摘要:
The instrument consists of an elastic sheet (6) borne on three sides by an elastic frame of exhaustion (1,2,6) with two ways fitted to the central exhauster, which is supplied with another or two other holds for the local suctions (11-13). The sheet is centrally held by the tooth and, owing to its elastic nature, forms a cavity for the collection of liquids. The employ of the flexible frame permits a shape adjustment and also to accede to the mouth cavity as well as not to cause any hindrance to breathing. The proceeding can be carried out by the only operator and automatically performs the liquid elimination.

Die Erfindung bezieht sich auf eine zahnärztliche Absaugeinrichtung mit einem Auffangbehälter für feste Teilchen, wie Gold oder Silberamalgam, der in einem in das Abwassernetz führenden Abwasserleitungsabschnitt syphonartig angeordnet und zum Zwecke der Entnahme der dort angesammelten Teilchen lösbar gehaltert ist. Der Auffangbehälter bildet zusammen mit einem als Verschlußdekkel ausgebildeten, siebartigen Vorfilter, das im Betrieb an anderer Stelle als der Auffangbehälter angeordnet ist, eine versandfähige Einheit.
摘要:
The method and the device provide for a sequence of steps: a first, in which heavier solid particles entrained in the waste liquid (13) are allowed to settle in a trap (1), a second in which lighter and smaller particles are filtered out, and a further step of reducing infinitely small ionic particles dissolved in the liquid by inducing electrolysis with a metal less noble than that contained in the ions, i.e. of higher electropositive potential, such that dissolved matter is deposited onto the electrode (5).
摘要:
A moisture trap is disclosed of the type, used in fluid suction equipment for dentistry in particular, which comprises a negative pressure intake (1) consisting of a venturi (2) that draws in fluid and delivers it into a vertical separation chamber (3) having an outlet (6) at bottom via which liquids are discharged, and a outlet (7) uppermost via which air is exhausted. A trap according to the invention has a separator device, located between the chamber fluid inlet (9) and the air outlet (7), embodied as a column of components arranged in such a way as to create a tortuous passage through the separation chamber (3) in which the direction of the stream of fluid is changed several times.
