Title: Method for carrying out hemodynamic measurements on a  patient and flow-directed balloon catheter used for this
Inventor: HEUVELMANS JOANNES H A
IPC: A61B5/0215
Filed: 1988-06-28
Granted: 1994-11-29
Abstract: A method for carrying out hemodynamic measurements on a patient, using a flow-directed balloon catheter, which is connected to a measuring unit and is at least provided with a distal measuring lumen and a balloon-inflating lumen, comprising the steps of inserting the catheter by way of a suitable vein and further by way of the right atrium and ventricle into the pulmonary artery until the distal end with the inflated balloon in wedge position is stuck in a branch thereof and closes off the latter. A proximal measuring lumen is provided a few centimetres apart from the distal measuring lumen. Then the pulmonary arterial pressure (PAP) is measured, as long as the catheter has not yet arrived in the wedge position, via both the proximal and distal measuring lumina and the two relevant, virtually identical pressure curves are simultaneously recorded.          In the wedge position of the catheter with the balloon inflated, the pulmonary arterial pressure (PAP) and the pulmonary capillary wedge pressure (PCWP) via both said measuring lumina are measured respectively.            A flow-directed balloon catheter for hemodynamic measurements for use with the above method, said catheter being provided with a distal measuring lumen, a balloon-inflating lumen, and a proximal measuring lumen a few centimetres apart from the distal measuring lumen.

Granted: 1991-12-10
Abstract: Abstract of the Disclosure Coacting die cylinders with one cylinder having a cutting blade and the other other cylinder an anvil surface which when rotating cooperate to cut a blank from a web of low density material.  The blade and the anvil surface are tapered in opposite axial directions so that the clearance between them can be readily varied and adjusted by moving the cylinders axially relative to each other.  Preferably, the cylinders each have a pair of cylindrical bearers which are in contact and rolling engagement with  each other when  the cylinders are operating to cut a web of material.   The die cylinders are journaled in bearing assemblies carried by the cylinders and removably received in the stand to facilitate easy removal and installation of the die cylinders when desired.

Abstract: CALCIUM-SUPPLEMENTED BEVERAGES AND BEVERAGE CONCENTRATES CONTAINING LOW LEVELS OF SULFATE                    ABSTRACT OF THE DISCLOSURE    Beverages and beverage concentrates nutritionally supple-mented with significant levels of solubilized calcium and containing low levels of sulfate, preferably in combination with low levels of chloride, are disclosed. These beverages and concentrates also contain specified levels of edible acids selected from phosphoric acid, citric acid, malic acid, fumaric acid, adipic acid, gluconic acid, and lactic acid, as well as mixtures of these acids. The particular acid systems are selected to provide the desired flavor and sourness character for the beverages and concentrates. Inclusion of low levels of sulfate/chloride in these beverages and concentrates provides a quicker onset of sourness, prevents or reduces aftertaste effects and improves the solubility of the calcium, particularly when high levels of phosphoric acid or citric acid are used. Inclusion of sulfate/chloride also prevents or reduces the precipitation and deposition of calcium salts on equipment surfaces during the pasteurization or sterilization of calcium-containing fruit juice beverages.

Title: Z-buffer allocated for window identification
Inventor: PRIEM CURTIS
IPC: G06F3/048
Filed: 1989-01-25
Granted: 1993-01-05
Abstract: ABSTRACT OF THE DISCLOSURE The present invention discloses apparatus and methods for displaying two and three dimensional graphics within a plurality of windows on a display system. The display system of the present invention includes a central processing unit (CPU) which provides RGB data to a bit-mapped display memory coupled to a cathode ray tube (CRT) display. A Z-buffer memory is provided with a Z-value for each RGB data point corresponding to a point on the object to be displayed. The Z-buffer is organized such that the value of the entire n bit buffer (0 through 2n-1) identifies the window in whichthe graphics and/or text is displayed. For windows in which only two dimensionally (2D) graphics/text is displayed, the Z-value is the same for both the window and each RGB point of the image. For windows which display three dimensional (3D) graphics, a range of Z-values for the buffer arc provided which define the window boundaries. Images to be displayed within a 3D window must have Z-values which fall within the particular window's Z-value range. Within each window traditional Z-buffering techniques are utilized to provide hidden surface elimination. The present invention also permits the use of hither and yon planes to selectively view cross-sections of objects within a 3D window.

Abstract: ABSTRACT OF THE DISCLOSURE           A microstrip phase scan antenna array is provided having a columnar array of microstrip radiating patches mounted on a dielectric substrate.  Each column of the array is fed by a separate variable, reciprocal ferrite rod phase shifter which is mounted on the substrate and is coupled to the column which it controls and to a source of millimetre wave energy by microstrip to dielectric waveguide transitions.  Each of the phase shifters is controlled by a helical biasing coil surrounding the ferrite rod.  All of the biasing coils are serially interconnected by a single scanning control drive wire and the numbers of turns of the coils are related to each other by an arithmetic progression in which the number of turns of a particular biasing coil differs from the number of turns of the adjacent biasing  coil in the sequence of biasing coils controlling the array by a constant amount.

Abstract: TITLE:  SCAVENGING MEDICAL HOOD                  ABSTRACT OF THE DISCLOSURE    A scavenging medical hood includes a hood for fitting over the head of a patient.   A gas inlet port leads to the interior of the hood for supplying the interior of the hood with an  appropriate respiratory gas and an  aerosolized medicinal agent contained within that respiratory gas.  A gas outlet connects between the  interior of the hood and the ambient air for discharge of gas from the interior of the hood including any residual aerosolized medicinal agent remaining in that discharged gas.  A vacuum port is located adjacent to the gas outlet.  A vacuum is applied to the vacuum port via a suitable motorized vacuum source.   Vacuum at the vacuum port aspirates gas from the area of the gas outlet to aspirate respiratory gas,  residual aerosolized medicinal agent still suspended in the respiratory gas and ambient air from the vicinity of the gas outlet into the vacuum port.   A filter located in the vacuum line serves to filter out the residual aerosolized medicinal agent from the aspirate in the gas line.

Abstract: Abstract of the Disclosure A repertory telephone dialer includes a memory for storing two telephone numbers and one telephone call payment number. Activation of a switch on the dialer causes the first telephone number to be dialed; thereafter, the dialer responds to a Calling Card Service-Prompt Tone by transmitting the call payment number. The call payment number corresponds to a credit card number of the party to be billed for the call. The dialer is constructed as an adjunct device that connects to an existing telephone set by merely rearranging cords. Included on the front surface of the dialer is a recessed area that accommodates a photograph or graphic rendering of the party whose telephone number is dialed and who typically makes payment for the call. Activation of another switch on the dialer inhibits the remote billing feature by causing the second telephone number to be dialed.
