Abstract: A waterproof body for an electric cautery containing cautery parts, comprising a cautery tip assembly, a first hollow half body with a button hole in its side and a receptacle in one end so as to receive the cautery tip assembly, a second hollow half body with a receptacle in on end to receive the cautery tip assembly, a waterproof flexible membrane fastened to the inside of the first half body so as to seal the button hole in a waterproof manner, and an electrical switch button fastened in the button hole of the first half body. The first and second half bodies are joined together in a waterproof manner by ultrasonic welding. The electrical switch button slides in an axial manner relative to the body.

Abstract: A self-healing data network and network node controller. Data transmission of data cells to form message permitting self-clocking operation of each node and elastic buffering implemented to allow receipt of messages without regard to the phase of messages allows asynchronous operation of each node relative to other nodes. Fault detection and network self-healing are performed by each node independently of other nodes.

Abstract: A method of assembly for small electrical devices which enhances automated assembly opportunities while reducing costly and nonuniform hand operations, by including the use of flexible connectors, anisotropic adhesives, three dimensional molded circuit boards and elastomeric connectors.

Abstract: A process for conditioning a gas containing the vapors of a volatile substance, in which the gas is placed sequentially in contact with successively more concentrated solutions of an absorption liquid on cooled surfaces, such absorption liquid consisting of a solution of said volatile substance and at least one non-volatile substance. The vapors in the gas are isothermally absorbed into the absorption liquid upon such contact, thereby diluting the concentration of the absorption liquid. The diluted absorption liquid is concentrated by multi-stage evaporation in a multi-stage evaporator. The concentrated absorption liquid is recycled back to the cooled surfaces.
