摘要:
A device for adjusting the trigger weight of a revolver having a return spring and thrust rod acting on the trigger. The thrust rod has one end which is articulately connected to the trigger and another end which capable of being adjustably positioned such that the angular position of the thrust rod with respect to the trigger is variable.

The invention relates to an inductance coil, in particular an inductance coil without an iron core for use in electric power grids, comprising at least two cylindrical winding layers (1), which are disposed concentrically with respect to a coil central axis (7) and are connected electrically in parallel. The inductance coil comprises at least one means for reducing or minimizing sound emissions produced during the operation of the inductance coil. At least the outermost winding layer (1) is designed in this case as a current-conducting, acoustic shield winding (18) opposite the winding layer (1) adjacent in the direction of the coil central axis (7), wherein the shield winding (18) is dimensioned electrically such that it is designed for the transmission of a current intensity, which is only a fraction of the current intensity, to be transmitted by the adjacent winding layer (1). Furthermore, the invention relates to a bracket-like holding element arranged on at least one end face of the inductance coil for reducing sound emissions.

An apparatus for controlling an AC-motor, with a feedback arrangement in which the feed-back signal is the output signal of a partly mechanical pulse generator coupled to the shaft of the motor, comprising a micro-processor to which is fed a feed-back signal and a reference signal and a digital clock which sends output signals to said micro-processor, said micro-processor generating signals through a first set of output controls for controlling the frequency and phase of the AC-power supplied to the motor by comparing the reference signal and the arrival times of the feed-back pulses as indicated by the digital clock.
摘要:
In a method for measuring a distance between a conducting reaction track and a functional surface moving relative to the reaction track a sensor with two signal transmitters is provided on the functional surface. An alternating field is generated in the sensor. The alternating field changes as a function of the distance between the conducting reaction track and the functional surface. Each of the two signal transmitters detects the changes of the alternating field as distance information. Each signal transmitter produces decoupled distance information values. These decoupled distance information values are processed in separate distance measuring channels to provide processed signals. The processed signals are constantly fed to and compared in a comparator. A distance information signal is emitted only when the processed signals of the separate distance measuring channels are identical within a predetermined tolerance range.

In a firearm having a barrel for receiving a cartridge, a firing pin having forward and rear ends and being movable between a cartridge-engaging firing position and an at-rest position and a trigger movable toward a firing position, an improved movable locking device for preventing movement of the firing pin to its firing position and, in response to movement of the trigger toward a firing position, for releasing said firing pin, said locking device being mounted in said barrel for movement between a locking position in which said device blocks movement of said firing pin to its firing position and an unlocking position in which said device is out of locking contact with said firing pin.
