  • Patent number: 6231053
    Abstract: A gasket for fuel cells includes a gasket body composed of a metal or resin sheet and having openings, and a sealing section composed of a liquid rubber vulcanizate. The sealing section is bonded to the gasket body at low pressure. The inner face of each of the openings is covered with the sealing section. The gasket precludes generation of contaminants, such as ions, by the reaction of working fluids with the material constituting the gasket body, allowing high generating efficiency of the fuel cell.

  • Patent number: 6230352
    Abstract: A safety crib sheet and a safety crib sheet mattress assembly to reduce the risk of infant smothering and strangulation. Pieces of material are sewn such that the resulting sheet can not be installed or dislodged from the mattress without substantially destroying the sheet or deforming the mattress. In one embodiment, a mattress is formed in two subsections coupled along a fold line. The mattress must be folded in half along the fold line to install or dislodge the sheet. In another embodiment, a conventional crib mattress is used with a sheet that covers a substantial portion of the underside of the mattress and is sufficiently unelastic that the mattress must be significantly bent at least at the corners to permit the sheet to be installed or dislodged.

  • Patent number: 6230348
    Abstract: The present invention is directed to a neck rest moulded from a foamed material and having a rear pillow portion of a generally tubular configuration and two generally parallel laterally extending support sections extend at right angles from the front face at each end of said pillow portion. The opposing inner surfaces of the support are curved to form a keyhole shaped space between the support sections sized to permit the neck rest to comfortable fit around a person's neck without feeling yoked. The top surfaces and bottom surfaces of said support sections are preferably flat with rounded, the top surface of the pillow portion is higher than the top surfaces of the support sections and is curved to fit comfortable against the nape of the users neck. A flocking material is applied to the exterior surfaces of the neck rest.

  • Patent number: 6230347
    Abstract: The use of particulate stuffings such as down or fiberfill in the construction of orthopaedic pillows has previously been limited due to formidable intrinsic difficulties: On a curved wedge of support, with natural turning movement of the sleeper, fiberfill will tend to “avalanche” downhill, settle and pack down to obliterate any initial toricity or inflected curvature. Hence the sleeper is awakened to refluff or to punch the missing inflection back into place. Though simple internal partitioning can initially delay the scenario, in due course nuisance fiber sequestering and impeded normal hand refluffing are the results. The present invention focuses on structurally overcoming these impediments to the orthopaedic use of particulate fillings. It notably provides a pillow that manifests to the sleeper as downy soft, and comfortingly restful.

  • Patent number: 6230428
    Abstract: A frame connector for quickly and easily attaching two picture frames together in a stable manner has a support arm and a coupling member on each end. A coupling member may be a slider, snap, wedge or spring. A slider frame support attaches easily to either metal or wood frames. A coupling member for a slider frame support may be a flat piece for screwing or nailing to a wood frame, or may be slid into the channel of a metal frame. Holes, slots or spikes for attaching to a wood frame may be incorporated into any of the coupling members. A slider frame support includes a screw hole for a screw that secures the slider support to a channel of a metal frame. A snap frame support attaches to a channel of a frame by fingers that snap into the channel. A wedge frame support secures itself in a channel of a frame by wedging itself within the channel. A spring frame support secures itself in the channel of a frame by spring-like fingers that press against the channel walls.

  • Patent number: 6226909
    Abstract: A printed display sign particularly for use with a light box reverse printed on its rear face with information, typically a menu for a fast food outlet. The information includes product names and aligned with each product name is a rectangular transparent window area where the sign is not printed. The rear of the sign is painted with a white diffusing layer which covers the entire rear surface of the sign apart from the windows and the areas bordering the windows which are not coated with the diffusing layer so as to leave a rectangular dark border or frame around each window. Labels having a size larger than that of the window but preferably smaller than that of the outer edge of the border can then be located essentially within the window using the outer edge of the border as a guide. The front of the label is printed with price indicia and if the label is correctly applied to the window, which can be checked by reference to the border, the price indicia should align correctly with the product name indicia.

  • Patent number: 6226907
    Abstract: A two-dimensional display having a three-dimensional visual appearance has printed on a substantially flat or planar surface a predetermined message or information. Superposed over the message is a lenticular lens. Adjacent to the message are a series of spaced apart lines which may either be coplanar or non-coplanar relative to the message. The spaced apart lines are arranged so that they are in a non-registration relationship with the spacing of individual lenticules forming the lenticular lens. The display produces an appearance of having the lines float or move as a viewer's focal angle or perspective of the display changes. A method for making such a display is also provided.

  • Patent number: 6223371
    Abstract: A method of manufacturing mattresses is achieved by providing first and second layers of latex material having different indentation load deflection values. Each layer is then cut lengthwise along a longitudinal plane, preferably a medial plane to define first and second layer portions of the first and second layers each of an identical height. The layer portions are then cross united and adhesively bonded together thereby producing a mattress possessing a composite load deflection value dictated by the different indentation load deflection values of the starting layers. Preferably matching recesses are formed in the first and second layer portions of both layers. Medial recesses receive postural inserts of relatively high ILD values, whereas transverse recesses at headed foot sections are aligned to define voids at the foot and head sections of the mattress to provide head and foot relief.
