Abstract: An automated trolley system for wind turbine tower segment tightening is presented. The system consists of a body with first and second portions at either end, with the first portion mounting close to bolts and driving on top of a flange while being guided by wheels, and the second portion pushing against the interior of the tower through wheels to move the body around a flange in order to automatically tighten the flange. The system includes at least one wrench socket with or without an internal pattern attached to a plate, and each wrench socket is designed to use electric or hydraulic torquing and/or tensioning to tighten each bolt that is placed on top rather than the bottom. The system comprises a winch with a balancer adapted to screwing the wrench socket with or without internal pattern.

Abstract: This invention relates to methods for controlling a TNI-apparatus (1). One method can measure the actual gas temperature at the outlet of the humidifier (19). One method can determine a set gas temperature (34) of the gas at the outlet of a humidifier (19) of the TNI-apparatus (1) in dependence on an ambient temperature (25) of the TNI-apparatus (1), or a set gas temperature (34) of the gas at the outlet of a humidifier (19) of the TNI-apparatus (1) in dependence on a gas flow (28) in the TNI-apparatus. One method can determine a set gas temperature (34) of the gas at the outlet of a humidifier (19) of the TNI-apparatus (1) in dependence on a comfort value (30) predetermined by a user, or adjust the heating power of a heating wire (26) in a nasal cannula (27) of a TNI-apparatus (1) in such a way that a gas exiting the nasal cannula (27) has approximately the same temperature, which the gas had when it exited a humidifier (19) of the TNI-apparatus (1).

Abstract: The invention relates to a nasal cannula for an anti-snoring apparatus, comprising a forked tube pneumatically connected to apertures, which are embodied and positioned in such a way that air can be administered into the nose of a user via these apertures. The nasal cannula further comprises a heating wire extending in the interior of forked tube in such a way that the heating wire can heat the air supplied through the forked tube. The invention moreover relates to a nosepiece and to a Y-shaped element for nasal cannula including internal radius steps at tube connection points. The invention further relates to a nosepiece and to a Y-shaped element having rounded off transition regions. The invention finally relates to a method for avoiding condensation in nasal cannulas. To this end, the gas is heated as it flows through the tubes of a nasal cannula.

Abstract: A method for the electron-microscopic observation of a semiconductor arrangement is provided. It includes providing an electron microscopy optics for imaging secondary electrons emanating from the semiconductor arrangement within an extended object field on a position-sensitive detector, providing an illumination device for emitting a primary energy beam, directing the primary energy beam to at least the object field for extracting there secondary electrons from the semiconductor arrangement. The semiconductor arrangement comprises a region with an upper surface provided by a first material and a recess with a high aspect ratio which is surrounded by the upper surface and has a bottom provided by a second material.

Abstract: An airbag, particularly for the knee or head region of a vehicle occupant, has a substantially cylindrical main region. The airbag comprises a substantially cylindrical fabric tube whose lateral ends are stitched after folding the tube into a predetermined pattern having at least two looped segments. The fabric tube can be formed by joining the lateral edge of a rectangular fabric blank.

Abstract: A toothbrush comprises two parts (2, 3) which are pivotable relative to one another, of which a first part (2) serves as a handle and of which a second part (3) carries a brush-head (5), a spring (7) being arranged between the parts and having one end (8) fixedly connected to one (2) of the parts and having another end (9) which engages with a wall portion (11) of the second part (3), the second part (3) being pivotable relative to the first part (2) against a pressure exerted by the spring (7) during use of the toothbrush, which spring snaps when a given pressure threshold (P.sub.d) is exceeded, after which the second part (3) is subjected only to a bending load in the absence of a pressure (Q) directed in the longitudinal direction of the spring (7) and exerted by the wall portion (11), and resumes its original position when the pressure has decreased.

Abstract: In a shaving apparatus (1) comprising a housing (2) and a shaving head (10) with a shaving-head frame (12) and a foil frame (31) at least two helical pressure springs (57, 58) act between the two frames (12, 31) and are each arranged in a circumferentially closed duct (45, 46) provided in one (31) of the two frames (12, 31), which duct also accommodates a piston-like pressure member (47, 48) which projects from the relevant duct (45, 46) and bears against the other one (12) of the two frames (12,31).

Abstract: A toothbrush is provided having two housing sections (1, 2) which are pivotable relative to one another, of which a first housing section (1) serves as a handle and accommodates a drive unit (4) for driving a drive shaft (5), and of which a second housing section (2) carries a brush-head (3), which is drivable by the drive shaft, which second housing section (2) is pivotable relative to the drive shaft (5) about a pivot (6).
