Patent GB-401237-A (GB)
Title: Process for the manufacture of new condensation products
IPC: C08G8/00
Filed: 1933-07-06
Abstract: Condensation products are manufactured by reacting phenols or derivatives thereof with unsaturated fatty acids or derivatives thereof in the presence of boron fluoride, if desired in the presence of a solvent which does not react under the prevailing conditions, e.g. hydrocarbons such as benzine, benzene, toluene or xylene, also chloroform or carbon tetrachloride.  Suitable fatty acids and derivatives are: the unsaturated higher fatty acids occurring as glycerides in natural fats and oils; drying fatty oils; conversion products of fatty oils, e.g. the products known as boiled linseed oils (stand oils), obtainable on polymerization by heating, if desired, in the presence of a catalyst.  The reaction generally proceeds most advantageously at room temperature, but higher temperatures may be employed, suitable temperatures being 10-80 DEG C.  The products are obtained in the form of a viscous liquid or a pronouncedly adhesive mass which can be drawn into threads, or as a rubber-like mass.  In examples: (1) boron fluoride is introduced by means of a current of nitrogen into a mixture of olive oil and cresol mixture at room temperature, whereupon the temperature rises to 45 DEG  C.; after standing overnight the mixture is diluted with benzene, the boron fluoride is decomposed by means of sodium carbonate, the product is filtered and the benzene and undecomposed cresol distilled off; (2) linseed oil for lacquer is similarly condensed with cresol mixture; (3) oleic acid is similarly condensed with commercial cresol; (4) technical linseed oil fatty acid and cresol are similarly condensed; (5) linseed oil for lacquer is similarly condensed with anisole.

Title: Production of filled polyimide resin coatings on internal cylindrical surfaces
IPC: B29C63/26
Filed: 1969-04-16
Abstract: 1,249,026. Polyimide coated cylindrical surfaces. GENERAL MOTORS CORP. 16 April, 1969 [16 July, 1968], No. 19460/69. Heading B2E. A filled polyimide resin coating having a thickness of 30-40 mils is produced on an internal cylindrical surface by heating a mixture of a filler and a polyimide precusor solution to 150-180F, rotating a cylindrical member to be coated about its longitudinal axis and heating it to approximately the same temperature as the mixture, casting the mixture on to the internal cylindrical surface of the rotating member to form a coating of substantially uniform thickness, slowly heating the coating to a second elevated temperature greater than the first elevated temperature so that the solvent is evaporated and the resin partially cured so as to be self sustaining without the formation of voids or blisters in the coating, stopping the rotation, slowly heating the coating in an inert, gas atmosphere, e.g. argon, under a pressure which at the start of heating is 2 to 6 times normal atmospheric pressure to a third elevated temperature greater than the second elevated temperature to permit evolution of residual solvent and volatile curing reaction by products without blistering of the coating, removing the inert gas and volatile materials and heating the coating to a fourth elevated temperature greater than the third elevated temperature to complete the curing of the resin so that a smooth, void-free coating of thickness 30-40 mils is produced. The polyimide resin may be produced by the reaction of an organic tetracarboxylic acid or acid dianhydride and an organic primary diamine, the solvent may be xylene or N-methylpyrrolidene and the filler which may be used in the proportion of 2-3 parts by weight of filler to one part by weight of polyimide precusor, may be talc, mica, silica, alumina, graphite or a mixture thereof. During heating while rotating the rotational speed may be increased at a given temperature to accomplish moulding but decreased before further heating to avoid migration of the filler in the warm and initially less viscous resin. During beating under pressure in an inert gasa temperature of 350-360 may be attained, the volatile materials being periodically vented during heating, and final heating may be effected at 580-620F. Turbine compressor rings may be coated.

Filed: 1920-07-09
Abstract: 148,193. Chovin, A. Sept. 9, 1918, [Convention date]. Foundry ladles. - In tilting apparatus for metallurgical &c. vessels, in which longitudinal movements is imparted to the trunnion bearings, the means for compensating the rearward or forward movement of the spout are adapted to be thrown out of operation to facilitate cleaning. Fig. 1 is a front elevation of the device. On one of the trunnions b of the vessel a is carried a large worm wheel e into which gears the worm g. The trunnion bearings c have dovetailed ribs slidably engaged in guides in the bearing blocks d, and may have cover-plates p to exclude dirt. On the trunnions are fixed toothed segments i gearing into racks k rigidly mounted on the blocks d. The radius of the segments is such that when the vessel is tilted by means of the motor l actuating the worm gear, and the bearings c move horizontally by the engagement of the segments with the racks k, a vertically downward motion is given to the spout n. To disengage the racks k to allow for complete rotation, the lever r is turned to move over the cams s on which the racks rest. The Specification as open to inspection under Sect. 91 (3) (a) describes also another arrangement in which connecting-rods t, Fig. 3 (Cancelled), are pivotally connected to the arms u of the blocks d and to the vessel. The length of the rods and position of the pivot determine the path of the spout. Removal of the bolts v permits of complete rotation. In another modification, guidespindles rotated by spur wheels from the worm gear engage in projections on the bearings c and are of such a pitch as is required to direct the spout to the point desired. This subject-matter does not appear in the Specification as accepted.
