Abstract: An instrument for obtaining tissue samples from a site deep within the body. The instrument has an elongated proximal portion that is constructed to follow a long, torturous path to the site and has a distal end constructed to sever and remove a tissue sample from the body, including tissue specimens, polyps or the like. The instrument is constructed to take multiple biopsy samples without being withdrawn from the body. The instrument includes a tissue sample retractor. The retractor is axially movable between an extended tissue-engaging position and a retracted position. There is an open passage into which the retractor moves when moving from the extended to the retracted position. The retractor has a distal end portion constructed to engage tissue and apply axial transporting force thereto while moving from the extended to the retracted position. The retractor is constructed to be advanced and retracted repeatedly to accumulate a series of samples in the instrument.

Abstract: This invention relates to a device for pressure fusing dry, powdered toner particles to a copy sheet in an electrostatic copier. The pressure fusing device comprises a rigid member against which fusing pressure can be applied and a plurality of independent, freely movable rollers for applying fusing pressure to a copy sheet.

Abstract: A spray controlling system is provided for vehicles that includes, for a wheel-set, a splash guard and a side shield positioned at the rear and side of a wheel set, respectively. The guard comprises a panel having a plurality of rows of conical projections and a plurality of upstanding ribs formed on a wheel-facing surface thereof in a spaced parallel relationship. Both projections and ribs are disposed in an inverted-V configuration oriented on a vertical centerline of the panel with six rows of projections interposed between adjacent ribs. The projections are disposed closely adjacent in the rows to form water flow channels between rows and ribs with the ribs being about twice the height of the projections.
