Abstract: A telescoping waterway for adjusting the height of a firefighting monitor is disclosed. The telescoping waterway includes a hollow outer tube, a hollow inner tube within the hollow outer tube, and an actuator that moves the hollow inner tube relative to the hollow outer tube, wherein the hollow inner tube can be maintained in at least one intermediate position between a retracted position and a fully extended position.

Abstract: An apparatus for cooking a food item therein has a housing defining an interior and includes at least first and second opposed walls. A rotating member is positioned between the first and second walls of the housing, and the rotating member is capable of engaging and rotating the food item. A drive mechanism is mounted on the apparatus for rotating the rotating member. A heating element is positioned adjacent the second wall of the housing, and a blackbody radiator is positioned between the rotating member and the heating element. The heating element heats a first side of the blackbody radiator and a second side of the blackbody radiator emits radiation in a highly effective wavelength spectrum toward the food item. The apparatus also includes a self cleaning system for cleaning the interior.

Abstract: A method for subduing a fire (70) is disclosed. This method is performed by operating a jet turbine (20), having an exhaust (22), to direct the exhaust (22) into a moving front of the fire (72), generally against the movement of the front of the fire (72). A retardant (30), preferably dust, is directed from a supply tank (40) into the exhaust (22), through a pressurized conduit (42). Alternately, dust or other material (32) is lifted from the land around the fire (70) and blown into the fire (70), extinguishing the fire (70) or decreasing its intensity. To completely extinguish the fire (70), it may be necessary to further douse the fire with either or both water and a second retardant.

Abstract: A laser level with adjustable laser projection line comprises a support bracket, a housing, a switch, a laser generator which project a fanned laser beam to the surface of the work piece to form a line, and wherein a rotating mechanism is coupled to rotate the laser generator thereby causing rotation of the line. There is also a positioning device to position the laser level on an arbitrary surface.

Abstract: Assays are provided for rapid detection, with high specificity of the pathogenic form of prion protein responsible for neurodegenerative diseases affecting humans and animals, such as transmissible spongiform encephalopathy in bovine, sheep, and cats. Also provided are assays for testing animal feedstock, such as animal feed, for the presence or concentration of pathogenic prion protein. Results are available in from about 0.5 to about 20 minutes and preferably within from about 5 to about 10 minutes. The assays employ proteinase-K to remove normal prion protein from a biological sample, so that the sample may be analyzed by immunochromatography to determine the presence and concentration of pathogenic prion protein. Because the proteinase-K is immobilized on a solid support for in situ removal of interfering components, the present invention obviates the need for subsequent extraction of the desired analyte.

Abstract: A connector assembly (10) for releasably connecting a pair of conduits (12, 14) is disclosed. The assembly (10) comprises a first member (20) and a second member (40). The first member (20) has a nozzle (22) and the first member (20) is adapted to be connected to one of the conduits (12). The first member (20) includes an anchor (60) rotatably mounted on the first member (20). The anchor (60) has at least one resilient tab (62) extending therefrom. The second member (40) has an opening (45) that receives the nozzle (22). The second member (40) has at least one aperture (46). The second member (40) is also adapted to be connected to the other of the conduits (14). The tab (62) engages the aperture (46) to releasably connect the first and second members (20, 40).

Abstract: There is disclosed a method for making a pressure garment, comprising the steps of: defining 3D shape and pressure profile characteristics of a garment; specifying a knitting pattern for the garment; calculating yarn feed data for the knitting pattern to produce the defined shape and pressure profile characteristics; and, knitting the garment according to the knitting pattern and the yarn feed data.

Abstract: Broadcasting methods are disclosed which allow a user to choose between passive or active participation. Information is broadcast to a set-top box or from a database of content. Content is carried in segments which are scheduled into programs. Segments may be updated without altering the schedule which determines a program. A user may depart from a scheduled program or depart from a broadcast and enter a unicast, at will. The user may subsequently rejoin a scheduled replay or broadcast.

Abstract: The present invention provides a face guard for a sports helmet having at least two ear holes. The face guard includes a main body having an arrangement of elongated members. The face guard also includes a pair of quadrilateral projections for securing the face guard to the helmet, wherein the projections are integral with and extend from the main body. The projections are positioned below the ear holes in the helmet when the face guard is secured to the helmet. Also, the projections are positioned adjacent a lower edge of the helmet when the face guard is secured to the helmet. The projections are positioned below a rear lower edge of the helmet when the face guard is secured to the helmet. Each projection has first and second vertical members that are configured to engage a connector that secures the face guard to the helmet.

Abstract: An active-constraint robot (4), particularly for surgical use, is controlled by means of a series of motorized joints to provide a surgeon with real-time tactile feedback of an operation in progress. The robot system holds, in memory, a series of constraint surfaces beyond which it would be dangerous for the surgeon to go, and a resistive force is applied to the cutting tool (14) as the surgeon approaches any such surface. To improve the overall quality of feedback experienced by the surgeon, the resistive force applied to the cutting tool (14) depends upon the point of intersection (I) between the force factor applied by the surgeon and the surface. Further improvements are achieved by adjusting the tangential resistive force, when the tool is adjacent to the surface, in dependence upon the surrounding shape of the surface.

Abstract: Apparatuses, devices, systems and methods employing a material or combination of materials capable of emitting both far infared radiation and negative ions are provided. The material at least include a first part of, for example, a bio-ceramic, and a second part that includes an additional oxide material. The material can be used in a variety of different applications including, for example, internal engine combustion, natural gas combustion, water purification or the like.
