Abstract: A method for introducing gas like oxygen, air or carbon dioxide into water, in which a water flow enriched in the gas is passed through a reaction chamber so that the flow rotates around and moves along the Longitudinal axis, a sudden pressure minimum is provided in a section of this axis where gas comprised in the flow gets collected and mixed with vapor, the pressure is increased after the minimum, whereby gas is swallowed by water so that gas molecules get bound to water molecules. The apparatus for carrying out the method comprises a closed recirculating path with the reaction chamber, the flow is maintained by a pump, and the gas is introduced in the water either by a vortex stream or by a water jet pump. The so obtained water comprises the gas in stable and bound state in a concentration exceeding normal saturation. The dielectric constant and certain physical parameters of such water differ from those of pure water.

Abstract: The present invention provides a process for the currentless deposition of lectropositive metal layers on to appropriate less electropositive metals by contacting an object to be coated with a coating bath, wherein a coating bath is used which contains a metal complex obtained by reacting a monovalent electropositive metal halide with a base, which is capable of complex formation with the electropositive metal, and a hydrohalic acid.The present invention also provides a coating bath for the currentless deposition of electropositive metal layers on to less electropositive metals, wherein said bath contains an electropositive metal complex obtained by reacting a monovalent electropositive metal halide with a base which is capable of complex formation with the electropositive metal and a hydrohalic acid.

Abstract: A stabilized, aqueous, alkaline gold bath is disclosed, containing a dicyanogold(I)-complex, a complex-former, an alkali hydroxide and a reducing agent, for the electro-less deposition of gold onto gold, metals which are more electro-negative than gold, as well as alloys of these metals, characterized by a content of at least one compound from the classes of glycol derivatives and polyethylenimine, as stabilizer.

Abstract: Disclosed is a push button apparatus for operating a flush valve or the like of a water closet, comprising button actuator means including a button and housing, said housing having a shank for passing through an opening in a water closet tank wall, the button having an actuator within and reciprocally movable relative to said housing shank. Means are provided for securing bracket means to the button shank in a predetermined orientation therewith. Means are provided for actuating lever arm means. Means on the bracket means and the lever actuating means for mounting the lever actuating means for pivotal movement relative to the bracket means upon reciprocal movement of the button actuator operatively contacting the cam means. The mounting means comprises pivot means and pivot socket means with means providing lateral access to the socket means.

Abstract: An automatic impedance matching network for a transmission line includes an impedance monitor which provides a control signal for two variable compensators. One compensator corrects an impedance mismatch at low frequencies while the second compensates within a higher frequency range. A directional sensor completes a conductive path for the control signal to the variable compensators only for the direction of signal propagation indicative of the impedance of the transmission line being compensated. The disclosed arrangement operates automatically from the intelligence signals transmitted over the line to provide impedance compensation for a variety of cable sizes of different lengths.

Abstract: A foldable support, adapted to be mounted on a vertical wall, includes an elongated vertical housing, and an arm having an end portion pivotally mounted on a lower portion of the housing and adapted to be selectively moved between a raised position at which the arm is concealed within the housing, and a lowered position at which the arm projects horizontally outwardly therefrom. The housing has a channel-shaped transverse cross-section formed by a pair of transversely-spaced vertical flanges separated by an intermediate vertical web. The pivoted end portion of the arm has a U-shaped cross-section provided with a pair of trunnions which are journalled in a pair of bearing openings provided in the housing. When the arm is moved to the lowered position, an object, such as a clothes hanger, may be hung therefrom.
