  • Patent number: 7828151
    Abstract: A corner protector, e.g. for a sheet of glass, has a pair of generally triangular side walls connected by a pair of substantially perpendicular bridging walls. The internal faces of the bridging walls are substantially flat and are separated by a recess. Internal channels are provided along the junction between the side walls and the bridging walls. The margins of the side walls which extend between the outer ends of the bridging walls are curved such that they are mutually offset from each other for most of their length. At least one of the side walls contains a through-aperture for receiving an adhesive pad which adheres to the protected article in use to hold the corner protector in place. A finger notch provides access to an edge of the adhesive pad to facilitate peeling in order to remove the corner protector.

  • Patent number: 7802343
    Abstract: A suction head for a vacuum cleaner comprises a hollow body including a pair of arms (1, 3) which diverge from predetermined region of the body at an acute angle. Each arm is formed with a channel (14) for the passage of air. An outlet opening (5) is located in the region of the body from which the arms diverge for the passage of air to a vacuum cleaner. A first continuous ground-engaging barrier (21) extends along the region of an inner edge (19) of one of the arms (1). A second continuous ground-engaging barrier (21) extends along the region of an inner edge (19) of the other of the arms (3). A gap (23) is formed between the first and second barriers (21) for the passage of relatively large particles of debris into the suction head.

  • Patent number: 7794862
    Abstract: The method for generating a hydrogen-rich stream from hydrocarbon fuels, ultimately to produce hydrogen gas, involves the following two steps performed in a cyclic fashion: (1) pyrolysis of the hydrocarbon fuel to obtain a carbon-rich fraction and a hydrogen-rich fraction; and (2) oxidation of the carbon-rich fraction, or a portion of it, for heat generation. The method involves the following optional steps: (3) steam gasification of part of the carbon-rich fraction to produce additional amounts of hydrogen and carbon monoxide; (4) water-gas shift reaction to convert carbon monoxide to carbon dioxide with the simultaneous formation of additional amounts of hydrogen; and (5) steam reforming of light hydrocarbons that may be produced in step (1) to produce more hydrogen and carbon monoxide.

  • Patent number: 7773532
    Abstract: A method is provided for enabling communication between first and second network nodes (1, 7) by way of a network address translation device (3, 9), which network nodes are each capable of communicating with a server (11). The first network node (1) establishes communication with the server (11) requesting communication with the second network node (7). The first network node then establishes communication with the second network node by way of the network address translation device (3, 9), including sending a plurality of first dummy packets from the first network node directly to the second network node. The server (11) establishes communication with the second network node requesting communication between the second network node and the first network node.

  • Patent number: 7735232
    Abstract: A bed-depth gauge consists of a guide member, a screed member, and means for assembling them for relative movement, for effective depth adjustment, in a vertical direction that is generally perpendicular to a bottom edge of the screed member. The guide member has a pair of arms that extend laterally, at different heights, which are used to engage and follow a fixed reference surface to thereby enable the bottom edge of the screed member to level and control the depth of both a base layer and also an overlying upper layer, comprising a bed prepared for installation of paving blocks and the like.

  • Patent number: 7718931
    Abstract: An electric heater (10) incorporates at least one heating element (20), at least one wall member (16) upstanding in the heater, and a device (42) is provided for detecting a cooking utensil (6) supported on an upper surface (4) of a cooking plate (2) overlying the heater. The device (42) includes at least one inductively-operating loop (44) of electrically conductive material having a plurality of portions (50, 52, 54) adapted to extend over and spaced from the at least one electric heating element (20) between fixed supporting regions (56, 58, 60, 62) on the at least one wall member (16). The at least one loop (44) of electrically conductive material is such that the plurality of portions (50, 52, 54) are substantially incapable of self-support as such at normal operating temperatures of the electric heater. The plurality of portions (50, 52, 54) are supported by elongate members (64, 66, 68) of heat-withstanding material.

  • Patent number: 7713914
    Abstract: A weak organic acid is used to effect the release of CaDPA from Bacillus or Clostridium endospores, rapidly and at room temperature, to enable detection and measurement of DPA and thereby the assessment of risk associated with exposure to Bacillus anthracis, Clostridium botulinum, and like spores. The method can be applied to airborne, food-borne, and water-borne spores, as well as to spores collected from surfaces or contained in body fluids, and analysis is advantageously carried out using surface-enhanced Raman spectroscopy.

  • Patent number: 7678863
    Abstract: A novel class of proton exchange membrane materials, sulfonated poly(phthalazinones), were prepared by modification of poly(phthalazinone). Sulfonation reactions were conducted at room temperature using mixtures of 95-98% concentrated sulfuric acid and 27-33% fuming sulfuric acid with different acid ratios in order to get SPPEK with degree of sulfonation (DS) in the range of 0.6 to 1.0. The presence of sulfonic acid groups was confirmed by FT-IR analysis, and the DS and structures were characterized by NMR. The introduction of sulfonic groups into the polymer chains led to an increase in the glass transition temperature and a decrease in the decomposition temperature. Membrane films were cast from solution in N,N-dimethylformamide or N,N-dimethylacetamide. Water uptakes and swelling ratios of the membrane films increased with DS and sulfonated polymers with DS>1.2 were water soluble at 80° C. Proton conductivity increased with DS and temperature up to 95° C., reaching 10?2 S/Cm.
