Title: Flowmeter for providing synchronized flow data and respiratory gas samples to a medical mass spectrometer
Inventor: HALL LAWRENCE G
IPC: H01J49/24

Granted: 1982-10-12
Abstract: ABSTRACT OF THE DISCLOSURE    Respiratory gas flow data is synchronously provided along with continuous samples of the gases for analysis by a medical mass spectrometer.  The gas flow data is determined by use of the differential pressure across a resistive core in a sampling flowmeter and the flow value at any instant is registered by proportionately admitting a non-toxic gas that is foreign to the normal respiratory gases into the sampling inlet in a quantity controlled by the differential pressure.          The quantity of foreign gas therefore represents flow and is drawn through the inlet tube in exact synchronism with its corresponding respiratory gas sample for analysis by the spectrometer.  The generated signal representing the amount of foreign gas, hence the flow, may then be used with the signals representing concentration of the various gases in the corresponding respiratory gas sample to calculate various medical parameters, such as oxygen uptake, where the exact synchronism of these signals is important.

Abstract: ABSTRACT OF THE DISCLOSURE     This disclosure deals with a drive for a fan of an internal combustion engine, the drive including a clutch connected between the engine and the fan blades.  A piston is movable to actuate the clutch, and an actuating fluid is employed to move the piston.  The fan drive is connected to the engine lubricating system so that the engine lubricant acts as the actuating fluid.  An engine temperature respon-sive circuit actuates the clutch to engage and disengage at certain engine temperatures.  The fan drive includes a fluid feed path, return path and control path, but only two fluid connections to the clutch are necessary.  When the tempera-ture responsive circuit operates to disengage the clutch, a valve releases the pressure in order to quickly disengage the clutch.

Abstract: HYDROSTATIC STEERING CONTROLLER       WITH PRESSURE DAMS                     ABSTRACT OF THE DISCLOSURE    A hydrostatic steering controller including a pair of valve members which are relatively movable in opposite directions from a neutral position to a pair of operating positions to control flow between a fluid pressure source and a hydraulic steering motor.  In each of the operating positions the valve members include interfacing surfaces which define part of a first passage directing high pressure fluid to the steering motor and a second passage directing low pressure fluid from the steering motor to a reservoir   The interfacing surfaces of the valve members create a pressure dam between the first and second passages when the valve members are relatively moved by a predetermined amount away from the neutral position and to an operating position.   The pressure dam minimizes leakage between the first and second passages.  The pressure dam is created in a pressure dam groove formed in a surface of one of the valve members.  The pressure dam groove is connected with the fluid pressure source, and is disposed in facing relationship with a low pressure return groove formed in a surface in the other valve member when the valve members are in their neutral position. when the valve members move to their operating position a surface on the other valve member moves into facing relation with the pressure dam groove, thus increasing the pressure in the pressure dam groove.

Abstract: ABSTRACT OF DISCLOSURE   This specification discloses certain improvements in resealable pressure releasing closures of the type disclosed in U.S. Patents 4,105,134 and 4,155,480 Debenham et al.  In the several improvements disclosed in the specification, the resealing properties of the closure are improved by reducing the concentration of the flexure of the closure at the connection between the closure and the can end to thereby reduce the extent to which the material defining the connection permanently deforms during the opening operation.  In one embodiment the pressure releasing closure or tab 20 has a connection 23 to the can end which is at substantially the same level as the adjacent portion of the closure by the provision of an area 26 immediately behind the connection which is downwardly depressed so as to be co-planar with the tab 20.  In another embodiment the upwardly raised bead 31 extends from the connection 32 into the closure 30 to substantially stiffen the connection 32 and discourage bending of the sheet metal at the connection 32.  Other embodiments involve the cold reduction of the pressure releasing closure and the shape of the closure to make the bending thereof more uniform during the opening operation.
