  • Patent number: 6092429
    Abstract: A process parameter measurement device, and in particular a Coriolis mass flowmeter or vibrating tube densimeter, having a driver or drivers for inducing oscillation of at least one conduit. The drivers are attached at locations along the vibrating conduit selected to influence certain modes of interest. A driver is located near an area of maximum amplitude of a desired vibration mode and near an area of minimum amplitude of an undesired vibration mode. Various known experimental modal analysis or modeling techniques are used to determine the appropriate locations for one or more drivers. Multiple drivers located according to the present invention are used to influence, i.e., excite or suppress, multiple modes. In addition, multiple, separate drive circuits produce multiple, electronically isolated drive signals for delivering greater total power to the vibrating conduit.

  • Patent number: 5301557
    Abstract: An optimized Coriolis mass flow meter is disclosed which has improved stability to excitations caused by external influences. A primary source of improvement involves determining by modal analysis of the flow conduit a location for the sensor means that minimizes the influence of external excitation of one or more of the first in phase bending mode, the first out of phase bending mode, the first out of phase twist mode, the second out of phase twist mode, the second out of phase bending mode and the third out of phase bending mode.

  • Patent number: 5279539
    Abstract: A medical device is disclosed for enclosing an internal bodily organ or tissue during surgery. The device is a surgical pouch with two drawstrings. The first drawstring is made up of a resilient, wire-like thread for keeping the mouth of the pouch open during use, and is detachable from the pouch. The second drawstring is intended to cinch the mouth of the pouch closed after the organ or tissue is enclosed and the first drawstring is detached. It is composed of a compliant, bioabsorbable thread.A method of reducing or preventing post-operative ovarian adhesions is also disclosed. The method involves placing a bioabsorbable surgical pouch, especially the surgical pouch of this invention, over an ovary after a surgical procedure, and then cinching the mouth of the pouch closed to isolate the ovary from surrounding bodily tissue.

  • Patent number: 5007916
    Abstract: An absorbable fabric which effectively reduces the incidence of postoperative adhesions when used as a physical barrier at the operative site is a warp knit fabric of oxidized regenerated cellulose or other bioresorbable material. The barrier fabric is particularly characterized by having a density of 8 to 15 mg/cm.sup.2 and an open area porosity of 12 to 20 percent.
