Title: Improvements in universal joints for power-transmission systems
IPC: F16D3/78
Filed: 1922-07-06
Abstract: 200,691. Jelley, H. July 6, 1922. Universal joints.-A disc or ring, made from layers of rubber and canvas &c. or by moulding and vulcanizing fiberized rubber, e.g. by the method described in Specification 164,895, is bolted between spiders on the driving and driven shafts, the spider bolts passing through reinforcing bosses formed on the disc. Preferably these bosses are chamfered so that the rigidity of the disc diminishes gradually outwards therefrom, and their crowns are of equal diameter to the bolt washers and spider bosses, the edges of which parts are prevented by the bosses from chafing the body of the disc. Barrel-shaped or other bushes of vulcanite or similar semi-rigid material may be vulcanized in the bolt-holes, such bushes increasing the local rigidity and preventing distortion of the bosses under compression. Whether the body of the disc is made of homogeneous fiberized rubber or of layers of rubber and canvas, the bosses may be built up of layers comprising rubber and canvas rings decreasing in diameter outwardly from the disc. Additional local pressure may be applied to the crowns of the bosses in order to squeeze out the rubber and leave practically solid fabric around the bolt-holes. Specification 188,191 also is referred to.

Title: Process for preparing flavinadenine dinucleotide and reduced-form thereof
IPC: C12P25/00
Filed: 1955-07-05
Abstract: The invention comprises reduced form flavinadenine dinucleotide having a m.p. 222-225 DEG  C. (decomp.) and such a solubility that ca. 650 mg. of the substance dissolves in 100 c.c. of water at 20 DEG C., and a process for the purification of flavinadenine dinucleotide which is characterized by reducing the flavinadenine dinucleotide in an F.A.D.-containing substance, recovering the resulting reduced-form flavinadenine dinucleotide, and oxidizing the reduced-form flavinadenine dinucleotide-containing substance to produce flavinadenine dinucleotide.  As the flavinadenine dinucleotide-containing substance there may be used an extract obtained by cultivating a Vitamin B2-producing fungus, e.g. Eremothecium Ashbyii, Ashbya Gossippi, and extracting the mycelium separated after cessation of increase in weight of the mycelium with water or an aqueous solvent, e.g. lower aliphatic alcohols or ketones, and pyridine, at a pH near neutrality.  Additionally the F.A.D. fraction from liver may be used.  The reduction may be effected chemically, e.g. with agents furnishing the ions of S2O4-, Cr++, V++ or Ti+++, with nascent hydrogen, or with H2S, catalytically, e.g. with hydrogen in the presence of activated Pd, Pt or Ni, electrolytically (see Group XXXVI), or biochemically, e.g. with a reductase.  The reduced-form F.A.D. precipitates out and is filtered.  Oxidation of the reduced-form F.A.D. may be effected with air or hydrogen peroxide, FeCl3, H2SeO3, ClO-, chloride of lime, MnO2, S2O4-, MnO4-, MnO4-, CrO4-, Cr2O3 and Fe2(SO4)3.  The process is exemplified in detail.
