International Classification:

G01N001/10

US Classification:

356246

Abstract:

Luminescence test measurements are conducted using an assay module having integrated electrodes with a reader apparatus adapted to receive assay modules, induce luminescence, preferably electrode induced luminescence, in the wells or assay regions of the assay modules and measure the induced luminescence.

Appl. No.:

11/152017

Inventors:

Tejinder Singh - Canton MI, US
Kent Johnson - Ypsilanti MI, US

Assignee:

General Motors Corporation - Detroit MI

International Classification:

F16H 57/04

US Classification:

475160

Abstract:

A differential lubrication system includes structure forming a torque converter feed passage in fluid communication with a fluid source and in which fluid is selectively supplied to a torque converter. Structure forming a branch passage for lubricating a differential mechanism extends from the torque converter feed passage to divert fluid to the differential mechanism prior to the fluid being supplied to the torque converter. Two flow restrictions and a valve mechanism may be employed to control lubrication of the differential mechanism. One of the flow restrictions may form a nozzle so that fluid is sprayed onto the differential mechanism. A method of lubricating the differential mechanism is also provided.

General Motors Corporation - Detroit MI

International Classification:

F04B 23/04
F04B 23/08
F04B 23/00
F04B 49/00

US Classification:

417 79, 417 87, 417307, 417313, 210307, 210440

Abstract:

The filter housing has a filter outlet portion with a central filter outlet passage. The outlet portion includes a terminal end portion defining a filter nozzle. The filter nozzle forms a nozzle passage between the filter nozzle and the pump housing. The nozzle passage communicates with an annular recess formed in the filter outlet portion. The annular recess receives return bypassed hydraulic fluid from a regulator valve for distribution into an inlet stream of fluid flowing through the filter outlet passage. The inlet stream velocity is increased which increases the pressure at the pump inlet. The increased pressure at the pump inlet allows the pump to operate at higher speeds without cavitation.

B01D 35/02

US Classification:

210232, 2103231, 21016708, 2104165

Abstract:

A method and apparatus for a compact dual transmission filter design is provided. More precisely, a single filter housing is adapted to accommodate a primary filter and an auxiliary filter in fluid communication with a primary pump and auxiliary pump, respectively. The single filter housing having two filters disposed therein is more compact than a conventional design incorporating a separate filter housing for each filter.

Assignee:

General Motors Corporation - Detroit MI

International Classification:

F04B 23/00

US Classification:

417313, 4174239

Abstract:

A filter and pump include complementary engagement features such that the filter is inserted into the pump and thereafter rotated approximately 90 degrees to engage a twistlock feature. In this manner, filter attachment is maintained without additional fasteners, spring clips, clamping plates, etc.

Assignee:

GM Global Technology Operations, Inc. - Detroit MI

International Classification:

F04B 41/06

US Classification:

417 2, 41742314, 184 63

Abstract:

The apparatus of the present invention provides a compact dual-pump assembly for an automotive transmission. The dual-pump assembly preferably includes a housing having a valve assembly mounted thereto. The valve assembly includes a shuttle valve disposed in fluid communication with a pressure regulating valve. An on-axis pump is mounted to the housing in fluid communication with the shuttle valve and the pressure regulating valve. An off-axis pump in fluid communication with the shuttle valve is mounted to the housing in close proximity to the on-axis pump such that the dual-pump assembly is compact.
