Title: A metal-enclosed high-voltage switching system with a current transformer
Inventor: SUERMANN BERTHOLD
IPC: H01F38/28
Filed: 1994-04-29
Abstract: In a current transformer (1) within a capsule housing (6) of a high-voltage switching metal-enclosed high-voltage switching system, between the secondary winding and the high-voltage line (10) there is a first tube, in particular a supporting tube (2) that is conductively connected at its first end with the capsule housing (6) and which at its second end is electrically connected to a second tube (8). The second tube lies against the inside wall of the capsule housing (6), with an insulating layer (9) between them. A closed conductive loop is avoided because of the insulating layer (9) and because of the fact that the second tube lies on the inside wall of the capsule housing the current transformer is effectively sealed against travelling waves within the capsule housing (6).

IPC: G02F1/13357
Filed: 1996-10-04
Abstract: An optical device for collecting light and selectively outputting or concentrating the light. A wedge layer has an optical index of refraction n1, and top, bottom and side surfaces intersecting to define an angle of inclination .slzero.. A back surface spans the top, bottom and side surface. A first layer is coupled to the bottom surface of the layer and has an index of refraction n2. The first layer index n2 causes light input through the back surface of the layer to be preferentially output into the first layer. A second layer is coupled to the bottom of the first layer and selectively causes output of light into ambient. Additional layers, such as a light polarization layer, a polarization converting layer and a post LCD diffuser layer can be used to make preferential use of polarized light or diffuse light having passed through the LCD layer to enhance viewing of the output light.
