Abstract: A high performance rolling element bearing (5) which is particularly suitable for use in a cryogenically cooled environment, comprises a composite cage (45) formed from glass fibers disposed in a solid lubricant matrix of a fluorocarbon polymer. The cage includes inserts (50) formed from a mixture of a soft metal and a solid lubricant such as a fluorocarbon polymer.

Abstract: A corner post formed of two elongated members, which may be molded plastic, each member has a decorative ridge on the front face, a part of one ridge on one of the members lying along an edge thereof and defining a flange having an inner face which abuts an adjacent edge of the other member and covers the crack between the members. The ridge on the other member is spaced from its edge, the same distance as the first ridge is spaced from the front face of the other member. Additional symmetrically spaced ridges may also be provided.

Abstract: Tuning varactor circuitry is disclosed for a dielectric resonator stabilized oscillator (2). A varactor diode (22) is electrically connected in a loop (24) with an RF bypass capacitor (26), and the voltage across the diode is varied. In a first embodiment, first and second dielectric substrates (36, 38) face each other along the plane of the loop (24), with the loop (24) therebetween. In another embodiment, the loop (24) is around a peripheral side wall (52) of the dielectric resonator substrate (46). In another embodiment, the loop (24) is formed on the same surface (54) of a microstrip circuit substrate (56) with a transmission line (10).
