Abstract: A device for the application of solid particulate material to a target surface includes one or more containers for storing the solid particulate material and one or more transfer devices for transferring the solid particulate material from the containers to the target surface. Each container includes one or more gates positioned substantially at the container's outlet. Mechanisms are provided for controlling the extent to which each individual gate opens, while the device is in use; and for controlling the rate at which the transfer devices transfer the solid particulate material from the containers while the device for the application of solid particulate material to a target surface is in use.

Abstract: By providing components securable to anchor pins or screws of different diameters as well as providing clamps which hold associated pins in any position during adjustments, an external fixation or adjustable frame structure is provided which is capable of being quickly and easily assembled in any desired configuration. In the present invention, the frame structure is retained in any assembled configuration in order to allow final adjustments to be made, prior to the final securement of the frame assembly in the precisely desired configuration by closure of each clamp member. In this way, an entire frame assembly is capable of being constructed, adjusted, and readjusted in order to assure each component is oriented in the precisely desired position prior to final closure of the clamping members.

Abstract: A first aspect of the invention is an electrical connector that includes a housing formed to include first and second opposing ends and an elongated slot between the ends. The slot receives a connective edge of a printed circuit card. Closely spaced contacts located in the slot engage conductive pads on the printed circuit card. A first alignment member is formed integrally at the first end of the housing, to engage a non-polarized keyway during insertion of the printed circuit card into the elongated slot, aligning the printed circuit card relative to the contacts. A second aspect of the invention is the keying of the printed circuit card along a connective edge. The connective edge includes two connective regions which define a polarized keyway between the two connective regions. A third, non-connective, region located at one end of the connective regions defines a non-polarized keyway between the connective regions and the non-connective region.

Abstract: The drop-by-drop evaporation of a liquid or solution is controlled by monitoring the disappearance of each successive droplet and by actuating the deposition of the next droplet until the desired volume is deposited. In the case of a solution, non-volatile residue (NVR) is collected on a deposition surface plate as a relatively small mound. One of a variety of methods may be employed to measure the evaporative behavior of each droplet and to key the deposition procedure. The process is preferably carried out employing a clean deposition surface plate that is maintained at or below the boiling point of the particular liquid or solvent being deposited. The environment is preferably controlled so that inadvertent contamination is precluded from interfering, and thus the method permits the automatic, micro-processor controlled evaporation of liquids with the resultant deposition of non-volatile residues from solutions within relatively short periods of time.

Abstract: An envelope allows limited, yet sufficient, inspection of its contents for various types of contraband material, while simultaneously maintaining the privacy of a substantial portion of its contents. The envelope's front panel, back panel, and closure flap are each substantially opaque, and at least a portion of at least two of its edge portions on at least one of the front and back panels, are substantially transparent.

Abstract: A self-mode-locking (SML) mid-infrared (5 and 8 &mgr;m) quantum cascade laser is formed that comprises both a relatively thin dielectric insulating layer (i.e., less than one-half micron in thickness) overlaid with an optically highly lossy (i.e., absorbing) layer, with a relatively long (approximately 3.5 mm) optical waveguide. Evidence of mode-locking is obtained from the measured optical spectra and corresponding interferograms, as well as from the rf spectra of the photocurrent detected with a fast quantum-well infrared photodetector. An estimate for the pulse width of approximately 3 psec is inferred from these data.

Abstract: A recuperative heat exchanger is provided for the efficient transfer of heat between two fluids of differing initial temperatures. In a preferred embodiment, a cross-flow heat exchanger includes an array of parallel tubes that are further disposed within one or more beds of confined metal particulates confined by screens and through which a relatively cold fluid flows. A second relatively hot fluid is directed through the particulate beds in a direction perpendicular to the tube array. Because of the high thermal conductivity of the particulates, heat is conducted across the beds to walls of the tubes which comprise the walls of the confined beds in a direction substantially transversely to the fluid flow. In an alternative embodiment, a counter-flow heat exchanger preferably includes a number of adjacent beds of conductive particulates confined at their top and bottom by screens and on their sides by parallel solid plates. Adjacent plate beds are connected with plenums at opposite ends.

Abstract: This invention relates to a one step coaxial connector for an annular corrugated coaxial cable. The components of the connector include an outer conductor clamping back nut, a collet and a body. The collet (1) enhances electrical performance by providing a full 360 degree contact with the outer conductor. In addition, an O-ring is used to provide a seal between the back nut and outer conductor of the cable. When the back nut (2) is screwed into the body (5), the collet (1) is forced further into the interior portion (11) of the connector body (5). The resilient fingers of the (1) collet are forced to close radially around the first corrugation groove (3) of the cable's outer conductor. In addition, an O ring (4), that initially resides in a cavity (12) created by the collet (1) and the back nut (2), is forced into a corrugation groove of the cable's outer conductor. A bore (6) on the back nut (2) provides the proper diameter to compress the O-ring (4) to provide a tight seal.

Abstract: A laser transmitter is provided including a specialized compensator assembly damping mechanism. In accordance with one embodiment of the present invention, a compensator assembly position detector is arranged to detect a position X1 of the compensator assembly with respect to the X-axis, and a position Y1 of the compensator assembly with respect to the Y-axis. The compensator assembly damping mechanism includes an X-axis magnetic damping mechanism, a Y-axis magnetic damping mechanism, and a rotational damping mechanism. The active feedback circuit is arranged to (i) drive the X-axis magnetic damping mechanism so as to increase a damping force generated by the X-axis magnetic damping mechanism as a rate of change of the signal indicative of the position x1 increases, and (ii) drive the Y-axis magnetic damping mechanism so as to increase a damping force generated by the Y-axis magnetic damping mechanism as a rate of change of the signal indicative of the position y1 increases.
