Abstract: A carbonation machine includes a rotatable carbonation head including at least one pressure release valve, a carbonation tube connectable via piping to a gas canister and a flange for engaging a neck of a bottle filled with liquid to be carbonated by screwing the neck into or onto the flange to firmly hold the bottle with the carbonation tube maintained inside the bottle, and for disengaging the neck of the bottle from the flange by unscrewing the neck off the flange. The rotatable carbonation head is configured, when screwing the neck into or onto the flange, to be rotated from a release position to a lock position, and is configured, when unscrewing the neck off the flange, to be rotated from the lock position to the release position. In the release position said at least one pressure release valve is operated to open so as to release excess pressure if such excess pressure exists in the bottle, and in the lock position said at least one pressure valve remains closed.

Abstract: A measurement system and method are presented for measuring one or more parameters of a sample. The measurement system comprises an excitation system and a detection system. The excitation system is configured to generate combined exciting radiation comprising one- or multi-parameter modulation of multiple exciting signals of different types to be applied to at least a portion of a sample under measurements to thereby induce electron emission response of said at least portion of the sample to said combined exciting radiation. The detection system is configured for detecting the electron emission response of the at least portion of the sample and generating measured data indicative of a modulated change of an electrical state of the at least portion of the sample, thereby enabling determination of one or more parameters of the sample from the measured data.

Abstract: A method and device are presented for measuring the electrical properties of a specimen. The specimen is excited with high energy radiation to cause emission of internal charged particles from the specimen. Electrical power is supplied to a circuit, that is formed by the specimen and any added component connected to a back contact of the specimen. The electric power supply includes at least one of the following: irradiating the circuit with low energy charged particles; subjecting the circuit to an external field of the kind affecting the flux of emitted internal charged particles, and supplying a bias voltage to the back contact of the specimen. During the power supply to the specimen, at least one of the following is carried out: an electric current through the specimen is measured, and the emitted charged particles are analyzed versus their energy (using a contactless voltmeter) which provides local potential values at chemical entities of the specimen.
