Abstract: A coin holder opener having a housing with a central axis and a set of rollers rotatably mounted at an acute angle with respect to the housing and in a spaced relationship from each other and a central axis so that when a roll of wrapped coins are inserted into pressure contact and rotated, the rollers force the wrapper against an edge of a coin to compressively cut the coin wrapper located therebetween.

Abstract: An airflow director constructed for use with a separation column in a temperature-controlled air bath in a chromatographic oven cavity, wherein the airflow director includes at least a first baffle locatable with respect to the separation column and to the low pressure and high-pressure regions of the air bath, wherein the baffle is configured to direct air flow away from the high-pressure region before passing over the separation column. The temperature-controlled air thereby mixes with oven cavity air before passing over the separation column, which is thereby less subject to thermal gradients.

Abstract: An input cell to the core logic on an electrical component and an output cell from the core logic on an electrical component are provided with a first signal path for data, a second signal path for scan data, a flip flop positioned near the pad of the core logic for selecting between said first signal path for data and second signal path for scan data. The scan data is used to input special signals or vectors to the core logic and to read the results of the scan data after it has passed through the core data and has been manipulated thereby. Several of the electrical components can be electrically connected to one another. The output cell of a first chip is electrically attached to the input cell of a second electrical component.

Abstract: A method for rigorously reshaping a pair of overlapping digital images using a Digital Photogrammetric Workstation (DPW) is disclosed. The overlapping images are imported into the DPW as a pair of originally distorted images having an associated sensor model. The original images are triangulated to adjust sensor parameters. Orthophotos are created with a flat digital terrain matrix (DTM) to leave terrain displacements within themselves, and according to a sensor model and formula for exact projective computations. The orthophotos are aligned by rotation, and interior orientation coordinates of the equivalent vertical frame images are determined. The orthophotos are imported as a pair of overlapping equivalent vertical frame images according to the interior orientation coordinates. A digital terrain model is generated in the DPW using the overlapping equivalent vertical frame images. Another orthophoto is produced using the digital terrain model to remove the measured terrain displacements.

Abstract: A sleever apparatus includes an inner member with a central passage through which an item to be sleeved is passed. An outer member surrounds the inner member and defines a space between the members for holding a supply of containment material, which is preferably plastic sleeving. The apparatus has a handle which allows a user to hold the apparatus and walk the apparatus along the length of the item to be sleeved. As the user passes the item through the sleever apparatus, the containment material exits through a slit at one end of the apparatus in order to contain the item. The sleever apparatus may be formed of disposable materials, such as cardboard, and may be intended for a single use application. Alternatively, the sleever apparatus may be comprised of more permanent materials such as PVC or fiberglass.

Abstract: Compounds of formula I, ##STR1## wherein X represents naphthyl optionally substituted by alkyl or halogen; andp, q and r independently represent 2 or 3,and pharmaceutically acceptable salts thereof;processes for their preparation and methods for their use.

Abstract: An improved polycrystalline diamond composite ("PDC") cutter comprising a single or a plurality of secondary PDC cutting surfaces in addition to a primary PDC cutting surface, wherein at least two of the cutting surfaces are non-abutting, resulting in enhanced cutter efficiency and useful life. The primary PDC cutting surface is a PDC layer on one end face of the cutter. The secondary PDC cutting surfaces are formed by sintering and compacting polycrystalline diamond in grooves formed on the cutter body outer surface. The secondary cutting surfaces can have different shapes such as circles, triangles, rectangles, crosses, finger-like shapes, or rings.

Abstract: A method and ink-jet ink composition are provided for reducing crystallization of Acid Yellow 23 anionic dye in ink-jet ink compositions printed on transparencies and glossy media, both film- and paper-based. The method comprises formulating the yellow ink-jet ink composition in accordance with at least one of the following three conditions: (a) a first condition, wherein the yellow ink-jet ink composition includes about 6 to 9 wt % ethylhydroxypropanediol, about 3 to 9 wt % 2-pyrrolidone, and about 3 to 9 wt % diethylene glycol; (b) a second condition, wherein the vehicle of the yellow ink-jet ink includes a buffer in amount sufficient to maintain the pH of the ink-jet ink within the range of about 5 to 7; and (c) a third condition, wherein the cation of the inorganic salt component of the ink-jet ink comprises calcium ions to the substantial exclusion of magnesium ions.

Abstract: A support member for tanning beds or comparable devices is designed to have the various electrical components used in operating the tanning bed, or comparable device, on a removable cassette that can be readily removed and sent to be serviced independent of the tanning bed or comparable device. The support member comprises a housing which defines an open compartment in which the cassette is slidably disposed. The cassette has a rack for carrying the various electrical components attached to a front panel which closes over the compartment.

Abstract: Cellulosic particles, for example wood particles, stored in a pile are preserved by contacting the particles with a thiocarbonate composition.

Abstract: Circuitry for testing the ability of an intermediate range nuclear instrut to detect and measure a constant current and a periodic current pulse. The invention simulates the resistance and capacitance of the signal connection of a nuclear instrument ion chamber detector and interconnecting cable. An LED flasher/oscillator illuminates an LED at a periodic rate established by a timing capacitor and circuitry internal to the flasher/oscillator. When the LED is on, a periodic current pulse is applied to the instrument. When the LED is off, a constant current is applied. An inductor opposes battery current flow when the LED is on.

Abstract: A sign of fence post support includes an upper polygonal section from which depend a plurality of leg members. The upper section defines an inner socket within which a post bottom is placed and includes a plurality of inwardly directed tangs specifically formed to permit slicing into the material of a post bottom being urged into the socket, to provide a secure interlocking of a post to the support device. A pair of diametrically opposed leg members each comprises a pair of side plates of triangular configuration and disposed normal to one another such that during driving of the support into the ground, obstructions in the soil will urge the bottom tips of the leg member in an outward direction, further anchoring the assembly within the ground.

Abstract: Water-soluble iron complexes are produced by forming an aqueous reaction medium (a) comprising a sulfate source (e.g., ferric sulfate) and a ferric source (e.g., the ferric sulfate and a different ferric salt) and (b) having a pH and sulfate ion to ferric ion molar ratio sufficient to form the water-soluble iron complexes. Preferably, the molar ratio of sulfate ion to ferric ion in the reaction medium is about 0.5:1 to about 1.5:1. It is also preferred that the pH of the reaction medium be about 1 to about 3.
