Abstract: A lamp heat extractor device for lowering the cold spot temperature of a fluorescent lamp includes a base portion adapted to be attached to a heat conductive portion of the fluorescent lighting fixture proximate the fixture's lamp socket or sockets, and an extended sleeve end portion thermally connected to the base portion by a conductive connector portion. The conductive connector portion positions the extended sleeve portion so that it contacts the cold spot end of the fluorescent lamp or lamps held by the lamp sockets of the fixture to allow heat transfer to the fixture housing to which the heat extractor device is attached. Suitably, the outer surface of the extended sleeve end portion of the heat extractor device can have a plurality of radially extending fins for increasing surface area for heat radiation from the extended sleeve portion, thereby increasing the overall heat extracting efficiency of the device.

Abstract: Fluorescent lighting fixture modules for indirect lighting of interior spaces, each module including at least one, and preferably a pair of side-by-side parallel linear indirect fluorescent lighting fixture elements suspended at fixed grid pattern locations beneath the ceiling of the open interior space. Each of the linear indirect lighting fixture elements is preferably no greater than approximately six feet in length with a suitable length being somewhat greater than four feet where a four foot lamp is used. Where the fixture elements are provided in pairs, each is suspended below the ceiling at its fixed grid location by a suitable hanger structure with a preferred overall fixture module width of approximately four feet.

Abstract: An rf pulse compressor has a single high Q cavity resonator fed by a four port hybrid coupler which is connected to the resonator at coupling ports located at the intersection of two of the resonator's orthogonal axes with the resonator cavity walls. The hybrid coupler divides pulse power from an rf pulse power source and excites two space and phase orthogonal modes in the single cavity, the stored energy of which aids in producing compressed pulses at the output of the hybrid. On-axis perturbations in the cavity walls can be used to lock the orthogonal orientation of the modes excited in the cavity.
Abstract: A mobile cargo container handling buffer crane having a bridge crane mounted thereon for transferring cargo containers between a ship and land transportation with an intermediate transfer position at which a suspended container can be noninvasively inspected by a longitudinally reciprocating container traversing nonintrusive inspection apparatus.
