    • A process is proposed for liquefying a hydrocarbon-rich fraction (A), especially natural gas, by a) liquefying the hydrocarbon-rich fraction (A) against the coolant mixture of a cooling circuit, b) compressing the coolant mixture in at least two stages (C1, C2), c) partially condensing (E1) the compressed coolant mixture (2) at least downstream of the penultimate compressor stage (C1), d) compressing (C2) the lower-boiling gas fraction (2′) obtained to the final pressure, e) while cooling (E) the first higher-boiling liquid fraction (3) obtained, expanding it (a) to perform cooling and vaporizing it (E) against the hydrocarbon-rich fraction (A) to be cooled, f) partially condensing (E2) the coolant mixture fraction (4) compressed to the final pressure and separating the first lower-boiling gas fraction (5) obtained, after partial condensation (E), into a second lower-boiling gas fraction (7) and a second higher-boiling liquid fraction (6), and g) liquefying and subcooling (E) the second lower-boiling gas fraction (7), sub-cooling (E) the second higher-boiling liquid fraction (6) and expanding the two fractions to different temperature levels to perform cooling (b, c), and partly heating and at least partly vaporizing them (E) against the hydrocarbon-rich fraction (A) to be cooled. According to the invention, the composition of the coolant mixture is selected such that the final boiling point (dew point) of the second lower-boiling gas fraction (7) is at a lower temperature than the initial boiling point of the first higher-boiling liquid fraction (3).

    • A potentiometer assembly particularly suited for supplying tuning voltages for all of the bands of signals capable of receipt by a television receiver or the like, includes three segments of resistive material arranged in a circle on a support member. Each of the segments corresponds to a different band of frequencies to which the television receiver may be tuned. Band selection is effected by comparable conductive segments on the support member.In one embodiment, a single wiper is used to sweep all of the resistive segments to supply the desired tuning voltage output. A cam arrangement is used to adjust the detented position of the wiper relative to the support member to effect fine tuning at each position. Other embodiments utilize individually adjustable wipers for each station or detent position of the tuner, with each wiper being preset to effect the fine tuning at the detented position of the potentiometer assembly. The individual contacts or wipers for each position are arranged to overlap comparable resistances on the resistive material, so that the entire range of tuning voltages which appear across the resistive material is available from the outputs of the assembly.

    • Apparatus for injection of compressed air into a liquid such as waste water comprises a tubular basic body surrounded by a flexible, perforated membrane through which compressed air is supplied through radial openings in the basic body to be dispersed by the perforated membrane as fine bubbles into the liquid. The basic body is connected to a compressed air supply pipe through a hollow connecting body that supports the basic body and supplies compressed air to radial openings in the basic body. In one embodiment, air-conducting passageways are arranged concentrically about the hollow connecting body. The hollow connecting body provides a flooding zone in communication with the tubular basic body and sealed from the air-conducting passageways. Liquid flows therethrough to avoid dead zones of untreated liquid. The common flooding zone provides a floodable volume relative to a non-floodable volume of greater than 1.3.
