Abstract: A receptacle for disposal of used, sharp, medical instruments or other biohazards, comprising an upright container, which is closed except for a slot in a top wall, a chute which is mounted integrally to the top wall so as to extend downwardly, a shroud, which is mounted integrally to the top wall so as to extend upwardly, and a scoop, which is mounted pivotally to the top wall at a back margin of the slot. The scoop and shroud are configured so as to form a tray, which is adapted to hold one or more such instruments until the instruments held by the tray are discharged through the slot, via the chute, into the container. The scoop, shroud, and chute are configured so as to impede an object, such as a person's finger, which may have been inserted through the slot from reaching any such instruments in the containers. The scoop and chute are configured so as to impede any liquid contents of the container from splattering outside the receptacle.

Abstract: A clutch pressure modifier valve for an automatic control circuit for a power transmission mechanism in a vehicle driveline wherein provision is made during ratio changes that requires engagement of a fluid pressure operated transmission clutch for modifying a clutch engagement pressure to compensate for the effect of centrifugal pressure build up in the pressure chamber of the clutch structure due to rotation of the clutch at high speeds during a shift interval whereby the timing of the clutch engagement is relatively independent of the rotary speed of the clutch during engagement and whereby the torque capacity of the clutch more closely matches the torque requirements of the driveline during ratio changes.

Abstract: In accordance with the present invention an open top railway car is provided in which the car body is divided longitudinally into at least two body sections having opposite ends which are pivotally mounted on vertically extending supports attached to a car underframe. The body sections include respective transversely spaced side walls, at least one end wall, and bottom walls having inner edges which abut and/or overlap in closed position to define the bottom of the car. To achieve increased volumetric carrying capacity, the bottoms are horizontal and extend outboard of the wheels. Each of the body sections is pivotable from the closed position to an open position in which the inner edges of the bottom walls are spaced apart to allow discharge of lading between the rails. An energy saving unloading system is also disclosed for unloading the cars.
