  • Patent number: 6131521
    Abstract: A modular worktop, and method of assembly, including a surface member, a front edge, and a backsplash, the components preferably being removably attached to each other. Each of the surface member, front edge, and backsplash may be selected from a predetermined group of decorative surfacing options, resulting in a worktop that is aesthetically pleasing to the consumer or person selecting the components. Additionally, each of the components is sized and configured so as to bring assembly and installation within the skill range of the average consumer. Because the front edge is removably attached, the front edge is changeable at the discretion of the consumer, for example, for aesthetic reasons.

  • Patent number: 6121493
    Abstract: This invention relates to an isomerization process wherein hydrogenated aromatic amines are substantially isomerized to their thermodynamic form. These hydrogenated aromatic amines are presented by the formulas: ##STR1## wherein R is hydrogen or C.sub.1-6 aliphatic, R1 and R2 are hydrogen or C.sub.1-6 aliphatic, A is C.sub.1-4 or NH; n is 0-2, x is 1-3 and y is 1 to 2 except the sum of the y groups in Formula I may be 1.The improvement in the process comprises using a catalytic system comprising cobalt preferably in combination with another Group VIII metal selected from rhodium, ruthenium, platinum, and palladium and the metal, copper. Preferably the catalyst comprises cobalt in combination with rhodium or ruthenium wherein the weight ratio of cobalt to rhodium or ruthenium, calculated on metal content, is from about 0.2 to 100 weight parts cobalt per weight part rhodium or ruthenium and the isomerization is carried out in the presence of hydrogen.

  • Patent number: 6117625
    Abstract: A method of producing a composite image on an image recording medium from first and second component images, represented by digital image data, comprising the steps of converting the digital image data of each image into electromagnetic radiation image data; and forming the composite image by successively exposing the recording medium to the electromagnetic radiation image data of the first and second images so that the images are created on the medium in overlapping relationship to form a join region. The medium is doubly exposed, first by the image data of the first image and then by the image data of the second image. The intensity of the electromagnetic radiation representing the first image is progressively ramped off in the join region and the intensity of the electromagnetic radiation representing the second image is progressively ramped on in the join region.

  • Patent number: 5978981
    Abstract: A hair control device for pools/spas and a method for using the same includes a grate disposable in the pump inlet of a pool/spa with a plurality of elongate flow channels extending between a first end of the grate and a second end of the grate. The elongate flow channels are isolated from one another so as to decrease turbulence and to prevent hair from tangling or knotting behind the grate in such a manner that a person's head is held under water. Preferably, the channels of the grate will be at least 18 inches long. The channels can be linear, or can be disposed in a helical pattern through the housing of the grate.

  • Patent number: 5904990
    Abstract: Until recently, conducting polymers have been used as protective coatings. lthough these types of polymers appear to be effective in most cases, problems have resulted when attempting to bind these polymers to an aluminum surface. The polymers of this invention adhere extremely well to aluminum and aluminum alloys and thus, provide a very effective form of corrosion protection.

  • Patent number: 5883582
    Abstract: A method of reading multiple RFID tags located in a field of an interrogating antenna is based on periodic transmissions from the tags with large, non-transmission intervals between transmissions. The non-transmission intervals are fixed for a given tag, but are random between tags due to manufacturing tolerances in electrical components from which the tag is constructed, such that no coordination of transmissions from the interrogating antenna is required.

  • Patent number: 5777630
    Abstract: A method and apparatus are provided for displaying image and facsimile data on a host-based application display. A host computer generates control and download command data for displaying the image or facsimile data. The image and facsimile data is processed by a non-programmable-terminal (NPT) or a programmable work station (PWS) for presentation of a display screen. When a user requests another function, the NPT or PWS stores image information and sends image information to the host computer. The save image information includes cache image counter data, scaling and viewed image screen location data that is used to restore the displayed image and facsimile data when the user returns to the previous function.

  • Patent number: 5756802
    Abstract: Acetonitrile is produced directly from alkanes or alkenes by ammoxidation over a catalyst which is a silica-alumina exchanged with a metal of Period 4, Groups VIIA and VIII of the Periodic Table. The silica-alumina can be amorphous but is preferably crystalline zeolite. Preferred zeolite include ZSM-5, beta, NU-87 and USY. Cobalt is the favored metal for exchange. Particularly good results are obtained when the zeolite has been modified with a surface coating of silicon oxides prior to the metal exchange or modified with a boron or phosphorous containing compound followed by calcination. Ammoxidation of alkanes produce alkenes as a byproduct which can be recycled to the reaction to increase acetonitrile yield.
