Filed:

Aug 18, 1992

Appl. No.:

7/931750

Inventors:

Lawrence G. Clawson - Dover MA
Edward R. Cook - Northborough MA

Assignee:

Raytheon Company - Lexington MA

International Classification:

A21B 100

US Classification:

126 21A

Abstract:

A gas convection oven having a radiant burner and fuel feeding apparatus which enables the single burner to be operated in either a broil mode or a bake mode. In the broil mode, the radiant burner is operated in conventional manner with the flame being held by an inner screen to heat the outer screen to a radiant luminous temperature. In the bake mode, forced air is injected into the burner by a fan thereby providing a leaner fuel-air mixture with higher velocity. As a result, the flame burns outside the outer screen of the burner with the outer screen serving as a flame holder. Therefore, hot combustion gases as produced while the outer screen remains non-luminous.

International Classification:

G01N 33483

US Classification:

422 681

Abstract:

A method of immobilizing and stabilizing an active biological receptor in a polymeric film and receptor-based biosensors for determining an analyte of interest in a sample. The receptor-based biosensors include a polymeric film having a biological receptor capable of binding an analyte of interest immobilized therein according to the method of the present invention and an electrical means for determining the presence and quantity of the analyte. In particular, acetylcholine receptor and opiate receptor have been immobilized in a polymeric film made by combining the receptor, a material (e. g. , bovine serum albumin, gelatin) capable of polymerizing and a polymerizing agent (e. g. , glutaradehyde).

International Classification:

F16D 6602

US Classification:

188 1A

Abstract:

A system is provided for indicating excessive wear of brake linings. The system is usable on vehicles such as automobiles, cars, trucks and busses as well as aircraft or other applications where it is desirable to detect excessive wear of brake linings during operation thereof. The system includes an acoustical signal generating device having an air inlet normally closed by the brake lining. When the lining wears away to a minimum safe thickness, the inlet is opened and ambient air flows into the generator to produce an acoustical signal. An acoustical receiver is positioned in spaced operative relation to the brake system and responds to the acoustical signal to provide a warning indication on the dashboard, for example, of the vehicle so that the operator of the vehicle will be alerted to the worn brake condition.

US Classification:

435 4

Abstract:

An electrical biosensor for analyte determination is prepared by polymerization of a mixture of a biological receptor capable of binding an analyte in a sample, a protein and a polymerizing agent such as glutaraldehyde to form a polymeric film on a transducer. The mixture preferably contains a stabilizer selected from lipids, detergents and antioxidents. The receptor may be an acetylcholine receptor and the analyte, acetylcholine. A preferred stabilizer is a combination of phosphatidyl choline and octyphenoxypolyethoxyethanol. In carrying out a determination, analyte in a sample binds to the receptor causing a change in an electrical characteristic of the film which is indicative of the presence of the analyte. The biosensor may contain a second polymeric film that is free of the receptor and which serves as a control.
