Abstract: An energy recovery system and method for laundry systems that transfers heat from warm exhaust air to intake air. The system and method includes a thermal wheel adapted to absorb heat from an exhaust air stream and discharge heat to an intake air stream for preheating the intake air. The system and method further includes a lint management system for clearing or otherwise managing lint buildup on the thermal wheel, and a bypass damper for admitting non-preheated intake air, particularly for use during a cooldown cycle.

Abstract: An optical image enhancement system provides improved image contrast in imaging of a target in high temperature surroundings such as a furnace. The optical system includes a source of vertically polarized light such as laser and a beam splitter for receiving the light and directing the light toward the target. A retardation plate is affixed to a target-facing surface of the beam splitter and a vertical polarizer is disposed along a common optical path with the beam splitter between the retardation plate and the target. A horizontal polarizer, disposed in the common optical path, receives light passing through a surface of the beam splitter opposed to the target-facing surface. An image detector is disposed at one end of the optical path. A band pass filter having a band pass filter characteristic matching the frequency of the vertically polarized light source is disposed in the path between the horizontal polarizer and the image detector.

Abstract: An interactive user support system for a document processing system or an image producing device controls the operation of the machine using an internally stored knowledge base derived from information and rules provided by expels in the field. A plurality of sensors monitor the operation of the machine and a variety of user actions. If the system determines that the user needs help, by comparing the operation of the machine with the information and rules in the knowledge base, the system will interrupt the user and offer or provide assistance. If the user is performing proper steps to correct a problem or perform a specific job, the system will not interrupt the user. Additionally, the user may query the system for assistance or direction. The result is a more efficient document processing system or image producing device for use in any environment and able to be operated by a variety of users having a range of needs and abilities.

Abstract: A reusable hypodermic syringe assembly (200) comprising a syringe (218) having a barrel shaped portion (214) with an opening (280) therein, a cartridge (202) insertable into and removable from the barrel shaped portion (214) of the syringe and containing a medication (262) into a patient from the cartridge (202) with the needle (210) and the medication (262) being sealably contained within first (204) and second (260) separately sealed compartments, respectively, within the cartridge (202) before injection of the medication. A plunger (224) functions to push on the second compartment (204) and thereby extends the distal end of the needle (210) out of the cartridge (202) and the proximal end of the needle (213) into the sealed second compartment (204) containing the medication before the injection of the medication (262), without the needle (210) being touched by human hands.

Abstract: A service building (10) having a base assembly (20) formed with a perimeter support portion (21) and a floor portion (22). The perimeter support portion (21) utilizes weight bearing side rails (23) with one or more transverse, weight supporting beam means (35) extending between at least one pair of opposite side rails (23). Decking sheets (30), insulating mats (44) and sump pans (48) are supported from the side rails (23) and beam means (35). Wall panel assemblies (60) are secured to the perimeter support portion (21) by sill connector assemblies (78). Post assemblies (105, 135 and 165) between the wall panel assemblies (60) secure adjacent wall panel assemblies together. A roof (not shown) may be secured to the service building (10) using connector assemblies substantially identical with the post assemblies.

Abstract: Cartridge magazine for semi-automatic firearms has a base, side walls and a front and rear wall. The front wall has an opening at its upper end for the feeding of cartridges into the chamber of the firearm. The magazine includes a spring and a spring follower which feeds the cartridges upwardly toward the feed lips on the upper edge of the side walls of the magazine. A guide member extends inwardly from opposed sidewall portions of the magazine to engage the extractor groove of the cartridge being advanced toward the feed lips. Each guide member is formed by die lancing the side walls of the magazine at a distance from the feed lips greater than the cartridge radius, but less than the diameter thereof. Each member has an upright edge portion disposed at an oblique angle to the real wall of the magazine such that it is generally perpendicular to the axis of the cartridges being fed by the magazine spring follower.

Abstract: An apparatus in which an altered copy of an original document is produced. An editing device associated with an electrophotographic printing machine changes the information in the original document and generates a signal indicative of the changes therein. A liquid crystal display overlays the original document. The areas selected for editing are indicated on the liquid crystal display.

Abstract: A cartridge assembly including a processing cartridge removable therefrom for use with and insertion into an electrostatographic reproducing apparatus is provided.

Abstract: An automatic printed circuit board tester in which a laser beam is directed onto and scanned around solder pads and foil regions of a printed circuit board, and errors in structure are determined by detecting patterns of scattered light and comparing these patterns with similarly obtained ones from a properly constructed board.

Abstract: An automatic hybrid holograhic non-destructive testing (HNDT) method and system capable of detecting flaws or debonds contained within certain materials. This system incorporates the techniques of optical holography, acoustical/optical holography and holographic correlation in determining the structural integrity of a test object. An automatic processing system including a detector and automatic data processor is used in conjunction with the three holographic techniques for correlating and interpreting the information supplied by the non-destructive systems. The automatic system also includes a sensor which directly translates an optical data format produced by the holographic techniques into electrical signals and then transmits this information to a digital computer for indicating the structural properties of the test object. The computer interprets the data gathered and determining whether further testing is necessary, as well as the format of this new testing procedure.

Abstract: A projection system for the display of parallax and perspective of a real image from a hologram in which a reference beam is projected in a sequence of several projections at selected angles of perspective through the hologram, this sequence being rapidly performed. The resulting angular spaced images emitting from the hologram are directed onto a mirror which is coordinately tilted to reflect all of the resulting images in register onto a screen where they appear as a single three-dimensional image.

Abstract: A holographic motion picture camera for producing three dimensional images employing an elliptical optical system and where there is provided in one of the beam paths (the object or reference beam path) a motion compensator which enables the camera to photograph faster moving objects.
