Title: Improvements relating to linear polyesters
IPC: B29C55/14
Filed: 1956-01-30
Abstract: A crystallizable linear copolyester is made by reacting a glycol of formula HO(CH2)nOH, where n is 2-10, from 5 to 35% by weight, based on the total weight of the acid components calculated as the acid form, of an acid component in the form of isophthalic acid or a lower alkyl ester thereof and 95 to 65% of an acid component in the form of terephthalic acid or a lower alkyl ester thereof, under ester-forming or ester-interchange conditions to form a mixture of glycol esters and polymerizing this mixture in presence of antimony trioxide. As ester-interchange catalyst there may be used litharge, lithium hydride or a mixture of lithium hydride and zinc acetate.  The copolyesters may be converted into films, filaments, fibres, ribbon and tubing.  In examples copolyesters were made by heating a mixture of dimethyl terephthalate, dimethyl isophthalate and ethylene glycol in presence of lithium hydride and zinc acetate dihydrate until evolution of methanol ceased, adding antimony oxide and triphenyl phosphate and heating under reduced pressure p  and finally annealing the resulting copolyester at 115-140 DEG  C. under nitrogen pressure. Specification 766,290 also is referred to.

Title: Acetoxymethyl benzylpenicillinate
Inventor: JANSEN ALEXANDER BERTUS ARNOLD
IPC: C07D499/32
Filed: 1963-05-30
Abstract: The invention relates to acetoxymethylbenzylpenicillin, which is effective orally.  Acetoxymethyl benzylpenicillin is prepared by condensing acetoxymethyl halide e.g. bromide with benzyl penicillin, especially in the form of a salt thereof, in the presence of a solvent such as dimethyl formamide.  It may be crystallized from chloroform or isopropyl alcohol.  Acetoxymethyl halides are prepared by heating an acetyl halide with paraformaldehyde in the presence of anhydrous zinc chloride and recovering the acetoxymethyl halide by distillation.  Pharmaceutical compositions for oral use comprise acetoxymethyl benzylpenicillin and a carrier.  The composition may take the form of powders, tablets, granules, capsules, troches, cachets, solutions, suspensions and emulsions. Other penicillins may be present.  On oral administration, sustained high blood levels of penicillin are obtained.

Abstract: 1533444 Tubular heat exchangers CURTISS WRIGHT CORP 27 May 1976 [29 May 1975] 21987/76 Heading F4S One or more heat exchange conduits 16 in the form of a flattened helix with straight portions interconnected by bends as shown in Fig. 9, and of polygonal (e.g. rectangular) cross-section, are disposed in a shell (such as the shell 12A, Fig. 4) and a heat exchange fluid passes through the shell and over the conduit(s) which may have external fins 22 thereon on two opposed relatively wide surfaces of the conduit cross-section. The shell (see, e.g. Figs. 1 and 2) may be rectangular in cross-section and open at both ends which in such case are flanged so that the shell may form part of a longer duct conveying, e.g. air or waste gas over the conduit(s) 16. A plurality of the conduits 16 may be arranged in the shell as two separate banks each conveying a different fluid and the shell side fluid may flow over these banks either in series (see Figs. 1 and 2) or in parallel (see Figs. 5 to 7). As shown in Figs 3 and 4, the shell 12A may itself be contained in a pressure vessel 60 in communication with the inlet 72 for the shell side fluid whereby there is substantially no fluid pressure differential on the shell wall. In other arrangements (see Figs. 5 to 7) where the interior of the shell and pressure vessel are isolated from each other, the pressure vessel may be pressurized or evacuated. The shell may be reinforced (e.g. by bracing means 56, Fig. 2) to withstand any fluid pressure differential on the shell wall. Support means for the tubes within the shell may comprise brackets (43, Fig. 2) or rods (82, Fig. 5) extending axially through the helix of the conduit 16 at the bend portions thereof. Any gas or liquid such as steam or refrigerant may be circulated through the conduit(s) 16. The general flow of the heat exchanging fluids may be cocurrent or countercurrent.

IPC: H01L35/30
Filed: 1960-06-23
Abstract: 927,013. Thermo-electric generators. SIEMENS-SCHUCKERTWERKE A.G. June 23, 1960 [July 3, 1959], No. 22087/60. Class 37. A thermo-electric generator comprises a plurality of thermo-electric elements mounted in a partition which separates two ducts, heatexchanging vanes in the first duct being connected to the " cold " junctions of the elements, and vanes m the second duct being connected to the " hot " junctions, the arrangement being such that an incoming stream of gas passing through the first duct cools the " cold " junctions, and is then heated and passed through the second duct to heat the " hot " junctions. The thermo-electric elements may be of semiconductor material. As shown, Fig. 1, thermoelectric elements 1 extending through, and located symmetrically around, an insulating tube 2, are connected in pairs by vanes 3 to form hot junctions and by vanes 4 to form cold junctions. Air is drawn into the space between tube 2 and a surrounding casing 5 by the action of a fan 8, thus cooling vanes 4; this heated air is used to maintain combustion in an oil burner 7, the hot gas from which flows past and heats vanes 3. The fan 8 is driven by an exhaustgas turbine or by a separate motor. In a modification, Fig. 2, air is drawn in at intake pipe 11 and flows through ducts 13 to the space between tube 2 and a coaxial surrounding cylinder 9 accommodating vanes 4. At the closed end of cylinder 9 the air changes direction towards heater 7, the hot gas from which flows past vanes 3 and out, through an annular space at the intake end of tubes 2 and 9, to a further space defined by tube 9 and a coaxial cylindrical casing 10 at the exhuast end of which is located an exhaust-gas turbine 14 which drives fan 8. When the generator is mounted in a vehicle, fan 8 may be omitted or of lower power. Alternatively, the air intake may be produced by the chimney effect of the exhaust gas. A plurality of oil burners may be used; other fluid fuel may be employed.

Title: A method and apparatus for removing oil and foreign bodies from water
IPC: B01D17/06
Filed: 1962-06-07
Abstract: <PICT:0957640/C3/1> Water is freed electro-phoretically from solid particles, oil dispersions &c., by passing it through a di-electric solvent, preferably of higher specific gravity than water, while applying a high voltage electrostatic field, e.g. of 5-20 V. per cm. Preferably the water passes upwards through the body of the solvent, e.g. CHCl3 or CCl4, as fine droplets.  A suitable apparatus consists of a vessel 11 containing the solvent 14 admitted through a pipe 12, through which the water to be treated flows upwards as droplets from a perforated member 21, connected to an inlet tube 20.  The droplets rise through an opening 26 between an outer earthed electrode 25 coned at the lower end and joined to an upper cylindrical member, and an inner electrode 24 of similar configuration. Each electrode surface is provided with projecting triangular points 25a, 25b and 24a, 24b which are closely spaced and staggered formation.  The inner electrode is connected to a high voltage D.C. supply through electrodes 37, 38, and current leakage to the upper pure water zone 50 is prevented by surrounding the electrode conduit by a tube 60 containing air.  Impurities separate as a supernatant layer on the solvent and are drawn off at an outlet 46.
