Granted: 1991-03-12
Abstract: Abstract PLASMA REACTOR AND METHOD FOR REMOVING PHOTORESIST      A plasma reactor comprises a working chamber that has at least one entry port.  The working chamber is adapted to receive at least one article.  The entry port is adapted to receive a working gas into the working chamber.  An elec-trical energy generator is provided.  The plasma reactor includes at least one pair of electrodes which are posi-tioned adjacent the working chamber entry port.  The elec-trodes, which are connected to the generator, create an electric field adjacent the entry port that converts the working gas into a working plasma for interacting with a material of the article.  The article to be processed is placed in a part of the working chamber which is free from electric fields.  An electric field-free region downstream of the plasma generating region is provided in which the article is positioned.

Granted: 1991-03-05
Abstract: ABSTRACT OF THE DISCLOSURE     A signature folder is disclosed in which a vacuum system is provided to prevent tail whipping of the signature when the direction of movement thereof is reversed.  The folder provides two counter-rotating cylinders.  A portion of the signature moves along the periphery of one cylinder and then reverses direction to move onto the periphery of the other cylinder.  A vacuum system is provided adjacent to the signature when it reverses direction.  The vacuum system includes a pair of guides and a central, freely rotatable vacuum roll.  The vacuum causes the reversing portion of the signature to move into engagement with the guides and roll and eliminates tail whipping.

Abstract: ABSTRACT OF THE DISCLOSURE        A vibratory concrete screed includes a frame and a sub-stantially horizontal screed blade.  A pair of end-mounted winches advance the screed along concrete forms into an area of unfinished plastic concrete.  A concrete spreading device is translated back and forth along the length of the screed to partially level the unfinished concrete before engagement by the screed blade.  The concrete spreading device includes grading means having distributing means in the form of an auger and metering means in the form of a plow.  The auger initially levels and redistributes the plastic concrete while the plow receives the plastic concrete from the trailing edge of the auger and regulates the level of plastic concrete discharged from the concrete spreading device and intercepted by the screed blade.          A carriage maintains the grading means at a predetermined eleva-tion in front of the screed blade and translates the spreading device along the length of the screed frame.  The concrete spreading device operates on the unfinished plastic concrete to feed a partially finished, constant height charge of concrete to the screed blade.

Abstract: Abstract of the Invention A biomedical implantable shunt is provided having an enlarged generally circular pump body and a perforated distal and proximal catheter attached to said body.  The catheters are intended to have excess length so they can be cut to proper length as necessary to fit a specific patient. The pump body includes a vestibule at the outlet end directly connected to the distal catheter.  A pair of one-way miter valves are provided within the pump body. The inlet valve is directly connected to the entrance provided for the proximal catheter while the outlet valve is positioned within the vestibule which is connected to the distal catheter.  A longitudinal ridge is provided in the base member of the pump body with one end of the ridge positioned directly under the inlet valve to eliminate the possibility of the valve becoming sealed in the closed position during the pumping operation. Additional longitudinal as well as transverse ridges can be provided in the base section as well as the interior of the pump dome to provide strength and rigidity within the pump body.  The pump body portion of the shunt is formed as a one-piece integral unit by means of injection molding.  Two separate mold core  are provided which are cantilevered with the pump body core supported by the vestibule core.  The vestibule core is in turn supported from the interior of the mold so as to hold both cores in proper position and alignment during the molding process. The inlet and outlet apertures for the proximal and distal catheters respectively, are sized according to the elasticity and tear-resistance of the materials used in the molding process so that the cores can be extracted from the article without tearing or otherwise injuring the pump body material.

Title: Bipmos decoder circuit
Inventor: HERNDON WILLIAM H
IPC: H03M7/00
Filed: 1988-04-26
Granted: 1992-02-11
Abstract: ABSTRACT OF THE DISCLOSURE A decoder incorporates the advantageous features of both bipolar and BICMOS decoding circuits through the use of BIPMOS technology.  PMOS gating transistors are used to control the operation of bipolar output transistors.  It is only necessary to operate the PMOS transistors with relatively small drain voltage variations, since the bipolar transistors are sensitive to such small variations.  Further, transient signals are referenced to one power supply voltage only, to thereby make the logic swing and performance characteristics of the decoder independent of power supply voltage variations.  Therefore it becomes possible to use PMOS transistors that have smaller voltage requirements than conventional CMOS circuits.

Abstract: OPTICAL COLLIMATING APPARATUS                ABSTRACT OF THE DISCLOSURE           An optical collimating apparatus employs a semi-reflective concave mirror and cholesteric liquid crystal element.  In one embodiment, the optical col-limating apparatus is used as a heads-up display device.          Images in the line of sight of an observer substantially pass through a transmitter/combiner, semi-reflective concave mirror, and cholesteric liquid crystal element to an observer.  Images generated by an image source are focussed on the transmitter/combiner such that the transmitter/combiner reflects the images into the line of sight of the observer.  The generated images are transmitted by the primarily transmissive (convex) side of the semi-reflective concave mirror to the cholesteric liquid crystal element.  The cholesteric liquid crystal element reflects the generated images back toward the primarily reflective (concave) side of the semi-reflective concave mirror, which in turn reflects the images back toward the cholesteric liquid crystal ele-ment, which transmits the generated images to the ob-server.  In an alternate embodiment, such as in a flight simulator or similar device, an image source projects images upon the primarily transmissive (convex) side of a semi-reflective concave mirror which transmits the images to a cholesteric liquid crystal element.  The images are reflected by the cholesteric liquid crystal element back toward the primarily reflective (concave) side of the semi-reflective concave mirror.  The images are then reflected by the semi-reflective concave mirror back toward the cholesteric liquid crystal element which transmits the images to the observer.
