Title: Gas furnace switch
Inventor: LEE LUNG-HSIUNG
IPC: F24C3/12
Filed: 1988-08-02
Abstract: A gas furnace switch includes a switch base plate (1) with an ignition trigger member (11), and a spring-biased rotating shaft (2) extending through the baseplate (1) and having an ignition finger (211) and a restriction finger (212). Normally, the restriction finger (212) is confined within an area between the blunt inner edges of two limiting elements (41 and 42) which have tapered outer edges so that the rotary knob cannot be rotated. When the rotary knob and hence the rotating shaft (2) are in a depressed position, a gas on-off valve is opened and the ignition finger (211) abuts against the baseplate (1) allowing the ignition finger (211) to be rotated to activate the ignition trigger member (11) so as to achieve the ignition. The release of the thrust to the rotary knob allows the restriction finger (212) to be biased by the spring action so as to rest on a housing (3) outside of the area. At this time, the restriction finger (212) may be rotated clockwise or counterclockwise outside of the area to adjust the magnitude of the fire until it enters the area where the rotary knob cannot be rotated. <IMAGE>

Title: Encoding auxiliary signals with colour television signals
Inventor: STROLLE CHRISTOPHER HUGH
IPC: H04N9/835
Filed: 1991-04-24
Abstract: Apparatus and a method are disclosed for encoding, transmitting and decoding one or two auxiliary or control signals on a phase alternating carrier. The phase alternating carrier PAC is generated such that, in a given frame, it is in-phase on one scan line and out of phase on the next scan line relative to the conventional chroma carrier. The (I and Q) chroma information is modulated on the chroma carrier C in a conventional form to generate a chroma signal. The phase alternating carrier is modulated with one or two auxiliary signals from sources 32, 38 in a similar fashion. The encoded phase alternating carrier is then added to the modulated chroma carrier (chroma signal) and processed in the chroma channel for recording on a magnetic tape. A decoder or playback apparatus processes the chroma channel to decode the two modulated carriers. The modulated chroma carrier (chroma signal) is decoded in a conventional demodulator to recover the chroma (I and Q) information. The encoded phase alternating carrier is decoded to recover the original auxiliary signal. The auxiliary signals may be digital audio signals or motion signals indicative of motion in the scenes. <IMAGE>
