Abstract: A method and apparatus using atmospheric pressure and vacuum force to generate electricity performs coordinated operations of normally open (NO) valves and normally closed (NC) valves to repeatedly push water through an upward pipeline to a first vacuum chamber and let the water flow down by gravity to strike the water wheel of a hydraulic power generator installed in a second vacuum chamber to generate electricity. Specifically, two NC solenoid valves are included to regulate the water flow inside the apparatus, whereas a third NC solenoid valve is included to enable or disable the atmosphere's interaction with the air pressure cylinder of the apparatus in regulating the water flow in each power generation cycle. The method and the apparatus is not affected by local climates or geographical locations and may be installed and applied almost anywhere.

Abstract: A method and apparatus utilizing atmospheric pressure and vacuum force to generate electricity by pushing water in a water tank through an upward pipeline to a first vacuum tank and letting the water flow down to strike against the vanes of a hydraulic power generator installed in a second vacuum tank to generate electricity. Intermediate vacuum tanks may be added between the water tank and the first vacuum tank to raise the altitude of the first vacuum tank to increase the impact of the down-flowing water. The method and the device used is not affected by local climate. The device can be installed in the backyard of a house or in a factory, operating around the clock in all seasons. The apparatus may be used to deliver water to a high altitude for water distribution.

Abstract: A condom comprising a flexible tubular sheath and a length of adhesive tape fixedly provided with granules on the non-adhesive side is disclosed. In use, the length of adhesive tape is wrapped around and adhered to an erectile penis before the flexible tubular sheath is worn over the penis and the granules. The granules, the hardness of which being modulated by the flexible tubular sheath, will stimulate and enhance sensuality during sexual intercourse.

Abstract: A method of generating power is disclosed wherein a liquid having a boiling point near the ambient temperature when it is under atmospheric or moderately higher pressures, preferably propane, isobutane, Freons or ammonia, is placed in a pressure vessel, heat energy is gathered from a naturally occurring heat sources, such as by solar collectors or from hot springs, geothermal or other heat sources, and transmitted through conduction heat pipes to the liquid in the pressure vessel, and the liquid is thereby heated to the boiling point and vaporized. When a liquid is vaporized, its volume expands by several hundred times, creating a pressure sufficient for driving motors. This invention can be used in automobiles, motorcycles, generators, ships, homes, factories, and other suitable places to drive motors, thus reducing the use of petrochemical fuels.

Abstract: A signal device for use in fishing includes an adjustable contact member and a slidable contact member which can be moved into contact with each other by a fish when striking the bait to cause energization of a relay means for controlling the operation of a buzzer and lamp system. A normally closed reset switch is provided for maintaining the energization of the relay means in case the two contact members are out of contact with each other so that signals from the buzzer and lamp system are continuously produced to positively warn of a hooked fish.
