In a process of producing combustible gases from normally liquid hydrocarbons having a viscosity not less than 45 s.s.o. at 210‹ F. the hydrocarbons are contacted with a fluidized bed of finely divided coke-covered particles in a coking zone 1 at a temperature not less than 1400‹ F. and a pressure of from 0-50 p.s.i.g., finely divided particles being circulated to and from a heating zone 8 by lines 7 and 4 respectively and wherein the particles are contacted with steam and pure oxygen and heated to a temperature above the temperature of the coking zone, gaseous products being withdrawn from zones 1 and 8 by lines 5 and 12 and mixed. The hydrocarbon may be a petroleum hydrocarbon, e.g. still bottoms, a residual oil or a reduced crude oil, and the oxygen used in zone 8 contains not more than 4 per cent and preferably not more than 1 per cent of impurities by volume. The residence time of the hydrocarbons in the coking zone 1 is from 0.1-2 secs. and the temperature is not more than 2200‹ F. and is preferably between 1800-2200‹ F. and the temperature in the heating zone 8 is from 100-500‹ F. and preferably 200-400‹ F. higher than the temperature in the coking zone.

Abstract: 1,091,725. Sheet forming. FORGROVE MACHINERY CO. Ltd. July 4, 1966 [Aug. 11, 1965], No. 34435/65. Heading B5A. In a forming process a sheet E of thermoplastic material is clamped over a female mould G and blown into contact with a heater platen F. Simultaneously a piston-operated plunger D is raised into contact or near contact with the sheet. After sufficient heating compressed air is introduced through holes T in the heating platen to blow the sheet into the mould, the plunger being forced back to its lower position by the sheet against a controlled air pressure in space H. Alternatively the plunger may move down independently of the blowing pressure and may be mechanically, pneumatically or hydraulically operated. The sheet may alternatively be vacuum formed.

In one embodiment the primary radiator 1 is in the form of an ovoid having a vertical axis of symmetry surrounded by an oblique angled cone and merging at its base with the inner conductor of a coaxial feeder 4, the outer conductor of which connects with a ground plane 2 which may be raised, 3, in the vicinity of the base to improve the radiation pattern at higher frequencies. Three thick barlike reflectors 5, 6, 7, of decreasing height are provided at different distances from the axis of the radiator to form the reflector system and it is stated that for such a radiator the distance from the feed point along the axis of the radiator to the effective emission area decreases with increasing frequency so that in turn the reflectors 5, 6 and 7, become effective. In another embodiment two such radiators are used as a centre fed dipole and these, together with dipole reflectors are disposed at the focus of a parabolic reflector, Fig. 4 (not shown). In other embodiments each reflector of the reflector system may take the form of two planes intersecting in a line parallel to the axis of the radiator, Fig. 3 (not shown), and an array of parallel radiators employing such reflectors, Fig. 5 (not shown); alternatively the reflectors may be curved in one plane. The arrangement shown in Fig. 1 is stated to be effective over a five to one frequency band.

IPC: B01J19/02
Filed: 1957-11-08
Abstract: The impermeability of a graphite article, e.g. a rod or tube, is increased by deposition of carbon or graphite in its pores from the vapour state in an atmosphere of helium or argon.  Graphite may be vaporized at 3700 DEG C. and deposited at 3000 DEG C.  Vaporization may be effected by <PICT:0900568/III/1> <PICT:0900568/III/2> resistance or induction heating.  Graphite may be vaporized at the inner part of a graphite rod and condensed at the outer part. According to Fig. 1 (not shown) a resistance heated rod is surrounded with a clearance by lagging comprising an inner graphite tube and an outer water cooled stainless steel jacket, the space between the graphite tube and steel jacket being packed with powdered or granular graphite.  The lagging has a pyrometer sighting tube.  The inner graphite tube may be heated other than by radiation from the rod.  As shown in Figs. 2 and 3 a resistance heated rod 1 is surrounded by seven internally water cooled polished aluminium tubes 11 in a stainless steel vessel 19.  Tubes 11 rotate in a reciprocatory manner and are kept clean by continously rotating brushes 16.  Two of the tubes 11 are grooved to provide a pyrometer sighting hole (Fig. 4, not shown).

Abstract: 377,085. Heating buildings &c. RUTHSACCUMULATOR AKTIEBOLAG, 1A, Eriksbergsgatan, Stockholm. Dec. 22, 1931, No. 35474. Convention date, Dec. 24, 1930. [Class 64 (ii).] A hot - water heating system comprises a large boiler 1, a pump 4, and an auxiliary container 7 adapted to receive the relatively cold liquid from the radiators 2 when there is an abnormally large consumption of heat. For this purpose a return valve 6 to the boiler tends to close when the pressure within the boiler falls, and the water is forced into the container 7, which has a capacity equal to the difference between the highest and lowest volume of water in the boiler. A rise of pressure within the boiler opens the valve, and the water from the container returns to the boiler. The steam spaces of the container and boiler also communicate through a pipe 8, which serves as an overflow pipe for all the water when the return valve 6 is closed. Several boilers may have a common auxiliary container in the return pipe before it branches to the boilers. The container has an overflow pipe with a number of branches equal to the number of boilers, the branches having valves and entering the container at different heights.

Abstract: 437,697. Fibrous - cement tubes. SOC. ANON. STABILIMENTI DI DALMINE, Dalmine, Bergamo, Italy. Dec. 11, 1934, No. 35607. Convention date, March 2. [Class 99 (ii)] A tube made by winding helically on to a rotating and axially-moving core successive layers of fibrous-cement, the fibrous-cement being fed and applied to the core by a plurality of belts, is provided with an integral end socket while it is still in a moist condition. A core a, Figs. 2 and 4, having an enlargement a<1> may be used, in which case the body portion b of the tube, with conical ends b<1>, is first formed, after which the core and tube are transferred to a socket-forming machine which is similar to the body-forming machine and includes one or more relatively narrow feed belts. These belts are located and the inclination of the rollers c, d carrying them is adjusted in such a manner that a wound-on socket c, starting from one end b<1>, is formed. Preferably the turns of the socket are wound with a reduced pitch so that each turn partly overlaps the preceding turn. Alternatively a wholly cylindrical core is used, and after the body portion of the tube is formed operation of all the belts except one is discontinued and the inclination of the remaining belt and its roller c, Fig. 5, reduced so as to apply fibrouscement with a very small pitch. A cylindrical end el, of length approximately equal to the width of the feed belt, is thus formed on the tube which, after setting, is machined to socket shape. Specifications 321,471, [Class 99 (ii)], 391,909, and 416,060, [Group V], are referred to.

Fatty substances may be eliminated from the protein by treatment with steam or an organic solvent, e.g. trichloroethylene, perchloroethylene, acetone or a chloroform-methanol mixture. Numerous sources of the proteins are listed and in a specific example waste bits of limed skin are used. The polymers containing hydroxyl groups may be polyethers or polyesters.
