Title: Process and equipment for separating off slag
Inventor: WRONKA BODO
IPC: C21B7/14
Filed: 1982-08-20
Granted: 1983-11-17
Abstract: The invention relates to a process for separating off the slag floating on molten metal in a hot-operated metallurgical vessel, especially in electric metal-melting furnaces, at an overflow edge, a positive pressure being exerted on a part of the slag/melt level in such a way that the remaining part of the melt with the slag located thereon is lifted with the melt level up to the overflow edge. The slag layer thus flows off over the overflow edge. The equipment for carrying out the process consists of a vessel (1), in which a partition (2) is fitted which separates a small part of the slag/melt. In this partition, a transfer opening (3) is provided which joins the separated region (5) of the vessel (1) to the remaining vessel space (8). In a section of the vessel wall, located outside the vessel region (5) separated off, an overflow edge (7) is located. <IMAGE>

Title: Clamping wedge for a forging hammer
Inventor: LANGENSTEIN ROLF
IPC: B21J13/03
Filed: 1985-10-26
Granted: 1987-03-12
Abstract: There is a clamping wedge 5 where an intermediate layer 9 of variable thickness is provided between a main-body plate 6 and a pressure plate 8 and the pressure plate 8 is guided on the main-body plate 6 in such a way that it can be moved transversely to the plane of the plate. It would be desirable here to simplify the production and maintenance of the clamping wedge. This is achieved if the clamping wedge is designed for driving in with the taper in a longitudinal direction and if the intermediate layer 9 is formed by a rubber-like, void-free material which can be compressed elastically through free spaces 14 for the reception of displaced material. Thus, on the one hand, the clamping wedge is designed like a conventional solid clamping wedge with a taper and for driving in my means of rams and, on the other hand, has the advantages associated with the intermediate layer of variable thickness. <IMAGE>

Title: Plastic fibres for adding to e.g. concrete - for easy handling are used packed in porous bags of water-soluble e.g. polyvinyl alcohol which dissolve during mixing with concrete etc.
IPC: E04C5/07
Filed: 1992-04-28
Granted: 1993-06-17
Abstract: Plastic fibres. for use as additives to concrete or mortar in building materials, are held in water-soluble bags which dissolve during the mixing with the concrete or mortar. The bags are pref. polyvinylalcohol; the fibres concerned are preferably polypropylene, polyethylene, acrylipnitrile of insoluble polyvinylalcohol. The fibres used are produced by shredding plastic films; to minimise the volume of the bags when filled with the fibres the bags are made porous, e.g. by perforating. Alternatively the bags can be intermittently welded o sewn. They can be made in different sizes so that different quantities of fibres can be utilised. Bags containing the fibres are mixed with the appropriate quantity of e.g. concrete for example in a 30 tonnes travelling mixer taking 6 cu.m mix. This mixing requires some 6 mins. The necessary polyvinylalcohol bags take only max. 1 min. to be added and dispersed. ADVANTAGE - The fibres used are easily handled during mixing. They can be accurately measured out.

Title: Device for homogenising the light distribution of a laser beam
Inventor: BUECHER HERMANN DR
IPC: B23K26/064
Filed: 1993-12-07
Granted: 1995-04-27
Abstract: Many laser-beam sources have an energy-density distribution in the beam cross-section which deviates from the desired, constant energy density and whose local peaks can lead to an impairment. In order to provide a device for homogenising the light distribution of a laser beam, in which all of the leaving partial beams have the same beam divergence as the primary beam, there is provided in the beam path of the laser beam an optical system which has a beam splitter and three deflecting mirrors. The partial beam reflected by the beam splitter and deflected by the deflecting mirrors and the partial beam transmitted by the beam splitter are combined to form an overall beam whose partial beams have an offset. The two partial beams which have an offset result in a very high degree of homogeneity of the laser-beam bundle, the overall beam having the same beam divergence as a primary laser beam. The deflecting mirrors have a low numeric aperture and are cost-effective. The device is preferably used in treating (processing, machining) materials by means of laser radiation.

Title: Arrangement for the cumulative power regulation of at least two hydrostatic variable-displacement pumps
Inventor: ERKKILAE MIKKO
IPC: F04B49/06
Filed: 1994-02-18
Granted: 1995-04-06
Abstract: A device is disclosed for regulating the total output of several variable displacement pumps (1, 2) provided each with a regulating valve (18) for regulating the displaced volume. A control pressure that corresponds to the working pressure of the variable displacement pumps is applied to the regulating valves (18) against a counterpressure. The regulating valve (18) responds when the control pressure exceeds the counterpressure, regulating the variable displacement pump according to  a characteristic curve (KL) of constant torque. In order to adjust the individual driving torques in a simple manner and to prevent the torques from exceeding the set values, an electronic control unit (16) is connected to the measurement sensor (25) that senses the volumes displaced by the variable displacement pumps. The electronic control unit (16) stores the sum of the set values of the counterpressures and the torque characteristic curves (KL) of the variable displacement pumps and has a set value regulator (27) that distributes the set value sum. The electronic control unit (16) further sets said torque characteristic curves (KL1, KL2), transmits control signals to the associated control element (24) that generates counterpressures corresponding to predetermined counterpressure set values, senses the working pressure (p) corresponding to the displaced volume (V) on the torque characteristic curve (KL1, KL2) when the regulating valves respond, converts said working pressure (p) into a control signal and transmits said signal to the control element that generates a counterpressure.
