Abstract: A method and apparatus for monitoring and measuring the filter blood volume by dilution techniques in real time, wherein the filter may be in use or off line during the measurements. The system includes a method and apparatus for measuring or monitoring the volume of a blood side of a filter by employing one of a bolus in the blood side upstream of the filter; a change of the filtration rate in the filter; and a bolus on the dialysate side, wherein the filter blood volume is calculated from the obtained data.

Abstract: A conductive gasket for use in apparatus to block the exit or entry of electromagnetic interference (EMI) between adjacent metal surfaces of the apparatus. The gasket is formed at least in part by a polymeric film having an outward facing surface embossed so as to provide a plurality of peaks distributed over the surface. A metal is coated, by vapor deposition, onto the surface so as to over lie the peaks. This provides the film with a conductive surface. When located between adjacent metal surfaces, abrasion of the metal coating from the peaks over time does not adversely affect the conductive properties of the film surface. This is because the wearing away of the metal from the tops of the peaks exposes a cross section of the metal at the sides of the peaks, which remain in contact with the adjacent metal surfaces of the apparatus.

Abstract: A method for securing a counterweight guiding system in performance rigging in places of entertainment. An elongate guide rail has a cross-section which interlocks with a clip, the clip extending transversely beyond the guide. The guide rail is secured to a support by fastening the clip to the support, the guide itself not requiring any specific fastening points.

Abstract: A weatherstrip having a hard bearing layer with a surface coating for reducing sliding friction between the weatherstrip and a panel is disclosed. A body of the weatherstrip has a relatively low durometer and the bearing layer has a greater durometer, wherein an exposed surface of the bearing layer is covered with a coating, wherein the coating can include a multitude of particles.

Abstract: An apparatus for forming transitioned edges in patterns formed by a scanning laser in a dyed textile material is disclosed. The transition rate between the untreated material and the treated material is controlled by passing a scanning laser beam through a mask prior to the laser beam reaching a focal point. An apertured mask can be employed to control the transition rate, wherein the location of the aperture relative to the focal point of the laser beam and configuration of the aperture periphery are manipulated to effect the transition rate.

Abstract: The measurement of blood flow in a dialysis shunt is obtained by injection of an indicator material into a venous line leading from dialysis equipment to the shunt. The blood flow in an arterial line leading from the shunt at a location downstream of the venous line to the dialysis equipment is monitored by an arterial line sensor for the presence of the indicator material. A detector connected to the sensor provides a dilution curve in response to the presence of the indicator material and the blood flow in the shunt is calculated from the area under the dilution curve. The locations of the arterial and venous lines in the shunt can be reversed to obtain a measurement of blood recirculation from the venous line into the arterial line.

Abstract: An apparatus and method for determining scale in captured images is disclosed. The apparatus includes a rectangular and generally flat frame device for determining scale in captured image. The frame has measurement indicia located along the inside edges and alignment markers located along the outside edges. The preferred embodiment has one measurement scale on two sides of the frame with an origin located at the corner between them and a different scale on the remaining two sides with an origin located at the opposite interior angle of the frame. A method of using the frame in conjunction with a digital camera and a computer is also disclosed.

Abstract: A supplementary cargo carrier for a vehicle. The carrier includes a support-frame, a platform and support bars which can be pivoted relative to the platform. The support-frame can be removably attached to a trailer hitch. The carrier can have a variety of configurations depending on the intended application, the configurations being changeable by adjusting the support bars and by reversing the orientation of the platform relative to the support-frame.

Abstract: A weatherstrip having a migration inhibiting layer including a butyl based elastomer, wherein the butyl based elastomer can include a blend of a halogenated butyl and EPDM. The migration inhibiting layer can be located on at least one of a dense portion and an expanded portion of the weatherstrip and is selected to substantially preclude the passage of decomposition products, thereby reducing odor emanation from the strip and discoloration from staining materials. The migration inhibiting layer may also include coloring agents thereby providing a colored weatherstrip.

Abstract: A motorized display using piezoelectricity to impart motion to point-of-purchase displays or other items is disclosed. A quartz movement, otherwise used for rotary movement of anniversary clocks, is preferably used to rotate the display. According to preferred embodiments, the motor has a drive train including a drive shaft and a battery as a power source. The drive shaft rotates when the motor is powered, a holder for a sign or merchandise item is positioned on the end of the drive shaft exterior to the motor housing and may be removable from the drive shaft. The drive shaft may be positioned vertically, horizontally or diagonally depending on the type of display being used. The rotation of the drive shaft may be either continuous one way or a 360 degree two-way revolution.

Abstract: A long-life, low maintenance, bi-directional vane-type water pump has a high degree of symmetry and operates with equal efficiency in either direction. The axial position of the drive shaft is controlled to permit improved lubrication by the pumping fluid of component parts on which the drive shaft is journaled.

Abstract: A combination mailer and a pocket file is disclosed. The combination includes a first file panel and a second file panel foldably connected together along a first fold line. The second file panel is foldably connected to a first mailer panel along a second fold line. The second file panel includes a separation line intermediate the first fold line and the second fold line. A second mailer panel is foldably connected to the first mailer panel along a third fold line, whereon a closure flap is foldably connected to the second mailer panel along a closure fold line.

Abstract: Disclosed is a pressure relief valve for attachment to a closed vessel having an opening to vent gas and liquids from the housing should the internal housing pressure rise to unacceptable levels. The pressure relief valve includes a single gasket that seals between a valve disk and a collar disposed about the opening. The gasket is fixed to the collar by a single retaining ring and effects seals with the disk valve in two planes, one seal is in a plane generally parallel to the plane of the opening and a second seal is in a plane generally normal to the plane of the opening. Moreover, the second seal remains in tact for a short time after the first seal is broken to permit the rapid separation of the disk valve from the gasket to vent gas and liquids from the housing.
