Abstract: A method for forming a three-dimensional object having complex passages, comprising the steps of forming a plurality of interlockable sub-objects capable of being assembled together to form the three-dimensional object, each sub-object having a portion of the complex passages and each having at least one joining surface for attachment to an adjacent sub-object, the interfaces between the sub-objects being chosen such that each sub-object may be formed by a simple, inexpensive molding process, for example, by compression molding or injection molding; applying a suitable joining material to the joining surfaces; and assembling the sub-objects to form the three-dimensional object. In applications wherein the joining material is heat-curable, the method may include the additional step of heat-curing the assembly. The joining material may be identical or not with the sub-object forming material.

Abstract: A thermoplastic carrier sheet is die-cut to have a size and shape matching that of a PEM bipolar plate. A plurality of holes are punched in the carrier sheet in the pattern of gasket beading to be formed subsequently. In a mold, liquid gasket resin fills the mold on both sides of the carrier sheet to form the gasket, flowing through the holes in the sheet and thereby causing the gasket to become mechanically attached to the sheet. A carrier element having a flange portion substantially identical with the outer profile of the bipolar plates is laminated to the sheet edge. During assembly of a fuel cell, the carrier element automatically positions the gasket correctly on the plate and prevents the gasket from twisting or shifting. In a currently preferred embodiment, a membrane electrode assembly is attached within an appropriate opening in the carrier sheet.

Abstract: Medical devices such as vein stabilizer devices and intravenous starter kits and methods of using the vein stabilizer devices are disclosed herein. One exemplary starter kit includes a vein stabilizer device and a tourniquet.

Abstract: A fuel and wastewater storage device for a fuel cell includes: a housing having an interior; a movable barrier dividing the interior into a first cavity and a second cavity; a fuel port located at the first cavity; and a wastewater port located at the second cavity, wherein the storage device is sized to be contained within a portable electric device. A fuel cell system includes: a fuel cell; a fuel and wastewater storage device in fluid communication with the fuel cell, the storage device includes: a housing having an interior; and a movable barrier dividing the interior into a first cavity and a second cavity.

Abstract: The present invention provides a method and system for simulating the effect on the frequency response of a transmission line due to the coupling of a second electrical network to the transmission line. It is observed that signals propagating through the second electrical network are reflected at the end of the second electrical network, thereby propagating back to the point of coupling with the transmission line causing partial cancellations of signals present. Thus, the second network effectively operates as a delay line, with an overall effect of creating nulls of various widths and depths in the frequency response of the transmission line. This second delay-line like network is replaced with a significantly simpler configuration.

Abstract: A door stop includes a mounting bracket for mounting to a swingable door, a base which is connectible to the mounting bracket, and a leg pivotally connected to the base and having an end for engaging a floor in an operative condition of the door stop. In one embodiment, the mounting bracket is detachably mountable to doors of different thicknesses and the base is detachable from the mounting bracket so that the door stop can be disassembled when not in use, and the base can be used with alternative mounting brackets. The base is preferably vertically adjustable relative to the mounting bracket and the leg can be releasably locked in a range of different angular positions. The door stop may optionally not include a mounting bracket with the base being attached directly to the door.

Abstract: A storage bin for compact discs in their native crystal boxes has an open top to permit viewing of the labels through the edges of the boxes, a forward sloping front wall to enable the boxes to be flipped for viewing the faces of the boxes, a guide extending downwardly from the base of the box dimensioned to be slidably received between the side walls of a like box so that the boxes can be stacked and slid with respect to one another, and an integral extension of the base for supporting a handle and a label frame. An optional divider partitions the bin to store two rows of tape cassettes.

Abstract: A fluid valve structure is provided having spaced first and second inlet sections connected to a source of pressure fluid and a plurality of side by side valve sections between said inlet sections, each having inlet, work and tank chambers intersected by a passage open at opposite ends to a control chamber and a tank chamber at a common pressure, a valve spool movable in said passage and having both ends at a common pressure and grooves adapted selectively to connect the work chamber to the inlet or tank chamber, a lever in the control chamber removably engaging one end of the spool and rotatable about a shaft transverse to the spool axis, and an external handle means operatively engaging the shaft to rotate the lever to move the spool axially in the passage, all of the spool, lever and shaft being fully enclosed with a valve housing in all operative positions.
