Abstract: There is disclosed an automatic or semiautomatic firearm having one or a plurality of parallel rail attachments for weapon attachments (accessories) with a central power source capable of powering the accessory devices electrically connects through a series of parallel rails circumferentially surrounding a barrel of the firearm. More specifically, there is disclosed a central power source to power up one or a plurality of rail accessories that provides power to each rail accessory through, preferably, a copper or brass strip located on each rail element. In addition, there is disclosed a method for transmitting information among and between weapon attachments using the rails as an antenna and radio frequency transmission of digital or analog signals to receiver units in each attachment of within a central bus.

Abstract: A solid phase synthesis method for the preparation of diverse sequences of separate polymers or nucleic acid sequences using electrochemical placement of monomers or nucleic acids at a specific location on a substrate containing at least one electrode that is preferably in contact with a buffering or scavenging solution to prevent chemical crosstalk between electrodes due to diffusion of electrochemically generated reagents.

Abstract: A mixed polymer material is formed of a polyelectrolyte ternary copolymer having a hydrophobic backbone and containing 10 to 90 percent unsubstituted portions and the remainder being substituted with hydrophilic groups such as a styrene ternary copolymer of the formula: ##STR1## where R.sup.1 is alkyl, preferably ethyl, and R.sup.5 is hydroxyalkyl, preferably hydroxethyl. The ternary copolymer self-segregates into discrete hydrophilic and hydrophobic domains and is believed to act as a template to segregate the polyelectrolyte into the domains. The mixed polymer has large ion-exchange capacity, very high effective diffusion constants of incorporated counter-ions and prolonged retention of multiply-charged counter-ions. The mixed polymer forms a stable and effective coating for electrodes for electrocatalytic applications.
