Title: Improvements in or connected with apparatus or kilns for the drying and distillationof carbonaceous substances
IPC: C10B53/02
Filed: 1921-03-15
Abstract: 181,794. Alexander, H. March 15, 1921. Gaseous-fuel furnaces.-Plant for drying and distilling fuels such as coal, lignite, peat, kelp, wood refuse, or vegetable matter comprises a drying shaft discharging into complete gasification apparatus and heated by the hot gases from the " blowing " period. The complete gasification apparatus includes two retort and producer units having between them a retort in which the material is partially distilled. The material from the drying-chamber 7 is distributed from hoppers 8 into charging hoppers 10 arranged at the top of the carbonizing-units 12.. The producers 14, 14<a>, retorts 17, 18 and a retort 19 are filled with the material to be treated. Air supplied through ports 24, 24<a> renders the material in the generators incandescent and the gases generated are burned in the brickwork 21 surrounding the retorts with secondary air from ports 23, 23a, the hot combustion products passing up through ports 28a into the drying chamber 7. After closing the blast and secondary air valves and the stack valve, the gas outlet 25 from the retort 18 is opened, steam is admitted through port 28a superheated in the brickwork 21 generating water-gas in generator 14 and the gases pass through ports 30 and up through the generator 14a and retort 18 to the gas outlet 25. Carburetting material and a stream of gas may be supplied to the brickwork 21<a> and the gases caused to mix at the top of generator 14a with the water-gas before it enters the retort 18. The sequence of operations is reversed after the next blow. The material in the retorts 17 and 18 is completely gasified and that in the retort 19 is thoroughly dried to produce various by-products and a residue for use as a fuel.

Title: An improved process for the preparation of barium chloride and other chlorides of the alkaline earth metals
IPC: C01F11/28
Filed: 1919-04-01
Abstract: Sulphuretted hydrogen and an alkaline earth chloride are obtained by heating an alkaline earth sulphate such as barytes, celestine or gypsum with magnesium chloride and a carbonaceous reducing agent such as coal.  Alternatively, the coal &c. may be omitted, a higher temperature being then necessary.ALSO:An alkaline-earth sulphate, such as barytes, celestine or gypsum, is heated with magnesium chloride and coal or other carbonaceous reducing-agent.  Sulphuretted hydrogen is evolved, and an alkaline-earth chloride and magnesia are produced.  The alkaline-earth chloride is leached out, and the magnesia may be dissolved in sulphuric acid.  When it is desired to make barium sulphate by treating the barium chloride with sulphuric acid, the hydrochloric acid evolved may be used to convert the magnesia into magnesium chloride so as to make the process cyclic. The alkaline-earth sulphate may be heated with magnesium chloride without a reducing-agent, at a higher temperature, but with inferior yield of alkaline-earth chloride.

Title: Improvements in or relating to grid-controlled mercury arc rectifier installations
IPC: H02H7/127
Filed: 1959-03-11
Abstract: 870,407. Converting. SIEMENS-SCHUCKERTWERKE A.G. March 11, 1959 [March 11, 1958], No. 8502/59. Class 38 (2). A grid-blocking arrangement for protecting a mercury arc converter when a short-circuit or back-fire occurs comprises a bi-stable flip-flop circuit connected through a unidirectional conducting device to a grid control circuit. Converter A supplied through mains transformer K has a grid control set B which is supplied with unidirectional control voltage U st . The flip-flop circuit includes a transistor Tl with resistances R3, R4, R5 chosen so that T1 is normally conductive and its collector is at potential U2 which is higher than all values of U st  so that no current flows through diode D1. In the event of a short-circuit or back-fire in the converter the negative current at point E increases, setting up a negative potential at the base of a second transistor T2, overcoming the positive potential set up through resistances R2, R6. T2 therefore begins to conduct and the base of T1 is driven positive through resistances R5, causing T1 to stop conducting. Its collector potential falls and the control potential U st  causes current to flow through diode D1 and resistance R1 cutting off the grid firing pulses to A. The flow of current through D1 causes the base of T2 to be brought to a negative potential through R1, R2 so that the circuit remains in this state after the disturbance has ended. Transistor T3, connected to T2, operates a relay H to signal the presence of the fault. The converter is restarted by operating push-button M.

Title: Improvements in or relating to pumping systems for wells or the like
IPC: F04B17/04
Filed: 1929-03-15
Abstract: 307,893. Hild, F. W. March 15, 1928, [Convention date]. Actuating by rope and toothed gearing; speedvarying devices; air vessels.-A pump for oil wells &c. is actuated through a flexible cable 33 by a drum 32 which is driven alternately in opposite directions by a unidirectional motor 61 through gear wheels 52, 51, a differential gear 56, and' a sprocket chain 44. The wheel 51 is fixed to a level wheel 46 of the differential and drives the other bevel wheel 47 through the pinions 57, which are rigidly attached to a shaft 49 carrying the sprocket wheel 45 of the chain 44. The shaft 49 drives through a chain 67 a compressor or pump 66, which delivers through a pipe 77 to a threeway valve 69. The valve 69 is periodically operated by an oscillator 71 driven by the drum 32 to connect the pipe 77 alternately to a receiver 89 through a pipe 94, and to an air chamber in the pump through pipes 87, 88, and 22. The sprocket wheels 41, 42 are loose on the shaft 36 of the drum 32, and are connected thereto by clutches 38, 39. To effect the upstroke of the plunger 6, the motor 61 drives the compressor 66 through the differential and sprocket chain 67 until the load on the compressor increases to such a degree that the wheel 47 lags relatively to the wheel 46, thus causing the pinions 57 to drive the shaft 49 and chain 44. At the end of the upstroke, the oscillator 71 operates the valve 69 to connect the compressor delivery to the air chamber in the pump, thereby reducing the load on the compressor and the wheel 47, so that the weight of the pump rods &c. rotates the shaft 49 and pinions 56 in the reverse direction, driving the compressor and the motor 61. The rate of travel of the pump rods is regulated by adjusting a valve 85 in the delivery of the compressor. At the bottom of the stroke, the oscillator again operates the valve 69 to connect the compressor to the receiver 89, and the upstroke begins again. The compressor may be replaced by a liquid pump, which may be used for pumping the liquid raised by the main pump to a higher level. Or the pump may draw liquid from a container 95 and pump it in either a closed circuit through the pipe 77, valve 69, and pipe 97, or through the receiver 89, according to the direction of the stroke of the plunger 6. The apparatus may be used for hoisting operations other than pumping.

IPC: B65H67/02
Filed: 1931-03-19
Abstract: 365,871. Creeling yarn-winding frames. REINERS, W., 48, Rheyderstrasse, Gladbach, Munich, Germany. March 19, 1931, No. 8523. Convention date, March 22, 1930. [Classes 120 (ii) and 120 (iii).] In creeling winding frames by the aid of a mechanical conveyer which conveys bobbins to the spindle units of the winding frame and places them in their charging and working positions, a mechanism is provided to strip the empty bobbins from their pegs automatically. Creels 23, Fig. 2, to be unwound on to packages 48 are supported on creel pegs 24 secured to sleeves 26, Fig. 9, rotatable about axes 25. Each sleeve carries four equally spaced pegs so that an empty peg is disposed opposite a fresh creel 23 supported in a carriage 35. The carriage contains a number of creels, which slip down a slope 36 therein or are directed by conveyers therein and are fed by star wheels 38<c> to a channel 39 in the lower part of the carriage, and travels on rails 34 along the machine. Associated with each creel mounting is a fixed cam adapted to actuate a spring- pressed lever, which ejects the creel from the channel 39 on to the creel peg 24 opposite it, as the carriage moves past it. An arm 47 on the carriage then engages the downturned peg 24 to rotate the sleeve 26 and lift the fresh creel to the vertical operative position, a fixed cam 30 adjacent the pegs simultaneously engaging the empty creel to eject it from its peg on to a discharge conveyer. The yarn from the creel passes through a tensioning device comprising pegs 56, Fig. 10, on a stationary arm 55 secured to a fixed shaft 54, and pegs 59 on one arm of a bell-crank lever 58 rotatable about the shaft 54. The other arm of the bell-crank lever is weighted to keep the lever against an adjustable stop 57 on the arm 55. The shaft 54 also carries a rotatable lever 62 having one end provided with a feeler 66 and the other end secured to a rod 63 depending from the cradle 50 of the wound package. As the carriage is about to deliver a fresh creel to the creel peg, an inclined projection 68 on the carriage depresses the feeler 66 and thereby causes the rod 63 to raise the cradle 50, a stop 60 on the bell-crank lever 68 being engaged by an arm 64 on the rod 63 to raise the bell-crank lever and open the tensioning device. A lever 53 then locks the cradle 50 in its upper inoperative position until it is manually released. In modifications, each creel 23, Fig. 18, is carried by a spring clip 80 on an endless belt conveyer 78 until released by a projection 81 on the carriage 35, whereupon it falls down a funnel to the channel 39, or the funnel may be dispensed with and the ejecting mechanism of the carriage 35 push the creel directlv from the convever on to the creel peg. The belts 78 may be replaced by an intermittently rotated carrier wheel. In all of the forms, the carriage may be provided with a seat for the operator and a blower to drive away dust &c. from the machine.
