Abstract: 346,684. Lifting-jacks. P 0 W E L L, A. D., The Limes. New Street, and BRADBURY & SONS., Ltd., J., New Street Works, both in Braintree, Essex. Nov. 5, 1929, No. 33590. [Class 78 (iii).] A hydraulic jack has means for supplying compressed air to the jack reservoir to cause the pressure fluid therein to raise the plunger to the load-engaging position and has a compressed air pump for supplying pressure fluid to the plunger for lifting the load. The casing A carries a tubular extension F fitted with a nipple F<1> and the operating spindle E of a valve C, the spindle being provided with a handle D. A compressed air supply pipe is attached to the nipple and the air passes to a recess C<6> in the valve. The valve is set so that air passes from the valve through ports C2, A<5> into the reservoir A<1> and forces the pressure fluid therein through a non-return valve I into the plunger cylinder A<8> to raise the plunger to the loadengaging position. By partially rotating the valve C air passes through a lateral port C<3> to the distributing valve L, Fig. 6, of an air-operated piston J having a plunger K in tandem therewith, the plunger causing pressure fluid to pass through a port K<2> to the plunger cylinder A<8> to raise the jack. By further rotating the valve C a cam C<1> on the valve depresses a valve pin H<1> and opens the release valve H so that pressure fluid returns into the reservoir and the jack is lowered.

IPC: C22B34/00
Filed: 1956-11-06
Abstract: 810,086. Refining refractory metals. DU FONT DE NEMOURS & CO, E'. I. Nov. 6, 1956, No. 33915/56. Class 82(1) Refractory metals prepared by the reduction of their halides by metals are freed from contaminating reducing metal halides by passing the refractory metal, under an inert atmosphere, through a furnace from which ,the reducing metal halide is removed as a liquid and vapour by heating to a temperature below the melting point of the refractory metal but above the boiling point of the reducing metal halide. The apparatus shown consists of a tubular conduit, which may be inclined up to 5 degrees from the horizontal, having a cool zone 8, constructed of steel, in which the refractory metal is purged of air by inert gas flowing through inlet 9 and outlet 10, a melting zone 12, constructed of graphite, in which the metal is heated to about 800‹C., molten reducing metal halide draining through port 23, heated sump 24 and outlet 25, a vaporization zone 13, constructed of graphite, in which the metal is heated to 1400‹-1700‹C. by induction coil 22 to vaporize the reducing metal halide and a zone 14, constructed of steel, in which the purified metal cools under an inert atmosphere introduced through inlet 19, cooling being aided by a water jacket 16. A continuous process is achieved by loading the refractory metal into a graphite boat 29 furnished with drainage ports 30 which is placed inside the conduit by removing end plate 6. After purging in zone 8,. the end plate is removed, another boat is placed in position and is moved into zone 8 by the action of hydraulic ram 33 thereby moving the first boat to zone 12, after which plate 6 is replaced. This series of operations is repeated and boats containing treated metal are taken out of the conduit, after cooling in zone 14, by removal of end plate 7. Examples of metals that may be treated are Ti Zr, Be, Hf, Cr, V, U, Th, Ta, W and Mo,

Title: Magnetron telegraphic repeater
IPC: H04L25/24
Filed: 1938-11-22
Abstract: 504,708. Code telegraphy. CREED & CO., Ltd. Nov. 22, 1938, No. 33946. Convention date, Dec. 20, 1937. [Class 40 (iii)] A two-way repeater. uses magnetrons instead of contact-making relays, in order that distortion due to the transit time of relay armatures maybe avoided. In a system in which the line is closed in the marking or idle condition, the magnetrons 1, 2, Fig. 1, which'send on signals to the lines 26, 25 respectively, are so biassed by their windings 9, 10, that they are non- conducting in the absence of marking current in their line windings 5, 6 or echo-suppression windings 13, 14. When the lines 25, 26 are in the marking condition, tubes 1, 2 are both rendered conductive by the line current in their windings 5, 6. When a transmitter at 27 sends a spacing impulse by breaking circuit, the sending.on magnetron 1 becomes nonconductive, thus interrupting line 26 so as to send on a spacing impulse to line 26. The echo-suppressing magnetrons 3, 4, on the other hand, are so biassed by their windings 11, 12, that they are normally conductive, but can be rendered nonconductive by current in their line windings 7, 8, or echo-suppressing windings 15, 16. When the lines 25, .26 are in the closed or marking condition, therefore, magnetrons 3, 4 are nonconductive ; but when a spacing condition is received on line 25, magnetron 3 becomes conductive and, by closing the circuit of windings 16, 14, prevents the condition of valves 4, 2'from being changed by the cessation of current in their line windings 8, 6 when the spacing impulse is sent on. Thus echo from line 26 into line 25 is suppressed. A marking impulse from station 25 restores magnetrons 1, 3 to their marking condition. In a modification, Fig. 2, (not shown), only two magnetrons together with two triode valves are used, and the line is open in the marking or idle condition. In another modification, Fig. 3 (not shown) each of the sending on magnetrons 1, 2, has only two windings, one of which is shunted by a retarding condenser. Substation circuits. In a system in which the marking condition is distinguished by current in the local circuits and no current in the line, the recorder magnet is so biassed by winding 125, Fig. 4, that it remains in the marking condition until current appears in the line 122, whereupon the grid potential of the valve rises and anode current in the winding 124 overpowers the biassing current and releases armature 129. During transmission of a space signal from the station to the line 122, current in the transmitter relay 134 disconnects the line. A substation circuit without a valve and serving the same purpose is described with reference to Fig. 2 (not shown).
