Title: Improvements in the manufacture of gaseous fuel from lime kiln gases
IPC: C10J3/00
Filed: 1924-05-03
Abstract: 233,137. British & Foreign Lime & Power Corporation, Ltd., and Reid, T. A. May 3, 1924. Addition to 188.022. Producers ; coking processes.-In plant for the production of gaseous fuel from lime kiln gases, in which a lime kiln burning limestone, dolomite or magnesite is worked in conjunction with two gas-producers each operated alternately as a producer and a converter for transforming carbon dioxide into carbon monoxide as described in the parent Specification, the hot gases from the producer acting as a converter are passed through a retort containing carbonaceous material. A lime kiln a is worked in conjunction with producers b, c and a retort d charged with bituminous coal. Valves g, h, m, v and x being closed and valves i, k, l, n, u and y being open, air is forced by a fan t through the retort jacketd<1> and pipe w entering the producer b, converter c and kiln a by valves u, y and k respectively. The producer gas passing through valve i enters the kiln at a<1> and meets the air entering at a<2>, whereby sufficient gas is burned to dissociate the limestone. The kiln gases pass into the upper part of producer c together with air from valve y and the content of carbon dioxide and water vapour is reduced to carbon monoxide and hydrogen which enter and carbonize the coal in retort d. The gases and volatiles pass to a scrubber a for removal of condensates and to an engine f, the exhaust from which is carried by a pipe f<1> to preheat the charge in lime-kiln hopper. Specification 200,596 is referred to.

Abstract: 985,983. Centrifugal separators. SIEMENS-SCHUCKERTWERKE A.G. March 27, 1961 [March 25, 1960], No. 11197/61. Addition to 933,224. Heading B2P. In a modified form of the apparatus described in the parent Specification for separating dust from a stream 4 of dust-laden gas flowing axially into a separating chamber 1, Fig. 1, through an inlet 2, 3, the potential flow set up in the chamber by the introduction of secondary air through a duct 6 is boosted by supplementary air supplied through one or more auxiliary ducts 15 disposed on the spiral path 7 of the potential flow and through a further duct 17 communicating with the chamber at a point level with, or upstream of, the downstream extremity of a flow-control, streamlined body 19 disposed axially of the chamber adjacent the inlet 2, 3, the cleaned air being discharged through an axial outlet 5 defined by an annular member 10. In order to reduce secondary air energy used to create the potential flow which ensures the setting up of rotary flow, guide vanes 22 are annularly disposed in the inlet 2 to impart a rotary motion to the crude gas. The vanes 22 have a radial cross-section increasing in area towards the wall of the inlet 2. The' annular member 10 may be provided at the region of maximum pressure above the entry of the duct 6, as illustrated by the curve 14, with an annular diffuser-like channel 13 through which any stray jet 12 in the region of the duct 6, which jet may carry with it dust separated in the chamber, is directed via a pipe 12a to the chamber or to the crude gas inlet. In modifications, an annular channel, of divergent or convergent shape, is provided between the member 10 and the wall of the chamber. In Fig. 4a, the channel 11 is in the form of an annular groove in the member 10 and contains a ring 31 connected to a tubular insert 30 into which the duct 6 opens. The stray jet 12 is deflected and returned to the chamber as shown by the arrow 32. A streamlined flow control element 33 may be arranged at a distance h from the lower end of the member 10. In Fig. 4b, the tubular insert depending from the ring 31 and the control element 33 are dispensed with and the duct 6 does not project into the chamber. The stray jet is deflected as at 12a and 40.

Filed: 1957-04-05
Abstract: 843,705. Drying wood chips. BUTTNERWERKE A.G. April 5, 1957, No. 11231/57. Class 34(2) Wood chips are dried by entrainment in a helically-circulating stream of hot air. As shown in Figs. 1, 2, the wood is fed from, hopper 3 into a chamber 1 and entrained in a stream of heated air entering the chamber tangentially at 2. Guide plates 15 disposed in the air inlet 2a control the direction of the air and thus the rate of axial flow of the material, and prongs 7 connected to a rotating shaft 5 rake the inside of the chamber walls so preventing the wood accumulating thereon. The wood is separated from the air in a cyclone 10 and the air is recirculated by a fan 11, some escaping to atmosphere through valve-controlled outlet 13, and make-up hot air being supplied to the chamber by the duct 4. In a modification, the raking device consists of a small rotary rake mounted adjacent to the air inlet and no supply of fresh hot air is provided, the air from fan 11 being heated up in a recuperator and recirculated. In another arrangement, dust particles contained in the material are discharged from the apparatus through a system of pivotally-adjustable vanes to a suction box arranged above the chamber and connected with a dust separator.

Abstract: 527,562. Massage ; piezo-etectric crystal mountings; magneto-striction devices. POHLMAN, R. April 14, 1939, Nos. 11425 and 11426. Convention dates, May 25, 1938 and Feb. 8, 1939. [Class 81 (ii)] [Also in Groups XXXV and XL] An apparatus for effecting massage by supersonic vibrations comprises a housing into which the vibration generator is built and which is adapted to be held easily in the hand and moved over the part of the body to be treated. The transformer for producing the high frequency current required may also be contained in the housing. Fig. 3 shows a inagneto-striction vibrator comprising a slotted nickel tube 17 clamped at 18 in an iron housing 19. The tube is magnetized by direct current passing through coil 22, and a high-frequency oscillating current is passed through coil 21 producing longitudinal vibrations in the tube. Fig. 1 shows a piezoelectric vibrator in which the crystal 7 is placed in front of a small air-filled chamber 4 mounted on a ceramic block 13. These are immersed in a liquid 9 through which the vibrations are transmitted to the body through membrane 10. Fig, 6 shows a modification in which the crystal 31 is cemented to the membrane 33, and the space 39 behind it is filled with oil to damp the vibrations during idle running. Alternatively a massive electrode may be cemented to the back of the crystal to damp the vibrations. Instead of the membrane 33 being applied directly to the body a detachable transmitter body 43, Fig. 8, may be used. This may be lens-shaped and of a length tuned to resonance, and it may have a cooling jacket 44. Fig. 5 shows a resilient membrane 33 on which the crystal 31 is mounted, so that when the apparatus is lifted from the body the crystal is withdrawn from proximity to the electrode 47 thus preserving the crystal from destruction.

Abstract: 161,985. Heide, R. von der. April 21, 1920, [Convention date]. Addition to 156,102. Inhalers and respirators. -Consists in using the valve control mechanism of the parent Specification, wherein the supply of nutritive gas is automatically controlled by movements of the breathing bag itself, to control the rate of flow of gas from a nutritive gas storage chamber g to a breathing bag e during the time elapsing after the commencement of delivery of gas from an oxygen &c. generating chamber a until that chamber is delivering at its maximum rate, or at any time when the rate of supply from chamber a is insufficient to meet the demands of the moment. Withdraws of air from a face-piece attached at c diminishes the pressure within the breathing bag e and, if the generator a is not supplying gas sufficiently quickly, the diminished pressure in e, as described in the parent Specification, opens the valve leading from the chamber g. The Specification also states that the rate of flow of the auxiliary nutritive gas may be controlled by direct manual pressure on the valve control lever or by indirect action by means of a cord pull or equivalent device.
