Abstract: 946,104. Control of D.C. motors; controllers. LANSING BAGNALL Ltd. April 12, 1961 [April 21, 1960], No. 14056/60. Headings H2B and H2J. The driving motor 114 of a fork-lift truck has two series field windings F1, F2 which may be arranged in series or parallel with each other by electromagnetic contactors C7, C8 and is powered by two battery sections 71, 72 which also may be connected in series or parallel by further contactors C5, C6. Two series resistors R1, R2 are short circuited in turn by contactors C3, C4 during acceleration. R2 is also used for rheostatic braking, during which an additional field winding F3 is connected across the battery sections in parallel; the connection is made through contacts AC1 and AC2, one of which opens when its corresponding contactor C1 or C2 closes to energize the motor in the direction determined by a reversing switch 87. The contactors have operating coils S1 ... S9 energized through microswitches MS1 ... MS6 in a pedal operated master controller, the sequence being (i) (pedal released), rheostatic braking established, batteries in parallel; (ii) motor connected to battery with its field windings F1, F2 in series; (iii) R1 short circuited; (iv) R2 short-circuited; (v) battery sections rearranged in series and R2 re-inserted; (vi) R2 again short-circuited; (vii) F1, F2 rearranged in parallel. A torque sensitive switch 89, operated by movement of the motor body against resilient mounts changes the field connections back to series automatically when a given torque is exceeded. An hydraulic pump motor 82, controlled by switch 84, provided power for the fork lifting apparatus but at step (v) and above its circuit is broken by MS4. A warning lamp 86 is illuminated when key switch 19 is turned on and extinguished when the pedal is depressed. The control circuits are energized through a thermal overload trip 182. The pedal operated controller (Fig. 4) comprises six microswitches 31 closed successively by a cam 32 linked with an adjustable, quickreturn, dash-pot 37. A lost motion link (Fig. 2, not shown) connects the cam arm spindle 45 with the pedal (not shown).

Title: A continuous process for the roasting of arsenopyrites ores
IPC: C01B17/52
Filed: 1958-05-02
Abstract: The continuous process of roasting arsenopyrites ores of the parent Specification comprising preheating the ores in a preceding separate stage by direct heat-exchange with a portion of the SO2 gases from the subsequent roasting stage, passing the preheated ore to the roasting stage, and recovering the remainder of the SO2 gases from the roasting stage as arsenic-free gas is modified by introducing O2 into the roasting stage in amount sufficiently in excess of the p stoichiometric requirement for roasting to ensure that the temperature of the ore in the preheating stage is raised to at least 800 DEG C. by combustion therein of labile S with the excess O2 in the portion of SO2 gases from the roasting stage passing in direct heat-exchange with the ore in the preheating stage, and retaining the ore in the preheating stage for a period of time insufficient for the distillation and combustion of the whole of the labile S. Arsenopyrites ore of size 0.4-0.1 mm. may be preheated to 800-815 DEG C. and arsenic sulphide is separated from the resulting SO2 gases. After 10-20 minutes residence time in the preheating stage, where the ore is also heated by indirect heat-exchange with the remainder of the SO2 gases from the roasting stage, the ferrous sulphide with some labile S is roasted by a blast of hot air at under 1000 DEG C.  Most of the lead is also removed in the preheating stage.  Specification 755,344 also is referred to.

Title: Improvements in recovering gases which have been absorbed by solids
IPC: C10K1/32
Filed: 1920-05-21
Abstract: 170,323. Thermal Industrial & Chemical (T.I.C.) Research Co., Ltd., and Morgan, J. S. May 21,1920. Volatile liquids, recovering.- For recovering vapours absorbed in solids such as charcoal and alumina, the solid is caused to travel through a bath of liquid metal such as molten lead heated to the requisite temperature, or through a series of such baths maintained at gradually increasing temperatures so as fractionally to expel the gases; in the latter case the heated solid may be returned to the bath of lower temperature so as to carry into the latter heat acquired in the bath of higher temperature. When recovering ethylene &c. which has been absorbed from coal or other gas, the saturated charcoal may first be passed through a bath of molten alloy maintained at 120‹ C., and then through a. bath of molten lead at about 350‹ C.; the charcoal is afterwards cooled by passage through the first bath, through a bath of cooled mercury, or by the stripped and cooled gases; and benzene may be recovered from the charcoal of the preliminary absorbers in a similar manner, but generally these will be charged with charcoal already saturated with ethylene. A convenient apparatus comprises baths a, b arranged close together and each containing two pairs of rotating paddles c, c<1>, d, d'; the charcoal enters the bath a by a shoot k, is carried beneath the molten metal by the paddle c, falls through the adjacent openings h into the bath b, is carried therethrough by the paddle d, then passes to the other side of the bath, and is carried back in a similar manner by the paddles d<1>, c<1> which rotate in an opposite direction to the paddles d, c; the vapours which escape are collected separately and are led away through suitable outlets in the cover.

Title: Improvements in or relating to a cathode-ray tube device for generating ultra-high-frequency oscillations
IPC: H01J43/02
Filed: 1941-11-03
Abstract: 556,662. Cathode-ray tubes. PHILIPS LAMPS, Ltd. (Naamlooze Vennootschap Philips' Gloeilampenfabrieken). Nov. 3, 1941, No. 14177. [Class 39 (i)] In a frequency multiplier, an electron beam generated by cathode 1, Fig. 1, modulator 3, anode 5 and coil 6 is given a rotary deflection by plates 7, 9 so that it traverses an apertured disc 25. Electrons passing the apertures of disc 25 strike the secondary-emitting target 37. The secondary electrons are further multiplied at electrode 31 in the same plane as and insulated from disc 25, and proceed to collector electrode 41 in the plane of target 37. Electrode 31 may be replaced by several, for example, three electrodes disposed alternately in the planes of disc 25 and target 37 ; discs 29, 33, 39 insulate and support the two structures. Each electrode is covered by an accelerating grid 32 connected to the next highest potential. The collector 41 is housed within an expanded end D of a coaxial line 45, 47 which carries a shielding grid 43. The cavity D is designed to resonate at the generated frequency and to be correctly coupled to the line. The apertures in electrode 25 are preferably wider at the ends, as shown in Fig. 5b, so that variation of the diameter of the beam under the action of electrode 3 will not result in a variation of the proportion of the beam current passing to target 37. The subject-matter is identical with that of Specification 31206/45 (as open to inspection under Sect. 91).

Title: Improvements in and relating to glow starter switches for electric discharge lamps
IPC: H05B41/08
Filed: 1946-05-13
Abstract: 627,052. Thermal switches. GENERAL ELECTRIC CO., Ltd., and NOBLE, S. H. May 13, 1946, No. 14401. [Class 38(v)] A glow switch for starting discharge lamps comprises a U-shape bimetal 15 supported by a terminal 14 and slidably carrying a bar 16 having a contact 17, the other contact 13 being mounted on the terminal 12. On heating, the free limb of the bimetal moves outwards to engage a stop 19 on the bar 16 whereby the contact 17 is moved to engage the contact 13. The glow then ceases and the bimetal cools, but the contacts 13, 17 are not separated to start the lamp until the free limb engages another stop 18 on the bar. The delay produced by this lost-motion coupling ensures that the contacts are positively disengaged and contact chatter is avoided. A thin wire 20 may be connected between the bar 16 and the terminal 14 to make certain that these parts are at the same potential.

Filed: 1969-03-19
Abstract: 1,247,099. Gas cooling method and apparatus. BADISCHE ANILIN- & SODA-FABRIK A.G. and SIEGENER A.G. GEISWEID EISENKONSTRUKTION BRUCKENBAU VERZINKEREI. 19 March, 1969 [2 April, 1968], No. 14506/69. Headings F4K and F4S. A gas, in particular cracking or synthesis gas, is cooled by bringing it into contact with a molten metal or alloy the temperature of which may be regulated by a cooling medium e.g. water or stream passed through or into the molten metal e.g. via heat exchange tubes 14. The molten medium may comprise bismuth, tin or thallium, or lead alloys containing any of these metals or silver. In an apparatus shown for carrying out the method, the molten medium M is contained in a vessel 1 partially lined with heat insulation 2. The gas enters the vessel via a pipe 19 and sieve 21 from which it flows upwardly through the molten medium to outlets 22 from the vessel. Unwanted accumulations Sch on the surface of the molten medium are removed to an outlet 24 by blast nozzles 23. The coolant for the molten medium circulates through a heat exchanger suspended from the roof 8 of the vessel, and comprises inlet tubes 10 communicating via headers 11 and downflow tubes 12 with headers 13 from which tubes 14 extend upwardly to further headers 15. These lead via tubes 16 and headers 17 to outlet pipes (18, Fig. 1) for the now heated coolant which in the case of water or steam may be conveyed therefrom to a boiler drum. Regulation of the rate of heat transfer may be effected by raising or lowering the inlet temperature of the cooling medium, or (using inlets and outlets 27, 28) of the level of the molten medium M. At the lower end of the casing 1 is a space 5 defined by a bridge member 2a of heat resistant material e.g. ceramic, and containing a tube 6 to which a heating medium is supplied to maintain molten the medium M.

Title: Improvements in or relating to electric relays incorporating gas-filled tubes
IPC: H04L25/24
Filed: 1931-05-16
Abstract: 378,868. Valve amplifying circuits ; code telegraphy. ELECTRICAL RESEARCH PRODUCTS, Inc., 195, Broadway, New York, U.S.A.-(Assignees of Burton, E. T. ; 97, Cypress Street. Millburn, New Jersey, U.S.A.) May 16, 1931, No. 14549. Convention date, May 21, 1930. [Classes 40 (iii) and 40 (v).] The invention relates to gas-filled tube relays in which the magnitude of the output is independent of the magnitude of the input and an uncontrolled glow or arc persists until quenched or interrupted by some other agency than variation of the potential of the control electrode. The quenching may be effected by a limiting device in the anode circuit which may comprise a condenser shunted by a resistance or alternatively an alternating voltage operating under the control of the signal &c. input may be applied to the anode circuit to quench or stop the arc. Fig. 1 shows a zero wander correction circuit in which an amplifier 10 is connected to the cable and applies the signals through magnetically biased impulse coils 1C of the type described in Specification 312,338, [Class 40 (iii), Telegraphs, Electric], to a receiving circuit 15. When a secondary impulse in either winding 16 or 17 exceeds the grid bias of glow discharge tube 1 or 2 a glow discharge operates relay 4 directly to correct the zero wander through network 8. Relay 4 and the resistance capacity network 8 are of the type described in Specification 270,354, [Class 40 (iii), Telegraphs, Electric]. Quenching the discharge is effected by resistance-condenser combination 5, 6. In a modification, Fig. 2 (not shown), quenching is effected by a transformer coupling between the anode circuits so arranged that the starting of a discharge in one of the valve circuits quenches the discharge in the other valve of the pair. Alternatively a capacitive coupling between the anodes may be used for the same purpose. Fig. 4 shows a relay arrangement for signal shaping in which the gas-filled tubes 1, 2 deal with positive and negative voltages respectively and are provided with auxiliary gas-filled or thermionic tubes 20, 21 for quenching through transformers 23, 24. Fig. 6 shows a peak voltmeter for determining voltages in excess of a given value utilizing a pair of gas-filled tubes 41, 42 in which the potentiometer 43 determines the voltage at which the discharge occurs. Quenching, is effected by resistance condenser combination 47, 48 and a record is made by a magnetic device 44 of the siphon recorder type. A number of such recorders with different biasing voltages may be used to record different peak voltages. Specifications 297,696, 315,821, and 318,989, [all in Class 40 (iii), Telegraphs, Electric], also are referred to.
