A combined temperature and pressure sensing probe assembly for a flow measurement system comprising a body, a portion of which is adapted for insertion into fluid flowing in a confined conduit, such as a pipe. Within the body are separated plenums which are exposed respectively to high and low fluid pressures in the fl...
A hemolyzing tube (A) having its interior (10) evacuated and containing a standard amount of a blood dissolving liquid (3) has a tubular body (2) whose closed bottom faces a top mouth closed with a stopper (1) capable of being pierced. The tube is usable with a cylindrical casing (C) having a double-ended needle (8) an...
A matrix of heat exchange tubes in a heat exchanger in which a first fluid flows in the heat exchange tubes and undergoes heat exchange with a second fluid flowing externally on the heat exchange tubes. The tubes have a teardrop shape and are arranged in the matrix in parallel relation in rows in which each tube has a ...
An arbitrary voltage distribution can be achieved in a high-voltage generator which supplied an X-ray tube having a metallic central part, wherein the anode voltage and the cathode voltage are generated in the high-voltage generator by two series-connected high-voltage rectifiers with respective preceding high-voltage ...
A device for air flow rate measurement in the air intake tube of an internal combustion engine which has at least two temperature-dependent resistors in different branches of a bridge circuit having closed-loop electric current control, and which is characterized in that the temperature-dependent resistors are embodied...
A guide and a method of using the guide to install a spline of a canopy in a channel formed in a side wall of a roller tube having an end with a circumferential edge. The guide has an interior groove formed therein for receiving a portion of the circumferential edge so as to mount the guide to the roller tube. A wall o...
In a blow-off device for limiting excess pressure in nuclear power plants, a condensation tube disposed so that a lower outlet end thereof is immersed in a volume of water in a condensation chamber having a gas cushion located in a space above the volume of water, and an upper inlet end of the condensation tube extends...
