Patent GB-1202692-A (GB)
Title: Bearing assembly
Inventor: FULLER JOHN RODNEY DYSON
IPC: F16C19/52
Filed: 1966-07-02
Abstract: 1,202,692. Bearings. ROLLS ROYCE Ltd. 29 Aug., 1967 [2 July, 1966], No. 29792/66. Heading F2A. A bearing assembly for a rotary shaft 16 includes a ball bearing 14 with an outer race 13 supported by oil in a space or "clearance" 17 associated with a fixed annular seating 11, rotation of said race being prevented by a spring 19, which under normal conditions holds a tooth 23 against a face 24 upon a fixed cover 12. Additional friction caused by wear partially rotates the race 13 to bring the tooth into abutment with a face 25, thereby increasing the rate of flow of lubricant to the bearing and producing a signal indicating impending failure. Normally oil is directed by a pump 27 through an annular groove 29, radial ducts 30 and orifices 31 into an annular channel 33 in a member 32 fixed to the shaft. Oil overflows into a space 35 whence it is forced into the bearing through radial ducts 37 by compressed air flowing through a labyrinth seal 39. When the tooth contacts the face 25 an outlet 47 in each of the ducts 30 is opened to increase the flow of oil into the channel 33. A switch 44 operates when the flow increases to provide the signal. Axial thrust is balanced by oil in a space 54, which is charged through a duct 55 extending into the channel 33. Oil leaking across an interface 52 escapes into the channel 30 through ducts (49), Fig. 2 (not shown). The oil in the space 17 absorbs vibrations.

Title: Improvements relating to modified aminoplastic resinous compositions
IPC: C08L61/20
Filed: 1954-10-18
Abstract: A modified aminoplast composition, particularly suitable for impregnating and laminating fibrous sheet materials, and as moulding material, comprises the uncured reaction product of an aldehyde and a monomeric compound containing at least two amidogen groups each having at least one hydrogen atom attached to the amidogen nitrogen, and an alpha-alkyl-d-glucoside, the alkyl group having 1 to 4 carbon atoms.  Specific examples are a -methyl-, a -ethyl-, and a -butyl-d-glucoside.  The preferred amidogen compounds are urea and melamine; others specified are methylmelamine, acetoguanamines, methyl-, phenyl-, allyl- and guanyl-urea, dimethylol urea and polymethylol melamines and their alkyl ethers, thiourea, phenyl- and guanyl-thiourea, dicyandiamide, guanidine, biguanide, diaminodiazines and guanazole.  The preferred aldehyde is formaldehyde; others include para-formaldehyde, hexamethylene tetramine, acetaldehyde, propionaldehyde, butyraldehyde, furfural and benzaldehyde.  The glucoside may constitute about 1 to 35 per cent by weight of the composition which is then water-dilutable.  Fillers which may be incorporated in the moulding compositions include alpha-cellulose, wood flour, walnut shell flour, calcine or natural asbestos, silicon carbide, carbon black, graphite, diatomaceous earth, slate dust, and ground cuttings, e.g. of silk, rayon, nylon, glass cloth and ground cork.  Curing agents may sometimes be used, e.g., phthalic acid and anhydride, p-toluene sulphonic acid and benzoyl peroxide, as well as mould lubricants such as zinc-, calcium- and glyceryl monostearate. For impregnation, the solutions may be aqueous, aqueous-alcoholic or aqueous-acetone.  Suitable alcohols are methanol, ethanol, isopropanol and tert-butanol.

Abstract: 346,358. Ironing presses. PROSPERITY CO., Inc., Beattie Street, Syracuse, New York, U.S.A.-(Assignees of Davis, E. ; 324, Roosevelt Avenue, New York, U.S.A.) Oct. 3, 1929, No. 30048. Convention date, Jan. 4. [Class 138 (ii).] The press head is brought into light contact with the buck when a source of low pressure fluid is brought into communication with the cylinder containing the piston which is connected to the press operating linkage, and an adjustable heavy pressure is applied between the press members by placing the cylinder in communication with a source of high pressure fluid. The low pressure fluid supply pipe 22, Fig. 2, communicates with a valve casing 21 through a normally closed inlet valve 23. The casing 21 is provided with a pipe 26 leading to the cylinder 9 and with a normally open exhaust valve 24 on a common stem 25 with the inlet valve 23. The valve 23 is opened by depressing a button 35 which acts on a lever 36 which in turn acts on a lever 39 mounted on a rockshaft 38 and acting on the valve stem 41. The button must be maintained depressed until after the piston 10 has passed a port 56 in the cylinder 9 whereupon fluid pressure acts on a diaphragm 50 to maintain, through a pin 51 and the lever 39, the exhaust valve 24 closed and the inlet valve 23 open. The high pressure pipe 30, Fig. 3, communicates with a valve casing 29 and is provided with a normally closed inlet valve 31 and a normally open exhaust valve 32. The casings 29, 21 connect through a pipe 45 containing a check valve 47 which checks the access of high pressure fluid to the piston 10 whilst the press is closing. The valve 31 is opened and valve 32 closed by the depression of the button 35, the arm 40 actuating the valve stem 42 being mounted on the same rock shaft 38 as the lever 39. The pressure is relieved by raising a lever 60, Fig. 2, to open a normally closed exhaust valve 57. To provide for the occupation of both hands of the operator during press closing an auxiliary exhaust valve 65 must be maintained closed by depressing a button 61 until after the piston has passed the port 56 whereupo the valve 65 is maintained closed through the diaphragm 69, pin 70 and lever 63. Additionally the initial closing of the press may be effected mechanically by the operator by depression of a treadle connected to the press head lever.

IPC: C23C18/52
Filed: 1964-07-31
Abstract: Silver, mercury, copper or gold salts are alkylated, arylated, alkenylated or reduced with an organo-trifluorosilane preferably in the presence of an acid, particularly hydrofluoric acid.  Other organo-silanes may be used in the presence of hydrofluoric acid if they are convertible to organo-trifluorosilanes.  The organotrifluorosilane may be added dropwise, or passed as a gas, into a solution of the salt in an organic solvent, alcohol being present if required to aid solubility.  In the case of mercury salts, where HF is present, ammonium chloride is added to dissolve by-product mercury fluoride.  Examples describe the preparation of (1) phenylmercuric chloride from mercuric chloride and phenyltrichlorosilane in the presence of HF, (7) methylmercuric chloride from mercuric chloride and methyl trifluorosilane and (8) a silver mirror from silver nitrate and methyl trifluorosilane in water acidified with HF, or, in alcohol solution a black precipitate of finely divided silver.ALSO:A silver mirror is produced by passing mernyltrifluorosilane into an aqueous solution of silver nitrate acidified with hydrofluoric acid.  In alcoholic solution, the silver separates as a finely-divided black precipitate.
