  • Publication number: 20190164729
    Abstract: RF isolation for power circuitry includes one or more ferrite cages surrounding a pair of coils, one coil connected to power input, and the other coil connected to a load such as a heater. The ferrite cage provides universal isolation for the coils, avoiding the necessity of specially tuned filters or more complicated coil arrangements. A pair of dielectric discs support respective coils. In one aspect, the ferrite cage is constituted by ferrite pieces which fan out from a central portion of the dielectric discs and are connected at an outer periphery of the dielectric discs, and at the central portion of the dielectric discs. In one aspect, the fanned-out ferrite pieces comprises either manganese-zinc or magnesium-zinc ferrites, and the ferrite pieces connecting the fanned-out ferrite pieces comprise nickel-zinc ferrites.

  • Patent number: 5771378
    Abstract: An associative text search and retrieval system uses one or more front end processors to interacting with a network having one or more user terminals connected thereto to allow a user to provide information to the system and receive information from the system. The system also includes storage for a plurality of text documents, and at least one processor, coupled to the front end processors and the document storage. The processor(s) search the text documents according to a search request provided by the user and provide to the front end processor a predetermined number of retrieved documents containing at least one term of the search request. The retrieved documents have higher ranks than documents not provided to the front end processor. The ranks are calculated using a formula that varies according to the square of the frequency in each of the text documents of each of the search terms.

  • Patent number: 4112585
    Abstract: A level indicating instrument permitting simultaneous reading in two horizontal and/or vertical planes, one of which planes may be preset to any desired deviation from the horizontal. A pair of straight-edges perpendicular to each other along their long axis are coupled to a bubble indicator of the bull's-eye type. The bubble indicator may be rotated relative to the straight edges and set to indicate vertically or horizontally or any desired preset angle between vertical and horizontal.
