  • Flow meter for gaseous media
    Publication number: 20060053901
    Abstract: For the purpose of metering a flow of gaseous media, there is arranged a perturbation body in a measuring chamber which has a medium flowing through it, and an ultrasonic excitation signal is transmitted through the measuring chamber transverse to the direction of flow and at a point downstream of the perturbation body. The ultrasonic excitation signal after having traversed the measuring chamber is captured together with the ultrasonic excitation signal transmitted as structure-borne noise. The captured signal is squared first and then demodulated with a filter. An indication for the flow through the measuring chamber is derived from the frequency of the demodulated signal.

  • Stretchable composite sheets and processes for making
    Patent number: 7005395
    Abstract: This invention relates to an improved method for preparing stretchable multiple-component bonded composite sheets which involves bonding a fibrous layer of spirally-crimpable multiple-component continuous filaments or staple fibers to one or more non-spirally-crimpable layers using an array of intermittent mechanical, chemical, or thermal bonds, and heating the bonded composite to activate the spiral crimp of the fibers in the spirally-crimpable layer. Multi-layer nonwoven fabrics prepared according to the method of the current invention have an improved combination of strength, aesthetics, stretch-recovery properties, and textile hand and drape compared to multiple-component nonwoven fabrics known in the art.

  • Sleeve-like knitted structure for use as a castliner
    Patent number: 6981955
    Abstract: A castliner in the form of a three-dimensionally knitted sleeve comprises a microdenier yarn, and/or a spandex yarn, in particular, a spandex yarn having a flatter stress-strain curve than traditional spandex yarns. The use of the microdenier yarn contributes to the superior cushioning effect. The stretch and recovery properties of the particular spandex yarn contribute to superior fit and reduction of pressure points on the limb or body part to which the castliner is applied. Furthermore, the castliner is rendered water resistant and has significantly improved antimicrobial properties, both of which reduce incidents of skin irritation and unpleasant smell. As a result, the patient wearing the castliner of the invention is able to bathe and get wet without otherwise replacing the hard casting and castliner after such events.
