  • Patent number: 6068882
    Abstract: A thermal insulation is produced by forming aerogels interstitially within a fiber matrix. The resulting composite structures have substantially no fiber--fiber contacts. The insulating product is made by impregnating the fiber matrix with an aerogel forming precursor and supercritically drying the aerogel precursor under pressure. Drying is conducted prior to aging of the aerogel precursor.

  • Patent number: 5964004
    Abstract: The invention relates to tube cleaners for hygienic cleaning of tubes, e.g. endoscopic tubes. A first embodiment has a body made of resilient material extending axially and having a socket at one end for mounting of the cleaner to the end of the rod. Integral blades project out from the body, each blade having an arcuate outer edge to scrape along the inside wall of the tube. The blades are at axially spaced locations and, in end view, they overlap so that cleaning occurs around 360.degree.. A second embodiment has a core such as a wire, and the body and integral blades are moulded onto the wire core.

  • Patent number: 5846427
    Abstract: Improved devices for blood separations are provided based on the use of hollow fiber membrane arrays in extra-lumenal crossflow filtration. Blood is processed extra-lumenally across an ordered array of microporous hollow fibers to separate cells from plasma. By use of extra-lumenal crossflow filtration with suitably oriented fibers, the separation device is more efficient than existing devices which benefits a patient or donor by reducing extracorporeal volume.

  • Patent number: 5680120
    Abstract: A transportation safety apparatus and method for the detection of obstacles which lie off the line-of-sight or beyond the field of view of a moving vehicle entails shooting a laser beam through the air from a moving vehicle, capturing the beam and passing it to a fiberoptic relay which transmits a laser pulse to a distant site, and receiving a reflection thereof if the site is clear of obstacles. The pulses are received within about 10-20 microseconds per kilometer of relay length from the time of launching, permitting monitoring of the probe-site in real-time.
