Patent number: 7134620Abstract: An electric ice planer includes a bottom base, a frame base, a transmitting mechanism, a stationary cap, a lift cap, a plane base, a fit cylinder, and an ice container. The transmitting mechanism rotates the ice container, so small ice blocks placed in the ice container may be guided to move on a helical guide member in the ice container to a plan of the plane base and then planed into small bits of ice and then drops down into a container on a receptive surface of the bottom base below the plane base for use. So the electric ice planer saves time and labor, not wasting ice blocks and simple to assemble and disassemble for convenience of washing and cleaning.Type: GrantFiled: December 19, 2005Date of Patent: November 14, 2006Inventor: Ming-Tsung Lee

Patent number: 7118056Abstract: A chemical waste collection and disposal system for fluorescent lamps that allows for the safe collection and disposal of crushed or broken fluorescent lamps, while recovering substantially 100% of the hazardous mercury vapors contained within the lamps. A fluorescent lamp is inserted within a drum and broken into fragments by one or more blades, with the fragment falling to the bottom of the drum. The mercury vapors that are emitted from the broken fluorescent lamps are forced out of the drum by negative positive pressure created by a vacuum/filter assembly. Once through the filter assembly, which includes a HEPA filter and activated carbon filter, the gases are permitted to escape into the environment virtually 100% free of mercury toxins.Type: GrantFiled: March 12, 2004Date of Patent: October 10, 2006Assignee: Killgerm Group LimitedInventor: Edward J.

Publication number: 20030058121Abstract: Woodworking machines including cutting tools and motors adapted to drive the cutting tools are disclosed. The machines also include a detection system adapted to detect a dangerous condition between the cutting tool and a person, and a reaction system adapted to perform a specified action upon detection of the dangerous condition. The machines further include a control system adapted to test the operability of at least a portion of the detection system and/or the reaction system. The control system is adapted to disable the motor if the tested portion is inoperable. The control system also includes a test mode to test whether the detection system is working, to test whether various materials would be detected by the detection system, and/or to test whether various materials would trigger the reaction system.Type: ApplicationFiled: September 13, 2002Publication date: March 27, 2003Inventors: Stephen F. Gass, David A. Fanning

Publication number: 20030052205Abstract: An angle-based method and device to protect a grinding mill used for grinding material therein by rotating the drum so that the material adheres to the drum inner surface and rises therewith over a cascading angle from a gravity-balanced condition prior to detach by gravity from the inner surface and tumble into a cascading flow. The method is used for protecting the grinding mill from damages potentially resulting from the material agglomerating into a generally solidified lumped volume that could adhere to the inner surface and rotate with the latter more than the cascading angle to a fall angle wherein the lumped volume may detach from the drum inner surface and impact an impact position within the drum.Type: ApplicationFiled: September 17, 2002Publication date: March 20, 2003Inventor: Ehrenfried Albert Tirschler

Patent number: 6513967Abstract: The invention is directed to a safety device for a jug blender that has a blender jug (10) adapted for seating engagement with a base (7) equipped with a drive motor. The safety device includes two vertically movable actuating pins (1) arranged in spaced relation to each other and projecting upwardly through the wall of the base (7), and the blender jug (10) has actuating points (11) cooperating therewith which, with the blender jug (10) properly assembled, urge the two actuating pins (1) simultaneously and evenly horizontally in downward direction in order to thus close the circuit supplying the drive motor. Any improper handling or activation of the motor with the blender jug (10) not properly positioned is avoided by connecting actuating members with the actuating pins (1) in the base (7) in such manner that a safety switch does not close unless the pins (1) are urged down evenly and at the same time horizontally.Type: GrantFiled: September 17, 2001Date of Patent: February 4, 2003Assignee: Braun GmbHInventors: Josep-Maria Masip, Jose Luis Roman, Robert Rafols, Mariano Peñaranda

Patent number: 6510784Abstract: A safety device for a food processor having a bowl closed by a cover and fed through a chute for introducing products into the working bowl, has a control switch responsive to the position of a pusher guide carrying a pusher. The pusher is slidably mounted for translation in the pusher-guide. The pusher-guide is pivotally mounted to cover over the open end of the chute, and a set of rods connect the pusher-guide to the switch operating safety rod extending along the bowl. The device prevents access of the user's hand to the cutting area, even for a large chute, by blocking the chute when the motor is enabled.Type: GrantFiled: February 26, 2002Date of Patent: January 28, 2003Assignee: Robot CoupeInventors: Loic Fevre, André Gateaud, Pierre Perrin

Patent number: 6474578Abstract: A safety push-button keypad for a food processor has a base with an electric motor and its command circuit operated by a push-button key pad. A removable container is mounted on the base and can be closed with a cover. The cover has a cam that comes to rest, when the cover is locked onto the container, on the end of a stem running into a housing extending along an axis relative to the container, which can be cylindrical. Above the stem and in its extension extends a piston on which is fixed a microswitch mounted running into the base, a related push button corresponding with a lever coming to bear, when the piston is down, on the contact of the microswitch.Type: GrantFiled: November 22, 2000Date of Patent: November 5, 2002Assignee: Robot CoupeInventors: Patrick Gonneaud, Jean-Pierre Lazzer

Patent number: 6450426Abstract: An ice planer includes a base, a fix frame, a cylinder, a body, a safety hook, a transmit device and a push cap. When the body is fitted with the cylinder, the safety hook rests against the inner wall of the cylinder and its upper end separate from the touch switch, and a planing plate under the body presses down ice blocks in the cylinder and pushes up the transmit shaft of the transmit device, with the touch switch moved up. Then the push cap is pressed to touch the touch switch to turn on the transmit device to operate the ice planer. Thus, the ice planer has three separate safety measures to let its use very safe, and in addition, the transmit device is contained in the body, not to get wet to increase its service life, with the components easily assembled and disassembled.Type: GrantFiled: January 18, 2001Date of Patent: September 17, 2002Inventor: Ming-Tsung Lee
