    摘要： A self-propelled upright vacuum cleaner is provided having a lower portion and an upright handle portion pivotally attached to the floor engaging portion for a pivotal motion between an upright storage position and a pivotal operating position including a transmission operatively connected to a drive wheel and a motor drivingly connected to the transmission for driving the drive wheel in forward and reverse. A clutch engaging member is pivotally mounted to the floor engaging portion adjacent to the transmission for pivotal motion about a pivot axis located generally at a forward portion of the clutch engaging member. Operably associated with the clutch engaging member is a transverse linking member that reciprocates from a neutral position in first and second directions in response to pivotal motion of a bottom link. The reciprocation of the transverse link selectively moves said clutch engaging member from a neutral position to a forward drive position and a reverse drive position. A finger link member carried on the housing assembly is selectively positioned in a channel formed on the bottom link, relative to the pivotal positioning of the housing assembly. Pivotal motion of the finger link engages the bottom link member when the housing assembly and handle portion are in an operative inclined position and does not engage the bottom link member when the housing assembly and handle portion are in a storage upright position.

    摘要： An apparatus for separating gas bubbles that may be entrained in perfusate flow prevents such bubbles from continuing downstream and entering an organ or tissue. The apparatus may include a chamber having a top wall, a bottom wall and side walls. The chamber may include an inlet configured to allow at least one of gas and liquid to enter the chamber, an air opening configured to allow at least gas to exit the chamber and a first liquid opening configured to allow at least liquid to exit the chamber. The apparatus may function as an accumulator that reduces or eliminates pulsatility of the liquid flow and pressure. The apparatus may include a minimum volume of gas, initially or through the accumulation of gas, such that flow and pressure fluctuations in the liquid are dampened or eliminated. The apparatus may include a sampling port in a wall of the chamber.

    摘要： A cleaning machine for cleaning a surface in which cleaning solution is dispensed to the surface and substantially extracted along with the dirt on the surface in a continuous operation is provided. The cleaning machine includes an airflow source that produces an airflow directed out of an outlet. A duct cover covers the outlet. The duct cover includes at least one opening that is sized and oriented to distribute the air evenly across the outlet.
