Patent GB-380884-A (GB)
Title: Process for the recovery of tin or lead or antimony or bismuth or alloys of two or more of these metals, with or without precious metals
IPC: C22B5/00
Filed: 1931-07-20
Abstract: In a process for the recovery of metals such as tin, lead, antimony, bismuth, &c., or alloys of these metals with or without precious metals contained in the residues obtained during the reduction of materials containing these metals in the form of oxides by the process described in Specification 367,611, any cooling of the residues withdrawn from the furnace to a temperature below the solidification temperature of the reduced metals is prevented by conserving the heat in the residues or by supplying heat to them, in order to obtain the metals in a cohering molten form and the residues are shaken to facilitate the union of the metal particles.  Tappings from several furnaces may be collected in one container adapted to be shaken and preferably having heating means, a perforated false bottom, and tapholes below the bottom.  Agitation may also be carried out in a rotary tube or a shaking trough or hearth.  The yield of metal from the residues is increased by making up the charge into a paste with solutions of the requisite fluxes such as sodium carbonate, waterglass, &c., or by sintering the oxides to be reduced with or without additions of the fluxes before adding the reducing agent. If the sintering is carried out without or with insufficient fluxing agent a quantity of the flux may be added later to the charge in the reducing furnace.  The residues remaining after the separation of the metals may be further treated by a concentration or dressing process, for example sieve-jigging or ball-milling, and the recovered metal worked up into ingots by segregation and subsequent immersion in a metallic bath.  By using wood charcoal as reducing agent, the concentration of the residue may be wholly or partly obviated.  The residues in these circumstances contain no graphite constituents, and after the separation of the metals with or without separating a portion of the wood charcoal remaining unconsumed, may be further worked as by smelting in a blast or reverberatory furnace, if desired after briquetting.

Title: Improvements relating to railway signalling apparatus of the detonator type
IPC: B61L5/22
Filed: 1925-08-20
Abstract: 259,349. Sykes' Inter-locking Signal Co., Ltd., W. R., and Lascelles, T. S. Aug. 20, 1925. Detonator apparatus of the kind in which the detonator is automatically placed in position by the passage of the train acting on a treadle or the like is arranged beyond the signal to give warning that a signal at " danger has been passed. The detonators 5 are carried by a slide 3 normally retracted by springs or bv a counterweight 6. A slide 9 the inner end of which is opposite to, but spaced from, the end of slide 3 is adapted to be moved towards track rail 2 by the action of the train on a fouling bar or the like 10. A third slide 12 operated in conjunction with the usual signal is clear of the slides 3, 9 when the signal is at " clear," but is interposed therebetween as shown when the signal is at danger. Thus the slide 9 is moved idly when the is at " clear, ' but communicates motion through slide 12 to the slide 3 with the signal at "danger." Slide 12 is guided by rollers 15, 16 or by pin and slot, and provision is made for the necessary lateral movement., as by a pivot 14. The ends of the slides may be bevelled to allow the signal to be moved to " danger " if required when the treadle 10 is depressed. Where traffic is liable to move in a direction reverse of normal, as in shunting provision may be made to render the detonatorplacing inoperative under such reversed movement. For this purposes a second treadle located beyond the treadle 10 and operated first during reverse movement may be arranged, for example, to raise the end of slide 12 above slides 3, 9. Slide 12 may be operated electromagnetically in conjunction with light signals. Contacts such as 18 may be disposed so as to be held closed when the detonators 5 are in place and the slide 3 is in normal position, the contacts closing the circuit of a relay which in turn, when energized, holds open a local circuit including a visual or audible indicator. The relay circuit is broken and warning indication given if the detonators are displaced, or slide 3 is moved from normal position.

Title: Capacity-operated protective system
IPC: G08B13/26
Filed: 1959-06-18
Abstract: 867,136. Intruder alarm systems. UNITED STATES ATOMIC ENERGY COMMISSION. June 18, 1959 [Aug. 4, 1958], No. 20944/59. Class 118. [Also in Groups XXXVI and XL (c)] An intruder alarm system comprises a sensing capacitor, a transistor multivibrator with means for rectifying its output to provide a D.C. signal and a monitor responsive to sudden changes in the D.C. signal, thereby operating an alarm. The D.C. signal is fed to the monitor by a line which also provides a connection between one plate of a sensing capacitor and the collector of one stage of the multivibrator, the other plate being connected directly to the base of the same stage. In the embodiment described, the output from the multivibrator shown in Fig. 2, is fed to the bridge rectifier 36 from which a D.C. output is taken via a plug and socket to the line 77. The sensing capacitor 79 comprises a plate 78, for example a safe which is to be protected, separated by a dielectric layer, e.g. floor covering from the ground, which forms the other plate. The plate 78 can be connected via switch 14 to the base of transistor 30, the earth connection being made from 42 (Fig. 3) over line 77 terminal 40, capacitor 34 to the collector of the same transistor so that variation in capacity will vary the multivibrator output. The D.C. signal is fed over line 77 to the monitor unit (Fig. 3) in which it is amplified in transistor amplifier 51 and fed through capacitor 58 to a balanced relay winding 60. Any sudden changes in D.C. signal will thus cause current to flow through winding 60 and close contacts 63 to operate relay 64. Contacts 68, 69 close, completing the circuit to the horn 72 and neon 71. A cancelling switch 75 is provided for the horn, the arrangement being such that when the relay 64 releases the horn will again sound as a reminder to reset the switch. Desensitizing switches 8, 14 are provided in the detector which effectively connect the plate 78 of the capacitor to earth and also switch a different resistor in the emitter circuit of the transistors. A further switch 44 is provided in the monitor unit which when opened inserts a resistor 45 into the input line to the amplifier 51.

Title: Improvements in and relating to wireless receiving systems and the like
IPC: H04B1/16
Filed: 1921-08-08
Abstract: 192,429. Taggart, J. Scott-., and Radio Communication Co., Ltd. Aug. 8, 1921. Heterodyne receiving systems; thermionic detectors.-In a receiving arrangement for continuous waves, the incoming signals are applied to a thermionic valve the normal steady anode potential of which is zero, negative or only slightly positive, and on which is also impressed a locally-produced current of an audible frequency or of a high-frequency slightly different from that of the incoming signals. In the arrangement shown in Fig. 1, incoming signals are applied to the anode circuit of a two-electrode valve V, the anode A of which is maintained normally negative by a battery B<2>. A buzzer or oscillating valve B1 applies alternating potentials of audio frequency to the anode A, but when no signals are being received the battery B<2> maintains the anode sufficiently negative to prevent any current flow in the anode circuit even when the source B<1> tends to make the anode positive. When however signals are being received, the positive half cycles of incoming waves combine with the positive potentials from the source B' to overcome the negative potential of the battery B<2> and produce a current flow in the anode circuit through the telephones T. In a modification, Fig. 2, a three-electrode valve V is employed incoming waves being applied to the anode circuit in which are also included the receivers T. An audio frequency source of current variations S is impressed upon the grid G. Normally no current flows in the anode circuit since no anode battery is provided, but when signals are incident upon the aerial, the application of the signal potentials to the anode A enables the local source S to produce an audible indication in the telephones T. The local source S may be of a high frequency differing slightly from the incoming frequency, and, in another modification, the local variations are impressed on the anode circuit and the incoming signals are applied to the grid. The anode may be given a small fixed positive potential which may be tapped from a potentiometer across the filament battery. In a further modification, illustrated in Fig. 5, incoming signals are applied to the grid of a valve V<1>, across the anode and filament of which is connected the oscillating circuit L<3>, C<3> of a generating valve V<2>. the telephones being preferably inserted in the anode circuit of the valve V<2>. Incoming signals vary the conductivity of the valve V<1> which absorbs varying amounts of energy from the oscillating valve V<2>. The oscillating frequency of the valve V<2> may be made slightly different from that of the incoming signals to produce an audible beat note in the telephone T.

Title: Improvements relating to vehicle anti-skid brake control apparatus
IPC: B64C25/46
Filed: 1954-07-20
Abstract: 739,695. Fluid-pressure brakes. WESTING- HOUSE AIR BRAKE CO. July 20, 1954 [July 21, 1953; July 21, 1953], No. 21087/54. Class 103 (1). In decelleration control systems for preventing vehicle, particularly aircraft, wheels from skidding so many brake release and application cycles may be brought about by a control unit 6, such as that described in Specification 674,506, that the pressure on the reservoir 2 may be reduced to a value below that necessary to give an effective brake application. A cut-out valve device 7 is therefore connected to the reservoir 2 such that if the pressure therein falls below a certain value a piston 69 is forced down, to cut-off the supply of pressure to a chamber 38 in a valve locking device 16. Loss of pressure in chamber 38 allows a spring 42 to force down piston and rod 36, 41, to prevent the piston slide valve 17 from leaving its lowest position in which pressure is connected to the brake cylinder 3 from the operators manual control valve 5. Under these conditions even if the control unit 6 should operate bell-crank lever 53, 57 to open valve 51 to reduce pressure in chamber 24, the valve 17 cannot rise to vent the brake cylinder through port 28. In another embodiment, means are provided for locking mechanically the end of the bell-crank arm 57.

Abstract: 943,491. Driver's valves for vacuum brakes. KNORR-BREMSE G.m.b.H. June 17, 1960 [June 20, 1959], No. 21427/60. Heading F2F. A driver's vacuum brake valve includes an actuating lever 3, a housing 1, a valve surface on plate 25 which co-operates with valve seats 21, 39, both seats being movable independently of each other and relative to housing 1, and a piston 47 acted on by a spring 53. On rotation of lever 3, spring 35 raises piston 9 and plate 25 to connect atmospheric chamber 45 to the train pipe via bore 41, valve 39, 25, chamber 31 and port 33; the created pressure acting in chamber 49 and eventually spring 53 raises piston 47 and stem 37 to close valve 39, 25. For brake release, lever 3 lowers piston 9 to open valve 21, 25 and connect a vacuum source to the train pipe via port 15, valve 25, 21 and chamber 31, vacuum in chamber 49 moving piston 47 to close valve 21, 25. Should a leak occur in the train pipe, the piston 47 rises to open valve 21, 25 to reset the vacuum level. The spring 53 is adjusted by screw 51 to set the train pipe pressure and by fitting stops for piston 47, the member 9 can be moved to maintain valve 21, 25 or 25, 39 open.
