A floor cleaning apparatus includes a housing having a nozzle assembly and a canister assembly. The canister assembly is pivotally connected to the nozzle assembly. Both a suction generator and dirt collection vessel are carried on the housing. The apparatus also includes a telescopic wand assembly having a first end equipped with an operator handle and a second end incorporating an airstream inlet. A wand assembly coupler is provided on the housing. The wand assembly coupler receives and holds the second end of the telescopic wand assembly. A flexible hose is connected to the first end of the telescopic wand assembly and provides fluid communication between the wand assembly and the dirt collection vessel and suction generator. The telescopic wand assembly is displaceable between a floor cleaning position wherein the second end of the wand assembly is held in the coupler and a specialty cleaning position wherein the second end is released from the coupler.

A floor cleaning appliance includes a housing having a canister assembly and a nozzle assembly. A suction generator and a dirt collection vessel are carried on the housing. A suction inlet, a rotary agitator and a bare floor wiper are carried on the nozzle assembly. In addition the floor cleaning apparatus includes a switch for slowing or interrupting drive to the rotary agitator and a displaceable height adjustment assembly. The height adjustment assembly is displaceable between one or more carpet cleaning positions and a bare floor cleaning position. The height adjustment assembly engages the switch and slows or interrupts drive to the rotary agitator when in the bare floor cleaning position.

The invention relates to a process for producing a catalyst comprising a porous support and at least one active metal, which comprises providing a porous support which has a specific BET surface area of at least 500 m2/g and is transparent to an activating radiation, applying at least one active metal precursor which comprises at least one active metal and at least one group which is bound via a ligator atom selected from among oxygen, sulfur, nitrogen, phosphorus and carbon to the active metal atom to the porous support so as to produce an adduct which comprises the porous support and the at least one active metal precursor; and illuminating the adduct with the activating radiation to convert the at least one active metal into its reduced form.
摘要:
A floor cleaning apparatus includes a housing, a suction generator having a motor and a sound cancellation generator. During operation of the apparatus the motor produces a first sound and the sound cancellation generator produces a second sound. The second sound produced by the sound cancellation generator is substantially 180 degrees out of phase with the first sound so that noise generated during operation of the floor cleaning apparatus is reduced.
