Abstract: A plural-layer body-contacting protective and cushioning interface structure. This structure has a body-facing side which contacts the body, and an opposite side, and intermediate these sides, in one form of the structure, is a moisture-wicking layer, next a moisture-blocking, gas-permeable barrier layer adjacent the moisture-wicking layer, and next, an acceleration-rate-sensitive cushioning layer. In some applications, the moisture-wicking layer is omitted.

Abstract: An EMI containment assembly for an integrated circuit chip. A frame forms an eletrically conductive wall around the perimeter of the integrated circuit chip. The bottom of the frame makes an electrically conductive contact with a ground trace on the printed circuit board to which the chip is mounted. The top of the frame makes an electrically conductive contact with an electrically conductive heat removal assembly that is disposed over the top of the chip. An electrically conductive bolster plate is mounted on the side of the printed circuit board opposite the integrated circuit chip and is disposed beneath the chip. Because each component of the assembly is electrically conductive, the assembly creates an EMI cage around the integrated circuit chip. Because the frame does not cover the top of the chip, it does not interfere with a thermally conductive contact that is made between the top of the chip package and the heat removal assembly.

Abstract: A heatsink for use with an actively cooled daughterboard system. Plural transverse fins are integrally formed with a base portion. The fins are parallel to one another and orthogonal to the bottom of the base portion. The fins have a constant profile relative to the bottom of the base portion, but the base portion has a central portion that is thicker than its end portions. The thickness of the central portion varies according to a radius. The radius is approximated by step differences in the depths of the fins.

Abstract: An actively cooled daughterboard system. One more daughterboards are mounted in parallel rows on a motherboard. Each daughterboard is oriented substantially perpendicular to the motherboard, but may optionally be mounted at an oblique angle relative to the motherboard. Each daughterboard has a low-profile thermally-efficient heatsink mounted thereon. A fan shroud partially covers the daughterboards, but has openings in its sides for directing air flow through plural fins on the heatsinks and through a fan mounted to the top of the fan shroud. The inventive daughterboard system enables multiple high heat dissipating daughterboards to be placed closer together than the daughterboard systems of the prior art while still keeping the daughterboards adequately cooled. Moreover, because only a single fan is used to cool all of the daughterboards under the shroud, noise and expense are reduced relative to prior art systems that employed one or more fans per daughterboard.

Abstract: A heatsink for use with an actively cooled daughterboard system. Plural transverse fins are integrally formed with a base portion. The fins are radially displaced from one another. The base portion includes a central portion that is thicker than the end portions. The thickness of the base portion and the profile formed by the outer ends of the fins vary according to radii. The inner radius associated with the central fins is shorter than the inner radius associated with the endmost fins.

Abstract: This pneumatic stroke reversal system for reciprocating, linearly driven pumping units is completely automatic in its cyclic operation, and greatly improves efficiency. A smaller drive motor is required because kinetic energy is stored at the end of each stroke, to be returned to the system to assist in beginning and accelerating the following stroke, and because the smooth and controlled reversals allow a substantially higher stroke velocity and production from a unit of a given size. The reversals are effective on both the upstroke and the downstroke, and their maximum net values are individually selectable over a wide range, and adjustable in the field. The exact points of direction change occur at the instant of maximum rod stretch and maximum rod contraction, respectively, thereby greatly reducing parasitic rod string oscillation, and reducing pressure peaks on, and problems with, the rod string.

Abstract: An apparatus for latching to any selected one of a family of electrical switching apparatuses having differently located centers of gravity includes a lifting bracket having a plurality of lifting attachment points whereby a crane or other hoisting device may be attached thereto. The lifting bracket with lifting attachment points enables the selected electrical switching apparatus to be lifted while being maintained generally level without excess tilting thereof. The apparatus also includes first and second latches movably connected to opposing ends of the apparatus for securely latching to the electrical switching apparatus being lifted. The lifting bracket of the apparatus also includes a locking flange for engaging the electrical switching apparatus during lifting and securely locking the first and second latches to the electrical switching apparatus.

The lifting assembly also includes a winch having a spool, and a cable having a first end attached to the winch and a second end for lifting the electrical switching apparatus. The cable passes over a pivotable, rotatable cable support member mounted upon the support frame to provide even distribution of the cable on the spool. A plurality of wheels rotatable about either a horizontal axis or vertical axes are attached to the support frame for movement of the support frame along the rail members.

Abstract: The inventive mechanism conducts heat through the leads of the connector to the solder connection points, and simultaneously reflows all of the solder on all of the pads. The inventive mechanism comprises a machined aluminum piece that mimics the mating geometry for the connector and couples to the connector as if it were a chip device. The inventive mechanism couples to the connector via heat conducting fins. Heat is transferred to the aluminum piece, and down through the fins and into the internal portion of the connector. The fins contact the internal portion of the connector leads. Thus, heat is transferred from the internal portion of the leads to the exterior portion of the leads, and down to the soldered connection point with the PCB board. Since the fins contact all of the internal leads of the connector, each of the soldered connections is reflowed at approximately the same time, and thus, the connector is then removed from the board.

Abstract: Disclosed are new coatings compositions based on an HDI isocyanurate or biuret polyisocyanate and a bis(imine) reaction product of a diaminoalkane containing between two and five carbon atoms with an alkyl aldehyde containing between four and seven carbon atoms (advantageously a bis(imine) product of the reaction of 1,4-diaminobutane and isobutyraldehyde). The latter bis(imine) is completely miscible in HDI isocyanurate and biuret polyisocyanates, and, as a reactive diluent, allows the preparation of high performance coatings formulations that require only small amounts of solvents to achieve a conveniently sprayable viscosity.

Abstract: A formulation incorporating maltose or maltose corn syrup which allows increased levels of fructose or high fructose corn syrup to be infused into fruit or fruit pieces before drying. The formulation decreases the stickiness associated with high fructose infusion and agglomeration of fruit. Use of the formulation eliminates the need to oil coat fruit to keep it free-flowing. The formulation provides for retention of the original product character (size and shape) by requiring less quantity of water to be removed by dehydration since the fruit water is replaced with infiltrant. With a greater amount of the less costly infiltrant to be sold per amount of fruit, the cost of the product is thereby reduced. The texture of the finished product remains pliable due to the amount of humectant present. The sweetness intensity which would overwhelm the original flavor of the fruit product at these levels is reduced along with possible volatile retention.

Abstract: An exonuclease-based method for joining and/or constructing two or more DNA molecules. DNA fragments containing ends complementary to those of a vector or another independent molecule were generated by the polymerase chain reaction. The 3' ends of these molecules as well as the vector DNA were then recessed by exonuclease activity and annealed in an orientation-determined manner via their complementary single-stranded regions. This recombinant DNA may be transformed directly into bacteria without a further ligase-dependent reaction. Using this approach, recombinant DNA molecules are constructed rapidly, efficiently and directionally. This method can effectively replace conventional protocols for PCR cloning, PCR SOEing, DNA subcloning and site-directed mutagenesis.
