Title: Drill pipes and casings utilizing multi-conduit tubulars
Inventor: CURLETT HARRY B
IPC: E21B21/08
Filed: 1987-05-06
Granted: 1993-06-22
Abstract: Abstract:          This invention describes a tubular for use in well drilling and production.  The tubular is comprised of an elongated pipe with ends adapted to be connected with ends of other similar drill pipes.  A plurality of independent arcuately spaced conduits are spaced uniformly from one end of the pipe to the other end.  This allows a plurality of different fluids to be communicated to and from the well.  The method of connecting the tubulars together to provide a transmission path involves placing one electrical wire in one conduit of the tubular, then terminating each wire with an electrical connector fixed in a respective opening of the conduit, then sealing the end of each tubular around the respective conduit opening and finally connecting the plurality of tubulars and respective connectors together without respective rotational movement between the tubular.

Title: Antiestrogenic hydrazones
Inventor: MORGAN LEE R
IPC: A61K31/15
Filed: 1987-06-30
Granted: 1994-08-16
Abstract: ANTIESTROGENIC HYDRAZONES                   ABSTRACT Azido-, 4-nitro and 2,4-dinitrophenylhydrazones as well as 4,4'-dihydroxybenzophenone-hydrazone are disclosed which have antiestrogenic activity useful in treating estrogen-requiring tumor cells.  The described hydrazones bind to estrogen receptors in the cytoplasm of tumor cells.  The azido-, 4-nitro- and 2,4-dinitrophenyl branches of the molecules appear to bind to the receptors and prevent translocation of estrogenic information into the nucleus, thereby blocking the synthesis of necessary macromolecules such as proteins. Absence of geometric isomerization from antiestrogenic to estrogenic forms of the drug minimizes estrogenic side effects.

Title: Method of producing a layer of superconductive oxide, and apparatus and systems comprising a layer produced by the method
Inventor: RICE CATHERINE E
IPC: H01L39/24
Filed: 1988-04-07
Granted: 1993-11-02
Abstract: Abstract:         Disclosed is a method for forming a superconductive oxide layer on a substrate.  The method comprises applying a precursor solution to a major surface of the substrate such that a metal-containing layer is formed on the surface, and heat treating the substrate/layer combination such that at least a substantial portion of the layer material is transformed into superconductive oxide.  Exemplarily, the precursor solution is formed by dissolving Ba-, Y-, and Cu- containing compounds in acetic acid and water, spinning the solution on a MgO substrate, driving off unwanted constituents of the resulting layer at 400°C, heating the combination to about 830°C in O2 such that the (perovskite) phase that is associated with superconductivity in YBa2Cu3O7 is formed, and oxygenating the layer at about 400°C in O2.   The method is broadly applicable, but requires choice of a substrate that is substantially inert under the processing conditions, or provision of an inert barrier layer between a substrate and the superconductive layer thereon.  Exemplarily, Au, Ag, ZrO2, MgO and SrTiO3 are substantially inert with respect to YBa2Cu3O7.

Title: Thin film device for an ink jet printhead and process  for manufacturing same
Inventor: ADEN JAMES S
IPC: H01L49/02
Filed: 1988-07-14
Granted: 1992-06-02
Abstract: Abstract A process for manufacturing a thin film resistor substrate useful, for example, in fabricating an ink jet printhead, wherein discontinuous strips of conductive material are initially patterned on the surface of a resistive layer.  These strips are formed using a first series of masking and etching steps to define an "X" dimension of a resistive heater element.  Then, the conductive strips and resistive material therebetween are completely masked in preparation for a subsequent, second etching step used to remove the exposed portions of the resistive layer and thereby define a "Y" dimension of the resistive heater element.  These steps leave smooth contours, good step coverage and high quality bevelled edges of the thus defined conductive and resistive layers.  These layers are now ready for subsequent passivation layer, barrier layer and orifice plate deposition processes to complete a thin film printhead for use in an ink jet printer.
