A flashing and sound generating lamp that repeats on-off operation and generates a characteristic audible sound when an electric current is supplied to the lamp. The lamp comprises a thermally bendable member connected in series or in parallel with the lamp filament to effect on-off energization of the filament as a result of the bending of the member due to the presence and absence of radiant heat from the filament, and a concavity is prefabricated into the thermally bendable member to cause th...

A flow passage having a restriction is connected between a fluid inlet and outlet. A bluff body such as a frustum or disc is disposed in the flow passage between the inlet and the restriction. The inlet is transverse to the axis of the flow passage. The bluff body is mounted on a rod extending through the flow passage. In one embodiment, a sphere is mounted on the end of the rod beyond the outlet. The rod may be hollow and have holes near the restriction for the purpose of liquid feed. As fluid ...

A continuous water flow from selected ones of a plurality of reservoirs passes through turbines or the like within an hydroelectric power station to produce electrical power. The reservoirs are cyclically filled and evacuated through the power station by operation of a plurality of gates interconnecting reservoirs having different water height levels and an adjacent source of tidal waters. By programmed operation of the gates a continuous water pressure head can be maintained at the power statio...

A generating plant is driven by a gas turbine, which is run with combustion gases from gas coming from a carbon pressure reactor and which obtains the combustion air necessary for its operation from a primary compressor driven by the gas turbine by means of a final compressor connected at the outlet side of the primary compressor. The final compressor is driven by an expansion turbine connected between the pressure reactor and the combustion chamber acting to produce the combustion gases. During...

In an electronic character generating apparatus a display cathode ray tube is subjected to deflection in accordance with a television type raster. Some of the signals from a conventional character generating device which are applied to the tube during fixed time durations of successive television line periods so as to produce a character-simulating pattern of rectangular dots, are modified as to their time durations so that the dots of the pattern are modified in shape so as to be non-rectangula...

Motion of waves is converted into energy in the form of compressed air which is stored in large containers. Compressed air flowing from the containers is utilized to drive turbine-generators to generate electricity. The turbine-generators are selectively driven by stored energy which may be controlled. Generation of electricity may be varied to meet the demand regardless of the tides or the state of the waves.

A system for automatically animating scenes viewed by a video camera and displaying the animated scenes. Animation can be collectively of the entire scene or separately of individual sections of the scene viewed by the video camera. Real time animation is selected from any of several pre-programmed animation sequences synchronized with the video camera.

Knockdown, prefabricated, steam generating apparatus includes a convection unit or boiler, one or more radiation units forming a furnace, and an unfired pressure vessel serving as a steam drum. The boiler includes upper and lower headers connected by front and rear banks of dog leg tubes forming a unit of rectangular section adapted for transportation with such section coinciding with the right of way cross section, the boiler height lying diagonally therein, and the width of the boiler extendin...

In a high voltage generating apparatus utilizing a piezoelectric transformer element driven by an AC voltage, the resonance frequency of the piezoelectric transducer element is varied by connecting a variable capacitor of small capacity between the output electrode of the piezoelectric transformer element and the ground.
