A turbine blade includes an airfoil, platform, shank, and dovetail integrally joined together. A cooling chamber is located under the platform and has a portal exposed outwardly from the shank. A damper seat surrounds the portal and is recessed under the platform for receiving a vibration damper to sealingly close the chamber across the portal.

A turbine stage includes a row of airfoils and their platforms spaced laterally apart to define flow passages therebetween. Each airfoil is integrally joined to its platform at a funnel-shaped fillet along the pressure side of the airfoil which decreases in size from the leading edge towards the trailing edge. A field of film cooling holes extends through the platform along the fillet for discharging film cooling air.

The invention concerns a power-assisted lock for doors, hatches hoods or hard tops of vehicles and the like. In addition to a known pivotal latch and a catch for a releasable engagement with the pivotal latch there is a control disc pivotally mounted in the housing of the lock. A manual or power actuated drive means is attached to the control disc for the closing and opening operation. The pivotal latch and the control disc have a drive connection providing for limited play. The arrangement together with the catch leads to a locking of the control disc before a closing operation and an unlocking of the control disc by turning the pivotal latch during the closing operation of the lock. The pivotal latch has the usual pre-lock position.

A method facilitates the assembly of a stator assembly for a turbine engine. The method includes providing a cantilevered shell including a first end and a second end, and coupling a second member within the turbine engine. The method also includes coupling the shell to a frame such that the shell extends circumferentially around at least a portion of the second member such that a non-uniform circumferential radial gap is defined radially between the second member and the shell using methods other than directing machining of an inner surface of the shell, and wherein the non-uniform circumferential radial clearance gap becomes substantially uniform during operation of the engine.

A locking-aid device is disclosed for a lock, especially for a vehicle door lock or flap lock, in which a pneumatic single-acting locking-aid drive is provided for displacing an abutment for a rotary latch out of a catch position into a locking position, in which the abutment is secured positively by means of a detent pawl. According to the invention the detent pawl can be lifted out, during the opening of the lock, independently of a movement of the locking-aid drive by means of an operative connection. This can be brought about purely mechanically or by means of a separate drive for lifting out the detent pawl during the opening of the lock, so that the abutment can always jump into its catch position immediately during or after the opening of the lock and thus also allows a successive multiple activation of the locking-aid assistance.

A motor veicle compartment closure lock with a locking wedge (2) attached on the closure, and lock elements attached on an opening frame for the closure. The locking wedge (2) can be retracted, in a powered way, from an extended, open position into a pushed-in, locked position and, for this purpose, is coupled by a lever mechanism (3) to a power transmission element (5) with a powered drive. The powered drive can be built especially small and light because the drive is made as a drive that operates only in one direction (locking direction) and returns automatically in the opposite direction. Power transmission element (5) is slaved or can be slaved to the locking wedge (2) in the locking direction and moves freely in the opposite direction. A shifting lever (6) is provided that is carried by the power transmission element (5) in the locking direction and is spring-loaded in the opposite direction. The shifting lever has an engaging part (7) that moves in a shifting link (8), and the engaging part (7) can be brought by a movement in the locking direction, from an open rest stop (9), to lie against a locking stop (10) and can be brought, by renewed movement in the locking direction, from the locking stop (10) back again to the open rest stop (9).

The invention concerns a securing device for swivelling components of vehicles, in particular for engine hoods of motor vehicles. A securing hook which, after the release of the swivelling component, initially maintains a catch connection between this swivelling component and a fixed location mating component until the securing hook is pivoted into a release position by means of a manipulator. The manipulator, which is recessed when the swivelling component is locked, is automatically transferred into an accessible operating position by utilization of a forced advancement of the swivelling component relative to the mating component initiated by the release procedure. A control edge effectively connected to the manipulator and supported on the mating component is moved in the opening direction of the securing hook by sliding along the mating component. In order to permit an increase in the automatic manipulator advancement without doubts about safety and without sacrifices to operational comfort, the control edge is part of a control hook which is supported so that it can move relative to the securing hook and the motion of the control hook is only coupled to that of the securing hook after it is in advance of the latter.
摘要:
Motor vehicle door lock or the like with a pivotally mounted locking catch (3), a pivotally mounted pawl (4) which blocks the locking catch (3) in a preliminary locking position and a main locking position, and with a locking mechanism (5) for operating the locking catch (3) and pawl (4). The locking mechanism (5) has an outside release lever (6), and when outside release lever (6) is operated, pawl (4) can swing into a release position freeing locking catch (3), e.g., by being lifted. The manipulation of the lock is improved since, in the opening movement, when the locking catch (3) is in the main locking position and the release lever (6) is operated, the pawl (4) is swung into the release position, where it is retained independently of the further operation condition of outside release lever (6) until the locking catch (3) has passed the preliminary locking position.
