A power supply system includes a plurality of batteries or banks of batteries for supplying direct current to a load, a plurality of switching devices each coupling a different one of the batteries to the load and each responsive to an energizing signal for conducting current from the respective battery to the load, and control apparatus for successively energizing each of the switching devices one at a time so that each battery provides current to the load only for a short period of time after ...

A negative energy power supply which operates submerged equipment like a hydraulic actuator. A main component of the system is a submerged chamber held at substantially atmospheric pressure. It is connected to submerged equipment having intake and discharge ports controllable by remotely operated valves. When the intake port is opened to water at the submerged depth of the equipment and the discharge port is vented to the chamber, the resulting pressure difference operates the submerged equipmen...

An ink package comprising a disposable container is provided for supplying ink to an ink fountain of a lithographic duplicating machine and includes a self-contained, sealed package provided with specially configured nozzle means for dispensing ink from the container directly into an ink fountain. The ink used in the container is designed to be within the higher ranges of flowability for lithographic ink, and hence, due to special design of the nozzle aperture or apertures, is able to flow slugg...

An inexpensive portable liquid supply tank that serves initially as a shipping container and as a solute or solution dispenser and pump unit carried on a person's back by shoulder straps whose upper support effort is transmitted to the tank about a center of gravity designed to be close to the carrier's back on a strain line directed through its volumetric center of gravity as determined by interbraced semi-flexible front and back walls for carrying comfort and with the straps and a liquid educt...

A municipal water supply system for providing potable water under pressure from sea water including a nuclear reactor heated boiler for raising the temperature of sea water to at least 250.degree. F and at superatmospheric pressure means for conveying the superheated steam to an expansion turbine, whereby the superheated steam drives the turbine while the temperature of the steam is reduced to about the boiling point of water at atmospheric pressure, a heat exchanger for condensing the exhaust f...

A power supply provides a low-level DC voltage to DC load circuits by first rectifying the standard AC voltage and thereafter reducing the rectified AC voltage to the low-level DC voltage. The reduction of the rectified AC voltage to the low-level DC voltage is accomplished by a power transformer which is switched on or off by a pair of switching transistors. The switching transistors are operated in a "push-pull" mode by a pair of control transformers operating in combination with a control cir...

A laser power supply includes a dc to dc converter which feeds a multiplier-rectifier circuit to provide a high dc voltage output. The converter includes a power transistor which is subject to a control of its on time to provide constant current regulation. A smooth regulation is provided by a proper timing of the turn off signal to the power transistor by sampling the emitter signal of a transistor which is included in a synthesized thyristor, the thyristor being operable to hog base current fr...
