Abstract: A breathing mask with a fixed, curved mask body and with a mask edge extending around the mask body and adapted to the shape of the face for attaching a sealing edge sealing the mask body against the face and with a supply opening located in the mouth area of the mask body. The mask body provides low-distortion vision along with the largest possible useful field of vision. To accomplish this task, the curvature in azimuthal section planes (5, 6, 7) of the mask body (1) is designed to decrease continuously in the corresponding section plane toward the mask edge (2), starting from a meridian symmetry axis (4) of the mask body; that the azimuthal curvature on the meridian symmetry axis (4) also decreases monotonically, starting from the mouth area (8); and that the meridian curvature of the mask body 1 along the symmetry axis (4) is essentially uniform.

Abstract: The present invention pertains to a radar device with synthetic aperture based on rotating antennae (ROSAR principle), preferably for helicopters, which operates in the millimeter-wave range and is used mainly as an obstacle radar, wherein the full synthetic aperture length can be reached already within very short distances due to the arrangement of the antennae on a turnstile. Exemplary embodiments, calculations and representations are shown and explained.
Abstract: Apparatus for automatically stretching a tubular knitted article slipped on a support shape, comprising:--a device for picking up a limited portion of the article (4) fabric in correspondence of a side edge of the shape (5), holding said article and finally releasing it by way of an elastic, flat-nose, normally closed gripper (1);--a pneumatic cylinder (2) having a horizontal axis and its rod fixed to the base of said gripper (1) to allow it to be moved from and to the shape (5); --a cam (3) having double straight profile to operate the activation, that is, the opening and respectively the closing of said gripper (1) in cooperation with two pivots each of which is idly fitted into a corresponding jaw of the gripper (1) so as to result sideway projecting therefrom and thus engaging a relevant profile of the cam (3) during the activation of the gripper (1): the cam (3) being interposed between the gripper (1) activating cylinder (2) and the stocking (4) supporting shape (5);--an abutment element (6) interposed

Abstract: Thermal forming of objects made from plastic material if performed by machine which has first, second and third sectors. The first sector includes structure for unrolling a coil of plastic sheet material. The second sector receives and transports the plastic sheet from the first sector and also heats the plastic sheet as it is moved through the second sector. In the third sector, there is a rotating die which has a plurality of die faces. Each of the die faces is an object form. A first stage of the rotating die receives the heated plastic sheet from the second sector and deforms the heated plastic sheet around the object form to create the object shape. A second stage of the third sector cools the deformed plastic and removes the object from the die faces.
Abstract: 3-.alpha., 7-.alpha.-dihydroxy-12-keto-5-.beta.-cholanic acid is microbially produced from cholic acid by alkalophilic Bacillus strains. The preferred strains are Bacillus sp. FERM BP-3394 and Bacillus sp. FERM BP-3397.
Abstract: The present invention pertains to a window shade with a winding shaft (1), at one end of which a drive assembly is provided, and both ends of which are rotatably mounted in stationarily mounted brackets (8). So as to use identical brackets to mount the winding shaft at both ends at the end of the winding shaft (1) located opposite the drive assembly, a mount with a shaft journal (4) mounted freely rotatably in a housing (3) on the winding shaft is provided, which shaft journal (4) has, at an end projecting from the housing (3), a receiving slot of polygonal cross section, which is open on one side, for a support pin (7) of a corresponding cross section, which is provided on the bracket (8), as well as an elastically deformable locking element (5), which holds the support pin securely in the receiving slot.
Abstract: A process for preparing wear-resistant edges (3) on turbine blades, e.g., in the area of the upper leading edge of the blade and on the cover sheet, preferably for steam turbines made of chromium steels and/or titanium-based alloys includes preparing a recess (2) on the corresponding area of the blade (1), preferably by forging or machining, prior to the application of the edge protection (3), applying a powder layer in the corresponding area by low-pressure plasma spraying or according to the encapsulation technique, and subsequently compacting the powder layer by hot isostatic pressing (HIP), and the diffuse binding to the base material of the blade is thus achieved.
Abstract: An anticellulitis massaging device comprising a plurality of massaging elements or fingers (11) located within a body member or casing (10) and susceptible of axial percussion movements and oscillating and/or rotating movements, which are controlled by a motor assembly (12,12a) and via cam actuating means (15a,25a).
Abstract: Device for prolonging the effective usage time (service life), arrangement and process for minimizing temperature effects in any ion-selective polymer membrane electrode measuring chain (ISPE measuring chain), wherein one solution or both solutions directly adjoining the polymer membrane (outer measuring solution and inner potential drain solution) are saturated or supersaturated with the compounds which normally tend to bleed out; and wherein the isotherm intersection of an ion-selective measuring chain with redox drain elements is optimally located in the middle of the measuring range such that this middle is located at ca. 0 mV.The device may be used for monitoring of groundwater with opposite changes in the concentrations of nitrate and ammonium, evaluated in a special device, with electronic data processing and intermediate data storage (in RAM pack) at the site of the measurement and data polling as needed to a central unit by telemetry.
Abstract: The present invention pertains to a window shade drive with an automatically acting coupling, which has friction surfaces and is arranged between a stationary component (9) and a driving member (3) connected to the winding shaft, wherein two coupling elements are movable axially and in the direction of rotation in relation to one another to operate the coupling by rotating the drive member. In such a drive, one of the coupling members is connected to the drive member (8) by a member (7, 18), which generates a torque between this coupling element (disk 5) and the drive member (8) within a range, and the other coupling element is provided at an end disk of an assembly of a plurality of brake disks (1, 2), wherein the end disk is coupled nonrotatably, but axially displaceably with the driving member. The brake disks (1, 2) are alternatingly connected rotatably to the driving member (3) and to a stationary component (9).
Abstract: A device for generating an aerosol in the course of a respiration gas line, which leads from a respirator to a patient for the patient's artificial respiration.
