Patent number: 8607812Abstract: A butterfly valve for handling materials where the temperature of the materials flowing through the butterfly valve can exceed the breakdown temperature of the sealing member with the butterfly valve inhibiting contact of hot transportable materials with the sealing member to isolate the hot transportable materials from the sealing member. Cooling conduits maintain at least portions of the valve that contacts the sealing member at a temperature below the breakdown temperature of the sealing member to prevent seal failure.Type: GrantFiled: May 15, 2012Date of Patent: December 17, 2013Assignee: Dynamil Air Inc.Inventor: James R.

Patent number: 8544654Abstract: A magnetic separator comprising a vibratory conveyor for vibratorily flowing non-ferrous articles and articles containing ferrous material within the magnetic field of a transverse extending magnet to magnetically capture the articles containing the ferrous material while allowing the non-ferrous articles to flow therepast. The magnet is periodically retractable to remove ferrous articles magnetically adhered thereto. The use of a set of transverse extending magnets enables a continuous on-the-go separation of articles containing ferrous material from non-ferrous articles without having to shut down the vibratory conveyor.Type: GrantFiled: May 31, 2011Date of Patent: October 1, 2013Inventors: Leonard Williams, James R.

Patent number: 7438090Abstract: A flow valve having sealing member having a first condition for engaging a housing to prevent back flow and a platform for obstructing a flow passage through the flow valve with the platform supporting the sealing member in an out-of-the-way condition to allow fluid to flow through the flow valve.Type: GrantFiled: January 6, 2005Date of Patent: October 21, 2008Inventor: James R.

Patent number: 7267475Abstract: A mixing apparatus and method wherein the mixing apparatus includes a hopper having a port piston for periodically retracting to open a fluid port to allow a slug of gas to be quickly injected into the bottom of a hopper, which produces a mixing and blending of the materials in the hopper as the slug of gas flows upward through the materials in the hopper. The port piston periodically closes to seal the fluid port without allowing the material in the hopper to backflow, which would prevent between the port piston and a hopper sealing member from being brought into sealing engagement.Type: GrantFiled: May 21, 2003Date of Patent: September 11, 2007Assignee: Dynamic Air Inc.Inventor: James R. Steele

Patent number: 6305412Abstract: A pressure relief valve that includes a sealing arrangement with a cantilevered seal that prevents fluid from escaping from a system if the differential pressure is only slightly positive yet permits fluid to be released from the system if the internal system pressure exceeds a predetermined pressure differential. In a further embodiment, the pressure relief valve includes a further scaling arrangement with a further cantilevered seal, which is normally closed, but if the internal system pressure should decrease below the external pressure a predetermined amount the second scaling arrangement opens to allow fluid into the system to thereby equalize the pressure and thereby prevent collapse of the system.Type: GrantFiled: March 27, 2000Date of Patent: October 23, 2001Assignee: Dynamic Air Inc.Inventor: James R. Steele

Patent number: 6074136Abstract: A multi-port pneumatic switch having a drive system including a motor and a gear reduction box that rotates a rotatable plate which carries a rotateable conduit having an offset end and a non-offset end with the offset end postionable into precise flow alignment with any of a plurality of outlet conduits through the coaction of a photoelectric alignment system that detects a light beam reflection from a reflector on the rotatable plate to immediately shut the power to the drive system and thereby stop further forward rotation of the rotatable plate. With the cessation of power to the drive system a pivotal arm swings into engagement with a radial stop on the rotatable plate to lock the rotatable plate from further forward rotation while the drive system which is powered through a gear reduction drive functions as brake to prevent back rotation of the rotatable plate once the power is shut off to the motor.Type: GrantFiled: January 27, 1998Date of Patent: June 13, 2000Assignee: Dynamic Air Inc.Inventor: James R. Steele

Patent number: 6030152Abstract: A pneumatic switch having a wiper seal to inhibit material from escaping from a pneumatic conveying line during a switching process and to maintain the pneumatic conveying line in a closed condition to prevent contamination of the contents of the pneumatic conveying line and an inflatable seal to seal around a pneumatic conveying line with the pneumatic switch including a movable housing that is moveable with respect to a second pneumatic conveying line. The movable housing bearing is carried by a movable plate that allows one to position or reposition the pneumatic conveying line with respect to another conveying line to thereby divert material from one conveying line to another conveying line while an inflatable seal allows one to seal and reseal around the pneumatic conveying line.Type: GrantFiled: January 8, 1998Date of Patent: February 29, 2000Assignee: Dynamic Air, Inc.Inventor: James R. Steele
