[Also in Divisions B8 and Gl] A load cell 22 comprises a valve stem 21 which is slidable through the wall of a casing 25a and has a disc 28 which can interact with a sealing surface of soft, resilient material 26 on a valve seat 27 surrounding an inlet pipe 36, the casing also having an outlet 37. When seated the disc 28 abuts tangentially against the ring 26. A lubricant, provided in a channel 33, is forced pneumatically to the sliding surface of the pin 21 through an opening between two peripheral recesses. When a force is applied to a wear-resistant plastics pin 30 forced into pin 21 and a constant pneumatic pressure is applied from a pump through a fixed throttle to the inlet pipe 36 the disc 28 is displaced to the left in accordance with the magnitude of the force, air escapes through holes 37 round the casing 25a and a pressure gauge 41 between the throttle and inlet 36 measures the back pressure and so indicates the force. The load cell 22 may be used to measure the torque generated by a screw conveyor 9 in a continuously operating sludge centrifuge, in which a valve 45 in a liquid-supply line 16 may be adjusted by an electric motor 44 controlled automatically through an electric, hydraulic or pneumatic transmission line 43 in dependence on the pressure gauge deflection. Should a sludge outlet become choked and cause excessive torque a lever 23 controlled through a lever 20 by differential gearing 14 between the centrifuge rotor 1 and the screw 9 would turn and be held by a catch, sealing the valve 26, 27, 28 and causing the rotor to drive the screw at its own speed instead of 15 to 20 r.p.m. slower.

Abstract: 436,806. Loose-ball valves. HILLEN, J. A. V. M., 25, Rustenburgerweg, Bloemendaal, Holland. April 18, 1934, Nos. 11712 and 11713. Convention dates, April 21, 1933 and July 20, 1933. [Class 135] A loose-ball valve such as a discharge valve for ships for preventing return flow of liquids comprises a housing 1, Figs. 1 or 3, having ribs 6 in opposite walls thereof, the ball 4 being moved when the valve is open to a position 4<1> where it lies in a bend of the housing outside the path of outgoing liquid, but any reverse flow carries the ball back to its seating. In a modification, Fig. 4, the ball may rest on a lever 19 mounted on a shaft 18 carrying a weighted arm 20 which tends to hold the ball on its seating. The ball is usually of smaller specific gravity than the liquid, but in some cases a ball of greater specific gravity than the liquid may be used. The Specification as open to inspection under Sect. 91 describes also a modification wherein the outlet flange is parallel to and below the inlet flange of the valve. In another modification, Fig. 5 (Cancelled), the ball 4 is of greater specific gravity than the liquid and may be forced from its seating by means of a screwed rod 7 so that it moves along the ribs 6 out of the path of the liquid. In another modification, Fig. 6 (Cancelled), the ball is normally seated against the flange 2, but may be lifted to the position 4<1> by means of a headed rod 7 operated through lever mechanism 16, 14 from a handle 13. In another modification, Fig. 10 (Cancelled), particularly for connecting two containers which are alternately filled and emptied, a floating ball 4 may be forced on to either of the seatings 28, 29 by means of a member 11. When this member is raised the ball passes into the chamber 30. A gland wherein the friction and resistance to leakage are regulated according to the internal pressure of liquid in the valve is also described. This subject-matter does not appear in the Specification as accepted.
