An even number of small holes of circular cross section are arranged adjacent the inlet to a supersonic nozzle sculpted in boundary layer, each small hole being in series with the nozzle and included in a pair of such holes spaced 90.degree. apart at opposite sides of said inlet.

Fluid nozzle with an axial flow passage, an inlet of area less than that of the passage directly downstream thereof, and an even plurality of radial orifices into the passage arranged in coaxial pairs 180.degree. apart.

Imploding a stream of compressible fluid under pressure at the outlet of a supersonic nozzle sculpted in boundary layer.

Computer-implemented methods of transmitting modules between a first computer and a second computer are disclosed. At the first computer, a module set is formed by selecting a sequence of modules from a collection of available modules. Each of the selected modules are associated with an application executing at the second computer. The selected modules may then be transparently streamed from the first computer to the second computer. The selection of modules is made in accordance with predetermi…

An electrokinetic streaming system with an oscillating drive is employed for the rapid, accurate reproducible detection of the fixed charge density of a coating on the inner surface of a flow restriction disposed in the path of oscillating plug-like liquid flow. As an application of this invention, identification of biological materials can be made and reactions can be detected between a reference coating of biological material and a coating of a second biological material, for example, an antig…

A cassette tape transport has a base for supporting the transport’s head assembly and drive motors which is tilted appreciably relative to the transport’s front plate through which the cassette is loaded into the transport. The unit also includes a cassette holder with a retractable slider and which is swingable relative to the base between a loading position wherein it is aligned with the slot and defines, with the base and plate slot, a right triangle and an operating position wherein it lies …

A streaming current detector includes an optical shutter rotated by the shaft of the motor which reciprocates a piston between electrodes in a bore containing sample fluid. An electronic synchronous detector is controlled by the output of a light detector whose source is interrupted by the optical shutter. The alternating current signals from the electrodes are connected to an operational amplifier having its inverting input connected to its output solely by a capacitor so that the output voltag…

The following specification discloses a streaming cartridge tape drive, wherein magnetic tape in a cartridge is driven over a magnetic head for purposes of recording and reading information magnetically on the tape. The information is written onto the tape and subsequently read and checked in a continuous streaming manner to assure the correctness thereof. The tape is driven over the first channel of the head in one direction wherein a write and read head on one portion of the tape effectively w…

An ultrasonic streaming current detector for developing on a continuous basis, electrical signal which is a function of the charge condition existing in the stream containing charged particles therein, for thereby facilitating the determination of the dosage of floculate to be added to a charge implacing species field stream, for thereby ultimately controlling floculation of such streams. The present invention employs a cross-shaped housing having cross-member and a longitudinal member, a piston…

A media server having at least one of a stride-based storage device space allocation scheme, stride-based method of striping data across multiple storage devices for continuous media streaming, server-based smoothing of variable bit-rate streams, distributed architecture, and fault tolerance.
