  • Patent number: 4155451
    Abstract: A disposable paperboard tray for retaining lading during transport and storage with a number of loaded trays stacked one on top of the other. The floor or bottom wall of the tray has a plurality of punched, spaced apart score lines or perforations which are not cut entirely through the floor whereby to provide a selective arrangement of protuberances on the bottom outside surface of the floor. When a plurality of trays carrying lading, such as conventional canned foods, are stacked one on top of the other, the protuberances engage the upper ends of the cans stacked in a nether tray to prevent one tray from sliding or inadvertently slipping one relative to its neighbor.

  • Patent number: 4155455
    Abstract: Non-destructive testing apparatus for rollers and the like of magnetic material comprises a pair of rotating spin rails having intermediate sections of magnetic material. Feeding apparatus deposits rollers on the spin rails and moves them successively past the magnetic sections. A magnet produces flux through the magnetic sections and a roller rotating thereon. Variable reluctance sensing apparatus senses changes in the flux. An eddy current test probe is positioned adjacent the magnetic sections. Variable reluctance and eddy current test circuits produce flaw output signals which control apparatus for segregating the rollers. Advantageously the feeding apparatus intermittently deposits successive rollers on the spin rails and intermittently moves the rollers along the rails in end-to-end relationship.

  • Patent number: 4155483
    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.

  • Patent number: 4155486
    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.

The plunger has a side orifice and discharge passage or duct through which liquid product can flow to be dispensed from a spray head. The piston is movable between high and low positions on the plunger to control the discharge through the latter. For the non-dispensing condition, the piston seals against an internal shoulder in the cylinder while a valve head at the lower portion of the plunger seals against and effects a slight deformation of a cooperable valve seat on the lower body portion of the piston, so as to provide an improved seal between the latter two parts.

  • Patent number: 4155491
    Abstract: The arrangement is mainly designed for transporting solid minerals from the floor of the ocean to a support vessel. The arrangement comprises an endless flexible carrier which is made of interconnected container sections. Each section has two chambers -- a load chamber and a float chamber. The arrangement also has means for batched loading of the chambers with solid mineral and compressed gas. During operation of the arrangement, the load chambers are loaded with solid mineral and the float chambers are filled with gas so that the loaded sections of the carrier acquire a positive buoyancy thus enabling displacement of the entire carrier.

  • Patent number: 4155492
    Abstract: An air cooled ceramic stopper valve and actuating rod for a bottom pouring ladle. Ceramic parts are assembled onto a metallic stopper rod which contains an enlarged head portion. The metallic stopper rod head is notched, so that refractory cement used to bond the ceramic parts forms a strong mechanical bond between the metal rod and the ceramic point of the valve. The notches provide enough strength in the joint between metal rod to ceramic point to permit shearing loose a frozen stopper valve by rotation (when the valve head [point] bonds to the ceramic orifice).

  • Patent number: 4155494
    Abstract: In a surgical glove package, the cuff of the glove is stretched around a packaging ring so that the glove cuff extends radially back towards the center of the ring. Also extending around the ring is a flexible, transparent liner covering the outside surface of the glove and between the glove cuff and the ring so that the cuff holds the liner securely to the ring. The glove is donned and removed from the ring by using the liner to manipulate the glove package. The glove package can also be used in connection with an inflating apparatus which inflates the glove prior to inserting a hand into the inflated glove. The glove package components are assembled by means of a standpipe and blower combination, which inflates the liner and facilitates stretching the glove cuff around the ring.

  • Patent number: 4155495
    Abstract: A conveyor for separating and aligning glass sheets moving along a sheet movement path includes a plurality of cylindrical rolls skewed relative to the movement path to displace the advancing sheets toward a side of the conveyor. At the side of the conveyor the sheets are aligned by an endless belt rotating through a path parallel to the sheet movement path. Each successive roll in the direction of sheet advancement has increasing peripheral surface rotational speed to separate the advancing sheets.

  • Patent number: 4155497
    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.

  • Patent number: 4155499
    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.
