Abstract: In the transmission of digital signals in time-division multiplex via a transmission link with repeater stations at which time slots are either only dropped are also reoccupied, the problem arises of continuing to maintain the information transmission even with an alarm triggered in a repeater station. The invention provides for a bypass circuit (11) via which the repeater station is bypassed when an alarm is triggered in it. If a reoccupation of the time slots is intended, the bypass circuit (11) in this arrangement can send a message to the neighbouring repeater stations and/or the line terminating device for allowing the reallocation of time slots which have not been reoccupied in the repeater station. If the time-division multiplex signal contains a service channel, messages can be sent to the neighbouring repeater stations and follow-up measures initiated via this channel. <IMAGE>

Abstract: Pharmaceutical compositions useful in the treatment of ophthalmic inflammation and methods of treating ophthalmic inflammation with those compositions ar disclosed. The compositions contain a combination of a glucocorticoid and an angiostatic steroid. The angiostatic steroid substantially prevents any significant increases in intraocular pressure which might otherwise be experienced by the patient as a side effect of the glucocorticoid component of the compositions. The therapeutic interaction of the two components therefore allows the potent anti-inflammatory properties of the glucocorticoids to be utilized without fear of elevating intraocular pressure.

Abstract: Lamps, in particular lamps having elongated fields for illuminating working spaces, must have minimum requirements for glare limitation which is determined by the screening angle ( alpha ). Because of the prescribed lamp dimensions, it is not possible to achieve the required minimum screening angle in modern lamps of this type. In order to achieve a sufficiently large screening angle ( alpha ) with such lamps, it is proposed to provide the cover plate (A1, A2), which seals the light exit opening and is made from transparent material, with rim regions (1, 5) which have a prismatic profiling of suitable dimensioning, by means of which the screening angle ( alpha ) is appropriately enlarged. In a further development, the cover plate (A2) can additionally have on the inside a central region (3) with prismatic profiling of appropriate dimensioning in order to achieve a deep indentation in the light distribution curve (LVK2) in the angular range about 0 DEG . <IMAGE>

Granted: 1993-09-01
Abstract: The invention relates to an apparatus for generating steam by combining hydrogen and oxygen. It comprises a combustion chamber for combining hydrogen and oxygen and a downstream injection cooler, in which the steam generated in the combustion chamber and having a very high temperature is brought by injection of feedwater to the parameters suitable for feeding into the steam turbine, with a simultaneous increase in the steam mass flow. To provide an apparatus which allows in a technically simple manner the high temperatures of 3000 DEG C, arising as a result of the oxidation of hydrogen, to be controlled and the resulting steam to be changed with respect to its parameters, especially temperature and pressure, in such a way that it can be fed to a downstream steam turbine, the injection cooler is formed by a double-walled cylinder (1), on whose inside wall (2) a lining of an axially extending tube bundle is located. The feedwater is fed to the tubes (7) of the tube bundle at the end facing the combustion chamber, the other end of the tubes (7) being connected to the annular space (6) of the double-walled cylinder (1). In a part- region, some tubes (7) of the tube bundle form unlined surfaces (11) by means of radial deflections 7a, on which surfaces injection devices (12) for the feedwater are located in the inside wall (2) of the cylinder (1).

Abstract: A wear or corrosion resistant coating is produced on a metal or ceramic object. A coating material in powder form consisting of hard alloys, metallic alloys, inter-metallic compounds, cermets or ceramic materials is bonded to the surface to be coated by an organic binder. The resulting bonded layer is heated to decompose the binder, some of which may contribute carbon, and is then further heated in conjunction with the application of isostatic super-atmospheric pressure to consolidate the resulting coating. During the latter heating step desirably no liquid phase is produced but the temperature is as high as possible, this being achieved by choice of the powder components and process conditions. A suitable coating material comprises by weight 6 to 25% of chromium, molybdenum, tungsten, tantalum, niobium, titanium, hafnium or zirconium, or a mixture thereof, 0 to 2% of carbon (ie in addition to carbon from the organic binder), 0 to 5% boron, or equivalent amounts of silicon or iron, 0 to 3% silicon, 0 to 10% aluminium, 0 to 1% of a rare earth element/s such as cerium and yttrium, particulate material such as tungsten carbide, the balance being nickel, cobalt or iron.
