Abstract: A car wash in which sponge rollers are used and are yieldingly held against the top and two sides of the vehicle and are positioned in the car wash after the vehicle has been washed. The sponge rollers are compressed against the top and sides of the vehicle and will absorb the water film remaining on the vehicle. A vacuum shoe contacts each sponge roller and vacuum is used for removing any fluid in the sponge roller as the cylindrical surface of the roller moves under the shoe. The fluid withdrawn from the roller is conveyed to the sewer.

Abstract: A portable apparatus for blowing a chemically treated cellulose insulating material into an attic, wall cavity or wet spraying the material against a surface for insulating it. The apparatus breaks the cellulose material into small particles and, after fluffing the material, the apparatus meters and feeds the material under pressure through a hose and out through a nozzle where an operator can point the nozzle for directing the material to any desired area. Three different nozzles are used: one for attic insulation; a second for filling wall cavities; and a third for wet spraying the material against a surface for causing the material to adhere to the surface.
