188 results about "Venturo" patented technology

Venturo or Venturo House is a prefabricated house designed by Finnish architect Matti Suuronen in 1971. It is composed of fiberglass-reinforced polyester plastic, polyester-polyurethane, and acrylic glass. In the late 1960s Suuronen became known for his round-shaped Futuro House and now wanted to create a new "weekend cottage". Venturo House was a part of Suuronen's Casa Finlandia series, known as the model CF-45. Other models were CF-100/200 (1969) and CF-10 (1970), number indicating the floor area in square meters.

Apparatus for adapting air blower to perform liquid dispersal and related method

An apparatus for adapting a blower system to the dispersing of liquid material is partially housed within an extension tube of a portable blower and includes a pressurizing tub with an inlet for accepting airflow discharged by the blower. The pressurizing tube discharges into a liquid container thus increasing pressure within the container. An extraction tube exits the container and meets a Venturi tube that also accepts airflow discharge by the blower. A vacuum is created in the extraction tube through first and second apertures that allow fluid communication between the Venturi tube and the extraction tube. The vacuum created in the extraction tube extracts liquid from the liquid container and the liquid is drawn out of the extraction tube through the Venturi hole into the Venturi tube mixing with air flowing there through and discharging into airflow by-passing the spray adapter apparatus.
