Title: Humidifier with detachable fan assembly
Inventor: STANEK TERRENCE L
IPC: F24F13/20
Filed: 1999-11-30
Abstract: A humidifier is disclosed. The humidifier includes a housing, in which a moisture source resides, and a fan assembly connected to the housing for moving dry air into the housing, through the water source, wherefrom the dry air picks up moisture, and finally out of the humidifier. The fan assembly is detachably connected to the housing and has a stand so that the fan assembly can be in an upright position when detached from the humidifier housing and function as a stand-alone fan. The humidifier housing has multiple openings for accommodating the power cord of the fan assembly. In operation, the fan assembly is attached to the humidifier housing to move air into the humidifier housing to pick up moisture from the source of water, and subsequently out of the humidifier housing to circulate humidified air; the fan assembly is then detached from the humidifier housing and operated to circulate unhumidified air. The power cord may be placed through any one of the multiple openings on the humidifier housing so that the humidifier may be positioned in a way that is the most space-saving, convenient and/or aesthetically pleasing.

Abstract: The invention relates to a method for manufacturing a composite element comprising at least one wooden layer which is bound to a concrete or mortar layer, as well as to a composite element manufactured accordingly. In order to provide this composite element with a high load carrying capacity, which is the result of the concrete or mortar layer adhering onto the whole surface of the wooden layer, an adhesive (16) with a paste consistency is applied so that the adhesive coats the surface and forms an adhesive layer. Then, fresh hydraulic concrete or fresh hydraulic mortar is spread onto the adhesive layer (16) and is distributed over this layer in order to coat the surface and form the concrete or mortar layer (14). The adhesive layer (16) and the concrete or mortar layer (14) are caused to set during a common transient setting phase to produce an inter-layer binding over a large surface.
