  • Patent number: 5181886
    Abstract: A forming pin having a shank, a head, a point, and a pair of like grooves on opposite sides of the shank is made by gripping an elongate wire in a position wherein an end of the wire is exposed, forming a head at the exposed end of the wire while gripped, advancing the wire by a predetermined distance, and simultaneously forming the point and forming the grooves. The forming pin thus formed is severed from the remaining wire as the point and the grooves are formed. A pair of dies are used, which are movable so as to pinch the wire therebetween, along with mechanisms for closing the dies. The dies are configured similarly to define suitable forming edges.

  • Patent number: 5170531
    Abstract: Master carrier for a baton traversing drapery system comprises an elongated hanger adapted to be received in the horizontal gap of the conventional C-shaped type of traverse rod. The hanger element supports beneath the rod a platform having a rim along its outer edge which is inclined relative to the direction of travel. Spaced along the length of the inclined edge of the platform are a plurality of openings into which a drapery hook assembly can be installed and locked, by means of a clamp interacting with the rim of the platform. A pair of identical master carriers can be used to create an overlap in adjacent drapery panels without the necessity for using a projecting arm for this purpose. Attached to the outer face of the upper edge of the drapery is a baton which is attached to the drapery at substantially the point at which the drapery is suspended from the master carrier. Accordingly, when force is applied to the baton to move the drapery, little or no torque is created.

  • Patent number: 5165215
    Abstract: The present invention entails a method and apparatus for applying tamper evident bands to a container. In particular, the apparatus of the present invention directs a supply strip of banding material to a cutter which cuts the supply strip into a series of cut bands. From the cutter, the respective cut bands are, one at a time, transferred to a suction source and held. A form is passed adjacent the suction source and strips the cut band from the suction source. While the cut band is held within the form, a container is passed thereunder, and because of the spacing of the form and the position of the container, the container top or lid engages a portion of the cut band held within the form and strips the cut band from the form. Thereafter, the container and cut form are passed underneath a vibrating plate, causing the plate to engage the cut band and to properly position the same about the container for subsequent heat treatment.

  • Patent number: 5165145
    Abstract: A hinge mechanism is disclosed which is suitable for use on a pivotable character display for an electronic typewriter or portable computer. The hinge mechanism includes braking means for maintaining the character display in a viewing position, wherein friction is generated between disc shaped brake members of the hinge mechanism. Moreover, the addition of a cam in the hinge mechanism provides the selective use of torque to the braking means; the cam is engaged when the display is in a viewing position, preventing the display from slipping out of position, whereas the cam is not engaged when the display is near the horizontal, making it easier to raise and to lower the display. The hinge mechanism disclosed is suitable for use with multi-view position character displays as well as with single view position character displays.

  • Patent number: 5158503
    Abstract: A double-pivot door hinge is disclosed that is particularly suited for household appliances such as refrigerators or microwave ovens. The hinge arrangement allows the appliance door to be opened a full 180 degrees from its closed position without coming into contact with a flush mounted wall such as an abutting kitchen cabinet. The hinge has a first pivot pin and a stop arrangement which allows a door to be swung outwardly until a 90-degree position is reached whereby the stop arrangement is engaged. Upon further outward movement, the assembly shifts to a second hinge pin until a 180-degree position is reached. The movement from the 90-degree position to a 180-degree position requires the overcoming of a spring force of the hinge arrangement.

  • Patent number: 5155969
    Abstract: A food product packaging apparatus for a conveyor environment, and having a vacuum chamber operatively associated with the conveyor, which vacuum chamber is selectively moved into and out of a position in sealing engagement relative to the conveyor. A manifold, a vacuum source and conduit structure are included, the conduit structure connecting the manifold structure to the vacuum source and the vacuum chamber so that the vacuum source is selectively operable to draw a vacuum in the vacuum chamber through the manifold structure. A shuttle includes frame structure and drive structure for the frame structure so that the frame structure is movable in the direction of conveyor movement and, after a predetermined increment of movement, the frame structure shuttles opposite the direction of conveyor movement to a position to repeat movement in the direction of conveyor movement for a subsequent movement for the predetermined increment.

  • Patent number: 5152120
    Abstract: A latex lid mounting apparatus includes a seat body and a lid accommodating device with a replaceable lid container. A beverage cup is placed on a cup positioning plate. Lids are superposed in the container. An ascending assembly activates a lid holding unit to move up and down between an upper limit position and a lower limit position. The lid holding unit includes an outer ring, an inner ring journalled in the outer ring, several links connected to the inner and outer rings, and a plurality of paw elements carried on the inner and outer rings. A rotation control device regulates relative rotation between the inner and outer rings, so as to move the paw elements between an inner limit position and an outer limit position. Under the guidance of the rotation control device, the lid holding unit holds the lowermost lid immediately before reaching the upper limit position, while covering the open upper end of the cup with the lid immediately before reaching the lower limit position.

  • Patent number: 5144777
    Abstract: A grommet assembly for a wall panel and method of installation. The grommet assembly includes a grommet structure for insertion into the aperture made through a wall panel and includes pivotal locking arms for locking at the back face of the wall panel. An insert sleeve provides a circular wall that upon insertion into the grommet pivots the pivotal lock arms of the grommet. The insert sleeve is further provided with snap-engagement members that snap-engage to the circular wall of the grommet so that the grommet assembly is fastened together and to the wall panel. A retention ring may be used prior to cutting an aperture in the wall to secure fabric, or other wall coverings, around the aperture to be cut to prevent displacement or tearing, and to protect the outer wall surface.
