Abstract: Ingress and egress to closets and doorways through standard swinging doors requires that the area the door traverses be kept clear and is, therefore, space not usable for other purposes. The pivotal storage unit replaces doors with useful additional storage which occupies the full width and height of the door opening while permitting normal access through the doorway. The unit is mounted on hinges offset from the doorframe to permit full opening of the storage unit beyond 90°. The lower hinge incorporates a thrust bearing to support storage loads. A rolling support wheel on the base of the unit additionally supports the unit when heavily loaded. The unit can be formed in a variety of furniture configurations such as an armoire, computer work center, home entertainment center, pantry, desk, curio, vanity, etc. Two units can be used for double width doorways.

Abstract: The problem of how to select out of a large chemically accessible universe molecules representative of the diversity of that universe is resolved by the discovery of a method to validate molecular structural descriptors. Using the validated descriptors, optimally diverse subsets can be selected. In addition, from the universe, molecules with characteristics similar to a selected molecule can be identified. The validated descriptors also enable the generation of a huge virtual library of potential product molecules which could be formed by combinatorial arrangement of structural variations and cores. In this virtual library it is possible to search billions of possible product compounds in relatively short time frames.

Abstract: The concentration of potentially toxic hexavalent chromium, {Cr(VI)}, in chromium-bearing soils/materials existing in the form of soils, sludges, sediments, fill, industrial wastes, or other materials is decreased by applying and mixing a single reducing agent, ascorbic acid, to effect chemical reduction of Cr(VI) to a less toxic valence state. Ascorbic acid is added at ambient temperature in aqueous solution or slurry form and mixed with Cr(VI)-bearing soils/materials in amounts based on test results of representative samples of the material to be treated. Ascorbic acid may also be added in a dry form if sufficient moisture is present in the soils/materials to allow for dissolution of the ascorbic acid and reaction with the Cr(VI) in the material. The percentage reduction of the Cr(VI) concentration is greater and is achieved more rapidly than previously reported using other organic chemical reducing agents.

Abstract: A new computer implemented method for discovering structure-activity relationships has been discovered which utilizes weighted 2D fingerprints in conjunction with the PLS statistical methodology. This method produces a robust QSAR technique that can be automated. In addition, the MOLECULAR HOLOGRAM QSAR technique generates high quality QSAR models that are in many cases as good as or better than models arising from use of more complex and time consuming techniques such as CoMFA or Apex-3D.

Abstract: The use of biological screening purposes of a subset (library) of a large combinatorially accessible chemical universe increases the efficiency of the screening process only if the subset contains members representative of the total diversity of the universe. In order to insure inclusion in the subset of molecules representing the total diversity of the universe under consideration, valid molecular descriptors which quantitatively reflect the diversity of the molecules in the universe are required. A unique validation method is used to examine both a new three dimensional steric metric and some prior art metrics. With this method, the relative usefulness/validity of individual metrics can be ascertained from their application to randomly selected literature data sets.

Abstract: A beach buddy cart provides an easy means to transport items held on the cart platform to a sandy beach location. The beach buddy is provided with a contoured back and foldable seat so that it can serve as a beach chair once at the beach. In addition, retaining rings provide for the secure carrying of a beach umbrella. The carrying platform is supported at both ends when not being moved and is further supported by straps during transit. A pressurized sprayer mounted on the side of the cart back allows fresh water to be easily transported to the beach, warmed, and used to remove salt water and sand both from people and accessories.

Abstract: A PMC (PCI Mezzanine Card) is disclosed which complies with the IEEE 1386 form factor specification and incorporates a PCMCIA card connector so that readily available PCMCIA cards can be used with a PMC. By removing approximately one-half of the usual PMC printed circuit board, space is created in which to mount the PCMCIA connector so that it is contained within the allowed component envelope above and below the surface of the PMC circuit board (4). The PCMCIA connector (10) is mounted by its leads to a tab (9) extending from circuit board (4). Side rails (15) having an s-shaped bend (18) extend from the circuit board (4) and provide mounting support for the bezel supports (2) thereby meeting the overall size requirements for PMC cards under the IEEE 1386 standard. The design of this invention also permits securing PCMCIA cards in the PCMCIA connector with set screws (21) that may be used to push in on extensions (13).

Abstract: A computer implemented application development (authoring) system permits objects (such as VBX custom controls) to be graphically inserted into the program under development by dragging and dropping associated icons into one of four views. The properties associated with the object may then be assigned settings. Development of a complete application is accomplished by visually arranging, ordering, and interconnecting the objects without the necessity of writing any code. The four views of Output, Map, Multitrack, and Workform may be synchronized so that changes made to the program in one view are simultaneously reflected in all other views. The system generates as output a script listing the objects and their properties which is then executed by a separate run time program. The system permits use of objects written to a standard specification and the addition at any time of additional objects written to that.

Abstract: A chain saw stabilizing bench is disclosed which permits the sharpening of chain saw cutting teeth under field conditions. The bench consists of an extended planar platform for holding the weight of the saw and an upright holder for securing the saw bar against movement. The bench platform may be supported between upright supports or on any relatively flat surface such as the ground. A fastening means holds the chain saw securely to the bench. A seat at the end of the bench opposite the upright bar holder is provided for the person using the bench and positions the person so that both hands may work the sharpening file while easily and comfortably applying downward force on the file. The weight of the person using the bench keeps the bench from moving.

Abstract: A groundwater pollutant recovery system using the cone of depression approach, in which a sensing probe having liquid level sensors responsive to both water and pollutant levels and having attached to it the pollutant intake is deployed in a recovery well above the submerged water and pollutant pumps. The pollutant intake on the sensing probe is attached to the pollutant pump by an extendable hose so that the sensing probe may be raised and lowered in response to changing hydraulic conditions in the well, without the necessity of changing the water or pollutant pump positions. The recovery sequence is controlled by a microprocessor under the control of a program responsive to the liquid levels indicated by the sensors in the sensing probe.

Abstract: Comparative Molecular Field Analysis (CoMFA) is an effective computer implemented methodology of 3D-QSAR employing both interactive graphics and statistical techniques for correlating shapes of molecules with their observed biological properties. For each molecule of a series of known substrates the steric and electrostatic interaction energies with a test probe atom are calculated at spatial coordinates around the molecule. Subsequent analysis of the data table by a partial least squares (PLS) cross-validation technique yields a set of coefficients which reflect the relative contribution of the shape elements of the molecular series to differences in biological activities. Display in three dimensions in an interactive graphics environment of the spatial volumes highly associated with biological activity, and comparison with molecular structures yields an understanding of intermolecular associations. CoMFA will also predict the biological activity of new molecular species.

Abstract: This invention permits the dispensing of toothpaste onto a standard toothbrush using only one hand or limb and intended as an aid to disabled persons. The invention includes a toothpaste dispenser grasping member that fits over conventional commercially available upright toothpaste dispensers. A toothbrush holding tray is rigidly connected to the top of the toothpaste dispenser grasping member so that the bristles of a toothbrush placed on the toothbrush holding tray will be located below the nozzle of the toothpaste dispenser. To ensure that the bristles will be located properly under the nozzle, an alternative embodiment includes a toothbrush stop positioned on the toothbrush holding tray. The toothpaste grasping member may also have an opening in its side to allow one to view the window often placed in upright toothpaste dispenser to show how much toothpaste is left.

Abstract: The screening or security fence structure of this invention includes a plurality of spaced I-beam vertical support posts with standardized fence panels placed between them. While each fence panel is securely mounted to the I-beam posts, it is also firmly and contiguously connected through the posts to adjacent panels, so that the entire fence structure is linked together. By this configuration, an impact force on one of the fence panels is distributed along the fence. Additionally, the vertical side members of each fence panel frame abut the inside surfaces of the I-beam posts. If a fence panel is struck by a moving vehicle, the vertical frame member will jam against the I-beam flanges thus preventing the fence panel from breaking away and causing a safety hazard.Additionally, the fence fabric mounting hardware is secured within the I-beam channels thus reducing possible vandalism. In an alternative embodiment, a cable may be run the length of the fence inside the horizontal fence panel frame members.

Abstract: An apparatus and method for defatting and cooking meats which can be used in home and commercial kitchens whereby animal fats are removed during cooking without the use of high temperatures which may result in the formation of carcinogenic compounds. The defatting and cooking is accomplished by suspending the meat in a partially closed container above boiling water where it is exposed to steam. The meat is heated by the heat of condensation of the steam until cooked. During the cooking the temperature of the medium surrounding the meat within the container is monitored and regulated. While cooking, the animal fats from the meat are free to drip off into the boiling water below the meat.
