Abstract: A land grid array package or a ball grid array package is electrically connected by an elastomeric type layer (containing alternating elements of conductive and non-conductive silicone) to a printed wire board or motherboard. A hold-down collar engages the peripheral edges of the package and snaps into holes in the board in such manner as to create pressure on the elastomeric layer, causing the layer to compress and create through-going electrical paths between exposed lands or conductive elements on the bottom of the package and exposed conductive elements on the wiring board. In one embodiment, solder balls adhere to the exposed conductive elements on the bottom of the package. In this embodiment the collar is initially in two pieces which are fitted together to engage both the top and bottom edges of the substrate.

Abstract: A fitment for use as a pour spout for a paper carton or flexible bag for liquids and powders has a flange which may be welded around a hole in the carton. A spout projecting outward from the flange is provided with a removable membrane integral with an inward projection positioned on the interior of the spout approximately midway of its height. Preferably the membrane is concave. A horizontally disposed pull ring is attached to the membrane by a connector so that pulling the ring removes the membrane by fracturing the tear line at the juncture of the outer edge of the membrane and the projection. A cap snaps over the spout and may be removed by unscrewing the complementary threads on cap and spout. A tamper-evidencing band frangibly connected to the lower edge of the cap skirt engages the exterior of the spout so that the cap cannot be removed without breaking the fragible connection.

Abstract: A ring is shaped to fit over the nose of a dental x-ray machine to direct the x-rays to the desired portions of the patient's mouth. Known film retainers which support x-ray film packets at the desired location behind the gums have handles which extend outside the mouth. The ring has adjustable means to fit onto the handle to adjust the position of the ring relative to the film both angularly and distance-wise. An adapter may be used to connect the ring to the handle of the retainer. Alternatively, the handle may slide through an aperture in a tab fixed to the ring.

Abstract: An umbrella of the type having a canopy that is fastened to a folding radial frame with hinged ribs radiating from a center pole, and a sliding catch which pivotally supports the braces of said ribs is disclosed. Secured between the sliding catch and the ribs is the reinforcing guy assembly. This assembly consists of elongated strings having its inner ends connected to said sliding catch and its outer ends connected to the outer ends of said ribs, and suspender means having its lower ends connected to said elongated strings and its upper ends connected to said ribs.

Abstract: A quick release clamp mechanism (10) including a pair of slide lock plates (12, 14) for engaging a series of guide screws (32) extending down from a bonnet or end plate (16) and through openings in a valve body flange (18). Toggle clamps (40) releasably engage one of the guide screws (32') and thereby can slide the slide lock plates (12, 14) by pivoting of a toggle lever (76). Sliding of slide lock plates (12, 14) causes a neck down region of openings (34) in plates (12, 14) to capture the heads of guide screws (32) and clamp bonnet plate (16) to valve body flange (18).

Abstract: As an open upper end apertured panel carton is conveyed to the fitment application stage of a filling line, a ramp raises the carton to a predetermined elevation. A rotary anvil having spuds on which fitments are applied which lowers a fitment inside the carton is indexed into precise angular position by an apertured collar fixed to the anvil sleeve, mating with a stationary pin. The sleeve on which the anvil is mounted is moved longitudinally so that the spout end of the fitment extends out through the aperture in the carton panel and a peripheral flange on the opposite end of the fitment engages the inside of the apertured panel. As a welding horn moves into position, extending fingers engage the loading and trailing sides of the carton to horizontally align the carton. Thus the aperture in the carton is vertically and horizontally aligned and the fitment is aligned with the aperture in the carton. The fitment flange is welded to the interior of the carton.

Abstract: A leaf type spring is used to hold a heat sink in contact with a chip or other heat-emitting component. Such a component may be mounted on a PCB or other element. A bolster plate is positioned below the PCB and two pins extend up from the bolster plate, through the PCB and through the base of a heat sink. A preferred heat sink has plural fins extending up from the base. In one form of the invention the pins extend above the level of the outer ends of the pins. A spring extends diagonally across the ends of the fins. Slots in the ends of the spring engage necks formed near the ends of the pins. In another form of the invention the fins are milled or otherwise formed with a groove extending diagonally across the heat sink and the spring fits into the slot. The pins extend only a short distance above the base of the heat sink and are necked to receive the slotted ends of the spring. In both forms of the invention intimate contact of the base with the heat emitting component improves heat transfer.

Abstract: A fitment comprising a pouring spout having a peripheral flange at one end and a closure at a second end is attached to a paperboard carton formed with a hole in a side panel. The carton is moved intermittently along a conveyor, such as that used in a filling machine. An arm having a spud oscillates about a horizontal axis parallel to the conveyor. The arm is pivoted to down position as the carton reaches the fitment attaching station so that the fitment enters the open end of the carton with the spud aligned with the carton hole. The arm is mounted on a first carriage which reciprocates horizontally in a first direction to project the closure through the hole until the flange abuts the inside of the carton panel. An ultrasonic welding horn is mounted on a second carriage which reciprocates in alignment with the first carriage in a second direction opposite the first direction. The horn welds the fitment flange to the inside of the carton panel.

Abstract: Computers are manufactured with connectors in which are inserted at least one PCI expansion card to increase the capacity of the computer. A computer enclosure panel is formed with an opening for insertion and withdrawal of the card. The card has a cover which blocks the opening after the card has been plugged in. The invention provides a retainer mounted on the rear panel which, when projected, engages the cover to assist in holding the card in place. The slide has a detent which is manually disengaged in order to slide the cover to retracted position. It further provides room for the tab conventionally extending outward of the card so that the card may be located closer to the side panel, thereby conserving space within the enclosure. Computers as shipped from the factory many times are not provided with PCI cards and the opening is blocked by a removable blanking cover. The slide also holds the blanking cover in position.

Abstract: Because of space limitations, a small heat sink and a fan (of about 2".times.2".times.1/2" size) is used to cool to below 105.degree. C. (at an ambient temperature of about 40.degree. C.) a CPU chip (of about 16 mm.times.16 mm size) which uses about 30 watts current and is mounted on a motherboard of considerably larger size. A heat transferring thermostrate washer covers the chip and a pad covers the washer. Soldered to the pad is a square heat slug. Studs extend upward from the slug. The studs fit through holes in the base of the heat sink. The heat sink is of the type having plural rectangular cross-section fins extending upwardly from the base. Above the heat sink is a fan attached to the motherboard by screws at its four corners extending through heat slug and into the motherboard.

Abstract: Motherboards and cards (herein "boards") mounted in computer enclosures must be supported on X, Y and Z axes to resist shock and vibration. This requires that four edges of the board be supported. Because of the high cost of such boards their lengths are made as small as possible, and this dimension is the direction of insertion of the board. A guide is attached to the leading edge of the board having a depending foot which engages fasteners formed on the base of the chassis of the enclosure. Thus the inner edge of the board is supported along two axes. Two side edges of the board are held in tracks and the outer edge is held at the point of insertion.

Abstract: A cover for a rectangular enclosure is pivoted to the rectangular base at the front, swings rearwardly-downwardly and engages the back of the base. A CD drive installed in the base is accessible from one side. For the purpose of inserting CDs and providing access for CD controls and jacks, a base window is formed in the side of the base and its edges are framed with a bezel which projects slightly outward from the base side. The cover has a cover window in one side congruent to the base window but spaced outward so that, as the cover is swung closed, the cover window is displaced outwardly relative to the bezel and the bezel does not interfere with closing the cover.

Abstract: A seat cushion system that reduces the vertical impact to the seat occupant within the space and cost constraints of existing seat support structures. In one embodiment, the seat cushion employs a series of layers of varying density and lateral displacement foams with a rigid or semi-rigid material within the cushion. Each layer of foam can change in both density and lateral displacement depending on the volumetric space available. Another embodiment demonstrates how only two layers of differing densities and lateral displacement can greatly reduce the impact force from vertical thrust.

Abstract: An internal fitment has a bottom peripheral flange adapted to be ultrasonically welded or otherwise attached to a panel of a paperboard carton surrounding a hold in such panel. Above the flange is a spout which converges upwardly and has a cylindrical external locking bead. Above the spout is an outward slanted tear band and above the tear band is a reclosure cap having a top, a depending skirt formed with internal interrupted beads and a plug. The tear band is connected to the spout and cap by thin horizontal tear lines. A finger grip tab extends outwardly of downward with respect to the tear band so that the consumer may conveniently grip the tab, pulling it circumferentially around the spout to separate the tab from both spout and cap. The cap is dimensioned so that the skirt fits over the outside of the spout, the beads detachably locking under the locking bead. The plug seals against the inside of the spout to prevent spillage.

Abstract: A flashlight holder is described which can be used with differently sized flashlights. The holder includes vise grip pliers for gripping structure adjacent a location it is desired to illuminate. A connector of the holder includes a collar for one size flashlight, as well as two rings for flashlights of other sizes. A bolt is threaded within the collar and acts as an adjustment mechanism for connection to any one of the differently sized flashlights. An interface device which secures the connector to the vise grip pliers facilitates the holding of flashlights or other objects of different weights. Its construction includes a mating ball and socket structure cap and a housing for a bolt on another adjustment mechanism provided as part of the vise grip pliers. The housing and cap are so secured together by bolts that tightening or loosening them changes the resistance to movement of the ball within the socket and movement of the interface device relative to the vise grip pliers.

Abstract: A tamper-evident, snap-on, screw-off closure which is used with a specially shaped container neck is provided with a foil liner. Once the closure is applied to the neck, the foil liner is sealed to the neck of the container. The foil liner includes a tab for removal of the seal disc from the neck. The closure is characterized by the absence of a second liner between the top of the cap and the foil liner. The closure, neck and the foil liner are formed to inhibit adherence of the tab to the cap interior and the neck exterior.

Abstract: A tamper-evident closure and specially shaped container neck. The closure has an upper skirt with an engagement structure on the interior of the skirt which cooperates with an engagement structure on the neck. The closure and neck have tamper-evidencing portions which interengage when the closure is seated on the neck to prevent removal of the closure with the tamper-evidencing portions intact. A tear tab reinforced with a vertically extending bend is joined to the tamper-evidencing portion of the closure. The neck has at least one notch shaped and positioned to receive the tear tab when a cap is applied to the neck.
