Patent DE-1963497-A1 (DE)
Title: Rolling of solid sections in four-high strands
Inventor: KLETZIN PETER DIPL-ING
IPC: B21B1/08
Filed: 1969-12-18
Abstract: Rolling method prevents the formation of cracks on the surface of the rolled stock, e.g. wire, and effects symmetrical rolling on both sides. The rolled stock is backward rolled from pass to pass while reducing the diagonal sections in all 4-high calibre sequences. The amount of reduction of the rolled sections increases with growing backward pass.

Patent DE-2231561-A1 (DE)
Title: Purification of methyl cyanacrylates - by crystallization to give better adhesive
Inventor: KAMLANDER LUDWIG DR
Filed: 1972-06-28
Abstract: Further purification of technically pure polymerizable methyl derivatives, partic alpha-cyanacrylic esters, consists of at least one crystallization at a temp. below 0 degree C. The technically pure product is cooled until crystals appear, and these are separated, before thawing, from the liquid which is rich in impurities. During each thawing stage, stabilizers and polymerization inhibitors are added to the crystalline mass. The crystallization is carried out in a cylindrical non-conducting column, containing inside a flexible polyethylene tube, around which is a metal coil vibrating in the direction of the axis of rotation. The space between the polyethylene tube and this column is filled with an inert liquid such as paraffin oil, connected to a pump which may vary the pressure of the oil. Adhesives made from the purified cyanacrylates have faster hardening properties and give stronger bonds than the untreated materials.

Title: Coke oven gas compression - with longer service periods by prior injection of cleaning agent surfactant and water
Inventor: GOBIET VIKTOR DR ING
IPC: C10K1/10
Filed: 1975-02-05
Abstract: In a coke oven compressor station consisting of a precompressor and an after compressor, a cleaning fluid is continuously or intermittently sprayed ahead of the compressors. This agent, a mineral oil/water emulsion, mixed with a surface tension reducing agent (pyridine/water), dissolves all impurities produced by the reaction of resinogenic components of crude benzole with H2S and/or nitric oxides. The service time of the compressor plant before it needs an overhaul can thereby be prolonged considerably. The output of the compressors can be stepped up to 15%. The gas ducts to the high-pressure coolers downstream of the compressors are kept clean. The appts. required is much less than that needed in the past.
