US Patent:

45028478, Mar 5, 1985

Filed:

Sep 29, 1982

Appl. No.:

6/427651

Inventors:

Donald J. Pozniak - Utica MI
Gerald F. Robertson - Mt. Clemens MI
Michael J. McClain - Dayton OH

Assignee:

General Motors Corporation - Detroit MI

International Classification:

F04B 3500
F04B 3900

US Classification:

417380

Abstract:

A vacuum pump assembly which is driven by pulsating exhaust gases emanating from an internal combustion engine is disclosed. The pump assembly includes a staged pump means for pumping air from a vacuum source and having a reciprocable pumping member, an actuating means including a reciprocable actuating member drivingly connected to the pumping member and which is driven through first and second strokes to move the pumping member through first and second strokes, respectively, one side of the actuating member being in communication with the exhaust gases and with the actuating and pumping members being movable through their first strokes during the pressure increasing phase of each pressure pulsation and being moved through their second strokes by a nonlinear variable rate spring means during each pressure decreasing phase of each pressure pulsation whereby the pump assembly is operable to pump air from the vacuum source throughout a wide range of engine speeds and loads including high speeds and loads.

Abstract:

A vacuum pump assembly which is driven by pulsating exhaust gases emanating from an internal combustion engine is disclosed. The pump assembly includes a double-acting pump means for pumping air from a vacuum source and having a reciprocable pumping member, an actuating means including a reciprocable actuating member drivingly connected to the pumping member and which is driven through first and second strokes to move the pumping member through first and second strokes, respectively, one side of the actuating member being in communication with the exhaust gases and with the actuating and pumping members being movable through their first strokes during the pressure increasing phase of each pressure pulsation and being moved through their second strokes by a first nonlinear variable rate spring means during each pressure decreasing phase of each pressure pulsation during low to intermediate engine speeds and loads and by both the first and a second nonlinear variable rate spring means during intermediate to high engine speeds and loads whereby the pump assembly is operable to pump air from the vacuum source throughout a wide range of engine speeds and loads including high speeds and loads.

Appl. No.:

16/567230

Inventors:

- Oak Park MI, US
Michael S. McClain - Waterford MI, US

Assignee:

MP ACQUISITION, LLC - Oak Park MI

International Classification:

A61G 13/00
A61G 13/10

Abstract:

An anatomy table for use in autopsies and dissections comprises a base and an immersion storage tank arranged in the base. The anatomy table further comprises a dissection lid arranged on the base, wherein the dissection lid covers the immersion storage tank in its closed position. The table also comprises a hinge secured between the dissection lid and a top edge of the base, wherein the dissection lid rotates about the hinge between a first and second position, wherein the first position allows for access to the body stored in the anatomy table immersion storage tank while the second or closed position of the dissection lid allows for dissecting to occur directly on top of the anatomy table. This may allow for a two in one table to be arranged within a lab, such that autopsy work and dissection or cutting may be performed with the same piece of equipment, wherein two pieces of equipment are usually used within the lab for these procedures.

Abstract:

A grossing station comprising a table and a hood connected to the table. The grossing station also comprises a quick release camera system secured to a surface of the hood, wherein the quick release camera system is detachable from the hood for close up angles and zoomed location still or video images of the body or material being examined on a surface of the grossing station.

A61B 16/00

Abstract:

A grossing station for use in autopsy, necropsy, dissection, and laboratory work comprises a table and a hood connected to the table. The grossing station also comprises an integrated gas sensor system having at least one gas sensor, wherein the integrated gas sensor system is secured to a bottom surface of the hood. The integrated gas sensor system provides real time sampling and reporting of a predetermined noxious gas within a work area of the grossing station. The grossing station may also include a second gas sensor used in conjunction with the first gas sensor to allow for more accurate detection and reporting of over exposure events to a user of the grossing station.
