A mold component for forming a member consisting of a nondevelopable surface, such a member being an airfoil such as a wing or the like, is provided with an interior cavity in the shape of a developable surface which approximates the nondevelopable surface. In forming the mold cavity, points of equal tangential inclination on the non-developable surface are joined by straight lines and then the areas between the straight lines are formed as flat planar surfaces, thereby to form a developable surface which is an approximation of the nondevelopable surface. A flat planar development is then formed from this developable surface and bends are made therein at the straight lines in order to form thereby the mold cavity. A substantial number of said bends extend non-parallel to each other and none of the bends intersect.

A rotor for a rotary wing aircraft has two damping structures on the outs of the blade angle adjustment sleeve. Each damping structure is a sandwich of an elastomeric layer between two stiff cover layers. A two-armed strut passes through the blade neck and is connected at its center in a pivoting manner to the blade root. The threaded outer ends of the two-armed struts pass through the respective sandwich for yieldingly connecting the radially inner end of the blade angle adjustment sleeve to the blade root. By tightening nuts on the threaded strut arms the elastomeric layer may be compressed. Thus, the damping structure performs, in addition to the damping function, a connecting function for the blade angle adjustment sleeve.

The invention provides aqueous liquid pharmaceutical compositions comprising arbekacin and chloride ions. The compositions are well tolerable for use in a method for treatment or prevention of a disease of the upper or lower respiratory tract, wherein the composition is aerosolized and inhaled by the patient. Furthermore, the invention provides arbekacin hydrochloride.

摘要:
An electrical contact device for an arrangement includes two apparatuses, between which a relative movement takes place along a first movement path. In at least one embodiment, the electrical contact device includes a first contact, including a first contact surface, and includes a second contact including a first multiplicity of contact arms, each provided with a contact projection for making contact with the first contact surface. In at least one embodiment, in order to prevent excessive friction wear to the first contacts even when the contact projections of the associated second contacts are arranged successively in the same direction as the first movement path, at least one device is provided for controlling a relative movement between the two contacts along a second movement path, which runs parallel to the first contact surface of the first contact and obliquely with respect to the first movement path.

摘要:
The invention relates to a device which is used to deliver packets (1) comprising a pouring spout (2) to a rotating star-shaped element (3). A guiding rail (4), which co-operates with a pouring spout (2) and which is used to receive the bag in a displaceable manner, is provided with a removal end (8). The aim of the invention is to produce a device wherein delivery is simplified and high clock frequencies are ensured. As a result, an upper slider (7) engages with the bags (1) at the pouring spout (2) in the region of the removal end (8) of the guiding rail (4), and a drive unit (9) displaces the upper slider (7) between a removal position (10) on the removal end (8) of the guiding rail (4) and a delivery position (11) of the orbit of the receiving elements (12) of the star-shaped element (3).
