Abstract: A sterile or sterilizable container in which the contents are sealed has a wall provided by a rupturable membrane. Preferably the outer surface of the membrane is covered by a layer of sheet material peelably adhered thereto. To dispense the contents, another rupturable sheet is adhered to the membrane, having first removed the covering layer if present. The surface of said rupturable sheet remote from the membrane is sterile, and a sterile cutting tool is used to cut through the two rupturable layers to create an opening through which the contents can be discharged. The potentially contaminated outer surface of the container membrane is thus sealed to the adjacent surface of the rupturable sheet, which could also be contaminated, thereby minimizing the risk of such contamination being passed to the contents as they are dispensed from the container.

Abstract: A rotary feeder has a valvular rotor rotating on an axis in a cylindrical cavity. A plurality of rigid, free-floating blades project from a hub of the rotor to delimit several material-receiving pockets circumferentially distributed over the hub. The inner edges of the blades rest in axial recesses in the hub and are supported by fixed projections extending outwardly from the hub along the trailing side of the blades. The recesses permit limited angular movement of the blades relative to the hub. The blades have widths from the hub to the periphery of the cylindrical cavity greater than corresponding radii through the inner edges of the blades at the hub, whereby the blades are angularly inclined relative to such radii. Top portions of the blades are applied to peripheral wall portions of the cylindrical cavity. The recesses, the fixed projections, and peripheral wall portions of the cylindrical cavity cooperate to hold the blades in position.

Abstract: To improve smoothness of tape transport in a spiral path over a guide cylinder, the guide rollers located immediately adjacent the guide cylinder, and journalled to rotate about an axis inclined with respect to the axis of the guide cylinder, can rotate about respective axes of rotation which are variable with respect to the axis of inclination defined by the bearing means journalling the guide rollers to permit self-balancing and self-adjustment of the spiral path of the tape about the cylinder during operation of the apparatus in dependence on the forces applied by the tape on the immediately adjacent rollers. Variation of the axis of rotation can be obtained by providing a central bearing for the roller about its axis of rotation, the bearing having a slight amount of play, and being offset with respect to the center of the tape passing around the roller to direct the edge of the tape against a guide surface and provide a fixed bias force on the bearing.

Abstract: Stapler having a vertically-adjustable cap for selecting a staple-driving force.

Abstract: Metallic workpieces, such as the terminals of a direct current motor armature winding, are welded to a slot, such as a commutator slot, using high frequency vibratory energy. A half wavelength resonator including a tip having a cutting surface is disposed opposite a slot containing the workpieces. As an applied force urges the tip into relative motion with respect to the slot, the cutting surface cleaves a sliver from the slot wall, the sliver being urged by the tip into intimate contact with the workpieces to be welded. When the resonator is rendered resonant for undergoing high frequency vibratory motion in a direction normal to the applied force the sliver and workpieces are welded together and to a surface of the slot.
