    摘要： A register box for HVAC installations has a body with a plurality of side panels arranged in a generally rectangular or square configuration and a wall extending across the rectangular configuration, a duct opening through the wall so as to communicate with an interior of the body, and an expandable foam polymeric material affixed to an inner side of the side panels. The wall has a surface extending from the opening of the duct to the side panels. The expandable foam polymeric material is affixed to the surface of the wall. The expandable polymeric material is polyurethane.

    摘要： A continuously moving foam spray nozzle which supplies liquid plastic such as polyurethane moves in a path to define and create a solid structure which solidifies immediately as the nozzles moves away and the result can be a curved solid building structure similar to a conventional "Quonset hut" made from solid plastic or can be wall structures of different shapes. The foaming spray nozzle is carried on a guide frame which moves along a predetermined track and in the case of curved structures like a "Quonset hut" the foam nozzle moves in an arch from one side to the other and at the same time is moving lineally on the track to create a continuous curved shell of whatever length is desired. (Nozzles may be mounted facing each other in opposition to coat a shell formed there between by the foam which is applied from other means.) In another form, simultaneously with the creation of plastic structure a covering of sheet plastic or other similar material is supplied from rolls carried with the nozzle, whereby the exterior surfaces both outside and inside may be simultaneously covered with sheet plastic or other similar material which adheres to the foam. With the nozzle operating from side to side and simultaneously moving lineally, wall panels may be created continuously and simultaneous covered with a skin of plastic or other similar material. According to the method of the present invention, the material used must be self-supporting in atmosphere (e.g. plastic foam) so as to remain in place and resist dripping by gravity until it has solidified sufficiently to form a solid structure. The method is that of continuously supplying a foam material and continuously moving said supply in a pre-determined pattern to create a three-dimensional structure by moving said supply both lineally and in a direction either straight or curved transverse thereto.

    摘要： Apparatus for producing a porous plastic molded product of uniform, predictable porosity throughout. A fluidized airstream of moldable plastic powder is formed. Water may be injected into said fluidized powder airstream for maintaining said powder in a uniform, fluidized dispersion. The moisturized, fluidized, powder airstream is injected into a cavity of a closed mold to fill said mold cavity with said powder. The mold is maintained at a temperature and for a time sufficient to at least partially fuse said powder particles together without melting said particles, thereby to form a porous, plastic molded product. The mold is partially separated for cooling the product which is then discharged from the mold. The product may be further cured by heating the molded product in an oven at a temperature and for a time sufficient to cure said molded product without melting said plastic or glazing said product.

    摘要： An improvement in the generation of foam from a mixture of foam-forming material in a structure having a preferred configuration. Conveying means are used to convey the structure along a horizontal path. A plurality of foam gun heads are mounted in spaced relationship to each other over and transverse to said horizontal path. Each foam gun head includes a foam dispensing outlet and valve means for controlling the discharges of the foam-forming materials therefrom. First, sensing means are provided upstream of the foam dispensing outlets for sensing the passage of the structure thereby. A plurality of second sensing means are positioned upstream of the foam dispensing outlets in spaced relationship to each other in a direction transverse to the horizontal path, each one of the second sensing means being associated with one foam gun head for sensing the presence of the structure in a vertical direction. The valve means in a foam gun head is opened in response to the first sensing means sensing the structure and its associated second sensing means also sensing the structure. The valve means of a given foam gun head is closed in response to its associated second sensing means detecting the absence of structure.
