Title: Improvements relating to producer gas plants and in controlling the composition of producer gas
IPC: C10J3/72
Filed: 1936-10-22
Abstract: 485,655. Gas producer plant. MACDONALD, J. A. Oct. 22, 1936, No. 28756. [Class 55 (i)] In a gas-producer, suitable for use with an internal-combustion engine, the ratio of the water to the air supplied to the producer is increased with the power demands on the engine whether or not engine suction on the producer increases. While the engine is running under light load, the comparatively high proportion of air to steam supplied to the producer establishes in the fuel bed a reserve of heat which is used to maintain the endothermic reaction taking place when an increased proportion of steam is supplied. A gas producer 1, preferably of the kind described in Specification 336,932, [Class 55 (i)], supplies gas to an engine 40 through a pipe 41 leading to a mixing chamber 44 to which air is admitted through an inlet 45 controlled by a valve 46, and from which chamber the mixture passes through a throttle valve 47 to the engine. The air inlet and throttle valve are controlled by an accelerator pedal 48, which, by links and levers 62, 60, 59, 56, also controls a drip feed 22 by which water from a tank 37 is supplied by a pipe 21 to a tuyere 5. A self closing flap valve 12 admits air to the producer under suction from the engine. A water jacket 7 for the nozzle 5 is provided with flow and return pipes 8, 9. The water from pipe 21 flows through passage 18 to an outlet 19 into the air supply. An arrangement by which water is supplied at an increased rate under heavy load comprises a link 81 attached to the accelerator lever 80, and operating through a dash-pot 82 a piston 84 in a cylinder 85 supplied with water through a pipe 86. Pressure on the pedal 48 injects through pipe 87 an additional supply of water to the fuel bed of the producer.

Patent GB-903344-A (GB)
Title: Polyethylene processing method
IPC: C08J7/044
Filed: 1960-08-22
Abstract: The surface characteristics of articles consisting of high-density molecularly oriented polyethylene having a crystallinity ratio of at least 60% are modified by subjecting the article to controlled surface oxidation, the reduction in the crystallinity ratio brought about thereby being not more than 20% of the initial value, reacting the surface-oxidized article with a saturated organic diisocyanate and reacting the resulting product with a polymer containing free hydroxyl and/or carboxyl groups, whereby the polymer becomes bonded to the surface of the polyethylene article through linkages derived from the diisocyanate.  As modifications of this process: (i) the polymer containing hydroxyl and/or carboxyl groups may be separately reacted with an excess of the diisocyanate and the product so-formed is then reacted with the surface-oxidized polyethylene, and (ii) the surface-oxidized polyethylene may be reacted with the polymer containing hydroxyl and/or carboxyl groups in the presence of the surface-oxidized polyethylene.  The surface oxidation of the polyethylene may be effected by means of potassium permanganate, sulphochromic acid, aqua regia, Caro's acid, ozone or high energy irradiation in the presence of oxygen or air.  Organic diisocyanates specified are tolylene and diphenylmethane diisocyanates.  Polymers specified for reaction with the diisocyanate-modified polyethylene are polyethylene glycol, polypropylene glycol and a polyester derived from diethylene glycol, maleic acid and phthalic anhydride, this last polymer being used in conjunction with styrene as a cross-linking agent and a mixture of benzoyl peroxide and dimethylaniline.  The polyethylene used may be in the form of a film, fibre or fabric.

Title: Tetracycline and chlortetracycline complexes
IPC: C07C233/00
Filed: 1961-02-27
Abstract: The invention relates to the production of N.N1-dibenzylethylene-diamine complexes of tetracycline and of chlortetracycline by fermentation of an aqueous culture medium containing assimilable carbohydrates and organic nitrogen as well as mineral salts with any tetracycline or chlortetracycline-producing strain of a species of the genus Streptomyces, especially S. lusitanus CBS 101-A, characterised by the fact that the fermentation is carried out in the presence of a water soluble salt of N.N1-dibenzylethylenediamine, e.g. p  the acetate or lactate under submerged aerobic conditions at a temperature of 24 DEG -30 DEG C., whereafter the resulting complexes are recovered as such or as acid addition salts thereof from the culture medium.  The complexes may be isolated by adjusting the pH of the acidified and filtered broth to 7-9,5 with ammonia or an alkali or alkaline earth metal hydroxide. In the case of the alkali or alkaline earth metal hydroxides the corresponding dibenzylethylenediamine metal complexes of tetracycline or chlortetracycline are formed.  The dibenzylethylenediamine complexes of chlortetracycline or tetracycline are also obtained by (a) adding dibenzylethylene diamine to an already fermented broth which has been acidified and filtered or (b) adding dibenzylethylene diamine to an aqueous solution of tetracycline or chlortetracycline or (c) the tetracycline complex is obtained by hydrogenation of the chlortetracycline complex in the presence of palladium charcoal and a solvent at 1 to 3 kg/cm2 pressure, the mixture being maintained at neutral or slightly alkaline pH by addition of a tertiary amine, e.g. triethylamine. Tetracycline or chlortetracycline are recovered from their respective complexes by adjusting the pH to their respective isolectric points, e.g. with hydrochloric acid in a water-miscible organic solvent, e.g. methoxy ethanol or ethoxy ethanol and adding water to complete precipitation.  The tetracycline or chlortetracycline is recovered as an acid addition salt by reacting their respective complexes with an acid, e.g. hydrochloric acid in the presence of an organic solvent, e.g. methanol, ethanol, isopropanol or butanol or a mixture thereof together with methoxy ethanol or ethoxy ethanol.  In the presence of sodium chloride the acid addition salt of the complex is formed.  By use of these processes tetracycline or chlortetracycline may be recovered from waste mother liquors.ALSO:An animal feed, e.g. soya meal, comprises a supplement of dibenzylethylenediamine chlortetracycline or dibenzylethylenediamine tetracycline, or both (for preparation see Group IV (b)).

The carrier B is of inverted U-shape provided with knifeedges b<2>, b<3> resting upon V-blocks a<2>, a<3> on a frame A, the base A of which has two spirit-levels at right-angles to each other to ensure that the base is horizontal. The limbs b<4>, b<6> of the carrier carry extensions b<5>, b<7> forming journals for a sliding weight C and a stepped sleeve E which latter receives the body D to be balanced. The journals b<5>, b<7> are coaxial, the bars being parallel to and slightly below the axis of the knife-edges. The frame A is fitted with rectangular yokes a<4>, a<5> which limit the angular movement of the carrier, and a scale is carried by an arm a<6> attached to the yoke a<5>, a pointer b<8> on the carrier working over the scale. The pointer b<8> carries a small pointer b<9> and the carrier has two lateral extensions b<10>, b<11> carrying an adjustable scale pan F and an adjustable weight b<12> respectively. A pointer a<8> is supported by the base A at approximately the line of the knife-edges. Normally, with the base A<1> horizontal, and the pointer b<8> at zero, the pointer b<8>, the pointer b<9> and the axes of the knife-edges and journals lie in the same vertical plane. To use the apparatus, the body D is placed a friction fit on the sleeve E and the weight C so that the pressures in the knife-edges are approximately equal. The body D is then turned relatively to the journal b<7> until the pointer b<8> reads zero. A mark is then placed under the pointer b<9>. The carrier is held and the body D turned until the mark lies opposite the pointer a<8>. The scale-pin F is then adjusted so that its medial plane touches the periphery of the body D at the mark, and the weight b<12> is moved over its scale to balance. Weights are then placed in the scale pan until the pointer b<8> reads zero. This represents the. mass to be added at the marked point to balance the unbalanced force acting on the body D.
