Title: Hydroformylation process.
Inventor: COOPER JAMES LEE
IPC: C07C45/85
Filed: 1982-04-19
Abstract: A hydroformylation process employing a rhodium-containing catalyst for the preparation of aldehydes, principally those having relatively high proportions of branched isomer. These aldehydes are prepared by hydroformylating an olefin in liquid solvent with a mixture of hydrogen and carbon monoxide in the presence of the catalyst to form a liquid composition. At least a portion of this liquid composition is contacted with an oxygen containing gas prior to recovery of gaseous aldehyde by distillation and then it is distilled at a temperature of 120<o> or less. The liquid composition obtained from the distillation can be recycled to the hydroformylation reaction.

IPC: G05B19/19
Filed: 1987-12-18
Abstract: Le système asservi décrit sert à positionner un élément (58) monté sur un ressort (57). Le ressort (57) produit une force s'opposant au mouvement de l'élément (58) par rapport à une position initiale. Un actuateur de positionnement, par exemple un moteur (28), imprime une force en réponse à un signal de demande de positionnement (11) pour déplacer l'élément (58) dans une position désirée. Une partie du signal de réaction de positionnement (13) est appliquée depuis un détecteur de position (48) au moteur (28) comme signal de réaction positif (51) pour compenser la force du ressort. Une erreur de position permanente (E) du système asservi est ainsi réduite essentiellement à zéro. Un circuit (65) et un procédé servant à étalonner le signal de réaction positif (51) sont également décrits.

Title: Electromagnetic interference testing apparatus.
Inventor: OSBURN JOHN D
IPC: G01R29/08
Filed: 1993-03-01
Abstract: A transverse electromagnetic (TEM) cell (10) for measuring EM emissions. The TEM cell longitudinal axis is positioned at a fixed angle relative to the horizontal. This fixed angle results in the alignment of the orthoaxis of the TEM cell with the gravity vector. A rotatable platform (19) for supporting an electronic device (18) is positioned inside the TEM cell (10). The platform (19) is mounted horizontally, and its axis of rotation is vertical (i.e. parallel to the gravity vector). Further, the rotation axis of the rotatable platform intersects the test volume of the TEM cell. Three mutually orthogonal components of EM emissions are measured successively by placing a device (18) on the platform (19) and rotating the device (18) through two 120 degree rotations, thereby measuring three positions. Thus, it is not necessary to tilt the device (18) from a normal, horizontal operating position in order to fully test its EM emissions.

Title: Process for producing difluoromethane
Inventor: TSUDA TAKEHIDE
IPC: C07C17/20
Filed: 1995-06-07
Abstract: Difluoromethane is prepared by reacting dichloromethane and hydrogen fluoride in a liquid phase in the presence of a fluorination catalyst under reaction conditions in which the reaction pressure is between 1 and 10 kg/cm<2>ab., and the reaction temperature is between 50 and 150 DEG C, provided that the selected reaction temperature is higher than a temperature at which hydrogen fluoride is not liquefied under the selected reaction pressure. Under the above conditions, the conversions of dichloromethane and HF are very high, and amounts of by-products other than R30 are very low, typically less than 0.1 % per difluoromethane, when the unreacted materials are recycled. A material of a reactor is hardly corroded by the reaction using an antimony chlorofluoride and HF which are highly corrosive, as long as the above conditions are maintained.

Title: Glass coating method and glass coated thereby
Inventor: SOUBEYRAND MICHEL J
IPC: C23C16/40
Filed: 1995-10-13
Abstract: A method of pyrolytically forming a silica-containing coating on a glass substrate at an elevated temperature. Silane, oxygen, a radical scavenger gas and a carrier gas are combined as a precursor mixture, and the precursor is directed toward and along the surface of the heated glass substrate. The presence of the radical scavenger allows the silane, which is pyrophoric, to be premixed with the oxygen without undergoing ignition and premature reaction at the operating temperatures. The radical scavenger further provides control of and permits optimization of the kinetics of the chemical vapor deposition (CVD) reaction on the glass. A preferred combination of precursor materials includes monosilane and oxygen, with ethylene as the radical scavenger, and including nitrogen as a carrier gas.
Patent EP-0852073-A4 (EP)
Title: De-icing of satellite antenna with cover
Inventor: WALTON WILLIAM B JR
IPC: H01Q1/02
Filed: 1996-09-19
Abstract: A system for preventing the interruption of satellite communications between an earth antenna and a satellite during inclement weather. The system is comprised of a cover that is adapted to be positioned on the opening of the satellite cover so as to reduce the likelihood of liquid water accumulating on the front reflecting surface of the antenna. The cover and the front reflecting surface further define a space and an air circulation system circulates air in the space. The circulating air increases the air pressure in the space relative to the surrounding atmosphere and pressurized air then travels through the cover and blows water accumulating on the outer surface of the cover off of the outer surface to further reduce the likelihood that accumulations of water on the outer surface of the cover will result in interruptions to satellite communications with the earth based satellite antenna.
