  • Patent number: 9206140
    Abstract: The present invention relates to a method for recycling water in a melamine production process comprising—a wet process comprising the steps of aqueous treatment of a melamine melt from a melamine synthesis plant with an aqueous alkali containing solution and crystallization for producing solid melamine and a triazine containing alkaline mother liquor,—a wastewater treatment process comprising the steps of thermal treatment of said triazine containing alkaline motor liquor, and—a recycling process, whereby at least parts of the thermally treated alkaline mother liquor are being recycled to the wet process.

  • Publication number: 20090069721
    Abstract: A method and system for measuring the size of the palpable surface of the prostate in the physician's office. In one embodiment a membrane with a grid pattern is located proximate the prostate. A physician moves a measurement system, formed at the end of the index finger and located in a glove, between opposite margins of the prostate. The measurement system counts the grid elements between the margins that translate into a quantitative measurement of size of the palpable surface of the prostate. In another embodiment an accelerometer attaches to the end of the index finger to produce signals along multiple axes that a processing system converts into a measurement of the size.

  • Patent number: 7309319
    Abstract: A method and system for measuring the dimensions of the palpable surface of the prostate in the physician's office and calculating prostate volume, rate of growth and changes in rate of growth. A membrane with a grid pattern is located proximate the prostate. A physician moves a measurement system, formed at the end of the index finger and located in a glove, between opposite margins of the prostate. The measurement system counts the grid elements between the margins that translate into a quantitative measurement of size of the palpable surface of the prostate.

  • Patent number: 5908379
    Abstract: A urethral cap is provided for alleviating urinary incontinence when attached to the body of the user. The cap has at least a partially deformable cap body with a hand gripping portion and a body contacting encircling surface. The body defines a chamber so as to allow for a vacuum seal when applied to the body so that there is an atmospheric air pressure seal between the urethral cap and the body to prevent urinary flow beyond the urethral cap.

  • Patent number: 5590128
    Abstract: The user of a local computer node (i.e., a caller) selects a remote computer node (i.e., a callee) for a computer conference call from a display containing a directory of possible callees. In one embodiment, the directory is an alphabetical combination of a network list maintained by a network administrator and a personal list for the caller. The user of the caller can access and edit the personal list, but only access the network list. When displayed to the user, the possible callees from the personal list are distinguishable from the possible callees from the network list.

  • Patent number: 5524110
    Abstract: A computer-based conferencing system capable of selectively conferencing with a remote node over two or more different transports. A host processor controls the generation of local conferencing signals for transmission to the remote node over either a first transport or a second transport. The host processor also controls the processing of remote conferencing signals received from the remote node over either the first transport or the second transport. In a preferred embodiment, the first transport is an ISDN network and the second transport is a LAN network. In one embodiment, the computer system has a combined audio/ISDN board, a video board, and a LAN card. In an alternative embodiment, the computer system has a combined audio/video board, an ISDN board, and a LAN card.
