Title: Phosphoric acid crystallization process
Inventor: WIEWIOROWSKI TADEUSZ KAROL
IPC: G01S15/58
Filed: 1986-04-30
Abstract: The present invention discloses a new method for obtaining a crystallized phosphoric acid of relatively high purity starting with conventional phosphoric acid. The new method is based on crystallization of orthophosphoric acid hemihydrate from the phosphoric acid. Massive nucleation which would lead to the formation of unprocessable masses is avoided in the new method by providing unusually large amounts of fine relatively pure seed crystals of orthophosphoric acid hemihydrate and operating the crystallization process under conditions which favor crystal growth on the seed crystals and disfavor the occurrence of secondary nucleation. To prevent the crystallizing magma from reaching a viscosity which would render further processing difficult the present invention provides for recycling raffinate in an amount suf­ficient to maintain the solids content of the crystallizing magma below about 40%.

Abstract: PCT No. PCT/GB87/00626 Sec. 371 Date Mar. 10, 1989 Sec. 102(e) Date Mar. 10, 1989 PCT Filed Sep. 7, 1987 PCT Pub. No. WO88/02111 PCT Pub. Date Mar. 24, 1988.A method for the rapid and sensitive analysis of heavy metal ores, especially those of gold and uranium, uses high-engery X-ray fluorescence spectroscopy. The invention is of particular interest for the measurement of samples from gold or bodies which typically have concentrations up to 10 ppm by mass. Preferred features include the use of an X-ray tube as a source, the counting of emitted fluorescence photons in energy bands selected to correlate with the characteristic x-ray fluorescence emissions of elements of interest, the excitement of the ore sample by irradiation with high energy bremsstrahlung radiation filtered through tin, the exploitation of polarization in analysis for uranium, the interposition of a platinum-group metal filter between the sample and the detector, and the use of high-purity germanium detectors. Techniques are described for the detection and elimination of inaccuracies due to the presence of certain interfering metals and correction for variations in sample density. Apparatus for use in the method of the invention is also disclosed and claimed.

Title: Megakaryocyte stimulatory factor
Inventor: ROSENBERG ROBERT D
IPC: C12P21/00
Filed: 1987-09-14
Abstract: A megakaryocyte stimulatory factor (MSF), purified to homogeneity, is an acidic protein (pI = 5.1) with an Mr 15,000 which stimulates PF4-like protein synthesis in rat promegakaryoblast cells by as much as 7-fold, and exhibits half-maximal activity at a concentration of 0.8 pM. MSF exhibits no biologic activity corresponding to other known hemopoietic growth factors, and appears to be specific for the megakaryocyte lineage. In the given examples, MSF was purified to homogeneity (as judged by SDS-PAGE and isoelectric focusing in the presence of 9.2 M urea) from serum-free conditioned medium obtained from cultured human embryonic kidney (HEK) cells, and to near homogeneity from thrombocytopenic plasma. The MSF is isolated by precipitating the MSF with ammonium sulfate at 80% saturation, removing insoluble, non-MSF material and applying the soluble protein to a WGA-Sepharose column, eluting the MSF protein with chitin oligosaccharides, applying the concentrated eluant containing MSF activity to a Biogel P200 column, and chromatographing the eluted MSF fractions on a TSK-G3000 HPLC size exclusion column.

Title: Corandomized fat compositions for infant formulas.
Inventor: LIEN ERIC LOUIS
IPC: A23C11/10
Filed: 1991-11-20
Abstract: The invention disclosed herein comprises fat compositions primarily for use in nutritionally complete infant formulas in which the constituent palmitic acid oils and lauric acid oils are corandomized. The invention additionally includes such corandomized fat compositions with medium-chain triglycerides added, particularly for use in nutritional products for preterm or low birthweight infants. Such corandomization of two or more oils yields a mixture of triglycerides having a substantially different chemical makeup than that of the native oils themselves or than the native oils when randomized individually. Corandomization of the palmitic acid oils and the lauric acid oils affords an economical means of providing a very highly absorbed fat composition.

Title: Control arrangement for a bus connection
Inventor: LEIMKOETTER ULRIGH
IPC: H04Q11/04
Filed: 1992-06-19
Abstract: Bus link control in a program-controlled communication system (K) with a program-controlled HDLC control structure under the requirements of a communication system equipped with only one processor. A link processing program module (PMSA) of the HDLC control structure of the bus link discriminates between necessary and time-uncritical system tasks (NS, NSZS, ZUS) during the processing. After conclusion of the system tasks necessary in every case (NS, NSZS), a    clock pulse counter (T) is interrogated, the counting pattern (Z) of which is short compared with the processing cycle (BZY). If the time value of the count (Z) of the clock pulse counter (T) is, for example, shorter than half the processing cycle (BZY), processing of time-uncritical system tasks (ZUS) is begun. <IMAGE>

Title: Slagline sleeve for submerged entry nozzle and composition therefor.
Inventor: HOOVER DONALD BRUCE
IPC: C04B35/634
Filed: 1997-07-08
Abstract: An improved submerged entry nozzle is provided which is useful in the casting of aluminum killed molten steel. The nozzle has an improved slagline sleeve or collar which surrounds the outer portion of the nozzle to protect it from corrosion during the casting process. The slagline sleeve is made from resin bonded zirconia/graphite which has been formulated so that upon curing of the resin to form resite, there is a reduction in the contractile tendency which results in a reduction in stress fracturing. The reduction of the contractile tendency and the resulting resistance to stress fracturing is achieved by adding an effective amount of calcium oxide to the resin-zirconia-graphite mixture which is used to form the sleeve.

IPC: B65D1/02
Filed: 1992-07-10
Granted: 1995-12-13
Abstract: The invention relates to improved child-resistant container closure assemblies comprising a container neck and a closure. The closure comprises an inner part (350) and an outer part (310), whereby the outer part (310) must be axially displaced relative to the inner part (350) by pressing down on the outer part (310) in order to unscrew the closure from its fully secured position on the container neck. The risk of accidental unscrewing of the closure without depression of the outer closure part is reduced by the provision of a first retaining means on the container neck and a second retaining means (358) on the inner closure part (350). The first and second retaining means engage at said fully secured position, and resist loosening of the closure from the fully secured position until a predetermined minimum release torque is applied to the inner closure part (350). <IMAGE>
