Patent CA-1319189-C (CA)
Inventor: MARTIN THOMAS F
IPC: H04N7/16
Filed: 1987-10-30
Granted: 1993-06-15
Abstract: ABSTRACT     A cable television channel selector/descrambler enables the full capabilities of a cable-ready video appliance (e.g., television set or VCR) to be used in conjuncton with a cable television system providing unscrambled channels and scrambled premium channels. A broadband cable signal containing a plurality of television signal channels having different frequencies is passed through a filter to produce a modified cable signal having one of the signal channels removed therefrom.  The broadband cable signal is input to a tuner for selectively tuning only to scrambled signal channels contained in the broadband cable signal.  The tuner is tuned to a scrambled signal channel to be viewed by stepping through the scrambled signal channels accessible by the tuner until the desired signal channel is reached. A scrambled signal tuned by the tuner is descrambled and remodulated to convert it to the frequency of the signal channel removed by the filter in producing the modified cable signal.  The re-modulated descrambled signal is combined with the modified cable signal to form a composite signal for input to a video appliance.  The composite signal contains all of the original unscrambled channels together with the selected premium channel which has been descrambled.

Title: Compact hydrogen generator
Inventor: SZYDLOWSKI DONALD F
IPC: H01M8/06
Filed: 1988-01-20
Granted: 1992-07-07
Abstract: Abstract Compact Hydrogen Generator The device catalytically reforms a raw hydrocarbon fuel to a hydrogen rich gas for fueling a fuel cell stack.  The device is compact so as to be usable in mobile or temporary applications such as in vehicles, trailors, as an emergency generator or the like.  The device has generally cylindrical housing with an axial burner and a helical catalyst tube outside of the burner and inside of the housing.  A refractory heat shield sleeve is interposed between the burner and the helical tube so that heat from the burner progresses to one end of the housing and then passes between the heat shield and housing side wall to envelop the catalyst tube.  A gas deflector and swirler may be disposed at the end of the heat shield to properly direct the hot gases from the burner to the catalyst tube.  Raw fuel is percolated through the catalyst tube and converted therein to a hydrogen rich gaseous fuel.

Abstract: Polymer bound stabilizer compounds are provided in which two or more different classes of stabilizers are chemically bound to anhydride containing polymers or copolymers.  The polymeric stabilizers are prepared by the reaction of primary amino or hydrazido substituted stabilizers (i.e., antioxidants, light stabilizers, etc.) with some or all of the anhydride groups of the polymer or copolymer to form pendant stabilizer substituted imide or amic acid groups. The polymer bound stabilizers are not lost from the polymer system by volatilization, migration or extraction, even at high temperatures.  The polymer bound stabilizer compounds may be used as concentrates to stabilize other polymer systems.

Filed: 1988-07-05
Granted: 1993-05-18
Abstract: Abstract of the Disclosure A method is disclosed of making an on-line gas analysis of a multicomponent gas emission flow by (a) continuously sequestering a sample flow from the gas emission flow, which sample flow has been filtered to substantially eliminate solid or liquid particles, diluted to lower its dew point to below room temperature, and changed in either temperature and/or pressure to be substantially the same in temperature and pressure as that of gases used to create reference transmission frequency spectral data deployed in step (d); (b) continuously irradiating the sample flow with an electromagnetic radiation beam while modulating the amplitude of infrared frequencies in the audio frequency range of the beam, either prior to or immediately subsequent to irradiation of the sample flow, to produce electromagnetic signals having discernible amplitude variations resulting from spectral interference patterns; (c) detecting and collecting the signals at a sufficiently high rate to substantially completely distinguish between adjacent spectral pattern amplitude peaks without mutual spectral interference and to permit analysis of the signals in real time: and (d) analyzing the signals in real time by (i) mathematically manipulating the signals in accordance with Beer's Law to create reformed background-corrected data, and (ii) applying reference transmission frequency spectral data to the reformed data for each suspected gaseous component to give a linear quantitative measure of the presence of each and every suspected gas component in the gas emission flow.

Title: Digital video compression system
Inventor: GOLIN STUART J
IPC: H04N7/24
Filed: 1988-10-04
Granted: 1994-11-15
Abstract: A full motion color digital video signal is compressed, formatted for transmission, recorded on compact disc media and decoded at conventional video frame rates. During compression, regions of a frame are individually analyzed to select optimum fill coding methods specific to each region.  Region decoding time estimates are made to optimize compression thresholds.  Region descriptive codes conveying the size and locations of the regions are grouped together in a first segment of a data stream.  Region fill codes conveying pixel amplitude indications for the regions are grouped together according to fill code type and placed in other segments of the data stream.  The data stream segments are individually variable length coded according to their respective statistical distributions and formatted to form data frames.  The number of bytes per frame is dithered by the addition of auxiliary data determined by a reverse frame sequence analysis to provide an average number selected to minimize pauses of the compact disc during playback thereby avoiding unpredictable seek mode latency periods characteristic of compact discs.  A decoder includes a variable length decoder responsive to statistical information in the code stream for separately variable length decoding individual segments of the data stream.  Region location data is derived from region descriptive data and applied with region fill codes to a plurality of region specific decoders selected by detection of the fill code type (e.g., relative, absolute, dyad and DPCM) and decoded region pixels are stored in a bit map for subsequent display.

Abstract: Invention:  CONTROL APPARATUS FOR REFRIGERATED CARGO CONTAINER Inventor:   MICHAEL J. BRANDEMUEHL and JOHN R. REASON          Abstract of the invention A method of closely controlling the supply air temperature delivered from an air conditioning unit into a mobile cargo container wherein the supply air temperature is compared to a desired set point temperature and a suction control valve in the air conditioner compressor,inlet line is adjusted in response to the sensed difference between the supply air temperature and the set point temperature.  Three different preprogramed control modes are available which are selected automatically in response to the amount of deviation between the compared temperatures that are used to bring the supply temperature down to the set point temperature and hold it under steady state conditions within ?0.25°C of the set point.  A trim heater is placed in the supply air passage to warm the supply air any time the control valve is in a full closed position.  This increases the heating load on the unit so that operating time of the unit will be prolonged and the compressor will not be cycling ON and OFF.
