Abstract: ABSTRACT OF THE DISCLOSURE                 Novel water soluble, inorganic complexes are obtained by reacting, in the presence of aqueous ammonia, at least one non-alkaline metal selected from Groups 1-VIII of the Periodic Table with an alkali metal hydroxide.  An excess of the non-alkaline metal or metals is introduced into a reaction vessel, preferably already containing the aqueous ammonia, and the alkali metal hydroxide is thereafter incrementally added in such manner as to create localized areas of high concentration and pH approaching a value of 14.  The hydro-oxide in these areas of high concentration, in combination with reactive NH2 groups provided by the aqueous ammonia, causes erosion of the non-alkaline metal, the formation of non-alkaline metal ions and the production of a monomeric, metal amide complex. The reaction parameters are maintained such that the rate of addition of alkali metal hydroxide is sufficient to suppress the expulsion from the system of ammonia gas while at the same time producing an overall endothermic reaction in which the ions of the alkali metal, the non-alkaline metal and the NH2 groups react to produce an inorganic complex.  If the endothermic reaction is maintained and sufficient excess non-alkaline metal is present in the aqueous medium, after a period of time the reaction will enter an exothermic phase, producing an in-organic complex produced during the endothermic phase of the reaction has valuable utility in the production of soaps and bleach products.  The inorganic polymeric complex may be used in aqueous solution for both electroless plating and electro plating of the non-alkaline metal.

Abstract: C. Matheny - 4 LINK CIRCUIT FOR INTERCOM UNIT     ABSTRACT OF THE DISCLOSURE: An intercommunication link for a multiple link key telephone system with a combination lamp-button on each handset for each available link. In each link, a line seeking intercom service is sensed to operate a relay in the link selected. A lamp flash signal on the lamp of the selected link is initiated. In this condition, all other links are disabled and none can be accessed when one link is in the lamp flashing condition. The called local number of the desired intercom station is dialed and when the called station line is answered, a second relay in the selected link operates to release the first relay. On operation of the second relay, a steady lamp indication is sent to both stations in the conversation. Other free links may be accessed at this time. Thus, only during this intercom signaling phase are the remaining free links affected.

Abstract: DIGITAL DETECTION SYSTEM FOR DIFFERENTIAL         PHASE SHIFT KEYED SIGNALS                           ABSTRACT      A digital detection system for binary differential phase shift keyed (DPSK) signals includes first and second multipliers to which the signal is applied, and which receive reference signals applied in quadrature to the two multipliers.  The outputs of the multipliers are each applied through a filter to a one bit delay circuit, with the outputs of the filters and delay circuits being applied to third and fourth multipliers.          The outputs of the third and fourth multipliers which receive signals from the two filters are summed to provide the detected digital signal.  The filters may be matched filters each including an integrate, sample and dump circuit, and a data transition tracking loop coupled to the first multiplier and to the detector system output provides a bit synchronization signal for the matched filters.  An I-Q loop may be coupled to the outputs of the two matched filters and controls an oscillator which provides the reference signals for the first and second multipliers.  The addition of two multipliers and three summing circuits can extend the detection system for use with quaternary (four-phase) differential phase shift keyed signals.
