Patent DE-4142109-A1 (DE)
Inventor: BAUER ADOLF ING GRAD
IPC: B29C41/04
Filed: 1991-12-19
Abstract: In a device for producing moulded plastic foils by means of a moulding tool which can rotate about one or more axes (14, 15), in which a thermoplastic powder is melted in layers on the heated mould surface and after cooling can be removed from the mould walls in the form of a moulded plastic foil, the heating and cooling take place by means of fluid heating and cooling agents which can be fed alternately into a chamber (4) in the moulding tool. In order to compensate for the considerable thermal stresses between the housing walls (5) enclosing the chamber and the mould walls (2), there are stress-compensating convexities (6, 7) in the housing walls. The thermal stresses are primarily caused by the different materials of the mould and housing walls. The mould walls (2) consist of a galvano-material, e.g. a copper-nickel alloy, whereas the housing walls (5) are of ordinary sheet steel.

Patent DE-4204000-A1 (DE)
Inventor: SCHLASSE MANFRED
IPC: A01D34/13
Filed: 1992-02-12
Abstract: A process for manufacturing a blade (8) having at least one cutting edge (7) and being made of steel provides for a blade blank to be punched and this, in the region of the cutting edge (7) to be formed later, to be heated in the surface region and then to be quenched, and the cutting edge being produced on the blade blank by grinding. The blade blank is punched from a low-carbon steel which after heating and quenching attains a core hardness of from approximately 35 to 48 HRc. The blade blank, with its surface resulting after punching, is surface-treated thermochemically by the blade blank in the process being heated as a whole, by there being introduced by diffusion into the free surface of the blade blank at least carbon and/or nitrogen, and the blade blank being quenched, so that the blade blank simultaneously is tempered in its core and on its free surface is hardened, prior to the cutting edge (7) being produced by grinding of the cutting face (6). <IMAGE>

Title: Breathing mask for supplying oxygen@ enriched air to patient - also control supply of Carbon di:oxide
Inventor: ARDENNE MANFRED VON PROF DR
IPC: A61M16/00
Filed: 1992-03-13
Abstract: The supply of oxygen to the tissue of a patient is improved by increasing the quantity of C02 in the arteries of the human organs.

The mask is connected to a bag (13) which contains C02 which has been breathed out by the patient. This enables the breathing gas to be formed by a mixture of oxygen enriched air and C02 which enables sufficient C02 to be supplied to achieve a partial pressure of 60 mm Hg in the arterial blood. USE/ADVANTAGE - Supply of oxygen enriched air with controlled amounts of C02.

Title: Process for the spinning of staple fibres to form a yarn and apparatus for carrying out the process
Inventor: BRUNK NORBERT DR
IPC: D01H4/10
Filed: 1993-02-05
Abstract: In a process for the spinning of staple fibres to form a yarn, fibre material delivered in sliver form is opened into individual fibres and is fed, in a quantity corresponding to the subsequent yarn cross-section, into the interior of a hollow rotor. The fibres are fed to a frustoconical inner collecting surface approximately in the direction of rotation, the collecting surface moving at a circumferential speed which corresponds at least to the feed speed of the individual fibres. The collecting surface merges into a collecting groove, into which the fibres are transferred in the course of a revolution of less than 360@ and are bundled therein to form a closed composite fibre structure. At a predetermined circumferential point, the composite fibre structure is drawn off at a draw-off speed corresponding essentially to the circumferential speed of the collecting groove. During the draw-off, a twist is imparted to the composite fibre structure. The collecting surface is made impermeable to air and has a coefficient of friction of less than 0.35 in relation to the fibres.
