Abstract: A battery charging circuit uses a simplified design for converting AC to DC and powering a flyback transformer.      The switch of the flyback transformer operates at a high frequency and the time of the transformer is controlled to achieve a high power factor. The flyback transformer is fed a rectified AC signal which has not been smoothed in the traditional manner using a bulk hold capacitor and in rush limiting resister. Any treating to smooth the charging current for the battery is carried out on the secondary side. In many cases, no smoothing of the charging current is necessary. The time on of the switch is changed if necessary, slowly, relative to the pulsating input signals powering the primary winding. With a fixed T on, or slowly varying T on, dramatic fluctuations in the charging current are avoided.

Abstract: A low pollution engine (500) is provided for delivering power for vehicles. The engine has an air inlet (510) which collects air from a surrounding environment. A portion of the nitrogen in the air is removed using a technique such as liquefaction, pressure swing adsorption or membrane based air separation. The remaining air is primarily oxygen, which is then compressed and routed to a combustion chamber. The chamber has an igniter and inputs for the pressurized oxygen an d pressurized hydrogen containing fuel, including methane. The combustion products of water and carbon dioxide are expanded through a power generating device, such as a turbine or piston expander (560). The combustion products are then passed through a condenser (580) whe re the steam is condensed and the carbon dioxide is collected or discharged. A portion of the water is then routed back to the gas generator.

Abstract: A fishing lure for allowing selective deployment of a fish hook. The fish hook is pivotally mounted to the body of the lure. The hook is allowed to pivot between a retracted configuration wherein it is substantially housed within a hook recess formed in the body and an extended configuration wherein the hook bight end extends out of the body. An actuating mechanism located within the body allows the hook to be deployed upon tension being applied to the fishing line. A  biasing mechanism also located within the lure body biases the hook towards its retracted configuration. An adjustment mechanism allows for adjustment of the strength of the biasing force. The adjustment mechanism thus allows the biasing force to be customized depending on fishing parameters.

Title: Method and apparatus for regulating heater cycles to improve fuel efficiency
Inventor: HAMMER JACK
IPC: F23N1/08
Filed: 1998-03-20
Granted: 2007-06-12
Abstract: A method and apparatus for improving heating system efficiency. An electroni c circuit senses a firing signal from a boiler energy value sensor (26) such as a thermostat or pressuretrol. The circuit prevents the boiler energy value sensor from firing the burner, while the circuit senses an energy value of the outflow line (20) at the boiler (6). T he circuit monitors the outflow energy value and records the outflow energy value at a first time of the firing signal. The circuit then continually monitors the outflow energy until it detects an energy drop from the initial outflow energy value. The circuit responds to the energy drop by firing the burner (10). The invention self-adaptively responds to present thermal load, reduces the number of on-off cycles, increases each burner run time while reducing total run time, improves fuel consumption, and reduces air pollution.
