Abstract: A method for producing a screw foundation for securing elements in the ground, provides a cylindrical tube as an initial form and a conical front portion tapering to an insertion tip is then molded on to the cylindrical tube using a non-cutting process, the front portion being provided at least in some regions with a thread-like contour for screwing into the ground. An inner contour for a screwing tool is formed integrally in a rear end of the tube by flow forming, and the front portion and the thread-like contour are formed exclusively by flow forming.

Abstract: A method for chipless production of a rotationally symmetrical body from a circular sheet metal blank shapes the circular sheet metal blank into a pot-shaped body by pressing or pressure rolling around an inner mandrel, and a hub-shaped projection protruding outward from the base of the pot-shaped body is molded on by pressing around a central projection. The circular sheet metal blank is clamped only in the radial inner region of the blank in the axial direction between the inner mandrel and at least one projection during the shaping process.

Abstract: The invention relates to a method and a device for producing elementary oxygen or for increasing the concentration thereof in the inhaled air of a user. According to the invention, water is split into hydrogen and elementary oxygen by means of electrical energy (electrolysis), the elementary oxygen is mixed with the inhaled air, and the hydrogen is mixed with the surrounding air in order to be converted back into water (fuel reaction). The splitting of the water into hydrogen and elementary oxygen and the conversion of the hydrogen and surrounding air into water take place simultaneously and continuously, forming a reaction circuit, and are coupled to each other, the electrical energy produced during the conversion being used to reduce the energy demand for the splitting.

Abstract: A The invention relates to a nasal breathing mask having a mask part (1) and a mask-holding part (2) which at the upper end is connected to a tube (3), a forehead plate (10), which is connected to a forehead-plate mount (9), being axially adjustable on the elongate tube (3) by means of a latching/clamping connection.

Abstract: The invention relates to a nasal breathing mask having a mask part (1) and a mask-holding part (2), which at the top end is connected to an elongate tube (3) which in turn is connected to a hose connection for a breathing hose and on which a forehead plate (10), connected to a forehead-plate mount (11), is axially adjustable, a region (9) which is more flexible than the rest of the tube (3) being designed and arranged along the path of the tube (3) in such a way that the mask part can be moved toward the user with respect to the forehead-plate mount (11), in order to allow adjustment as a function of the patient's anatomy.

Abstract: The invention relates to a nasal breathing mask and a mask cushion for a nasal breathing mask. The nasal breathing mask comprises a mask cushion and a mask-holding part, which is connected to a hose connection for a breathing hose, and at least one strap for positioning the breathing mask on the face, in particular on the nose, of a user. Together with the mask part, the mask cushion for the nasal breathing mask forms an inner space for accommodating at least the nose of the user. The mask cushion consists of flexible material with a sealing lip, the sealing lip, when the breathing mask is being used, bearing in a sealed manner on the face of the user by means of a part of its outer surface and, in the process, being deformed. In the bearing part, the sealing lip delimits an opening to the inner space by means of an edge and may have a thickened section.

Abstract: The invention relates to a method and a device for determination of functional residual capacity (FRC) by introduction of helium or another inert gas mixture. According to the invention, a measurement apparatus measures the density of the gas mixture upon inspiration and upon expiration at the mouthpiece of a tube or at a mask during forced ventilation of a patient over a plurality of respiratory cycles. The FRC is determined from the difference in the gas concentrations.

Abstract: A medicament nebulizer in which a liquid medicament is drawn through capillary flow along a bell shaped path to an annular medicament orifice. Pressurized atomization air is discharged from an orifice and is directed against a deflector which causes the air to flow with a swirling turbulence over one or more medicament orifices. The atomization air aspirates medicament from the medicament orifice and atomizes the medicament. The turbulent swirling flow of the atomization air decreases the average size of the droplets in the resulting aerosol. The flow path of the aerosol through an aerosol chamber to a mouthpiece may rapidly change directions to facilitate condensation of any large droplets in the aerosol. Alternately, a swirling or spiral flow direction may be imparted to the aerosol as it passes through the aerosol chamber to cause any larger droplets to contact and condense on the walls of the chamber.

Abstract: A hand-held aerosol dispenser for a therapeutic liquid for inhalation therapy with an atomizer nozzle disposed in a housing for the delivery of compressed air is provided with a detachable reservoir for the liquid. The liquid is aspirated by the Venturi principle through a duct discharging in the region of the atomizer nozzle and atomized into very fine particles using a baffle element opposite the atomizing nozzle. The reservoir, which corresponds in its dimensions to the dimensions of the housing, is detachably accommodated in the lower part of the housing. The duct, discharging in the region of the atomizing nozzle, is elongated downward by a suction nozzle, which passes through an upper opening of the reservoir into the vicinity of the bottom of the reservoir. The reservoir contains sterile water or a mixture of sterile water and drug.
