Abstract: A container for water. The container has walls and a base and a magnet located adjacent the base of the container. The magnet is positioned to be below the level of water in the container when water is present in the container. The invention find particular application in a bubble humidifier to humidify gas bubbled through water contained in the bubble humidifier prior to the gas passing to a patient.

Abstract: An illuminated display to be received on a perforate board to receive packages. There is a support of an electrically conducting material to be received in perforations in the board. The support can be connected to a source of electricity and an illuminator is attached to the support in electrical contact with the source of electricity. A package is carried by the support. Wares are attached to the package. An illuminated display having a base to be received on a pair of electrically conducting members is also disclosed. A pair of contacts, one to make electrical contact with each electrically conducting member are provided and a circuit is formed on the base. An illuminator on the base is in electrical contact with the circuit. Completion of the circuit by the pair of contacts lights the illuminator. A display having a support card to be received on a pair of electrical conductors is disclosed. Separate contacts on the card to make contact one with each conductor.

Abstract: An attachment for a flexible tape measure. The tape measure includes a tape having calibrations marked on it. The attachment has a bracket slidably received with a frictional fit on the tape. The fit requires application of a slight force to move the bracket. A housing is formed in the bracket, and a magnet is received in the housing and positioned to align with an end of the tape, parallel with the calibration marks. The attachment allows multiple uses of the tape measure, for example, as a level and a square.
