  • Patent number: 4365441
    Abstract: A thermal Shutter Shield (R) device comprised of an outer periphery support frame which supports an outer glass area means and an inner glass area means in a parallel mode, the glass area means are normally called windows, glass sliding doors or glass walls including a glass peripheral frame and a glass panel installed therein, the device is further comprised of a Shutter Shield unit spaced between the glass areas, having one or more sets of horizontal and parallel extending tracks which are vertically spaced a distance at least equal to the height dimension of the glass area units, the tracks extend parallel to the plane of the glass area and beyond at least one side of the side edges of the glass area unit, a laminate insulative Shutter Shield is mounted in the track for movement between positions at the side of the glass area unit and in front thereof to block off the entirety of the glass area, the laminate insulative shield includes a frame movably supported on the track and has an imperforate surface la

  • Patent number: 4344265
    Abstract: This invention relates to energy conserving structural elements, commonly called window or door frames with outer framing being adapted to be installed in building wall rough openings, said framing has a strip of compressible expandable thermal insulation fastened in a recess in said framing and an enveloping means maintains said thermal insulation in a compressed state until said structural element is installed in said building wall, said enveloping means is of tearable material that can be rendered inoperative allowing said thermal insulation to expand and fill said air gap, reducing heat transfer either direction through said air gap.This invention relates to all objects constructed to be inserted into other objects creating an air gap that should be sealed and thermally insulated.

  • Patent number: 4337603
    Abstract: A bushing formed of insulation that can be installed in holes drilled in wood framing components, used to construct a building, such as a dwelling, these holes are drilled so plumbing pipes & electrical wiring can be installed in said framing components.Purpose of this invention is to close off & insulate these holes before the articles are installed, or after they are installed, either method would greatly reduce infiltration & heat transfer through these necessary drilled holes, reducing the energy usage in said building, helping our Countries energy conservation program.

  • Patent number: 4326360
    Abstract: A thermal shutter device with vertical travel for use in combination with a window unit comprising a window frame & glass panels mounted in the window frame which is installed in a building outer periphery walls such as a dwelling, this device which is a thermal insulation construction comprising at least two thermal shutters with vertical travel & means to seal said thermal shutter device to create a sealed chamber between shutter device & window construction, the shutters can be of laminate construction with rigid insulation mounted in vertical track allowing shutters to slide up & down on compressible insulation slide means, when in closed mode they will greatly reduce heat transfer or infiltration either direction through said window construction, therefore reducing energy used to heat or cool said building, therefore helping our countries energy conservation program.

  • Patent number: 4294038
    Abstract: A solar panel device for use in combination with a window unit including a window frame and glass panels mounted in the window frame. The device is comprised of a shutter unit having one or more sets of horizontally and parallel extending tracks which are vertically spaced a distance at least equal to the height dimension of the window unit. The tracks extend parallel to the plane of the glass panel and beyond at least one of the side edges of the window unit. A laminate insulative shield is mounted in the track for movement between positions at the side of the window unit and in front thereof to block off the entirety of the glass panel. The laminate insulative shield includes a frame movably supported on the track and has an imperforate surface layer and an insulation material layer mounted side-by-side in the frame. The imperforate surface provides a rigidifying support for the rather fragile insulation material.

  • Patent number: 4254999
    Abstract: The purpose of this invention is to standardize die shoes, which are the upper and lower portions of a fabrication die that supports the working portion of a die and punch. They are also used to mount the die into the stamping press. Standardization would reduce the die shoes into standard re-usable components which could be used year after year, which would reduce waste of material, plus allow interchangability between dies. Also, standardization will allow die shoes that can be changed to a larger shut height to suit larger die construction or larger presses. This feature will eliminate extra plates being added to dies when it is necessary to change the die to a larger press, which will improve safety. Standardization of die shoes amounts to breaking down the die shoes as commonly designed into standard components which can be reused and interchanged from die to die, press to press, year after year.

  • Patent number: 4204373
    Abstract: A method of providing thermal insulation in relatively small spaces, such as the spaces between window and door frames and the structural members forming the rough openings therefor, comprises use of a prefabricated compressed-insulation tape, which may be secured at the factory to the outer periphery of the window or door frame, or to the inner periphery of the rough opening on the building site, the tape comprising a strip of any suitable compressible insulation material, such as spun glass or polyurethane, for example, retained in a compressed state by means such as a paper or plastic envelope, the envelope having at least one rip cord, whereby when the rip cord is pulled after installation of the window or door frame to rip the envelope longitudinally off the tape, the compressed insulation expands to fill the air gap space between the frame and the rough opening structure to provide thermal insulation therefor.
