Show moreAn x-ray source for producing a uniformly intense area x-ray beam. The x-ray source includes a vacuum chamber. An area electron emitter is disposed at a first end of the vacuum chamber. A target material is disposed at a second end of the vacuum chamber and spaced apart from the area electron emitter. The area electron emitter and the target material are correspondingly shaped and/or correspondingly curved. The x-ray source also includes at least one high voltage power source. The area electron emitter is electrically connected to a negative pole of one of the at least one high voltage power source and the target electrically connected to a positive pole of one of the at least one high voltage power source.

Show moreOne embodiment of video transducing system supplies a reproduced video signal with compensated amplitude response so as to exhibit a substantial phase advance for recorded half wavelengths less than the thickness of the magnetizable layer, and a phase correcting network is inserted between the playback winding and the playback amplifier. In a further embodiment, amplitude and phase are partially compensated such that there is a substantial amplitude fall off and a moderate phase advance at the highest frequencies of the useful range, and such that the leading edge of a step function when played back has an overshoot of approximately one to six decibels.

Show moreIn the illustrated embodiment a video cartridge contains an endless loop record tape with a multiplicity of channels, and a pair of pivotal guide arms for holding a length of tape in a taut condition to facilitate loading of the cartridge with the tape threaded between a capstan drive assembly and a transducer head. The downward movement of the cartridge into the operative position serves to retract the tape guides clear of the operating tape path. A tape tension arm is provided along the tape path in the cartridge and is so arranged as to apply tension to the tape as the cartridge is unloaded from the transducing machine. The tape reel in the cartridge is suspended on a bearing ball so as to provide very low resistance to rotation.

Show moreAn apparatus for solid state shear extrusion pulverization of a polymeric material comprising an elongated hollow barrel having a feed zone, a heating zone adjacent to the feed zone, a powder formation zone adjacent to the heating zone, and a powder discharge zone adjacent to the powder formation zone. At least one screw is housed within the elongated hollow barrel. A hopper is provided for feeding the polymeric material into the feed zone of the elongated hollow barrel. Barrel heaters and coolers are provided for heating the polymeric material to a temperature less than its decomposition temperature in the heating zone and for maintaining the polymeric material below its melting point in the powder formation zone. The screw comprises a high shear screw section for applying normal and shear forces within the powder formation zone to form a powder of the solid state polymeric material.

Show moreRetroreflective glass or plastic beads have fluorescent properties when irradiated with ultraviolet light and are emplaced in signs in patterns indicative of alphanumeric characters, or embedded in a hot melt comprising road stripes or embedded in the road asphalt or aggregate during construction of the road, to provide effectively bright and clear indications of signs or the extent and direction of the road. The glass beads comprise spherodized soda lime, borosilicate, phosphosilicate or aluminosilicate glasses with low levels of rare-earth dopants mixed therein, such as compounds containing one of the rare earths, or lanthanides. The plastic beads may have fluorescent materials mixed therein, typically organic pigments or dyes based on coumarin and rhodamine or the like.
