Patent number: 7064639Abstract: A magnetic latching switch. The switch includes a pair of switch terminals, a switch actuator, an electromagnet and a biasing member. The switch actuator is manually moveable from a first position where the switch terminals are in a first state to a second position where the switch terminals are in a second state. The electromagnet selectively applies a magnetic field. Applying the magnetic field with the electromagnet when the switch actuator is in the second position maintains the switch actuator in the second position. The biasing member is coupled to the switch actuator such that the biasing member automatically returns the switch actuator from the second position to the first position when the magnetic field is removed.Type: GrantFiled: July 30, 2004Date of Patent: June 20, 2006Assignee: Delta Systems, Inc.Inventors: Arthur James Harvey, Michael Eric Liedtke, Ted Wetzel

Patent number: 7000325Abstract: A power operated knife comprises a blade supporting structure supporting an annular blade for rotation about a central axis. The blade and blade supporting structure are engagable along bearing contact locations that are spaced apart in a direction parallel to the axis so that the blade is stabilized both radially and axially as the knife operates. The blade supporting structure comprises a split blade housing member that is radially expandible and contractible to receive the blade. The split blade housing member and blade engage along relatively short lines of bearing contact that serve to minimize friction and blade heating when the knife operates. The bearing locations are spaced apart both circumferentially around the blade perimeter and in the direction of the axis so that the blade position is stabilized during operation of the knife.Type: GrantFiled: July 30, 2004Date of Patent: February 21, 2006Assignee: Bettcher Industries, Inc.Inventor: Jeffrey A.
