Patent number: 7448566Abstract: The invention is a laboratory mill that allows small samples to be shaken, mixed, ground, homogenized or comminuted effectively within a small vial. The design is similar to a planetary mill but unlike those devices, neither axis of rotation is centered on the axis of the processing vessel. The design allows many vials to be processed at one time and even when the diameter of the vial is quite small, maintains the processing performance. The performance of the device when used as a comminuter is demonstrated showing that the device can comminute organic solids down to a median particle size of 1 micrometer with a narrow size distribution. Because the processing takes place within a vial, the mill does not require cleaning between samples which allows the application of the device in automated or high throughput systems.Type: GrantFiled: February 10, 2006Date of Patent: November 11, 2008Inventor: Stephen Robert Bysouth

Patent number: 6942169Abstract: A method and device for performing lysing on a cell-containing fluid, in which the fluid flows through a vibrating micromachined tube to physically rupture the cell walls (mechanical lysis), and/or to mix, agitate or homogenize the fluid during chemical lysis, and/or to mix, agitate or homogenize the lysate for analysis or other processing after lysing. The tube includes a freestanding portion spaced apart from a surface of a substrate on which the tube is formed. The device further includes means for vibrating the freestanding portion of the tube at a level sufficient to rupture the walls of cells in a fluid flowing through the freestanding portion (for mechanical lysing) or to mix the fluid and a chemical lysing additive within the freestanding portion (for chemical lysing).Type: GrantFiled: March 7, 2002Date of Patent: September 13, 2005Assignee: Integrated Sensing SystemsInventor: Douglas Ray Sparks

Publication number: 20040216568Abstract: A method of destroying signals stored on a compact disk includes the step of destroying a Start Lead In (SLD) area on a compact disk to ruin lead-in signals recorded on the SLD, such that all other data stored on the compact disk cannot be read. Undesirable disclosure of the data stored on the compact disk is effectively prevented when the compact disk is discarded after the SLD is destroyed.Type: ApplicationFiled: June 11, 2003Publication date: November 4, 2004Inventor: Jin-Sheng Weng

Publication number: 20040182960Abstract: A dual nozzle hydro-demolition system is mounted on a robot vehicle having a tower, with the robot vehicle and tower permitting the device to be positioned in any desired location on a vertical wall surface. The robot vehicle includes a plurality of tires and a motive power system allowing it to be moved to a desired location. Bearing pads are mounted on jacks allowing the tires of the robot vehicle to be elevated slightly off the ground to preclude undesired movements. A carriage is slidably mounted on a beam and carries dual nozzles, each of which is connected to a supply of high pressure water via a heavy duty hose. The nozzles are rotated using a hydraulic motor. A coupling is provided within the flow circuit from the source of water to the nozzle allowing a conduit adjacent the nozzle to rotate with respect to a conduit receiving water from the source thereof, so that each nozzle can be rotated without any water leakage.Type: ApplicationFiled: March 4, 2003Publication date: September 23, 2004Applicant: Ash Equipment Company, Inc.

Patent number: 6786440Abstract: A container for blender includes a cup and a stainless steel hollow cylindrical member. The cylindrical member has an L-shaped upper rim and an annular bottom having an L-shaped inner edge. The cylindrical member is integrally fitted in a lower part of the cup when the latter is injection-molded with the L-shaped upper rim and the L-shaped inner edge of the annular bottom imbedded in peripheral wall and bottom wall of the cup, respectively. The cylindrical member protects the cup against direct contacting with and colliding by rigid materials being crushed in the cup, and accordingly eliminates tiny chips of the cup that would otherwise be produced due to such colliding.Type: GrantFiled: June 18, 2002Date of Patent: September 7, 2004Inventors: Kuo-I Ling, Rong-Yuan Tseng

Patent number: 6739531Abstract: An apparatus for disrupting cells or viruses comprises a container having a chamber for holding the cells or viruses. The chamber is defined by at least one wall having an external surface for contacting a transducer device. The transducer device has a vibrating surface for contacting the wall and for vibrating at an operating frequency and amplitude sufficient to generate pressure waves or pressure pulses in the chamber. The transducer device is coupled to the wall with a preload force sufficient to create a stress within the wall. The natural frequency of the wall, when the wall is stressed by the preload force, is equal to the operating frequency of the transducer device or differs from the operating frequency by less than 50% of the operating frequency.Type: GrantFiled: October 4, 2001Date of Patent: May 25, 2004Assignee: CepheidInventor: Michael T. Taylor

Patent number: 6722594Abstract: A pulverizer is disclosed which comprises a fan which sucks air through a pipe. A hopper receives material which is to be pulverized, the hopper having an open lower end which communicates with the pipe. Between the hopper and the fan there is a venturi. Air flows through the venturi at a speed of Mach 1 or above. Pieces of frangible material dropped into the hopper are sucked to the venturi where they are blown apart and reduced to powder.Type: GrantFiled: February 26, 2001Date of Patent: April 20, 2004Inventor: William Graham

Patent number: 6712298Abstract: The present invention relates to a method and a device for crushing glass bodies, in which the glass body 18 is arranged in a microwave field 4, so that the said glass body 18 is crushed on account of the resulting thermal stresses. In addition, a local plasma 20, which results in further thermal stresses, is produced on the surface of the glass body 18. Since the glass body 18 to be crushed does not come into contact with crushing means, for example rollers or the like, the pieces of broken glass 22 cannot be contaminated by abrasion particles of the crushing means. The plasma 20 permits a rapid and economic crushing of the glass bodies.Type: GrantFiled: February 27, 2001Date of Patent: March 30, 2004Assignee: Schott GlasInventors: Uwe Kohlberg, Hildegard Römer, Michael Kohl, Thorsten Gerdes
