) and which open out to rest upon the guide member and prevent reverse movement when the valve member (10) is pressed up through the flow aperture (7) upon leakage. In an alternative embodiment (Figs. 9 and 10, not shown), the locking device comprises locking pawls (16) suspended in a fixed bracket (3) which spring into engagement under a flange (15) on the valve member end of the tubular sensing element (12).
