Title: Improvements in or relating to the generation of gases from carbonaceous material
Inventor: MOORE FREDERIC HOLLWAY
IPC: C10J3/46
Filed: 1953-09-21
Abstract: 734,914. Gasifying powdered carbonaceous materials. TEXACO DEVELOPMENT CORPORATION. Sept. 21, 1953; No. 25963/53. Class 55 (1). Particulate carbonaceous fuel suspended in steam is introduced tangentiallyinto an elongated cylinder and near the inlet a tangential stream of oxygen-containing gas is separately admitted so as to flow directly into the fuel stream, the reactants being given a spiral motion along the wall and the gases produced withdrawn axially. Crushed coal, coke, lignite, &c., mixed with superheated steam is introduced through a port 8 and oxygen directed into it through an adjacent port 9 both streams flowing tangentially into the upper end of an elongated cylindrical reaction zone 7 and the oxygen being prevented by the coal and steam from impinging directly on the wall. The swirling motion set up causes molten ash to be thrown out of the stream for discharge through a slag tap 10 and product gases are withdrawn through a duct 16 from a point slightly above the centre of the zone. A pilot burner 21 is disposed above the point at which the coal and oxygen meet. The oxygen is preferably preheated to 400-600‹ F. and the steam to 500‹ F. or higher, e.g. up to 4000‹ F. A hydrocarbon or other gas may be used alone or with steam to introduce the fuel. Temperatures of 2000-3000‹ F. and pressures above 100 1bs. per sq. in. are suitable.

Title: Gyroscopic flowmeter
IPC: G01F1/84
Filed: 1954-09-08
Abstract: 770,780. Rotary meters. DETROIT CONTROLS CORPORATION. Sept. 8,1954 [Sept. 16, 1953], No. 25976/54. Class 110 (2). [Also in Group XXIX] A rotary flowmeter comprises a coil 10 with inlet and output passages 12, 14 connected to conduits 16, 18 respectively which are rotatably supported in blocks 20, 22, the passages 12, 14 being aligned along an axis perpendicular to the axis of symmetry of the coil and the conduits 16, 18 being aligned along an axis perpendicular both to the axis of the passages and the axis of the coil. Fluid-tight slip couplings 24, 26 are provided at the ends of the conduits 16, 18 respectively for connection to stationary fluid supply and discharge conduits. The conduits 16, 18 and hence the coil 10 are rotated about the axis of the conduits by means of a motor through a belt drive 32 and pulleys 28, 30. Conduits 16, 18, passages 12, 14 and coil may be formed as a single element, and the passages 12, 14 are relatively elastic so that they can twist about their axes. As a result of the fluid flow and the rotation of the coil, a couple is set up tending to twist the passages 12, 14 about their common axis. This couple is measured by means of strain gauges 40, 42 connected through leads 46, 44 to a recording meter (not shown), the meter being calibrated to give the mass now rate through the coil. In a modification, the coil is given a reciprocating motion instead of a rotary motion.

Title: Production of l (+)-glutamic acid
IPC: C12P13/14
Filed: 1960-07-26
Abstract: L(+)-glutamic acid is prepared by aqueous aerobic fermentation of a nutrient medium containing sources of carbon and nitrogen, with a biotin-requiring, glutamic acid producing microorganism, the medium containing biotin in excess of the amount required for optimum production of the glutamic acid, an inhibitor being added to the fermenting medium subsequent to inoculation of the medium with the micro-organism, the inhibitor and the amount of it being such as to decrease, as fermentation proceeds, the intracellular L(+)-glutamic acid to a level less than half of that of a fermentation carried out without inhibitor and to increase the ratio of extracellular to intracellular L(+) glutamic acid to a value greater than 50, the amount of biotin, however, not being greater than 1 gram per litre of liquid medium. The inhibitor may be an antibiotic e.g., a penicillin, including Penicillin G, a -phenoxyethyl penicillin and a -phenoxymethyl penicillin which penicillins may be used in the form of a procaine, dibenzyl ethylenediamine, calcium, sodium, potassium or other salt thereof, cephalosporin C, oxamycin, novobiocin, tetracycline, oxytetracycline, chlortetracycline, streptomycin, dihydrostreptomycin sulphate, bacitracin, chloramphenicol and neomycin sulphate; phenol, resorcinol, sodium propionate and cetyl trimethyl ammonium bromide. The inhibitor is preferably added when the micro-organism has grown to the extent that would occur in the presence of about 1 to 5.0 parts of biotin per thousand million of medium. The amount of penicillin inhibitor is suitably 0.05-10 units per mol. of broth. The micro-organism may be a suitable strain of Bacillus subtilis, Escherichia coli, Micrococcus glutamicus, Bacillus-megaterium-Bacillus cereus intermediate type, Brevibacterium divaricatum, Brevibacterium aminagenes, Arthrobacter globiforme, Bacillus megaterium, Brevibacterium alanicum and Brevibacterium lactofermentus.  The nutrient medium may comprise for example 20-37.5 parts of biotin per thousand million parts of broth.  The carbon source may be dextrose, dextrin, beet molasses, cane molasses, corn syrup, black-strap molasses or hi-test molasses, some of which also provide the excess of biotin.  The nitrogen source may be urea, ammonia, an ammonium salt or corn-steep liquor.  The nutrient medium usually also comprises phosphates, sulphates, and magnesium, manganese, potassium and, may be, iron salts. The fermentation is preferably effected at a pH of 6.0 to 8.5, suitably accomplished by addition of urea, ammonia or an alkali metal hydroxide. Examples are given wherein Micrococcus glutamicus is used as micro-organism with excess of biotin and various of the above mentioned inhibitors or, comparatively in the absence of an inhibitor, or with inhibitor and biotin not in excess. Specifications 788,335, 826,097, 839,597, 844,910 and 849,280 are referred to.
