Patent number: 7485596Abstract: The present invention is for a process for making a heteropoly acid compound catalyst for oxidation of unsaturated aldehydes, such as methacrolein, to unsaturated carboxylic acids, such as methacrylic acid, said catalyst containing oxides of molybdenum, phosphorus, and M?, wherein M? is cesium, potassium, rubidium, or sodium, and bismuth. The process is a synthesis of the catalyst with specific process conditions for addition of the bismuth compound as an aqueous slurry without nitric acid. A catalyst precursor is formed by removing the water and drying the solid particles. The heteropoly acid compound catalyst is formed by calcination of the catalyst precursor.Type: GrantFiled: December 28, 2005Date of Patent: February 3, 2009Assignee: Saudi Basic Industries CorporationInventors: James W.

Patent number: 7229945Abstract: The present invention is for a process for making a catalyst for production of unsaturated aldehydes, such as methacrolein, by gas phase catalytic oxidation of olefins, such as isobutylene, said catalyst containing oxides of molybdenum, bismuth, iron, cesium, tungsten, cobalt, nickel, antimony, magnesium and zinc. The process is a two-part synthesis of the catalyst with the water insoluble components in one part and the water soluble components in the other part. The water insoluble components are co-precipitated to form an intermediate catalyst precursor of a precipitated support incorporating oxides of the metal components. The intermediate catalyst precursor is filtered and washed to remove nitrates. The intermediate catalyst precursor is slurried with the remaining water soluble components. A final catalyst precursor is formed by removing the water and incorporating the water soluble components. This two-part process reduces the amount of nitrates in the final catalyst precursor.Type: GrantFiled: December 19, 2003Date of Patent: June 12, 2007Assignee: Saudi Basic Industrics CorporationInventor: James W.

Patent number: 5414620Abstract: Synthetic friction force algorithms provide simulated static friction forces as well as dynamic friction forces. On either side of a hand-control element reference position a small static friction zone is established. As long as the hand-control element is within this static friction zone, the reference position remains constant and the control element drive motor generates a centering force proportional to the distance of the hand-control element from the reference position; a force urging the hand-control element toward the reference position. When the relative position of the hand-control element reaches or exceeds an edge of the static friction zone, it enters the dynamic friction zone. The motor applies a constant dynamic friction force, urging the hand-control element toward the reference position and the reference position is translated so that the edge of the static friction zone is translated to the current hand-control element position.Type: GrantFiled: August 9, 1993Date of Patent: May 9, 1995Assignee: Honeywell Inc.Inventor: James W. Kauffman

Patent number: 5347204Abstract: A control system for an active hand controller, for example, uses a control stick connected to and controlled by a motor. Electronics are provided to control the motor to eliminate oscillations due to motor torque and high gain due to breakout at the control stick when the control stick is at about its null position. Both hardware as well as software implementations can provide position dependent dampening to the control sticks such that when the control stick is located about a null position, a higher rate of dampening is provided than when the control stick is located outside the null position, when a lower rate of dampening is provided. The system provides a stable active hand controller control stick without degraded force and feel characteristics of the system.Type: GrantFiled: October 6, 1992Date of Patent: September 13, 1994Assignee: Honeywell Inc.Inventors: William W.
