Abstract: ABSTRACT     DISCRETE FOURIER TRANSFORM EQUALIZER AND METHOD     A method of determining the initial values of the co-efficients of a transversal equalizer which includes the steps of: transmitting a periodic sequence such as a pseudo-random sequence over a transmission channel; modulating the received signal by means of a time-domain window whose Fourier transform exhibits a relatively flat central peak and has a low value in the vicinity of those frequencies which are multiples of the inverse of the period of the transmitted sequence, which low value may result, for example, from the existence of double zeros in the Fourier transform; calculating the discrete Fourier transform Wk of the signal so modulated; calculating the ratio Fk=  where Zk is the discrete Fourier trans-form of the transmitted sequence; and calculating the inverse discrete Fourier transform of Fk, thereby deter-mining the value of the coefficients cn of the equalizer.

Abstract: ABSTRACT OF THE DISCLOSURE              The invention comprises a rectangular plastic sheet which may be folded about living hinges to provide a container for holding coins and the like.  The sheet is made of polypropyl-ene or other suitable plastic material which has good living hinge qualities in thin sections.  The preferred embodiment consists of three V-shaped units separated by two living hinges, which units when folded form a regular hexagonally cross-sectioned cylinder.  Ledging may be provided on the end of the sheet so that when folded the ledging at least partially closes the otherwise open ends of the cylinder.  A locking mechanism comprising an upwardly extending lip on a side edge of the sheet which engages a hollow behind and beneath a downwardly extending lip on the other side edge is provided.  By forcing contact by the coins against the container walls when the container is closed  the material is tightened against the coins and the locking mechanism becomes more tightly engaged, securing against accidental opening.  Because of the construction, less plastic is needed to make this container than known horseshoe-cross-sectioned coin holders.

Abstract: ABSTRACT OF THE DISCLOSURE       This disclosure relates to a method, a rubber skim stock and a product containing the skim stock having improved adhesion between a metal member and a contiguous rubber skim stock.  The invention lies in a discovery that improved rubber-to-metal adhesion can be obtained by adding to an otherwise conventional rubber skim stock compound appropriate amounts of either p-aminobenzoic acid or a transition metal salt of p-aminobenzoic acid.  In particular, the cobalt and nickel salts of p-aminobenzoic acid have been found to be effective.         The method of this invention comprises the steps of mixing the p-aminobenzoic acid or transition metal salt of p-aminobenzoic acid into a rubber compound, forming this compound into contiguous relationship with a metal member in an unvulcanized product and vulcanizing the product to yield the end product.

Abstract: ABSTRACT The present invention is directed to electrical connectors of a type providing protection from electromagnetic interference (EMI),  While multiple contact filter connectors of the prior art have proven successful when used to conduct relatively low RF currents of approximately one-quarter ampere they have not been suitable for conducting high RF currents of, for example, three or more amperes.  Because the ground plates are thin, the heat generated by high current conduction cannot be adequately dissipated. As a result, the connectors overheat and, ultimately, fail.  The present invention overcomes these deficiencies of the prior art by providing an improved multiple contact filter connector capable of accommodating high RF currents and a method of manufacturing the same.  The connector includes an outer metalic shell, a dielectric body within the shell and at least one network filter contact assembly.  The inner body has at least one through channel and a transverse cavity which communicates with the shell and the channel.  The network filter contact assembly has a ground electrode and a pin electrode and Is disposed within the portion of the channel bridging the cavity.  Conductive curable filler material is charged into the cavity around and in contact with the ground electrode to efficiently and inexpen-sively establish a ground plate for the connector.  A retention means disposed within the channel and a locking means carried by the contact cooperate to provide axial strain relief, thereby protecting the bond between the conductive filler material and the ground electrode.
