Patent DE-3407958-C1 (DE)
Title: Method and apparatus for monitoring a water curtain
Inventor: STAUBERMANN HORST DIPL-ING
IPC: B21B45/02
Filed: 1984-03-03
Granted: 1985-11-28
Abstract: The invention relates to a method for monitoring a water curtain used for cooling moving sheets or strips and emerging continuously in free fall with laminar flow from the slot of a water box extending transversely across the sheet or strip. Since a disturbed water curtain means non-uniform cooling of the sheet or strip, thereby having a negative influence on the quality of the cooled material, a disturbance in the water curtain must be detected in order to ensure uniform material quality. It is therefore the object of the invention to provide a method and an apparatus for carrying out the method, by means of which the monitoring of the water curtain is made possible. As a solution, it is proposed to detect a disturbance in the curtain by the interruption of an ultrasonic signal or by an alteration in the electrical resistance in the curtain or by an alteration in the pressure in the water box and use this to the signal disturbance.

Title: Talk-back device for a subscriber station of a key-controlled intercom system with line selection
Inventor: NEUMANN DIRK DIPL-ING
IPC: H04M9/00
Filed: 1984-05-18
Granted: 1985-08-29
Abstract: A talk-back device for a subscriber station of a key-controlled intercom system with line selection. In the intercom system, a ringing signal comprising pulses is fed in each case via the line circuits (L1 to Ln) to the called subscriber station (TSO) and a continuous signal is fed as a busy signal to the other subscriber stations. Between the subscriber station (TSO) and the central station (ZT), a circuit is disposed in which each line circuit (L1 to Ln) is coupled in each case with one counting device (Z1 to Zn) which, when a ringing signal arrives, after a pre-defined number of ringing pulses emits a control signal which is fed to a bistable multivibrator (FF1 to FFn) whose output is connected via an AND element (U11 to U1n) to an electrically activatable switching device (Tr11, Tr21 to Tr1n, Tr2n) by means of which the line circuit concerned can be connected to a voltage source. The second input of all the AND elements (U11 to U1n) can be connected to the voltage source via a central ringing key (RT) which is common to all lines and is connected to the subscriber station. A reset device (FF0) is provided by means of which, following actuation of the central ringing key (RT) and/or at the end of a defined time span, a reset signal is fed to all the counting devices (Z1 to Zn) and to all the bistable multivibrator (FF1 to FFn). <IMAGE>

Title: Producing fine grain ceramic powder - by foam expansion of starting material to produce bubbles with thickness in nanometre region
Inventor: WUESTEFELD ALOYS DR
IPC: C04B35/626
Filed: 1993-04-30
Granted: 1994-05-19
Abstract: Ceramic powder with particle diameters of a few nanometer are produced by heating the starting material to expand it and drive off the water of crystallisation. The bubbles produced by the foaming process have thin walls of a few nanometers thickness. During foaming the starting material is broken down into fine particles. The raw material may be basic aluminium sulphate of composition Al2(SO4)3.Al2O3.6H2O which is heated to expand the particles and drive off the water. It is then heated at a higher temp. to drive off the acid. The raw material may be obtained by heating an Alaun solution at 180-200 deg.C during which the water is replaced by SO3 according to the equation: K2SO4.3AL2O3.9H2O + 4.5SO3 = K2SO4.3Al2O3.4.5SO3 + 9H2O. After washing out the K2SO4 and filtering, the basic aluminium sulphate is reheated to expand the particles and drive off the water of crystallisation. Foaming agents are pref. added to the Alaun solution to ensure that the particles of aluminium sulphate stick to the bubble surfaces. USE/ADVANTAGE - Producing fine ceramic powder of aluminium oxide, silicon nitride, silicon carbide and zirconium dioxide. Process is simple and does not require high technical costs.

Title: Method of machining a workpiece on a CNC automatic, and a CNC automatic
Inventor: GROSMANN WALTER
IPC: B23B3/16
Filed: 1993-09-11
Granted: 1995-01-19
Abstract: CNC automatic with at least one slide system for working with turning tools and rotating cutting tools. The slide system has an X-, Y- and Z-axis and carries a tool turret designed as a so-called disc turret. To achieve as small a distance as possible between the cutting plane defined for a turning operation and the slide system, the Y-axis forms a relatively small acute angle with the perpendicular to the cutting plane, so that, by controlled rotation of the tool turret about the turret axis, a rotationally drivable cutting tool carried by it and located in the working position can be pivoted with its axis of rotation out of the cutting plane by an acute angle in the direction of the slide system in such a way that its effective cutting area performs a movement which has a component running in the minus direction of the Y-axis. <IMAGE>
