Abstract: 959,393. Electromechanical filters. PHILIPS ELECTRICAL INDUSTRIES Ltd. Sept. 15, 1960 [Sept. 18, 1959], No. 31810/60. Heading H3U. An electromechanical filter is provided with a rotationally symmetrical mechanical system having additional resonators between the transducers and the support points to produce peaks of attenuation at the limits of the band-pass. The system comprises half-wave cylindrical resonators r coupled by quarter-wave rods k and is driven either in a torsional mode by a pair of phase-opposed transducers t 1  or in a longitudinal mode by a winding around resonator r 1 . The transducers are mechanically and electrically tuned. The output transducers t 2  are similar to the input transducers. Peaks of attenuation at either or at -both limits of the band pass are produced by additional resonators R 1 , R 2  between the transducers and the support points of the system, these being one half-wavelength long at the attenuation frequencies. Quarter-wave resonators L 1 , L 2  may be interposed between the transducers and the resonators R 1 , R 2  and also (not shown) between the resonators r. Slight variation in the dimensions of the resonators r may be used to flatten the band pass characteristic. The diameter of the resonators r 1  is preferably made 20% smaller than that of the resonators r.

Abstract: 1303038 Pleuromutilin derivatives BIOCHEMIE GmbH 1 July 1970 [2 July 1969] 32020/70 Heading C2A Novel pleuromutilin derivatives having the general Formula I wherein R is or hydrogen, are prepared by (a) cultivating Clitopilus passeckerianns (Pil.) Sing. NRRL 3100 or NRRL 3279, Clitopilus prunulus (Scop. ex Fr.) Kummner NRRL 3473, Clitopilus pinsitus (Fr.) ss. Romagn. Joss. NRRL 3474, or a, compound of Formula I-producing mutant or variant of one of these micro-organisms, under aerobic conditions in an aqueous nutrient medium containing assimilable sources of nitrogen and carbon and isolating the resulting compounds of Formula I; or (b) when R is hydrogen in Formula I, enzymatically acetylating mutilin of Formula II with one of the aforesaid micro-organisms or the dry mycelium or an enzyme extract thereof and isolating the resulting mutilin 14-acetate. Process (a) is preferably performed in the presence of a source of the fatty acid R groups, e.g. maize oil, sunflower oil, olive oil, or sperm oil in an amount of 0À5-5% of the medium. The products may be isolated from either the mycelium or the medium, e.g. by extraction with methanol or ethyl acetate respectively. The methanol extract is back-extracted with petroleum ether and this extract then concentrated and subjected to phase distribution between petroleum ether and methanol to give fractions containing the fatty acid esters and fractions containing mutilin 14-acetate. The latter is purified on a silica gel column by elution with CHCl 3 ,and the product is precipitated from the eluate by adding diisopropyl ether. The fractions containing the fatty acid esters are dehydrated and precipitated by adding hexane, taken up in diisopropyl ether and purified with active carbon. The percentage composition of the mixture is determined by methanolysis (methanolic KOH) to give the methyl esters of the component fatty acids, which are separated by gas phase chromatography. The mixture of methyl esters is also hydrogenated and hydrolysed and the resulting saturated acids examined by paper chromatography. Process (b) is preferably performed using the mycelium of Clitopilus passeckerianus NRRL 3100 in phosphate buffer pH 6À5 containing maize oil as a carbon source, a nitrogen source being unnecessary. Animal feed compositions comprise a ready mixed feedstuff together with a pleuramutilin derivative of Formula (I) above.

Filed: 1919-12-29
Abstract: 162,341. Rand, F. R., and Sanders, T. H. Dec. 29, 1919. Couplings, automatic.-In an automatic coupling comprising a coupling hook and a link arranged side by side and carried by an equalizer bar upon the vehicle, the hook upon one vehicle being adapted to be coupled to the link upon the other to effect a double coupling, disengagement of the hook from its opposing link is made by a manually operated eccentric which is returned to its normal operative position by the uncoupling of the vehicles. To each end of a short equalizer bar c, which is pivoted on the draught hook of the vehicle, a hook a and a link b is pivoted. A framework e under the hook has an inclined surface j which acts as a guide for the opposing link b when coupling. A cam d which can raise the hook a for uncoupling, is pivoted at h and is connected by a wire f to a drum on a transverse shaft i. When the vehicles meet, the opposing link b slides up the inclined surface of the framing e and raises the hook a which drops behind the link. To uncouple, the hook a is raised by the cam d until the recess g engages with the point of the hook. On the separation of the vehicles, the links disengage from the hooks and at the same time the cams are revolved by the links and drop into the position for the next coupling. The cam d may be operated by a system of links, and the link b may be of triangular shape, the side opposite the pivot of the link being inclined towards the side of the vehicle. The coupling may also be applied to the central type of buffing gear.
