International Classification:

C09J 163/00

US Classification:

156330, 523428

Abstract:

Epoxy resin compositions contain (i) a polyepoxide resin; (ii) a benzofuran diol component, a benzofuran di-epoxide component, or mixture thereof; and (iii) a curing agent, which upon curing, provides a cured resin exhibiting improved chemical and physical characteristics. The epoxy resin composition may also contain a toughening agent to further enhance the cured resin's physical characteristics.

US Patent:

53509889, Sep 27, 1994

Filed:

Jul 2, 1991

Appl. No.:

7/724647

Inventors:

Dong T. Le - Lakewood CA

Assignee:

AlliedSignal, Inc. - Morris Township, Morris County NJ

International Classification:

H02P 540
H02P 800

US Classification:

318618

Abstract:

A digital motor controller employs a digital signal processor to generate commutation commands that drive and brake a motor. The commutation commands are pulse width modulated. To avoid shoot-through, the digital signal processor automatically adjusts the widths of the pulses according to the amount of current being drawn by the motor. Motor speed is measured by taking the difference between consecutive samples from a position sensor and dividing the difference by the sampling time. The digital signal processor also closes position, speed and current loops. The commands provided by each loop are limited between upper and lower limits. Further, the digital signal processor automatically adjusts the upper and lower limits to compensate for changes in design characteristics due to variations in temperature. The digital motor controller can be used to control different motors having different design characteristics simply by reprogramming the upper and lower limits. A plurality of digital motor controllers can be used to control motors operating in tandem.

Filed:

Nov 7, 1994

Appl. No.:

8/335026

Inventors:

Dong Tuan Le - Lakewood CA
Colin E. Huggett - Torrance CA

Assignee:

AlliedSignal Inc. - Morris Township NJ

International Classification:

G05B 902

US Classification:

318564

Abstract:

A fault tolerant controller arrangement for electric motor driven apparatus is implemented by a plurality of control channels, each of which includes a motor and associated drive circuitry. The implementation is such that the rating of each of the plurality of channels is reduced and all channels are operated such that the load is shared between all operating channels. The arrangement is such that all channels share the load dynamically and statically and that each channel in a system of n channels supplies. sup. 1 n of the required load driving force in the same direction.

Jul 9, 1991

Appl. No.:

7/727516

Inventors:

Roger P. Murry - Los Angeles CA
Dong T. Le - Los Angeles CA

Assignee:

Allied-Signal Inc. - Morris Township, Morris County NJ

International Classification:

H02P 500

US Classification:

310 68B

Abstract:

A solid state controller is mounted directly to a permanent magnet, brushless DC motor. The controller operates the motor at constant torque and variable speed. Speed is determined in accordance with density of the through flow. The motor and controller can be employed to circulate fluid in a circulation loop having variable pressure.
