Abstract: ECHO CANCELLATION USING TRANSVERSAL FILTERS            Abstract of the Disclosure A transversal filter echo canceller includes two stores each for storing a set of coefficients for the transversal filter.  The suitability of a set of coefficients stored in one of the stores is checked by supplying a pulse to the receive path and transversally filtering it, and comparing the level of the resultant transmit path signal, after subtraction of the transversally filtered pulse, with a threshold.  At the same time the impulse response before the subtraction is stored in the other store.  If the threshold is exceeded the functions of the two stores are interchanged and the check is repeated.  The checking can be effected only once for a transmission line not subject to change, or, in the case of a transmission line which is subject to change, at the start of each telephone connection established via the line and optionally during conversation pauses during the connection.                               -i-

Abstract: ABSTRACT OF THE DISCLOSURE An improved process for preparing stable partially quaternized amino methylated acrylamide polymers which are in the form of water-in-oil emulsions, which emulsions are thermally stable and readily invert in alkaline waters which comprises the steps of:  preparing a formaldehyde adduct of a secondary amine containing 2 - 8 carbon atoms as a 0.1 to 55% by weight aqueous solution; adding the formaldehyde adduct in an amount sufficient only to aminomethylate between 5 - 80% of the acrylamide groups therein to a water-in-oil emulsion of a finely divided acrylamide polymer reacting the acrylamide polymer with the formaldehyde adduct; reacting said partially amino methylated acrylamide poly-mer contained in the water-in-oil emulsion with more than 6% by weight based on the water in the emulsion of sodium bisulfite to provide a stabilized water-in-oil emulsion; and finally reacting the water-in-oil emulsion of a finely divided stabilized amino methylated acrylamide polymer with a quaternizing agent containing 1 - 7 carbon atoms.  These modified polymers exhibit higher thermal stability and better solution characteristics after long term storage than the known acrylamide polymers.

Abstract: ABSTRACT        High emulsifier levels and freely available water in baked-good doughs provide dough systems with an apparent lipid-continuous, rather than sugar syrup-continuous liquid phase. When this lipid-continuous system is present, the contact surfaces of the dough mass exhibit the non-sticky character of a shortening, rather than the inherently sticky character of a sugar syrup.  The dough can then be easily rolled, extruded, scooped, etc., with minimal adherence to mixing and forming equipment surfaces.
