Patent GB-831125-A (GB)
Title: Process for fermentative production of antibiotics
Filed: 1956-05-08
Abstract: A process for the fermentative manufacture of antibiotics comprises carrying out the fermentation without maintenance of aseptic conditions in an aqueous medium which has been pasteurized at 70-100 DEG  C. for 10-120 minutes and which contains an antibiotic capable of inhibiting the growth of microbial contaminants while allowing growth of the producing microorganisms, said antibiotic being present in a concentration of not less than 10 gamma/ml. and preferably in a concentration of 50 gamma/ml.  Broad spectrum antibiotics such as the tetracyclines, erythromycin, carbomycin, "Albamycin" (Registered Trade Mark) and chloramphenical are preferred but others such as streptomycin may be used for the inhibition of microbial contaminants.  The "protective" antibiotic may be added to the culture medium in the form of (a) the antibiotic per se (b) an inoculum of the "producing" micro-organism containing sufficient of the "protective" antibiotic, or (c) the fermented nutrient medium from the preceding fermentation.  In the case of (b) the "producing" micro-organism may be one which coproduces the "protective" antibiotic, e.g. Streptomyces rimosus which produces rimocidin (protective antibiotic) besides oxytetracycline, and Streptomyces griseus which produces actidione besides streptomycin.  The inoculum is prepared under sterile conditions but the main fermentor is not hermetically closed and the air for aeration need not be sterile but is deprived merely of mechanical impurities.

Abstract: 637,073. Locks. WILLIAMS, E. D. May 27, 1948, No. 14370. [Class 44'] In a door latch of the kind in which the outside handle is rendered inoperative by operation of a key lock, the handle 3 has a stem 14 surrounded at the inside end by a sleeve 12, connected to the latch mechanism, to which it is coupled or uncoupled by a lever 142 mounted in a slot in the stem and controlled by a barrel lock 17 in the handle boss. The lever has a curved portion about which it rocks and a locating peg 143. A spring 147 urging the tooth 146 of the lever into engagement with a socket in the sleeve 12 also acts on a ball 148 which, engaging in an opening. 122, locates the handle'in the coupling position relative to the sleeve. The lever is controlled by a cam 172 carried on the inside member of the barrel lock 17. The barrel lock has two sets of pin tumblers at right angles so that the key may be withdrawn in the locked or unlocked position. A projection 177 inside the outer cylinder of the lock limits the rotation of the inner barrel and also co-operates with a notch in the back of the key as a further safety provision.

Means for grinding gear teeth on wheels or cutters comprises means for transversely reciprocating a spindle 15 carrying the workpiece 11, as it is rotated, into and out of engagement with a stationary grinding wheel 10, the workpiece being indexed at one end of its path. When the one sides of the teeth have been finished, the gear is reversed. The spindle 15 is supported on a slide 13 reciprocated by a piston 19 on an angularly-adjustable bracket 16. A sector 47 and tapes 48, 49 oscillate the gear together with an indexing assembly 35 having a sliding and swinging lever 30 and a sliding pawl 38. When the slide 13 is moved to advance a tooth against the wheel, a sliding rack 23 is carried along until it meets a stop 24. A gear 21 meshing with the rack and mounted freely on the spindle 15 is carried on by the slide. The gear carries cams 31, 32 which ride under the swinging lever 30. When the slide 13 is returned, the rack 23 is held by the stop 25 and the lever 30 swings over the cam 32, engages a lever 34 and forces it against the spindle 15 causing the spindle and the gear 21 to rotate together. The pawl 38 is successively released and re-set and the slide continues its movement until it engages a reversing stop 29.

Title: Improvements in the production of globular particles containing alumina
Inventor: CONRAD RICHARD
IPC: C01F7/02
Filed: 1959-05-01
Abstract: Globular particles containing alumina, which may be used as catalysts, are obtained by mixing an aluminium oxide hydrosol with a finely ground solid additive in an amount of 30 to 90% by weight with reference to total dry substance and with hexamethylene tetramine or urea, dripping the mixture into a liquid immiscible with water at elevated temperature, separating the resultant particles after gelation and drying and calcining them.  In examples the solid additives mixed with the aluminium oxide hydrosols are aluminium hydroxide, silica gel, titanium dioxide, kaolin and ground quartz, the base is urotropine (hexamethylene tetramine), and the mixture is dripped into heated paraffin oil; in one example aluminium hydroxide and cobaltous hydroxide are added to the hydrosol, and after calcination the globules are soaked in a solution of molybdic acid and calcined.  A list of other solid additives is given.  The aluminium hydroxide hydrosols are prepared by dissolving aluminium chips in aluminium chloride solution and in aluminium nitrate solution.

Title: Process for the manufacture of artificial fibres from polymeric caprolactam
IPC: D01F6/60
Filed: 1950-06-15
Abstract: In the manufacture of artificial fibres from polymeric e -caprolactam by melt-spinning, the unstretched fibres are first washed with an aqueous medium advantageously above 50 DEG  C., preferably at 80-100 DEG  C., then lubricated in a separate operation by an emulsion of the oil-in-water type, and then conditioned in an atmosphere of relative humidity 55-70 per cent, preferably 60 per cent, at 17-25 DEG  C., preferably 19-20 DEG  C.  The fibres may be dyed, e.g. with acid dyestuffs or cellulose acetate dyestuffs, at the same time as they are washed.  The wash liquid may be water, aqueous solutions of salts such as sodium chloride or dilute aqueous solutions of alkalies.  The emulsified lubricant may be oleic acid, an oil or a fat and the emulsion may contain a soap, e.g. ammonium oleate or a mixture thereof with triethanolamine oleate.  In an example, polymerized e -caprolactam containing 12 per cent of water-soluble material is meltspun to form a loose cake of twisted yarn, which is washed with water at 96 DEG  C. for one hour.  It is then centrifuged, lubricated by immersion in a 6 per cent aqueous solution of ammonium oleate in which 7 per cent of oleic acid has been emulsified and suspended for 36 hours in an atmosphere of relative humidity 60 per cent at 20 DEG  C.  The yarn is then stretched in the ratio of 1 : 4 (initial to final length) and further twisted.  The emulsion may alternatively consist of 13 per cent of mineral spindle oil emulsified in a 6 per cent solution of ammonium oleate.  U.S.A. Specifications 2,253,176 and 2,300,083 are referred to.
