Chip stacks with decreased conductor length and improved noise immunity are formed by laser drilling of individual chips, such as memory chips, preferably near but within the periphery thereof, and forming conductors therethrough, preferably by metallization or filling with conductive paste which may be stabilized by transient liquid phase (TLP) processes and preferably with or during metallization of conductive pads, possibly including connector patterns on both sides of at least some of the chips in the stack. At least some of the chips in the stack then have electrical and mechanical connections made therebetween, preferably with electroplated solder preforms consistent with TLP processes. The connections may be contained by a layer of resilient material surrounding the connections and which may be formed in-situ. High density circuit packages thus obtained may be mounted on a carrier by surface mount techniques or separable connectors such as a plug and socket arrangement. The carrier may be of the same material as the chip stacks to match coefficients of thermal expansion. High-density circuit packages may also be in the form of removable memory modules in generally planar or prism shaped form similar to a pen or as a thermal conduction module.

A rotor puller has two arm members, ending at claws, and a jack with an extendible piston. The arm members and the jack are pivotably attached together about a pivot axis. Springs bias the arm members toward each other. The claws are placed over a brake rotor and retained thereon by a pin. After the claws have been placed, the jack is centered and activated to extend the piston towards the claws. The piston forcibly engages a wheel hub while the claws forcibly engage the rotor, pulling it from the wheel hub. Handles on the arm members facilitate placement of the claws over the rotor.

An apparatus and process is disclosed for the separation of solids from gases in a mixture which is most particularly applicable to an FCC apparatus. The mixture of solids and gases are passed through a conduit and exit through a swirl arm that imparts a swirl motion having a first annular direction to centripetally separate the heavier solids from the lighter gases. The mixture then enters a cyclone which has a curved outer wall and imparts a second swirling angular direction to the mixture. The second angular direction is counter to the first angular direction. The apparatus and method assures that a greater proportion of the mixture entering the cyclone is incorporated into the vortex to further enhance separation between the solids and gases.

A comb made up of a handle wherefrom a number of sweeping teeth are projected, thus forming a rigid set of high mechanical strength, where the teeth are aligned one after the other with a minimal separation in between to define the comb front, keeping the anchorage section of each tooth within the handle body, and projecting out of the handle in a length considerably greater than the anchorage length. The teeth have a proximal section starting from their anchorage inside the handle to a point of their total length outside the handle, where a distal section begins and extends up to the free end, and where the surface roughness of the former section is different from that of the distal section, which is microtexturized.

In one exemplary illustrative non-limiting aircraft radio communications system, a “POCI” (“Presence Of Communication Interlock”) is comprised of a double balanced low pass LC filter covering the voice range. The voice signals coming from the two VHF's are filtered and processed by an amplifier at an adequate level to be peak detected. The resulting signal is applied to an amplifier with a defined hysteresis and time constant and finally drives the relay interlock circuit that inhibits an ACARS VHF radio from transmitting whenever other on-board comm. VHF transceivers are receiving voice signals. Visual indicators provide information on system operation and system power failure.

An intake tube for an air intake system of a vehicle is provided. The air intake system is located upstream of an intake manifold and includes an intake enclosure and an air precleaner. The intake tube directs a flow of air from the intake enclosure to the air precleaner. The intake tube comprises a first end section, a second end section and a curved section. The first end section is connected to the intake enclosure and has a first longitudinal axis. An inner surface of the first end section defines a first section air passage. The second end section is connected to the air precleaner and has a second longitudinal axis. The inner surface of the second end section defines a second section air passage.

The curved section includes a compressed portion having a minor dimension and a major dimension. The major dimension is greater than the minor dimension so that the flow of air through the curved air passage has minimal separation which increases flow rate into the air precleaner.

The present invention relates into a device and method for controlling distribution of superparamagnetic nanoparticles (NPs) in a microfluidic chamber. By applying a strong magnetic field, localization of the NPs to inter-pillar spaces between soft magnetic coated micropillars is demonstrated, even with a modest fluid flow across the inter-pillar space. Flow splitting techniques are also provided to force particles to reliably interact with the NPs, specifically by using a Brevais lattice with a primative vector of 1°-15° with respect to flow direction. The pillars may have non-circular cross-sectional shape and be arranged to direct NP clouds more effectively. An array of the pillars has multiple axes for rotating NP cloud distributions in multiple orientations, allowing for a rotating magnetic field to move the NP cloud for mixing a fluid that is otherwise stationary.

Methods, systems and computer program products for mapping is a set of related objects into a multidimensional space. The mapping is carried out using an iterative (e.g., pairwise) refinement strategy that attempts to ensure that the distances of the objects on the map satisfy a supplied set of upper and lower bounds. In a preferred embodiment, these upper and lower bounds are derived from a supplied set of relationships (similarities, dissimilarities, or proximities) between the objects. In another preferred embodiment, these distance bounds are chosen to preserve local relationships between neighboring objects while maintaining minimum separation between remote objects.

Stress-relieved molded acrylic opthalmic lenses, and injection-coining mold processes for molding stress-relieved plus and minus to high-minus diopter ophthalmic lenses of optically superior acrylic resin, able to pass standardized impact drop tests for use as eyeglass lenses, are described. The injection-coining processes use two-plate and three-plate mold assemblies. The cavity of a two plate runnerless mold is partially filled under partial tonnage, and the movable half of the mold controlled to coin and densify the acrylic resin under secondary or full tonnage, when a velocity-pressure changeover point is reached. In a process which employs a three-plate mold assembly, the lens mold cavities are partially filled under less than total clamp tonnage, with a cavity plate held by hydraulic pressure against a movable half of the mold. The mold assembly is then closed under full tonnage when a velocity-pressure changeover point is reached, collapsing the cavity plate a stationary platen, bringing the mold assembly to a total stack height. The processes produce impact resistant acrylic ophthalmic lenses which are stress-relieved and without weld lines, even in the high minus diopter range, with center thickness' as low as one millimeter, and edge thickness' up to ten millimeters.
