Abstract: In order to improve the flame protection effect without substantially impairing the mechanical properties of the articles covered with the flame protection agent, the flame protection agent is provided with a compound in a proportion by weight of 7.5 to 30% which contains at least one sulfo group or sulfonium ion. This compound is preferably a water soluble ammonium salt. As binder there is used an aqueous solution or aqueous dispersion of an organic material, particularly of an acrylate or of a polymer or copolymer having a base of acrylic acid ester. It is particularly advantageous if substantially open-cell polyurethane foam having a base of polyether is impregnated with such a flame protection agent which contains an ammonium salt of an aminosulfonic acid in a proportion of about 12%. Polyurethane foams impregnated in this manner are particularly well suited for use in cushionings of articles or in premises for which class B1 fire protection is required.

Abstract: Fine grain or fibrous solid active particles are immobilized in an areal or flat, flexible stratified body. The active particles serve for treating a liquid or gaseous medium circulating between the stratified body and the surroundings. The treatment, among other things, encompasses the sorption of substances, if desired, followed by desorption for regenerating the active particles, the emission of substances, the ion exchange and the catalysts of chemical reactions. The active substances or particles are enclosed between a base or substratum layer and a fiber-containing cover layer. Both layers are held together by means of holding fibers which are densely distributed over the entire surface and simultaneously anchored in both layers, whereby at the same time there are also immobilized the active particles. According to a preferred method the holding fibers are removed from the cover layer by fiber-orienting needles.

Abstract: A press, carried by a first table and having punch and die components, receives a rectangular filler sheet and forms a lateral accordian fold sheet. The accordian fold sheet is lifted from the press by transfer means and placed upon an envelope sheet overlaying a second table. Hinged panels carried by the second table fold the envelope sheet over the accordian fold sheet, forming a rigid compartmentalized panel having an opening along a longitudinal edge. The second table, with the opening upright, moves to a position under a receptacle from which granular loose fill material is entered into the compartments through the opening. Subsequently, flaps extending along the panels move to further fold the envelope sheet and close the opening.

Abstract: A method of preparing cells for the purpose of enabling one fluid to be affected by another fluid via thin membranes of inorganic artificial fibres, which membranes are corrugated all over or in part and caused to bear upon each other along discrete lines of contact so as to form through passages or compartments for the fluids. The cell is constructed of membranes of artificial fibres which have a filament diameter of at least 3 and at most 20 micrometers and are elastic. The fibres are loosely matted so that when the spaces between the fibres in the assembled cell have been filled with a fine powder which is bound with an inorganic binder the powder forms a load-bearing layer which is cohesive throughout the surface extension of the membrane and through its cross-section and in which the fibres act as reinforcement.

Abstract: An elastomeric enclosure is initially inflated to a desired pressure by a gas having large molecules incapable of diffusing outwardly from the enclosure, except at a relatively slow rate. When the enclosure is surrounded by ambient air at atmospheric pressure, such air passes into the enclosures by reverse diffusion, thus extracting energy from the ambient sea of air to progressively increase the total pressure in the enclosure to a substantial extent over a period of several months, the pressure then decreasing very slowly over an extended period to its initial inflation pressure, such extended period being as much as about two years or more. This added energy may be used to perform useful work or used in various pneumatic devices to achieve essentially permanent inflation.

Abstract: A composite material is formed with a porous core obtained by randomly folding or crumpling metal foils or filaments and has a coating adapted to strengthen the final product, of an adhering synthetic resinous material. Preferably, the core material is made more dense at the surface than at the interior as by hammering, pressing, striking, rolling, etc. To permit greater penetration of the resinous coating into the core, the core may be slit, punched or bored. The surface of the coating material may be further treated by fillers, painting, coating, vapor deposition, etc.

Abstract: The invention introduces a cellular air bag insulator and its uses in insulating a house window, a house door, a house wall and process equipment, such as an evaporator, a refrigerator and a distillation column. A cellular air bag insulator is a light weight insulator and comprises an outer enclosed bag and an expansible and collapsible multicompartment core such as a honeycomb structure joined to the outer bag. It can easily be inflated and deflated. When it is inflated, multitude of horizontal air compartments in multilayers are formed in the bag to provide a high resistance to heat transfer through the bag by reducing convective flow of air within the bag and by requiring the heat to pass through the multilayers of air compartments. When it is deflated, it occupies a rather small volume and can be rolled up or folded into a compact form that is convenient to handle and store.

Abstract: A fiber-reinforced plastic structure is obtained by weaving fibers in one direction about one or more spacing members located angularly to the fibers. The fibers may be either warp or woof stands, the spacing member serving as woof when the fibers from warp strands, and as warp when the fibers form woof strands. The removal of the spacing member leaves relatively large open channels forming, in effect, a multi-wall hollow structure. The resultant structure may be partially or completely treated with a plastic resin system prior to or after the removal of some or all of the members. The solidified resin reinforced structure may be filled with a foam-in-place plastic, and it may be stacked in layers to provide additional thickness with reinforcing fibers running in different directions for additional strength. Some fibers may extend from one ply into an adjacent ply or into more remote plies.

Abstract: A multicelled structure which may be used as a body support or other cushioning device has inflatable cells against which a supported or cushioned body bears. The structure is formed from a flexible material on mandrels which have a fluted or other shaped configuration and spaced apart. This prevents the material which is in a soft or uncured condition from bridging adjacent cells during the forming operation. The fluting or shape on the resulting cells is configured to enable the side walls of adjacent cells to closely approach or contact each other when the cells are expanded by internal fluid pressure so that the end walls of the cells form a generally continuous surface.
