A connecting device suitable for connecting a movable conducting terminal (2) of a switching device (3) to a stationary conducting terminal (4) of a switchgear apparatus (5), comprises: a pin-group (6) suitable for being inserted into an opening (7) obtained in a connection-region (10) which is defined by mutually overlapping portions of the movable (2) and stationary (4) conducting terminals, the pin-group (6) having a head-end (8) and a pressing-clamping-end (9) which are suitable for being positioned at opposite sides with respect to the connection-region (10). The pin-group (6) is movable from a releasing position (15), in which a mutual separation of the movable (2) and stationary (4) conducting terminals is enabled, to a locking-clamping-position (16), in which the movable (2) and stationary (4) conducting terminals are reciprocally clamped. There are provided locking-positioning-means (14) configured for keeping the pressing-clamping-end (9) blocked in the locking-clamping-position (16) and for imparting to the pressing-clamping-end (9), upon a movement of the pin-group (6) from the releasing position (15) to the locking-clamping-position (16), a tightening displacement (17) so as to generate a tightening force which presses the mutually overlapping portions against to one other. The connecting device (1) is provided with tightening-control-means (40) configured for controlling the tightening force so as to set a desired value of tightening-contact-pressure between the mutually overlapping portions.

A turbine blade locking device for axial retention of a turbine blade (1) having a blade root (3) inserted in an axially extending profiled lobe slot (5) of a turbine disk (4), wherein, a sealing fin of a blade platform (10) includes, over part of its axial length, a retaining groove (6) featuring a semicircular cross-section, a disk lobe (7) of the turbine disk (4) is provided with a semi-spherical recess (8), and a ball (2) is fitted into the recess (8) and the retaining groove (6).

Disclosed is a rolling tool which serves for working - in particular rolling smooth - an inner lateral surface of a cylindrical clearance. For this purpose, the rolling tool has at least one rolling body, which is held in the rotatably drivable rolling tool, and can be taken along by said tool on a peripheral path along the inner lateral surface. In this case, the at least one rolling body is inserted into a radial clearance in the rolling tool and can be subjected to a pressurized fluid from the inside to the outside along the radial clearance. According to the invention, the fluid is an aerosol. The aerosol is a fluid mixed with gas and serves for hydrostatic bearing and lubrication. In this case, the amount of fluid required is reduced in comparison with the prior art - on the basis of minimal quantity lubrication (MQL).

The invention relates to an illumination device (100). The illumination device comprises a lamp tube (1) with two open ends, a light engine (2) arranged in the lamp tube (1), a carrier for carrying the light engine (2), and two end covers (3) for sealing the open ends. The illumination device (100) is characterized by further comprising a diffuser (4), wherein the carrier for carrying the light engine (2) is kept on the diffuser (4), and the diffuser (4) is kept on the inner wall of the lamp tube (1).

A midsole for footwear includes at least one solid or hollow cushioning tube positioned therein for improving the cushioning of the midsole. Preferably, the midsole includes a plurality of cushioning tubes fabricated of an elastomeric material. The tubes may vary in diameter and / or wall thickness relative to one_another for varying the cushioning and stability characteristics of the system. Each tube may also vary in diameter and / or wall thickness along its length.

The present invention relates to a novel process of preparing an enantiomerically enriched Gamma-amino acid, such as enantiomerically enriched (S)-pregabalin.

A data observation device observes internal data of a control device for controlling a machine tool, an industrial machine, an industrial robot, or the like which has at least one drive shaft driven by one selected from a servo motor, a spindle motor. The device includes: means which specifies observational data targeted for observation; means which specifies trigger data used to determine a timing of a trigger for starting and / or terminating acquisition of the observational data; means which sets a trigger condition for applying the trigger based on a value of the trigger data; and means which judges whether or not the trigger condition is satisfied in the control device, selectively starts and terminates acquisition of a value of the observational data, and displays the acquired observational data.
