Title: Method and apparatus for on-line filtration removal  of macromolecules from a physiological fluid
Inventor: MALCHESKY PAUL S
IPC: A61M1/38

Granted: 1984-10-23
Abstract: METHOD AND APPARATUS FOR ON-LINE FILTRATION REMOVAL     OF MACROMOLECULES FROM A PHYSIOLOGICAL FLUID          ABSTRACT OF THE INVENTION An on-line filtration system for the removal of macromolecules greater than 70,000 mol. wt. from a physio-logical solution, such as blood, in the therapeutic treat-ment of various disease states.  For blood, the plasma (which contains the macromolecules) is separated continu-ously from the blood using a first membrane filter with a membrane porosity of nominally 0.2 to 1.0 micron.  The separated plasma is then continuously filtered in a physi-ological temperature state or a cooled state through a second membrane filter with a membrane porosity of nomi-nally 0.01 to 0.2 micron, which retains the macromolecules. In the cooled state, separation of the macromolecules is effected more efficiently than could be done in the non-cooled state.  The treated plasma (macromolecules removed) is then reunited with the blood flow coming from the first plasma filter and returned to the patient.  The blood flow and filtration processes are generally continuous.  Suit-able agent(s) may be added to the separated plasma to promote formation of macromolecules.

Abstract: ABSTRACT OF THE DISCLOSURE Groups of juxtaposed slot nozzles are subject to the action of the same or different melts for producing thin metal strips or foils with a considerable width. The melts are applied as a closed pool to a moving cooler surface, e.g. a rotating drum, where the pool is solidified to a closed metal strip. These groups, which are staggered in the direction of movement of the cooler surface, can be subject to the action of different melts, so that a metal strip is obtained with juxtaposed and sharply defined regions with different characteristics. It is possible to produce amorphous or mixed amorphous/crystalline, or solely crystalline material structures. Alter-natively, by producing different cooling capacities on different surface areas, or by different structuring of different surface areas, it is possible to influence the solidification process of the melt on the cooler surface in such a way that within the strips or foils obtained) there are adjacent regions having different metallic and/or geometrical structures. Through the geometrical configuration of the cooler surface, it is possible to produce foils with a structured surface or with shape-limited individual regions, which permits the mass production of small parts from sheet or strip material.

Abstract: Abstract of the Disclosure An x-y position detector is shown which comprises a pen and contact plate with a resistive layer formed thereon.  Point electrodes are provided on the four sides of the resistive layer.       The materials of the resistive layer and the pen are selected such that the pen is in reliable galvanic contact with the resistive layer.  The resistive layer is hard and smooth, and permits easy motion of the pen.        The resistive layer consists of carrier particles with a hardness of between 5 and 9 on the Mohs hardness scale, pyrolytically coated with carbon and embedded in a binder whereby the resistive layer is hard and enables easy motion of the pen. The surface on which the pen moves is formed by molding the resistive material on a smooth intermediate substrate.

Abstract: ABSTRACT          DC stabilization system for a color TV receiver includes three control loops, each including a keyed comparator for comparing a respectively different one of a set of blue, green and red color signals with a common reference voltage during keying periods determined by line rate keying of "backporch" timing pulses.  The output of the keyed comparator responding to the blue signal adjusts the DC level of a luminance signal component used in color signal formation.  The output of the keyed comparator responding to the red signal adjusts the DC level of an I color-difference signal component used for color signal formation.  The output of the keyed comparator responding to the green signal adjusts the DC level of a Q color-difference signal used for color signal formation.          The line rate keying pulse source is subject to field-rate blanking to preclude comparator keying during significant portion of received signal's vertical sync interval.
