Title: Improvements in or relating to the gasification of small particles of solid fuel
IPC: C10J3/46
Filed: 1954-12-02
Abstract: 779,202. Gas manufacture. STEINMULLER GES., L. & C. Dec. 2, 1954 [Dec. 7, 1953], No. 34919/54. Class 55 (1). Small solid fuel is gasefied by partial combustion with air &c. supplied from below a grate on which a layer of fuel is distributed radially outwards from a central overhead feed, part at least of the fuel being gasefied in a fluidized state. A fuel tube 1 depends into the mouth of a separator 2 from which a tube 12 leads to a distributer 5 comprising a cone 15 above a hollow core 25 with a hood 19 at its apex of adjustable height so that fuel supply to a grate 9 preferably with involute bars, may be regulated. Hot and cold air are respectively supplied through pipes 17, 27 to a chamber 6 and through a sieve 8 to an annular distributing chamber 18; a portion passes through a central duct 16 to cool the underside of cone 25. The reaction chamber 3 communicates with the separator 2 through a slit 26 between the wall 22 and a cover 21 which carries the offtake 30. The chambers 3, 4, the cover 21 and off-take 30 are preferably lined with fireproof blocks behind which cooling tubes may be arranged. Or the walls may consist of uncooled blocks if, e.g., slag is to be withdrawn molten. Parts within the inner wall of the reaction chamber may have water or steam cooling means. Coke dust separated out by the double deflection of the gas on its way to the offtake passes with fresh fuel to the distributer. In a modification the lower cone of the distributer is bladed and is rotated to assist in spreading the fuel uniformly; the grate is also rotated. In another the upper cone of the distributer is omitted and the lower end of the reaction chamber wall is thickened to provide a narrow outlet for the issuing fuel.

Abstract: 747,363. Animal food. HILLER, S. Dec. 22, 1953 [Oct. 15, 1953], No. 35574/53. Class 5 (2). Fish meal is prepared by cooking and partially dehydrating fish to an intermediate moisture content wherein there is no visible excess moisture and the fish is fibrous in character, pressing and then further dehydrating, the cooking and partial dehydration being effected by continuously conveying the fish in a closed circuitous path with simultaneous agitation. 25-40 per cent is the specified intermediate moisture content. Oil is separated from the press effluent and the aqueous phase of the effluent is added to the pressed fish before further dehydration. In operation, raw fish is cooked and partially dehydrated in a dehydrator 2 provided with a discharge 4 through which the fish passes to a hopper 6, then a press 7. Effluent passes to a collector 8 and is discharged through an outlet 9. A mixer 11 breaks up the press cake which is further dried by hot air from a pipe 12, and also in a drier 16. The dehydrator (Fig. 2) comprises side by side cylindrical chambers 21 connected by a duct 22 at each end. Heat is applied both externally and internally of the fish mass, externally by means of steam jackets 23 around each chamber, and internally by means of hollow steam shafts 32 and hollow screw flights 29 of screws 28, steam being admitted through inlet pipes 33 and 36. At the ends of the dehydrator, the screw flights of the screws are offset relative to each other, thereby conveying the fish in a closed circuitous path.

Abstract: 368,731. Filtering gases. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and LAMBERT, B. VINCENT-, Fraser & Chalmers Engineering Works, Erith, Kent. Dec. 1, 1930, No. 36206. [Class 8 (ii).] Bag filters, such as those used for cleaning blast furnace gases, are provided with means, responsive to the pressure drop across the bags, for controlling an electric circuit to give an indication to an attendant or cause a cleaning operation to be performed' on the bags. As shown in Fig. 1, a flexible diaphragm 1 in a chamber 2, connected by pipes. 3, 4 to either side of a filter, turns a lever 8 and causes mercury in a tube 10 to close an electric circuit, which, by relay, closes a switch 21, Fig. 2, in the circuit 20 of a coil 19 operating a contactor 11. The latter closes a main circuit 13, 14, which by leads 15 .. 18 is connected to motors each of which operates the cleansing devices of a group of filters. The motors instead of being connected in the main circuit may be connected in circuits which are closed successively by a conductor on a plate 12, rotated through worm and bevel gearing by a motor 22 in the circuit 20. The operating motors are preferably connected with valves which control cleansing operations in such a manner that the positions of the valves are altered as required without reversal of the motors, which are merely started and stopped. The motors may operate devices which shake the filter bags to detach dust therefrom. The shaking is preferably associated with a reversal of gas pressure through the filter. Fig. 4 shows a rotary valve 28 which has a connection 30 to the discharge side of the filter and connections 29, 31. to suction and to the atmosphere respectively. The valve is rotated by a motor (not shown) the circuit of which is closed by contacts'on the member 11, Fig. 2. The filter bags are cleansed when the position of the valve allows of communication between the connections 30, 31. Contacts 34 which can be opened by a cam 33 on the valve spindle ensure that the circuit of the operating motor for the valve is kept closed until the valve has returned to its normal position.

A metal working press is substantially the same as that described in the parent Specification but incorporates modifications in which a finger piece secured to the ram is manually slidable relative to the housing to advance the ram and also incorporates an improved ram return mechanism. A finger piece 54 is slidably mounted on the housing 2 and secured to the lower end of the ram 10. Upward movement of the finger raises the ram 10 causing the crimping dies to engage a female portion 23 and partially straighten the toggle linkages prior to the power operation of the tool. The return mechanism comprises a pair of parallel plates 61 positioned adjacent the outer sides of the pairs of links, each plate having a hook 64, notch 65, toe 66 and an extension 67. The plates are biased downwardly by springs 68 and the notches 65 engage pins 69 secured to the links 42. A pair of latch plates 70 are positioned on the outer sides of the plates 61 and pivoted at 27, each plate having a slot 72 which slidably engages the pivot pins 33, 45 and a shoulder 73. In operation the plates 70 are lifted by the ram 10 and the plates 61 lifted by the pins 69 against the springs 68 which also bias their hooks 64 to engage the shoulders 73 on the plates 70. On completion of the working stroke the cam block is lowered with the piston causing the pins 69 to disengage the notched 65 thus allowing the springs 68 to retract the plates 61, 70 and lower the ram 10. A cam face 67<SP>1</SP> on the plates 61 engages the pins 45 and moves the plates laterally to disengage the hooks 64 from the shoulders 73 and allow the plates 61 to further retract until their toes 66 engage the face of a separator plate 40 which tilts the plates to ensure that disengagement of the plates is effected.

Abstract: 1451018 Coiling barbed wire KELLER & KNAPPICH AUGSBURG ZWEIGNIEDERLASSUNG DER INDUSTRIE - WERKE KARLSRUHE AUGSBERG AG 23 Aug 1974 [28 Sept 1973] 37169/74 Heading B3E Barbed wire is coiled into helical form on a rotating core, and each turn of the helix is secured to its predecessor at points circumferentially offset from the corresponding points at which that predecessor is secured to its predecessor, so that the helix can be expanded along its axis. In Fig. 5, strip from reel 17 is formed into channel section by rolls 18, wire from reel 19 is laid in the channel, and the channel is clenched over the wire by rolls 22. The strip is of such configuration that the result is a barbed wire as shown in Fig. 1. This wire is then wound on to ribs 27 circumferentially spaced on the rotating core so that the ribs enter the spaces between the barbs. Spaced rib pairs 27<SP>1</SP> lie opposite five fastener devices 28 on a turntable 29, which clamp adjacent turns of the coil together by clips 15 as in Fig. 3. Fig. 4 shows the clamping pattern for ten turns of the helix, adjacent turns being secured at stations I, III and V, and stations II and IV on alternate turns. A fastener device is shown in Fig. 9, and comprises a double acting pneumatic piston and cylinder 38, 39, the hollow piston-rod 37 containing a sliding rod 40 supporting a head 41. Clamping levers 30, 31 are pivoted on the head at 32 and connected by toggle links 34 to rod 37. A bifurcated jaw pair 44 (one shown) is slidably mounted on head 41 and biased to the left as seen in Fig. 9. The operative stroke of the piston is in three phases. In the first phase, the rod 37 and all its supports moves to the left so that jaws 44 engage and suitably position two consecutive turns of the helix. The jaws then halt, and head 41 continues to advance so that a clip, which has been fed laterally to be held between recesses 130 in levers 30, passes over the two turns. The head 41 is then halted, and the remaining stroke of rod 47 pivots the levers by links 34 to clamp the clip. Further devices 55, Fig. 5, at each clamping station have pivoted fingers which assist in locating the turns correctly.

Abstract: 505,352. Valve generating circuits. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE. Dec. 23, 1938, No. 37526. Convention date, Dec. 23, 1937. [Class 40 (v)] Two blocking oscillators, or multi-vibrators, which are arranged to operate at different sub-multiples of a control frequency are interconnected so that impulses at a frequency equal to the greatest common sub-multiple are produced across a common output' impedance. The essential parts of the circuits of two blocking oscillators are indicated in Fig. 6. As shown, the two valves are pentodes, although a single valve with electrodes as indicated in Fig. 9, could be used, the screens of the valves being used as the oscillator anodes and the control,and suppressor grids being cross connected. The oscillators are arranged to oscillate at different sub-multiples of the main frequency. With this arrangement an impulse is produced across the common anode impedance 10, Fig. 6, only when the two oscillators are in step. For example, if the synchronizing frequency is S and the two circuits oscillate at S/n and S/m respectively, the frequency of the pulses across 10 is S/n Î m . The conducting periods of the oscillators is kept short to prevent intermediate pulses due to overlap. Synchronizing pulses may be applied across an impedance 6 in the grid lead as indicated in Fig. 3, or across 6<1> in the cathode lead as shown in Fig. 4.
