Abstract: An engine or pump is described which has a round cylinder in cross section, the surface of the cylinder being a round toroidal tube in the rotary direction. The cylinder is made of two equal parts, one part fixed and one part rotating with each part meeting on a flat surface at a right angle to the driveshaft. Force exerted axially against the rotating cylinder part by a spring diaphram seals the cylinder where the two parts meet on the flat surface. The spring diaphram is pre-loaded by a thrust bearing in a pre-loading disk to apply force to the rotating part of the cylinder. Within the cylinder are one or more round toroidal section pistons that are attached to the rotating part of the cylinder by piston pins. A hinged internal cylinder abutment is actuated by the piston as the piston passes through the abutment section. Working fluid to the cylinder is controlled by an internal valve actuated by a cam-disk on the driveshaft.

Abstract: A bag to aid in casting a bait fish is described. The bag is a throw-away or bag that is only used once because the bag is designed to disintegrate or come apart once it is in the water. The principal example is a bag that is long and narrow, being designed to hold a bait fish. Only the top of the bag is open for insertion of the bait. The sides, front, back, and bottom of the bag are closed and are glued together at the seams by a glue which very easily dissolves in water. Near the top of the bag on each side are two grommets. An attachment hook goes through the grommets and connects to a fishing line. The bag material is thin sheets which easily transmit water.

Abstract: A telephone system is described that includes a long line with a plurality of electrical conducting wires from a central office to at least one repeater and to at least one substation. Carrier frequency alternating signals are sent over a balanced pair of wires in the plurality between a first terminal at the central office and a second terminal at the substation. The repeater repeats and amplifies the carrier frequencies. A D.C. power source and/or an audio frequency source at the central office is connected to the plurality via a first line balancing network. The substation receives D.C. current and/or audio frequency current from the plurality via a second line balancing network. The repeater has a third and fourth line balancing network for receiving and bypassing D.C. current and/or audio frequency current in the plurality. The return path for the D.C. source and/or audio frequency source is an electrical conducting return medium which does not use the pair of wires.

Abstract: A boiler type of steam engine is described which uses a conventional boiler with an external combustion chamber which heats water in a pressure chamber to produce steam. A mixing chamber is used to mix the steam from the boiler with recovered recompressed steam. Steam from the mixing chamber actuates a piston in a cylinder, thereafter the steam going to a reservoir in a heat exchanger where recovered steam is held and heated by exhaust gases from the combustion chamber. Recovered steam is then recompressed while being held saturated by a spray of water. Recovered steam from a steam accumulator is then used again in the mixing chamber. Thus, the steam is prevented from condensing and is recovered to be used again. The heat of the recovered steam is saved by this process.

Abstract: A solar heater that heats air is described. The solar heater has a shape like a dome with a transparent outer cover and transparent inner cover. A dead air layer is inbetween covers. Inside the dome is a collector that holds up the covers and converts the solar rays to heat. Air or gas is circulated through the solar heater from an input pipe on one side to an output pipe on the other side, obtaining heat from the collector and base by conduction and radiation.

Abstract: This hybrid circuit utilizes two amplifiers such as operational amplifiers without transformers. A bridge arrangement is used in which there are four impedances, the line being one impedance. One amplifier is the second amplifier which is connected across two points of the bridge as a differential amplifier. The other amplifier is the first amplifier which is connected across the other two points of the bridge. One wire of the line acts as a common point for the bridge and the amplifier system. The bridge is a balanced configuration.

Abstract: A telephone system is described that includes a long line from a central office to a substation with amplifiers. At the substation a transformer hybrid is used to obtain isolation as well as a high trans-hybrid loss. A precision network balances the hybrid and terminates the long line. Regular telephone receiver and transmitter are used. Amplifiers are operational amplifiers that receive power from the long line. Various means of extending long lines are described using this substation, such as using earth ground.

Abstract: This steam engine uses an external combustion chamber where fuel is burned in the presence of air, both under pressure. Steam is forced into the combustion chamber at a medium pressure, thereafter being heated by combustion. Steam from the combustion chamber is released to do work in the engine, the pressure falling. Exhaust steam heat is recovered in a heat exchanger by condensed water which is turned back to steam. This new steam is compressed, after which the steam is injected into the combustion chamber to be heated.

Abstract: This solid state line circuit employs transistors, diodes, optical couplers, triacs, and other solid state components but no relays. It is designed to replace line cards in key telephone systems. This design utilizes semiconductors that are the "state of the art" such as optical couplers, SCRs and Triacs to replace relays. The circuit achieves the isolation and breakdown voltages required where other designs have failed.
