Title: Process for the size fractionation of linear polymers by liquid-liquid chromatography
Inventor: MUELLER WERNER PROF DIPL CHEM
IPC: G01N30/34
Filed: 1982-07-13
Abstract: The invention relates to a process for the size fractionation of macromolecular substances by liquid-liquid chromatography using the two-phase system formed from polyethylene glycol and dextran, with the lower dextran-rich phase as the stationary phase, and gradient elution of the polymer fractions, and is characterised in that a phase ratio (ratio between the mobile phase and the stationary phase) of from 1.10 to 1.70 and a temperature of from 30 to 40 DEG C are used. The support used for the stationary phase is, for example, cellulose.
Patent DE-3227936-A1 (DE)
Title: Folding shutter
Inventor: STROHMAIER DIETRICH A DIPL ING
IPC: E05F11/36
Filed: 1982-07-27
Abstract: To prevent heat losses, the shutter is mounted in a fixed frame, sealed by flexible seals against the frame and heat-insulated. During the warm season, the sealing and heat insulation are circumvented by partly open positions or removable inserts. The shutter is operated by means of suitable drives from inside, by hand or motor - the latter also under remote control. The fixed frame is used for the purpose of locking the shutter and, for example, making break-ins more difficult. Accordingly, the outer skin of the shutter may also be designed in such a way that it withstands external attacks and loads.

Patent DE-3236956-A1 (DE)
Inventor: ZENKER WALTER
IPC: F16H3/08
Filed: 1982-10-06
Abstract: A change-speed gear in group-type construction with a main gear-shifting mechanism and a group gearing connected thereto. A primary shaft drives a main shaft selectively via gears of an intermediate shaft or by direct coupling of the primary shaft and the main shaft and at different speeds. The gears of the main shaft furthermore mesh with gears of the group stages of the group gearing; these latter gears are freely rotatably mounted on an output shaft and can be coupled therewith. To eliminate components and to provide a compact change-speed gear, one gear of the intermediate shaft, in addition to its function as shifting gear of the main gear-shifting mechanism, at the same times performs the function of a reversing gear for the reverse group of the group gearing.

Title: Method and device for manufacturing shoes
Inventor: MARAZZINI SEVERINO
IPC: B29D35/06
Filed: 1982-11-18
Abstract: The method for manufacturing shoes aims at simplification and acceleration and to this end envisages that the sole is moulded in a casting or injection moulding process and the upper material (22) is held on the sole contour during the solidification of the cast material so that both materials bond. Manufacture of the sole and its connection to the upper material take place simultaneously. The device intended for implementation of the method consists of a matrix (10) which serves a support post, two mould halves (12, 18) for the sole which are in each case movable between an open position and a working position, and holding members (34) for the upper material. By means of these members, the edge parts (22a, 22b) of the upper material (22) are held at the desired points on the sole contour and thus delimit, together with the two mould halves (12, 18), the hollow mould (14) for the sole. <IMAGE>

Abstract: A pulverised coal burner of small to medium output is proposed, having a fuel nozzle which opens into a combustion chamber and is fed with pulverised coal pneumatically with a carrier gas, and having a pilot burner which can be switched on and off, permitting a complete combustion of the pulverised coal place the burner nozzle concentrically surrounds the pilot burner or the pilot flame, and is constructed as an annular gap nozzle, which has injector openings within the combustion space on the peripheral side for sucking in hot combustion gases. The mixture of pulverised coal and carrier gas is preferably preheated to about 600 DEG C by heat exchange at the outer casing of the burner pipe, and is then given a preheating temperature of 800-1000 DEG C, at which it flows into the combustion chamber, in the injector-like annular nozzle due to the recirculation of combustion gases through the injector openings in the annular gap nozzle.

Patent DE-3318601-A1 (DE)
Title: Combined gas turbine-steam turbine plant and/or combined gas turbine steam generator plant
Inventor: WIESER RUDOLF DR
IPC: F01K23/06
Filed: 1983-05-21
Abstract: The invention relates to the special connection of a combined gas turbine-steam turbine plant and/or a combined gas turbine steam generator plant in which the combustion air drawn in by the compressor of the gas turbine is preheated by flue gases or steam or hot feed water. This connection is particularly suitable for the conversion of existing steam power plants, which in the process retain their original high efficiency and the construction of which has to be modified only a little. This is advantageous, inter alia, when the gas turbine is omitted from the converted, combined gas turbine-steam turbine plant and the steam power plant has again to be operated on its own for a certain period of time. The new circuit is particularly advantageous when an existing steam power plant is converted by means of a gas turbine unit with reheating, the latter comprising two gas turbines in one housing and an electrical generator. In a special embodiment, the new circuit can also be used for coal-fired steam generators. The new circuit is also advantageous for new, large combined plants (output of 700 MWe for example) in which a considerable proportion of fuel is burnt in the steam generator. <IMAGE>

Patent DE-3318901-A1 (DE)
Title: Process for reliable fastening of a support attached to an exterior surface of a flat moulding in the region of the surface edges and mould for this
Inventor: STANGE GUSTAV
IPC: B29C63/04
Filed: 1983-05-25
Abstract: In the manufacture of planar structures provided with supports, such as for example interior linings of vehicle doors, reliable fastening of the support in the region of the surface edges is a problem. Hitherto a complete surrounding of the edges with the support was carried out either in several operations and/or manually. This is expensive. A simple folding over against the front side of the edges, which is also carried out, is not sufficiently durable. It is therefore proposed according to the invention to place the support against a front side of the surface edge in the mould in a first bending operation and then in a further bending operation to lay it on the other exterior surface following the front side of the flat edge, with this folding over being carried out by means of two correspondingly traversible and independent shaping elements within the mould.
