Abstract: Abstract of the Disclosure:     In a self-adaptive echo canceller responsive to a receive-in signal and an echo signal resulting from the receive-in signal, a learning identification technique is implemented so as to exempt a send-out signal from the echo signal by successively varying an amount of modification (.DELTA.hj') represented by .beta.eX. where .beta. represents a coefficient; e, a level of the send-out signal; and X, a level of the receive-in signal.  A coefficient calculating circuit (28, 30, 35) calculates the coefficient .beta. from the factor and an incoming level (X) of the receive-in signal to determine the amount of modification.  The coefficient is accompanied by a modifier given by        where K represents a constant.  The coefficient calculating circuit includes a unit (35) for calculating the modifier.          The modifier may be multiplied by various factors of the amount of modification.     [Fig. 1]

Abstract: SURFACTANT AND PHARMACEUTICAL COMPOSITIONS CONTAINING SAME             ABSTRACT OF THE DISCLOSURE  A surfactant having the capacity of reducing the surface tension in pulmonary alveoli significantly is provided. The surfactant consists essentially of, based on the total weight of the surfactant, 50.6-85.0% of a choline phospho-glyceride, 4.5-37.6% of an acid phospholipid, 4.6-24.6% of a fatty acid or its analogue and 0.1-10.0% of a lipoprotein derived from the lung of a mammal.  These components co-operate to form a kind of film at a gas-liquid interface, within pulmonary alveoli and reduce the surface tension. A pharmaceutical composition comprising the surfactant is useable for the clinical treatment of respiratory distress syndrome.

Abstract: Application Of: Richard W. Elbers, Jr.          For: Corrugated Spacers For Pleated Air Filter Media And Method Of Fabricating The Same Abstract Of The Disclosure An improved corrugated sheet aluminum spacer for use in pleated media air filters is disclosed. The spacers are folded in zig zag fashion along one edge in a succession of V formations having a first height and width, and along the opposite edge in a succession of V formations having both heights and widths approxi-mately  one-fifth of the first height and width. Since the fold lines are substantially parallel, there are five V formations within a given width of the opposite edge for each one along the first edge, the fold lines of the intermediate V formations extend-inq from the second edge only a portion of the distance to the first edge, but preferably about 90% of the length of the sheet.          The V formations are formed by passing the aluminum between a pair of rolls with forming blades having overlapping edges which engage the sheet. The height or amplitude of the V formations at the small end is on the order of .03 to .04 inches in aluminum sheet having a thickness of 1 to 2 mils, preferably .0015 inches.          The 5 to 1 ratio of V formations along opposite edges is achieved by polishing the surfaces of the forming blades which contact the sheet to a degree providing surface irregularities of not more than about 10 microinches, preferably in the range of 4 to 8 micro-inches. The method of fabricating such spacers is also disclosed.

Abstract: Abstract of the disclosure The invention relates to a device for folding and sealing the head of a folded carton made out of a web or blank of cardboard coated on the inside with a thermoplastic layer.    The device has levers or supports that carry the folding and pressure-welding tools and that are powered independently of each other by shafts.  The result is a structure that is simple and easy to clean.  It also allows satisfactory acceptance or introduction of force for the pressure-welding process.  Since the force-introduction impact point and a point of contact between the tools that are to be approached to each other like tongs can be located on an axis of pressure, the shafts that pivot and power the lever and support need to accept no forces and accordingly remain free of stress.

The process embraces the discovery that compounds such as polyhydric alcohols and polyethylene glycol-(400) desensitize the L-phenyalanine ammonia lyase enzyme to substantially higher substrate concentrations than practiced heretofore.  In addition, polyhydric alcohols and polyethylene glycol-(400) substantially enhance the instantaneous rate of reaction and inhibit inactivation of the L-phenylalanine ammonia lyase enzyme over longer reaction periods.
