Title: Improvements in or relating to the treatment of blood
IPC: A23K10/24
Filed: 1964-04-20
Abstract: In an apparatus for treating animal blood to render it suitable for further handling, the blood is pumped at a controlled rate from a storage tank (which may include a mechanical stirrer) to the base of a vertical duct (which provides a liquid head), where steam is injected into it from lateral apertures in a short pipe extending upwards into the duct.  Steam is also admitted to a manifold surrounding a perforated part of the duct a little above the first-mentioned steam admission, and valves are provided to permit controlled inflow at either or both locations.  A mixture of (a) a homogeneous mass consisting of blood solids combined with water and (b) free water, is formed, and passes from the top of the duct downwards, perferably to the interior of a rotary perforate drum rotating about an inclined axis above a trough, also inclined.  Free water passes through the drum into the trough, while the remaining mixture flows down into a hopper feeding from above into a horizontal compression-and-extrusion press.  The cage of the press (to the right of the hopper) preferably consists of an annular assembly of narrowly-spaced horizontal parallel bars and is closed at the outer end by a hydraulically-retractable cover (which may be perforate). Pressure is applied (by a hydraulically-actuated piston located to the left of the hopper) in two stages-first a lower pressure to express part of the water, then a higher pressure, to express further water and to cake the mass, after which the cover is retracted and the cake ejected.  In another embodiment the rotary drum is omitted, the free water in that event draining away through the cage of the press.  Pneumatic devices may be provided for conducting each cycle of operations in a timed sequence.

Title: Improvements in or relating to electric circuit breakers and fluid operating mechanisms therefor
IPC: H01H33/32
Filed: 1945-06-26
Abstract: 594,105. Automatic circuit breakers. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. June 26, 1945, No. 16292. Convention date, July 18, 1944. [Class 38(v)] In a fluid-actuated automatic circuitbreaker, an exhaust valve is actuated in response to closure on fault conditions, so as rapidly to dump the fluid from the working side of the fluid motor. The circuitbreaker is closed against a spring 77, by a rod 35 actuated by a piston 93 when compressed-fluid from an inlet valve 103 is admitted to a cylinder 13, the rod 35 being also connected to a lever 19, which cooperates with a retaining-latch mechanism, trippable by an overload device 69. The lever 19 is pivoted at 21, and carries a roller 33 which engages a main latch-lever 39, pivoted at 41 and biased by an adjustable spring-plunger 45. The lever 39 is ineffective alone, and is itself engaged by the tail portion 59 of an auxiliary latch-lever 55, pivoted at 57 and operable to release position, against a spring 63, by the plunger 67 of the trip-device 69. The lever 55 is held in a tripped position by a lever 83, normally engaged by the lever 19 but movable by a spring 85 when the breaker opens, so that a part 91 thereon engages the lever 55 until the breaker is reclosed. If the breaker is closed on an overload, the tripdevice 69 releases the latch mechanism, and in order to ensure rapid exhausting of the cylinder 13, an electromagnetic valve 139 opens to permit fluid to pass from cylinder 13 via channels 137, 138, and cause an adjustable pilot-piston 133 to initiate the opening movement of an exhaust valve 109 comprising a plurality of pistons 121 cooperating with exhaust ports 123. As soon as the pistons 121 are " cracked " open, the rush of fluid forces the valve 109 to fullopen position. Return of the valve 109 under the action of a spring 117 is retarded by the fluid trapped behind the piston 133 exhausting to atmosphere through a bleeder-valve 159. A bleeder-valve 153, prevents fluid which might leak past the righthand piston 121, from falsely opening the valve 109. The Specification as open to inspection under Sect. 91 describes also a modification wherein a piston-type exhaust valve is initially opened by trapping leaking fluidpressure above the piston. This subjectmatter does not appear in the Specification as accepted.

Abstract: 145,074. Reno, E. V., and Bois, J. A. C. Jan. 29, 1914, [Convention date]. Valves; valve-gear.-A split cylindrical slide valve 1, for inlet or exhaust, arranged in a chamber open to the working cylinder, is screwed on to a sleeve 13 carried by a cross-bar 12 on the valve-rod 11, and is withdrawn into a cavity when the inlet or exhaust port is open, in order to protect it from contact with the hot gases. For this purpose, the rod 11 slides in a guide 14, Fig. 7, which has upstanding parts 18 which fit the interior of the valve. The flange 15 of the guide 14 bears on a leather or other washer 16.. The valverod 11 is not a tight fit in the guide, and the gases under pressure from the cylinder enter the chamber 23 around the valve-rod, and assist the downward movement of the valve for opening the cylinder port 4 and maintain contact between the cam and valve-stem. The valve 1 is recessed at 8 at the part that covers the port and is provided with an internal square screw-thread, and sawcuts 37 are made in the threaded part to give elasticity. The split edges of the valve are recessed to receive a retaining screw. The Specification as open to inspection under Sect. 91 (3) (a) describes also a modification in which the split valve 1 is screwed on a piston with closed upper end actuated by a half-speed crank and a. connecting-rod. This subject-matter does. not appear in the Specification as accepted.

Title: Improvements in electrically operated time delay devices
IPC: H01H71/44
Filed: 1949-06-21
Abstract: 680,336. Automatic circuit-breakers; electromagnetic switches. FOSTER TRANSFORMERS & SWITCHGEAR, Ltd., and BAGNALL, R. I. June 20, 1950 [June 21, 1949], No. 16450/49. Class 38 (v) An electromagnetic time delay device primarily for overload tripping functions in circuit-breaker, has two windings 9, 10 which act differentially on a common armature and have, or form parts of circuits having, different temperature coefficients so that as their temperature rises under overload conditions, the distribution of current in the two windings changes and the armature is operated to produce tripping. In Fig. 1 the windings 9, 10 are wound on opposing magnet cores 5, 6 on a common yoke 4 on which the armature 7 is pivoted. The windings are connected in parallel and the winding 9 is in series with a resistance 11 having a high positive temperature coefficient, whilst the winding 10 may be in series with a resistance 12 having a low positive or a negative temperature coefficient. The armature is initially against an adjustable stop 8 and may be normally biased by springs or gravity. Under overload conditions, the heating of the resistances and windings by the excessive current causes the reduction of the current in winding 9 relative to that in winding 10, so that the force exerted :by the latter overcomes that of the former and the bias to move the armature 7 to its alternative position against the core 6. In Fig. 2 the windings 9, 10 are of unequal cross-section and wound on a common tube former 14 on a yoke 4 having a limb 13 extending between the windings. The plunger-type armature 15 acts on a striker pin 16 and a resistance strip 18 of low positive or negative temperature coefficient is connected in series with the larger coil 10. in each case the coil 10 may have more turns than the coil 9 so as to produce an ininstantantaneous action under very heavy overload conditions and to assist in producing in inverse time delay with reference to the magnitude of the current.
