The frequency of a reference oscillator is controlled by a reference voltage which is altered at the beginning of an output cycle to equal the instantaneous value of the averaged outputs of a first oscillator and a second oscillator. In a preferred embodiment, the outputs from the reference oscillator and the second oscillator are summed, and this voltage is used to control the power output to a load.

A random noise generator for providing useful random noise power without amplification includes an anode and cathode element, disposed within a glass housing, with the electrical breakdown occurring therebetween along the inner surface of the housing is capable of generating broad band white noise.

An MOS dynamic random-access memory (RAM) realizable as a 64K RAM is disclosed. Single transistor cells employing capacitive storage are coupled to folded bit-line halves. These bit-line halves are connected to sense amplifiers employing cross-coupled transistors. Boosting means employing a variable capacitance are coupled to the bit-line halves to boost the potential on a line during reading. The capacitor associated with each of the memory cells is coupled to a potential which is greater than ...

A control valve which can randomly select any one of a plurality of conduits for controlling the flow to a single output port. The valve is comprised of base plate and a cover or bearing plate, which together form a housing having a cavity. A slider or block of the same shape, but slightly smaller than the cavity, is confined in, but may move freely in the cavity to align a port in the base plate with ports in the slider. The slider has a plurality of ports and as the slider is moved from one co...

5. An intelligence communication system comprising a transmitter and a receiver; said transmitter comprising means for obtaining a relatively wide band random energy carrier signal, means for modulating said random carrier signal with an intelligence signal thereby forming a message signal, means responsive to said wide band energy obtaining means for deriving a reference signal which differs in frequency with said message signal by a definite fixed amount and means for radiating to the receiver...

Random number generators are provided in the form of one or more ten-sided dice, made up of two, identical, regular, five-sided pyramids with planar bases face to face. The faces of each die on opposite sides of the equatorial plane defined by the bases are offset 36.degree. from one another. The equatorial plane is perpendicular to a central axis extending through the apexes of the pyramids and bounded by a circle. The surface of the die immediately contiguous the equatorial plane is formed by ...

This invention relates to random linear copolyesters containing units of terephthalic acid, butane diol, polytetramethylene glycol and dimer acid. The copolymers are elastic materials and can be made into films, fibers and molded products.

A method and apparatus for randomly applying a foam composition containing a coloring agent dispersed therein onto a textile fabric is disclosed. The coloring agent is mixed into the foam in a non-homogeneous manner and randomly applied onto a fabric in a system having random application means for delivering the foam-coloring agent composition to a depositing means which is rotated and moved transverse to the direction of travel of the fabric being treated. The foam-coloring agent composition is...

Random motion mechanisms having at least one driving element that is operated at randomly varying speeds. One such mechanism is a self-propelled vehicle which has at least one randomly operated driving wheel. The vehicle desirably has a second randomly operated driving wheel, which is parallel with the first, and at least a third supporting element which can take the form of a wheel.

A memory cell comprising field-effect transistors for use in a random access memory array. The cell is of the dynamic type wherein data is stored on capacitive elements, and is self-refreshing; no circuitry external to the array is needed for refresh, other than clock sources. Four MOS field effect transistors are employed, with two non-overlapping clocks, a data buss for each row of the array and one address line for each column. One of the storage capacitances may be a voltage-dependent capaci...
