Abstract: A measuring device is proposed whose sensors (12) and circuit holders (14) are combined into a compactly structured measuring device (10). This measuring device (10) has a console (11), which is used for containing circuit holders (14) and sensors (12). The measuring device (10), which can be fastened anywhere and is therefore easily accessible, permits a relatively short, direct line routing and consequently, to the greatest extent possible, prevents the accumulation of function-impairing air cushions in the measuring circuits, particularly in pressure measurements. specially embodied bushings (35) that are connected in an airtight fashion to the measuring cells (30) of the pressure sensors (12) reduce the interior space of the cup-shaped pressure sensors (12) so that air cushions are also to a large extent prevented in these components.

Abstract: An electrically conductive housing having a shell-like lid which closes the housing, and the lid and housing mesh with one another on their periphery. The lid comprises a molded sheet-steel part and is provided on its periphery with tonguelike protrusions. The protrusions on their ends self-lockingly engage a wall portion of the housing. As a result, the housing and lid are electrically conductively connected to one another. The shilding action of the housing with the lid for an electrical device disposed in the housing is improved.

Abstract: A measuring element (26) for detecting the movement of a vehicle to be monitored and an electrical circuit (35) for evaluating the measuring signals of the measuring sensor (26) are disposed in a housing (10) of a rotation rate sensor. The circuit (35) is connected with the measuring element (26) with the aid of a flexible printed circuit board (36). The printed circuit board (36) is bent 90 degrees in the area of the measuring element (26) in order to make possible a compact and space-saving construction in the housing (10, 11, 12). The printed circuit board (36) has a cutout (39) and two strips (40, 41) extending parallel with the cutout (39) in the bending area in order to make simple bending possible. It is furthermore possible in a simple way to insert a temperature sensor (45) into the one end (38) of the printed circuit board (36) in order to make possible a simple compensation of the deviation of the temperature.

Abstract: An acceleration switch has a housing having a housing recess, an elongated tilting body located in the housing recess and operating as a seismic mass, a magnetic system, and a reed switch. The tilting body is arranged so that upon exceeding of a predetermined threshold value a control signal is released by interaction of the magnetic system and the reed switch. The magnetic system includes at least two permanent magnets having opposite polarization directions and connected with a magnetic flux conducting body at an end side facing away from the reed switch. The reed switch has contacts located in a magnetic field between the permanent magnets. The polarization directions of the permanent magnets extend perpendicular to a longitudinal axis of the tilting body. The contacts of the reed switch are arranged in a tilting direction of the tilting body.

The Hall element substantially evaluates magnetic flux lines running parallel to a polarization direction of the permanent magnet, so that the Hall element evaluates the magnetic flux lines running parallel to the polarization direction of the permanent magnet in a basic position, and evaluates the magnetic flux lines running in an opposite direction in a tilting position.

Abstract: A positional fixation element is located on a first structural component and positionally fixes a second structural component, which is to be joined to the first component at a predetermined orientation relative thereto. The positional fixation element is substantially in the form of a stud, which protrudes beyond a reference plane of the first component. The positional fixation element is produced by means of a mandrel-like tool, which is pressed into the first component on an incline relative to the reference plane. In the process, material is displaced, so that on the one hand a groove-like indentation is formed, and on the other hand, an accumulation of material having a shape corresponding to that of the positional fixation element is created above the reference plane. The positional fixation element is suitable for positionally fixing electrical circuits, for example, or other components when glued or soldered onto the first component.

Abstract: The high-voltage breakdown strength of the cap, and particularly of the cap portions between adjacent cap towers (4-8), is improved. The skirt (2) of the distributor cap defines an ignition distribution chamber which, in cross-section, is essentially square, with rounded corners. The outer surfaces of the cap are likewise essentially square with rounded corners. The cap towers merge smoothly into the upper end or cap portion of the cap, as well as into the skirt portion, so that no ridges or pockets are formed on the outside of the cap which might accumulate contaminants, impairing the high-voltage breakdown resistance of the cap.

Abstract: The casing (10) of the distributor has integral internal ribs (14) and a bearing body (12) into which at least one of the bushings (16,17) of the bearing is pressed. The shoulders (15) provided on the ribs support an annular sheet steel plate (23) that carries the stationary portion (21) of a Hall transducer. The plate is centered on the sleeve-like end (13) of the bearing body and supported on the shoulders of the ribs, being secured in this position by screws to each of the three ribs. The integral construction of the casing, ribs and bearing body and the screwing down of the plate simplify manufacture and assembly of the distributor.

Abstract: The replacement unit includes a magnet circuit support magnetic barrier member which includes the magnet unit of a Hall generator and is adapted to be fastened to the contact interrupter plate. The unit also includes a distributor rotor adapted for mounting on the contact interrupter cam of the distributor shaft. A plastic reinforcing member of higher mechanical strength is anchored in the distributor rotor. It has a keying projection and extends over the region surrounding said projection, thereby reinforcing the critical section of the distributor rotor. Preferably it is cap-shaped and has an opening for accommodating a retaining member which retains the distributor rotor in the desired position.
