Title: Verfahren zum steuern der strahlformung eines nachrichtensignals in einem funk-kommunikationssystem
Inventor: RAAF BERNHARD
IPC: H04B7/06
Filed: 2002-01-18
Abstract: Zum Steuern der Strahlformung eines von einer Basisstation (BS) an eine Teilnehmerstation (MSk) eines Funk-Kommunikationssystems ausgestrahlten Nachrichtensignals ermittelt die Teilnehmerstation (MSk) Werte eines Strahlformungsparameters und überträgt sie als Rückkopplungsinformation an die Basisstation (BS). Dabei werden nacheinander ermittelte Werte des Strahlformungsparameters unter Zugrundelegung einer Mehrzahl von jeweils unterschiedlichen Intervallteilungen des Wertebereichs des Parameters quantisiert. Die erhaltenen Quantisierungswerte werden an die Basisstation übertragen, und die Basisstation setzt, sofern nacheinander Quantisierungswerte des Parameters übertragen werden, die nichtdisjunkten Intervallen entsprechen, einen Parameterwert aus der Schnittmenge dieser nichtdisjunkten Intervalle für die Strahlformung ein.

Title: Printing washable plastics book pages using - ink contng a vinyl polymer
IPC: B44D3/18
Filed: 1968-10-23
Abstract: Books for children with washable pages are made of hard PVC-material. They are printed with water-insoluble plastics colours so that the child can fill in the pictures with water colours and wash them off for re-use. This printing process gives the book an unpleasant odour. A satisfactory method to be used for this purpose is to print by photogravure process with inks which contain as a binding agent a vinyl polymer with polar groups which are firmly attached by part-dissolution. The printing method may also be copper gravure or flexo printing and the ink may include a solvent mixture.

Title: Continuous heat-treatment of cold-rolled steel strip - two-stage process for mass prodn of deep-drawing steel
Inventor: HIRATA HIROMASA
IPC: C21D9/52
Filed: 1973-04-26
Abstract: The strip travels through shears and/or uncoilers to second set of shears and then to a welding unit to make continuous strip, which goes through electrolytic cleaning. After cleaning, the strip is fed over rollers on two moving trolleys; the length of these loops is adjustbale so that, even when the flow of strip is halted by the welding operation, it can still be fed continuously through a furnace where it is held for 20-30 seconds at 700-720 degrees C. The strip then enters a chamber, filled with non-oxidising gas, contg. flying shears and coilers for hot-coiling, the temp. of this chamber being held constant. The coils are then fed through a second furnace on trolleys wehre they remain 1 1/2 -2 hrs. to permit adequate grain growth, and they pass into a cooling zone for cooling through the critical temp. range. The next stage comprises a second chamber, filled with a non-oxidising atmos., where the rolls of strip are uncoiled and pass through shears and a welder to reform the continuous strip, which then travels through a press. spray cooler to a cold-rolling unit, shears and a coiler.
