US Patent:

55806341, Dec 3, 1996

Filed:

Sep 26, 1994

Appl. No.:

8/312469

Inventors:

George M. Stout - Maplewood MN
James G. Homan - Eagan MN
John R. Mlinar - Coon Rapids MN
Larry R. Wright - Ames IA

Assignee:

Minnesota Mining and Manufacturing Company - St. Paul MN

International Classification:

B24D 1100

US Classification:

428 659

Abstract:

The present invention provides a backing for a coated abrasive article, wherein the backing includes a tough, heat resistant, thermoplastic binder material, and an effective amount of a fibrous reinforcing material distributed throughout the thermoplastic binder material. The tough, heat resistant, thermoplastic binder material and the fibrous reinforcing material together form a hardened composition that will not substantially deform or disintegrate during use.

US Patent:

40538435, Oct 11, 1977

Filed:

Mar 25, 1976

Appl. No.:

5/670217

Inventors:

Larry Richard Wright - Glenview IL
Donald Charles Cohlman - Rolling Meadows IL

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

H04B 110

US Classification:

325479

Abstract:

A radio receiver includes a blanker circuit for muting the receiver in response to interfering noise signals. The invention contemplates a transistor switch which, when biased to its nonconducting state, inhibits blanker action. The transistor is biased to nonconduction when the receiver provided automatic gain control (AGC) level is below the threshold voltage of the transistor. An adjustment is provided for controlling the AGC level at which blanker inhibit is introduced. Temperature compensating circuitry maintains inhibit action response at the threshold voltage with changes in ambient temperature.

US Patent:

Filed:

Feb 6, 1978

Appl. No.:

5/875977

Inventors:

James W. Rae - Schaumburg IL
Larry R. Wright - Glenview IL

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

H04B 110

US Classification:

455311

Abstract:

A balanced, doubly tuned gate couples between the mixer and intermediate frequency (IF) stages of a conventional radio receiver. The network is comprised of a pair of matched transformers interconnected in a balanced configuration, with the first transformer tuned to the mixer and the remaining transformer tuned to the IF stage. Capacitors interconnect the two transformers resulting in a Butterworth filter network. Two diode pairs connect in shunt across selected windings of the transformers. Direct current bias normally biases the diodes to a nonconducting state, thereby allowing the mixer signals to pass to the IF stage. A blanking signal from the receiver blanker drives the diodes to conduction thereby decoupling the mixer from the IF and blanking the receiver. Due to the doubly balanced nature of the gate, blanking is accomplished with a minimum of switching time. Moreover, the shunt diode switching scheme provides superior attenuation in the blanking mode and enhanced operation in the normal mode.
