Abstract: In a process for the profiling of a grinding worm (1) with at least two grinding width zones (4, 6) with differently modified thread profile for the grinding of spur and helical gears with three-dimensionally modified flank profile, the grinding width zones (4, 6) are arranged overlapping in order to gain optimum exploitation of the grinding worm width (3). In one variant, profiling of the grinding worm (1) is performed with an abrasive coated profiling gear (25) with a tooth flank geometry and facewidth differing from that of the workpiece to be ground. By suitable selection of the diagonal ratio and the allocation of the width zones (28, 29) of the profiling gear (25) to the grinding width zones (4, 6) of the grinding worm (1), it is possible to adapt the modifications of the grinding worm flanks to the requirements of the workpiece without having to alter the flank geometry of the profiling gear (25).

Abstract: In the continuous generation grinding of a gear the modifications of tooth trace contours and/or corrections of tooth trace deviations determined by flank measurement are specified separately for the left and right flanks (3, 4) of the gear (1). By means of these data, supplementary motions of the NC machine axes across the face width of the left flank (3) and the right flank (4) of the gear (1) are calculated in a control system of a gear flank grinding machine, by means of which a grinding worm produces the specified modified or deviation corrected tooth traces on the left flanks (3) and the right flanks (4) of the gear (1) in one and the same grinding stroke.

Abstract: A connector is mounted on a circuit board by a pair of elongated fasteners (23) that each have a connector end (29) that is fixed to the connector housing and a board mount end (28) that is fixed in mount holes (80) in the circuit board. The board mount ends of the fasteners are press fit into circuit board holes as the termination ends (42) of the connector contacts are inserted into plated holes in the board. Each fastener is attached to the connector by passing the connector end of the fastener through a hole (24) in a plate-like metal wing (74) of the connector and then press fitting the connector end of the fastener to the wing. The fastener has an elongated pin-like middle portion (26) that can be bent 90° so most of the connector can lie beyond an edge (70, 72) of the circuit board and partly in the plane of the circuit board.

Abstract: In a connection arrangement between a sensor and connection leads, only a small installation space is required. To this end, the connection arrangement has a signal amplifier, which is electrically contacted by means of bond connections with the sensor and the connection leads. This is achieved by means of connecting elements, which are designed as thin sheet-metal shaped parts and are fixed with tab-shaped end sections in a housing of plastic, in which the signal amplifier is also inserted. The end sections, the signal amplifier, and the bond connections are arranged in a space-saving manner in roughly one plane. The connection arrangement is especially suited for sensors used to measure the speed of motor vehicles.

To this end, the plug connector has contact elements, each having an attachment section and a contact section, whose attachment sections are manufactured from a one-piece self-supporting punched grid. The thickness d of the punched grid is independent of the thickness a of the contact sections, which are produced separately from the attachment sections and are assembled with them to form the contact elements, which upon integration into a housing of an electrical device are partially equipped with a sheathing made of plastic. The plug connector is preferably used in automotive engineering, for example, in electrical control units with highly integrated circuits.

Abstract: A method and apparatus centers of an electron beam (3) in a surface coating installation with movable substrates. A rotating magnetic field is superimposed on a main magnetic field which serves to guide and focus the electron beam. A focal spot of the electron beam is thus caused to rotate about a theoretical axis (17) of the electron beam (3) and the beam sweeps the entire surface (32) of a raw material source (4). Changes in the consumption of reactive gas supplied to the installation are measured by a flowmeter (21). Through a control unit (20) connected to the flowmeter, stationary magnetic fields are superimposed on the rotating magnetic field and the electron beam (3) is aimed at the center of the surface (32) of the raw material source (4) as a function of variations in the reactive gas flow.
