Title: Improvements in liquid fuel burners with a rotary and blown flame
IPC: F23D11/08
Filed: 1937-10-11
Abstract: 501,938. Liquid-fuel burners. HOURWITZ, A. Oct. 11, 1937, No. 27583. Convention date, Oct. 13, 1936. [Classes. 75 (i) and 75 (iii)] [Also in Group XVIII] A liquid-fuel burner comprises a rotating atomizer cup 1 carried by the hollow shaft 2 of a turbine, hydraulic or electric motor 3 which shaft extends at its lower end into a constant level fuel receptacle 7 so that the fuel rises by centrifugal force to the cup and is flung off to mix and burn with air supplied by a fan 8 on the shaft 2. The motor 3 and receptacle 7 are secured to a cylindrical casing 4 attached to the apparatus to be heated. The atomizer cup is surrounded by a burner cup 16 supported by a throat 14 attached to an apertured frame 9 in the casing 4. The burner cup is formed with holes 16a having upturned edges. An insulated heating resistance 13 is mounted on the central portion 10 of tho frame 9. At starting the spray from the cup I is caught by the cup 16 and returned through a drain 11 to the receptacle 7 until the resistance 13 becomes sufficiently hot to vaporize and ignite the fuel. The shaft 2 is fitted with an apertured plug 6 at its lower end and may be of stepped or frusto-conical form with or without internal ribs. Alternatively its internal surface may be paraboloidal. The fuel level around the shaft 2 may be controlled by a float or by closing the receptacle with a cover 7 having a depending sleeve 7b formed with an air inlet 7c. The flame may be regulated by varying the speed of the motor or by varying the fuel supply either by a needle valve at the apertured plug 6 or by varying the fuel level around the shaft 2. Fig. 2 shows an arrangernent of fuel receptacle in which the fuel level in the sleeve 7b is rendered variable by providing a second sleeve 7d having an open top and fitted with an adjustable inverted tube 19 enclosing one leg of a U-tube 22, the other leg of which opens above the fuel level in the receptacle.

Title: Separation of inhomogenous particles from pulverulent silica catalyst carriers for palladium catalysts for reactions in a fluidized bed in liquid phase
IPC: C07C53/16
Filed: 1975-07-02
Abstract: 1503642 Catalytic reactions HOECHST AG 2 July 1975 [6 July 1974] 27838/75 Heading B1F In the process for carrying out heterogeneous catalytic reactions continuously in liquid phase as disclosed in specification 1363245. the catalyst is a palladium catalyst deposited on a silica carrier which is obtained by contacting a mixture of pulverulent silica carrier and in homogeneous silica particles with upward flowing water to free the carrier from the silica particles. The expression "inhomogeneous silica particles" is defined as meaning silica particles having a porosity which differs substantially from that of the other particles in the mixture. Such particles consist mainly of the fines present in the mixture. The silica carrier has a particle size of 20-300 microns and the catalyst may be produced by impregnating the carrier with a palladium salt which is subsequently reduced to metallic palladium in accordance with the process described in Specification 1403293.

Title: Distributor for telegraphy or the like
IPC: H04L5/24
Filed: 1930-09-18
Abstract: 362,044. Multiplex telegraphy. STANDARD TELEPHONES & CABLES, Ltd. and SANDEMAN, E. K., Columbia House, Aldwych, London. Sept. 18, 1930, No. 27890. [Classes 40 (iii) and 40 (v).] In a distributer for telegraphy or television, successive time elements for the transmission or reception of signal impulses are measured off or determined by connections between sections of a delay network. The distributer includes a series of valves which are normally paralysed and to which is applied a wave of a form so arranged that for any particular time element, only a single appropriate path is available for the transmission of a signal impulse, and the same wave, applied through the various sections of the delay network, causes the valves to be operative in succession. The contacts of the relays R1, R2, R3, .. are set up according to the code elements to be transmitted and an operating wave of the form shown by curve C, Fig. 2, is applied through the sections D1, D2, D3 .. of a delay network. The valves V1, V2, V3 .. are normally paralysed, but the wave portion of positive amplitude actuates a valve so that in successive time intervals of p (dependent on the number of relays R1, R2, R3 .. and the time for setting them up) the valves V1, V2, V3 .. are in an operative condition and alternating current from a source G will be sent to the line L corresponding to the operated contacts of the relays R1, R2, ... At the receiving distributer, Fig. 5, the incoming impulses are applied to the valves V1, V2, V3 .. rendered operative in succession by the application of a wave similar to that shown by curve C, Fig. 2, through the sections D1, D2, .. of a delay network. When a received signal impulse is applied to the appropriate operating valve, the corresponding T relay operates and locks up over its upper contact. The relay is released by the operation of a slow acting relay S, Fig. 6, energized after the signal element has been effective in the printer. The signals sent to the line may be converted to direct current impulses by the inclusion of a rectifying device. The operating wave C, Fig. 2, may be obtained by passing A.C. current of a frequency corresponding to that of the waves A, B into amplifiers SA1, SA2 and through a phase-distorting network P into wavesquaring devices SQ1, SQ2 and a through final amplifier SA3. The sections of the delay networks D1, D2, D3 .. may comprise one or more networks of the type shown in Fig. 3. A delay which is not an integral multiple of that given by a single typical network may be obtained by the arrangement shown in Fig. 4. Resistances 101, 1011 of a high value in comparison with the characteristic impedance of the networks 41, 42, 43 are bridged at variable tapping points 104, 105 by a high impedance amplifier, such as the grid circuit of a valve and by adjustment of the tappings 104, 105 a delay equal to a fraction of the delay of the network 42 may be obtained.

Title: Improvements in and relating to hoisting apparatus
IPC: B66C7/00
Filed: 1938-09-24
Abstract: 503,394. Winches. STORK & CO.'S APPARATENFABRIEK N.V., GEB. Sept. 24, 1938, No. 27910. Convention date, Nov. 30, 937. [Class 78 (v)] A hoisting-apparatus combined with tipping means has two drums 9, 10 on which is wound a cable 34 the ends of which are attached each to one of the drums. The bight of the cable passes round a pulley 35 geared by chains 42 to a shaft 45 carrying two grooved sheaves 50. Endless chains 52 riding over these sheaves encircle also sheaves 54 on the ends of a container 55, so that rotation of the drums 9, 10 in opposite directions will result in a travel of the cable 34 from one to the other, with consequent turning of the pulley 35 and sheaves 50, resulting in tilting of the container 55. The drums 9, 10 are driven by two motors which operate respectively worms 24 and 32. The worm 24 meshes with a wheel 23 which carries differential pinions gearing with sun wheels 21, 22 fixed respectively to toothed wheels 18, 19 meshing with pinions 16, 17 attached coaxially respectively to wheels 13, 14 gearing with pinions 11, 12 on the drums 9, 10. Positive rotation of the worm 24 thus produces equal progression in the same direction of the drums 9 and 10, with equal winding-on or winding-off of the cable 34 and simple raising or lowering of the load. The worm 32 meshes with a wheel 31 carrying differential pinions engaging sun-wheels fixed respectively to pinions 26, 28. The pinion 26 gears directly with pinion 16, but the pinion 28 gears with the pinion 31 through an intermediate wheel 27. Positive rotation of the worm 32 thus effects rotation of the drums 9, 10 in opposite directions, with consequent tipping of the container 55. The differentials permit one of the'worms 24, 32 to be stationary while the other drives, but both may be driven together. giving lifting or lowering simultaneously with tipping. Idle sheaves 36, 37 guide the cable 34, and a motor 7 traverses the hoist along a runway 6. The worm 32 is self-braking, but the worm 24 is preferably not, but is fitted with an electromagnetic brake automatically applied and released when its motor stops and starts.
