Publication number: 20140243543Abstract: New hexa-coordinate iron (II) complexes comprising compounds of formula (I) are described. These compounds comprise a tetradentate ligand with donor atoms comprising nitrogen and phosphorus. These complexes are shown for the first time to be useful catalysts for the hydrogenation of ketones, aldehydes, or imines to produce alcohols or amines, and the asymmetric hydrogenation of prochiral ketones or imines to produce non-racemic alcohols or amines. The source of the hydrogen can be hydrogen gas or a hydrogen-donating molecule such as isopropanol or hydrogen-donating mixture such as formic acid and an amine depending on the structure of the catalyst. In certain embodiments, the axial ligands on the catalyst comprise organonitrile ligands, carbonyl ligands, isonitrile ligands, or combinations thereof.

Patent number: 6131463Abstract: A system for optimizing the flow of air through a fume hood by dynamically controlling the air flow to provide a stable vortex in the vortex chamber of the hood, the optimum condition for minimizing backflow of fume-laden air through the hood doorway. A highly-sensitive pressure sensor disposed at a critical location in the vortex chamber sidewall senses minute variations in vortex pressure indicative of turbulence and sends signals via a transducer to an analog controller which uses proportional integral and adaptive gain algorithms to formulate output signals to an actuator which adjusts dampers in the hood to change the airflow into the vortex. The system operates in feedback mode and seeks a minimum in the amplitude of the sidewall pressure variations, indicating that turbulence has been eliminated and that a stable vortex exists. The pressure sensor signals can also be directed to an alarm to signal an off-standard and potentially dangerous condition.Type: GrantFiled: August 26, 1997Date of Patent: October 17, 2000Assignee: Flow Safe, Inc.Inventor: Robert H. Morris

Patent number: 5924920Abstract: The flow of air through a fume hood is optimized by producing a bi-stable vortex within the vortex chamber of the fume hood regardless of sash movement. A bi-stable fume hood optimizes capture face velocity to minimize backflow of fume laden air through the hood sash opening. This bi-stable vortex fume hood reduces the energy consumption up to sixty percent versus the present day mono-stable vortex fume hoods. The bi-stable vortex fume hood utilizes a vortex pressure control system to reposition top, center, and bottom slot openings of a baffle in the hood. This baffle moves the bi-stable vortex away from the fact when the sash is fully opened and creates a clearing action near the work surface as the sash is closed. The fume hood's airfoil is placed inside the fume hood chamber and the airfoil has multiple entry pattern, one of which turns the vortex up and away from the open sash window. The other creates flow which washes the work surface of the hood.Type: GrantFiled: January 15, 1998Date of Patent: July 20, 1999Assignees: Flow Safe, Inc., Lab-Crafters, Inc.Inventors: Robert A. DeLuca, Robert H. Morris

Patent number: 4741257Abstract: A control system is provided for providing a constant flow of air through a chamber, such as a fume hood, by measuring the pressure of the air outside of the hood and comparing it with the pressure of the air within the hood and adjusting the flow of air to achieve a constant pressure difference. The system is particularly applicable to fume hoods which have a sash which can be opened or closed or left in intermediate position; the present system will provide a constant air flow through the hood regardless of the sash position.Type: GrantFiled: January 9, 1985Date of Patent: May 3, 1988Assignee: Air Monitor CorporationInventors: Merlon E.

Patent number: 4134306Abstract: A rotary actuator for converting reciprocating motion to rotary motion including a housing having spaced-apart end plates connected by guide rods. A bellows is provided having opposite sides one of which is connected to one of the end plates, the bellows being adapted to be connected to a source of fluid under pressure so that the bellows expands from a collapsed to an expanded position. A guide plate is provided movably mounted on the guide rods with the other bellows side being connected thereto. A rack and pinion assembly is provided mounted on the other end plate, the rack being connected to the guide plate so that expansion and contraction of the bellows causes linear movement of the rack thereby imparting rotary movement to the pinion. A spring acts between the guide plate and the other end plate thus resisting expansion of the bellows and returning it to the collapsed position upon the release of fluid pressure.Type: GrantFiled: September 20, 1976Date of Patent: January 16, 1979Assignees: Phd, Inc., Hughes Industrial Products, Inc.Inventors: Gunnar Grotness, Charles S. Smith, Robert H. Morris, Peter W. Boyer
