Filed:

Aug 31, 1999

Appl. No.:

09/387543

Inventors:

Giles J. Brereton - Williamston MI
Harold J. Schock - Okemos MI
Ruby N. Ghosh - Okemos MI

International Classification:

G01N 324

US Classification:

73841, 7386174

Abstract:

The present invention relates to a sensor for measuring the instantaneous rate of mass flow and the cumulative mass flow in steady or unsteady flows of single-phase liquids or gases in a duct. By measuring the shear stress or the streamwise pressure gradient at the duct wall, and relating it to mass flow through solutions to the Navier Stokes equations of fluid mechanics, information on mass flow through the entire duct cross sectional area is deduced.

International Classification:

F02M 2708

US Classification:

123537

Abstract:

The performance of an internal combustion engine is optimized utilizing an electrically controlled driver which is located relative to the intake port to excite the intake charge at a selected frequency, duration and power level which depends on the engine operating condition. The purpose of this excitation is to control combustion by optimizing large scale recirculation patterns of the intake charge within the combustion chamber. In particular, this device will provide the effect of optimizing volumetric efficiency at wide open throttle and minimize fuel consumption and emissions at part throttle. An electronic engine controller varies the operation of the drive device as a function of engine operating conditions. The driver excites the intake charge at a frequency of about 5 to 1000 times of the engine speed.

Inventors:

Harold J. Schock - Okemos MI
Thomas R. Stuecken - Grand Ledge MI

International Classification:

B07C 900

US Classification:

209700

Abstract:

An apparatus (10) and method for removing hulls (152) from a nut mixture (150) is described. The apparatus includes a gravity feed bin (12), a conveyor (28) and removal units (38). The removal units include a drum (40), a position roller (50), a beater (56) and a brush (64) around all of which extends a fibrous mat (96). The fibrous mat has looped or curved fibers (96C) and is formed as a continuous belt in the removal unit. The removal unit also includes a deflector (92) and a shield (93) to guide the removed hulls into an auger (78) to be removed from the apparatus. To operate the apparatus, the mixture is fed from the gravity feed bin onto the conveyor belt (30) of the conveyor. As the mixture moves along a horizontal path of the conveyor, the mixture comes in contact with the fibrous mat rotating in the removal units. The looped fibers of the mat contact and engage the projections (152A) on the outer surface of the hulls and secure the hulls to the mat.

International Classification:

F02B 19/12
F02M 61/14
F02B 19/18

Abstract:

An internal combustion engine includes multiple fuel injections external to a pre-chamber. A further aspect provides an engine pre-chamber ignition apparatus which employs a pre-assembled and/or removable cartridge including an ignitor and a fresh air inlet but not a fuel inlet injector directly mounted thereto. Another aspect of a vehicular engine apparatus includes a fuel injector positioned externally to a pre-chamber which delivers an initial greater quantity of fuel for combustion and then a later and smaller quantity of fuel for pre-chamber ignition.

Abstract:

A thermoelectric device () and a method for manufacturing and using the same are disclosed. The thermoelectric device () includes a hot shoe () and a cold shoe () disposed about the hot shoe. A heat conducting member () formed of a thermoelectric material extends between the hot shoe () and the cold shoe () and generates electricity in response to a temperature difference therebetween. The hot shoe () is heated and expands at a greater rate than the cold shoe () does during operation. The structural and spatial relationship of the hot shoe () and the cold shoe () maintains the thermoelectric material of the heat conducting member () in compression during operation of the thermoelectric device ().
