A pair of coupled chopsticks for grasping food is disclosed. The coupling intermediate each of the chopsticks is formed by a pair of coil springs. Each of the coil springs includes arms extending therefrom, each arm of each coil spring being attached to one of the chopsticks. A clamp secures the two coil springs to each other in axial alignment. The axis of the pair of coil springs represent the point about which the chopsticks pivot. The arms of the coil springs maintain the chopsticks aligned ...

Controls for cameras adpated to use coupled and non-coupled objectives interchangeably. An electrical circuit is provided for utilizing a variable resistor with a coupled objective and direct light measurement through a stopped-down diaphragm with a non-coupled objective, these different operations being determined by a manually operable switch. In the event that a non-coupled objective is mounted on the camera and this latter manually operable switch is not positioned to directly measure light ...

Linear, branched and/or cross-linked acyl coupled polymers of quinone-coupled polyphenylene oxides are described which comprise di- and/or tri-functional acyl radicals coupled with polyphenoxy radicals, said polyphenoxy radicals being derived from quinone-coupled polyphenylene oxides having an average hydroxyl group per molecule value greater than zero including 2.0 or less. The resulting polyphenylene oxides can be used to prepare various articles of manufacture.

A waveguide filter switch, including a waveguide transmission path for electromagnetic energy. At least one series resonator filter positioned in shunt with the transmission path. At least one coupling aperture in the waveguide for coupling the at least one series resonator to the waveguide. A switching positioned across the coupling aperture and having an open state wherein the coupling aperture is electrically open to provide for coupling the series resonator to the waveguide and having a clos...

An improved optical scanner includes a semiconductor charge coupled shift register. An overflow reservoir is operably coupled to respective bits of the shift register in accordance with one aspect of the invention to receive electrical charge which is in excess of the storage capability associated with each bit to prevent "blooming." In a different aspect of the invention, an optically inactive semiconductor shift register is coupled with light sensitive regions which are adjacent respective bit...

This disclosure includes a four pole bandstop filter coupled to a five pole bandpass filter tuned to an adjacent band to achieve a very steep attenuation curve between the two bands and an increased bandstop width.
