Abstract: ANALYTICAL ELEMENT AND METHOD FOR COLORIMETRIC       DETERMINATION OF TOTAL CHOLESTEROL     Abstract of the Disclosure An analytical element is designed for the colorimetric determination of total cholesterol in aqueous liquids, such as biological fluids.  This element comprises an absorbent material and critical amounts of cholesterol ester hydrolase (from about 1500 to about 12,000 I.U./m2) and a nonionic surfactant (from about 5 and up to, but less than 11 g/m 2), The use of these ranges of reagents reduces the potential for interference by triglycerides present in a test sample.  Total cholesterol is determined with this element by detection of a color change resulting from a series of enzymatic reactions which produce hydrogen peroxide.

Abstract: ABSTRACT    A bellows-like hollow member (8) formed of gathered tubular sheathing material, for processing, especially as a peel-skin for the production of small sausages, produced as follows:  polypropylene with copolymers is extruded in a smooth foil of three inseparable layers, of which the middle layer is stronger and the two outside layers have a lower melting point.  The foil is then stretched to increase its strength, and is formed into a tube with a lengthwise seam (6) along its entire length, formed by overlapping and con-solidation of its lengthwise edges.  Finally, the tube is gathered bellows-like forming a plurality of folds (7) and forming hollow member (8), and is simultaneously rotated around its axis so that the lengthwise seam (6) produces a helical path.  The tubular sheathing which is obtained by this gathering is of inexpensive material, can be easily peeled from the boiled meat emulsion, can be used without difficulty in sausage machines, and is not sensitive during storage to moisture and high temperatures.

Abstract: ABSTRACT OF THE DISCLOSURE         ATTENUATOR CIRCUIT EMPLOYING BOOTSTRAPPING           When impedance elements such as FETs are used in attenuators, the elements have linear responses only when the signals attenuated are below certain signal levels.  When signal conditions causing the element to operate non-linearly are detected, bootstrapping is applied to reduce the voltage across the element so that the element will operate linearly.  The control signal at the gate of the element is then modified to compensate for the increase in effective impedance of the element caused by bootstrapping.  The improved attenuators are especially useful in signal compressors and expanders.

Abstract: ABSTRACT OF THE DISCLOSURE      Disclosed is a complementary vertical NPN and PNP pair having matched performance.  The PNP collector is located deep in an epitaxial layer overlying a semicon-ductor  substrate.   The junction  depths  and  surface concentrations of both emitters are quite similar; the junction depths and surface concentrations of bases of the  complementary  devices  are  also  similar  to each other.   The PNP and NPN emitters  are  provided with self-aligned  conductive  contacts.   A  high  dopant concentration equal to that in the emitters is provided in all contacts of the transistor elements to reduce the contact resistances.    Disclosed too is a process of forming the above structure.   Starting with  a  semiconductor  substrate having a blanket N+ NPN subcollector and an epitaxial layer thereon having first and second active regions, an NPN base precursor and PNP collector reach-through precursor are simultaneously implanted in the first and second active regions, respectively.  PNP collector is then formed in the second active region by implanting P type species to lodge them at the bottom the epitaxial layer.   PNP base precursor is then implanted in the surface region of the epitaxial layer in the second active region.  By annealing, the the NPN and PNP bases and PNP collector reach-through are obtained from their respective precursors.  A high-dopant concentration and shallow NPN emitter and low-resistance contact region for PNP base are simultaneously implanted.  PNP emitter and contact regions for PNP collector reach-through and NPN base  having  a  concentration  and  function  depth similar to those of the NPN emitter are simultaneously implanted.    Self-aligned conductive   contacts   are established with both emitters and all other transistor elements.
