Abstract: 1, 042, 674. Folding sheets. AURIOL (Guildford) Ltd. April 1, 1965 [Jan. 6 1964], No. 616/64. Heading D1S. [Also in Division E2] A device to facilitate the manual folding of sheets comprises a rectangular frame A with a sliding rail B parallel to the longer sides a thereof and formed with an eyelet b at each end to surround the shorter sides a<SP>1</SP>. A rectangular boss a<SP>2</SP> is formed on one side a and carries a spindle a<SP>3</SP> extending into a sleeve d<SP>1</SP> in a bracket D which is affixed to a vertical wall or panel. A compression spring d<SP>2</SP> extends between a plate d<SP>4</SP> on the spindle a<SP>3</SP> and the bracket D. In use, one end of the sheet to be folded is doubled on itself and passed under the outer side a and over the rail B which is drawn outwards. The free end of the sheet is stretched and the sheet is folded longitudinally. Further longitudinal tension disengages the boss a<SP>2</SP> from the recess of the bracket D and the frame A is rotated through 90 degrees. The sheet is folded transversely by walking toward the bracket D. The trapped end of the sheet is released and the frame A is returned to its original position. The spring d<SP>2</SP> reinserts the boss a<SP>2</SP> in the recess. When not in use, the frame A may be employed as a towel rail or trouser hanger.

Abstract: 1,053,848. Aseptic propagation of microbial cultures. COMMONWEALTH SCIENTIFIC & INDUSTRIAL RESEARCH ORGANIZATION. Nov.11 1963 [Nov.12, 1962], No. 44344/63. Heading C6F.  Microbial cultures are aseptically propagated by aseptically transferring sterilized medium to a sterilized container, inoculating the medium in the container under aseptic conditions, incubating the inoculated culture under aseptic conditions, transferring a portion of the incubated culture to another vessel under aseptic conditions as by passing a sterile vapour into the container under pressure, thereby retaining a portion of the incubated culture in the container to serve as an inoculum for a fresh culture, supplying fresh sterilized medium under aseptic conditions to the container, and incubating under aseptic conditions the fresh culture formed. Bacterial, yeast and mould cultures used in the manufacture of cheese, yoghurt, cultured cream and cultured buttermilk, and in wine-and beer-making are instanced. Mention is made of employing bacteriophage -unrelated cultures, or pairs of such cultures, in cheese-making on successive days. The apparatus consists essentially of a jacketed container M for the propagation of mother cultures, a bulk culture (bulk starter) vessel V, and an autoclave A. The culture medium in the container M is inoculated through a membrane normally covered by a cap 12 and air, oxygen, carbon dioxide or other gas for the incubation is admitted through a sterilizing filter 17. The system includes a relief valve 18. The container M together with its associated valves 3, 4 and water cooled manifold 16, can be detached from the system at joints 8, 9, 10, 14 and 15, whereby a culture in the container may be incubated and then preserved by deep-freezing until required for use in the vessel V. Similarly, the air filter 17 and its associated valve 6 are detachable at the joint 11 for separate sterilization. Steam for sterilizing the system is generated in the autoclave A, wherein also the supplies of culture medium are first sterilized, before admission to the container M. Steam admitted to the container M through valve 3 forces a portion of the culture up through pipe 13 and valves 4, 5 into the vessel V. The operation of the apparatus is described in detail.

[Also in Division H1] A semi-conductor diode arrangement comprises a number of laser diodes or luminescence diodes on an insulating carrier body 1 with each PN junction 5 perpendicular to the carrier body. Fibre light waveguides carry light to or from the diodes. The diodes 2 are of Group III/V material, such as gallium arsenide or gallium phosphide, doped with zinc and tellurium, and the carrier 1 is of high resistivity gallium arsenide or sapphire. Opposite surfaces of each laser diode are provided with reflecting layers 6, 7 to form a Fabry-Perot resonator. These layers may be formed of alternate calcium fluoride and glass layers, each component layer having a thickness of one quarter of the laser beam wavelength, and they may be applied both directly to the diode body or so that one is on the diode body farthest from the carrier and the other on the other side of the carrier from the diode so that the carrier forms part of the resonator. If the PN junction of a diode is arranged to lie in the correct crystal lattice plane the diode surfaces themselves will act as resonator layers. Input to the diode is via contacts 9, 10 or, for higher frequencies, in the form of a line.

In cultivating micro-organisms, oxygen is fed into the culture medium under super-atmospheric pressure e.g. 1 atm. gauge pressure, and the culture medium is continuously stirred, preferably with an intensity characterized by a Reynolds number of not less than 1 x 10<SP>5</SP>. Employing two consecutively connected fermenters, the unused oxygen in the first fermenter is removed from culture fluid and passed to the second fermenter, along with the carbon dioxide formed in the cultivation, to saturate the culture fluid flowing continuously from the first fermenter. Unused oxygen from the second fermenter is freed of carbon dioxide and returned to the first fermenter. The culture medium may be treated with ozone at a rate of 5 to 10 mg. per litre during or prior to the cultivation. An example is directed to the cultivation of a Candida yeast on C 10 -C 24  n-paraffins or glucose.

Multiphase alloys are produced by vacuum evaporation of the constituents from controllably heated sources and deposition as a coating thicker than 0À01" on a temperature controlled collector, the source and collector repeatedly passing each other so as to deposit successive layers. The alloy constituents may be evaporated from a single or several sources and the collector is preferably reciprocated or rotated above the source at 50-1500 r.p.m. The deposited alloy may be heat treated before or after removal from the collector and may be mechanically worked. Deposit thickness is controlled by varying the speed of moving collector, and the evaporation rate. Oxides, carbides and intermetallics may be deposited with the metal to form dispersion hardened alloys. Separate moveable shutters are located between sources and collector. The pressure, heat input, temperature, evaporation and deposition rates are monitored. The evaporant sources are continuously replenished by a wire feed and the heating may be effected by electron beam. The following alloys are deposited from separate sources: Al-7%Ni; Al-4À3%Ni; Al-5%Fe; Al-6À5%Ti; Al-5À5%Cr; Al-5%Mn; Al-Si; Al-Mg; Al-Co; Al-Sb; Al-Cu; Mg-Fe.
