In the case of a locking mechanism (1) for a vehicle seat, in particular for a motor vehicle seat, having a pivotably mounted pawl (11) for locking to a mating element (B), and having at least one securing element (25, 31) which secures a locked state by interaction with a first functional surface (21) of the pawl (11), and secures an opened state by interaction with a second functional surface (41) of the pawl (11), the securing element (25, 31) exerts an opening moment on the pawl (11) in the opened state.

A device for borderless printing on imaging material by means of an ink jet printer has a support surface against which the imaging material lies while printing ink is applied to it during the printing process. The support surface has cutouts and is hydrophobic and/or oil-repellant, so as to repel printing ink that is sprayed outside the borders of the imaging material.

A variable-pitch propeller, especially for a sport board, has angularly displaceable blade support plates which can be rotated about respective radial axes. The plates are provided with radially inwardly directed claws which engage in circumferential grooves of bases of the blades. The latter can have radial projections reaching beneath the claws. The resulting bayonet connection simplifies mounting and dismounting of the propeller blades even under water.

The positions of blade members on a hub of a propeller for a sport boat is determined by replaceable keys or plates fitted into openings of corresponding shape and having differently located bores determining the pitch setting. The recess can be in the seat of the hub directly or in a blade carrier plate which can be mounted on the hub.

A controllable-pitch propeller for a sport-type watercraft has a push rod eccentrically connected to each blade displaceable in a bore of the propeller hub. The push rod is sealed with respect to the end of that bore by a multifold bellows whose radial flange is clamped by a cap of an axial flange of the housing in which the bore is provided.

The invention relates to benzothiazoles and benzoxazoles of general formula ##STR1## wherein R.sup.1 to R.sup.3, X, Z and n are defined as in claim 1, the enantiomers, diastereomers and salts thereof, particularly the physiologically acceptable acid addition salts thereof which have valuable properties, particularly an inhibitory effect on cholesterol biosynthesis, pharmaceutical compositions containing these compounds, the use thereof and processes for preparing them.

The invention pertains to a vacuum pump (1) with a closable line (63, 102) through which gas ballast can be fed into the pump chamber (8, 9); to eliminate the danger that a recipient hooked up to the vacuum pump may be charged with air in the event of a pump failure, the invention proposes that the line be equipped with a control valve (59, 60, 61; 98, 99; 109, 110) to regulate the gas ballast feed as a function of operating conditions, such that the line is closed in the event of a pump failure.
摘要:
A drive for a boat has a propeller hub rotatable about a main axis extending in a normal travel direction, a plurality of blades projecting generally radially of the main axis from the hub and each pivotal so as to be of variable pitch, and respective blade rods extending axially and displaceable axially relative to the hub to vary the pitch of the blades. A stator carried on the boat downstream in the direction from the hub and nonrotatable about the axis rotatably supports a cylinder housing that is releasably connected to the rods for joint axial movement therewith. A piston displaceable along the axis in the cylinder is releasably connected to the hub for joint axial movement therewith. Pressurizable lines extending through the stator are connected to the cylinder for alternately pressurizing the piston and thereby relatively axially shifting the rods and hub.
