Patent DE-4241411-A1 (DE)
Inventor: WEINBERG WALDEMAR DR
IPC: C03C17/04
Filed: 1992-12-09
Abstract: 2.1 Hitherto, differences between the coefficients of thermal expansion of glass-ceramic substrates and decorative layers made from, in particular, lead-free base enamel meant that only very thin, relatively rough colour layers with restricted service properties could be baked on the substrate. The object is to provide a process for the production of substrates coated, in particular, with lead-free ceramic colours are made from preshaped borosilicate glass or glass-ceramic elements, allowing an intensely coloured, firmly adherent decorative layer having the thickness necessary for continuous coating to be obtained. 2.2 Before the baking together with the pigments, heat-resistant, optically inactive, elastic, inorganic substances in finely divided form which are chemically inert towards the base enamel and the pigments are admixed with the base enamel in an amount of 1-20% by weight. The load limit of the resultant decorative layer is thus not achieved until a larger layer thickness. 2.3 In this way, decorative layers of, in particular, lead-free base enamel can be applied in a firmly adherent manner to substrates having a low coefficient of thermal expansion.

Title: Non-destructive method for determining elastic constants of boards
Inventor: BROEKER FRIEDRICH-WILHELM DR
IPC: G01N33/46
Filed: 1993-06-26
Abstract: In the production of boards, the board properties must be measured and evaluated continuously for quality and production control. The current destructive test methods on small test-bodies allow determination of the board properties only with a considerable time delay, so that faulty production and fluctuations quality can only be detected at a late stage. Non-destructive test methods allow the detection of the board properties actually on the production line directly after board manufacture. According to this novel method, narrow board strips which, for example, have been taken from a board, or entire boards are tested in a continuous method. The elastic constants are determined by measuring the board deflection and the forces required for this. The elastic constants are calculated from the measured quantities. This method is suitable for continuous monitoring of production lines, for example in the derived timber product and gypnum plaster board industry. This method is capable of giving indications of the board properties without time delay. <IMAGE>
Patent DE-4321515-A1 (DE)
Title: Locating method and leak-finding device for leaks in odorising systems
IPC: G01M3/20
Filed: 1993-06-29
Abstract: The method described below is used for locating leaks in odorising stations and in other systems where operations are carried out with odorising agents. At the heart of the method there is a portable device which essentially consists of     - a compressed-air pump,   - a pneumatic hose,   - a compressed-air pistol and   - a sensor for registering odorising materials. The principle of the measuring method is the dynamic comparison of the concentration variations of the odorising material at various measuring locations. For this purpose, the compressed-air pump is set up outside the region which is contaminated with odorising agent, for example outside the odorising station, in the region of fresh air. Using the compressed-air pistol, the air which is contaminated with odorising agent is blown away in the vicinity of the suspected object. After completing the blowing process, the gas measuring cell is activated. This sensor measures the increase of odorising agent concentration at the erstwhile blowing location. The response time, the slope and the maximum concentration of odorising agent are registered and stored. After reaching a stationary condition, the measurement is repeated at another measuring location. Finally, the individual kinetic variations are compared with one another and the measuring point having the most intensive concentration increase is determined. If required, the sequence of measurements in the vicinity of the measuring point found out during the first pass is repeated using a finer geometrical grid.

Filed: 1993-09-16
Abstract: In the case of a plate pack for lead-acid batteries, the grid plates of which have thicker plate lugs in the case of one polarity than those of the other polarity, the volumes and areas of the two types of lug are evened up by tapering the thicker lugs in a wedge-shape towards the end (figure), the end thickness a2 of the said thicker lugs being less than the thickness of the thinner lugs which are left in their original state with a completely rectangular cross-section. Under this precondition, the heat balance of each of the two types of lug is the same during the fusing on of the bridging lead in identical casting moulds and at the same lead temperature. The thicker lugs obtain their wedge-shaped geometry by machining with an end milling cutter. <IMAGE>

Title: Actuating device with a securing means
Inventor: KITTEL FRIEDRICH DIPL ING
IPC: H02K7/116
Filed: 1993-10-26
Abstract: An actuating device, in particular for a motor-vehicle friction clutch, having a drive which, at its drive shaft, produces a rotary movement for a driven shaft, and having a crank gear which converts the rotary movement of the driven shaft into an essentially translatory movement of an output member, is intended to be designed such that damage can be prevented even in the event of operating-voltage failure occurring for a brief period during the disengaging operation. For this purpose, provision is made to assign to the drive a securing means by means of which, upon exceeding a predeterminable moment difference between the drive shaft and the driven shaft, the torque supplied by the drive can be reduced to a predeterminable amount, before transmission to the driven shaft, by the formation of a counteracting moment of friction.

Title: Steering system for a vehicle
Inventor: NAGAOKA MITSURU
IPC: B62D6/00
Filed: 1994-03-25
Abstract: A steering system for a vehicle has a secondary wheel steering mechanism which steers the front wheels or rear wheels independently of the steering wheel. A main control system calculates the control variable on the basis of the difference between the actual yawing angle and the desired yawing angle which controls the secondary wheel steering mechanism with the control variable in such a way that the actual yawing angle converges with the desired yawing angle. A neural network control system has a neural network which has learnt control variables for the wheel steering angle as a function of a state variable of the vehicle. The control of the wheels is switched over from control by the main control system to control by the neural network control system when it is determined that the operating state of the vehicle is outside the range within which the stability of the vehicle is ensured by the wheel steering control by the main control system.
