Abstract: Abstract of the Disclosure A control current generator for generating control currents of different  magnitudes representing respective functions, and having particular application in a central dictation system.  A constant current generator generates a constant current whose magnitude is determined by the resistance connected to the constant current generator. A plurality of resistors having different values is provided to be individually connected to the constant current generator, and thereby establish the magnitude of the constant current generated thereby.  In addition, a signal generator is provided for super-posing a characteristic signal onto the constant current generated by the constant current generator, this signal generator being selectively energized in response to the operation of predetermined control switches.  When differ-ent control switches are operated, the constant current of corresponding magnitude is generated without the superposed characteristic signal.

Abstract: ABSTRACT OF THE DISCLOSURE         A self-extinguishing circuit interrupter wherein a pair of separable contacts is disposed within an arc extinguishing gas.       Energy of an electric arc established between the separated contacts is utilized to increase the pressure of the arc ex-tinguishing gas, and the high pressure gas thus generated is introduced into a pressure chamber to be stored therein.  When the arc current approaches zero, the high pressure gas within the pressure chamber is puffed to the arc to extinguish it.  A plurality of pressure chambers are axially disposed, i.e., in the direction in which the movable contact moves, thereby improv-ing the arc extinguishing capability of the circuit interrupter.

Abstract: ABSTRACT OF THE DISCLOSURE.           A method and composition for destroying pest insects in their aquatic stage and other pest-life forms over a sustained period of time, by the gradual and continuous release of an organotin substance from an inert thermoplastic medium.  The composition comprises an organotin of extremely low water solu-bility bound in an ethylene vinyl acetate copolymer, in which said organotin is insoluble and in which said organotin is uni-formly dispersed with an inert coleachant of moderate water solubility. When this formulation is brought into contact with water, the coleachant gradually solvates into the water creating and enhancing the development of porosity within the thermo-plastic phase.  Said organotin agent, interspersed within the thermoplastic matrix, contacts the entering water and egresses as molecular aggregates being washed through the pore system and into the external watery medium.  Such aggregates being toxic to mosquito larva, other insects and various other pesteferous life forms, upon continuous exposure, leads to a condition of terminal chronic intoxication.
