Title: Improvements in the manufacture of substantially anhydrous sodium soap lubricating greases
Filed: 1947-03-20
Abstract: Substantially anhydrous sodium soap lubricating greases, said to be mechanically stable, contain 0.01-1 per cent, and preferably 0.1-0.3 per cent, by weight of a polyalkylene glycol of mol. wt. over 200 or of an ester or an ether, especially a mono-ester or a mono-ether, of a polyalkylene glycol having a mol. wt. over 150.  The sodium soap content of the grease may be about 1-50, and preferably 3 1/2 to 7 1/2 or 10, per cent by weight, and the alkylene group of the glycol compound may contain 2-6 carbon atoms.  The polyalkylene glycol may be a mixture of several polymers and the molecular weight in this case refers to the mean molecular weight of the mixture.  The glycols used may be the polyethylene glycols, the polypropylene glycols, the polybutylene glycols, the polyamylene glycols, or the polyhexylene glycols.  Alternatively the mono-esters of these glycols, e.g. the fatty acid mono-esters, such as polyethylene glycol mono-stearate, may be used as well as the aromatic ethers of the glycols.  In an example, 200 grams of stearic acid, 35 grams of hydrogenated castor oil, 10 grams of polyethylene glycol (1500 mol. wt.), 25 grams of sodium hydroxide and 5700 grams of naphthenic mineral lubricating oil are mixed together at about 360 DEG  F. until the fatty components are completely saponified and all water of reaction substantially eliminated.  The molten grease is then poured to a depth of 1/2 inch in a pan and rapidly cooled in a stream of cold air.  Saturated fatty acids containing 14-32 carbon atoms in the molecule or unsaturated fatty acids containing 18-22 carbon atoms in the molecule may be used for preparing the sodium soap present in the grease, e.g. 12-hydroxy stearic acid, 10-dihydroxy stearic acid, 4-hydroxy palmitic acid, iso-stearic acid, iso-palmitic acid, ricinoleic acid, oleic acid, linoleic acid, hydrogenated fish oil fatty acids, palm oil fatty acids, cottonseed oil fatty acids, abietic acid and/or its glycerides and/or naphthenic acids.  Metallic sodium may be used as a saponifying medium.  Instead of the fatty acids, the glycerides or the lower monohydric alcohol or wax alcohol esters of these acids may be used in the manufacture of the grease. During the cooking of the sodium soap greases of the invention up to 2 per cent by weight of an aluminium and/or calcium soap may be added, and after cooking and cooling the greases may be mixed with any proportion, e.g. 1-70 per cent of aluminium and/or calcium soap greases.  Specification 622,945 and U.S.A. Specification 2,445,935 are referred to.  The Specification as open to inspection under Sect. 91 comprises also anhydrous sodium soap greases containing from 0.01-1.0 per cent by weight of polyalkylene glycol having a molecular weight in excess of 150.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in Rotary Electric Machines.
Inventor: NOBUHARA KANTARO
IPC: H02K5/12
Filed: 1918-05-16
Abstract: 116,886. Nobuhara, K. May 16, 1918. Armatures and field magnets, cooling; dynamos and motors, cooling. - In dynamo-electric machines of the kind wherein the stator and the rotor are immersed in a cooling- liquid, this liquid is kept out of the clearance space between the stator and the rotor by means of a gas under pressure. In the construction described, the stator 9 is surrounded by a casing divided into two chambers 24, 37 connected respectively to the delivery and suction sides of a rotary gas pump 20 operated by a pinion on the shaft 3 of the machine, From the chamber 24 the gas passes through an upper duct 25 in the stator, through the clearance space between the stator and the rotor, through a duct in the lower part of the stator to a float-chamber 26, then it passes by a pipe 29 and through a coil, (not shown), which acts as a cooling-device and as a resistance, and enters the upper part of the chamber 37. The gas is distributed through the stator by metal strips E curved as shown in Fig. 2. The cooling- liquid is circulated by a rotary pump 20' which delivers it into the compartment 38 occupied by the stator windings 18 on the left side of the machine, and the liquid passes from this compartment through numerous ducts in the stator, arranged parallel to the shaft 3, to the compartment 39 occupied by the windings at the right side of the machine, this compartment being open at the top to the gas chamber 37. A part of the liquid passes from this compartment direct to the suction pipe 23<1> of the pump, and the remainder flows through an aperture in a plate 13, which supports one box of the packing by which the liquid is prevented from reaching the periphery of the rotor, and through an axial passage to the rotor, which it traverses either through passages in the laminations or through hollow conductor bars 17. From the rotor the liquid passes through a passage in the shaft 3 to a collector 21 and to the pump 20<1>. When the apparatus is idle and liquid leaks into and fills the space between the stator and the rotor, a float-valve 27 in the chamber 26 is opened whereby the liquid is pumped out again when working is resumed, and the gas forced in assists to eject this liquid until the pipe 29 is uncovered, whereupon the valve 27 closes. If excessive pressure is reached by a circulation pipe becoming blocked, a valve 31 between the chambers 24, 37 opens and balances the pressure between the delivery and the suction sides of the pumps, The column of liquid in the chamber 37 is balanced against one in a pipe 40 which is surmounted by an expansible chamber 34, and if an excessive accumulation of gas occurs in the chamber 37, as by evaporation of the cooling-liquid, it escapes by the pipe 40. According to the Specification as open to inspection under Sect. 91 (3) (a), the main bearings of the machine are divided as shown in Fig. 1 and formed as part of chambers in the end covers 2, which are filled with lubricating-oil. This subject-matter does not appear in the Specification as accepted,
