Title: Cooling device for extruded preform for blow moulding - has ring die with two annular distribution chambers linked by throttling gap and feeds cool air via throttle nozzle to preform
Inventor: EFFENBERGER ALFRED
IPC: B29C48/09
Filed: 1989-10-13
Abstract: The invention relates to a cooling device for an extruded tube which is subsequently blow moulded. The extruded preform hangs from a die and is cooled over a section of the length and around the whole circumference by a gas. Cooling of the outer surface allows preforms of relatively long lengths and constant thickness to be extruded. Cooling is achieved by a ring-shaped nozzle having two ring-shaped distribution channels linked to each other by a ring throttling gap. Gas from the second distribution channel passes through a further throttling nozzle and reaches the tubular preform surface where it flows through an annular gap between preform and outer pipe. USE/ADVANTAGE - In continuous or semi-continuous extrusion blow moulding. Even polymers such as PET, which permit only certain lengths of preform to be produced, can be used.

Title: Determn. of alkaline phosphatase in cells - by incubating with aromatic phosphate ester and diazonium salt, azo coupling the alcohol formed, dissolving dye from cell membrane, and measuring extinction
Inventor: SCHMIDT REGINE DR
IPC: C12Q1/42
Filed: 1991-05-29
Abstract: A process for the determination of alkaline phosphatase in cells comprises incubating the cells with an alkaline soln. of an aromatic phosphoric acid ester and a diazonium salt and converting the aromatic alcohol formed by the action of the alkaline phosphatase on the phosphoric acid ester into an azo cpd. by azo coupling with the diazonium salt. The azo cpd. which is fixed in the membrane is selectively dissolved out of the cell membrane using an organic solvent and determined quantitatively by measuring the extinction of the resulting organic soln. at a suitable wavelength and comparing to a corresponding zero value and the amt. and activity of the alkaline phosphatase determined quantitatively from the concn. or amt. of the azo cpd. formed and from the no. of cells investigated. USE/ADVANTAGE - The process can be used in medical diagnoses e.g. in the detection of liver diseases and diseases of the skeleton and in the determination of various types of cells e.g. osteoblasts or bone marrow cells. Increased alkaline phosphatase levels can be used to diagnose certain illnesses and are observed e.g. in Morbus Paget, osteosarcomas, jaundice, hepatitis and similar diseases. A wide range of cell samples can be used; esp. good results being obtd. with tissue obtd. e.g. in histology, cell smears and cell cultures. The cells are not destroyed in the process so the same cell sample can be used for morphological tests other than the alkaline phosphatase test. As intact cells are used, there are no costly, labour intensive work up and sepn. processes of isoenzymes and the process need not be carried out by highly skilled personnel. The process can also be used for substance screening in toxicology and pharmacology.
