Abstract: In a home or business where there is a central sound source for a stereo and one or more sets of loudspeakers which are located remote as in different rooms from the sound source. A volume control switch is mounted in conjunction with each set of loudspeakers. Within the transmission line between the sound source and each set of loudspeakers there is included a sense signal which is located at a high frequency which is beyond the range of human hearing therefore not to be heard by any human. This sense signal is compared to the audio signal from which the position of the volume control for each set of loudspeakers can be ascertained. Upon initial activation of the sound source, sound is not emitted from the remote loudspeakers upon making a memory change in the volume control for a set of loudspeakers, sound will be immediately emitted from that set of loudspeakers and only that set.

Abstract: A radio antenna which takes the form of a flexible elongated transmission cable. This cable encloses a pair of conductors which are insulated from each other. The cable is encased in an electrically conductive sheath. The received signal is picked up by the sheath and transmitted through an impedance matching network and into the pair of conductors. The length of the sheath is correlated to a preselected fractional value of the wavelength of the received signal.

Abstract: A multi-channel sound simulation system for processing a stereophonic signal having a high frequency component for use with at least a pair of primary loudspeakers and a pair of secondary loudspeakers includes a receiving member for receiving the stereophonic signal and for producing a first primary channel signal and a second primary channel signal. The first and second primary channel signals are adapted to be respectively applied to a first primary loudspeaker and a second primary loudspeaker. The receiving member is further adapted to divide the input signal into a first secondary channel signal and a second secondary channel signal. The first and second secondary channel signals are fed through a roll-off member which inhibits the high frequency component of the signal, thereby producing inhibited first and second secondary channel signals.

Abstract: A radon gas detector which utilizes a light-tight housing which is formed into an interior environment connecting chamber and an interior radiation ascertaining chamber. Ambient air is continuously drawn through the environment connecting chamber and any radiation in the air produces scintillations which are picked up and magnified and concentrated onto counting and integration electronics which in turn causes activation of display electronics to give a display representative of the level of radiation that has been detected.

Abstract: An armrest to suspendingly engage within the window opening of an automobile door or other similar type of vehicular window. The armrest is to be adjustable to any desired position within the window opening. The armrest includes a fixed cushioning pad and a movably adjustable cushioning pad.

Abstract: An antenna which utilizes a conductive loop shaped element and a conductive tap element. The tap element is located directly adjacent the loop element and is precisely tapped to the loop element at one-half the length of the loop element. Connecting between the output terminal of the antenna and terminals of the loop element and the tap element are a plurality of tuning capacitors. The resulting antenna is small in size and is sensitive to a wide band of frequencies with respect to the center frequency of the antenna.

Abstract: A traffic reporting system which is to be in the form of a service that is to be subscribed to by each individual. Each individual is to have a receiver and this receiver is to be located within the individual's vehicle. This receiver is to have a plurality of activatable buttons with each button to correspond to a particular zone of a specific overall geographical area. If the individual presses a button, a continuous message will be announced informing that individual of pertinent information on traffic conditions relating to that specific zone. Each message for each zone is automatically frequently updated.

Abstract: The invention provides a method and apparatus for rapid and accurate stylus overhang positioning and tangential alignment with respect to a turntable. Accordingly a stylus locater plate having an aperture and a stylus positioning mark spaced therefrom is mounted on the spindle of a turntable. A pivot arm is connected to the locater plate on the other side of said spindle from the stylus positioning mark. The pivot arm and thus the locater plate, are then rotated around the spindle until such arm crosses over the pivot axis of the stylus arm of the turntable, to locate the mark in the turntable. The stylus arm is then pivoted toward the mark and the stylus cartridge is adjusted in the stylus arm to position the stylus in registration with such mark.The locater plate is further provided with lines near such mark to guide the angular positioning of the stylus cartridge into a tangential alignment with the record grooves at such mark.
