Abstract: 826,937. Pneumatic conveyers. BABCOCK & WILCOX Ltd. April 4, 1956 [April 6, 1955], No. 10031/55. Class 78 (1). Means for transferring powdered material from one region to another at a different pressure comprises a hollow rotor 104 having a material outlet 112 remote from its axis and arranged so that a seal to resist the difference in pressure is formed by material within the rotor compacted by centrifugal force, means for supplying material to the rotor at an adjustable rate through a shoot 161, pipes 150 for directing compressed air into the outlet to disturb the compacted material and cause its discharge, and means for controlling, in accordance with the weight of material in the rotor, the supply of material to and the discharge from the rotor in order to maintain within the rotor a quantity of material sufficient to provide the seal. The rotor is disposed within a cylindrical casing 101 through which air at high pressure passes from a supply pipe 102 to an outlet pipe 103. The bottom 107 of the rotor is secured to a driving-shaft 163 which is slidably mounted in fixed bearings 164, 165. The weight of the rotor and its contents is transmitted by a rotary thrust bearing 183 to the non-rotating spindle 168 of a compressed air valve 169. This valve has a centre chamber 170 connected to an air supply pipe 171, upper and lower chambers 172, 173 connected by an equalizing pipe 174, needle type valve members 175, 176 on the spindle for controlling the flow from the central chamber to the others, and diaphragm walls 181, 182 of the chambers 172, 173 connected to the spindle. Three pipes 149 lead from the chamber 172 into the casing 101 and terminate adjacent the outlet 112. Escape of air from the casing is prevented by water seals 185, 188.

Abstract: 1,208,443. Cultivating micro-organisms on gaseous hydrocarbons. BRITISH PETROLEUM CO. Ltd. Feb.12, 1968 [March 3, 1967], No.10086/67. Heading C6F. A micro-organism is cultivated in a cultivation zone in the presence of an aqueous nutrient medium, a normally gaseous hydrocarbon and oxygen, the micro-organism being of a strain which consumes the hydrocarbon, broth is continuously removed to a quiescent zone, and part of the broth is recycled from the quiescent zone to the cultivation zone. The ratio of the volume of broth in the quiescent zone to the volume of broth in the cultivation zone is less than 1:2. The term "microorganism" covers yeasts, moulds and bacteria. Micro-organisms: Methanomonas methanica (Pseudomonas methanica or Bacillus methanicus), Methanomonas methano-oxydans, Pseudomonas oxalaticus and Methylococcus encapsulatus. Hydrocarbons: Methane, ethane, propane and butane. An example is directed to the cultivation of an unidentified, mixed population of bacteria, containing methane-consuming bacteria, which was isolated from pond mud. The substrate employed was methane at 4 vol. /vol. /hour in admixture with air which was supplied at 16 vol. / vol. /hour. The cultivation was conducted in a tower fermenter 10 cms. in diameter and 70 cms. high, and sufficient of a specified enrichment mineral medium, containing 10 mg. glycine per litre, was continuously fed to the fermenter to maintain a dilution rate of 0À05. An offtake point at the top of the fermenter was connected to the top of a vertical cylindrical vessel 10 cms. in diameter and 30 cms. high which served as the "quiescent zone". Offtake points at the lower end of the quiescent zone served for the continuous recycling of aqueous nutrient medium at a rate of 60 litres per hour by continuous pumping and for the withdrawal of product. The withdrawn product can be heated or acidified to denature the protein and then centrifuged or filtered. The cellular densities of the broth at the offtake points from the fermenter and quiescent zone were 1À5 and 2À0 grams/litre, respectively.

[Also in Division H2] A force or pressure transducer comprises a crystal to which the force or pressure is applied through elements having spherical surfaces, the crystal having electrodes bonded to its faces and forming the frequency control crystal of an electronic oscillator. Crystal 26 has sputtered or plated electrodes 28, 30 on which bear synthetic sapphire balls 40, 48. Ball 48 is held in a recess in a seismic mass 50 supported by a diapragm 52. Electrodes 28, 30 are connected in an oscillator circuit whose output forms one input of a mixer, the other input of which is provided by a standard frequency oscillator, so that the mixer gives a digital signal indicative of acceleration. The signal may be integrated to give an analogue acceleration signal, further integrated to give a velocity signal, and still further integrated to give a distance signal. The seismic mass is air damped by extending it into a recess in the end of shank 56, as shown. Changes in temperature and air density are compensated by varying the air pressure through inlet 68. The apparatus may be used to measure the fluid pressure applied at 68. Mass 50 is made as small as possible if the pressure measuring embodiment is likely to be subject to acceleration. The sensitivity and linearity may be adjusted by using larger or smaller balls 40, 48, and by varying their positions on the crystal surface. Measurement of altitude, speed and Mach number of an aircraft is referred to.

Sludge from vessel 7 is sprayed into furnace 11 of the second stage and thermally decomposed. Gas from furnace 11 heats tower 14. Acid from tower 14 is separated from precipitate in decanting vessel 17, passes to evaporating tower 24 of the third stage and is concentrated to 63% by weight H 2 SO 4 . Sulphate sludge from vessel 17 is sprayed into furnace 21 from line 20 and gas from this furnace heats tower 24.

[Also in Division F2] Textile belting or webbing is jointed by cutting a series of V-shaped notches across the full width of each of the two ends of the belting or webbing to be joined, lining the sides of the notches with solid fusible polyurethane, positioning the notched ends together in interengaging relation to cause the sides of the notches to butt up against the solid polyurethane, and fusing the joint between flat surfaces by the application of heat and pressure. The belt may be woven from yarns made of cotton, hair, flax, rayon, nylon or polyester fibres or combinations thereof and may be coated or impregnated with a dressing material. Preferably, the V-shaped notches are cut in such a manner that the ratio of notch length to width lies in the range 2 :1 to 30 : 1, e.g. 9 :1. The peaks of the notches may be rounded or squared. Before assembly with the polyurethane strips, the sides of the notches may be coated with a liquid adhesive primer, e.g. a solution of polyurethane in tetrahydrofuran. The polyurethane strips are of a thickness equal to that of the belt and of a width between <SP>1</SP>/ 64  inch and # inch. A thin sheet of the fusible solid polyurethane may be placed over the top and bottom surfaces of the belt prior to the fusing of the joint. Additional reinforcement of the joint may be provided by placing an open mesh fabric or scrim cloth, e.g. of nylon or polyester yarn, over the top and bottom surfaces of the joint either prior to the fusing of the joint or at a later stage. The joint may be assembled on a metal plate, covered with another plate and then placed in a press. Alternatively, the joint may be assembled directly on the bottom platen of the press. The platens of the press or the metal plates may be coated with a silicon release agent.

Concretes of low specific gravity are formed by fixing moulded elements of a shapable material such as vitreous clay, or non-vitreous clay, subsequently receiving a vitreous coating and sanding. The aggregate is prepared by moulding clay in uniform moulds, e.g. of spherical form, burning, glazing to render non-absorbent, and causing sand to adhere to the glaze before cool to produce a rough surface. Such aggregates, in differing forms and sizes, from a quarter to three-quarters of an inch in diameter, are employed with sand and lime to constitute concretes, which, if they are to be moulded, may have the aggregate elements systematically arranged according to size in the mould. The matrix material, such as cement, is caused to flow in from below upwards preferably under pressure so as to displace air and obviate bubbles.
