Inventor: POELLINGER NORBERT
IPC: A61K31/47
Filed: 1989-04-13
Granted: 1995-08-29
Abstract: Ciprofloxacin and related gyrase inhibitors are tolerated well if administered intramuscularly in the form of an aqueous suspension of the betaine form having an approximate neutral pH value or in the form of an oily suspension of the betaine or salts thereof. Oily suspensions which contain the active material in water-soluble form, eventually in form of the hydrochlorides, lactates, mesilates, methanesulfonates and other salts, are capable of releasing  the active compound very rapidly, particu-larly when the wettability of the oily carrier medium is in-creased by addition of interfacially surface active materials.

Abstract: A process for determining the genotype of an individual with respect to the alleles at the HLA DP locus involves obtaining a sample of nucleic acid from the individual and hybridizing the nucleic acids with a panel of probes specific for variant segments of DPalpha and DPbeta genes. Because the variation between DPbeta alleles is highlydispersed throughout the second exon of the DPbeta gene, the discovery of many different DPbeta alleles makes the process far more discriminating and informative than cellular, RFLP, or serological methods. The process can also be carried out on amplified nucleic acid produced by the polymerase chain reaction using primers specific for the second exon of the DPalpha and DPbeta genes. HLA DP DNA typing methods are useful in the prevention of graft rejection and host versus graft disease, in determining susceptibility to autoimmune diseases, in providing evidence concerning the derivation from an individual of forensic samples, and in paternity testing.

Abstract: ABSTRACT OF THE DISCLOSURE A plurality of thermoplastic sheets are laminated into a laminated assembly, which is them pressed into a lam-inated assembly.  First, the sheets to be laminated in one cycle are heated while the sheets are arranged in a juxta-posed relationship in the order in which they are to be laminated.  The heated sheets are penetrated with needles to detachably hold the sheets while keeping the sheets in the juxtaposed relationship.  A support member which supports the laminated assembly is moved below the sheets held and relatively to the sheets in a direction in which the sheets are arranged in the juxtaposed relationship, the sheets are released from the needles onto the support member to stack the sheets thereon into the laminated assembly while the support member is being moved relatively to the sheets.  The support is then delivered into a shaping die assembly.  The laminated assembly on the support member which has been delivered into the shaping die assembly is charged into a charging position in the shaping die assembly, and the sup-port member is removed from the shaping die assembly.  The laminated assembly is then pressed into a shaped product with the shaping die assembly after the laminated assembly has been charged into the charging position.

Abstract: A method and apparatus for minimizing the visual degradation of a typeface wherein the need for the manual input of skilled technicians is eliminated and the important visual components of each character and the relationship of the visual components of each character with the other characters of the typeface are preserved. The characters are analyzed to determine the visual components in the horizontal and vertical direction which comprise each character and the priority of adjustment. Using the visual components determined, starting with the highest priority component, the coordinates describing each character are adjusted according to rules which are dependent upon whether the strokes formed are oriented in the horizontal or vertical direction. The adjustment of the lower priority visual components isdependent on the previously aligned components. The important visual components in the diagonal direction are subsequently adjusted in accordance with similar sized visual components in the horizontal and vertical direction wherein the dimensions of the adjusted horizontal and vertical components are maintained.

Abstract: A process for the recovery of copper and zinc values from copper and zinc containing sulphidic ore includes subjecting ground ore to a flotation operation. An initial copper concentrate is floated in a first flotation step, and the initial copper concentrate is fed to a second flotation step to float a relatively zinc free copper concentrate. Remaining ore from the first flotation step is fed to a third flotation step to float an initial zinc concentrate, and remaining ore from the third flotation step is fed to a fourth flotation step to float a copper and zinc containing material. An intermediate concentrate containing from about 5 to about 25% copper and from about 2 to about 25% zinc, with a total of at least about 12% copper and zinc, is produced by selecting at least the remaining ore from the second flotation step, and a zinc concentrate containing at least about 20% zinc is produced by at least selecting a portion of the initial zinc concentrate.
