Abstract: An electric drive motor for a pump includes an electrically actuatable stator winding, and a rotor which is mounted for rotation in a field of the stator winding in the presence of an annular gap. The rotor includes a motor shaft, a magnet carrier disposed on the motor shaft, and at least one permanent magnet arranged on the magnet carrier. The magnet carrier is made from a ferromagnetic chrome steel.

Abstract: Continuous casting moulds used in automated installations casting metal melts into strands require comprehensive, reliable real-time monitoring. Currently used systems are susceptible to damage and limited to just a few sensors, as arrangements involving a higher number of sensors have proven impractical due to the substantial effort they cause when exchanging a mould. To overcome this obstacle it is suggested to use wirelessly interrogable passive surface acoustic wave (SAW) sensors for monitoring of physical parameters in continuous casting moulds, and install at least one wireless link section in the signal path between SAW sensors and their reader devices. Continuous casting moulds thus become easily exchangeable with their sensors installed, making it industrially practicable to equip continuous casting moulds with a significantly higher number of sensors than previously feasible.

Abstract: The invention relates to an internal combustion engine with a laser ignition device (1), Q-switched, pumped solid-state laser with a pulsed pumped light source (30), a solid laser crystal (2), enclosed in a resonator, a Q-switch (4), for increasing the power density, at least one output mirror (6) and a focussing device (7), by means of which the laser beam (26) may be focussed in a combustion chamber.

Abstract: A stator end disk is provided for a laminated stator core of a commutator motor, especially a universal motor, especially for use in a domestic appliance. The stator end disk contains a connecting terminal having connecting elements for connecting stator winding wires and a female connector with contact elements for receiving and electrically connecting to an external motor connector. All of the connecting elements are connected to one associated contact element each so as to be electrically conducting. Only one connecting terminal is disposed on the stator end disk. In order to electrically contact at least one further internal, electrical component of the commutator motor, at least one additional contact element associated with the component is disposed in the female connector.

Abstract: For especially simple and reliable handling of thin and/or bent semiconductor wafers it is proposed in a corresponding holding means (100) that there is a gas flowing through at least one first means (5) for producing the forces which pull a semiconductor wafer toward the means (100) based on the Bernoulli principle and that there is at least one second means (2, 3) for holding the semiconductor wafer on the means (100) as a result of the forces produced by at least one electromagnetic field.

Abstract: A device for pressing out and dispensing dosed quantities of flowable multi-component compounds by application of a pressure on flexible bags for the different components comprising a housing with at least two receiving spaces for the flexible bags, the end of which can be closed by a removable cover element, two plunger-like inserts guided for sliding movement in the receiving spaces, for exerting the pressure on the flexible bags, a mixing device equipped with an ejection nozzle and a drive unit comprising an electric motor and a drive spindle, which drives both the plunger-like inserts and the mixing device, is characterized by the fact that the two receiving spaces open into a mixing space accommodating the mixing device and formed in the cover element.

Abstract: An apparatus for extrusion and metered delivery of free-flowing substances, having a housing (11); having a receiving space (12), openable at least on one side, for a disposable material package; having an expulsion nozzle (13); having a compressed-air connection; and having, on the side opposite the expulsion nozzle (13), a piston that is displaceable in the direction of the expulsion nozzle (13) in the receiving space (12) or in the disposable material package, and pushes the substance ahead of it and thereby ejects it from the expulsion nozzle (13), compressed air being fed from the compressed-air connection to the side of the piston facing away from the expulsion nozzle (13), is characterized in that a compressor (30) driven by an electric motor (20) is arranged in/on the housing (11) in order to generate the compressed air.

Abstract: In the case of a universal electric motor for any kind of drive, with a stator package, a rotatably mounted rotor with commutator, as well as end shields on both sides that also constitute the bearings for the rotor and a switching ring that can be rotated through predetermined angular amounts and carries the (carbon) brushes, it is proposed to insert into the end shield A a closely fitting anchor block that serves for locking together the two end shields with the intervening stator package; further, the switching ring can be mounted on an external annular end face of the end shield B that also carries the switching strips or switching rails needed for switching between clockwise and counter clockwise rotation, complete with contact areas situated in the plane of the annular end face and suitable for axial contacting, the said contact areas making contact with other axial contact areas on the switching ring to establish connections with the carbon brushes.

Abstract: For the purposes of assembling an electric tool, and especially an electric hand tool such as, for example, a hand drill, a grinder or a sabre saw, it is proposed to use modular components that are to be axially inserted into and connected with each other. The components comprise a self-contained electric driving motor that supports the rotor shaft in a centered position by means of end shields on both sides that are rigidly fixed to the stator, a self-contained gearing head that is fixed to the motor, and at least a partially tubular, single piece main housing that accommodates the driving motor and the gearing head, an electric circuitry module inserted into the main housing, and a rear cover for the housing.

Abstract: It is proposed to obtain a switching device for the electrical switching (i.e. switching on and off or reversing the direction of rotation) of electric tools, especially electric hand tools such as drills, grinders and the like, by mounting a rotatable setting ring on the outer cylindrical housing of the electric tool and positioning it opposite the end shield at the B-end of the electric motor inside the housing in such a manner that inwardly pointing projections of the setting ring will grip a plate or switching ring on the electric motor and will cause the said plate or switching ring to perform a slave motion for switching the electric motor on and off or reversing its direction of rotation whenever the external setting ring is subjected to a manual rotation.

Abstract: A method and apparatus for controlling an electric motor, in particular a motor for driving hand tools, saws, and the like, the rotational speed of which is automatically reduced in no-load idling operation and increased when working under load to pre-determined speed values corresponding to desired working speeds. A current sensor picks up the current absorbed by the electric motor and causes the speed of the electric motor to be abruptly changed when a load condition has been detected. A timing relay maintains the electric motor at the higher working speed for a pre-determined period of time after termination of the operation under load. The threshold value of the sensitivity of the current sensor is raised simultaneously with the change-over to the higher working speed.
