Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
167 words
An apparatus for ascertaining the presence of water in an oil, comprising a condensing chamber, a heating chamber for heating said oil, said two chambers communicating with each other, the condensing chamber being provided with a condensing surface, the condensing surface having a discharge end adapted to collect the condensate at a predetermined location by means of gravity, a measuring chamber for ascertaining the presence of a predetermined quantity of condensate in the chamber, communicating means adapted to feed the condensate collected at the discharge end of the condensing surface to the measuring chamber, the measuring chamber being provided with warning means adapted to emit a warning signal when the water in the measuring chamber reaches a predetermined quantity and a fore-chamber provided between the communicating means and the measuring chamber, the communicating means discharging into the fore-chamber, the fore-chamber being adapted to collect a predetermined quantity of condensate and provided with outlet means for delivering the quantity thus collected as a whole into the measuring chamber.
Claim 2
Independent Claim
167 words
An apparatus for ascertaining the presence of water in an oil, comprising a condensing chamber, a heating chamber for heating said oil, said two chambers communicating with each other, the condensing chamber being provided with a condensing surface, the condensing surface having a discharge end adapted to collect the condensate at a predetermined location by means of gravity, a measuring chamber for ascertaining the presence of a predetermined quantity of condensate in the chamber, communicating means adapted to feed the condensate collected at the discharge end of the condensing surface to the measuring chamber, the measuring chamber being provided with warning means adapted to emit a warning signal when the water in the measuring chamber reaches a predetermined quantity and a fore-chamber provided between the communicating means and the measuring chamber, the communicating means discharging into the fore-chamber, the fore-chamber being adapted to collect a predetermined quantity of condensate and provided with outlet means for delivering the quantity thus collected as a whole into the measuring chamber.
Claim 3
Dependent Claim
19 words
An apparatus according to claim 1, in which the condensing surface is in the form of an inverted cone.
Claim 4
Dependent Claim
26 words
An apparatus according to claim 2, in which the inverted cone at its end is provided with a downwardly extending tip projecting towards the communicating means.
Claim 5
Dependent Claim
40 words
An apparatus according to claim 1, wherein said condensing surface is in contact with a coolant-containing chamber comprising an oil chamber having an inlet for the oil to be examined and an outlet for the oil to the heating chamber.
Claim 6
Dependent Claim
32 words
An apparatus according to claim 4, in which the oil chamber is adapted to communicate with a lubricating system and dimensioned as an equalizing chamber to balance fluctuations in the oil supply.
Claim 7
Dependent Claim
89 words
An apparatus according to claim 1, wherein the measuring chamber is provided with at least two electrodes so located that they are short-circuited when the water reaches a predetermined quantity, the electrodes being located at different levels, the lowermost electrode being adapted to project into a vessel which is dimensioned so as to receive a predetermined charge of water and provided with a bottom outlet so dimensioned that the vessel can be gradually emptied through the outlet, the other electrode being located at the upper end of the vessel.
