Abstract: ABSTRACT      A machine for packaging objects such as rolls of paper comprises a direction changing loading wheel to feed objects and groups of objects into closely grouped orientation in the wrapping machine for high speed passage through the machine in a continuous motion generally in a single direction and substan-tially at a single speed.  A wrapper supply mechanism feeds sheets of wrapping material to lie between conveying belts above the article to be wrapped with the leading edge of the wrapper substantially ahead of the article or group of articles to be wrapped.  A pair of vacuum wheels alongside the path of the ar-ticle on axes skewed slightly outwardly from the article path pull the wrapper down in front of the article and allow it to pass underneath as the article passes so that the wrapper becomes wrapped around the top, front and bottom of the articles. Specialized belts and rollers below the periphery of the vacuum wheels assist in smooth transfer of the wrapper without permitting wrinkles at that very high speed.  The articles are then transferred from the belt conveyor to bars above and below the article, with chain driven paddles to propel the articles and to wrap the upper and lower portions of the tail of the wrapper about the rear of the articles while at the same time differences in the coefficient of fric-tion between the upper and lower bars snug the wrapper about the article and close any spaces between articles in a group.  The ends of the wrapper are folded in and the ends and rear seam are sealed to continuously produce wrapped product groups as the groups move in a linear path, in part by a novel fold tucker.

Abstract: VALVE ASSEMBLY FOR SHOCK ABSORBER     Abstract of the Disclosure:    A valve assembly for use with and for reducing the noise in a shock absorber provided with a valve chamber containing a valve cooperating with a valve seat.  The valve is held in a preferred position by pretensioning means such as a spring.  One or more supply channels lead to the valve seat side of the valve.  The valve assembly is provided with a screen offset in the opening direction of the valve in relation to the valve.  The screen is of sufficient rigidity to protect the valve against pressure waves of the damping medium in the closing direction of the valve.  Accordingly, the direction of the pressure shock in the valve chamber, with respect to the movement of the valve, is opposite to the closing direction of the valve.  Thus, the production of valve noise is prevented and the life of the valve and the valve seat is extended.     1a

Abstract: ABSTRACT OF THE DISCLOSURE           Pulverulent solids, such as hot spent shale residue from the production of shale oil by the pyrolysis of oil shale, are economically and efficently cooled and initially moisturized by quench cooling the pulverulent solids with a coarsely distributed liquid followed by final moisturizing with a finely divided spray. The quench cooling and initial moisturization takes place in apparatus having agitation and blending sections or zones while final moisturizing takes place in a moisturizing section or zone where water or moisture is introduced through a finely divided spray.  This staged moisturizing process is an improvement over the heretofore process of one stage moisturizing to desired levels with a fine spray only, since it provides for utilization of nozzle-clogging particulate-containing waste streams and effluents for initial moisturization of the spent shale.

Abstract: A PRESSURE REGULATING VALVE     ABSTRACT OF THE DISCLOSURE     The valve comprises a body in the shape of a cup whose edge portion is secured around an aperture in a wall of an enclosure.   An annular T-shaped partition wall divides the interior of the body into two chambers which communicate respectively with the interior of the enclosure and with the outside atmosphere.  Ports extend    respectively through the vertical leg and the branches of the T.  An elastically yieldable sleeve whose axial section is in the shape of a lily is a grip fit on the vertical leg of the T and is applied by its annular flange against the inner surface of the body.          This arrangement both allows the gases within the en-closure to escape by way of the port in the vertical leg of the T in the event of over-pressure and allows air to enter the enclosure by way of the ports in the branches of the T in the event of a depression in the enclosure.          This valve may be easily added to various types of automobile fuel tank filler caps.

Abstract: ABSTRACT          COATING FOR BIOPROSTHETIC DEVICE                AND METHOD OF MAKING SAME           A coating and integral treatment for improv-ing the biophysical stability of bioprosthetic devices after implantation, particularly with respect to cal-cification, and, specifically, a method for treating animal tissues,  such as heart valves, to provide improved biophysical stability in allograft and heter-ograft transplantations.   The increased stability results, in-part, from the creation of a three-dimen-sional matrix of a primary strucutral component of the prosthetic device and covalently attached calcifica-tion inhibitors.   Other materials, some having addi-tional  stabilizing effects, may be utilized to form additional bridges or fill the interstitial gaps in the matrix.   After implantation, the resultant modi-fied device exhibits minimal surface for intramatrix growth of calcium phosphate crystals, and additional-ly, may inhibit platelet aggregation, enzymatic degra-dation and host rejection, while minimizing the risk of mechanical failure, in the host organism.

Abstract: ABSTRACT OF THE DISCLOSURE      An improved housing construction for electrical apparatus is disclosed, the housing having particular utility as a housing suitable for an ionization detector array of a tomographic x-ray scanner.  The housing comprises at least two mating sections which, upon assembly and juxtaposition one to another, form a closed interior chamber adapted to receive the detector array, or other electrical apparatus.  A gasket means preferably comprising a so-called "flexible" printed circuit constructed of a suitable polymer plastic is provided between the assembled mating sections of the housing to effect a sealing of the interior chamber.  Electrical conductors, such as a metallic printed circuit foil, are disposed within the polymer material and extend between the interior chamber and the exterior of the housing.  The conductors define means by which electrical connections can be made to electrical apparatus within the chamber, such as the detector array, and external circuitry.        This construction eliminates the necessity of providing separate conductor feedthroughs in the housing.  Further, the sealing of the chamber is enhanced through the provision of O-ring seals disposed in the mating surface of each of the two mating sections of the housing, the sealing rings being laterally offset one from the other such that when the mating sections are assembled and juxtaposed with the gsket means therebetween, the O-shaped sealing rings are staggered.

Mistracking, whereby the receiver fails to faithfully reproduce the original input signal because its pole-based predictor coefficients differ from those of the transmitter predictor, which can result from transmission errors when the original signal comprises two pure tones, is avoided by eliminating the dependence of the adaptation process upon the predictor output.  This is achieved by deriving the coefficients using the difference signal but not the reconstructed signal.  In particular, the prediction coefficients may be derived in accordance with the expression:-  - i -
