Granted: 1993-06-29
Abstract: FLEXIBLE FILTER ELEMENT EMPLOYING FILTERING    SHEETS FORMED WITH BYPASS OPENINGS                          Abstract Disposable filter element, adapted for use in a high-pressure filter housing, has a plurality of layers of flexible filtering material, some layers being formed with openings through which a portion of the fluid can flow without being filtered, and at least one downstream layer of the filtering material being free from such openings. When all of the layers of filtering material have the same pore size, the total area of the openings in each layer is larger than that of the openings of any downstream layer. Each opening-containing layer of the filtering material removes part of the contaminant in the fluid.  Interposed between adjacent opening-containing filtering layers is a layer of flexible transport material, and there is a layer of flexible prefiltering material positioned upstream of said filtering layers.  The prefiltering material has a porosity to filter out from the fluid any particle that is substantially as large as the openings of the most upstream of the filtering layers to guard against an opening becoming blocked by such a particle.

Title: Variable transverse webber and method
Inventor: MARSHALL GERALD M
IPC: D04H1/72
Filed: 1988-09-20
Granted: 1993-01-12
Abstract: 46 ABSTRACT A web or structure is formed by feeding separate supplies of fibrous material into contact with two separate lickerins that are parallel to each other and rotated toward each other. The fibers from the two lickerins pass through a mixing zone and are accumulated on a moving conveying screen that is moved parallel to the axes of the lickerins. Segmented baffle plates may be inserted into the mixing zone to control the lateral or cross-sectional composition of a web formed by the fibers accumulated on the screen. A segmented feed may be used to advantageously deliver different fiber materials at different rates to each lickerin. Radially layered composite web structures having circular cross-sections may be formed with the same apparatus by forming the conveying screen into a U-shape and selectively controlling the air flow through the screen.

Title: Agents and procedures for provoking an immune response to gnrh and immuno sterilizing mammals
Inventor: SILVERSIDES DAVID W
IPC: A61K39/39
Filed: 1988-09-29
Granted: 1995-05-16
Abstract: A technique has been developed to cause a mammal to generate antibodies which will bind to its native GnRH thus suppressing the mammal's fertility. The technique involves vaccinating a mammal with a novel conjugate of an immuno stimulating carrier and a novel GnRH analogue.  The analogue is substantially identical to the natural GnRH which is common to all mammals except that one or more of the normally occurring amino acids of this decapeptide have been replaced by an amino acid with a more reactive side group.  A favored technique is to utilize an analogue containing cysteine which, of course, has as a sulfhydryl side group.  This analogue may then be conjugated to a large protein carrier using a heterobifunctional agent carrying a group reactive with carboxyl or amino groups and a group reactive with sulfhydryl groups.  This conjugate then forms the immunogen base for a vaccine which may also contain art recognized adjuvants.  The vaccine formulation is then administered in a manner which raises a substantial amount of antibodies which bind to native GnRH.  Injection in a manner which provides slow release to the circulatory system such as IP, IM or SC is favored.

Granted: 1994-02-22
Abstract: INVENTOR:  JOSEF MAUER  INVENTION: METHOD FOR PRODUCING TITANIUM DIOXIDE                  ABSTRACT OF THE DISCLOSURE             Titanium slag and ilmenite are subjected to a combined but separate treatment with sulphuric acid obtained by mixing different proportions of sulphuric acid having concentrations of about 98.5% by weight and about 85% by weight,  respectively.   The  reaction mixtures  have  a temperature  slightly  below  a  predetermined  starting temperature and the reactions are started by adding small quantities of superheated steam having a temperature above the predetermined starting temperature.  The thus obtained solutions are  separated  from the respective treatment residues and combined.  The combined solutions are further processed for obtaining titanium dioxide.  The mother liquor constitutes sulphuric acid of a concentration in the range of about 23% by weight and containing metal sulphates.  This mother  liquor  is  concentrated  to  a  sulphuric  acid concentration of approximately 85% by weight and recycled.     The obtained metal sulphates are roasted and the roast gases further processed to obtain highly concentrated sulphuric acid which is recycled to the titanium slag treatment whereas the excess recycled about 85% sulphuric acid constitutes the main component used for the ilmenite treatment.  The weak acid obtained from the mother liquor thus is almost entirely re-used in an economical manner.

Title: Non-reverting shigella live vaccines
Inventor: STOCKER BRUCE A D
IPC: C12R1/42
Filed: 1989-03-14
Granted: 1995-05-23
Abstract: Live vaccines are provided and methods for preparing the live vaccines for protection of a host from a pathogenic microorganism.  The vaccines are prepared by introducing at least one modification in a gene involved in at least one, normally at least two, biosynthetic pathways involving the production of products which are unlikely to be found in the disease susceptible host.  The modification results in a gene change which cannot be repaired by a single step, e.g. polynucleotide deletions and inversions.  Where the aro gene suffers such a change, the resultant auxotrophic mutants require aromatic amino acids, p-aminobenzoic acid and 2,3-dihydroxybenzoic acid or a highly concen-trated source of absorbable iron.  The auxotrophic mutations have substantially reduced or nonexistent virulence while retaining the desired immunogenicity to initiate the immunogenic response.  Various techniques can be employed for providing the desired change.

IPC: C30B33/00
Filed: 1989-06-07
Granted: 1993-08-24
Abstract: ABSTRACT OF THE DISCLOSURE     Disclosed herein is a method of manufacturing a diamond laser crystal having excellent laser efficiency.          First, a synthetic type Ib diamond containing at least 60 volume  percent of  a  (111)  plane  growth  sector  (43)  is prepared.  This synthetic diamond is thermally treated under high temperature/high pressure,  so that type Ib nitrogen contained in the synthetic diamond is converted to type IaA nitrogen.   Thereafter an electron beam is applied to the synthetic diamond in order to generate vacancies in the synthetic diamond.  Finally, annealing is performed on the synthetic diamond to form H3 centers by coupling type IaA nitrogen  contained  in  the  synthetic  diamond  with  the vacancies.  According to this method, the H3 centers can be formed in the synthetic type Ib diamond in high concentration, while formation of NV centers which become an obstacle to laser action can be suppressed.
