A rotary position transducer for generating electrical rotary angle signals as a function of the pivoted position of a rotary device, in particular a throttle valve in the fuel supply system of an internal combustion engine, has a first carrier with concentrically disposed electric contact tracks and a second carrier with fixedly disposed wipers, which rest with axial pressure on the contact tracks. One of the two carriers is rotatable relative to the other, and the rotatable carrier has a securing element for coupling of the rotary device in a manner fixed against relative rotation. To suppress a transmission of radial and axial play of the rotary device to the arrangement of wipers and contact tracks, the securing element is joined to the carrier via a spring coupling that is torsionally rigid in the rotational direction but highly elastic in the axial and radial direction.

A device for noise peak suppression during a potentiometer evaluation has a potentiometer located between a reference voltage and mass and having a slider with a slider output, a control device adapted to receive a signal from the slider output of the potentiometer, and an amplifying unit located between the potentiometer and the control device so that a signal picked up from the slider output is amplified in the amplfying unit before being supplied to the control device.

A device for contactless measurement of a rotational angle of a rotating part that is rotatable via a rotating shaft. The device includes a cylindrical coil carrier with sensor coils and a tubular body of electrically conductive material that is firmly attached to the rotating shaft and which surrounds the coil carrier with radial play and has an electrically non-conductive zone extending circumferentially in the vicinity of the sensor coils. For the sake of an easy-to-assemble structure, the tubular body is slipped onto a face end of the rotating shaft in a form-fitting manner and the tubular body is surrounded with radial play by a housing cup, from the bottom of which the coil carrier, which is integral with it, coaxially protrudes. The housing cup is joined in a floating manner to a housing that receives the rotating part.

In known air flow rate meters, the initial tension of a spiral spring, which generates the restoring force on the baffle valve, is adjusted by the snapping of a locking spring into gaps between the teeth of a tooth ring provided on the spring housing. However, the tooth spacing cannot be made arbitrarily small. Accordingly, a way to enable finer adjustment of the initial tension is needed, so that a measurement can be made even at low idling speeds and with a small aspirated air quantity. In the air flow rate member according to the invention, the locking spring engages a detent element, which facing the toothed ring has an inside serration, the spacing of the teeth of which is less than the spacing of the toothed ring; when the spring housing rotates, detent increments that correspond to the spacing of the inside serration are attainable. Quite generally, the embodiment according to the invention enables sensitive adjustment and locking of a spiral spring serving as a restoring force.

In an automatic transfer machine tool with circular supply movement for workpieces to be sequentially worked on in respectively separate working stations (I-V), a stepwise indexable workpiece holder (10) is journalled on a center post (8), the workpiece holder (10) having clamping devices (11) arranged thereon for the workpieces. In order to be able to accept high working forces at the working stations (I-V) without danger of impairment of working accuracy, and to obtain good accessibility of the workpieces and of the tools of the machining units (14, 15, 16), the automatic transfer machine tool has a rigid cage (1) with two wall portions (2, 3) which are located opposite from each other and spaced from each other and rigidly interconnected, the upper wall portion (3) having the workpiece holder (10) rotatably journalled on the upper wall portion (3) within the interior of the cage, and the cage is seated with the lower wall portion (3) on the center post (8), the machining units (14, 15, 16) being inserted in the region of the respective separate working stations (I-V) in the cage (1).
