Abstract: During the positioning of a control device for controlling an electromechanical drive, contact elements, which are connected to the control device in a fixed manner, are positioned in relation to one or more openings in a connector collar. To position the control device, the latter is displaced into a predetermined position. The predetermined position is defined, for example, by a guide or a stop. The contact elements are a component of an electric and/or optical junction which connects the drive device to other functional units, for example to a door control device or a motor vehicle battery. To position the contact elements in the connector collar of a connecting element which lies on the side of the drive device in the junction, the contact elements are positioned in relation to openings in the connector collar by being displaced together with the control device into the predetermined position.

Abstract: An electro-mechanical drive device for adjustment devices of a motor vehicle, more particularly for a window lifter, has a gearing with a gear housing, an electric motor mechanically connected to the gearing, a control device mounted in the gearing housing and having at least one power semi-conductor for controlling the electric motor, and means as a heat sink thermally coupled to the power semi-conductor to draw off the waste heat from the power semi-conductor. The means which as heat sink draws off the waste heat from the power semi-conductor is integrated in the gear housing. With the integration of the means for drawing off the waste heat into the gear housing it is possible for the means to undertake further mechanical or thermal functions extending beyond the function as heat sink.

Abstract: A roof rail for vehicles with a tubular gallery rod (1) and a pair of rail feet (2) which are arranged at its ends, are supported on a vehicle's roof (4). The rail feet (2) are each formed from the same length of material as the gallery rod (1) and consist of bent and flared end sections of the gallery rod (1). The gallery rod (1) has a continuously increasing cross section proceeding from the transition region of one rail foot (2) up to the transition region into the other rail foot (2). A manufacturing process for the roof rail is also disclosed in which a length of extruded material having an expansion fold is formed with arcing end portions. The length of material is then placed in a molding tool and pressurized to expand the material such that it forms a roof rail.

Abstract: The invention relates to a process for detecting the position and direction of movement and for detecting the dynamic characteristic values of remote-controlled displacements of an adjustable object. According to the invention a signal is detected and evaluated which is solely made up of a system-characteristic signal or the overlapping of several system-characteristic signals. The aim is to achieve a high dissolution of the aforesaid values which are to be detected without using additional sensor or transmitter elements whilst incurring only small production costs.

Abstract: A sampling arrangement for a grain stream to extract a grain sample for analysis from the grain conveyed into a grain tank. The sampling arrangement comprises a closed crop guide that is provided with a closing arrangement that can be operated for the controlled extraction of a crop sample and transports this to a sample container of a sample extraction arrangement.

Abstract: A rotary idle-speed actuator for controlling a throttle cross-section in a line carrying combustion air for an internal combustion engine has an actuating motor with a stator and a rotor. The rotor is mounted on a shaft of a throttle member which more or less opens a control opening. The rotor has a cup-shaped form with a bottom and a cylinder-jacket-shaped wall. The stator has field windings and is arranged together with the field windings inside the rotor, and the stator is mounted only at its end which is opposite to the bottom of the rotor.

Abstract: A rotational control device for the setting of angles in actuators, in particular of a restricting device used for determining the flow cross-section in a flow line for internal combustion engines, has an electrical setting motor with a two-pole status and a two-pole permanent magnet rotor. To obtain a robust setting motor, which is technically easy to manufacture in a compact construction, the stator poles are designed as claw poles and the stator winding is located as a toroidal coil in a ring space formed by the claw poles and a ring casing which is coaxial with these, for the magnetic return path. The stator winding is energized by a d.c. supply, with reversible current direction. The magnetic resistances in the magnetic return path and across the claw poles are calibrated such that in the event of a currentless stator winding, the permanent magnet rotor engages in the pole gaps between the claw poles.

Abstract: In a rotary actuator (1) with rotary slide valve (3) for controlling a throttle cross-section, the sealing of the pneumatic (16) and of the electrical part (17) is to be improved. For this purpose, the shaft (11) is supported twofold, both on this side and on the other side of the rotary slide valve (3). Both roller bearings (13, 14) are located in a one-piece housing (12). As a result, the tolerance-related width of the air gap between rotary slide valve (3) and control opening (6) is reduced, on the one hand, and, on the other hand, an isolating seal between the parts (16) and (17) is formed by the bearing (13). The rotary actuator (1) is particularly suitable as idle-speed rotary actuator for internal combustion engines.

Abstract: A harvesting machine is provided with a foreign material protective device to extract stones, sand and other material from the harvesting goods which are gathered by the header. With the present invention, the protective device is provided with a housing defined by two longitudinal walls, perpendicular to the flow of crop material, and two side walls, parallel to the flow of crop material. The longitudinal walls of the housing diverge slightly towards the outlet opening of the housing. The outlet opening is closed by a door having an impeller which extends into the housing when the door is closed. The impeller ejects material from the housing through the outlet opening when the door is opened.

The bearing shield prevents damage to the shaft and the toothed part of the actuating motor prior to its assembly with the gear unit.

Abstract: A window-lifter drive unit for a cable-window lifter which includes a housing in which a worm gear as well as a cable drum taken along by the worm gear are provided between two mutually opposite wall parts. A bearing bolt 40 is supported with one end thereof in one of the two wall parts and at the other end thereof in the other wall part by way of a bearing bushing. The cable drum is retained at the outer circumference of the bearing bushing; a circumferential collar of the bearing bushing forms a securing member against pulling off the cable drum from the bearing bushing. Combined with a simple construction and low manufacturing costs, a partial unit including the worm gear as well as the bearing bolt can be separated without difficulty from a partial unit including the cable drum as well as the bearing bushing which facilitates assembly and repair work.

Abstract: A safety belt system comprising a belt displacer for a belt which is so constructed as to transport a section of the safety belt between a retracted position and a seizing position for purposes of facilitating fastening of the belt, is provided for its use with a three-point safety belt, in which the belt ends are attached at the seat bearer respectively at the seat on one side of the seat and run over a belt base point and a belt shoulder point. The belt displacer includes a belt deflection element which within the area between the belt ends engages at the belt and is displaceable along the belt. In the seizing position of the belt displacer, the belt buckle to be inserted into the belt lock is arranged within the area of the belt deflection element and can therefore be easily reached. As soon as the belt buckle is inserted into the belt lock, the belt displacer travels back into the retracted position.
