Title: Devices for the controlled release of active substances, as well as process for the preparation thereof
Inventor: DE HAAN PIETER
IPC: A61K9/20
Filed: 1986-03-12
Granted: 1990-02-06
Abstract: A B S T R A C T The invention relates to a device for the controlled release of one or more active ingredients to a liquid, particularly a controlled release pharmaceutical tablet obtained by compressing a mixture of two granulates in a weight ratio of 30:70 to 70:30, said granulates having particle sizes of 0.4-2.0 mm. One of the granulates, the restraining phase granulate, comprises one or more active ingredients dispersed in a matrix of an insoluble substance, and the other granulate, the housing phase granulate, comprises a soluble material and a penetration rate limiting material, one material optionally having both functions. In the compressed de-vice, the granulates form two distinct phases, each of which is continuous. The housing phase fills large continuous pores in the restraining phase. A zero-order release rate can be obtained with the devices.

Abstract: A double-stranded  cDNA molecule  which  includes  DNA encoding human manganese superoxide dismutase has been created. The sequence of one strand of a double-stranded DNA   molecule    which   encodes  human  manganese superoxide dismutase has been discovered. Such molecules may be introduced in prokaryotic, e.g., bacterial, or eucaryotic, e.g., yeast or mammalian, cells and the resulting cells cultured or grown under suitable conditions so as to produce human manganese superoxide dismutase, human manganese superoxide dismutase analogs or human manganese superoxide dismutase mutants which may then be recovered. By this invention, human manganese superoxide dismutase gene fragments from various plasmids may be ligated to yield a complete genomic human  manganese  superoxide  dismutase  gene  fragment. Human manganese superoxide dismutase, analogs,  or mutants  may  be  used  to  catalyze  the  reduction  of superoxide  radicals,  reduce reperfusion  injury, prolong the survival time of isolated organs, or treat inflammations.        The invention also concerns a method of producing enzy enzymatically active human manganese superoxide dismutase compounds in a bacterial cell which contains and is capable  of  expressing  a  DNA sequence  encoding  the superoxide dismutase compound by maintaining the bacterial cell under suitable conditions and in a suitable production medium. The production medium is supplemented with an amount of Mn++ so that the concentration of Mn++ in the medium is greater than about 2 ppm. Genomic manganese superoxide dismutase DNA should also be capable of expression in eucaryotic cells under suitable conditions.               This invention also concerns a method of recovering purified enzymatically active manganese superoxide dismutase, analogs or mutants from bacterial cells. It should also be possible to recover manganese SOD from genomic manganese superoxide dismutase DNA expressed in eucaryotic cells using similar methods.               The invention further concerns uses of the human manganese superoxide dismutase, human manganese superoxide dismutase analogs or human manganese superoxide dismutase mutants, various new analogs, compositions of the compounds and methods of treating various disorders using these compositions.

Abstract: Abstract of the Invention An optical fiber splice and the method of forming it are described wherein a hollow cylindrical glass member is provided, the member having a bore along the longitudinal  axis  thereof.   Fluid  at  a pressure  in excess of ambient pressure  is  provided to the bore while the member is subjected to localized heating of the member to the softening point of the glass.   In this manner, a bubble is formed within the member bore under the influence of said heating and pressure.  For more uniform bubbles, the member may be rotated about its  longitudinal axis while it  is subjected to said fluid  pressure  and  heating.   The  splice  member  is subsequently formed by severing the cylindrical member at the location of the bubbles.  Optical fibers may be inserted  into  the  ends  of  the  splicing member  and cemented in place.

Abstract: ABSTRACT          A clamping arrangement is provided that clamps a switch pole-unit (or portion thereof) to a support member.  In a preferred embodi-ment, the clamping arrangement includes a first member that functions as a pole-unit base to support the switch pole-unit, a second member, and facilities for clamping the first and second members about the support member.  The first member includes notches that each have a length that is greater than or equal to the dimension of a predetermined portion of the support member that is assembled to the first member.  The clamping arrangement  further  includes  provisions  operative  during  or  after assembly that apply a force to secure the support member in the notches so as to prevent any movement of the support member relative to the notches of the first member; e.g., by forcing the support member into engagement with a first end of each of the notches.  The force-applying provisions in one arrangement include tangs which extend from the first member and are positioned so as to extend adjacent to the second end of each of the notches.  The tangs are effective to accommodate a predeter-mined range of dimensions for the support member and also provide self-alignment of the clamping arrangement during assembly.  In a preferred arrangement, the second member also includes a notch that is dimensioned to accommodate a predetermined portion of the support member that is assembled to the second member.
