摘要:
A radially-sealing ring has a sealing element of a non-elastomeric plastic, preferably of PTFE, planar, annular disk having plane-parallel surfaces held at its outer circumference in a stiffening ring and cold flexed in the axial direction to form a cuff at its inner circumference which engages the shaft with bias. The disk has a thickness of from 0.3 to 0.8 mm and an inside diameter approximately 1.5 to 7 times its thickness less than the diameter of the shaft. The distance between the shaft and the line about stiffening ring where the disk is held is 2 to 7 times as great as the thickness of the disk. The radially-sealing ring is preferably for sealing the crankshaft of a two-cycle engine.

The inside of a planar, annular disk having a thickness of from about 0.8 to about 2 mm is cold flexed into a cylindrical, sealing stub about a shaft. For this, the inside diameter of the disk before cold flexing about the shaft is from about 1 to about 6 times the thickness of the disk less than the diameter of the shaft. A stiffening ring is sealingly attached about the outside of the disk with the line of the innermost attachment therebetween being from about 1.1 to about 4 times the thickness of the disk from the surface of the shaft.

A manufacturing method provides a semiconductor device with a substrate layer and an epitaxial layer adjoining the substrate layer. The epitaxial layer includes first columns and second columns of different conductivity types. The first and second columns extend along a main crystal direction along which channeling of implanted ions occurs from a first surface into the epitaxial layer. A vertical dopant profile of one of the first and second columns includes first portions separated by second portions. In the first portions a dopant concentration varies by at most 30%. In the second portions the dopant concentration is lower than in the first portions. The ratio of a total length of the first portions to the total length of the first and second portions is at least 50%. The uniform dopant profiles improve device characteristics.

A medical imaging system has a modality for acquiring images, components for processing the images, a communication linkage for the transmission of the images and memory arrangement for storing the images with a number of separate memory systems. The memory arrangement includes a control system which causes successive image datasets to be stored in separate memory systems.

A sorting installation for useful products is proposed, which serves in particular to sort out reusable packaging materials. In order to achieve the sorting-out of individual types of packaging with maximum efficiency, the sorting-out of individual monofractions is undertaken, on one or more manual sorting sections, onto a collector conveyor belt which is connected in parallel, the content of which, after sorting-out is complete, is introduced into an associated bunker.

A hermetically sealed electrical component. A conductor passes through a metal body member in which it is sealed by a glass-to-metal seal, extending to the electrical component. The metal body member is soldered or brazed to a support plate. A cap enclosing the component is cold pressure welded to the support plate.

The present invention relates to a container comprising a glass vessel and at least one plastic top on the glass vessel, characterised in that the glass vessel is substantially circular in cross-section and has a floor and a peripheral side wall, the upper circumferential edge of the peripheral side wall being formed as an annular bead extending outwards, and that a plurality of notches extending radially are provided on the upper circumferential edge, at least in the outer portion thereof, and that the plastic top is substantially ring-shaped with a side wall and an inner ring spaced apart from the upper and lower edges of the ring shape and having upper and lower sides, the side wall having a peripheral snap-in projection beneath the inner ring, projecting inwardly, which, when the glass vessel is connected with the plastic top, is snapped in behind the annular bead of the glass vessel, wherein rib-like lands project radially on the lower side of the inner ring in the area of the connection between the inner ring and the side wall, their number corresponding to that of the notches in the glass vessel, and which lands engage in the notches of the glass vessel when the glass vessel and the plastic top are connected.
摘要:
A method is proposed for recovering valuable substances, particularly from construction site wastes and industrial trash as well as a system for implementing the method in which the essential sorters are disposed in a closed container which can be placed onto an elevated foundation. The foundation is formed by intersecting walls which simultaneously serve as partitions for various bunkers.
