The invention relates to a fixing element (1) for fixing insulation and scaling tracks on a fixed substructure. Said element comprises a screw (9) and a large washer (7) with a cylindrical extension (8). The screw (9) has two thread segments (13, 14), wherein one thread segment (13) interacts with the through hole in a reciprocal thread engagement located in a narrowed area (12) of the cylindrical extension (8). An axial relative movement of both parts can be achieved by reciprocally rotating the cylindrical extension (8) and the screw (9).

A rotor coupling (10) including a first member (12) rotatable about a first axis of rotation (14) and a second member (16), engageable with the first member, and rotatable about a second axis of rotation (18). The rotor coupling (10) further includes at least one torque pin (24) for transmitting torque between the first and second members such that the first and second axes of rotation are allowed to respectively angularly vary during rotation of the rotor coupling.

A container (1, 2) for storing and dispensing a liquid, the container including an access port (16) having a frangible seal (18) for allowing contained liquid to be dispensed. A vent (19) permeable to vapour but impermeable to liquid is also provided so that vapour may be vented from the interior of the container.

A screw holder mountable on a drive unit having a tubular passage with two axially-aligned sections, each provided with locking and centering elements, such that a screw inserted into such holder can initially only penetrate until the screw head is reliably held and suspended in the first section by the locking elements. The force of the centering and locking elements upon the screw head is overcome when the apparatus is placed on the screw location and an engagement tool coupled to a drive shaft is brought into driving engagement with the screw head, which driving movement forces the locking elements radially outward in response to the axial load upon the screw head and the passage of the screw head therethrough. After the screw head passes through the first section within the tubular passage, the screw shaft is engaged by the centering elements of the second section. The centering elements of the second section are then also forced back as the head of the screw passes therethrough.

A device for processing a belt strap for storing screws, in which the belt strap has a flat, U-shaped cross section that has a periphery that has a ratio of no more than 11:10 relative to the non-flanged belt. A guide device for the belt strap guides and holds the belt strap. The screws can be pressed out from the upper side of the belt strap. The guide device (3) has two guide slits (10) receiving the belt strap (2) in at least the region of the flanges (4), each slit being L-shaped in cross section and each having a contact surface (5) for the underside (6) of the belt (20) and a guide rib (11) extending across the flange (4). A distance (M) of each guide rib (11) from the contact surface (5) has a value greater than the belt thickness (D) and less than a length (Q) of a corner diagonal (12) of the belt strap (2) extending in the U-shaped cross section between the points at which the inner side (7) of the flange (4) intersects the upper side (9) of the belt (20) and one of the outer sides (17) of the belt strap (2) intersects the underside (6) of the belt (2).

The invention provides a fan (10) with a blade (12), suitable for use as a ceiling fan. Blade (12) may be regarded as a single blade, although shaft (18) is not attached to blade (12) at one end thereof; rather, shaft (18) is attached to blade (12) at a point between first end (14) and second end (16). Blade (12) is balanced by counterweight means (22) located in blade (12). In on embodiment, blade (12) is connected to shaft (18) by means which permit angular movement, such as a teeter hinge.

The invention relates to a device for screwing in magazine-fed fastening elements that comprises, inter alia, a plastic retainer (13). Between the magazine for the plastic retainers (13) and feeding elements (10) for feeding the plastic retainers (13) to the position of screwing, a picking system (16) is provided. Said picking system (16) is configured by a lever (17) that can be swiveled about an axis (19). An extension (26) that is formed on the lever arm (21) and a stop element (23) that is formed on the lever arm (20) and that can be pushed back against the force of a spring engage in the feed channel (22) alternately and sometimes also at the same time.
