Abstract: The disclosure relates to a process for making linear, substantially water-insoluble ammonium polyphosphates of the general formula (NH4PO3)10-1000 by heating and continuously mixing phosphorus pentoxide and ammonium orthophosphate in the presence of ammonia and tempering the resulting reaction product over a period of several hours at 200 DEG  to 400 DEG  C. in the presence of ammonia. To this end, the phosphorus pentoxide and ammonium orthophosphate are subjected at 50 DEG  to 150 DEG  C. to the following successive operations which provide (a) for them to be reacted with ammonia over a period of 5 to 15 minutes under an overpressure of 1-2 millibars, (b) for them to be mixed under nitrogen for 10 to 60 minutes at atmospheric pressure while arresting the supply of ammonia, (c) for them to be reacted with ammonia over a period of 1 to 3 hours under a pressure 1 to 5 millibars lower than atmospheric pressure, and the reaction product is tempered, the ammonia being used in an overall stoichiometric excess of at most 20 mol %. The disclosure is also concerned with the ammonium polyphosphates so obtainable which are characterized by the following typical data which provide: (a) for the solubility of a 10 weight % suspension in pure water at 25 DEG C. to be less than 0.8 g per 100 g suspension; (b) for the viscosity of a 10 weight % suspension in pure water at 25 DEG  C. to be at most 100 mPa.s; (c) for the viscosity of a 30 weight % suspension in a polyesterpolyol at 25 DEG  C. to be at most 50 Pa.s.

Abstract: Ether is produced from isoolefins having four to five carbon atoms per molecule, a monohydroxy alcohol having from one to five carbon atoms per molecule and a recycle stream comprising unreacted alcohol and water by passing the stream passed through a etherification zone to produce the desired effluent stream, separating the effluent stream into an ether product and an aqueous product containing unreacted alcohol and recycling a portion of the aqueous product to the etherification zone. Distillation is employed to separate the effluent from the etherification zone into a bottoms product stream, comprising the product ether, a distillate product comprising other hydrocarbons contained in the feed and the above-mentioned aqueous recycle stream. When producing ethyl-tertiary-butyl ether (ETBE), azeotropic grade ethanol, i.e., about 5 vol.% water, is preferably utilized. The utilization of the alcohol/water recycle stream can obviate the need for additional alcohol recovery from the distillate product.

Abstract: Système amélioré de mise en oeuvre d'un procédé d'alkylation et méthode de manipulation d'un catalyseur liquide lors de ce processus d'alkylation. Cette amélioration concerne une méthode et un appareil grâce auxquels un catalyseur d'alkylation liquide présent dans l'équipement d'alkylation peut être entreposé de façon sécuritaire, en demeurant isolé du milieu extérieur. L'amélioration de cet appareil permettra également de faire appel à une méthode améliorée de régulation de la circulation du catalyseur d'alkylation liquide en fournissant un moyen d'arrêter rapidement la circulation de ce catalyseur d'alkylation. Cette amélioration repose notamment sur l'utilisation d'un déflecteur placé dans un récipient, au fond duquel il est fixé et qui se prolonge vers le haut. Ce déflecteur est conçu pour permettre la circulation du liquide entre l'intérieur du récipient et l'intérieur du déflecteur et pour permettre une évacuation dans un espace de vapeur à partir de la partie supérieure de ce déflecteur. Ce déflecteur comporte une colonne montante permettant la circulation du liquide de l'intérieur du déflecteur vers un espace situé à l'extérieur.

Title: Gas spring actuator
Inventor: SNYDER DAVID E
IPC: F16K31/122
Filed: 1991-11-12
Granted: 2001-12-18
Abstract: A gas spring actuator which, when attached to a valve, will return the valve to its initial position after the valve has been moved to a second position by application of a pressurized fluid that opposes the gas spring. The gas spring is charged to a predetermined gas pressure. A hydraulic fluid is applied in an opposing manner to drive the piston in one direction to operate the valve and simultaneously pressurize the gas in the gas spring. Upon removal of the hydraulic pressure, the pressurized gas returns the piston, and the valve, to its initial position.

Title: Shifted pole single phase variable reluctance motor
Inventor: HORST GARY E
IPC: H02K29/08
Filed: 1992-03-25
Granted: 1997-11-18
Abstract: A hybrid single-phase variable reluctance motor (31) comprises a stator (33) having a plurality of inwardly salient teeth (41A-41D)  terminating at a central bore (37).  The teeth are arranged in generally diametrically opposed pairs of teeth and are generally evenly spaced around the bore.  A phase winding (43) is operatively associated with one pair of the stator teeth.  The winding, when energized, causes a temporary magnetization of the stator teeth.  A rotor (35) is disposed for rotation in the bore and has outwardly salient teeth (45A, 45B) generally diametrically opposed to each other.  A permanent magnet (53) is disposed adjacent the bore at the end of one tooth (41D) of a second pair (41C, 41D) of stator teeth.  One tooth (41D) of the second pair of stator teeth is offset with respect to a longitudinal axis (A1) of the second pair of teeth.  This offset acts to eliminate a stable detent position in which the rotor could otherwise "park" itself when it stops running.  Parking in such a position makes it difficult to restart the motor.

Title: Confirmation of hydrogen damage in boiler tubes by refracted shear waves
Inventor: LATIMER PAUL J
IPC: G01N29/04
Filed: 1992-06-03
Granted: 1996-08-06
Abstract: ABSTRACT OF THE DISCLOSURE           A method and apparatus for distinguishing between hydrogen damage in the wall of a boiler tube, and surface damage on the inside surface of the tube, comprises a pair of transducers which are spaced on the outer surface of the tube and which apply a refracted shear ultrasonic wave through a chord of the tube with a beam angle that is calculated from the outside radius and wall thickness of the tube.  The transducers are first applied to an undamaged tube and an instrument connected to the transducers is adjusted to 80% of full screen height.  The same transducers are then applied to a suspected boiler tube.  Any attenuation of the initially high amplitude below 12 dB indicates hydrogen damage as opposed to inner surface damage which has been found to produce a far lower attenuation.
