[Class 2 (iii)] Alkyl nitrates are produced by reacting in alcohol with nitric acid of 35-68 per cent. strength under a pressure of 20-650 mm., the nitrate being removed by azeotropicdistillation, water (or in the case of ethyl or methyl nitrate, the ester) being returned from the distillate or otherwise to the reaction vessel to prevent accumulation of ester or water. The invention is applicable to the esterification of dihydric alcohols. Urea is preferably added during the process, and the water to be returned may be added in the form of solvent or diluent of the nitric acid, urea or alcohol. Examples 1-11 describe the esterification of n-butyl, 2-chlorethyl, mixed amyl, secondary amyl, iso-amyl, n-amyl, n-hexyl, secondary hexyl, 2-ethoxyethyl, cyclohexyl, and octyl nitrates, using the reagents in the liquid phase. The alcohol may be supplied in the liquid or vapour phase.

Granted: 1990-12-18
Abstract: A B S T R A C T          The invention provides a filter structure for use with a high voltage power pack for filtering particulates from a stream of air passing through the filter structure.  The structure includes a structural element for facing the stream of air and the back parallel and spaced from the front, the front and back defining a plurality of openings permitting a flow of air through the element.  A planar insulating substrate is positioned adjacent the front of the structural element and has openings aligned with the openings in the structural element and a plurality of conductors are carried by the substrate about the openings for charging by the power pack.  As a result, an electrostatic field is created across the openings orthogonally with respect to the flow of air between the conductors.  A non-conductive filter element is positioned in contact with the conductors and between the conductors and the back of the structural element.  The filter element defines tortuous paths for air flowing through the filter element whereby particulates in the air are ionized as they meet the electrostatic field and then impinge and are attached to the filter medium to clean the air.

Abstract: METHOD AND APPARATUS FOR POSITION ORIENTATION     OF A METAL HALIDE LAMP BASE ASSEMBLY                       ABSTRACT   A method and an apparatus for position orienting a base assembly of a metal halide lamp is describe for maintaining the curved arc tube in the upward position when the lamp is inserted in a socket.  Once the lamp has been fully assembled and sealed a locator structure is attached to the base shell in order to create a base assembly which will properly position the lamp when it in the socket,  The welding apparatus of the present invention resistance welds the locator structure onto the base shell once the locator structure has been aligned approximately 90 degrees counterclockwise from the lip of the curved portion of the arc tube when viewed from the dome end of the lamp.  The lamp resulting from the method and use of the apparatus will be more inexpensive and will not have the problems of a loose base or a cracked seal.
