Abstract: The disclosed technology generally relates dielectric materials and methods of forming the same, and more particularly to a combination of co-fireable dielectric materials that can be attached to each other without the use of adhesives. In an aspect, a composite article comprises a magnetic portion comprising a nickel zinc ferrite. The composite article additionally comprises a non-magnetic portion contacting the magnetic portion, the non-magnetic portion comprising a spinel-structured oxide comprising Mg2-xAl2xTi1-xO4 and having a dielectric constant between about 7 and 14, wherein 0<x?1.

Abstract: Disclosed herein are embodiments of low temperature co-fireable barium tungstate materials which can be used in combination with high dielectric materials, such as nickel zinc ferrite, to form composite structures, in particular for isolators and circulators for radiofrequency components. Embodiments of the material can include flux, such as bismuth vanadate, to reduce co-firing temperatures.

Abstract: A method of forming a composite material for use as an isolator or circulator in a radiofrequency device comprises providing a low temperature fireable outer material, the low fireable outer material having a garnet or scheelite structure, inserting a high dielectric constant inner material having a dielectric constant above 30 within an aperture in the low temperature fireable outer material, and co-firing the lower temperature fireable outer material and the high dielectric constant inner material together at temperature between 650-900° C. to shrink the low temperature fireable outer material around an outer surface of the high dielectric constant inner material to form an integrated magnetic/dielectric assembly without the use of adhesive or glue.

Abstract: A novel and unique bicycle seat for a rider includes a base having a base top surface with an inflatable bladder having a bladder top surface. The inflatable bladder is disposed on the base top surface and the base top surface and the bladder top surface together form a seat contour profile. A pump is connected to the inflatable bladder to introduce fluid media therein with a release valve fluidly connected to the bladder to permit fluid media to exit therefrom. Also, the bicycle seat of the present invention can be configured to be in the form of a cover to be retrofitted to an existing bicycle seat. In this configuration, the cover includes a base with a structure for securing it to the existing bicycle seat. For example, this structure can be a skirt of material or other releasable type of structure.

Abstract: A recovery process and apparatus employing a pressure water washer to process wood chip wash water, to separate pin chips from sand and dirt contained in the wash water. Wash water from a chip wash system is supplied to a pressure washer having a cylindrical screening basket and a rotor positioned within the basket. The screen basket has holes of 1-3 mm which allows dirt and sand to pass but retains pin chips. The wood fiber pin chips on the way to the accepts outlet thus do not pass through the screen basket. Additional water may be added to the pressure washer to balance the flow of water along and through the screen basket.
