Title: Aminoplast-polyester condensation products
IPC: D06P1/44
Filed: 1959-02-27
Abstract: A condensation resin is obtained by simultaneous reaction of (A) 40-65% of an alkyd containing OH groups and having an acid number of 3-7.  (B) 20-35% of an etherified aminoplast and (C) 15-25% of a polyester.  The alkyd (A) has a molecular weight of 2,000-10,000, and is water-insoluble but soluble in butanol, pentanol or the monoethyl ether of ethylene glycol.  It may be oil or oil acid-modified. Lists of suitable ingredients are given.  They may include alcohols with at least three OH groups and unsaturated dibasic acids.  Component (B) is prepared from formaldehyde and urea, thiourea, imidazolidinone-2, aminotriazines or alkyl substituted aminotriazines.  Alkylation is effected with an alcohol having 3-6 carbon atoms.  The alkylated product is water-insoluble and so hydrophobic as to be not self-despersible in water.  It is soluble in alcohols.  Component (C) which may be prepared as in Examples 1-12 of the parentSpecification is a low molecular weight (800-1,500) polyester containing hydroxyl and carboxyl groups.  It has an acid number of 90-120, and is prepared by reacting ophthalic acid or its anhydride or a derivative thereof containing alkyl substituents of 1-4 carbon atoms with a polyester having an acid value below 10, formed from 1 mol of a dibasic acid of 5-10 carbon atoms and 1,2-1,8 mols. of a mixture of a diol and at least 25 mol % of a polyol having at least three hydroxyl groups.  Conventional ester-forming procedures are employed and are described at some length.  The intermediate polyester for component (C) may be modified with a fatty acid having 8-30 carbon atoms or with a fatty oil.  Components A, B and C are reacted together in organic solvents until the viscosity at room temperature and 60% solids has risen by 20-30 poises.  The cooled reaction mixture may be neutralized with ammonia an amine or a quaternary ammonium compound. The products may be diluted with water for use as coatings, adhesives or impregnants.  They may be used as described in parent Specification for clear coatings, impregnants or adhesives or may be pigmented.  In Example 1, a 60% solution in xylene of an alkyd having an acid number of about 5 and derived from 44% phthalic acid, 20% glycerol and 36% of an equimolar mixture of myristic and capric acids, is mixed with a 60% n-butanolxylene solution of an n-butylated methylol melamine and with the polyester solution obtained in Example 6 of the parent Specification.  The mixture after short agitation at room temperature is heated at 55 DEG -65 DEG C., cooled and neutralized with triethylamine.  The salt is self-dispersible in water.  Titanium dioxide was dispersed in the aqueous composition to yield a sprayable coating composition suitable for application to a bonderized steel panel.  Mixed with copper phthalocyanine blue and small quantities of ammonia, sodium alginate and t-octylphenoxy-polyethoxyethanol containing about ten oxyethylene units it yields a pigment dye bath suitable for padding on to cotton fabric.

Abstract: 1,083,246. Clamps; remotely operated fastenings. INSTRON CORPORATION. Feb. 16, 1966 [May 21, 1965], No. 6891/66. Headings E2A and E2B. [Also in Division G1] Apparatus for materials testing comprises a grip 10 having a frame 12, first and second jaws 18, 20 constituting a pair of clamping jaws supported by said frame for receiving a specimen, said first jaw 18 being movable between a retracted position and a clamping position in which it bears against the specimen, low pressure means for biassing said first jaw against the specimen when said first jaw is in its clamping position and means for the application of high clamping pressure against the specimen while said first jaw is in its clamping position. In the construction shown the jaw 18 is mounted on a shaft 42 disposed in a jaw actuator 44 and retained therein by a vertical pin 46. The jaw actuator 44 is contained in a stepped cylindrical bore 48 of the frame which is closed at its left hand end by a pressure cap 50 and between the cap and the jaw actuator 44 is a second jaw actuator 80. The jaw 18 is moved into contact with the specimen by a spring 78 which is trapped between the two actuators 44 and 80 and to release the jaw from the specimen pressurised air is supplied to a passage 74 and bears against a flange 67 of the actuator 44 to counteract the pressure of the spring and release the jaw 18 from the specimen. In use the specimen is positioned between the jaws, air pressure is released to allow the spring to move the jaw 18 against the specimen and then oil under high pressure is admitted to the recess between the cap 15 and the actuator 18 which forces the actuator 80 to the right against the actuator 44 to increase the pressure of the jaw 18 on the specimen. The jaw 20 is carried by a shaft 22 disposed in a vertical slot in a jaw holder 24 and retained therein :by a horizontal pin 26; the jaw holder 24 is disposed in the cylindrical bore 28 in a frame portion 16 and is prevented from rotation by a dowel 30. An adjusting screw 34 is rotatably mounted in the frame and is threaded into the jaw holder 24. The operation of the grip is controlled by solenoid operated three-way flap valves which in turn are controlled by foot switches. The flap valves supply air to the jaw actuator 44 and also air to a hydraulic booster which supplies oil at high pressure in the jaw actuator 80. The arrangement is such that air can only be supplied to the hydraulic booster when the air pressure has been removed from the jaw actuator 44.

Title: Improvements in or relating to the manufacture of silicon nitride and oxynitride
IPC: C01B21/068
Filed: 1962-02-24
Abstract: Silicon nitride, oxynitride or mixtures thereof are prepared by heating silicon, a silicon alloy or a silicon-providing compound in an atmosphere of nitrogen or at least one nitrogen-providing gas, at 1000-1900 DEG  C. in the presence of more than 5% by weight of an alkali metal, an alkaline earth metal (including magnesium) or a metal having atomic number 21-30, 39-48 or 57-79 (all inclusive). The catalyst metal may be used as such or as an alloy or compound, e.g. the oxide, hydroxide, carbonate, nitride, nitrite, nitrate, acetate or oxalate.  The catalyst metal may also be alloyed with the silicon or present as the metal silicate. With silica or metal silicate, a reducing agent, e.g. carbon, is incorporated therewith, and the relative proportion of carbon determines the composition of the product in terms of silicon nitride and/or silicon oxynitride, or silicon carbide.  Reaction may take place in a continuously rotated or vibrated furnace with the reaction mixture in particulate form. Alternatively, the silicon, silicon alloy or other silicon providing substance and the catalyst are initially heated with an organic binder, e.g. sugar, molasses, starch, pitch or tar, which also provides reducing carbon. The reaction mixture may include an inorganic substance which evolves gas on heating, e.g. ammonium nitrate, to increase its porosity.
