Title: Index signal amplifier for use in a beam  index television receiver
Inventor: ISONO KATSUO
IPC: H04N9/24

Granted: 1982-08-24
Abstract: INDEX SIGNAL AMPLIFIER FOR USE IN A     BEAM INDEX TELEVISION RECEIVER    ABSTRACT OF THE DISCLOSURE            An index signal amplifier arrangement is disclosed for use in a beam index color television receiver of a type which includes a picture reproducer having index stripes disposed to be scanned by an electron beam and a photodetector for detecting when respective index stripes are scanned by the beam to produce an index signal.  A local oscillator generates a local oscillating signal which is mixed with the index signal produced by the photodetector.  The mixed signal is amplified by a band-pass amplifier, the latter preferably being formed of a band-pass filter having a predetermined, limited pass-band characteristic substantially centered on the expected frequency of the mixed signal, and a limiter amplifier coupled to the band-pass filter for removing amplitude modulations from the filtered mixed signal.  Another mixer is coupled to the band-pass amplifier and also to the local oscillator for mixing the amplified mixed signal with the local oscillating signal to produce an amplified index signal having the index frequency.  If the local oscillating signal frequency can be adjusted to "match" the particular picture reproducer which is used in the color television receiver, then the frequency of the mixed local oscillating and index signals will be constant from one picture reproducer to the next.  Consequently, a standard-ized, or uniform band-pass amplifier may be provided for all picture reproducers.                                  -i-

Abstract: AN AIR DISTRIBUTION SYSTEM               Abstract of the Invention This invention relates to an air distribution system for a vehicle cab.  The system uses two blowers: a first constant-volume blower for drawing fresh outside air into the cab and a second variable-speed blower for recirculating the inside air.          An air filter is positioned upstream of both blowers for filtering out dust and other contaminants.  As the fresh outside air passes through the first blower, it is mixed in a mixing zone with inside air which passes through the second blower.  This inter-mixed air is then passed through a temperature controller which includes a heating unit and an air conditioning unit.  The temper-ature controller treats the air stream before it is routed through a series of ductwork to various parts of the operator's compartment of the cab.  This two-blower air distribution system is a vast improvement over conventional air distribution systems in that it always provides for a positive air pressurization within the cab thereby preventing the influx of dust.

Abstract: Abstract Floatable tube sheets are provided for use in a reformer furnace or the like wherein a plurality of vertically oriented catalyst tubes are dis-posed in the fire box with the upper tube ends extending through the fire box roof.  The tube sheets are located proximate apertures or channels in the roof through which the upper tube ends protrude and provide a seal to substantially minimize air leakage through the roof.  At the same time, the tube sheet plates permit vertical expansion and contraction of the tubes.  The tube sheet plates themselves are moveably mounted to the roof so that they can float vertically upwardly and downwardly through a limited distance so as to compensate for tube movement in those instances in which the tubes become bent or bowed during oper-ation.  At least a pair of contiguous tube sheet plates surround each tube to facilitate easy tube sheet removal without resulting in attendant removal of any neighboring tubes or, in some instances, furance shutoff.
