Title: Gene clone for the human dopamine d1 receptor
Inventor: SEEMAN PHILIP
IPC: C12N15/12
Filed: 1990-08-27
Abstract: Form 24 [GENE CLONE FOR THE HUMAN DOPAMINE D1 RECEPTOR]            ABSTRACT   Biological receptors for dopamine are presently classified into two types, termed D1 and D2. The D1 receptor is defined as the protein on which dopamine acts to stimulate the enzyme adenylate cyclase; this latter enzyme is inhibited when dopamine acts on D2. D1 and D2 are targets of drug therapy in psychomotor illnesses such as Parkinson's disease, schizophrenia, and drug addiction. We here report and patent the D1 receptor gene and its sequence of nucleotide bases. The D1 protein which is made by this gene has 446 amino acids. The D1 gene contains regions {susceptible to restriction enzymes, particularly EcoR1}which differ between humans, making this D1 gene helpful for future studies attempting to link or associate the gene with various human diseases.

Title: Method of electrode fabrication for solid oxide electrochemical cells
Inventor: JENSEN RUSSELL R
IPC: H01M8/12
Filed: 1991-01-22
Abstract: A process for fabricating cermet electrodes for solid oxide electrochemical cells by sintering is disclosed. First, a porous metal electrode is fabricated on a solid oxide cell, such as a fuel cell by, for example, sintering, and is then infiltrated with a high volume fraction stabilized zirconia suspension. A second sintering step is used to sinter the infiltrated zirconia to a high density in order to more securely attach the electrode to the solid oxide electrolyte of the cell. High performance fuel electrodes can be obtained with this process. Further electrode performance enhancement may be achieved if stabilized zirconia doped with cerium oxide, chromium oxide, titanium oxide, and/or praseodymium oxide for electronic conduction is used.

Inventor: AGRAWAL RAKESH
IPC: F25J3/04

Abstract: ABSTRACT The present invention relates to an improvement for the production of argon from cryogenic air separation processes.  In particular, the improvement provides a better method of thermally linking the top of the crude argon column with the low pressure column.  In the improvement, the argon-rich, overhead vapor from the top of the crude argon column is condensed in a boiler/condenser by indirect heat exchange against liquid descending the low pressure column; a portion of the condensed argon-rich, overhead vapor is returned to the top of the crude argon column to provide reflux.  The most suitable location for such boiler/condenser is as an intermediate boiler/condenser in the low pressure column, particularly, the section of the low pressure column bounded by the feed point of the crude liquid oxygen from the bottom of the high pressure column and the vapor feed draw line for the crude argon column wherein an adequate temperature difference exists between the descending liquid and the condensing argon.
