Title: Track ball mounted on keyboard
Inventor: MARCHIS CARLOS
IPC: G06F3/038
Filed: 1992-04-03
Abstract: ABSTRACT OF THE DISCLOSURE                TRACK BALL MOUNTED ON KEYBOARD An improved track ball which can be conveniently manipulated with a single hand is disclosed.  The track ball protrudes through a circular opening in a housing, with the top edge of the housing having a rounded switch.  The switch can thus be manipulated with the fingers while the palm or thumb of the hand is manipulating the track ball.  The housing is mounted at an angle to the side of a computer keyboard, providing for easy access.  The track ball housing can be rotated to any continuous angle through two angles of rotation by the user.  A tetrahedron support arrangement holds the ball in place at any angle.  The same housing can be used for either the right or left sides of a keyboard by simply switching the activating point on the switch.  An encoder wheel is attached by a shaft to the ball and has a number of slots extending from its center to its edge.  The slots are rectangular in shape, and do not have edges along radial lines as in the prior art encoder wheels.

Title: Hot tip catheter assembly
Inventor: MALONE DAVID G
IPC: A61B18/08
Filed: 1990-08-24
Abstract: A hot tip catheter assembly (3) is disclosed which resolves atherosclerotic plaque buildup in vivo. The catheter has a heater (12), a cap (14), thermocouple, power leads (22a, 22b), thermocouple leads (20), and a central distal lumen (17) to position the catheter within the artery. The catheter tip has a thin, non-adhesive coating (25) of a hard, heat-conducting material. The thermocouple is used to continuously evaluate the temperature at the tip of the catheter, and the temperature is then regulated by a computer controlled feedback system. The catheter can completely melt the buildup without damage to the artery by direct contact with the plaque, without use of balloon catheter angioplasty.     Until further notice, any designation of "DE" in any international application whose international filing date is prior to October 3, 1990, shall have effect in the territory of the Federal Republic of Germany with the exception of the territory of the former German Democratic Republic.

Patent CA-2068198-A1 (CA)
Title: Articulating plate rotary engine
Inventor: RAMSEY JAMES E
IPC: F02B53/00
Filed: 1992-05-07
Abstract: ABSTRACT    An internal combustion articulating plate rotary engine is herein provided.  This rotary engine consists of a set of alternately rotating plates which provide alternate rotation to a set of ratchet disks.  The ratchet disks each drive one side  of  the  differential gear assembly which controls the output  shaft,  and  thereby  provide  and maintain constant power  and rotation to the output shaft.  Fuel injection and air intake occur in chambers defined by the rotating plates.          A   lock   down   pawl  mechanism  allows  two  simultaneous explosions  to  occur,  helps the compression, and defines a fixed  reference  point needed for widely varying speeds and loads.   Compression  is further enhanced by the feedback of inertia  from the output shaft to the plate ending its power stroke  and  beginning  compression.   The  lock  down  pawl mechanism  helps  to  fix  a  point  where  fuel  injection, compression,  and  combustion all coincide.  An anti-reverse mechanism  prevents the plate at the end of its power stroke from rotating clockwise during explosion as well as the next power stroke.

Filed: 1992-05-28
Abstract: LINEAR VISCOELASTIC AQUEOUS LIQUID AUTOMATIC DISHWASHER DETERGENT COMPOSITION               ABSTRACT OF THE DISCLOSURE      Automatic dishwasher detergent composition is formulated as a linear viscoelastic, pseudoplastic, gel-like aqueous product of exceptionally good physical stability, low bottle residue, low cup leakage, and improved cleaning performance, Linear viscoelasticity and pseudoplastic behavior is attributed by incorporation of cross-linked high molecular weight polyacrylic acid type thickener.  Potassium to sodium weight ratios of at least 1/2 minimize amount of undissolved solid particles to further contribute to stability and pourability.  Control of incorporated air bubbles functions to provide the product with a bulk density of  1.28 to 1.42 g/cc which roughly corresponds to the density of the liquid phase.          Stearic acid or other fatty acid or salt further improve physical stability.

Patent CA-2075625-A1 (CA)
Title: Enhanced capillary zone electrophoresis and apparatus for performance thereof
Inventor: BLANCHARD WILLIAM C
IPC: G01N27/447
Filed: 1991-02-07
Abstract: Capillary zone electrophoresis is enhanced by the application of an electric field across the interior of the capillary tube (10).  This external electric field is applied through a conductive member (104) at the exterior of the capillary tube (10). The external field vectorially couples with the internal field, controlling the polarity and the magnitude of the surface (zeta) potential on the interior surface of the capillary. The control of the surface (zeta) potential reduces adsorption of macromolecular onto the interior surface of the capillary tube, by inducing electrostatic repulsions between the macromolecules, and the capillary surface. Additionally, the control of the surface (zeta) potential can retard, and even reverse, electroosmotic flow, depending upon the magnitude of those fields.

Abstract: SUPERALLOY COMPONENT WITH DISPERSION-CONTAINING       PROTECTIVE COATING, AND METHOD OF PREPARATION                 ABSTRACT OF THE DISCLOSURE     A coated superalloy component includes a substrate article formed of a superalloy and an adherent coating over the substrate.  The coating is a nickel-base superalloy containing at least about 0.3 volume percent or more of a dispersed oxide of yttrium, hafnium and/or a rare earth, and, preferably, grain boundary strengthening elements such as carbon, zirconium, and boron.  The oxide dispersoids improve the performance of the coating in service, reducing the incidence failures due to thermal fatigue, oxidation, and corrosion damage.  The dispersoid-containing coating may be formed by directly depositing the oxide-containing coating, or by depositing a metallic coating and then forming the dispersoids by subsequent heat treatment.

IPC: H01S5/00
Filed: 1991-05-06
Abstract: A monolithically integrated structure comprises a laser diode (60), a photodetector diode (62) and a reference diode (64) which are monolithically integrated on a common substrate (10). The photodetector diode (62) is optically coupled to the laser diode (60).  The reference diode (64) is substantially identical to the photodetector diode (62) and optically decoupled from the laser diode (60). When substantially equal reverse biases are applied to the photodetector diode (62) and the reference diode (64), the reference diode (64) conducts a leakage current which can be used to substantially cancel the leakage current of the photodetector diode (62). The monolithically integrated structure may also include a modulator diode (100) which is monolithically integrated on the common substrate (10) and optically coupled to the laser diode (60). The monolithically integrated structure is useful in optical communications systems.

Title: A detection system for use in an aircraft
Inventor: BARTON IAN JAMES
IPC: B64D45/00
Filed: 1991-04-09
Abstract: A detection system for use in an aircraft which is able to monitor atmospheric conditions ahead of the aircraft, generate an alarm signal if adverse atmospheric conditions exist ahead of the aircraft and generate information which indicates the posi-tion of the adverse conditions so the adverse conditions can be avoided. The system is able to detect the presence of volcanic ash cloud ahead of the aircraft and, if desired, can also be used to detect a high density of sulphur dioxide gas and/or clear air turbulence ahead of the aircraft. The system monitors infrared radiation received by the aircraft, generates intensity signals re-presentative of at least one predetermined wavelength of the ra-diation and compares intensity signals with reference signals or intensity signals of another infrared wavelength. If the results of the comparison which indicate the adverse conditions are pres-ent, an adverse condition warning signal is generated and the de-vice is also able to generate video display signals for producing a video display which indicates the position of the adverse condi-tions relative to the aircraft.
