Abstract: A system for providing recorded audio programming in digital form, comprising a computer server capable of digitally recording, holding and uploading audio programming in either musical or voice formats and able to transmit such modulated digital data in a time-compressed, encrypted and encoded manner through a wireless transmission, where the data is received using RF electronics, then stored for transfer to a combination audio receiver/player/data storage device. This storage device comprises a readable/writable memory storage mechanism (e.g., disk drive, hard drive, memory or flash card system) and playback or player feature interfaced with a mobile or fixed site RF receiver capable of receiving wireless transmissions. As the transmissions are received, the programming data is demodulated and stored in digital form and then converted to “real time” audio one file at a time, utilizing a digital-to-analog converter, and played back to the listener.

Abstract: A vertical coil for a television deflection yoke comprises a plurality of winding emplacements or layers wound in a shootback manner. The abrupt change in wire direction following the shootback winding tends to cause displacement of the initial turns of the subsequent winding emplacements. In order to prevent this displacement, the coil winding emplacements are wound with progressively greater winding angles so that the initial turn of each subsequent emplacement lies along the core surface and abuts the previous winding emplacements. The presence of the previous emplacements obstructs and prevents movement of the initial wire turns of each winding emplacement which allows the coil to be wound without the need for winding shootback straps or core end rings.

Abstract: A frequency converter for use with a generator, particularly a gasoline engine driven generator, to provide electrical power at a suitable frequency through a power switching circuit with a timing control circuit to protect the power switching circuit.
