Title: Aqueous dispersions of thermosetting copolymers suitable for electrophoretic deposition
IPC: C09D167/00
Filed: 1967-10-02
Abstract: 1,204,877. Aqueous polymer dispersions. DESOTO Inc. 2 Oct., 1967 [6 Oct., 1966], No. 44727/67. Heading C3P. [Also in Division C7] Aqueous dispersions suitable for electrophoretic deposition comprise a salt of a base with a copolymer formed by solution copolymerization of monomers including a monoethylenically unsaturated carboxylic acid and 10- 65% by weight of a hydroxy component comprising 5-50% of ethylenically unsaturated monomer having at least one primary or secondary hydroxy group and 5-50% of an ethylenically unsaturated drying-oil-modified hydroxyterminated condensation resin, the amount of the unsaturated carboxylic acid monomer being within the range 1-10% and sufficient to disperse the copolymer by salt formation but insufficient to do so in the absence of said hydroxy component, the said percentages all being by weight based on the copolymer. Acid monomers specified are acrylic acid, methacrylic acid, crotonic acid, itaconic acid and monobutyl maleate. Examples of the first hydroxycontaining component are 2-hydroxy-ethyl acrylate or methacrylate, 2-hydroxy-propyl methacrylate, allyl alcohol and methallyl alcohol. The drying-oil modified resin is typically an unsaturated polyester formed by reacting components including a dicarboxylic acid and polyhydric alcohols comprising a major proportion of aliphatic compounds containing at least 3 OH groups; in examples the polyester is formed from linseed fatty acid, synthetic glycerine, isophthalic acid, azelaic acid, maleic anhydride, 1,1<SP>1</SP>-isopropylidene bis-(p-phenyleneoxy)-di-2-propanol and 2-ethoxyethanol. The balance of the copolymer is made up by one or more other monomer components, e.g. styrene, vinyl toluene, alkyl acrylates and methacrylates, acrylonitrile and alkyl vinyl ethers. The copolymer is obtained by polymerizing the corresponding monomers in a solvent (preferably water-miscible, using a catalyst such as benzoyl peroxide. The product is then treated with a base, e.g. ammonia, an amine or an alkali metal hydroxide or salt, and formulated into an aqueous dispersion. The dispersion may, if desired, include an aminoplast resin as a curing aid. Coatings obtained by electrodeposition can be cured by baking.

Abstract: 1493827 Semiconductor devices GENERAL ELECTRIC CO 28 Oct 1974 [14 Dec 1973] 46551/74 Heading H1K [Also in Division B1] A planar recrystallized region forming a PN junction with the surrounding semiconductor body is formed by thermomigrating an elongate melt comprising a solution of the semiconductor material and a dopant metal initially deposited on a (111), (110) or (100) surface of the body from the surface across a temperature gradient into the interior of the body, and then reversing the sense of the temperature gradient so that the melt migrates back along its former path to the surface leaving behind it a recrystallized "trail". To prevent mechanical strain developing the melt must not be allowed to solidify between the two thermomigration steps. Preferably a heating step follows the second thermomigration in order to round off by diffusion the lower end of the PN junction surrounding the region. Three alternative methods of reversing the temperature gradient are described. In the first the body is simply inverted in a fixed temperature gradient. In the second it is mounted on a holder which is rotable between zones of opposite temperature gradient. In the third the body remains stationary and the gradient is reversed by adjusting the currents in two resistance heaters located adjacent opposite faces of the body.

Title: Gyroscopic device
Inventor: WENDT HARRY CHRIST
IPC: G01C19/04
Filed: 1967-10-19
Abstract: 1,207,336. Gyroscopic apparatus. GENERAL ELECTRIC CO. Oct.19, 1967 [Dec.12, 1966; Dec.13, 1966], No.47736/67. Heading G1C. A gyroscopic device comprises a gyroscope having an inner gimbal 32, a rotor mounted on the inner gimbal for rotation about a spin axis A1-A2 and an outer gimbal 33 mounted on a support 36 for rotation about a major axis C1-C2, the condition of gimbal lock, i.e. alignment of the spin and major axes caused by manoeuvre of the support, being prevented by a stop device in conjunction with a rate sensor which determines the rate at which the gimbal lock position is approached. The stop device causes a 180 degree rotation of the outer gimbal and the spin axis is restored to its position prior to the manoeuvre of the support. It can be shown that for a given gimbal closure rate or rate of approach of the spin and major axis there is a fixed spin axis error on rotating the outer gimbal by 180 degrees. Two methods are available for correcting this error, namely: a) a fixed stop device is used and the gimbal closure rate is fed to apparatus which calculates the spin axis error for that gimbal closure rate. The apparatus energizes a torque so that the spin axis is precessed to nullify the error. b) the gimbal closure rate is fed to an adjustable stop means which determines and fixes the stop angle or minimum angle between the spin and major axes to ensure zero error in the spin axis orientation at the measured gimbal closure rate. Figure 6 illustrates method (a) in which the gimbal closure rate is measured by an electrical generator 51, the rotor of which is coupled by a shaft 52 to an inner gimbal tension 34. The apparatus 55 provides an output voltage which is amplified by an amplifier 45 and energizes torquing means 42. A fixed stop pin 54 strikes the outer gimbal to produce its 180 degree rotation. Several other methods of measuring the gimbal closure rate are also described and include a separate rate gyro, a slider and slidewire in conjunction with a differentiating circuit, an accelerometer in conjunction with an integrating circuit or the time for the 180 degree rotation of the outer gimbal may be determined since this time is inversely proportional to the square root of the gimbal closure rate. For method (b), several examples of adjustable stop means are described such as arrangements of pistons which automatically set the correct stop angle by adjusting the position of a stop cam in dependence on the gimbal closure rate. A solenoid, the coil of which is energized by the signal from a closure rate sensor so that the solenoid plunger is moved to the correct stop position, may also be used or an electric motor may control the position of a stop pin. Fig. 1 (not shown) illsutrates the stop device on a directional gyro to the outer gimbal of which a compass card is attached, a stationary index being mounted on one of the gyro supports to enable the compass to be read.
