Title: Process for the production of thixotropic oils
IPC: C09D5/04
Filed: 1959-10-21
Abstract: The thixotropic oils produced by the process of the parent Specification are replaced by oils obtained by interesterifying 1 molecular proportion of a drying or non-drying oil, for example varnish linseed oil, with 0,5-2,5 molecular proportions of a polyhydric alcohol, for example ethylene glycol, generally in the presence of a catalyst such as lithium naphthenate, and then reacting the product with a "masked" organic diisocyanate obtained by the reaction of a diisocyanate with a phenol or a compound containing a reactive methylene group such as acetoacetic ester, or malonic acid or its esters, the "masked" diisocyanate being present in an amount equivalent to the free hydroxyl groups present, and the polyhydric alcohol, the diisocyanate or both having a symmetrical molecular structure. The "masking" compound used is preferably one, such as phenol, that is driven off at the reaction temperature leaving unmasked diisocyanate; suitable "masked" diisocyanates are obtained by reacting 1 mole of 1 : 5-dimethyl-2 : 4-di-(o -isocyanatomethyl) benzene or hexane-1 : 6-diisocyanate with 2 moles of phenol.  The thixotropic oils obtained may be used in combination with alkyd resins, unsaturated polyesters, and modified natural and phenolic resins.ALSO:Thixotropic oils are obtained by interesterifying 1 molecular proportion of a drying or non-drying oil, for example varnish linseed oil, with 0.5-2.5 molecular proportions of a polyhydric alcohol, for example ethylene glycol, generally in the presence of a catalyst such as lithium naphthenate, and then reacting the product with a "masked" organic diisocyanate obtained by the reaction of a diisocyanate with a phenol or a compound containing a reactive methylene group such as acetoacetic ester, or malonic acid or its esters, the "masked" diisocyanate being present in an amount equivalent to the free hydroxyl groups present, and the polyhydric alcohol, the diisocyanate, or both having a symmetrical molecular structure.

Abstract: 1,173,673. Light modulators. WESTERN ELECTRIC CO. Inc. 10 Aug., 1967 [29 Aug., 1966], No. 36779/67. Heading H4F. [Also in Division H1] To eliminate the baseband frequency resonance phenomenon in electro-optic materials which due to their piezoelectric nature are subject to physical resonances when subjected to modulating electric fields at frequencies between 10 and 100 KHz, the electro-optic element is mechanically clamped to increase the stiffness of the electro-optic modulating element and thus raise the physical resonance frequencies into the 1-10 MHz range, and the resulting high frequency resonances are damped out by immersing the electro-optic element in a viscous fluid. The dielectric constant of the viscous fluid is arranged to equal the dielectric constant of the element so as to provide reflectionless transition between the electrooptic material and the surrounding fluid. In the embodiment described, ADP or KDP electro-optic element 39, Fig. 2, is positioned in the cavity formed by half cylindrical members 31, 32 spaced apart by spacers 33, 34. The cavity is filled with silicone oil (element comprising KDP) and thin direct clamping strips 40, 41 of pliant material are positioned as shown on the extended side portions of the element. These strips preferably comprise lead and the sum of the thickness of element 39 and strips 40, 41 is selected to be 0.5 mils greater than the thickness of spacers 33, 34, so that when screws 35, 36 are tightened the lead is " hard clamped," i.e. the yield pressure of 800 Ib./sq. inch of the lead strips 40, 41 is exceeded. The modulating field is applied to the electro-optic element by means of gold electrodes 42, 43 extending the length of the element. The ends of the cavity are closed by a reflector (45, Fig. 3, not shown) and a transparent plate (46) and in operation the modulator is disposed as one extremity of an optical cavity with an additional reflector positioned opposite reflector (45) and on the axis of propagation of energy from a laser which is disposed between the reflectors on the cavity axis, Fig. 1 (not shown). The application of an electric field at baseband frequencies across the electro-optic material causes a variation in the refractive index of the material and produces frequency modulation of the laser beam passing therethrough.
