Abstract: A wireless communication system employs a method and apparatus for accurately locating a communication device in the system. The communication system includes a system infrastructure that provides communication services to communication devices distributed throughout the communication system. Either on its own or, more preferably, responsive to a request from a requesting device for an accurate location of a particular communication device, the system infrastructure determines an approximate geographic location of the communication device. Based on the approximate location, the infrastructure transmits a request to the communication device for a more accurate location of the device preferably together with a map of an area that includes the approximate location of the device. The communication device preferably displays at least the map to a user of the device and, responsive to user input, transmits the more accurate location of the device to the system infrastructure.

Abstract: An apparatus and method for mixing a liquid component and a powdered component to form a bone filler has first and second syringes each having a barrel, a plunger and an exit port. The plunger is moveable with the barrel of each syringe along a longitudinal axis of the barrel. An end portion of each plunger extends beyond the end of each barrel when the plunger tip is spaced from the exit port and can be activated to move the plunger tip toward the exit port. A mechanism for mixing the liquid and powdered components is operatively connected to each of the barrels and plunger of the first and second syringes so that the relative sliding movement of first and second parts of the mechanism simultaneously moves the plungers and barrels of the first and second syringes relative to one another to move the combined liquid and powdered components back and forth between the first and second syringe.

Abstract: Bolt hole stress in rotor disks having bolted joints is reduced by passing relatively hot secondary flow path air (such as compressor discharge air) through each bolt hole to heat the disk from inside the bolt hole. In doing so, the temperature distribution in the area of the bolt hole is made more uniform and the stress is dramatically reduced. The bolted joint includes a bolt hole formed in a first rotor disk and a bolt disposed in the bolt hole such that a channel is defined between the bolt and the bolt hole. A first nut or abutment is attached to a first end of the bolt, and a second nut or abutment is attached to a second end of the bolt. A first passage associated with the first abutment provides fluid communication with the channel, and a second passage associated with the second abutment provides fluid communication with the channel, thereby allowing the relatively hot fluid to pass through the channel during engine operation.

Abstract: Haloalkaliphilic bacteria have been isolated from samples of soil, water, sediment, trona (NaHCO3.Na2CO3.2H2O) and a number of other sources obtained from in and around hypersaline soda lakes. These bacteria have been analyzed according to the principles of numerical taxonomy with respect to each other, as well as to other known haloalkaliphilic bacteria. In addition, these bacteria are further circumscribed by chemotaxonomic analysis. The bacteria produce various alkali- and salt-tolerant enzymes which may be used in various industrial processes requiring such enzymatic activity in a high pH, saline environment.

Abstract: The specification discloses a pallet orienting apparatus for use in a return lane of a pallet live storage system, wherein one or more empty pallets may be placed in the pallet orienting means in a generally upright position, the pallet being rotated to a pallet delivery position in which the pallet lies in a generally horizontal plane. A plurality of pallets may be simultaneously handled by the orienting apparatus, which may be linked to a computerized control system for a live storage warehouse. The specification describes preferred methods for handling empty pallets, in a palletized live storage system.

Abstract: A cage (14) for a split roller bearing (10) is composed of two semi-circular components (15) detachably interconnected at their ends. Each of the components (15) is itself constructed from a pair of blanks (17). Each blank (17) takes the form of a mild steel pressing with a continuous semi-circular wall portion (18) with spaced-apart projections (19, 20) at the sides. The projections (19, 20) are bent along fold lines (L, M) so that the wall portions (18) form the sides (24) of the cage and some of the projections (20) overlap at a centre region (30) of the cage and are fixed together. The rollers (11) are located in pockets (40) between side edges of the projections (19, 20).

Abstract: Machine readable coded markings carried on articles to identify various properties of the articles are disclosed. The coded markings are formed integrally of the article in the form of a sequence of areas having contrasting light scattering and reflecting properties incorporated on the article's surface. The areas are arranged in the form of neighboring blocks and empty spaces disposed around and outside of a central target area defined by a sequence of concentric continuous markings, the blocks forming a series of layers containing coded information. Each of the blocks is positioned side-by-side contiguous either with the outermost ring of the target or with a block in a previous layer.

Abstract: A process for producing a package comprising a composition contained within a closed water soluble envelope comprises the initial steps of moulding a first sheet of water soluble material to form at least one recess adapted to contain the composition, placing the composition in the at least one recess, placing a second sheet of water soluble material across the recess, and sealing the first sheet to the second sheet to form a continuous closed seal around the recess thereby closing the package. The or each closed package is conditioned in an environment of raised relative humidity for a period of time prior to or during the packaging of the package within a secondary pack. The secondary pack includes a moisture barrier to maintain the package within the secondary pack in a conditioned form.

Abstract: A water soluble package containing a fluid substance for release on dissolution of the package, the package having a dome shaped body portion for containing the fluid substance comprising a first sheet of a water soluble material thermoformed to form a body wall of the body portion, and a second sheet of water soluble material superposed on the first sheet and sealed thereto along a continuous region of the superposed sheets to form a base wall of the body portion.

Abstract: A dispersed-dot stochastic dither array is provided for rendering halftone images having excellent visual quality. For color printing, a separate threshold array is generated for each of the color planes, however, the stochastic screens are interlocked so that the threshold arrays are generated while considering the other color threshold arrays. In this manner, a blue noise distribution may be produced by the individual arrays as well as by any combination of the individual arrays. When generating a single threshold array for a color plane, a particular criterion is used to determine where the next threshold value should be located, and the selection of a threshold location in each array considers the criterion for all the threshold arrays being generated. By using the interlocked threshold arrays approach, the overall visual affect will be improved for both individual threshold arrays and for a combination of more than one of the threshold arrays.

Abstract: An endoluminal prosthetic device comprising axially repeating rings made up in turn of unit cells. The unit cells themselves are made up of circumferentially repeating patterns of multilayered strut members to form the ring. The rings may be axially connected to form a stent or an expandable housing for housing other medical device inserts. The multilayered struts, created by recessed slots cut from various regions in the strut members, permit improved radiopacity, increased flexibility during insertion stage into a lumen and better post-expansion conformability to the longitudinal shape of the body lumen, while providing increased rigidity and strain tolerance once the device has been expanded, as well as improved expansion ratio and fatigue characteristics. Variations on slot placement, length, orientation and shape with respect to the centerline of the strut members permit the optimization of a stent's strength, rigidity, strain and related mechanical properties.
