Patent DE-3742317-A1 (DE)
Inventor: REPENNING DETLEV DR
IPC: C23C14/02
Filed: 1987-12-14
Abstract: A process for producing corrosion-resistant, wear-resistant and compression-resistant layers on a metallic substrate (workpiece) is proposed. According to the process, the substrate is first subjected to diffusion hardening in a first process step. Then, using a PVD process, an intermediate layer is applied to the layer formed by diffusion hardening. Finally, in a third process step using a PVD process, a very hard final layer is applied to the intermediate layer. All three layers in their totality form, on the metallic substrate, a layer which has the intended corrosion-resistance, wear-resistance and compression-resistance.

Title: Method and the corresponding devices for guiding a laser beam by means of a flexible mirror surface
Inventor: REENTS HEINRICH PROF DR ING
IPC: B23K26/082
Filed: 1988-02-18
Abstract: The laser beam is suitable for the energy-saving representation of data, items of information and images. The systems, which are commercially available, for deflecting laser beams are based on the deflection by means of 2 mirrors. The method presented in this invention needs only one mirror system for the deflection. This system is influenced by electrical/magnetic fields in such a manner that any pictures can be represented in each desired linear magnification (image scale, reproduction scale). Changing the pictures and the linear magnification is reduced to software changes. The mirror system receives the deflection information via a control/regulation unit which, if necessary, can be provided with its own intelligence. The deflection system presented is cost-advantageous in the production. In this way, multitudinous novel ranges of application open up for the laser in advertising, production, medical technology and to the protection of buildings, sites and objects, to name but a few.
Patent DE-3805686-A1 (DE)
Title: Amplifier circuit, particularly for sensors
Inventor: RIEWE FRANZ-JUERGEN
IPC: H03F1/02
Filed: 1988-02-24
Abstract: In an operational amplifier (OP) connected to a sensor (IR) with inertia via a coupling capacitor (C1), the input (E+) connected to the coupling capacitor is connected at the same time to a voltage divider (R2, R3), the resistors of which, together with the feedback resistor (R1) of the amplifier and the resistor (R4) connecting this feedback resistor and the associated second input (E-) of the operational amplifier to earth, are dimensioned in such a manner that the resting potential (UA) at the output of the operational amplifier corresponds to approximately half the supply DC. This dispenses with the settling time of the RC section and thus considerably shortens the settling time of the circuit arrangement.

Title: Apparatus for the remote-controlled opening of pipe connections
Inventor: RAUSCH WOLFGANG
IPC: F16L55/26
Filed: 1988-03-02
Abstract: If a tube is drawn into pipelines in order to seal them, all of the lateral pipe connections are also closed. The pipe connections must be opened again, but this is not readily possible in the case of pipelines which are narrow and therefore not accessible on foot. In the case of pipelines laid underground, the only solution hitherto has been to dig up the ground at the locations of the pipe connections. The novel apparatus is remote-controlled and comprises a camera and illuminating device mounted axially rotatably with respect to the housing of the apparatus and also a tool holder mounted pivotably on the illuminating device and having a tool for opening the pipe connections. The apparatus enables a remote-controlled opening of the pipe connections, so that digging up of the ground, which entails high costs, is no longer necessary. <IMAGE>

Title: Thermoformable integral composite material and process for its production
Inventor: ROZEK HARRY J
IPC: B32B5/24
Filed: 1988-04-08
Abstract: A one-part composite material is produced without the use of adhesives. In this case, fibres of a layer of unwoven fibres are needle-punched into a thermoformable foam element, to be precise preferably into a thermoformable semi-stiff or semi-rigid foam element having foam cells which are expandable under heat. A binder resin is applied to the layer of unwoven fibres and dried in an oven. When this preferred composite material is subsequently formed into a moulding by a thermoforming process, the foam cells expand with the fibres securely enclosed in the foam element.

Title: Self-aligning screw bearing
Inventor: MOLL BERNHARD
IPC: F16C31/02
Filed: 1988-05-05
Abstract: The invention relates to the installation of a self-aligning flanged nut in pedestal bearings, flanged bearings, spherical plain bearings and sliding bearings and combined self-aligning shaft bearings, pedestal bearings and flanged bearings in machines and plant. The prior art is as follows: self-adjusting ball bearings and sliding bearings and clamping devices for shafts without angular adjustment are known. The invention of the self-adjusting flanged nut and self-aligning shaft bearing has the advantage that in welded constructions, which by their very nature are subject to distortion, no finish machining by means of a portable grinder or a milling machine is required. The spherical inner ring 4 with the round bar 8 adjusts automatically to the correct angular position when the shaft with screw 1 is rotated. In the case of accurate adjustment of the screw or shaft 1, in machine tools for example, adjustment is carried out by centring the pedestal or flanged bearing housing 0 and guaging by means of the fixing screw 12. By virtue of the milled recess in the inner ring 4 and insertion of the round bar 8 in the said recess, a wobbling motion of the shaft or screw 1 is not possible. <IMAGE>

Title: Method for dressing a grinding wheel
Inventor: WEDENIWSKI HORST JOSEF DR
IPC: B24B49/18
Filed: 1988-12-21
Abstract: A method is used to dress a grinding wheel (12). A dressing roll (40) is moved by means of a numerically controlled multi-coordinate movement unit (46, 47) along a rough surface (30, 31) of the grinding wheel (12). In this way, a preset circumferential profile of the grinding wheel (12) is produced. In order to simplify the process control of the grinding operation and in particular to enable, in a simple way, time optimisation during high-speed rough grinding with a high time-cutting volume, first of all a circumferential profile is determined as a function of process parameters of a grinding operation to be carried out on a workpiece (20) by means of the grinding wheel (12) after dressing, and this circumferential profile then produced on the grinding wheel (12) by means of the dressing roll (40) (Fig. 1). <IMAGE>

Title: High-performance filtration method
Inventor: CZEKALLA CHRISTOPH DIPL BIOL
IPC: C02F1/64
Filed: 1989-02-08
Abstract: The invention relates to a method for the contact removal of iron and manganese from ground waters and surface waters (raw waters) in closed rapid filter installations, in particular for the treatment of raw water having medium and high iron and manganese contents, the raw water previously enriched with oxygen flowing at a certain filter rate through a filter medium which becomes blocked as a result of the precipitation of the heavy metals and therefore, after a certain flow time (filter period) is broken up by air flush and is cleaned of sludge by a subsequent water wash (filter backwashing), which is followed by the next filter period with subsequent filter backwashing. To improve performance, it is proposed to increase the filter rate during a filter period.

Abstract: A measuring arrangement for measuring the variation of a fluid quantity in a storage space (2) which receives the liquid has a measuring chamber (8) and a reference measuring chamber (10) of identical construction. Both chambers (8, 10) are connected to the storage space (2) so as to communicate before the measurement so that identical liquid levels (14, 15, 16) are established. For the measurement, the connection between the reference measuring chamber (10) and the storage space (2) is interrupted. Therefore, when liquid is consumed, the liquid level (14) in the measuring chamber declines in the same manner as the liquid level (16) in the storage space (2) while the liquid level (15) in the reference measuring chamber essentially remains the same. The levels (14, 15) are measured by means of interval measuring devices (24, 25) and subtracted from one another in an evaluation device (36) and processed, if appropriate, to form a liquid consumption value after correction due to temperature-related changes in the liquid levels (14, 15). <IMAGE>
