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 ...

A new class of compounds: R--W--R' were R and R' are identical oxy radicals containing peroxide functions such as dialkyl or diaralkyl peroxide, peroxyketal, peroxyester, or monoperoxycarbonate, and W is a carbonyl group, or carbonyl containing group, or an alkylidene or aralkylidene group, or a phosphorus containing group. Examples Di[1,3-dimethyl-3-(t-butylperoxy)butyl]carbonate; Di[1,3-dimethyl-3-(n-butoxycarbonylperoxy)butyl]carbonate; 2,2-Bis[3,3-di(t-butylperoxy)butoxy]propane; Di[1,3-dime...

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...

The disclosure relates to a charge coupled device (CCD) reader capable of reading and buffer storing the data stored in a punched card. This is accomplished by providing a charge coupled imager which may be of standard design with frames arranged in a rectangular array to coincide with the regions in the card in which holes are capable of being punched. The total size of the frames on the charge coupled device imager can be made large enough relative to the focused image of the punched card so t...

A charge coupled distributed amplifier comprises a first plurality of charge storage wells arranged along a first selected line, a second plurality of charge storage wells arranged along a second selected line, and a multiplicity of amplifier means, each amplifier means electrically coupling one charge storage well in the first plurality of wells to a corresponding charge storage well in the second plurality of wells. Charges are driven along the first and second pluralities of charge storage we...
