IPC: A61B5/0245
Filed: 1994-04-06
Abstract: Method for determining a dominant heart rate from a series of beat triggers representative of a mixed series of normal heart beats and non-arrhythmic actives, with the beat triggers being determined at a specific sampling rate defining sample intervals, comprising the steps of framing a window to include a portion of the series of beat triggers and to be beat-aligned with a first beat trigger and a last beat trigger, the window thereby defining a plurality of trigger intervals for respective adjacent beat triggers, with each trigger interval containing a plurality of the sample intervals existing between the respective adjacent beat triggers; summing the windowed sample intervals; for each of the trigger intervals, computing a weight factor based upon the ratio of the summed windowed sample intervals to the number of sample intervals within that trigger interval; grouping the weight factors; computing the percentage of the window that each group of weight factors constitutes to determine the dominant group containing the dominant beat triggers and analyzing the dominant beat triggers within the dominant group to determine the dominant heart rate.

Abstract: A cam is eccentrically journaled at one end of a compound archery bow and a pulley is journaled at the other end of the bow. A cable passes around the pulley to form a bowstring section and a second cable section, both sections forming a dual feed single cam compound bow. The amount of feed out to both ends of the bowstring is approximately the same. One embodiment of the cam provides a large radius cam groove and a smaller radius cam groove which are designed to synchronize the rate of cable feed out at both ends of the bowstring section during the drawing operation. An anchor cable is provided to tie the two limbs of the bow together during the flexing of the bow.

Title: Process for making thin, sealant-coated, fiber-reinforced gypsum panel and panel made thereby
Inventor: CHASE PETER D
IPC: C04B40/00
Filed: 1994-08-19
Abstract: A process for making a thin, sealant-coated, tire and indentation resistant gypsum panel from at least 2 homogeneous layers of fiber-reinforced gypsum. A layer of a mixture of cellulosic fibers moistened with water and an additive to restrict the adhesion of cellulosic fiber to one another, is deposited on at least two separate conveyors to form a fibrous matt on each conveyor and a layer of dry calcined gypsum containing set accelerator is deposited on the fibrous matt on each conveyor.     The deposits on each conveyor contain, on a dry weight basis, about 70% to about 90% by weight gypsum, about 10% to about 19% by weight cellulosic fiber and about 1% to about 9% by weight of combined additive and set accelerator. Each layer on each conveyor is directed to a mixing station to form a homogeneous layer, and the formed homogeneous layers on separate conveyors are placed atop one another on a single conveyor to form a combined homogeneous layer. The combined homogeneous layer is subjected to pressure (compressed) to form a pressed, homogeneous fiber-reinforced gypsum panel. A sufficient amount of water is added to the layer or layers to rehydrate the calcined gypsum.     The pressed, homogeneous fiber-reinforced gypsum panel is dried, and the surface of the dried panel is sealed with a wax-free, water resistant sealant. Sealant-coated, fire resistant, indentation resistant gypsum panels having a thickness of about 0.25 inch and having a density of about 60 to 80 lbs./ft.3 are made from 2 homogeneous layers of fiber-reinforced gypsum.

Title: Imageable articles having dye selective interlayers
Inventor: PREMENTINE GLENN S
IPC: G03C8/40
Filed: 1993-04-05
Abstract: Copolymers of acrylonitrile and vinylidene chloride are used as selective diffusion interlayers in dye-diffusive photothermographic imaging constructions. The interlayers have sufficient permeability to be useful for constructions in which cationic dyes must be diffused from an emulsion layer into an image-receiving layers, but have insufficient permeability to the unoxidized leuco dye precursor. Use of these interlayers in multicolor dye-diffusive imaging constructions increases image stability and color separation in the final image.

IPC: A61B19/00
Filed: 1994-05-11
Abstract: A trocar catheter (110) includes a trocar rod (121) having a stepped diameter distal end for use with a catheter having a stepped diameter lumen wherein the trocar (120) is inserted into the lumen (113) of the catheter and the trocar is used to incise a patient and install the catheter after which the trocar is removed from the lumen of the catheter. The distal end (130) of the trocar rod (121) is provided with a stepped coaxial bore (132) into which a piercing point rod, a spring (140) and a safety sleeve (144) are assembled. The piercing point rod (122) has a proximal small diameter portion (138) which is press fit into a correspondingly small diameter portion of the coaxial bore (132) in the distal end of the trocar rod (121). The spring (140) is carried on the small diameter portion of the piercing point rod (122) and biases the safety sleeve (144) in a distal direction. The distal end of the piercing point rod has a larger diameter portion (123) tapering to a piercing tip (125) and the safety sleeve has a stepped inner diameter which prevents it from moving beyond a predetermined distal position covering the piercing tip (125). The stepped coaxial bore (136) has a large diameter portion for receiving the safety sleeve when it is pressed proximally against the spring. A protrusion (150) on the distal outer surface of the safety sleeve (144) prevents the catheter (110) from accidentally slipping off the trocar (120).

Title: Methods for Repairing Pipe
Inventor: FAWLEY NORMAN C
IPC: F16L55/175
Filed: 1993-08-24
Abstract: In a method for reinforcing defective portions of a pipeline, the defective portions are identified by conventional techniques, soil is excavated from around the pipeline to expose the deteriorated portions, any corrosion protection material is removed and the surface of the pipeline is cleaned. Gouges, dents and corrosion pitting are filled with an uncured filler material and, while the filler material is in an uncured workable state, a plurality of convolutions of a high tensile strength material are wrapped around the defective portion of the pipeline with a layer of a curable adhesive applied between adjacent convolutions. The adhesive then cures to a strongly adhesive state and the filler material cures to a rigid state capable of transferring the fluid pressure load within the pipeline almost instantaneously to the reinforcement band. Optionally, a layer of adhesive may be applied between the pipeline surface and the first convolution of the reinforcement band, in which case the adhesive must be compatible with the filler material so that both materials are able to cure fully, and also compatible with any corrosion protection material remaining on the pipeline. The method may be employed to reinforce both straight and bent portions of a pipeline.
