Abstract: An ice bath comprising a container, a refrigeration coil for causing liquid in the container to turn to ice, a pipe for carrying liquid to be cooled by the ice bath for dispense and a plurality of conductive probes for measuring ice thickness, wherein the conductive probes are provided between at least part of the refrigeration coil and the pipe for carrying liquid to be dispensed such that a first one of the conductive probes is provided closer to the refrigeration coil at least two other conductive probes, and thereby the at least two other conductive probes are provided closer to the piping than the first conductive probe, and wherein the second and third probes are equidistant from the refrigeration coil, the ice bath further comprising means for measuring the conductance between the first probe and the second probe, the first probe and the third probe, and the second probe and the third probe.

Abstract: Air treatment apparatus including means for causing ultraviolet radiation to be applied to fluid or moisture which is to be discharged from the apparatus.

Abstract: Water purification apparatus, comprising an elongate UV source and a conduit for water to be purified formed of a UV transmissive material, wherein the conduit has an inlet and an outlet and positioned so that part of it is wrapped around at least part of the UV source thereby to sterilize water within the conduit, further comprising reflective means for UV radiation to be reflected onto one or more parts of the conduit which extends beyond the part which is wrapped around the UV source.
