Abstract: An extrusion-based additive manufacturing process including the step of selectively depositing a molten thermoplastic material (P) on a film or sheet made from or containing a polymer blend obtained by melt blending a mixture made from or containing: (A) 60% to 98.8% by weight of a polyolefin; (B) 0.1% to 30% by weight of a compatibilizer; (C) 0.05% to 20% by weight of an amino resin; and (D) 0% to 5% by weight of an additive, wherein the amounts of (A), (B), (C) and (D) are based on the total weight of (A)+(B)+(C)+(D).

Abstract: A drive device, comprising a first housing part and a second housing part which can be displaced with respect thereto, and comprising a motor assembly, which comprises a rotor, two mounting elements and two permanent magnet shells, and if desired comprising a transmission assembly and/or a sensor unit associated with the motor transmission.

Abstract: A positioning device is e.g. used for positioning the door of a motor vehicle in an opened position. The positioning device comprises e.g. a cylinder and a piston rod which extends inward and outwards of the cylinder through one end thereof. A flank face is provided at the inner wall surface of the cylinder. The piston rod carries a piston. The piston is provided with a counter-arresting ring which engages the flank face in a predetermined position. When the piston passes across the arresting flank of the cylinder, the counter-arresting ring is moved radially inwards with respect to the axis of the piston rod against elastic resistence. So, an increased resistance occurs against the axial movement of the piston rod with respect to the cylinder. This increased resistance against axial movement positions the door with respect to the body frame of a motor vehicle in a predetermined opened position and avoids that the door is closed unintentionally.

Abstract: Mould locking dowel (11) for concrete, provided with a dowel sleeve (21) traversed by a plurality of holes (26) arranged on the circonference and inclined with respect to the longitudinal axis, wherein are inserted pins (29) to keep the dowel (11) into a hole (12) in the concrete. In this mould locking dowel (11) intended for concrete and of easy handling, the holes (26) for the pins (29) are arranged in the front end areas of the dowel sleeve (21) according to a sharp angle with respect to the longitudinal axis (27) of the dowel sleeve (21) so that the pins (29) penetrate, when in the final drive-in state, only on a portion of the diameter thereof in the concrete and that they are during the drive-in motion, brought throughout their length into the holes (26) arranged in part as an open channel (28) in the dowel sleeve (21).

Abstract: In a windshield wiper device each wiper blade has a wiper element with a lip applied to a windshield to be wiped and a back portion held in an elastic rail made from elastic plastics. The wiper element is secured on the elastic rail against mutual displacement in the direction of elongation of the rail. A two-part yoke system which engages the elastic rail provides for a uniform distribution of contact pressures exerted on the wiper elements.

Abstract: A drilling tool for drilling a cylindrical borehole of relatively great depth in a soft material and then forming a conical enlargement adjacent the bottom of the borehole includes an axially elongated tool shank with a first drill at one end for cutting the cylindrical borehole and a second drill adjacent the first drill for cutting the conical enlargement. The second drill is formed of bit holders pivotally connected to a flattened part of the tool shank. An adjustable stop is provided on the tool shank for determining the depth of the borehole. A connecting link guide located within the tool shank interengages the bit holders and the tool shank. When the desired depth is reached, due to relative axial displacement between the tool shank and the connecting link guide, the bit holders are pivoted outwardly so that the second drill can cut the conical enlargement.

Abstract: An anchor bolt is arranged to be secured in a relatively deeply drilled hole having a conical enlargement adjacent the base or inner end of the hole. The anchor bolt is formed of an axially elongated tie rod and an anchor located on the end of the tie rod which is inserted into the base of the drilled hole. The anchor is made up of a number of radially expandable sleeve segments. The anchor also includes a cone element for expanding the sleeve segments radially outwardly into the conical enlargement in the hole. The sleeve segments have an outside radius variable in the axial direction of the segments. The radially outer surface of the segments is substantially smooth for their axial length. At the smaller diameter end of the sleeve, the segments are held together by an annular elastic disc.

Abstract: A tool which makes an undercut in the surface surrounding a drill hole in a layer of coal has a head plate which abuts against the surface at the inner end of the hole when the tool is inserted and which is installed at the front end of a rotary tubular guide for two bit holders constituting one-armed levers and having front portions provided with bits and being movable radially outwardly through windows in the guide. The rear portions of the holders are coupled to the front part of a reciprocable rotary shank which can be moved forwardly to expel the bits from the guide while moving the holders forwardly. When the shank is retracted, the bits are withdrawn into the guide. Such movements of the bits are caused by a transverse pin mounted in the guide and extending through elongated cam grooves in the median portions of the holders.
