Abstract: A drive train for the sleeve of a sleeve valve engine has a pair of drives imparting compound motion to the sleeve which gives improved port opening and closing. One drive uses a engine driven first gear to give eccentric motion to the sleeve by a cam and follower. The other drive uses an engine driven second gear to give a small simultaneous rotation to the sleeve by an eccentric pin during a split sleeve. One drive allows axial response without preventing rotational response from the other drive. The sleeve path allows tall narrow ports which allow the piston rings to be nearer the piston crown and this reduces emissions.

Abstract: An implantable device includes a housing, a circuit board having a plurality of through holes, and a plurality of interconnect pins within the housing and oriented perpendicular to a major surface of the housing. The circuit board is connected to the interconnect pins such that the pins extend through the through holes of the circuit board.

Abstract: A position-estimating receiver, that receives ranging signals that are transmitted by multiple sources that modulate the signals with pseudo-random unique to the respective sources, includes data correlation channels, each of which correlates the incoming signals with a replica of the code used by a selected source to acquire the signal from the source in an acquisition mode and tracking the acquired signal in a tracking mode. The receiver detects possible spurious correlations in one or more monitor channels, each of which correlates the incoming signals with the code replica in use by a data channel in the tracking mode, stepping the replica through a succession of code phases other than the phase in the data channel and, if a significant correlation output is detected, causes the data channel to return to the acquisition mode.

Abstract: High melting temperature Pb/Sn 95/5 solder balls are connected to copper pads on the bottom of a ceramic chip carrier substrate by low melting temperature eutectic Pb/Sn solder. The connection is made by quick reflow to prevent dissolving Pb into the eutectic solder and raising its melting temperature. Then the module is placed on a fiberglass-epoxy circuit board with the solder balls on eutectic Pb/Sn solder bumps on copper pads of the board. The structure is reflowed to simultaneously melt the solder on both sides of the balls to allow each ball to center between the carrier pad and circuit board pad to form a more symmetric joint. This process results in structure that are more reliable under high temperature cycling.

Abstract: This invention relates to a polymer mixture which comprises an aromatic polycarbonate (A); a styrene (or styrene derivative and/or (meth)acrylate) containing polymer or copolymer and/or a styrene (or styrene derivative and/or (meth)acrylate) containing graft polymer (B); phosphorous compound(s) which are phosphate or phosphonate or oligomeric or poly-phosphate based flame-retardant(s) (C); specific inorganic additive(s) (D); and further flame retardant(s) or anti-drip agent(s) (E): and optionally, other additives.

Abstract: Two substrates are produced each with a planar, mirror-image matrix of metal contacts in a surface wiring layer. The substrates are positioned with the matrices in parallel confrontation which defines pairs of confronting contacts. A metal ball is positioned between each pair of contacts with a respective volume of joining material between the ball and each of the two respective contacts. The volumes of joining material are simultaneously melted to allow surface tension to align the substrates and to accurately center the balls between each respective pairs of contacts in a plane defines by the matrix of balls.

Abstract: A hand-held kitchen utensil having a manually operable rotary drive mechanism including a helical grooved spindle housed within a tubular protective sleeve. The drive mechanism is actuated by the alternate application of a substantially vertically directed downward force which slidably displaces the sleeve. Upon removal of said force, a restoring spring force returns the protective sleeve to its initial position. This reciprocal sleeve movement is effective for rotating the spindle and an attached circular blade in respective clockwise and counterclockwise directions. A plurality of arcuate support bands extend from the circular blade and form auxiliary food mixing elements. The invention also encompasses the selective utilization of interchangeable blades which can be attached for specific food processing requirements.
