Abstract: PCT No. PCT/NL93/00125 Sec. 371 Date Dec. 12, 1994 Sec. 102(e) Date Dec. 12, 1994 PCT Filed Jun. 10, 1993 PCT Pub. No. WO93/25485 PCT Pub. Date Dec. 23, 1993.A system for purifying nitrogenous waste water by biological nitrification and denitrification, comprises at least two essentially separated reactor chambers, a liquid supply (4) and a liquid discharge (5). The first, aerated reactor chamber (1) is provided at the top with an overflow to the second, oxygen-depleted reactor chamber (2). The oxygen-depleted reactor chamber (2) is divided at the top into a degassing chamber (7) and a settling chamber (8) having an overflow (9) to the liquid discharge. The first reactor chamber is provided with an air supply (11, 18) and an air discharge (12) located above the supply. The first reactor chamber may be partly divided into a riser (14) and a downcomer (15) which allow, as a result of the air supply, mass circulation to take place in the aerated reactor chamber. According to the process, waste water with bacterial sludge on a carrier circulates alternately through the oxygen-depleted and the aerated reactor chambers, whereafter it is separated from the sludge and the sludge is returned to the reactor.

Abstract: In the bulb of a color cathode ray tube, a flat glass panel having a substantially uniform thickness is used. The flat glass panel has a glass wall which extends in a substantially vertical direction from the flat glass panel. The glass wall adheres to a funnel, which includes a neck portion in which an electron gun is disposed, by means of a glass adhesive so as to form the bulb. A shadow mask on which a number of apertures are formed is fixed to a frame with an appropriate tensile stress and the frame is mounted on the glass wall. The shadow mask is disposed at a position close to the phosphor screen formed on the inner surface of the flat glass panel, facing thereto. On the outer surface of the flat glass panel, a resin film comprising at least one layer is attached by means of an adhesive. The resin film has appropriate mechanical, optical and electrical properties with which the flat glass panel should have. Thus, various properties of the flat glass panel can be controlled. As a result, it makes it possible to provide a high-performance color cathode ray tube using a thin flat glass panel which has a sufficiently large mechanical strength and desirable optical characteristics, capable of displaying images with high resolution and high color tone without distortion over the entire front surface.

As a result, it is possible to obtain high-class laminated lumber without knots on three or four sides by using natural wood with knots with a high product yield. 
     In the method of making the laminated lumber, a plurality of prismatic wood 11 to 15 are arranged in the transverse direction, outside pieces of the prismatic wood 11 and 15 have no knots, inside pieces of the prismatic wood 12 to 14 which have inside knots 16 to 19 lengthwise are rotated such that the knots 16 to 19 of the inside pieces of the prismatic wood 12 to 14 are present in the transverse direction. By arranging the prismatic wood in this way, there is substantially no knots on the four sides of the laminated lumber. An adhesive is applied between the prismatic wood in this condition, and the prismatic wood is bonded together by pressurization, and the surface is smoothed in due course.

Abstract: 2.1 The known technical solutions are based on the transmission of the 16-kHz-frequency pulse to the telephone subscriber, its evaluation and the output of a corresponding charge information item. Since such a charge information item is based on adding together all transmitted pulses, interference on the transmission path will falsify the charge information. 2.2 According to the invention, this defect is eliminated by an information device (IE) arranged at the exchange, which is directly connected to the subscriber-individual tariff unit meter (TEZ) and which meters the original tariff information items of the corresponding tariff unit meter (TEZ). The respective current tariff information item is transmitted to the telephone subscriber on request. 2.3 If errors occur during the transmission, the charge information will also be falsified but, in contrast to the known solutions in which the errors are added together, the inquiry for further charge information will lead to a correction of the charge information in the solution according to the invention. <IMAGE>

Abstract: A process of providing a disposable core for use in die casting processes. A salt material is molten and cast into a core of a desired configuration under exacting conditions. The fluidity of the molten salt is controlled enabling casting the salt material into a core by die casting methods. The die casting method provides a core with a high surface finish and strength. The core is evenly cooled subsequent to it being cast and is maintained at an elevated temperature to maintain its surface finish and structural integrity. The cast core is inserted into the dies of a metal die casting machine to facilitate casting a metal product having internal forms not otherwise attainable. The core is removed from the metal product by simply dissolving and flushing the core out of the casting. The salt material may be reclaimed by a de-salination process for further use.
