摘要:
A gas generator comprises a tubular housing of a pressure-resistant material and a propellant strand which is incorporated in the housing and provided with an envelope. At least one channel is provided between the envelope and the propellant strand so as to extend in an axial direction. The propellant strand has a substantially circular cross-section and the envelope has a polygonal cross-section.

In a surgical applicator tip for delivering clips used for connecting tissues, the applicator tip includes a magazine chamber, which receives a magazine with clips having tissue engagement claws and an operating mechanism by which the clips can be removed from the magazine and supplied to the front end of the applicator such that the claws project forwardly therefrom the applicator tip for piercing and engaging tissue parts. Each clip includes a shoulder with an elbow lever structure which, with the tissue pierced by the claws, is pushed against the shoulder whereby the claws are tilted toward each other for firmly holding the tissue parts in contact with each other.

A device and method are provided for clips or staples as an effective substitute for suture material when joining body tissue or covering body tissue with a mesh, such as is particularly used in fracture operations. The device for applying a medical lockable clip (1) in a tissue area, includes a) an automatic advancing mechanism oriented in the direction of the tissue area from a starting position and having a guide in the advancing direction for the clip, wherein the clip has two gripper teeth oriented in the advancing direction, b) a stop for the advancing mechanism, and c) a locking element displaceable with the advancing mechanism and having a locking mechanism on the clip side for locking the clip, wherein d) the locking element is displaceable together with and parallel to the advancing mechanism, and e) the stop does not limit the motion of the locking element.

An actuating drive for a rotor blade in a wind power installation is provided with an electric motor and a frequency converter which has a rectifier that is to be fed from a power supply system, a link connected to the rectifier, and a d.c.-to-a.c. inverter for feeding the motor, the link carrying a specified nominal operating voltage in a network-fed normal operation of the frequency converter. Furthermore, an auxiliary energy supply device is provided that is connected to the link. The auxiliary energy supply device includes and energy store which makes available a support voltage that amounts to less than 80% of the nominal operating voltage of the link. A diode is connected between the energy store and the link, and is arranged, with regard to its forward direction, in such a way that it feeds a support voltage from the energy store into the link if the link voltage falls below the support voltage. The diode prevents a current flow between the energy store and the link if the link voltage is greater than the support voltage. A charging device for the energy store has a lower charging voltage than the nominal operating voltage of the link.

An airbag system for a motor vehicle, characterized in that a separate cable-type gas generator (5) is associated with the individual chambers (3) of said air bag system extending in the form of a harness from a central initiator (23) to the respective inflatable chamber (3) of said airbag system.
摘要:
The invention relates to a cord-type gas generator, comprising a solid propellant strand (10) consisting of a gas-generating material, located in a sleeve (12) and a detonation element (18). The solid propellant strand (10) is positioned in the sleeve (12) in such a way, that continuous channels (19) are configured between the sleeve (12) and the solid propellant strand (10) for the formation of a detonation shock wave. The gas generator is characterised in that the solid propellant strand (10) has a reduced woven thickness (W), achieved by the introduction of gaps into the material (slits 13, pores 14), in order to reduce its burn time.
