Patent DE-3623098-A1 (DE)
Title: Method for debarking treetrunks (boles) and apparatus for carrying out the method
Inventor: LOEBNER ANDREAS DIPL ING
IPC: B27L1/05
Filed: 1986-07-09
Abstract: A method for debarking treetrunks by means of an annular debarking apparatus is proposed, in which, in a known manner, the pressing force of the peeling tools against the trunk can be arbitrarily changed in operation and, with running rotor, the peeling tools can also be shifted into an open position out of contact with the trunk. The method is characterised in that the controlling of the pressing force and the opening of the tools are effected solely via the arbitrarily changeable rotational speed of the rotor, using the movement-effective mass of the peeling tools, which counteracts an elastic force stressing the peeling tools, in a known manner, permanently into the closed position. The elastic force here remains unchanged from outside during the operation of the annular debarking apparatus. The particular advantage of the method according to the invention consists in that it can be carried out with a high degree of operational reliability and considerably less constructional expense on the part of the annular debarking apparatus compared with the known methods which allow arbitrary control of the pressing force of the peeling tools and shifting thereof into an open position with running rotor. Furthermore, an annular debarking apparatus for carrying out the method according to the invention is proposed, which is characterised in that the rotor drive 5,6,7 for driving the rotor 4 is designed with arbitrarily changeable rotational speed.

Title: Gas bubble brick for metallurgical vessels
Inventor: BENDER GUENTER
IPC: B22D1/00
Filed: 1986-09-17
Abstract: Gas bubble bricks (1) for metallurgical vessels consist of a gas-permeable shaped brick (2) made of refractory material, which can be inserted into the wall or bottom of the vessel, a gas tight sheet-metal cladding (3) partially surrounding the shaped brick and welded together from a sheet-metal case (5) extending around the peripheral surface (6) of the shaped brick (2) and a sheet-metal base (8) arranged on the gas-inlet-side face (7) of the shaped brick, and also a gas supply pipe (4). To ensure that no moisture gets into the melt to be treated from the gas bubble brick during the bubbling operation, the gas-outlet-side face (10) is fitted, for transporting and storage of the gas bubble brick (1), with a gas- and moisture-tight cover (11) made of thermoplastic, and the gas supply pipe is sealed with a plastic cap (13). <IMAGE>

Title: Method and installation for the production of tube blanks
Inventor: MOELTNER HERMANN DIPL ING
IPC: B21C5/00
Filed: 1986-09-25
Abstract: The invention relates to a method for the production of tube blanks for the production of seamless tubes, in which, first of all, an ingot at rolling temperature is pierced by a skew rolling stand and is then provided at its leading end, by dishing, with a stop for a push-bench mandrel bar, after which the hollow ingot with the mandrel bar in it is pushed to form the tube blank and, finally, the tube blank is removed from the mandrel bar. According to the invention, a centering piece is to be inserted into the longitudinal hole in the leading end of the hollow ingot after piercing and is to be dished. The centering piece serves as an inner die during dishing, thereby sparing the shank bar and mandrel bar and giving a precisely defined hollow-ingot base.

Inventor: SANDER WOLFGANG
IPC: B23F15/06
Filed: 1987-01-09
Abstract: A process is used to machine workpiece blanks (14) by stock-removal in order to manufacture spiral compressor blades. The blades have at least a spiral wall (13) that extends perpendicularly to a plate (12) having an essentially planar surface (15). In order to minimize the machining time of the workpiece blanks (14) and to optimize the quality of their surface, the workpiece blank (14) is clamped in a CNC-grinding machine (20 to 24, 30 to 34) in such a manner that the surface (15) of the plate (12) stands vertically. The workpiece blank (14) is machined by a tool (30) rotating around a horizontal axis (35) at more than about 30,000 revolutions/minute. A controller (34) modifies the position of the workpiece blank (14) relative to the tool (30) along polar and cartesian coordinates.

Title: Front-tyre packers for tractors for consolidating the arable soil between the tractor wheels
Inventor: BOEDECKER KNUTH
IPC: A01B29/04
Filed: 1987-10-13
Abstract: The present invention relates to front-tyre packers for tractors for consolidating the arable soil between the tractor wheels. In the state of the art, there have repeatedly been problems with the poor steerability and high rolling resistance of such packers.

Title: Folding box with tearing strip
Inventor: BERGER WERNER
IPC: B65D5/54
Filed: 1988-02-27
Abstract: A folding box has a peripheral tearing strip (12) with spacing from the bottom of the box. Cuts (14, 15) in the two side walls (2, 3) separate the tearing strip (12) and run upwards into lateral closure flaps (8, 9) where they end before the free edges of said closure flaps. As a result, a bridge (19) which connects the two slot edges remains in each case. When the folding box has been filled, this bridge (19) is separated. When the two-part tearing strip (12) has been torn open, part of the folding box can be removed which thus forms a display container which is open at the front. <IMAGE>

Title: Electrical temperature-control systems with or without feedback for containers made of glass, plastic or metal with shaped, flexible heater
Inventor: LITTERST WERNER-ALFONS
IPC: A61M5/44
Filed: 1988-06-24
Abstract: Temperature-control systems for containers of various shapes are characterized in that they are employed for controlling the temperature of liquids, solutions and medicaments in the medical field. The temperature-control systems can also be employed in the industrial field. For reducing the risk for the patient and for saving medicaments of a diagnostic or therapeutic type, as well as for reducing the energy requirement of conventional temperature-control systems, e.g. water baths, heating cabinets and hot plates, the present invention offers significant advantages. In the industrial field the present invention permits processing of liquid materials, solutions, fuels and other liquid media which has hitherto not been possible at all or has been possible only depending on the ambient temperature. Temperature-control very frequently requires high technical and energy outlay. The highly insulated construction of the temperature-control systems also ensures reliable use in any environment. Another advantage of the present invention is the high degree of adaptability to any body or container to be heated. There are no technical limitations to special constructional types because the present invention can also be produced by a wide variety of casting, embossing and preshaping methods.
