A floating vessel is moored to a floating facility, a fixed dock or another floating vessel by a pair of rigid compressive links pivotally connected to each other and to the two facilities that are to be moored to each other. A partly submerged spar buoy is pivotally connected to the two rigid links at their pivotal connection to each other and, by virtue of its weight and buoyancy, provides a restraining force acting through the rigid links that tends to maintain the distance between the two in...

A controllable dispenser which dispenses an aqueous solution of a soluble substance. The dispenser has an inlet to accept a supply of water and an outlet to discharge the solution. The dispenser includes a container having a chamber, where the soluble substance is placed, and a passage surrounding the chamber. The chamber is longitudinally in line with the inlet and outlet. The water entering the device is able to flow through both the chamber and the passage. The fluid flowing through the passa...

A voltage controlled oscillator (VCO) includes a voltage controlled load. The voltage controlled load supplies additional capacitive loading to the VCO, via a transmission gate, at low frequencies to decrease the frequency-gain factor of the VCO. Moreover, at high frequencies, the effect of the voltage controlled load is minimized by turning off the transmission gate thereby allowing the VCO to operate at maximum frequency for worst case speed conditions.

A controlled oscillator having an anti-resonant tank circuit tuned by an admixture of an adjustable portion of quadrature current responsive to oscillation signals appearing across the tank circuit. The adjustable portion of quadrature current is provided by adjustably splitting a fixed quadrature current into first and second fractions in a current splitter in response to a control signal, then subtracting the first fraction from the second to obtain a difference current which is applied to the...

A platform is mounted for movement in x and y directions and carries a stylus, vibrator and a cutting tool. An operator moves the stylus along a master pattern causing the cutter to cut the master pattern in a sheet of suitable material, such as, 1/16 inch magnesium, plastic or alluminumate.

A rectifier circuit, for alternating current, has a plurality of controlled rectifiers and a separate quenching device for each of the controlled rectifiers. Each quenching device is connected in parallel with its associated controlled rectifier and includes a quenching thyristor and a quenching capacitor connected in series. A supplemental capacitor is connected in parallel with each of the quenching capacitors. A coupling diode is in the path connecting the supplemental capacitor with the quen...

A clutch means 50 having an actuated condition for retarding relative rotatio...

Control apparatus for controlled rectifier battery chargers and battery eliminators includes a reference voltage source, error amplifiers for voltage and current control, apparatus comparing error voltage with a ramp voltage synchronized with the power line frequency, and apparatus triggered by the voltage comparator generating a train of gating pulses for silicon controlled rectifiers and the like.

An analog electrical signal-controlled pump having a reciprocating pumping element, pulse-operated means for reciprocating it at a rate proportional to the pulse rate of a pulse generator producing operating pulses at a predetermined rate from zero to a maximum and control means responsive to an analog electrical control signal, which establishes a predetermined pulse rate providing a rate of pump element reciprocation as a linear function of the control signal. The control means includes pump c...

A controlled deflection roll having a stationary shaft supported at its ends, a roll shell rotatably positioned on the shaft and fluid support means between the shaft and shell transmitting the force of a load on the shell to the shaft, the fluid support means having a lubricating fluid in engagement with the inner surface of the shell, and a heat exchanger supported on the shaft circulating the lubricating fluid and controlling its temperature to control the temperature of the shell with a heat...
