摘要:
A method for detecting impermissible operating states in electronically controlled tumble dryers, in particular the state of motion of a laundry drum. In the method, the electrical conductivity of the laundry is determined by electrodes which touch the laundry, at least from time to time. The method is distinguished by the fact that, during the drying operation, the conductivity is periodically measured. The currently measured conductivity value is compared with at least one previously measured conductivity value and, if changes in conductivity that are determined from the compared values over a multi-period interval corresponds to a preset low range of fluctuation, an indication is given that the laundry drum is stationary.

Disclosed is a medical instrument for treating biological tissue, comprising a device generating extracorporeal pressure waves and a transmission element (2) coupling said pressure waves into the body of living beings. The pressure wave is generated by a stroking member (10) impacting on a transmission element (2) and is transmitted inside the transmission element. Said transmission element comprises a boundary surface at the outlet thereof, which is curved towards the inside and is configured such that the pressure waves can be coupled into the biological tissue and can be focused therein.

A thermal trip unit within a multi-pole circuit breaker includes a bimetal element having an off-set end to provide cam function during the calibration of the bimetal element. A calibration screw is threadingly engaged within the bimetal element and is adjusted at various calibration levels by means of a step motor driver element.
摘要:
An ejection apparatus for the high pressure ejection of a liquid. The apparatus has the following elements: (a) a pressure chamber for containing the liquid; (b) an ejection opening communicating between an outside and an inside of the pressure chamber; (c) a working piston displaceable in the pressure chamber from a first position at a beginning of a working stroke to second position at an end of the working stroke, having (1) a first end defining a first volume within the pressure chamber when the working piston is at the first position and displacing a second volume, less than the first volume, when the working piston moves from the first position to the second position, and (2) having a second end distal from the first end; and (d) a drive for driving the working piston including (1) an impact member for elastically impacting the second end of the working piston to cause the working piston from the first to the second position and (2) means for accelerating the impact member to impact the working piston. The device can be constructed either as an endoscopic device for delivering liquids in minimally invasive surgical procedures, or as a needle-less inoculation device.

A drill chuck includes clamping jaws guided in openings inclined toward each other in a chuck body and displaced via a manually rotatable clamping sleeve and a blocking sleeve, which is axially displaceable and partially rotated in relation to the chuck body. The blocking sleeve can be connected with the clamping sleeve by being displaced into its axial end position. A spring operating in the circumferential direction between the chuck body and the blocking sleeve, which prestresses the blocking sleeve in relation to the chuck body in a direction corresponding to the closing direction of the clamping sleeve is provided. To increase the service life of the drill chuck it is embodied in such a way that the end of the spring on the blocking sleeve side is disposed on a plate- or disk-shaped adjusting disk which encloses the shaft of the chuck body, is interlockingly taken along with the rotation of the blocking sleeve and is axially displaceable on the blocking sleeve, and in such a way that, for limiting the rotation of the blocking sleeve in relation to the chuck body, a cam is provided, which operates between the surface of the shaft of the chuck body and the adjusting disk and is limited by two detents.
摘要:
In a quick-action clamping device for axially securing a disk-shaped tool, particularly a grinding wheel on a flange of a driven spindle that has a clamping part provided with a thread that can be screwed to the thread of the spindle. The disk-shaped tool is held clamped between contact surfaces of the flange and the clamping part whose spacing from one another can be changed. It is proposed to avoid complete release of the tension nut during spindle stop operation in that the tool is pressed against the flange by means of at least one additional holding surface via a spring force, and that this additional holding surface is connected to the spindle in a manner secured against relative rotation.
