Title: Antibiotic a-28086 and process for production thereof
IPC: A23K20/195
Filed: 1975-06-04
Abstract: The novel antibiotic A-28086 complex containing the factors A, B and D is produced by culturing Streptomyces aureofaciens NRRL 5758 or Streptomyces aureofaciens NRRL 8092 in a culture medium, which contains assimilable sources for carbohydrate, nitrogen and inorganic salts, in submerged aerobic fermentation conditions until these organisms have produced a significant amount of antibiotic activity in the culture medium. The antibiotic is then separated off from the culture medium. The novel antibiotic can be dissociated into the factors A, B and D. These can be converted into the corresponding physiologically tolerated salts. The novel antibiotic can likewise be converted into C2-C6-acyl esters. The novel antibiotic A-28086 complex, the factors A, B and D, the physiologically tolerated salts thereof and also C2-C6-acyl esters thereof are used to increase the feed intake of ruminants. They can additionally be used for the prevention or treatment of coccidiosis in poultry.

Title: Improvements in or relating to a high-frequency multi-layer conductor
IPC: H01P3/18
Filed: 1953-08-31
Abstract: 734,160. Conductors. SIEMENS & HALSKE AKT.-GES. Aug. 31, 1953 [Sept. 4, 1952; Sept. 4, 1952], No. 24078/53. Class 36. A high-frequency multi-layer conductor of substantially circular cross-section is formed from one or more component multi-layer conductors of non-circular cross-section consisting of a plurality of alternate thin layers of metal and insulation. The conductor may consist of two 'semi-circular components 10, 11 formed around a core 12 and enclosed in a retaining band 13 and-water-tight sheathing 14. Where there are more than two components they may be of appropriate sector shape, and they may be arranged in more than one layer 19, 20 (Fig. 3). The component conductors may extend longitudinally or be twisted together, and each may be enclosed in an insulating layer. A sector-shaped component multi-layer conductor may be formed by means of rollers from a stack of flat foils or from a spirally wound assembly. In a further method (Fig. 15) an insulating strip 40 is provided with metal layers 41, 42, arranged alternately on opposite sides thereof and spaced from each other to leave gaps 43 along which the strip 40 may be folded. In a modification of this method the metal layers 41, 42 are formed opposite to each other, the gaps 43 then being such that on folding the strip the unmetallized parts thereof lie between metal layers. In either case successive metal layers may have increased width so that on folding a component multi-layer conductor of trapezoidal cross-section is produced. Two such component conductors 55, 56 (Fig. 24) may be passed through shaping devices 57, 58, and then passed, together with a core 44, through a shaping device 59 to produce a multilayer conductor. Such a conductor may be subdivided at the end to form two separate multi-layer conductors for branching purposes by separating the ends of the two component conductors 47, 48, removing the core 44 from the separated ends and then shaping them to form two conductors of substantially circular cross-section, each of which is finally enclosed in a waterproof covering.

Title: Improvements in or relating to friction clutches of the automatic centrifugal type
IPC: F16D43/18
Filed: 1920-08-19
Abstract: 171,198. Bailey, R. W., Miller, L., and Metropolitan-Vickers Electrical Co., Ltd. Aug. 19, 1920. Clutches, friction.-To ensure even wear in centrifugal segment clutches, the centres of gravity of the segments are arranged to fall between their trailing edges and the radial lines through the centres of their frictional surfaces. To this end, the weight of the segment D may be suitably arranged, for instance, as shown in Fig. 3, by prolonging the clutch surface at the leading edge, wearing-material K being secured by screws s &c. M, L not conflicting with the frictional area. To ensure correct positioning of the centre of gravity G, it is necessary that the drive from the driving-member A to the segments should be well defined, for which purpose driving-rollers E are used, or, as shown in Fig. 4, links Q connect pivot pins R, J on the segment D and on an arm F turning with the driving-member; in this form, the segment swings outwardly upon the pin R. In a modification, the pin J engages a radial slot at the centre of the segment D, a loose weight being also pivoted on the pin and swinging into contact with the trailing end of the segment whatever the direction of motion. In another construction, shown in Fig. 7, for shifting the centreof gravity according to the direction of drive, a weighted roller S slides or rolls on the flat orslightly curved surface D' of the segment D, or in grooves in its side walls, a retaining-recess T being provided at each end of the segment, and shock being prevented by cushioning-means U. A spring X adjusted in the segment by a screw Y and engaging at its ends with the member A may be provided to prevent clutch engagement below a minimum speed. According to the Provisional Specification, it is desirable that the force of the spring should be directed towards the centre of gravity of the block, and for that pur. pose, when the clutch is designed for drive in either direction, the spring is moved, or the point of application of its pressure is otherwise automatically shifted, as the drive is reversed.

Abstract: Monochloromethylpentamethyldisiloxane is prepared by continuously charging hexamethyldisiloxane into a reaction zone, continuously charging chlorine into said reaction zone, maintaining the rate of charging chlorine relative to the rate of charging hexamethyldisiloxane sufficiently low that hexamethyldisiloxane is maintained in the reaction zone continuously, and continuously removing chlorinated hexamethyldisiloxane from the reaction zone. The chlorine may be charged into the reaction zone in an amount less than sufficient to form monochloromethylpentamethyldisiloxane.  The temperature of the reaction zone may be maintained at a temperature below the boiling point of hexamethyldisiloxane whereby hexamethyldisiloxane and chlorinated hexamethyldisiloxane are continuously removed from the reaction zone, or may be maintained between the boiling points of the hexamethyldisiloxane and of the monochlor derivative whereby monochloromethyl pentamethyldisiloxane condenses upon formation, and unreacted hexamethyldisiloxane may be separately withdrawn from the reaction mixture.  The reaction zone may be exposed to a source of light. A catalyst may be employed if desired.  Flow diagrams are given for 4 vapour phase and liquid phase reactions.
