Filed: 1942-11-05
Abstract: 586,274. Heat-exchangers. EYRE, D. Nov. 5, 1942, No. 15646. [Class 64 (iii)] [Also in Group XXVI] In a gas turbine, such as described in Specification 585,330, [Group XXVI], in which air from the compressor passes into rotating chambers 31 in the burner assembly carried by the disc 40, and mixes with fuel thrown out by the rotating burners 46, part of the air is diverted into a chamber 85 and thence passes inwardly through a rotating heat-exchanger 48 giving up heat to fuel moving outwardly through the heatexchanger which comprises close-fitting spiral tubes 58 each formed of a flat plate 63 and a corrugated plate 64, Fig. 7. The air spaces between the tubes 58 are closed at the sides by the discs 40, 48 between which the tubes are clamped. The fuel enters by passages 52, 54, passes through non-return valves 56 in stationary blocks 55, and is received in a channel 51 in the rotating assembly from which it passes to the inner end pieces 66. Thence, it passes through the spiral tubes 58 and through perforations 80 into the hollow bolts 79, and is extracted at the end pieces 73 and led to the burners 46. The end pieces 73 form scoops which force the air to travel inwardly in the spaces between the outsides of the corrugated plates 64 and flat plates 63 of adjacent tubes.

Title: Improvements in or relating to the control of fermentation, particularly of brewers'wort
IPC: C12C11/00
Filed: 1930-05-24
Abstract: In the production of beer or the like, fermentation is regulated by varying a pressure or vacuum to which the wort is subjected, so that rate of purging of the yeast is controlled. The fermentation vats may be themselves constructed so as to withstand the internal or external pressure, or may be contained in a masonry or other outer casing, or in a room in which pressure or vacuum is produced.  A connection from an outer vessel to a vacuum main may lead from the bottom of the vessel and be provided with means for detecting leakage.
Patent GB-599626-A (GB)
Title: Improvements in or relating to the manufacture of purified penicillin
IPC: C07D499/16
Filed: 1945-06-25
Abstract: Crude penicillin preparations obtained from solutions resulting from both surface and submerged cultures of any penicillin-producing mould are purified by chromatographing an aqueous solution of an alkaline earth metal (including magnesium) salt of penicillin, using aluminium oxide as adsorbent, and isolating the product, optionally in crystalline form, from the percolate either in free form or as a salt.  The additional step of chromatographing free penicillin in an organic solvent by passing through a column of magnesium silicate, e.g. magnesium trisilicate, may also be carried out before or after the main process, yielding a purer product than is obtainable by the single step.  The highly-purified sodium penicillin, obtained by using these two procedures, may be crystallized from anhydrous organic solvents such as ketones or alcohols, e.g. methanolisopropanol mixtures.  In examples: (1) magnesium penicillin in aqueous solution is chromatographed on water-washed aluminium oxide, and the percolate is collected in three fractions, acidified at 0 DEG  C. to pH3 with 10 per cent phosphoric acid and extracted with butyl acetate (or isopropyl or amyl acetate, or chloroform or ether), prior to treating with 0.1N aqueous sodium hydroxide or dilute sodium carbonate or bicarbonate to isolate the sodium salt; alternatively, corresponding alkali or alkaline-earth metal salts are isolated by substituting ammonium, lithium or barium hydroxides, calcium, strontium or barium carbonates, magnesium oxide, or similar alkali or alkaline-earth hydroxides, oxides, carbonates or bicarbonates; (2) the process of (1) is applied to magnesium penicillin of different potency, two fractions being collected and adjusted to pH 6.5 to isolate sodium penicillin; (3) crude calcium penicillin is chromatographed as in (1) and the butyl acetate extract is treated with 0.05N aqueous sodium hydroxide to isolate sodium penicillin; (4) crude penicillin in butyl acetate, isolated from submerged cultures of Penicillium notatum is chromatographed on magnesium trisilicate, eluted with a phosphate buffer of pH 7.5 and converted to the barium salt, a 20 per cent aqueous solution of which is chromatographed on aluminium oxide and further treated as in (1), to obtain a highly-active sodium salt, which is crystallized from methanol-isopropanol; (7) the entire procedure of (6), applied to barium penicillin, derived from surface cultures of P. notatum, is used in reverse sequence to isolate crystalline sodium penicillin. The Specification as open to inspection under Sect. 91 comprises also the single step of chromatographing free penicillin in an organic solvent by passing it through a column of magnesium silicate and recovering penicillin from the adsorbent.  In examples: (a) penicillin dissolved in butyl acetate is adsorbed on magnesium trisilicate eluted with a phosphate buffer (pH 7.5); (b) a similar process is carried out using a solution of penicillin in ether.  This subject-matter does not appear in the Specification as accepted.

Title: Polymer moulding compositions
Inventor: CLARK KEITH JASPER
IPC: C08F10/00
Filed: 1965-04-15
Abstract: A solid polymer moulding composition comprising a copolymer of propylene comprises at least 55% by weight of propylene monomer units, monomer units of a second component which is a linear 1-olefine having 4 to 18 carbon atoms in an amount up to 35% by weight, and having dispersed throughout the composition units of a third component which is an alpha-olefine, which as a homopolymer has a crystalline melting point above 180 DEG  C., and is present in the composition in an amount of up to 10% by weight.  The composition is made by bringing propylene, the second and third components into contact with an alpha-olefin polymerization catalyst, preferably stereospecific.  The catalyst is preferably "pretreated" i.e. a catalyst which has been treated with one or more monomers at high catalyst concentration and subsequently used at lower catalyst concentration for a further polymerization.  The third component may be polymerized before or subsequent to the polymerization of the other monomers.  The catalyst is preferably TiCl3 activated by an organoaluminium compound.  The TiCl3 may be obtained by reducing TiCl4 with an aluminium alkyl sesquichloride.  The second monomer may be butene-1, octene-1, or ecened-1. The third component may be 3-methyl-pentene-1, 4,4-dimethylpentene-1, vinylcyclohexane, or 3-methyl-butene-1.  The polymeric compositions may be recovered from the polymerization reaction by conventional techniques. The compositions may be compounded with heat and light stabilizers, fillers, antioxidants, antistatic agents, carbon black, pigments, flame retardant materials and other polymers such as high or low density polythene, polypropylene and butyl rubber.

Title: Improvements in electric insulators

Filed: 1928-06-05
Abstract: 310,222. Porzellanfabrik P. Rosenthal & Co., Akt.-Ges., and Schmidt, W. June 5, 1928. Casting processes.- In an electric insulator of the type in which the cap or pin of the insulator is secured to the body part by means of a metal filling, a colloidal coating, such as a suspension of alumina in water is applied to the insulator body before the molten metal is poured in, so as to avoid stresses in the insulator bodv due to the shrinkage of the metal filling when cool. When the molten metal is applied, the alumina suspension gives off water, decreasing in volume, and, it is stated, owing to its elactsicity, allows the filling to shrink without strain. In a modified construction, a layer of soft metal may be applied to the body part by spraying. If the soft metal is of higher melting point than the filling, it will act as a cushion ; if of lower melting point, it will melt during the cooling of the filling and thus make room for shrinkage of the filling. In the embodiment, a layer Z of the alumina suspension is applied to the head P of an insulator body and the cap A placed in position. The insulator is then inverted and lead alloy poured into the space between the cap and the insulator.
