Title: Improvements in and relating to journal bearings
IPC: F16C33/10
Filed: 1956-12-12
Abstract: 845,710. Lubricating bearings. GENERAL ELECTRIC CO. Dec. 12, 1956 [Dec. 12, 1955], No. 37959/56. Classes 12 (1) and 12 (3). In a journal bearing 4, Fig. 1, for a shaft 3 arranged for rotation in both directions and having wick and slinger members 11, 13 disposed at points which are spaced in the axial direction of the shaft, oppositely - spiralled grooves 21, 22 are provided on the surface of the shaft between the wick and slinger members for pumping lubricant in opposite directions when the shaft is rotating and for reversing the pumping direc-. tions when the rotation is reversed, the said grooves having asymmetrical cross-sections, Fig. 2, so that the pumping action from the wick 11 towards the slinger 13 is the more effective independent of the direction of rotation. Preferably the crosssection of the grooves-is V-shaped with one side of the V being inclined, with respect to the radial direction, at a larger angle than the other. In an alternative arrangement the grooves are formed in the bearing surface 7 supporting the shaft 3. The bearing 4 comprises an outer shell 9, with an apertured radial plate 8 and a sleeve-member 6 for the bearing-surface 7, and end cover-members 19, 20, and arranged against the inner surface of the shell in alignment with the wick and slinger members are annuli 16, 15, respectively, e.g. of felt, the annulus 16 containing a liquid lubricant and both being preferably filled with a mass of absorbent material 18. In a modification, Fig. 3 (not shown), lubricant is supplied by a wick member to an intermediary point of the journal portion of the shaft, slinger members are disposed on the shaft on each side thereof, and a pair of oppositely-spiralled grooves are formed in the shaft between the wick member and each slinger member. The invention is stated to be particularly applicable to dynamo-electric machines.
Patent GB-985162-A (GB)
Title: Derivatives of the antibiotic decoyinine
IPC: C07H19/16
Filed: 1963-09-26
Abstract: The invention comprises decoyinine derivatives of formula <FORM:0985162/C2/1> wherein X is CH2 = or CH3-, R is H or -OR1 when X is CH3, and -OR1 when X is CH2 =, and R1 is hydrogen or a saturated hydrocarbon acyl radical of not more than 8 carbon atoms. Specified are 6-hydroxy-6-desaminodecovinine, 6-hydroxy-6-desaminodihydrodecoyinine, 6-hydroxy -6-desaminodeoxydihydrodecoyinine and the corresponding triacetates, tripropionates, tributyrates, tricyclopentylpropionates, triphenylacetates, tribenzoates and o-, m- and p-tritoluates. The compounds are produced by treating a compound of formula <FORM:0985162/C2/2> (wherein R2 is a saturated hydrocarbon acyl radical of not more than 8 carbon atoms) with nitrous acid and, if required, deacylating. Preferably an alkali metal or alkaline earth metal nitrite is added to an acid solution of the compound of formula II at 5 DEG  to 40 DEG  C.  Deacylation is by treating a methanol solution of the acylated compound with a base, e.g. ammonia or alkali metal hydroxide, at 0-10 DEG  C. or with a strongly basic anion exchange resin. Dihydrodecoyinine triacetate and deoxydihydrodecoyinine diacetate are produced by the catalytic hydrogenation of decoyinine triacetate, which is itself produced by treating decoyinine with acetic anhydride in pyridine. Other acylates may be prepared by treating the appropriate decoyinine derivative with an acid chloride or anhydride of the appropriate acid. The compounds are useful in solution or dispersed in plastic films as light filters.  6-Mercaptopurine may be prepared from 6-hydroxy - 6 - desamino-decoyinine compounds of formula I by treatment with phosphorus pentasulphide to produce the 6-mercapto decoyinine derivative followed by methanolysis to remove the sugar moiety. Methylation of the 6-mercaptopurine gives 6-methylmercaptopurine. Specification 935,075 is referred to.

Abstract: 854,314. Indicating liquid levels. COMPAGNIE DE SAINT-GOBAIN [formerly MANUFACTURES DES GLACES ET PRODUCTS CHIMIQUES DE SAINT-GOBAIN CHAUNY & CIREY S. A., DES]. Dec. 12, 1956 [Dec. 12, 1955], No. 38003/56. Class 123(1) The surface of separation between two immiscible liquids within a container is indicated by means of a body 1 suspended from a pulley 3 carrying a needle 5, the body being counterweighted by elements 4a and 4b so that it will assume a position of equilibrium, being partly immersed in the heavier liquid and partly immersed in the lighter liquid, the elements 4a and 4b being immersed, one in each of the liquids, and each having a volume equal to that portion of the volume of the body 1 which, in the equilibrium position, is immersed in the same liquid as that element. If the elements 4a and 4b and the body 1 are of different densities a further counterweight is carried by another pulley (not shown) fixed to pully 3. In a further embodiment, Fig. 2 (not shown), the body 1 is suspended from a larger diameter on the pulley 3 than that from which the elements 4a and 4b are suspended, thus increasing the difference between the maximum and minimum readings capable of being indicated. To increase the sensitivity of the apparatus, the body may be in the shape of two cones of equal volume united at their bases. The apparatus may be used for indicating the level of the separation surface between a liquid and a gas.
