Abstract: A circulating bath (10) including a heater (18) configured to heat a fluid (34) in a reservoir (22). The heater (18) is configured to be operatively connected to a source of power (50) by a control circuit (39) operatively coupled to the heater (18). First and second fluid level sensors (14) (16) are operatively coupled to the control circuit (39), and provide signals indicative of a low fluid condition in the reservoir (22). The control circuit (39) is configured to receive the signals from the fluid level sensors (14) (16), and disconnect the heater (18) from the source of power (50) in response to receiving a signal from either of the first and second fluid level sensors (14), (16) indicative of a low fluid condition.

Abstract: A pump casing has a metallic band that defines a sidewall of the pump casing and having at least one tab projecting from a surface thereof or at least one opening. The pump casing also has first and second plates disposed opposite one another, with the metallic band being disposed there between, and with the first and second plates and the metallic band jointly defining a chamber of the pump casing. At least one of the first or second plates includes at least one tab or at least one opening respectively cooperating with the at least one opening or the at least one tab of the metallic band so as to retain a formed shape of the metallic band in the pump. The at least one opening may, for example, be a slot in the at least one of the first or second plates.

Abstract: Various components may be used to construct an artificial anchor point having a number of support legs. The support legs may articulate with respect to a plate assembly, may slide through a leg holder, may be telescopic, and may be configurable to conform to a variety of terrains. The support legs may be positionable horizontally with respect to a plate assembly for spanning a gap.
