Abstract: ABSTRACT       An electronic security system for detection of a resonant tag circuit even in the presence of a substantial-ly identical spurious resonance.  The spurious resonance is fixed or quasi-stationary in time, in relation to the time that a resonant tag circuit is present in a security system. A representation of the quasi-stationary noise is stored in an electronic memory and is subtracted from a received signal to automatically cancel the interfering noise.

Abstract: IMPROVED FLUIDIC OSCILLATOR AND   SPRAY-FORMING OUTPUT CHAMBER                     ABSTRACT         A fluidic oscillator includes a chamber having a common inflow and outflow opening into which a jet is issued in a generally radial direction.  After impinging upon the far chamber wall the jet is redirected to form a vortex on each side of the incoming jet.  The vortices alternate in strength and position to direct outflow through the common opening along one side and then the other of the inflowing jet.  A spray-forming output chamber is arranged to receive the pulsating outflows from the aforementioned or other fluid oscillator and establish an output vortex which is thereby alternately spun in opposite directions.  An outlet opening from the output chamber issues fluid in a sweeping spray pattern determined by the vectorial sum of a first vector tangential to the output vortex and a function of the spin velocity, and a second vector, directed radially from the vortex and determined by the static pressure in the chamber.          By increasing or decreasing the static pressure, or by increasing or decreasing the vortex spin velocity, the angle subtended by the sweeping spray can be controlled over an unusually large range.  By properly configuring the oscillator and/or output chamber, concentrations and distribution of fluid in the spray pattern can be readily controlled.

Abstract: Case I                   ABSTRACT OF THE DISCLOSURE        A speech recognition method for detecting and recogniz-ing one or more keywords in a continuous audio signal is dis-closed.  Each keyword is represented by a keyword template re-presenting a plurality of target patterns,and each target pattern comprises statistics of each of a plurality of spectra selected from plural short-term spectra generated according to a predetermined system for processing of the incoming audio.          The spectra are processed to enhance the separation between the spectral pattern classes during later analysis.  The processed audio spectra are grouped into multi-frame spectral patterns and are compared by means of likelihood statistics with the target patterns of the keyword templates. A concatenation technique employing a loosely set detection threshold makes it very unlikely that a correct pattern will be rejected.

Abstract: A carton or package for packaging semi-fluid material which can be hardened by freezing, such as ice cream, sherbet, and the like, is formed from specially constructed integral carton blank and a special process for assembling the same.  The carton blank has a front panel, a bottom panel, a rear panel, a cover panel, and a front cover sealing flap articulated one to the other in the order named, with end-forming flaps and glue-flap extensions extending later-ally therefrom adapted to be glued together to form inner and outer walls and side-cover flaps.  The bottom outer wall-forming flap is glued to the inner wall-forming flaps by glue strips along the side edges the latter, where they are joined to the front and rear panels, and the side-cover flap has a tuck-in tab adapted to be tucked in under the bottom outer wall-forming flap between the glue strips.  The glue-flap exten-sions are adapted to fold over the side-cover flaps and to be glued thereto by an extension  of the glue strip adjacent the front of the carton.  In forming the carton or package, one end is closed first by folding in the side flap extensions, folding down the side-cover flap, applying the glue strips with the one adjacent the front of the carton extending up over the folded-down side-cover flap, then folding up the bottom outer wall-forming flap to a position overlying the tuck-in tab and folding in the glue-flap extensions over the glue strip on the side-cover flap and causing adherence between the glue and the folded-in flaps.  The tube thus formed is then filled and the other end closed in a like manner.

N-Formylanilido aromatic compounds containing at least two electron-withdrawing substituents in the benzene ring are obtained by reacting together equimolecular quantities of a formanilide and an aromatic halogen compound in the presence of a diluent and an acid-binding agent at a reaction temperature below that which causes decarbonylation.  The corres-ponding anilido aromatic compounds are obtained by conducting the process at a reaction temperature above the temperature of decarbonylation or by heating the N-formylanilido aromatic compounds above their temperature of decarbonylation.

Abstract: Abstract of the Disclosure The reaction of an organic polyisocyanate with an organic compound containing at least 2 active hydrogen containing groups is catalyzed with a synergistic co-catalyst combination of at least one organo-mercuric catalyst and at least one zinc salt of an alkylcarboxylic acid having about 2 to about 22 carbon atoms wherein the organo-mercuric com-pound is selected from the group consisting of (1) the divalent mono-mercury salts of organic acids and (2) the ionizable mono-organo-mono-mercuric carboxylates or poly-carboxylates containing only one carbon to mercury bond which are inert to isocyanate-active hydrogen reactions.

Abstract: Abstract of the Disclosure Originals are individually separated from the bottom of a stack overlying the imaging platen of a document copier and are advanced around a first 180° bend onto the platen for copying.  After they are copied, the originals are returned to the top of the stack around a second 180° bend at the other end of the platen.  Each original is advanced to the imaging platen a number of times equal to the number of copies to be made to produce collated sets of copies from the copier.  A relatively flat place-marking member initially placed on the uppermost original drops down when that original is fed to generate a signal indicating that the entire set of originals has been advanced once to the imaging platen.  The generated signal indexes a counter that turns off the feeder when the desired number of copies have been made.  This counter also actuates a motor that shifts the copy tray between sets to offset succes-sive sets of copies.

Abstract: ABSTRACT OF THE DISCLOSURE     A heterogeneous specific binding assay method and test means for the simultaneous determination of each of a plur-ality of different ligands (e.g., antibodies, antigens or haptens) in a single liquid test sample.  The assay may follow any conventional technique of a heterogeneous type, i.e., which includes a separation of a bound-species from a free-species form of the labeled reagent.  The combined assay is accomplished by using solid-phase binding agents for the respective ligands to be determined which are differentially separable from each other, thereby permitting the use of a single label rather than a different label for each ligand to be determined.  The assay is particularly suited to the simultaneous determination of different antibodies, particu-larly antibodies to different viral antigens, in a single serum sample.

A further synthetic resin layer is applied to the interior wall of the tube during its formation.  The resin layers are subjected to a first curing step during the formation.          Then an exterior coating of a synthetic resin layer is applied and, finally, all resin layers are subjected to a final curing step.  The invention makes it possible to produce the tubes in a single, continuous operation.
