Title: Plastic coating for metal pipes - applied in spray chambers and adjoining temp. balance chambers
Inventor: HAFERKAMP HEINZ PROF DR ING
IPC: B05D3/02
Filed: 1980-02-07
Abstract: Metal articles, e.g. large-dia. pipes, receive a continuous corrosion-resistant non-porous plastic coating by applying electrostatically charged plastic powder to a thickness of 5-50 mu to the preheated pipe in motion. In an adjoining temp. balance chamber, reflected heat maintains a temp. of 230-250 deg.C, with an additional heat input if necessary. The pipe velocity is designed to result in the solidification of the plastic at least in the metal-plastic boundary. This eliminates the formation of microcavities in the plastic coating, it improves the plastic-metal adhesion and increases the corrosion resistance against chemical attack.

Title: Prostaglandin detection in blood, tissue or amniotic fluid - by radio-, fluorescence- or enzyme-immunological assay after ultrafiltration to remove serum proteins
Inventor: GILAK ARMIN DIPL CHEM DR RER N
IPC: G01N33/88
Filed: 1980-04-24
Abstract: In a new procedure for detection of prostaglandins, prostaglandin detection by radio-, fluorescence- and/or enzyme-immunological methods is carried out with the aid of ultrafiltration. The new procedure is applicable to the detection of prostaglandins in tissues, amniotic fluid, plasma and serum. Typically, a 3 ml. portion of the fluid to be examined is placed in a membrane filter with a pore size such that all serum proteins are retained. The ultrafiltrate is a protein-free soln. in which prostaglandins can easily be determined by usual immunological methods. Before or after the ultrafiltration, all fatty acids and interfering substances can be removed by washing with Et2O. Ultrafiltration gives a simple method for sepg. serum proteins from prostaglandins and of thus increasing the sensitivity and accuracy of the determination.

Title: Laminated core assembly for power transformers - has regular polygonal cross-section built up from quadrilateral packets of identical strips
Inventor: ANTIPOV VLADIMIR IVANOVIC
IPC: H01F27/245
Filed: 1980-12-10
Abstract: The core assembly system is applicable to reactors. The object is to achieve a space factor of at least 90% without the need for many different widths of core plate. A satisfactory construction is achieved using a single width of strip. Packets of four sided cross section with various acute angles are made from these strips of core steel. These packets are then assembled into a core limb. To achieve the minimum required space factor the limb has to have a regular octagonal cross section. Higher space factors are possible using assemblies giving polygons with a larger, but still even, number of sides. The requirements are that the individual packets are quadrilaterals with an acute angle which is a multiple of a coefficient dependent upon the number of sides on the core assembly polygon. If n is a multiple of 4 there will be n/4 packets with a square cross section.
