Inventor: WOERNER HANS
IPC: E04D3/08
Filed: 1980-12-19
Abstract: The panel-securing means has a profile bar (1) with webs which delimit a channel (3). The channel (3) is provided, on its open longitudinal side, with a narrowed portion (3b) which is adjoined, in the direction of the channel base (3a), by a widened portion (3c). An anchor (5), formed from a single-piece plastic body (7) and a threaded bushing (9) inserted therein, has a foot (7a) which, on mounting, is introduced, through the narrowed portion (3b), into the channel (3) and is then turned, until the stop surfaces (7m) of the foot (7a) come to a stop, into a retaining position, in which the foot (7a) engages behind the narrowed portion (3b). A resilient clamping part (7d), located outside the channel (3) and belonging to the plastic body (7), is provided with flanges which rest, in the retaining position, in the prestressed state on the profile bar (1) and have a latching nose (7g) latching into the channel (3). The anchor (5) can thus be introduced without difficulty into the channel (3) at any point and be moved into a retaining position, in which it is held such that it cannot turn and also, to some extent, such that it cannot be displaced. <IMAGE>

Title: Process and apparatus for producing sponge iron
Inventor: SANTEN SVEN
IPC: C21B13/12
Filed: 1981-02-07
Abstract: In a process for producing sponge iron by continuous reduction of iron oxides in a blast-furnace (shaft furnace), the reaction gas is removed from a blast-furnace, and essentially the entire CO2 and H2O is removed from this reaction gas. The reaction gas is then divided into at least two part-streams and one of these part-streams is fed to a gas generator which is mainly packed with a solid reductant and has a plasma burner and devices for injecting an oxidant. This reaction gas is heated by the plasma burner. The heated gas is injected with the oxidant in order to form an intermediary gas mixture, which mainly consists of CO and H2. In the process, said intermediary gas mixture is held at such a temperature that the ash contained in the solid reductant forms a slag. Furthermore, this intermediary gas is mixed with at least one of the other part-streams in such a ratio that the temperature of the resulting reduction gas is suitable for reducing iron oxides in a blast-furnace. Said reduction gas is injected into the bottom part of a blast-furnace and is passed upwards through the blast-furnace, which makes it possible to reduce iron oxides in the blast-furnace. The reduced iron is drawn from the furnace. The invention also comprises an appliance for carrying out this process.

Title: Device on looping machines for the continuous transfer of a tape attached to the needles of the needle ring
Inventor: HEINL THOMAS
IPC: D05B7/00
Filed: 1981-05-09
Abstract: A looping machine, intended for connecting bordering edges, such as, for example, tapes, to a body fabric, is equipped with a device, by means of which the tape is laid onto the needles of the needle ring beyond the body fabric attached to the needle ring and by means of which the displacement of the ribs of the tape relative to one another, occurring during this transfer operation, is eliminated. The tape is first laid on the needle ring by means of a cylinder via a sliding plate and is subsequently advanced in the direction of the rotational movement of the needle ring by a roller pressing the transferred front part of the tape against the sliding plate. The extent of displacement of the front part can be adjusted continuously by a variable rotational speed of the roller, in such a way that mutually corresponding ribs of the front part and of the back part simultaneously enter the following sewing device of the looping machine.

Title: Pneumatic conveying apparatus for bulk material, especially agricultural bulk material, such as hay, straw and maize
Inventor: SCHMIDHEINY WERNER
IPC: A01D87/10
Filed: 1981-05-12
Abstract: The conveying apparatus has a suction intake hopper (2) which makes a transition into a vertical conveying pipe (6). The latter contains a widened portion (28) which tapers in the conveying direction at a conicity of K = 0.07 to 0.15. The cross-sectional surfaces (F3, F4) on both sides of the widened portion (28) are of approximately equal size. An annular nozzle (12) opens into this widened portion (28) in a conveying direction and is connected to a blown air duct (14) which is fed by a fan (16). The blown air duct (14) forms a calming chamber (30) upstream of its transition into the annular nozzle (12).

Title: Process for making bellows from metal alloys
Inventor: BODJAKO MICHAIL N
IPC: C21D8/10
Filed: 1981-07-10
Abstract: The invention relates to the technology of making thin-walled flexible sensors. The process comprises rolling out a tubular blank for the purpose of reducing its wall thickness with spatial deformation, heating of the rolled-out tubular blank to a temperature higher than the recrystallisation temperature of the alloy, and subsequent cooling. This is followed by local transverse deformation of the walls of the tubular blank to form annular grooves and to shape the folds by plastic deformation of the tubular blank while it is being compressed in the axial direction, and generating a positive pressure in its interior. The blank which then contains the folds is heated to a temperature of the maximum precipitation rate of finely disperse alloy phases and left at this temperature. The rolled-out tubular blank is heated, according to the invention, by means of electric current at a heating rate of 100 to 800 DEG C/second. The blank containing folds is heated by means of electric current at a heating rate of 25 to 100 DEG C/second to the temperature of the maximum precipitation rate of finely disperse alloy phases and left at this temperature for 0.5 to 120 minutes. The invention can be applied particularly successfully in the construction of equipment.

Abstract: With the invention, an action installation for advertising or play purposes is described, with a single-axle vehicle which is movable in a gyroscope-like manner and which with its axle adheres magnetically to and runs on two guide rails which run parallel at least on a part of their length. According to the invention, the vehicle is driven by a drive device being provided for the guide rails, via which the guide rails are driven, so that the single-axle vehicle runs with its axle on the guide rails. The vehicle can then take up energy from the movement of the guide rails without itself requiring a drive for its axle. In a preferred embodiment, the guide rails are combined into a helical rail and are caused to carry out a pivoting movement by the drive device. In this connection, the vehicle carries out a constant upward and downward movement on the helical rail.

IPC: B42B4/00
Filed: 1982-06-29
Abstract: The invention relates to a wire coil changing device which is suitable, in particular, for stitching apparatuses in nonstop operation in rotary printing machines. In this case, the aim of the invention consists in a wire coil changing device with which the stoppage time of the rotary printing machine and the risk of accidents are reduced by simple, uncomplicated, inexpensive means. In accordance with the object, this is to be achieved by a wire coil changing device in which the wire is conveyed away from two exchangeable wire coils. The effort for removing the remaining wire and for drawing in the new strip of wire is to be reduced and the ease of operation of the rotary printing machine is to be increased. This is achieved by a device in which each wire coil can be inserted in a cartridge which has two receivers (4 and 5) with which it can be pushed into or exchanged in guides (9 and 10 or 11 and 12) of a cartridge holder. <IMAGE>

Title: Control device for a drive system with a high load
Inventor: HERTEL EASTCOTT PETER DE
IPC: H02P15/00
Filed: 1982-12-09
Abstract: A description is given of a control device for stopping a large milling plant which is driven by two synchronous motors which are coupled to the milling plant via compressed-air couplings. A coupling operating device is provided which during a prescribed period exerts on the couplings a prescribed pressure which is so large that the couplings are at least partially engaged, but which is not so large that the couplings are completely engaged. The control device further contains an activation device which periodically activates the operating device in order to bring about the previously determined exertion of pressure. The activation device activates the operating device during a previously determined period which suffices to stop the movement of the milling plant and of the synchronous motors. It is possible using such a control device for the milling plant to be stopped relatively quickly, and a cost saving design is possible.
