  • Patent number: 6272889
    Abstract: Various enhancements are provided to a pushbutton lock to enhance its security. One is the provision of button tips that are mounted on the ends of the button assemblies and spring-loaded to protrude from the face of the lock, regardless of whether the underlying button is “in” or “out.” By this arrangement, a bystander cannot readily see the button combination by the pattern of depressed buttons. This arrangement also reduces tactile feedback between the underlying button assembly and the externally available button tips, increasing resistance to pick attacks. A further enhancement is the provision of button bars between adjacent pairs of button tips. Whenever any of the button tips is manually depressed, the corresponding button bar is pressed into engagement with, and prevents movement of, a member that must be moved in order to unlock the lock.

  • Patent number: 6274122
    Abstract: A device is provided for the treatment of teeth including an outer layer of non-porous polymeric material forming a trough, an inner layer forming an inner lining of the trough, and a treatment layer including a treatment agent disposed between the outer layer and the inner layer. The inner layer allows penetration of the treatment agent through after an aqueous solution is introduced to the device. A device is provided for the treatment of teeth including an outer layer of non-porous polymeric material in the form of a trough, wherein the trough has an outside and an inside surface. An outer lining layer is proximate to the inside surface of the outer layer; the outer lining layer includes a material for retaining a treatment agent. An inner lining layer forms an inner lining of the trough, wherein the inner lining layer includes a water-permeable material. A treatment layer is disposed between the inner lining layer and the outer lining layer, wherein the treatment layer includes a treatment agent.

  • Patent number: 6274002
    Abstract: An automatic control system for a papermaking machine having a plurality of variable dewatering devices with moveable elements which engage the conveyor carrying the paper stock and are adjusted by electrical operating devices, such as servo motors or solenoid valves, to vary their water removal rate in response to control signals produced by a computer controller. A plurality of sensors are spaced along the path of the paper sheet downstream from the variable dewatering devices to sense the paper sheet characteristics including light transparency and mass, and to apply sensor output signals corresponding thereto to the computer controller. The servo motors have their shafts coupled to adjustment devices for cam mechanisms which adjust the moveable elements of the variable dewatering elements.

  • Patent number: 6270772
    Abstract: Two-domain MHC polypeptides useful for manipulation of antigen-specific T-cells are disclosed. These polypeptides include MHC class II-based molecules that comprise covalently linked &bgr;1 and &agr;1 domains, and MHC class I-based molecules that comprise covalently linked &agr;1 and &agr;2 domains. These polypeptides may also include covalently linked antigenic determinants, toxic moieties, and/or detectable labels. The disclosed polypeptides can be used to target antigen-specific T-cells, and are useful, among other things, to detect and purify antigen-specific T-cells, to induce or activate T-cells, and to treat conditions mediated by antigen-specific T-cells.

  • Patent number: 6271047
    Abstract: Methods and apparatus are disclosed for detecting a thickness of a surficial layer (e.g., metal or insulating layer) on a workpiece (e.g., semiconductor wafer) during a process for planarizing the layer, so as to stop the process when a suitable process endpoint is reached. Layer thickness is detected based on a spectral-characteristic signal of reflected or transmitted signal light, obtained by directing a probe light onto the surface of the workpiece. Example spectral characteristics are local maxima and minima of signal-light waveform, differences or quotients of the same, a dispersion of the signal-light waveform, a component of a Fourier transform of the signal waveform, a cross-correlation function of the signal waveform. Alternatively, the zeroth order of signal light is selected for measurement, or a spatial coherence length of the probe light is compared with the degree of fineness of the pattern on the surface illuminated with the probe light.

  • Patent number: 6268924
    Abstract: A server application associated with a document provides a document object with a print interface to support programmatic document printing. A client application interacts with the document object through the print interface to control printing. The print interface supports progress monitoring and print cancellation during printing using a call back interface of the client program. The print interface also supports opaquely conveying document-specific print options, so that the client program can perform subsequent print operations with the same or similar document object using the same print options without the client program manipulating the print options. The document object also has a print preview interface which supports programmatic print previewing.

  • Patent number: 6267967
    Abstract: Herpesvirus preparations, e.g. cultured HSV type 2, e.g. genetically disabled virus for vaccine use, can be purified, e.g. for subsequent pharmaceutical formulation, with solid phase affinity reagents containing sulfate- or sulfonate-comprising binding groups, e.g. sulfated polysacharide groups, e.g. heparin or dextran sulfate, and eluting e.g. with salt solutions. The process can be combined with other culture and harvesting steps.

  • Patent number: 6264222
    Abstract: A stairway assembly is pivoted between deployed and stowed positions. The stairway in one form includes a sliding support from which the stairway is suspended at a location spaced from a stairway pivot. A link, which may be adjustable in length, couples the coupler to the stairway. A snubber is provided to limit vibration of the stairway when stowed. An actuator, which may comprise an electric motor, is positioned above and overlies a portion of a platform of the stairway. Extension and retraction of the actuator pivots the stairway between stowed and deployed positions.

  • Patent number: 6266064
    Abstract: A visibility sorting method coherently computes a visibility ordering of a collection of moving objects seen by a moving camera in an animated graphics scene. The method detects whether an object occludes other objects. Objects that form an occlusion cycle are grouped together in the ordering. Objects are represented using convex polyhedra to facilitate occlusion testing. A fast occlusion test determines whether the spatial and angular extents of the convex polyhedra overlap. An exact occlusion test detects collisions between convex polyhedra and the silhouettes of the convex polyhedra.

  • Patent number: 6263379
    Abstract: A method and system for referring to and binding to objects using a moniker object is provided. In a preferred embodiments moniker object contains information to identify linked source data and provides methods through which a program can bind to the linked source data. A binding method is provided that returns an instance of an interface through which the linked source data can be accessed. The moniker object can identify source data that is stored persistently or nonpersistently. In addition, moniker objects can be composed to form a composite moniker object. A composite moniker object is used to identify linked source data that is nested in other data. In a preferred embodiment, the moniker object provides other methods including a reducing method that returns a more efficient representation of the moniker object; equality and hash methods for comparing moniker objects; and inverse, common prefix, and relative-path-to methods for comparing and locating moniker objects from other moniker objects.

  • Patent number: RE37288
    Abstract: A cutter for an endless cutter device having a body portion disposed in a substantially upright plane, a cutter portion on a rearward region of the body and a depth gauge portion on a forward region of the body. The depth gauge has a downwardly sloping planar upper surface with a multi-angular configuration. A rear edge of the depth gauge has a central portion which is highest and farther to the rear, with side portions extending forwardly and downwardly therefrom in diverging directions. A free outer edge intermediate the rear edge and forward edge of the depth gauge is the maximum width portion of the depth gauge. Converging edges progress forwardly from the maximum width portion to the front edge of the depth gauge. The heel of the body portion is clipped to permit limited rearward rocking of the cutter.
