Abstract: A multifunctional mechanical display system comprises one or more signboards each having a substantially planar display area with a first bar member that preferably includes a plurality of posts which may be received in any of one or more parallel sets of openings through the signboard to position the first bar member at any of a plurality of parallel, spaced apart positions. Preferably, raised borders around the display area are parallel to the sets of openings and the first bar member and have, with the first bar member, facing sides which are adapted to receive and removably retain therebetween one or more planar, resiliently flexible inserts bearing preprinted indicia. Additional pins are further provided on the rear side of each signboard coinciding with one or more openings through the narrow sides of each signboard to permit the signboards to be joined together into larger signboards, to permit signboards to be mounted back-to-back, or both, through modular support members.

Abstract: An ultra-widebandwidth compressive receiver includes a power divider for processing a composite input signal consisting of individual input signals. The power divider provides a plurality of power divided signals to corresponding nondispersive delay lines. Each nondispersive delay line generates a unique time delay for each power divided composite signal. The unique time delay is generated in accordance with an arithmetic progression. The unique time delay has the effect of altering the phase of a corresponding individual input signal. The time delayed composite signals are provided to a frequency converter which heterodyne mixes them with local oscillator signals of frequencies which are a base frequency plus multiples of a reference signal frequency. The result is provided to a power combiner which re-combines the time delayed and frequency converted individual input signals in order to generate a group of narrow signal pulses that are separated in time according to their frequency.

Abstract: In accordance with practice of the process of this invention, a composition is provided which is useful as a dietary supplement. The composition, which comprises bile salts permanently complexed with insoluble cellulose, upon ingestion by a human, facilitates passage of fats through the gastrointestinal tract and out from the body.

Abstract: Flicker (1/f) noise is suppressed in an oscillator by reducing oscillator voltage-frequency pushing to zero. A varactor (56) is incorporated in the resonator circuit and is biased with a tuning voltage setting the varactor to a capacitance value providing the zero oscillator pushing at a given frequency. A common bias connection (62) is provided between the varactor and the active element (64) such that a random perturbation voltage change across the active element also causes a change in voltage across the varactor, to compensate a change in oscillator frequency otherwise caused thereby. The varactor capacitance versus voltage characteristic is shaped such that a change in active element voltage provides a change in varactor voltage, and the combination of these voltage changes results in a zero change in oscillator frequency. The tuning slope of the oscillator provided by the varactor is opposite the tuning slope of the oscillator resulting from a change in active element voltage.
