Abstract: ABSTRACT The invention comprises an electric igniter comprising a filament, a priming charge ignitable by heat generated in the filament by feeding an electric current therethrough, two connection legs for connecting the feed wires to the igniter and the filament and a high frequency filter to protect the igniter against accidental ignition by electromagnetic fields or static electricity.  The casing of the igniter comprises a wider part, the "cup", and a narrower part in which narrower part the connection legs are cast in a material which withstands pressure and high temperatures.  The igniter has a simple mechanical design by using capacitor and ferrite elements in the high frequency filter which elements are common for the two connection legs and by locating the ferrite element in the narrower part of the igniter.

Abstract: ABSTRACT           The primary crimp frequency of crimped material is optically measured by utilizing the pattern of light reflections produced by the waviness of the material.  The material is illuminated from one end thereof with light striking the material at a shallow angle to produce a pattern of bright and shadowed areas on the material.  The light pattern is scanned by a reticon camera and an amplitude modulated output signal corresponding to the light pattern is obtained.           The frequency of the output signal is measured to provide an indication of crimp frequency.

Abstract: Abstract of the Disclosure A precision roller chain with parallel runs and with an even number of links is trained around a sprocket wheel and an idler wheel and is driven around a racetrack-shaped path. To compensate for the inherent tendency of the chain to tighten and loosen in a cyclic manner, the idler wheel is formed with a smooth periphery and has a somewhat smaller diameter than the effective diameter of the sprocket wheel. In addition, compensating ramps hold the chain outwardly away from the idler wheel adjacent the tangency points of the idler wheel and keep the chain tight when the rollers of the chain are in angular positions which otherwise would cause the chain to inherently loosen.

Abstract: ABSTRACT     Process and apparatus for enhancing the erosive intensity of a high velocity liquid jet when the jet is impacted against a surface for cutting, cleaning, drilling or otherwise acting on the surface.  A preferred method comprises the steps of forming a high velocity liquid jet, oscillating the velocity of the jet at a preferred Strouhal number, and impinging the pulsed jet against a solid surface to be eroded.  Typically the liquid jet is pulsed by oscillating the velocity of the jet mechanically or by hydrodynamic and acoustic interactions.          The invention may be applied to enhance cavitation erosion in a cavitating liquid jet, or to modulate the velocity of a liquid jet exiting in a gas, causing it to form into discrete slugs, thereby producing an intermittent percussive effect.

Abstract: ABSTRACT OF THE DISCLOSURE          A method for the treatment of an effluent gaseous stream from a Kraft Recovery Boiler or the like.  The effluent stream passes through a venturi section where nucleation of the particulates is initiated and larger particles collected. Subsequently, the stream flows from the venturi section with the nucleated particulates and is scrubbed to remove the particulates, TRS and sulfur dioxide.  A portion of the bottoms from the packed section is recycled back to the venturi section at 15-25% dissolved solids by weight.  The total solids of the liquid stream in the venturi section is maintained at 1-5% above saturation.  Further concentration of a slipstream is achieved by cyclonic separation or filtration.  The pH in the venturi section is controlled to agglomerate the suspended solids.  The bottoms from the venturi section are subsequently concentrated externally to the venturi section to between 40-60% solids.

Abstract: ABSTRACT OF THE DISCLOSURE           A sub-Nyquist sampled PCM  NTSC color television signal is obtained directly from a PCM encoded color television signal sampled at four times the color sub-carrier frequency by selecting every other sample in each line of the 4Fsc sampled television signal and introduc-ing a one 4Fsc sample displacement every two sequential television lines.  A sub-Nyquist sampled signal may also be obtained from an NTSC color television signal having a color subcarrier frequency Fsc by generating a sampling signal having a frequency of 2Fsc, the sampling phase of which shifts by 180° every alternate/time sequented televison line, and sampling the NTSC color television signal in response to the sampling signal.  Whichever of these two techniques is used to obtain the sub-Nyquist samples, the 4Fsc samples can be reconstructed when comb filters are used to remove alias components.  The process of converting 4Fsc encoded signals to sub-Nyquist and back to 4Fsc can be repeated without impairing picture quality beyond that introduced during the first conversion - reconversion process.
