Abstract: 1,075,463. Moulding foam material. E. ANDERSEN. June 15, 1964 [June 14, 1963], No. 24704/64. Heading B5A. [Also in Division F2] Foam material is cast in the space between an inner pipe, e.g. of steel and an outer protective pipe, e.g. of plastics material, the pipes being in substantially vertical position. The foam may be polyurethane containing suitable foaming and setting agents. Initially a small amount of foam material is cast and allowed to set or partially set to form a plug. Prior to casting a lubricant such as a mixture of stearates with oil or alcohol may be applied to the surfaces of the pipes which will contact the foam or alternatively a lubricant powder may be applied to the annular space which powder is agitated during the foam casting operation by a pneumatic hose creating air flow, the nozzle of the hose being raised so that it is always just above the surface of the rising foam. The compounds pipes are joined together by welding projecting ends of the inner (steel) pipe, shells of poly-urethane foam material glued thereon, and a heat-shrinkable P.V.C. pipe collar pushed over the whole joint and heated.

Void [Published under Sect. 91 of the Acts]. Addition to 366,505. Drawings to Specification. [Class 40 (ii).] The process of producing a record of the variable width type, described in the parent Specification, is modified by giving the film a supplementary exposure, in addition to the actual sound-recording exposure, so that the resultant exposure both for the " core " and for the fringe of the sound trace is always above the value represented at the lower bend of the photographic characteristic curve. The additional exposure, which may be of constant or variable intensity, may be made by the sound-recording lamp or by a separate lamp with the use of a separate slit, and it may occur either before, simultaneously with, or after the sound recording. The supplementary exposure may also be given during the production of a positive by copying. An apparatus for carrying out the process is described and illustrated, and is the same as that described in Specification 384,006.

Title: Process for producing volatile hydrocarbons from hydrocarbonaceous solids
IPC: C10B49/06
Filed: 1946-08-26
Abstract: 617,284. Distilling solid carbonaceous materials.' UNIVERSAL OIL PRODUCTS CO. Aug. 26, 1946, No. 25412. Convention date, March 18, 1944. [Class 55 (i)] In a process for the distillation of hydro-carbonaecous solids wherein these are passed downwardly through an externally unheated retort, whilst a pre-heated stream of hydrocarbon fluid passes upwardly in direct contact with the solids the pre-heating being effected by indirect contact of the stream with the combustion products from the burning of the coke-like residue from the retort, the distillation products are fractionated and after withdrawing at least one of the fractions to storage the stream is constituted by at least one other of the fractions, which is heated and recirculated to the retort. The charging material which may consist of oil shale, tar sands, coal or the like is fed from hopper 1 to the retort 4 to form a downwardly moving bed 5. The volatiles from bed 5 are driven off by direct contact with a stream of heated hydrocarbon fluid introduced at different levels of the retort. The coke-like material leaving the retort falls on to a moving grate 11 in a combustion zone 9, to be carried and burnt in a thin layer 10 over pre-heated air inlets 24. The combustion products serve to heat the coils 64 and 57 and finally escape by stack 26. Additional shale &c., may be supplied from hopper 81 to augment the supply of heat from fuel layer 10. Vapours from retort 4 pass to a fractionator 31, the lighter fractions and gases passing to the condenser 33 and separator 35, wherefrom liquid and gaseous distillates may be withdrawn to storage, through valves 37 and 39. Selected fractions may also be withdrawn from appropriate levels in the fractionator. Part of the gaseous and liquid distillates may be taken through lines 52 and 58 to pumps 54 and 60, and into heating coils 57 and 64, thereby attaining a temperature of 510-650 C., and a pressure of about 68 atmospheres and thence to the retort, producing a temperature in its lower part of 480 - 595 C. All or part of the heavier fractions from the fractionator 31 are directed through line 42 to a pump 44, thence to a coil 50 in a suitable furnace 51, there attaining a temperature of 425 - 510 C. and a pressure of between 7 and 35 atmospheres, and then into the retort 4 at different levels, producing a temperature therein of 400 - 455 C. Volatile matter is thus distilled from the bed of material and the higher temperature at the lower part causes coking of the residual mass. To start the process, a relatively heavy oil is supplied through line 67 to the coil 50. This external supply may be maintained during the process if desired, with or without an external supply of light oils or gas through line 72 and pump 74 to coils 57 and 64. Specification 484,050 is referred to.
