Abstract: ABSTRACT OF THE DISCLOSURE      A seal section for a submersible pump assembly has multiple seal chambers, each with an independent bellows. The seal section is located between the motor and the pump, and receives a shaft driven by the motor.  At least one partition is located in the seal section, with the shaft sealingly passing through the partition.  The par-tition divides the motor and seal sections into a primary chamber and at least one secondary chamber.  A primary bellows is located in the primary chamber.  The bellows is in contact with well fluid on one side and lubricant of the pump assembly on the other side for equalizing pressure.  A secondary bellows is located in the seal sec-tion with one side in contact with the lubricant in the primary chamber and the other side in contact with the lubricant in the secondary chamber.  The secondary bellows equalizes the pressures between the two chambers.  A check valve in the partition allows fluid to flow from the pri-mary chamber to the secondary chamber for replenishment, but prevents fluid flow in the opposite direction.

The brazing foil, useful for brazing iron, nickel and cobalt base alloys, has a composition essentially of 1 to about 41 atom percent palladium, 0 to about 20 atom percent chromium, 11 to about 20 atom percent boron and the balance essentially nickel and incidental impurities. In addition to containing the foregoing elements within the above noted composition ranges, the composition must be such that the total of nickel, palladium and chromium ranges from about 80 to 89 atom percent and the total amount of boron constitutes the remainder that is 11 to 20 atom percent.  The ductile foil permits fabrica-tion of preforms of complex shapes and do not require binders or fluxes.

Abstract: ABSTRACT OF THE DISCLOSURE         A-influenza sub-unit vaccine is provided free from contaminants from A-influenza virus-containing allantoic fluid by a combination of selective membrane filtration and chemical splitting of the virus.  The allantoic fluid first is freed of undesired particulate matter dimensioned smaller and larger than the virus and also of undesired dissolved matter.  The virus then is chemically treated to split off the HA and NA units.  Thereafter, the residual virus body, undesired particulates of same particle size as the virus, and a sur-factant used in the chemical treatment are eliminated by selective membrane filtration.  The procedure is much less costly and simpler to effect than prior art procedures.

Title: Use of synthetic bifunctional ligand for the immunometric determination of the concentration ratio of two solutes

Abstract: Abstract The use of a synthetic bifunctional ligand for the immunometric determination of the concentration ratio of two solutes The specification describes an immunochemical method for detecting the fertile period of the menstrual cycle, by determining the ratio, in urine of the two hormonal metabolites oestrone-3-glucuronide (E13G) and pregane-diol-3-glucuronide (PD3G).  The method depends of deter-mining how an immunocomplex dissociates in the presence of the two metabolites.  The immunocomplex comprises a solid phase with antibodies to PD3G attached, and bifunctional ligand (E13G and PD3G both covalently bound to bovine serum albumin) bound to these antibodies, finally E13G antibodies are bound to the E13G moieties of the bifunctional ligand.        The immunocomplex is incubated with urine.  The meta-bolites in the urine compete for the antibodies so the immunocomplex partially dissociates.  The solid phase is washed and the number of exposed E13G moieties remaining depends on the ratio of E13G to PD3C in the urine.  These are determined with enzyme labelled E13G antibodies.

Inventor: GNEUSS DETLEF
IPC: B29C48/09

Granted: 1986-01-28
Abstract: Abstract of the Disclosure A ring nozzle for use with an extruder to continuously form a synthetic-resin tube has a substantially stationary back nozzle part having an axially forwardly directed front face and formed with an axially centered passage opening at the face.  This part is typically bolted over the outlet of the extruder.  An axially centered core rod is substantially fixed in the passage and extends axially forward past the front face.  This rod is also fixed in the extruder so that same can emit a hot and thick tubular strand of a plastified synthetic resin.  An annular and movable front nozzle part fits with spacing around the core forward of the front face and forms therewith an axially centered and forwardly open annular gap.  The thick tubular strand formed by the extruder becomes a thin-walled strand that emerges from the annular gap.  The axially confronting faces of the front and back mold parts have complementary part-spherical surfaces riding on each other and permitting the front nozzle part to tip limitedly on the back nozzle part, but having adjustment elements braced axially at three or more generally angularly equispaced locations between the back and front faces for tipping the front part on the back part and thereby adjusting the gap.  Biasing means urges the front part axially back against the adjustment elements.  This biasing means includes springs bearing axially back against the front part.

Abstract: ABSTRACT OF THE DISCLOSURE           The soluble fractions of facultative organisms grown on C1 compounds are capable of oxidizing organic compounds in the presence of a cofactor system compris-ing NADH2 or NADPH2.   The soluble fraction is obtained by aerobically growing the microorganism in a fermentor under continuous gassing with a mixture of a C1 compound and air and, initially, carbon dioxide before harvesting.          Preferably, the C1 compound is methane.     One facultative organism which is useful  in the microbiological oxidation of oxidizable organic substrates  is  Methylobacterium organophilum  (CRL.26, NRRL B-11,222).   This newly discovered and isolated methylotrophic microorganism strain and its natural and/or  artificial  mutants grow well  under  aerobic conditions in a culture medium in the presence of a C1 compound as the major carbon and energy source.

Resists used in the invention have chemically separated structures characterized by two types of regions of different chemical composition, which different types of regions are interspersed among each other.  Because the resists used in the present invention have chemically separated structures, anisotropic wet development of these resists is achievable with an appropriate bicomponent wet developer.  Consequently, after exposure, the image formed in a thin, upper layer of the resist is transferred with vertical walls through the thickness of the resist.
