Title: Clamping arrgmt. for hydraulically driven shears - uses two beams to cut rod and sheet material during same stroke
Inventor: PEDDINGHAUS ROLF
IPC: B23D33/08
Filed: 1975-07-24
Abstract: The work cylinder (50) for the cutter slide is mounted in the machine frame. The rod material and the sheet material which is to be cut are clamped down, one above the other, in the path of the shear by means of two beams (12, 16).

Title: Polycrystalline diamond body prodn. - by epitaxially forming diamond-graphite coat on particles and sintering at high temp. and press.
Inventor: FEDOSEJEV DMITRIJ VALERIANOVIT
IPC: B01J3/06
Filed: 1975-07-28
Abstract: Prodn. of polycrystalline diamond bodies by coating individual diamond particles with graphite, and sintering a suitable shaped agglomerate under pressure whereby the graphitic domains are converted into the diamond structure. The diamond-graphite coating is formed on the particles by epitaxial deposition. The subsequent heating and compressing of the agglomerate results in the formation of a strong compact body free of graphitic inclusions. The epitaxial deposition takes place in a stream of a carbon-contg. gas. The gas stream is stopped before a purely graphitic surface layer is formed. The initial deposit has the diamond structure; then a mixed layer is formed; and finally a purely graphitic structure. These bodies withstand dynamic loading, so that they can be used as drill heads, cutting edges of metal-working tools, metal wire-drawing dies, etc. The starting material may contain even very small particles (1 mu), in contrast to the known process.

Title: Gasifying fluids e.g. sewage, biochemical effluents, etc. - using submerged rotor having highly efficient energy to depth ratio
Inventor: POEPEL FRANZ PROF DR ING HABIL
IPC: B01F3/04
Filed: 1975-12-30
Abstract: An insulation for gasifying fluids has a fully submerged, driven, propellent rotor. To the upper surface of the rotor, a gas, pref. air is fed via a down tube, while the surrounding fluid is picked up by the rotor undersurface, and dispersed outwards mixed with the air. The rotor acts as a double flow pump or fan wheel with vanes on both sides of the hub for air and fluid. The vanes extend beyond the circumference of the hub, above and below, in line with each other. They have as large as possible a dia. from tip to tip, to ensure that at the speed of revolution decide, a circumferential speed of 40 m/s will not be exceeded. The axial height of the vanes is pref. 3.5 cm. In contrast to conventional aerators working with surface agitators, the aerating equipment is totally submerged so that contact between the air and the fluid is the maximum possible. Its greater efficiency is reflected in a considerably reduction of the ratio of energy consumed to depth of submersion.
