Title: Lubricating and Cooling System for Electric Motors, Particularly as Used in Enclosed Refrigerating Compressors.
Inventor: TRENKOWITZ GERHARD
IPC: H02K7/08
Filed: 1967-02-06
Abstract: 1,157,533. Enveloping dynamo-electric machines in special media; cooling; lubricating; mounting. BROWN, BOVERIE & CIE, A.G. 6 Feb., 1967, No. 5612/67. Heading H2A. In a lubricating and cooling system for electric motors, particularly for enclosed refrigerating compressors, the medium is withdrawn in the liquid state from a condenser, is fed in a forced circulation system to the bearings of the motor to serve as a liquid lubricant, is then vaporized in the interior of the motor by absorbing the waste heat, and is returned to the condenser through an air gap and ducts of the motor as shown, applied to the motor driving a refrigerating compressor 10, some of the refrigerant vapour is bled off the delivery at 12, condensed at 1, and discharged as liquid by diaphragm pump 3 along parallel paths to both bearings 4 of the rotor to lubricate them. Some liquid returns to the compressor 10, but most is vaporized by waste heat in the spaces 5 of the motor, and is withdrawn, by temperature gradient, along the air gap 6, and axial and radial stator passages 7, 8 respectively, to the condenser 1. Preferably the condenser 1 is that used in the main refrigeration cycle. In an embodiment of broader scope, the compressor 10 and bleed line 12 are omitted, and a liquidtight seal is provided where the driving end of the rotor shaft emerges from the motor housing.

Patent GB-706599-A (GB)
Title: Improvements in the reaction of carbon monoxide with hydrogen to form alcohols
IPC: C07C29/16
Filed: 1952-03-07
Abstract: A process for the production of alcohols, in particular isobutyl alcohol, by the reaction of carbon monoxide and hydrogen at temperatures of from about 300 DEG  to 500 DEG C. and at pressures above about 50 atmospheres consists in using catalysts containing oxides of metals of the Group IV (a) of the periodic system which contain 0.5 to 10 per cent. of alkali and leading about 1,000 to 10,000 volumes (at normal conditions) of the mixture of gases into the reaction chamber per hour per volume of catalyst.  Oxides of zirconium are especially suitable as catalysts and activating oxides of trivalent metals may be added thereto, e.g. oxides of indium, gallium, aluminium or trivalent chromium.  Zirconium oxide together with indium oxide and potassium oxide is especially suitable and alkalies other than potassium oxide may be used, e.g. rubidium oxide. The catalysts are preferably prepared from aqueous solutions of salts of metals of Group IV (a) of the periodic system by precipitation with alkalis, e.g. potassium hydroxide, potassium carbonate or ammonia.  The filtered and washed precipitate may contain sufficient alkali or this may be added, e.g. by allowing the dry catalyst to absorb the alkali from a solution or by evaporating an alkali solution into which the catalyst has been introduced.  The catalysts may be heated in the presence of oxygen or hydrogen before use and carriers, e.g. alumina may be employed.  In examples: A product containing methyl alcohol, isobutyl alcohol, alcohols of higher boiling point and other oxygen containing compounds is obtained by passing a mixture of carbon monoxide, hydrogen and nitrogen at elevated temperature and pressure through a copper lined reaction tube containing a catalyst obtained by mixing solutions of zirconium nitrate, indium nitrate and caustic soda in water and filtering, washing and drying the product (1); and in a similar process a catalyst obtained by precipitating litanium dioxide hydrate from an aqueous solution of potassium titanium oxalate with potassium hydroxide solution and washing and drying the product is employed.
