Abstract: In a method and an apparatus for separating water and solid particles from an oil, the oil is supplied to a treatment step in which the water in the oil is evaporated and components dissolved in the water are precipitated as solid particles. In order that each separate water element in the oil shall have a short distance to reach an outer surface of the oil, said treatment step preferably takes place when the oil is spread out, either in small drops and/or a thin layer. After this treatment step and with the treated oil separated from the water vapour, a particle separation from the oil takes place not only of particles formed by the precipitation but also of other particles in the oil, if any.

Abstract: Electrically polarizable material (12), e.g. PVDP (film) is poled by appliyng an electric field across the film. Insulation is provided on the surface of the film. In a typical embodiment a compliant dielectric annulus (10) insulates the polarized region from the edges of the film. This substantially eliminates breakdown at the edges of the film, allowing increased poling voltages. The technique can reduce poling time to typically a few seconds at room temperature, as compared to minutes or hours by prior art techniques, some of which required elevated temperatures.

Abstract: To protect the pump of a whirlpool bath against running dry and against blockage at the inlet, a pressure (or flow) sensor 14 senses pump pressure and generates a signal to keep a switch S2 in the pump motor electrical supply circuit closed. If the pressure signal ceases owing to blockage orrunning dry, the switch S2 opens. A manual override button 15 is held ON to close switches S1a and S16 in the power circuit for start-up. The sensor 14 and manual button 15 are preferably air pressure devices. Switch S1a is preferably an air-signal-operated latching switch whereby with the pump operating, the button 15 can be operated to switch the pump off. Relays RLA 1 and 2 may be used in conjunction with the electrical switches. A bleed hole may be provided between the button 15 and switch S1b to limitthe period of time for which the motor could be run, with the bath empty, by prolonged inadvertent actuation of the button 15.

Abstract: The invention relates to a water jet aerator which, in place of conventional metal screens, has at least two separate staircase-like obstacles, which project laterally into the paths of the individual jets and split up the jets, and mix them with air. Several such obstacles are arranged in the immediate proximity of one another, successively in the direction of flow, so that a cohesive, well-ventilated jet is obtained. The configuration of the jet cross-section can vary as a function of the arrangement of the facing walls defining the flow path in the area of the obstacles.

Abstract: @ A switching system for a network having terminal control equipment units (31 to 3n) connected to a network termination unit (2), in which terminal control equipment units (31 to 3n) of the same kind are connected with an exchange (1) through a subscriber's line which has assigned to it a single subscriber number and which has a plurality of communication channels, the system including storage units for each terminal control equipment unit of the subscriber's line for storing call statuses of incoming calls. When a first incoming call is received, the storage units of the terminal control equipment units (31 to 3n) set respective call statuses for the first incoming call to a ringing state. When a second incoming call is received before a response to the first incoming call is transmitted, the storage units also set the call statuses for the second incoming call to a ringing state. When any one of the terminal control equipment units (31 to 3n) in the ringing state delivers a response, the call status for the first incoming call of the terminal control unit delivering the response is set to an active state and the call statuses for the first incoming call of the other terminal control units in the ringing state are released. The call statuses for the second incoming calls are maintained.
