40922642, May 30, 1978

Filed:

Dec 27, 1976

Appl. No.:

5/754466

Inventors:

Peter Hing-Shya Tsang - Southfield MI
Richard W. Hradek - Royal Oak MI
James Daniel Bode - Davenport IA

Assignee:

The Bendix Corporation - South Bend IN

International Classification:

A61L 1300

US Classification:

252186

Abstract:

A process of manufacturing an oxide material for use in an oxygen generator. A quantity of dry zirconia particles is blended with Barium Peroxide particles and thereafter heated in a nitrogen atmosphere until the Barium Peroxide melts and coats the zirconia particles. The Barium Peroxide coating is subsequently decomposed to Barium Oxide. The Barium Oxide coated zirconia particles are allowed to cool and then passed through a grinder to produce a uniform particle size for oxide material.

International Classification:

F16D 6900

US Classification:

188251M

Abstract:

Friction material pads for use in a brake system with an aluminum-metal matrix composite rotor wherein a brake application can create operational temperatures that approach 450C. The formulation of the composition for the friction pads is generically a basic non-asbestos organic formula modified to include a high abrasive content, solid lubricant package, and a porous copper powder. The porous copper powder which makes up from 2-18 percent by weight the friction pads has a nominal diameter of 0. 20 mm. The porous copper powder proportionally responds to temperature and mechanical forces generated during a brake application by deforming and smearing to aid in the formation of a glaze between the engaging surfaces of the friction pads and aluminum-metal matrix composite rotor. This glaze prevents scoring of the aluminum-based rotor while at the same time maintaining a substantial stable coefficient of friction of approximately 0. 4 during brake applications over a wide range of speeds and deceleration rates.

D04H 164

US Classification:

4283084

Abstract:

A method of manufacturing a friction article wherein a fiber material (14) having a continuous and substantially uniform three dimensional matrix which is filled with a slurry (24) made up of fillers, friction modifiers, a reinforcing material and a liquid binder. The filled fiber material is conveyed to a dryer (32) where the volatile solution is evaporated leaving the fillers, friction modifiers, reinforcing material and binder. The filled fiber material (14) is thereafter placed in an oven (50) where a compressive force is applied thereto while the binder is cured to define a second matrix which holds the fillers, friction modifiers, and reinforcing material in the three dimensional matrix.

Yiren S. Wang - Sidney OH

Assignee:

Allied-Signal Inc. - Morristown NJ

International Classification:

B60T 858

US Classification:

303100

Abstract:

A noise sensor for supplying a central processing unit of an anti-lock brake system with a noise signal corresponding to vibrations produced during braking. The central processing unit responds to the noise signal by supplying a control valve assembly with an operational signal which modulates the fluid pressure supplied to a wheel cylinder to create a predetermined fluid pressure frequency therein to nullify vibrations and correspondingly attenuate noise produced thereby.

International Classification:

F02D 1900

US Classification:

123 25A

Abstract:

In a vehicle having a turbocharger (12) for supplying pressurized air to a combustion chamber in an engine (10) and a storage reservoir (34) for supplying pressurized air as a power source for a brake system (35), a polymeric fiber membrane (46) for separating pressurized air from a compressor (18) into moist oxygen enriched air and dry nitrogen enriched air. The moist oxygen enriched air is added to inlet air of the turbocharger (12) to enhance combustion of fuel in the combustion chamber while the dry nitrogen enriched air is communicated to the storage reservoir (34) to operate the brake system (35) and reduce the possibility of oxidization of components therein.
