Abstract: The invention relates to a mass flow meter operable on the Coriolis principle having two rectilinear juxtaposed parallel arranged measuring tubes mechanically interconnected at their ends. An oscillator between the tubes produces opposite oscillatory movement of the tubes with a harmonic oscillation superimposed on the fundamental oscillation. Sensors between the tubes on opposite sides of the oscillator sense relative movement between the tubes and generate signals corresponding thereto. A circuit responsive to these signals determines resonant frequencies of the fundamental and harmonic oscillations and derives therefrom a correcting value which gives effect to axial stresses in the measuring tubes to determine a corrected mass flow.

Abstract: In a vapor burner for liquid fuel there is an electrically heatable gasifying chamber (1), a passage system (K) concentric therewith for supplying air of combustion, and a burner tube (26) which surrounds a combustion chamber (25) and is bounded at the rear by an annular closure wall (22). The gasifying chamber (1) is formed substantially by a central gasifying tube (2). Guide means (19) serve to produce an external annular eddy (31) of combustion gases that extends along the inside (33) of the burner tube (26) rearwardly at least over a section disposed axially in front of the mouth (23) of the passage system (K). An ionisation measuring electrode (35) placed in the backward flow permits the flame to be accurately detected independently of the flame front which changes with a change in the burner output. When the burner tube (26) glows, there is automatic re-ignition if the flame blows off.

Abstract: The invention relates to a thermostatic type of mixer tap having hot and cold water inlets and outlets for discharging water at an intermediate temperature controlled by a thermostatic valve unit. The mixer tap has a mixing chamber to which apportioned amounts of hot and cold water are admitted by the thermostatic valve unit and outlet valve for controlling the flow from the mixing chamber to the outlet. For drinking purposes there is provided a bypass conduit which extends from the cold water inlet to the outlet valve which bypasses the mixing chamber. The outlet valve is operable to selectively connect either the mixing chamber or the bypass conduit to the outlet as desired.
