Inventor: GLUCINA ANTHONY PHILIP
IPC: H02P6/24
Filed: 1991-12-18
Granted: 2001-02-27
Abstract: A method of braking an electronically commutated motor (ECM) by connecting a braking resistor across the motor supply rails and controlling the commutation sequences of the motor.

Title: Bleed alleviation using zwitterionic surfactants and cationic dyes
Inventor: MOFFATT JOHN R
IPC: C09D11/00
Filed: 1992-01-13
Granted: 2002-07-02
Abstract: Color bleed (the invasion of one color into another on the surface of the print medium) using ink-jet inks is al-leviated by employing zwitterionic surfactants (ph-sensi-tive or pH-insensitive) or ionic or non-ionic amphiphiles.      The inks of the invention comprise a vehicle and a cationic dye. The vehicle typically comprises a low viscosity, high boiling point solvent, one or two amphiphiles at concentra-tions above their critical micelle concentration (cmc), while the dye typically comprises any of the dyes commonly employed in ink-jet printing. The amount of surfactant/-amphiphile is described in terms of its critical micelle concentration (cmc), which is a unique value for each am-phiphile. Above the cmc, micelles form, which attract the dye molecule and thus control the color bleed. Below the cmc, there is no micelle formation, and thus no control of the color bleed.

Title: Rolling element cage constraint
Inventor: MCCARTHY DONALD J
IPC: F16C29/04
Filed: 1992-06-11
Granted: 1998-11-24
Abstract: An improved linear bearing assembly comprising sets of guides (ways) for guiding rolling elements (ball bearings or rollers) constrained within a cage. Typically, two sets of rolling elements and cages are used between a moving part and a stationary part. Each set has four resilient elements (springs) with one end of each spring anchored to the cage and with the other ends of two springs anchored to the stationary way or part and the other ends of the other two springs are anchored to the movable way or part.  This arrangement provides a restoring spring force that gradually forces the cage to its correct tracking position.  If the cage is tracking properly, the spring forces cancel out and there is no inherent rubbing in the restoring mechanism.

Title: Two-frequency transmitting apparatus with tone-modulation phasing for an instrument landing system
Inventor: GREVING GERHARD
IPC: G01S1/14
Filed: 1993-02-15
Granted: 2003-09-09
Abstract: Two-frequency transmitting apparatus (S1, S2, LA) for instrument-landing systems is disclosed which is in-sensitive to so-called DDM distortions caused by re-flections of the clearance signal from obstacles (H) located near the runway (RW). This insensitivity is achieved by different phase shifts of the equal modu-lation frequency (90 Hz and 150 Hz) used for the course and clearance signals. The different phase shifts cor-respond to a phase shift of a common fundamental fre-quency (30 Hz). The two-frequency transmitting apparatus can be used to specify a localizer course or a glide path.

Title: Contact-type image sensor for generating electric signals corresponding to an image formed on a document
Inventor: TANIMIZU HIROMI
IPC: H04N1/031

Granted: 1999-03-23
Abstract: Light-shielding layers are adhered to the lower surface of a glass plate, spaced apart from each other and defining a slit having a width of L.  An array of rod lenses is located below the glass plate, such that the optical axes of the lenses pass through the slit. The lower surface of the glass plate is generally covered, and exposed via the slit only.  Hence, the leakage of lights reflected from points near a reading position into each photoelectric conversion element is minimized, whereby the element outputs a pixel signal faithfully representing that part of the image which is located at the reading position.

Abstract: Aromatic byproducts normally formed in the dehydrogenation of normal paraffins to linear monoolefins have been found to be are detrimental in the usual processes of aromatic alkylation using the dehydrogenation product mixture as an alkylation feedstock. In particular, when solids are used as the alkylation catalysts with recycle of the unreacted feedstock to the dehydrogenation reactor the aromatic byproducts increase to a level where they exert a significant decrease in the stability of the alkylation catalyst. When the aromatic byproducts are removed in whole or in part alkylation may be performed at a substantially lower temperature, which affords alkylated aromatics whose alkyl portion has greater linearity than that observed at a higher alkylation temperature.

Abstract: Pulse frequency modulation is used to control brakes and clutches 10 which are operated by fluid pressure actuators 22 controlled by electrically actuated solenoid valves 28. Short pulse periods for all duty cycles are generated by feedback from the solenoid valve 28 or from the actuator 22. In one circuit an electrical control 30 triggers a flip-flop 38 which starts solenoid current.      Solenoid movement results in back-emf and its effects on the solenoid flux field or current is detected and used as a feedback signal to reset the flip-flop 38 to thereby turn off the current as soon as the valve 28 is operated. In another circuit, a computer control 30' emits a command for a certain pulse period. Actuator pressure or position is monitored to produce a feedback signal to the computer. If the signal is not received, the pulse period is increased for the next pulse command so that a sufficient pulse period will be found. If the magnitude of the actuator response exceeds a threshold, the pulse period is decreased for the next pulse command. Pulse width modulation may also be improved by the same technique for minimizing the pulse period at the lowest duty cycles and yet assuring actuation.

Title: Three dimensional seismic data acquisition using a repeating offset arrangement of source and receiver lines
Inventor: CORDSEN ANDREAS
IPC: G01V1/04
Filed: 1994-08-19
Granted: 1998-05-19
Abstract: The invention involves providing a plurality of substantially parallel and equally spaced source lines, each of which are formed by a plurality of equally spaced seismic energy sources. A plurality of substantially parallel and equally spaced receiver lines are also provided, each formed by a plurality of equally spaced seismic energy receivers. The source and receiver lines are overlaid in a transverse crossing manner, forming a rectangular grid, so that the spacing or relative offset between source and receiver is repeated only at every second or greater number of crossings. Preferably, the relative offset is substantially zero so that a source and a receiver are substantially coincident at only every second or greater number of crossings. For each seismic disturbance, an array of common mid-point ("CMP") seismic reflections is produced. Each CMP forms the center of one of multiple sub-bins which together form a standard bin. Stated otherwise, by slightly varying the source, receiver and line intervals so that the relative offset between a receiver and a source is repeated, but only at every second or greater crossing, the number of CMP's per bin has been multiplied. During processing of the seismic survey results, adjacent sub-bins can be incrementally combined or trimmed to adjust the standard bin to a larger or smaller size, thereby permitting an explorationist to optimize between increased fold or more detailed resolution respectively.
