  • Patent number: 11883938
    Abstract: A handheld setting tool for driving a nail or bolt into a substrate, comprising: a drive, preferably a gas spring drive or an electrodynamic drive, which drives an actuator, which actuator is used to drive the nail or bolt into the substrate; characterised by: a decoupling device which at least partially decouples a first movement process of a first moving part or piston in the actuator, driven by the drive, from a second movement process of a second moving part or piston in the actuator so as to drive the nail or bolt into the substrate.

  • Patent number: 11495380
    Abstract: A bistable hoisting solenoid comprising first and second stroke end position and a stroke center position, comprising: a stator, one or more armatures, at least one coil, at least one permanent magnet and a spring system having a first spring which, in the first stroke end position, exerts a force in the direction of the stroke center position on the one or more armatures, and a second spring which, in the second stroke end position, exerts a force in the direction of the stroke center position on the one or more armatures. The one or more armatures, in the event of a loss of current, are held by permanent magnets in both stroke end positions. The first and the second springs have different paths with different lengths and/or exert in the respective stroke end position different sized forces on the one or more armatures and/or have different sized spring rates.

  • Patent number: 10994946
    Abstract: The present invention relates to an electromagnetic stopper for stopping and/or separating out cargo carriers and/or cargo conveyed on a continuously operated cargo conveyor system, comprising: a bistable solenoid having at least one coil and at least one permanent magnet; a cam, which can be retracted and extended with the aid of the solenoid, one or more electrical energy stores, in particular capacitors, a controller, which, with the aid of switches, discharges the energy store(s) via the at least one coil of the solenoid such that the cam is extended.

  • Patent number: 10522313
    Abstract: A reversing linear solenoid polarized in a permanent magnetic manner having a first and second end stroke position as well as at least one armature, wherein it has a spring system or is operated at such a spring system which exerts a force in the direction of the center stroke position on the armature or armatures in the end stroke position(s). The spring system and the reversing linear solenoid are coordinated with one another such that the armature or armatures are held in a permanent magnetic manner against the spring force in both end stroke positions. The spring system is configured such that the potential energy (elastically) stored by movement of the armature or armatures into its/their end stroke movements is of equal magnitude. If external restoring forces caused by the application are present, they must be taken into account in the design of the spring system.

  • Patent number: 9953786
    Abstract: A self-holding magnet has a spring (accumulator spring) and a first armature. The self-holding magnet is capable of holding the first magnet armature against the spring force in a lift position which is determined by a stop. The stop determines a remaining air gap of a working air gap. The magnetic circuit of the self-holding magnet has a magnetic shunt with particularly low reluctance of the same order of magnitude as a series reluctance of the remaining working air gap(s). The working air gap(s) and the shunt are magnetically connected in parallel with the flow generated by a permanent magnet but in series with the flow generated by the trigger coil. The self-holding magnet additionally has at least one positive feedback device such as a compressible resilient stop or a shunt.
