Abstract: A solid ink jet nugget is contained in a first sleeve having opposite open ends and a flap at one open end movable into the sleeve towards the other open end. A second sleeve is placed about the first sleeve with its opposite ends directed generally at right angles to the direction of the open ends of the first sleeve. The second sleeve is then heat-shrunk on the first sleeve to close the open ends of the first sleeve. Prior to loading into an ink jet apparatus, the second sleeve is removed and the flap is pushed into the first sleeve against the nugget to discharge the nugget from the open end and into the ink jet apparatus.

Abstract: A film package including sheets of imaging media or film sandwiched between upper and lower stiffeners and enclosed by an envelope. Adhesive strips secure the stiffeners together at overlapping tabs formed on opposite sides of the stiffeners. The stiffeners with the film sheets are removed from the envelope by opening one side of the envelope. The adhesive strips also have tear strips for allowing removal of the upper stiffener after the package has been placed in a drawer of a printer with the aid of offset tabs on the stiffeners which indicate and assure proper orientation. A notch in the corner of the lower stiffener allows a signal to be passed to indicate whether the upper stiffener has been removed. The lower stiffener is also apertured to receive a signal for indicating whether any film sheets remain on the stiffener while in the drawer of the printer.

Abstract: The present invention relates to new methods for producing cellulose with high crystallinity by enzymatic hydrolysis and to novel cellulosic materials produced by those methods which exhibit a wide variety of DP's. The method is especially useful in producing microcrystalline celluloses.

Abstract: A wastewater treatment system incorporates three interconnected, but separately controlled, processes to enhance biological phosphorus removal. The first process is a mainstream biological treatment process utilizing aerobic and solids separation zones and the provision of return activated sludge. The next is a first sidestream process for anoxic/anaerobic "selection" of desirable BPR organisms. Finally, a second sidestream process serves to ferment organic material in some of the return activated sludge to produce food utilized in the first sidestream selection process. The system permits the three processes to be separated from each other by creating two sidestreams, allowing all three processes to be controlled separately and optimized in satisfying their own specific goals.

Abstract: A method for entering data into a computer utilizing a pop-up keyboard includes the steps of popping-up a keyboard associated with a selected field area displayed by the computer in response to a predetermined series of strokes formed by a pointer and modifying the symbols in the selected field area either in response to the selection of key field areas displayed on the popped-up keyboard or to the forming of handwritten symbols in a display field area of the popped-up keyboard with the pointer.

Abstract: A module model pile tool in situ testing of soils. The tool has an upper instrument section, a lower anchor section, and an axial slip joint located between the instrument section and the anchor section. The anchor section may be configured to model either open-end or closed-end piles. In the open-end configuration, a vent and vent valve are provided to vent trapped fluid during the initial stages of installation by remaining open only to a predetermined depth so as to permit formation of an undisturbed soil plug and to close in order to prevent fluids from being vented into the actual soil to be tested. The instrument section includes instrumentation for measuring axial loads, axial accelerations, pore water pressure, and total lateral pressure. Instrumentation for measuring axial displacement are included in the slip joint. The tool is rugged enough to permit installation by pile driving, and the instrumentation may be monitored both during and after installation.

Abstract: Pellet trays bearing rows of fuel pellets of known enrichment concentrations are retrieved from selected storage elevators and successively conveyed to a zone makeup machine. Parallel rows of pellets are raked from each tray and advanced over a longitudinally elongated, grooved loading surface into abutment with a selectively longitudinally positioned stop. A zone makeup carriage makes up the pellet rows to a prescribed, common zone length, which are then weighted and advanced in parallel by a vibratory loader into a plurality of cladding tubes arranged in parallel loading positions by tube handling apparatus. Overall operation is coordinated by a system controller to concurrently load the cladding tubes with multiple pellet zones of varying enrichments and lengths in automated fashion.

Abstract: A fiberoptic sensing system comprising a light source, a sensor responsive to external stimulus, an optical fiber connected to the light source and the sensor, a detector arranged to receive light from the optical fiber, and output electronics electrically connected to the detector. The sensor includes a reflective surface arranged so as to reflect light from the optical fiber. This reflective surface is movable relative to the optical fiber. The light source comprises a light-emitting diode and a reference diode electrically connected to the source of electrical energy and to the light-emitting diode. A beamsplitter is disposed about the light source, the optical fiber, and the photodetector. The detector includes a transimpedance amplifier and a RMS to DC converter. The output electronics includes a gain control and a offset control. The sensor may be either a temperature sensor or a pressure sensor.

Abstract: This invention relates to an apparatus for aiding the holding and turning of bound sheet music, which apparatus comprises a holder having left and right pockets formed internally of backing members for firmly grasping music pages which are not presently being played, leaving free those pages which are to be played, and incorporates transparent stiffening members for each free page to ensure its laying flat against the held pages, to each stiffening member including a color coded tab member for separating and quickly engaging each page, and an element formed on each backing member for placing the music at a height above the bottom edges of the backing members such that the music pages swing freely and without engaging a conventional restraining ridge normally found on a music supporting instrument.

Abstract: Improved chilling apparatus for aircraft meal tray storage and/or serving carts utilizes a slidable tray type of bunker member for receiving dry ice or other cooling material. The bunker member is preferably of thermoformed plastic, is insulated on its bottom and sides, and has a channeled bottom which supports pieces of dry ice while permitting air to be circulated by a blower under the dry ice pieces as well as around and over them. At its downstream end, the bunker has an air flow turning surface and an air discharge opening through its bottom. At its upstream end, an opening directs return air which has passed over the meal trays to an angularly positioned blower located in the cart housing above the inlet end of the bunker.

Abstract: A spacer unit, a discharging gun and a method of retaining a spacing to avoid loss of elastomeric seal between two surfaces are described. The system is particularly useful in the glazing trade for sealing large plate glass panes into aluminum frames. Each unit comprises a plurality of blocks skeletally inter-connected by webs. The cross-sectional area of the blocks and webs presented to a compressive force is still small relative to the cross-sectional area lying within the outer periphery of the unit.

Abstract: A pipe handling device for transporting pipe, drill collars, or like tubular members between the elevated drilling floor of a well derrick and a lower storage area has a pair of support cables extending between the rig floor and the storage area. A pipe trolley means rides the support cables and is movable along the support cables by a third cable to transport pipe from the storage area to the rig or to lay pipe down from the rig to storage. A cable draw works, typically in the vicinity of the storage area, anchors one end of the support cables and is provided with a take-up mechanism for the support cables to enable them to be slackened to enable a pipe to be loaded into or unloaded from the pipe trolley means in the storage area and thence tensioned to facilitate the travel of the trolley to the elevated rig floor.
