Abstract: 957,465. Extruding. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Nov. 13, 1962 [Nov. 20, 1961], No. 41371/61. Heading B3P. A metal tube extrusion press has a mandrel 8 which moves axially through the die during extrusion when it is supported at its outer end to prevent any deflection from the axis. A reduced end nose 19 on the mandrel engages within a sleeve 20 which is supported initially by a frangible pin 22. The latter is sheared by pressure applied to the mandrel head 9 by an hydraulic ram 43, and allows the sleeve 20 to move downwardly in a bore 17 of the die and thus guide the mandrel.

Patent GB-1121095-A (GB)
Title: A process for producting dextrose from starchy materials
IPC: C12P19/20
Filed: 1965-09-29
Abstract: Dextrose is produced from starch or partially hydrolysed starch by hydrolysis with a glucoamylase-containing fungal enzyme, at least the initial stage of the hydrolysis being effected at a pH below 3, provided that when the initial stage of the hydrolysis is effected at a pH of 1.5 or below, the pH is adjusted to above 3 during the latter stage of the hydrolysis. It is preferred to use partially converted starch having a reduced viscosity when dispersed in water.  Acid or enzymic hydrolysis of starch to obtain a substrate having a solids concentration of 20-45% provides a suitably converted starch.  Lower sugars can be used in the process.  An unpurified fungal enzyme preparation containing other enzymes in addition to glucoamylase may be used.  The hydrolysis is preferably conducted at 35-60 DEG  C. Examples relate to starch hydrolysis at constant low pH values and to hydrolysis at initial low pH values with subsequent increase of pH to, e.g. 4.

Patent GB-1563324-A (GB)
Title: Apparatus for moulding articles from foamable plastics material
IPC: B29C44/58
Filed: 1976-10-07
Abstract: In the process, foamable plastic granules, which may already be prefoamed, are foamed in a mould (1) under the effect of steam on heated mould walls. The moulding is stabilised by cooling the mould walls and is taken out of the mould. In order to ensure uniform and complete foaming, the steam is passed through the granules. To this end the steam is allowed to flow into the mould (1) via steam inlet openings (12). Since the total cross-section of the steam outlet openings (11) is smaller than that of the steam inlet openings (12), a steam pressure builds up in the mould so that the steam is distributed over the entire mould cavity. This effect is reinforced by a buffer volume of a distribution chamber (9) and/or of a collection chamber (5). Valves (6, 10) can be provided to control the steam flow. Vacuum pumps (13) can also be connected via valves (14) to the mould cavity. <IMAGE>

To prevent oxidation of the dry-charged negative electrodes of a lead-acid accumulator during the shelf-life period before the acid is introduced they are provided with a coating consisting of a silicone, containing an anionactive emulsifying agent. The emulsifying agent enables the sulphuric acid to re-emulsify the silicone whereby the coating is quickly removed after introduction of the acid and the accumulator is immediately ready for use even at temperatures below 0 C. A preferred coating consists of a methyl-silicone resin containing an emulsifying agent of the fatty alcoholic polyglycol ether type. The dry-charged negative electrodes are coated by forming an aqueous emulsion of the coating material and dipping the electrodes in the emulsion.

Abstract: 1,181,989. Separating gaseous hydrocarbons. CONTINENTAL OIL. CO. 20 Sept., 1967 [9 Dec., 1966], No. 32870/67. Heading B1L. [Also in Division C5] Ethane and ethylene are removed from hydrocarbon feed streams 1, e.g. natural gas, by passing the feed to and through hot desorbed adsorption bed 4, whereby the bed is cooled and the effluent gas, from which ethane and ethylene has been removed until the bed is saturated, is heated. Displaced gas passes by lines 10, 14, 16 and 31, blower 22, line 23, heat exchanger 27, line 23, heater 24 (which may be bypassed), and lines 25, 7 and 9 to bed 5, displacing the gas therein through lines 11, 13 and 26 to residue. While bed 4 is in the adsorption phase, hot gas is passed from heater 24, through lines 25, 7 and 9 to bed 5 to desorb sorbate, while effluent from bed 4 passes to residue through lines 12 and 26. Desorbate from bed 5 circulates in a closed path through lines 11, 15, 31, blower 22, line 23, heater 24 and thence back as described above to bed 5 until the pressure in the closed circuit rises to a predetermined level, when the circulating product gas is bled off through lines 32 and 33. When bed 4 is saturated, the functions of beds 4 and 5 are interchanged. If the product is condensable, the circuit is modified to include a cooler-condenser and separator (see Fig. 2, not shown) in the closed desorption circuit before the circulating product is reheated and passed back to the bed being desorbed.

Title: Method of manufacturing bodines of foamed plastic
IPC: C08J9/236
Filed: 1963-10-31
Abstract: Foamed plastic material is obtained by heating granules of synthetic plastic material containing an expanding agent in two or three expanding steps so that the mass of granules is brought to a density which is substantially lower than the desired density of the product and then reducing the mass of the expanded granules in a subsequent interconnection step by displacing the granules relatively to one another and/or by compression so as to fill the interspaces between adjacent granules to a substantial degree, whereby the density of the coherent body is increased.  Binding agents such as polyvinyl acetate dissolved in ethyl alcohol or phenol, urea, polyurethane or epoxy resins may be used, or the granules may be fused by a high-frequency current.  The expanded granules may be interconnected by compression between the endless belts of the apparatus described in Division B5.
