Title: Colour television projection device with automatic correction of picture geometry and colour convergence
Inventor: MEYER GERALD DIPL PHYS
IPC: H04N9/31
Filed: 1987-09-23
Abstract: Television projection with three separate picture tubes gives rise to the problem of bringing these three partial images precisely into a congruent position on the screen. In the normal case, this can be achieved only by laborious manual setting. To be able to influence the geometrical properties of the projected partial images, for each picture tube there are used not only the necessary main deflection coils but also additional corrective deflection coils, the magnetic field of which is superimposed on the main magnetic field. The automatic measurement of the geometry of each individual projected chromatic component permits the calculation of errors, which can be used for an automatic correction of the picture geometry. By using novel circuitry, the influencing of the geometry takes place exclusively by means of the in any case existing main deflection coils; auxiliary deflection coils are not required. The generation of the necessary correction signals is possible by means of a digital memory, which is read out synchronously with the picture build-up and the output signal of which passes through a digital-to-analog converter. The invention has applications in television technology. The circuitry used for the horizontal deflection can, in addition, be employed in electron microscopy and electron-beam lithography.

Title: Slip-controlled hydraulic motor vehicle brake system
Inventor: RUPPRECHT KURT
IPC: B60T8/44
Filed: 1987-11-04
Abstract: The invention relates to a hydraulic motor vehicle brake system with two diagonally divided brake circuits and one open antiblocking control device which operates according to the feed principle and has control valves which are connected ahead of the wheel brakes and contain inlet valves and outlet valves. In the pressure lines leading to the rear wheel brakes, simple, i.e. non-switchable, pressure-dependent brake pressure distributors are arranged ahead of the control valves in such a way that their reducing or limitting function is automatically effective only if, and for as long as, the wheel brakes are statically supplied with brake pressure from the main brake cylinder, but is not effective if, and for as long as, they are dynamically supplied with brake pressure from an auxiliary pressure supply system of the antiblocking system. <IMAGE>

Title: Method for stripping cooling water from rolls in rolling trains for steel and a stripper for carrying out the method
Inventor: GOERGEN OTTO DR ING
IPC: B21B27/10
Filed: 1987-11-16
Abstract: The water cooling of the rolls in the region of the roughing trains with their slow entrance speeds leads to excessive cooling of the hot surface of the rolled billets by the cooling water flowing off. In the case of steels prone to cracking, the relatively low rolling temperatures bring with them the disadvantage of surface crack formation, making it very difficult to roll these steels without rolling defects. The aim of the invention is to roll even steels prone to cracking without the quenching of the surface of the rolling stock by the water cooling system so that they are free from surface defects. The solution to the problem consists in that strippers for stripping cooling water from rolls are installed in rolling trains for steels, these strippers preventing the cooling water from flowing off the top roll onto the hot rolling stock and contributing to a considerably smaller temperature loss of the rolling stock.

Title: Process and apparatus for the thermal-catalytic exhaust air purification of solvent-containing exhaust air
Inventor: KOCH CHRISTIAN DR ING
IPC: B01D53/86
Filed: 1988-04-07
Abstract: The invention relates to the process and the apparatus for the thermal-catalytic exhaust air purification with heating of the air upstream of the catalyst via a heat recovery system and burner. In the special catalyst system spinel, formed from the components lanthanum, cerium and cobalt, on ceramic honeycomb bodies which have previously been coated by a wash coat, high final purities of the thermal-catalytically purified air can be achieved. As a result, according to the invention additional measures are necessary in order to prevent contamination of the purified air due to overflow leaks from the unpurified air via extraction and flushing air fans. The lower reaction temperature of the catalytic exhaust air purification in comparison to the non-catalytic exhaust air purification makes possible the use of a greater number of exhaust air purification systems which would cause an excessive energy consumption without the use of catalysts.

Title: Method for controlling communication switching systems, particularly telephone branch exchanges
IPC: H04Q11/04
Filed: 1988-08-29
Abstract: The aim of this method is that in the case of overloading or a failure of central processors, an immediate replacement is available so that high operational reliability is given even in the case of large communication switching systems. The traffic-handling capacity of a communication switching system should not be reduced significantly even when central sections fail. A number of space-division switching stages of similar construction are provided which are controlled by in each case their own central processor. The space-division switching stages have access to all access unit groups via separate buses. A number of access unit groups are combined in such a manner that the connections coming from these are predominantly switched via a bus and via a space-division switching stage associated with the latter, which is set by a central processor responsible for it. In the event of a failure or overloading of this central processor, the switching-through of connections is taken over by another central processor, in which case a different bus and a different space-division switching stage are then used. In the event of a failure or of the overloading of a central processor, the traffic-handling capacity of a communication switching system is not significantly impaired and the operational reliability is drastically increased.
