Patent CA-2112401-A1 (CA)
Inventor: HARFORD JACK R
IPC: H04N5/44
Filed: 1993-04-21
Abstract: A high-performance television receiver synchronously detects the picture IF  signal. A synchronous impulse noise in the IF signal generates either positive-going noise or negative-going noise in the video signal supplied from a synchronous video detector, which noise is subsequently replaced by a value of video signal occurring previous to the impulse noise in the following manner. The video signal contaminated with impulse noise is supplied as input signal both to an impulse noise detector and to a delay line. The output signal from the delay line, delayed by about 240 ns, is supplied as the signal for tracking by a track-and-hold circuit. The detected impulse noise signal is used to actuate the hold condition in the track-and-hold circuit. By stretching the pulse from the impulse noise detector for the 600-800 ns duration overlapping the duration of most impulse noise, the track-and-hold circuit replaces most impulse noise with previously stored values of the delayed video signal. This not only generally avoids the appearance of white impulse noise and ensuring black impulse noise in the televised picture, but avoids the application of impulse noise to the chroma channel receiving synchronously detected video signal as its input signal. Shock excitation of the chroma channel is accordingly avoided, so chroma "twinkle" does not appear in the televised picture.

Abstract: A diagnostic method of diagnosing a press for the presence of any abnormality that deteriorates a quality of a product manufactured by the press, wherein physical value (Fs, Fsi, Ff, Ffi, Fp, Fpi, Xsi, Xei, Xy, Xz, Vx, Gx, Gy, Gz, Temp A, Temp B, Va0, Vf0, Vd0, V, Aa, Ag, Az, Afi, Ps, Pmai, Psa, Paa, Pyai, Peai, Pzai) such as a load generated at a selected portion of the press during operation of the press is detected, and the press is diagnosed for any abnormality, on the basis of the detected physical value, and according to a predetermined reference. For example, the diagnosis is effected based on: a waveform of a load detected in relation to a physical value which changes during a pressing cycle; a distribution of local values of the load detected local portions of the press; a correlation between the load and the physical value; a patter of variation of the load as the number of pressing cycles; a displacement amount, velocity or acceleration, or a temperature of a selected component of the press; or a capacity of a fluid used for a cylinder which produces a load or force.

Title: Low NOx Combustion System for Fuel-Fired Heating Appliances
Inventor: LU LIN-TAO
IPC: F24H3/06
Filed: 1994-08-24
Abstract: A fuel-fired, forced air, draft induced heating furnace is provided with NOx reduction apparatus associated with a plurality of combustor tubes forming a portion of its heat exchanger structure.  In-shot type fuel burners are spaced apart from and face the open inlet ends of horizontal combustion sections of the combustor tubes.  The NOx reduction apparatus includes a plurality of metal mesh tubes having diameters substantially less than the internal diameters of the combustion tubes.  The mesh tubes are coaxially supported within the combustor tubes, adjacent their inlet ends, by elongated support members longitudinally passing through the mesh tubes and having first ends anchored to the combustor tube inlet ends, and second ends slidably resting on internal side surface portions of the combustor tubes.  During burner operation the burner flames injected into the combustor tubes are forced through the mesh tubes which operate to laterally reduce the cross-sections of the flames, increase their axial velocity through the combustor tubes, and substantially diminish the intimate contact of secondary combustion with the maximum temperature zones of the flames within the combustor tubes.

Patent CA-2120238-A1 (CA)
Title: A check valve
Inventor: HORNER CHARLES B JR
IPC: F16K15/06
Filed: 1992-10-09
Abstract: A check valve (10) for use in the evacuation of air from a system having primary and secondary disc (32, 34) retained in a chamber of the housing (12) and responsive to first and second forces developed by the creation of a fluid pressure differential between the fluid pressure of air in a first member and a source of vacuum to control the evacuation of air from the member by the source of vacuum. The primary disc is located on a stem (38) that extends from the secondary disc to cover a plurality of openings (42, 42') which connect the inlet port (16) to the chamber. A spring (52) holds the secondary disc against the housing. The first force which develops as a result of a pressure differential between the fluid pressure of air and vacuum moves the primary disc to allow air to be evacuated through the openings in the secondary disc.  Should the fluid pressure in the air located in the first member exceed a predetermined value, the second force develops which acts on the secondary disc to allow a larger volume of air to be evacuated in a shorter time. A tang (50) on the secondary disc engages the housing to prevent the development of vibrations therein when air is evacuated as a result or movement by the secondary disc. When the fluid pressure of the air is reduced to a predetermined fluid pressure, a spring moves the secondary disc into engagement with the housing and the evacuation of air is again through the openings in the secondary disc as controlled by the first disc.

Abstract: An implantable atrial defibrillator applies cardioverting electrical energy to the atria of a human heart in need of cardioversion after first determining if there is an absence of potential atrial fibrillation. A sensor associated with the atria of the heart senses activity of the heart and generates a cardiac signal and a first detector detects cardiac events from the cardiac signal. A second detector responsive to time spans between immediately successive detected cardiac events which are greater in duration that a preselected interval detects for an absence of potential atrial fibrillation. An atrial fibrillation detector detects for atrial fibrillation if the second detector fails to detect an absence of atrial fibrillation, and a cardiovertor applies cardioverting electrical energy to the atria when the atria are in fibrillation.

Abstract: A page wide piezoelectric ink jet print engine and a method of manufacturing the same.  The page wide ink jet print engine includes lower and upper body parts, each formed from piezoelectric material and having a plurality of  generally parallel, spaced projections.   Lower side surfaces of the projections of the lower body part are conductively mounted to corresponding bottom side surfaces of the projections of the upper body part to define a plurality of generally parallel, axially extending ink-carrying  channels  from  which  ink  may  be ejected.  The lower and upper body parts are then circumferentially poled such that, for the lower body part, first and second polarization fields respectively extend between the top side surface of each one of the projections and top side surfaces of first and second projections adjacent thereto and,  for the upper body part first and second polarization fields respectively extend between the bottom side surface of each one of the projections and bottom  side  surfaces  of first  and  second projections adjacent thereto.  By applying voltage to selective ones of the projections, the channels may be selectively expanded to draw ink from an associated ink delivery system and compressed to cause the ejection of a droplet of ink therefrom.
