Title: Rotary Positive-displacement Fluid-machines
IPC: F04C15/00
Filed: 1979-02-12
Abstract: A reversible gerotor pump has a reversing eccentric (40) for maintaining a constant pumping direction irrespective of the direction of rotation. The eccentric (40) is seated with a bearing surface (42) thereof, upon a bearing surface (62) provided in a housing member (14) and is frictionally coupled to a rotary outer gear (52) so as to be properly positioned thereby upon each reversal of rotation. In order to minimize the risk of sticking of the eccentric (40) there is means e.g. protrusions (80), limiting the area of direct frictional contact between the two fiat bearing surfaces (42, 62) to substantially less than the total area of the bearing surface (42) of the eccentric, and positively maintaining a lubricant- receiving space between said bearing surfaces. Alternatively, the protrusions are formed on a plate (60). <IMAGE>

Patent GB-794632-A (GB)
Abstract: 794,632. Diglycidyl ethers of diols. BADISCHE ANILIN- & SODA-FABRIK AKT.- GES. May 2,1956 [May 14, 1955], No. 13498/56. Class 2 (3). Diglycidyl ethers of diols with two primary hydroxyl groups are produced by reacting a diol having two primary hydroxyl groups in the presence of an acid catalyst first with 0.5 to 1 mol., preferably 0.65 to 0.85 mol., of an epihalogenhydrin at an elevated temperature above about 40‹ C., distilling off unreacted diol, then heating again with a further 0.3 to 0.7 mol., preferably 0.35 to 0.55 mol., of epihalogen hydrin and finally preparing the diglycidyl ether from the diol dihalogenhydrin ether thereby formed by reacting with basic compounds by methods in actual use or described in the literature on the subject. The diol starting materials may be aliphatic, cycloaliphatic or aromatic and may contain hetero atoms, e.g. oxygen. They may be substituted by alkyl, cycloalkyl, or aryl radicals, or electronegative substituents such as chlorine or bromine. Suitable diols are ethylene glycol, 1,3-propylene glycol, 1,4-butane-diol, 1,6-hexane-diol, beta-glycerine chlorhydrin, and also polyglycols, such as di- or tri-ethylene glycol, as well as terephthalic alcohol, 1,1- dimethyl-1,1-dimethylol-methane or chlorinated dimethylol cyclohexanes. The epihalogen hydrin may be epichlorhydrin or epibromhydrin. Suitable acid catalysts are acid metal salts such as Friedel-Crafts catalysts, e.g. aluminium chloride or boron trifluoride, or their ethers, or inorganic acids, e.g. sulphuric, boric or phosphoric acid. In the first stage of the process, the reactants are heated at about 50-110‹ C. until epoxy groups are practically undetectable in the mixture, the unconverted diol is distilled off and the monochlorhydrin ether formed is reacted with epihalogenhydrin in the second stage of the process to form the diol-halohydrin ether. The latter, after distillation, if desired, is reacted with basic compounds such as aluminates, zincates, silicates, or alkali hydroxide, preferably with an alcohol, e.g. butanol, or a hydrocarbon, e.g. toluene, with cooling, preferably at temperatures of about 0‹ C. The diglycidyl ethers are valuable for the production of plastics, synthetic fibres or lacquers, or as pharmaceuticals. In examples: (1) ethylene glycol and epichlorhydrin are reacted in the presence of boron trifluoride in accordance with the two stage process, then the chlorhydrin ether is stirred with caustic soda and toluene and the product is distilled to give glycol diglycidyl ether with glycol monoglycidyl ether as a by-product; (2) 1,4-butane diol is similarly converted to butane diol diglycidyl ether and monoglycidyl ether. Specification 672,935 is referred to.
