Insulating Materials Patents (Class 220/DIG9)
  • Patent number: 5759624
    Abstract: A method of insulating a substrate or a portion thereof by depositing a syntactic foam by a spraying, dipping or a variety of printing processes. The foam comprises void containing particles in expanded form, unexpanded form, or a mixture of these. The deposited foam is dried to remove solvents and cured to strengthen the binder which restrains the microspheres. Heating may also expand the unexpanded microspheres. A tie coat may be applied to promote adhesion between the substrate and the insulating syntactic foam. Multiple layers of the syntactic foam may be applied to increase the thickness of the resultant layer for providing a controlled amount of increased insulation.

  • Patent number: 5706969
    Abstract: The present invention relates to an insulated container used for example as a cooler box, a thermos flask or an insulated lunch box, a suitable insulating material for such a container and a method for its manufacture. The insulated container of the present invention is made with an insulating layer between inner and outer walls of a double walled container with the inner and outer walls joined together as one, and has an insulating material, made by filling a bag with a low thermal conductivity gas comprising at least one of gases such as Xenon, Krypton and Argon, disposed between the inner and outer walls. The method of manufacturing the insulated container involves the steps of inserting a bag into the space of the double walled container, filling the bag inserted into the space with a low thermal conductivity gas, and then sealing the bag.

  • Patent number: 5509248
    Abstract: A boxlike body (10) with a rear wall (12) and four side walls (14) is brought into a fixture (34) with the free edges (22) of the side walls pointing downwards. The walls of the body are filled with insulating powder by blowing the powder into the rear wall (12) by gaseous medium of a first pressure. The powder is then packed by gaseous medium of a second pressure, which is higher than the first pressure, being let into the rear wall. During the filling and packing the media is let out via a filter element (24) arranged at the free edges (22) of the side walls. After the filling and packing the media is evacuated from the walls through the filter element (24). The body can then be used as a so-called vacuum insulation in a refrigerator or freezer.

  • Patent number: 5386706
    Abstract: A low heat-leak cryogenic system comprising a cryogenic fluid, a first lamina having an external side facing toward and exposed directly to, or indirectly to, the cryogenic fluid and an internal side facing away from the cryogenic fluid; a second lamina spaced apart from the first lamina, and at least one block or layer of coherent aerogel extending from the first lamina to the second lamina. In another version, the aerogel is in a gaseous environment having a pressure not greater than 250,000 micrometers of mercury. In another version, at least one of the lamina is flexible so as to at least partially transmit an external load, such as that imposed by the atmosphere, to the coherent aerogel, and the coherent+ aerogel is capable of at least partially transmitting a load imposed on it from one lamina to the other.

  • Patent number: 5251473
    Abstract: Inner and outer welded steel protective tanks are separated by a space containing a granular insulating material such as perlite preventing excessive heating of fuel in a storage space in the inner tank, even when there is a fire at the site. The inner tank is subdivided into portions by a partition defining a storage space and an overfill containment space receiving overflow from the storage space portion, with a sensor detecting overflow. The overflow containment space is also arranged to collect separated fuel when the tank system is used with a vapor recovery system. The granular insulating material acts as an explosion suppressant by dissipating heat and fuel vapors which may be present in the insulation space as a result of leakage from the inner tank.

  • Patent number: 4704875
    Abstract: A beverage cooler comprises a housing member of generally rectangular configuration. The housing includes a bottom horizontal wall and a plurality of generally vertical side and end walls which are integrally formed with the bottom horizontal wall to define an enclosure having a top opening. Coolant and consumable items normally are inserted in the cooler through the top opening and a cover member is positioned over the vertical walls to form an enclosed container. Sleeve numbers extend through at least one on the vertical wall members and are integral therewith. The sleeve members form an integral outer surface with the wall members for preventing cool air from leaking from the interior of the cooler. The sleeve members enable beverage containers to be inserted therein so that the containers can be cooled by being adjacent the cool air in the interior of the beverage cooler.

  • Patent number: 4499997
    Abstract: An improved tote box especially adapted for use within an automated storage and retrieval system is provided with a bumper rim a short distance from the tote bottom to reduce the moment arm created when the box engages another box or the like. Stacking stops are integrated with the bumper rim to provide additional strength, and the stops circumscribe side drains to allow fluid to be drained without flowing into a lower box in a stack. A divider grid is provided and includes intersecting crosswise and lengthwise divider plates, each Z-shaped and each having mounting slots in one edge and notches in the other. When the plates are mated by seating the slot of a lengthwise plate in the slot of a crosswise plate, the opposing bosses at the mouth of each slot of each plate seat in the notch of an intersecting plate. Tabs on each end of each plate seat in slots in the tote box walls and a ramp overlying the notch restrains the divider plate tab to secure the grid in the tote box.

  • Patent number: 3951730
    Abstract: The present invention relates to a compressible construction to be used as isolation or as packing material, comprising equidistant bellow-like compressible layers, which are interconnected by a zigzag folded strip which is alternately connected to the layers. Short projecting parts are positioned between the zigzag strip and the layers to add support. In the folded compressed condition when not in use, the construction has a very small volume, while in the expanded condition it is able to act as a heat insulator and pressure, shock and vibration resistor. Important features of this construction are its small volume as it can be compressed when not in use, its ability to isolate from heat, to resist pressure, shocks and vibrations.
