A seal for restricting leakage of a fluid from a first chamber, through a gap between two components, to a second chamber is provided. A slot is formed in each of the two components. The slots face one another and are open to the gap. Each slot contains a longitudinal axis, an upstream surface proximate the first chamber and a downstream surface proximate the-second chamber. Disposed in the slots and spanning the gap is a bridging assembly comprising first and second bridging elements. Each brid...

A character display comprises fifty-nine segments arranged into rows and columns. Twenty eight of the fifty-nine segments define a periphery of the display, eleven additional segments define horizontal and vertical dividers that define four quadrants, and five additional segments are disposed in each of the four quadrants to define diagonals thereof.

A novel transmitter circuit is disclosed for receiving of an input signal and for providing of an amplitude increased RF output signal. Pluralities of switching power amplifiers are disposed along two signal propagating circuit branches and utilized for increasing a magnitude of the input signal, to form an output signal, which is a magnitude increased version of the input signal. Each of the switching power amplifiers utilizes switching elements having various magnitude increasing capacity and ...

Various embodiment comprise silicon-on-insulator waveguide designs that simultaneously achieve both high optical confinement, low-loss, and provide for electrical connections. In certain embodiments, high index contrast waveguides comprise a central elongate waveguide portion and a segmented portion comprising a single thin layer of Silicon-On-Insulator that achieves both high optical confinement and minimal insertion loss. Other devices, such as chemical and biological sensors, and optical elem...

Systems and methods for encoding and decoding document images are disclosed. Document images are segmented into multiple layers according to a mask. The multiple layers are non-binary. The respective layers can then be processed and compressed separately in order to achieve better compression of the document image overall. A mask is generated from a document image. The mask is generated so as to reduce an estimate of compression for the combined size of the mask and multiple layers of the docume...

A circuit for programming the inflation and deflation of a five segmented balloon pump as used in circulatory assist blood pump systems is disclosed. The rising and falling edges of wave pulses are used by a volume transducer to create a volume signal corresponding thereto. Means are provided to produce a plurality of signals corresponding to the rising edge of the waveform and a plurality of signals corresponding to the falling edge thereof. These signals are used to activate the various valves...

Confronting faces of a segmented duct of circular cross-section are provided with mutually opposing grooves running transverse to the front plane of the duct, the grooves each having a tapered surface, the tapered surfaces of opposing grooves being in mutually facing relationship with each other. A thin flat rectangular plate bridges the gap between the tapered surfaces, having one of its longitudinal edges resting on each surface. A net force on the plate created for example by a pressure diffe...

A segmented friction member assembly for a disc-type brake or clutch in which segmental facing members overlap heat-absorbing segments keyed to the rotating or nonrotating structure at a configured peripheral edge. Torque is transmitted from the facing members to the segments by interlocking members extending between opposing facing members and engaging recesses in the side edges of the heat-absorbing segments. Slanted surfaces of the recesses direct the components of the torque force being tran...

A clamping device for nuclear reactor cores wherein a plurality of hydraulic cylinders act directly to open or close a tilting segment core clamp, the clamp exerting a radial inwardly directed force of constant magnitude on the reactor core yet is releasable upon reversing the direction of fluid on a piston within the hydraulic cylinders thereby releasing the fuel elements within the core.

Apparatus for molding tires providing means for actuating a segmented mold having two annular sidewall molds and a plurality of tread mold segments readily installed, removed, and interchanged therein. The segments are moved radially inwardly by a closing mechanism associated with or attached to a first part of the apparatus which carries one sidewall mold and a second mechanism, independent of the closing mechanism, for moving the respective tread molding segments to be moved further outwardly ...
