Abstract: A seal assembly for sealing a shaft bearing includes a seal housing, first and second seal rings retained by the seal housing, an annular chamber formed between the first and second seal rings and a connecting channel configured to place the annular chamber in fluid communication with a bearing-housing-side oil space. When the seal assembly is installed on a shaft, the connecting channel is configured to permit a fill-level equalization between the oil space and the annular chamber when the oil space is filled to a first possible fill level (N1) and to prevent the fill-level equalization between oil space and annular chamber when the oil space is filled to a second possible fill level (N2).

Abstract: An insulated high-temperature wire superconductor includes a wire of a non-insulated high-temperature wire superconductor, the width of which is at least 10 times its thickness and in which a high-temperature superconductor is introduced into a matrix or is applied to a substrate. The wire is provided with an electrically non-conducting insulating layer on both sides such that the two insulating layers have an insulating edge width in a range from 2 mm to 200 mm which projects in relation to the wire.

Abstract: A seal apparatus, for sealing around a rotating shaft such as a propeller shaft of a watercraft between the exterior water and an interior lubricant space, includes a multiple seal arrangement with plural seal rings forming seal chambers therebetween, and plural fluid medium lines supplying and/or returning a respective fluid medium to a respective seal chamber. A section of a first medium line is formed as an axial passage through a housing of the apparatus, and a section of a second medium line is formed by a pipe arranged within the axial passage in the housing. A method of making such an apparatus especially by retrofitting an existing seal arrangement involves inserting a pipe into an axial passage in the housing in order to establish two medium lines through the housing where there was previously only one medium line.

Abstract: A seal arrangement for sealing around a rotating shaft that passes through a ship bulkhead includes an expandible and contractible seal ring made of several seal ring segments, and radial actuators that engage the seal ring segments and can be power-activated, e.g. with a pressure medium, to pull the seal ring segments radially outwardly, thereby expanding the seal ring to a larger diameter spaced away from the shaft. When the radial actuators are not activated, the biasing force of springs contracts the seal ring segments to a smaller diameter, to establish sealing contact of the seal ring on the shaft. In normal operation a control unit activates the actuators, but if sensors detect a power failure or water in the ship, or a manual switching is triggered, then the seal arrangement contracts under spring force into the sealing condition with the seal rings sealing against the shaft.

Abstract: A transistor device structured such that the bulk, gate, drain, and source are all accessible from all four edges of the device and such that current distribution is uniform over the device is provided. The transistor is created with a four-metal CMOS process. A bulk connection can be made with Metal 1, which is all around the device. A gate connection can be made with Metal 2, which is all around the device. Additionally, a drain/source connection can be made with Metal 3, which is all around the device. A source/drain connection can be made with Metal 4, which is all around the device. Source/drain connections are made with two or more evenly distributed via stripes to connect the source/drain parts of the transistor fingers. The transistor structure may be used to create an array of transistors for a high power output stage, with the transistors arranged in a checkerboard pattern. The connections of each transistor are automatic by abutting edges of the transistors.

Abstract: A cooking appliance includes a cooking space, a microwave generator device and at least one coaxial transmission line or strip transmission line within the cooking space. The transmission line is connected to the microwave generator device, and is used to outcouple microwave radiation produced by the microwave generator device to the cooking space. The at least one coaxial transmission line and/or strip transmission line may be integrated in at least one component of the cooking appliance in the form of a post or a fixed holder within the cooking space or in at least one accessory which can be introduced into the cooking space. The holder may include a hanging rack, a mobile oven rack or a mobile plate rack to hold insertable cooking containers, plates, sheets and/or pans.
