Abstract: The invention concerns an endovascular implant comprising a biodegradable material and having a tubular main body which is open at the ends and which is dilatable from an unexpanded condition into an expanded condition. The implant is so designed that when the implant in the expanded condition is subjected to a radially acting compression pressure in the range of between 5 and 30 kPa (0.05-0.3 bar) a cross-sectional area of the implant is reduced to 70% or less of the original cross-sectional area, or an internal volume of the implant is reduced to 70% or less of the original internal volume.

Abstract: A damage control system for monitoring, suppressing and eliminating leakage damage, fire damage and/or ABC contamination after collisions, running aground, the effects of weapons, etc., has an automation and monitoring system for system failures, voltage outages and equipment failures and has an operating station at which a perspective layout of the ship, which represents the rooms of the ship, can be displayed. To obtain a picture of the situation more rapidly after a collision, running aground or the effects of weapons, an alarm unit is installed in each room or in each of a group of rooms of the ship allocated together, these alarms cooperating with the damage control system, so that when deployed, the display of the corresponding room and/or group of rooms allocated together undergoes a color change in the perspective layout of the ship.

Abstract: For the integration of an npn bipolar transistor with a hetero bipolar transistor, a placeholder layer is generated in a base region of the hetero bipolar transistor after structuring a collector structure for both types of transistors, wherein the placeholder layer is not present in a base region of the bipolar transistor. After generating the base of the bipolar transistor, the base of the bipolar transistor is covered, whereupon the placeholder layer is removed and the base of the hetero bipolar transistor is generated in the places where the placeholder layer has been removed. The emitter structure is again generated equally for both types of transistors so that an integrated circuit results which includes bipolar transistors and hetero bipolar transistors whose collector structures and/or whose emitter structures consist of identical production layers. Thus, space-saving and cost-effective integrated circuits may be produced benefiting from the advantages of both types of transistors.

Abstract: A method for stretch breaking fibers to produce a staple yarn and operating a staple fiber spinning machine that enables the production of a plurality of products of lot size smaller than a large denier tow product. The process includes at least two break zones and a consolidation zone downstream from a second break zone to form a staple yarn. The filaments are broken in a second break zone downstream from the first break zone by increasing the speed of the fiber fed into the process.

Abstract: A method for producing bipolar transistors with the aid of selective epitaxy for producing a collector and base. The method includes widening the area of the base either by the isotropic etching of the conductive layer or by the oxidation of the conductive layer and by the subsequent removal of the oxide layer. This widening of the area of the base prevents the occurrence of short-circuits between the emitter and the collector during the subsequent production of the base.

The invention is distinguished in that the combination is compressed to varying degrees along the longitudinal axis of the combination.

Abstract: The invention relates to the use of linear and/or branched fatty alcohols containing at least 12 carbon atoms in the molecule and/or to the use of mixtures of such fatty alcohols with carboxylic acid esters as a lubricating additive in water-based drilling fluids for their use in geological exploration by drilling. The fatty-alcohol-based lubricants or lubricant systems are particularly suitable for use in water-based alkali metal silicate drilling muds which are known to be distinguished by comparatively high pH values. The additives according to the invention combine their lubricating effect with a foam-suppressing effect, i.e. prevent unwanted foaming.

The covering includes an access slit through which the cavity can be accessed, and is sufficiently flexible so that the slit can be opened to access the cavity. A pouch can be attached to the covering material along the slit, so that a purse-like pouch is created for holding personal items and/or excess electrical wiring. A zipper or closure device can be used on the access slit. In one form, the skin is releasably attached with hook-and-loop material, so that a corner of the skin can be pulled loose for accessing the cavity.
