1. Apparatus for maintaining a concentration level of a gaseous material within gas filled surroundings, comprising:
- a first container containing a gas;
a second container containing said gaseous material in the form of a liquid;
a sensor which senses the concentration of the gaseous material within the surroundings and generates signals responsive to the concentration; and
an automatic dispenser mounted on the first container of the gas which dispenses the gas in response to the signals from the sensor, into fluid driving engagement with the liquid in said second container, thereby to cause dispensing of said liquid into said surroundings, wherein the apparatus operates substantially independently of any wired or fluid communication with elements other than the sensor, containers and dispenser.

5. A method of maintaining a concentration level of a gaseous material within gas filled surroundings, the method comprising:
-
providing a first container containing a gas and a second container containing said gaseous material in the form of a liquid;
providing a sensor, sensing the concentration of the gaseous material within the surroundings and generating signals responsive to the concentration; and
mounting an automatic dispenser on the first container of the gas which dispenses the gas in response to the signals from the sensor into fluid driving engagement with the liquid in said second container, thereby to cause dispensing of said liquid into said surroundings;
wherein the sensing and the mounting operate substantially independently of any wired or fluid communication with elements other than the sensor, containers and dispenser. - View Dependent Claims (6, 7, 8, 9, 10)
