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...
The present invention relates to a device for reducing the aerodynamic drag of a cavity in a flow, said device comprising a blade disposed upstream from the cavity so that it overlaps at least one edge of the cavity and the corresponding wall of the corresponding vehicle, and so that it is in the vicinity of said wall....
A fluidic device having a plenum chamber, an input port to the chamber for receiving a supply of gas, and a power nozzle contiguous with the plenum chamber for generating a power jet. Means is located upstream of the power nozzle for controlling the directional flow of the power jet exiting the power nozzle. The contro...
An ultrasonic blood flow measuring and imaging system comprises a transmit-receive transducer for transmitting ultrasonic waves toward and into the human body and for receiving reflected echo signals which are then processed for use in a Doppler blood flow imaging and display system. Multiple ultrasonic pulse beams are...
A compiler method is disclosed which defines a data flow for a specific complex function to be executed on a plurality of data processing elements in a distributed processing system, by means of defining a plurality of control blocks which are associated with each task. The control blocks are in relocatable code so tha...
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 self-supporting laser diffuser flow energizer is described for improving the performance of radial flow lasers by providing novel means for pressure recovery, and comprises a self-sustaining suction means communicating with the laser cavity for changing the supersonic shock front configuration existing within a radia...
An audio probe feature which enables a user to select a wire or connector connected to a graphical object and "hear" the signals propagating on the wire or input to/output from the object. This provides a more complete and more informative debugging environment for certain classes of signals. The present invent...
An object of the present invention is to provide a hot-electrical-resistance type gas flow meter wherein a deterioration of a gas-cooled hot-electrical-resistance is prevented at the maximum flow rate, a decrease of sensitivity is prevented at the minimum flow rate and a wide dynamic range is achieve, and a structural ...
A pneumatic powder collector for determining the transfer efficiency of a powder spray system comprises a funnel for directing powder into a sealed collection chamber. A vacuum is drawn on this chamber by an air flow amplifier having an air flow inlet open to the chamber and an exhaust open to atmosphere. Contained wit...
A vehicle for receiving, transporting, measuring and delivering weighed amounts of flowable pulverulent material, such as wheat flour, has a blower which draws the material from a storage container to a selected one of a plurality of measuring containers where it is weighed and the weighed contents are then emptied by ...
A network switch having a shared memory architecture for storing data frames has a set of programmable thresholds that specify when flow control should be initiated on a selected network port. The network switch includes a queue for storing free frame pointers, each specifying available memory locations in an external ...
A multi-layer diaper includes a porous facing layer to be positioned adjacent an infant's skin, and absorbent batt, and a water-impervious backing sheet. The facing layer is provided with areas of preferential liquid flow, surrounded by areas of increased water repellency relative to the areas of preferential liqui...
A continuous flow analyzer of the type which introduces continuously a carrier liquid into a single tubular conduit to form a stable main carrier stream and injects predetermined volumes of reagent liquid and sample liquid in series into the main carrier stream. The analyzer reduces the consumption of the reagent and c...
An improved air turbine starter that includes fluid flow control devices. The devices may be check valves, for example normally open check valves. The check valves may be located in fluid flow paths between the starter and the gearbox to which it is mounted. The starter may also include a ring seal about the output sha...
This invention describes improved apparatus and methods for spin-on deposition of thin films applicable to the manufacture of semiconductor devices. The improved apparatus provides for controlled temperature, pressure and gas compositions within the deposition chamber. The improved methods comprise dispensing of soluti...
The present invention is directed to a process for cleaning large bone grafts using a pressure mediated flow of solutions, and to the bone grafts produced thereby where the bone grafts are suitable for transplantation into a human. The present method includes inducing a positive and/or negative pressure-mediated flow o...
