Abstract: An apparatus for treating burn and scald wounds and localized disorders on portions of the human body which involves rapid cooling thereof by spraying a liquid from a first hand-held container onto the human body portion to be treated to form thereon a film of the liquid. Thereafter, a refrigerant is sprayed onto the film of liquid from a second hand-held container, the refrigerant being at a temperature low enough and at a flow rate high enough to freeze a substantial portion of the film of liquid. The human body portion is thereby rapidly cooled by heat absorbed by the frozen film.

Abstract: This device includes a water container (1) with a pump (8), an operating button (4) and a spray nozzle (5). A second container (2) holds a refrigerant which is released through a second spray nozzle (7) by pressing on a second button (24). As a first aid measure, a film of water is first sprayed on the burn wound and then is frozen by means of the refrigerant. In this way, an immediate and drastic reduction in pain is achieved. Since the heat is rapidly and effectively dissipated from the injured tissue, substantially fewer burn toxins are formed so the healing prospects are greatly improved. The subsequent scar tissue formation on the wound is much better from a cosmetic standpoint. This device may be constructed in a small and handy form and therefore can be kept ready to use wherever there is the risk of burn and scald wounds.

Abstract: The insulated outer coating of walls of building structures includes a cured foamed insulation material applied in a flowable state and an outer plaster means. Metal plates forming the moulding form for the injected foamed insulation material are connected by means of threaded bolts with the wall of the building structure, whereby a space is defined between the outer surface of said wall and the inner surface of each metal plate. A flowable insulation material containing urea-formaldehyde is injected into this space and cured therein. Each metal plate comprises protrusions and perforations. The perforations extend through the protrusions as well as through the metal plate. The plaster material applied on the outer face of the metal plates penetrates in its flowable state the penetrations and when cured in anchored by means of the protrusions and the penetrations.

Abstract: A method of after-foaming a mixture containing a foam and a resin solution. The foam component is brought into contact with the resin solution by means of a suction action. The after-foaming is produced due to said suction action and by superfluous air present.

Abstract: A heating system with a thermal pump including an evaporator section consisting of a piping network buried in the ground. The piping network is shielded by a translucent screen arranged above the ground such to prevent a heat loss of the ground and to form a space for heat storage between screen and ground.
