摘要:
A mold press comprising a force equalizer independent of the mold platens. The force equalizer consists of a pair of plates defining a cavity therebetween. The cavity is filled with a force distributing material, such as hydraulic fluid. An opening is provided through the force equalizer to provide the extruder access to the mold plates. This opening is surrounded by a floating seal which permits movement of the equalizer plates with respect to the seal. The cavity is designed to extend beyond the chase footprint areas by an amount dictated by the size and relation of the footprint areas to one another.

A dual inlet microchannel device and a method for using the device to perform a flow-through kinetic assay are described. A microplate having an array of the dual inlet microchannel devices and in particular their specially configured flow chambers is also described. Several embodiments of the dual inlet microchannel devices and specially configured flow chambers are also described.

A conveyor sprocket assembly generally includes a support shaft, at least one conveyor sprocket slidably engaging the support shaft, and an abutment stop positioned adjacent the conveyor sprocket. The abutment stop is configured to be removed to allow the conveyor sprocket to slide axially along the support shaft.

An optical fiber splitter has a higher density fiber optic array that allows for smaller packaging. The optical fibers that extend from the optical fiber splitter have one end connectorized and their spacing at the other end reduced, thereby eliminating components that were heretofore required. A method of making the fiber optic array includes interleaving the optical fibers to reduce the overall dimensions of the fiber optic array and the fiber optic splitter. A tool is used to reduce the spacing of the optical fibers in the fiber optic array.

A cable clamp assembly and a cable clamp method for a flat fiber optic cable are disclosed. The assembly includes a wedge-shaped outer shell with a bottom wall having a friction inner surface with a longitudinal central recess formed therein. The flat fiber optic cable resides within the interior of the outer shell and is supported by the friction inner surface. A shim having two parallel rows of protrusions fits within the interior of the outer shell with the protrusions being in contact with the fiber optic cable. The assembly includes a wedge insert having two outer ridges that substantially align with the two rows of protrusions. When the wedge insert matingly engages the outer shell, the outer ridges press down on the protrusions, which in turn press down on the fiber optic cable mainly at the locations where longitudinal dielectric strength members reside.

摘要:
Apparatus and methods for improving the control of the temperature of a supported member, such as a substrate, in high vacuum processing systems, such as ion beam etch (IBE) systems. The apparatus includes thermoelectric devices that transfer heat from a support member supporting the supported member to a liquid-cooled heat exchange member to regulate the temperature of the support member. The method includes cooling the support member with thermoelectric devices that transfer the heat to the liquid-cooled heat exchange member.
摘要:
A closed flow-through microplate is described herein that can be used to perform high-throughput kinetic flow-through assays to detect biomolecular interactions like material bindings, adsorptions etc. . . . that is helpful for example with testing new drugs. A method for manufacturing the closed flow-through microplate is also described herein.
摘要:
A device for removing heat from a fiber-optic package having at least one optical element includes a terminated fiber for diverting excess optical power away from the optical element and an energy dissipating element having a capability to absorb the optical power from the terminated fiber and a high thermal conductivity sufficient to distribute heat generated from absorption of the optical power.

Methods and apparatus for ultrasonically scanning cylinders are provided. The methods and apparatus employ as few as one ultrasonic sensor for full immersion scanning and defect detection. Self-centering fixturing spins the cylinder, reducing vibration, allowing for fast ultrasonic scans. To create the 45 degree angle beam shear waves for the circumferential scans, the ultrasonic sensor is offset from the centerline of the cylinder, creating the correct angle for excitation of the shear wave.
