Inventor: KOLB WERNER DIPL-ING
IPC: F04D29/54
Filed: 1985-11-08
Granted: 1987-02-19
Abstract: An axial blower with an intake that tapers conically into a cylindrical component. An impeller rotates inside the cylindrical component. A stationary channeling ring of approximately the same diameter as the cylindrical component is positioned upstream of the impeller and surrounded by an annular channel. The channeling ring is approximately equidistant from each end of the annular channel. Diversion blades are positioned inside the annular channel and adjusted in relation to its axis. To make the blower easier and less expensive to manufacture and to increase its breakaway limit, the diversion blades consist of flat sheets of metal and both their upstream and their downstream edges slope.

Patent DE-4103701-C1 (DE)
IPC: F16L17/04
Filed: 1991-02-07
Granted: 1992-06-17
Abstract: Devices for the sealed connection of two pipes are known, which have a sealing sleeve with which contact can be made by a clamping strip, it being possible to tighten the clamping strip by means of a clamping screw. In order further to improve the lateral stiffness and the sealing function of such connecting devices, a narrow, circumferential bead (26), which engages in a fitting manner into in each case one edge section (32) of the sealing sleeve (11) with a trough-shaped cross-section, is provided close to each outer edge of the clamping strip (12). When the clamping strip (12) is tightened, the edge sections (32) are pressed by the beads (26) against the external circumference of the pipes (10) which are to be connected. On its external edges, the clamping strip (12) has flanges (28) which project radially inwards in such a manner that, although they overlap the external sides of the edge sections (32) of the sealing sleeve (11), and hence prevent the material of the sealing sleeve (11) being forced outwards, said flanges (28) have radial play with respect to the external circumference of the pipes (10) which are to be connected, in order to prevent the metallic clamping strip (12) being able to form a sound bridge, as is the case in the prior art. <IMAGE>

Patent DE-4213504-C1 (DE)
Inventor: HILPERT THOMAS DIPL-ING
IPC: G06F11/00
Filed: 1992-04-24
Granted: 1993-06-24
Abstract: The invention relates to a method for reducing interference signals which are caused by the power consumption, dependent on the executed command code, of processors, in particular digital signal processors, which perform cyclically repeated program routines which are initiated by interruption signals and which, during their running time, result in a first mean power consumption, the running time of the program routines being shorter than the time between two consecutive interruption signals. The cyclic modifications of the power consumption caused by this operating mode of the digital signal processor are prevented by performing a delay routine between consecutive program routines which results in a mean processor power consumption corresponding to the program routines. <IMAGE>

Granted: 1994-06-01
Abstract: The invention relates to a profile die (3) for extruders (1) with individually activatable temperature-control elements (4a, 4b) influencing the flow behaviour of the material. The temperature-control elements (4a, 4b) are arranged in the flow channel (3a') of the material, downstream of the screw (2) of the extruder (1) and upstream of the profile-defining region (3c) of the die (3), in such a manner that the temperature of the extruded material can be increased in selected zones of the cross-section. By this means, it is possible, even in the case of complicated cross-sections and in the case of different profile-defining parts not equipped with temperature-control elements (4a, 4b), to influence the wall thickness of the profile. <IMAGE>

IPC: E04B1/98
Filed: 1996-11-08
Granted: 1998-05-11
Abstract: The damper consists of a mass which is supported by e.g. three rollers on a dished plate with cross section of certain curvature. The curved dished support acts as a spring. The rollers cause changing stresses in the plate, during rolling, so that stress energy is continuously lost causing a damped movement of the mass The curvature of the support plate determines the frequency of the movement of the mass. The thickness of the plate determines the degree of damping. The mass can be cylindrical and placed inside the chimney or ring shaped in which case it is placed around the chimney

Title: Multi-functional tensioning system for anchoring mostly dismantlable constructions in ground
Inventor: DRENTH JOHANNES METO
IPC: E04H15/62
Filed: 1997-03-24
Granted: 1997-04-22
Abstract: When necessary, anchor plates can be fitted under the head of the screw anchor with the anchoring line positioned further from the centre of the screw anchor. In this event, the screw anchors cannot absorb the horizontal forces. When greater forces need to be transmitted to the ground, anchor plates can be applied with several screw anchors. The anchoring lines are fitted under the effect of a tension device. The construction is connected to the anchoring line, i.e. an elastic tension line which is always anchored to the screw anchors. By tensioning the tension line the tension force can be more or less regulated. Connecting components between the anchoring line and the tension line and between the tension and the construction provide a connection whereby the tension line can move freely.
