Title: Device for mixing a gas current under pressure with an atomized mist of liquid, such as lubricating oil
IPC: F16N7/34
Filed: 1968-01-30
Abstract: 1,206,715. Mixing fluids in flow. DENTATUS A.B. 30 Jan., 1968 [14 Feb., 1967], No. 4841/68. Heading B1C. [Also in Division F2] In apparatus for suspending a mist of oil or other liquid in air or other gas, the main gas current enters the tube 5, passes through openings 12 in a valve member 8 which is lifted from its seat, and through the bores 6 and 7. The openings 12 cause a pressure drop whereby a minor portion of the gas current passes through the annular clearance 26 between a hole 16 in the tube 5 and a suction tube 14, up which liquid is drawn from the transparent container 1 and atomized at the outlet of the tube 14. The oil mist so formed passes under the transparent baffle 18 which intercepts large droplets, and through the passages 19, 37 to rejoin the main gas stream in the bore 6. The amount of liquid entrained may be adjusted by the needle valve 25 in the bypass. The pressure drop and consequently the amount of liquid entrained are maintained substantially constant irrespective of the rate of gas flow, by movement of the valve member 8 to uncover more or less of the openings 12. If gas flow be contained, the valve member 8 may be replaced by a fixed orifice (see Fig. 2, not shown). If it be desired in the embodiment of Fig. 3 shown that the rate of liquid supply increase with increasing gas flow, the compression of the valve spring 9 is increased by means of the adjusting knob 30. Conversely if the rate of liquid supply is to decrease with increasing gas flow, the tubular plug 36 is screwed out into the bore 6 until its plane end 35 acts as a valve seat in cooperation with a plane face 39 on the side of the valve member 8, so that the outlet of the passage 37 into the bore 6 is gradually occluded as the valve member 8 lifts. An embodiment incorporating an air filter (101), air pressure regulator (102) and pressure gauge (116) is described with reference to Figs. 4 and 5, not shown.

Title: Improved manufacture of organic acids
IPC: C12P7/48
Filed: 1930-02-14
Abstract: Organic acids such as citric, oxalic, malic, succinic, gluconic or fumaric acid are prepared by impregnating plant tissue material with carbohydrates, inoculating the material with a selected acid-producing fungus strain and growing the fungus on the material. Selected strains of aspergillus, mucor, penicillium, rhizopus or citromycetes may be used on fructose yielding carbohydrates such as frustose, sucrose, inulin or the like, or a selected strain, e.g. penicillium luteum, may be used on dextrose yielding carbohydrates. Thus, bagasse or dried spent sugar beet cosettes is impregnated with a diluted solution of molasses with or without other nutrient materials and fermented with a selected strain of fungus such as aspergillus niger to produce a desired acid such as citric acid.  The plant material may be disposed in layers in tanks on wood or metal or irregular masses of stoneware may be intermixed throughout the entire mass.  Means for cooling or warming the entire mass may be provided. The cellular structure of the plant material may be broken down by steaming or cooking or by alternate freezing and thawing.  A suitable acidneutralizing agent such as calcium or barium carbonate, zinc oxide or calcium phosphate may be powdered on to the plant material.

Abstract: 778,621. Multiplex transmission. STAATSBEDRIJF DER POSTERIJEN TELEGRAFIE EN TELEFONIE. Feb. 26, 1953 [March 3, 1952], No. 5446/53. Class 40 (4). [Also in Groups XL (b) and XL (c)] A multiplex telegraphy system including a two-way radio link uses a combination of time division and frequency division in each direction so as to increase the time available for each code element. Transmitter.-At any one of the 8 teleprinter units, e.g. unit A, Fig. 1, the 5-element code output of a tape transmitter "Tape A Transit," is converted into a 7- element code at "CONV 5/7 CC<SP>1</SP>" and connected by a line ChA to the control centre which controls the multiplex radio transmitter and corresponding receiver. At the control centre, distributers FP<SP>1</SP> and TC sample the 8 incoming signals and convert them to a time division multiplex signal in which the order of transmission is the first code element of the signals from units A, E, C, G, then in turn, elements 2 to 7 in the same sequence, followed in similar manner by the signals from unit B, F, D and H, Fig. 3 (not shown). The multiplex signal is converted to a voice frequency on/off signal at TTK and sent by line Tr to the transmitter, Fig. 4, where it is converted back to a D.C. signal and amplified, before odd and even elements are selected by gates GI, GII respectively and passed to two frequency shift keyers FSKI, FSKII to control the reactance valves ReI and ReII thereby producing in both keyers, frequencies p and q. These outputs are mixed at MiI with a sub-carrier r, and at MiII with a different sub-carrier s. The summation frequencies are selected by high-pass filters FI, FII. The four sub-channel frequency signals are sampled in sequence by a distributer Comm II to provide a combined time division and frequency division multiplex signal for transmission from RTr. Receiver.-At the receiver, Fig. 6, the two sub-carriers rand s are selectively received at RRI and RRII respectively, and the frequency shift signals are converted to D.C. signals at FSA I and FSA II before being combined alternately by a distributer Comm III to form a time division multiplex signal that is tone keyed at TK and sent by line Re back to the control centre, Fig. 1. At the control centre the elements of the multiplex signal are distributed at RC and FP to their 8 teleprinter channels, e.g. "Printer A."
