| 20110037551 | Oil Filled Transformer With Spacers and Spacers for Separating and Supporting Stacked Windings - An oil filled high power transformer for high voltages with coils. The transformer including a number of stacked layers of, in the main concentric, insulated conductors forming transformer coils. The winding layers are separated by spacers. One or more spacers are provided with at least one integrated electrical discharge barrier extending off the central body of the spacer in the vicinity of the area where the spacer is in contact with a winding. Breakdown along spacer and alongside the spacer-oil interface is reduced getting improved breakdown strength of the oil filled transformer. | 02-17-2011 |

| 20090200247 | FILTER ELEMENT WITH COATING FOR SURFACE FILTRATION - A method for filtering out foreign particles from a cooling lubricant used in a process of machining a workpiece includes providing an inherently stable, flow-porous filter element. The filter element comprises a porous main body made of joined plastics particles and having an afflux surface and a porous coating on the afflux surface for surface filtration. The porous coating first component particles and/or fibres, second component anti-adhesion particles to mitigate the adhesion of filtered out material to the porous coating and to facilitate cleaning of the filter element, with the first component particles and/or fibres and the second component particles being mixed in the porous coating, a solidified inorganic binder, and a set adhesive. The solidified inorganic binder and the set adhesive bind the first component particles and/or fibres and the second component particles to each other and to the porous main body. The cooling lubricant is first passed through the porous coating and thereafter through the porous main body of the filter element. | 08-13-2009 |
