Title: Dc chopper circuit fed by a constant current source
Inventor: MURISON GEORGE E
IPC: H03K17/04
Filed: 1986-04-11
Granted: 1990-12-27
Abstract: DC CHOPPER CIRCUIT FED BY A              CONSTANT CURRENT SOURCE               Abstract of the Disclosure An apparatus for periodically interrupting a large direct current flow through a load is able to maintain a substantially constant level of current from the source both when it flows through the load and when it is interrupted, with minimum effect on the direct current source.  A first power semiconductor switch is connected in parallel with the load and is switched on briefly to transfer current flow from the load to the first semiconductor switch.  A second power semiconductor switch is in series with a precharged capacitor across the load.  When the second power semiconductor switch is gated on a large influx of current through the second semiconductor switch into the capacitor transfers the current flow from the first semiconductor switch to the second semiconductor switch   When the charge on the capacitor reaches a level sufficient to turn off the second semiconductor switch, the current flow transfers back to the load.          Any minor fluctuations in current level during the transfers are smoothed by an inductor in series with the output from the direct current source.

Inventor: MCCANTS MALCOLM T
IPC: C10G65/12
Filed: 1988-06-14
Granted: 1992-02-11
Abstract: ABSTRACT OF THE DISCLOSURE        Crude oils are normally so viscous that they cannot be pumped through pipelines without periodic heating.  The usual practice is to pump the oil from one heat station to another, with part of the crude oil being used to generate heat.  This problem is solved by reducing the viscosity of the crude oil.          The viscosity reduction is effected using reactors for partially cracking crude oil, mixing the partially cracked oil with in-coming crude oil, separating gases from the liquid in the mixture in a flash vessel, condensing the gases to yield liquid hydro-carbons, and mixing the latter with untreated crude oil and liquid residue from the flash vessel to yield a flowable, relatively low viscosity mixture. Coke produced in the reactors is periodically reacted with superheated steam to yield hydrogen, which is used to improve the quality of some of the residue from the flash residue.  The thus treated flash vessel residue is used to feed the reactors.

Title: Overload protection for d.c. circuits
Inventor: KRUSE JAMES W
IPC: B60Q1/44
Filed: 1988-08-05
Granted: 1992-05-12
Abstract: OVERLOAD PROTECTION FOR D.C. CIRCUITS                     ABSTRACT OF THE DISCLOSURE         Protection for D.C. electrical circuit branches against incipient overloads comprises the use of semiconductor devices known as intelligent switches.  An intelligent switch comprises a main controlled conduction path whose conductivity is controlled by an external control input.  The semiconductor architecture is configured to possess internal self-protection for the main controlled conduction path against incipient current and/or temperature rises exceeding the device's rating by rendering the main controlled conduction path non-conductive when such incipient conditions are sensed.  The invention, recognizing that this internal self-protection attribute can be used also to provide protection for external circuit components connected to the switch in the branch, further comprises the elimination of external protective devices from the branch such that the intelligent switch itself provides the entire overload protection within the branch.  The invention is especially beneficial in automotive electrical application, imparting improvements to particular specific circuits of automotive electrical systems.

Granted: 1991-11-26
Abstract: Abstract Apparatus for projecting multiple images from a pair of reticles (117) to a photo-sensitive coated substrate (1) to produce large scale electronic devices (2).  A pair of parallel and proximate optical systems (29) are used, the optical systems being positioned to project in the z-direc-tion upon a movable stage (11) subject to controlled motion (159, 169) in the x- and y-directions.  The apparatus in-cludes means (225) for determining the coordinates of motion of the stage relative to images projected from the reticles, means for using the determined positions to establish a stage transfer function for the apparatus relative to various positions of stage, and means (130) for applying the transfer function to adjust the relative positions of the reticles (117) and substrate (1) for accurate image projection, and for thereafter projecting an image upon the substrate.  The stage is then stepped to a position to permit projection of an abutting image, and the transfer function is used to adjust the relative positions of the reticles (117) and sub-strate (1) for accurate image projection for projecting the abutting image upon the substrate (1).  The steps are re-peated until sufficient images have been projected upon the substrate to make up one integrated layer of a flat panel display or other large scale electronic device.  After treat-ing the photosensitive layer, subsequent layers are produced in a similar manner.
