Title: Improvements relating to the production of propionic acid by fermentation
IPC: C12P7/52
Filed: 1932-11-08
Abstract: Propionic acid is produced by fermentation of mashes containing soluble carbohydrate with at least 25 per cent of fructose or carbohydrate material equivalent to such quantity of fructose, by means of mannitol-forming and propionic acid-forming bacteria. The two kinds of bacteria may be added together or in any order. The propionic bacteria may be various strains of B. acidi propionici and the mannitol-forming bacteria may be B. mannitopaeum, B. gayoni Lactobacillus fermentum or those described in the article in Journal of Biological Chemistry, 64, 643.  Other bacteria may also be added such as those which produce lactic acid from carbohydrates (e.g. Streptococcus lactis and Lactobacillus casei 2); those which hydrolyse nitrogenous substances (e.g. Proteus vulgaris 3); and those which ferment salts of organic acids (e.g. B. alkaligenes).  Suitable fructose yielding carbohydrates are sucrose, raffinose, gentianose and their inversion products, molasses, inverted molasses, hydrolysed inulin, and hydrolysed tubers of Jerusalem artichoke; and carbohydrates fermentable by the propionic acid bacteria may be glucose, maltose, lactose, "hydrol" (the molasses obtained in the corn sugar industry) and hydrolysed grain.  The mash should contain at least 25 per cent of fructose or its equivalent.  The term "fructose equivalent" is defined as the quantity of the carbohydrate which yields the same amount of mannitol as does 1 per cent of fructose; thus 8 parts of sucrose are equivalent to 1 part of fructose.  Nutrient material may be added, such as steep-water (i.e. the effluent from the treatment of maize for the production of corn starch), butyl acetonic slop or distillery wastes from other fermentation processes.  The acidity may be pH5,4--6, maintained by excess of calcium carbonate, and the temperature may be 30-31 DEG  C. Examples are given.

Title: Improvements relating to the production of non-woven fabrics
Inventor: HARTMANN LUDWIG
IPC: D04H3/03
Filed: 1963-08-09
Abstract: Garments are made by extruding a molten fibre-forming polymeric material e.g. polyamides, P.V.C. through apertures arranged in one or more rows to form one or more sheets of continuous filaments, stretching the filaments by gas streams forced out of slots one on each side of each row of apertures and adjacent and parallel to that row, and leading the or each sheet of filaments, together with its associated gas streams, through an open-ended duct through which the filaments and gas pass substantially without turbulence, the filaments being stretched and set whilst being kept parallel to and separate from one another, and forming a fleece by collecting the sheet or sheets of filaments on a carrier.  A sheet may be made from such a fleece but preferably garments are made directly by forming the fleece on a carrier having the shape of the garment.  Such a carrier may be rotated or vibrated.  In an example, filaments are collected on a rotating screen carrier in the form of a pair of trunks or briefs and having an internal suction system.  The carrier was so rotated as to form a uniform fleece of 100 grammes per square metre, which was sprayed with a bonding agent in the form of an acrylic resin dispersion and then dried into a solid, whereupon it was withdrawn from the carrier as a garment.

Title: Improvements relating to accelerometers
IPC: G01P15/09
Filed: 1960-09-13
Abstract: 959,454. Piezo-electric transducers. ENDEVCO CORPORATION. Sept. 13, 1960 [Sept. 15, 1959; Feb. 12, 1960], No. 31583/60. Heading H4J. [Also in Division G1] An accelerometer for mounting in a cavity includes a body having a base whose periphery can be attached to the walls of the cavity, and a pillar projecting from the base into the cavity, a transducer element being mounted on the pillar to produce an electrical signal in response to acceleration. The accelerometer is in the form of a plug-in unit which can be inserted in a cavity in a suitable mounting block which is secured to the body to be tested by an insulated bolt. Base 20 of the unit is threaded at its periphery to screw into a cavity in block 12, and pillar 24 bears on a bearing plate 42 counter-sunk into the bottom of the cavity. The base and pillar have a central bore 22 to receive electrical conductors for connection to coaxial cable K. The piezoelectric element is annular and is cemented to an annular carrier sleeve 36 brazed in a cavity in base 20. Annular inertia mass 34 is cemented to crystal 30. Carrier sleeve 36 is spaced from pillar 24 to leave a stress relief gap 40 to prevent strains on the pillar being transmitted to the crystal. In a modification, Fig. 3 (not shown), the unit is placed in a central cavity in a mounting block and a stud is screwed into the bottom of the block for securing it to the body under test. Bearing plate 42 may be replaced by a projection integral with the bottom of the cavity. In another embodiment the mounting block is water cooled, Fig. 4, the water passing down in a helical channel 94 to a chamber 92, which contains balls 88 retained by a ring 90, and up a second helical channel 96. A three conductor coaxial cable is then used, the conductors being connected respectively to inertia mass 134, to a metal ring plate on a ceramic carrier sleeve 136, and to the body 20 of the unit. This also eliminates the need to insulate the mounting block from the body under test. In a further embodiment Fig. 5 (not shown), the carrier sleeve is secured to the end of the central pillar remote from the base, the pillar projecting beyond the sleeve to bear directly on the bottom of the cavity. A stress-relief gap is again provided. Specification 959,452 is referred to.

Title: Improvements in or relating to methods and devices for the production of tubular bodies
IPC: B29C53/60
Filed: 1959-09-16
Abstract: 861,556. Making non-metallic tubes. POLYSTAR A.G. Sept. 16, 1959 [Sept. 25, 1958], No. 31613/59. Class 99(2). Tubular bodies are continuously produced from synthetic resins associated with a reinforcing and filling material by forming an initial support winding on a rotating conical surface, winding at least one strip of material comprising synthetic resin helically on to the support winding, the tubular body thus formed being continuously moved axially along the conical surface and subsequently hardened. As shown, a strip 6 of paper is helically wound on to an electrically or steam heated conical core 1 which is rotated by an electric motor 2, the overlapping edges of the strip being bonded together by an adhesive, such as epoxy or ethoxylene resins or polyurethanes, supplied through a bonding device 7, and the outer surface of the strip being sprayed with an adhesion-inhibiting medium such as silicone rubber by means of a nozzle 8. Alternatively, the core is wound with thin metal foil, thermoplastic foils of polyvinyl chloride, acetyl cellulose, polyester, epoxy, ethoxylene, phenol or silicone resins or with foam substances or mixtures thereof formed from polyvinyl chloride, polystyrene or polyurethane. Balsa wood or expanded cork may be combined with the plastic material. The overlapping edges of the strip 6 may be provided with interengaging corrugations or, in the case of thermoplastic strips, may be welded by means of hot air. A strip 9 of glass fibre or fabric which is soaked in a polyester resin, an ethoxylene resin or a polyurethane contained in a bath 12 is then helically wound on the surface 6a formed by the strip 6. More than one strip may be wound together or in succession. The outer surface of the strip is then sprayed with synthetic resin containing hardening agents and the tube is cured in a polymerisation chamber 22. Loose fibres may be applied to the tubular surface prior to hardening by means of nozzles 18, 19, 20 and the surface of the tube is smoothed by rollers 21 mounted around the tube. The finished tube is removed by means of rollers 23 and cut to the desired length by an automatically operated cutter 24. The winding and polymerisation steps may be repeated to form layers of different plastic material. The surface of the finished tube may be subjected to an after treatment by lacquering, coating, flaking, roughening or stamping. The initial support winding may also be formed by injecting plastic material in a heated revolving internally, conically-shaped sleeve from which it is released after polymerisation.
