Patent number: 9095983Abstract: A vacuum device for a material handling system includes a vacuum device body and a sealing element. The vacuum device body has a vacuum passageway in which a vacuum is generated in response to activation of a pressurized air supply that forces pressurized air through a venturi device. The sealing element moves to a sealing position to substantially seal the vacuum passageway when the air supply is activated, and is urged toward the sealing position via pressurized air that is diverted from an inlet of the vacuum device to the sealing element. The sealing element moves to substantially vent the vacuum passageway when the air supply is deactivated. The vacuum passageway may be in fluid communication with vacuum cup, which seals against the object when the sealing element is at the sealing position and the vacuum generating device generates at least a partial vacuum in the vacuum passageway.Type: GrantFiled: March 14, 2013Date of Patent: August 4, 2015Assignee: Delaware Capital Formation, Inc.Inventors: Maurice Perlman, Keith S.

Patent number: 9010811Abstract: A catch for securing a door to an object includes an engagement member connected to the door engaging a receiving member of a mount on the object. The door includes a first arm with an oblong hole for pivoting about a pin connected to the mount, and an engagement pin. Moving the door from a closed position causes the engagement pin to rotate with the door about the pivot pin. The door slides downward along the pivot pin as the pivot pin travels within the oblong opening, and the engagement pin makes contact with the receiving member, thereby retaining the door in an open position. Moving the door upward moves the pivot pin downward within the oblong opening disengaging the engagement pin from the receiving member, allowing the door to rotate to a closed position. A latch opposite the first arm retains the door in a closed position.Type: GrantFiled: October 18, 2013Date of Patent: April 21, 2015Assignee: Delaware Capital Formation, Inc.Inventors: Steven D.

First and second temperature sensors are spaced from one another and are coupled to the interior surface. The first sensor determines a temperature of the fluid. A temperature elevated by a heat source and determined by the second sensor is maintained above the temperature of the fluid. A second circuit determines a flow rate of the fluid based on adjustments to the heat source. Communication circuitry communicates the conductivity, the temperature, and the flow rate of the fluid to a controller.Type: GrantFiled: October 18, 2010Date of Patent: January 6, 2015Assignee: Delaware Capital Formation, Inc.Inventors: Stephen J.

Publication number: 20140278155Abstract: A cylindrical quartz crystal transducer that exhibits a low probability of twinning, and uses a combination of resonator signal inputs at the B-mode and C-mode frequencies to calculate resonator temperature. Crystallographic orientations are disclosed where combinations of B-mode and C-mode resonant frequencies exist that are sufficiently independent of pressure to enable accurate calculation of temperature under transient conditions. Such a transducer is usable at higher pressures and temperatures than conventional quartz pressure transducers. Furthermore, because the structure allows a choice of crystallographic orientation, other characteristics of the transducer, such as increased pressure sensitivity and activity dip-free operation, may be optimized by varying crystallographic orientation.Type: ApplicationFiled: March 15, 2013Publication date: September 18, 2014Applicant: DELAWARE CAPITAL FORMATION, INC.Inventors: Errol P.
