  • Patent number: 5947910
    Abstract: The technique for detecting extravasation during the injection of fluid into a patient involves the establishment of a baseline representing impedance at the zone of the injection prior to the injection starting. Extravasation is signaled when at least two characteristics appear. First is that the impedance varies from the baseline more than a predetermined amount in more than a predetermined number of discreet time slots called epochs herein. Second is that, the rate of change of the impedance, which is called the slope herein, is consistently greater than a predetermined amount.

  • Patent number: 5948213
    Abstract: A process is disclosed for producing 1,1,2,2,3,3,4,4-octafluorobutane. The process involves (a) reacting a mixture comprising 2,2,3,3-tetrafluorobutane and chlorine to form a mixture of chloro-compounds wherein compounds of the formula C.sub.4 H.sub.x Cl.sub.6-x F.sub.4 (where x is 0 or 1) comprise at least about 50 mole % of the mixture of chloro-compounds; (b) contacting certain chloro-compounds from (a) and hydrogen fluoride with a fluorination catalyst to form a mixture of fluoro-compounds; and (c) contacting certain fluoro-compounds from (b) and hydrogen with a hydrogenolysis catalyst to produce CHF.sub.2 CF.sub.2 CF.sub.2 CHF.sub.2. Sufficient chloro-compounds formed in (a) and sufficient fluoro-compounds formed in (b) are recycled to provide a selectivity to CHF.sub.2 CF.sub.2 CF.sub.2 CHF.sub.2 of at least about 75% based upon the moles of CH.sub.3 CF.sub.2 CF.sub.2 CH.sub.3 reacted in (a).

  • Patent number: 5946798
    Abstract: The method for manufacturing a core comprises the following steps: providing a strip made of an electrically conductive material, shaping the strip into a tube, the two edges of the strip being substantially in contact, and welding together the two edges of the tube-shaped strip, via laser welding, in order to form the core (1). The method is preferably performed continuously using a continuous strip of substantial length, in an advantageous manner, the shaped and welded tube undergoes calibration, then a surface treatment intended to promote the adhesion of the insulating material (6) so as to insulate the core with respect to the external conductor (8) of the coaxial cable.

  • Patent number: 5946884
    Abstract: A machine and method for wrapping cylindrical workpieces such as rolls of bathroom tissue and paper towel. The machine includes a workpiece infeed conveyor, a wrapping film feeder, a rotating carousel having a plurality of pockets, an oscillating exit conveyor, a discharge conveyor, and a sealing conveyor. A piece of wrapping film supplied by the wrapping film feeder is perforated and burst into a single sheet. The film sheet and a workpiece are directed into a pocket in the rotating carousel whereby the sheet is banded around the periphery of the workpiece by a clamping plate, underfolder plate, and brush secured by heat sealing the film sheet to itself. The banded workpieces are ejected from the rotating carousel onto an exit conveyor which passes the workpieces to a discharge conveyor which in turn conveys the workpieces through a sealing conveyor. Folding mechanisms for folding the wrapping film sheet extending beyond the ends of the workpieces are disclosed. The method of wrapping is also disclosed.

  • Patent number: 5944656
    Abstract: An endoscope contains no adhesives, epoxies, or other organic materials. The endoscope includes a set of lenses held in position by cylindrical spacers. A pair of windows seal the ends of the endoscope, and prevent the lenses and spacers from falling out. The windows are brazed to the endoscope. Due to the use of brazing, no adhesives are needed to hold the lenses or windows in place. Thus, one can sterilize the endoscope in the high temperature environment of an autoclave, without risking damage to the optical components. The brazing produces a hermetic seal which enables the endoscope to function properly in an environment of high temperature or high pressure, or in chemically abusive environments.
