Title: Parametric loudspeaker with electro-acoustical diaphragm transducer
Inventor: CROFT JAMES J III
IPC: H04R19/00
Filed: 1999-08-26
Abstract: A parametric loudspeaker that directly generates multiple high frequencies t o indirectly create lower frequencies through the use of substantially monolithic film transducers that are generally larger than a wavelength of t he carrier frequency in diameter or cross section. These film transducers (33) include electrostatic, electret, PVDF, electrothermal mechanical film, and planar magnetic configurations. Metal, foam, plastic or wood support structures or stators (31) may be used to support the film transducers. An alternative configuration may include a movable diaphragm stretched along th e core member and displaced a short distance within a strong portion of a magnetic field. At least one, low mass, planar, conductive coil is disposed on the movable diaphragm and includes two contacts for enabling current flow through the coil to produce a first magnetic field to attract and repel the diaphragm at a desired frequency for development of a series of compression waves which may be adjusted to include an ultrasonic frequency range.</SDOAB >

Patent CA-2372732-A1 (CA)
Inventor: PERRICHON CLAUDE ANNIE
IPC: H04R1/24
Filed: 2000-05-22
Abstract: Knowledge of membrane transducers do not provide the entire musical quality. The speed of movement is too slow owing to the inertia of the coil membrane mass. The method uses a constant electromagnetic field as reference and at least a variable electromagnetic field, compelling the air particles to be activated to the rhythm of an audio modulation. An apparatus consisting of at least a primary winding electrically connected in series or in parallel to an electrical circuit for audio powering a loudspeaker, generates a depolarisation of the air particles. Said apparatus is a fixed motor with revolving field and also a transformer, by its being an inductance, thereby enabling to eliminate blast filter components, completely or partly. The apparatus and the method constitute an acoustic complement for sound reproduction, in all audio and audio-visual fields.

Inventor: TEPSA BRIAN
IPC: F16K17/26
Filed: 2002-05-08
Abstract: A gas safety valve is provided which has a valve chamber within a housing, and a gas inlet and outlet respectively communicating with an inlet and outlet end of the valve chamber. A valve is disposed in the valve chamber for allowing gas to flow from the inlet to the outlet when the valve is in an open position, and preventing gas flow when the valve is in a closed position at either end of the valve chamber. The valve may include a piston having a tortuous gas transmitting opening therein, the resistance to gas flow caused by the tortuous opening rendering the valve responsive to slight variations in gas pressure differential between the inlet and the outlet. A resilient spring is provided which extends between the outlet and the valve. The spring urges the valve into the open position, and allows it to reversibly move to a closed position against the outlet when the pressure differential between the inlet and outlet of the valve chamber becomes sufficiently high to overcome the resistance of the spring.
