摘要： An ultrasonic vibration device has a sonotrode and a converter, the converter having a piezoelectric actuator for converting an electrical alternating voltage into a mechanical vibration. A first piezoelectric sensor element outputs a first measurement signal which varies in dependence on the vibration amplitude of the mechanical vibration. To permit measurement of at least one intensive state variable like the temperature, or the aging state of the piezoelectric actuator, a second piezoelectric sensor element outputs a second measurement signal which also varies in dependence on the vibration amplitude of the mechanical vibration. However, the second piezoelectric sensor element differs in a physical property from the first.

摘要： A shock absorber, for use with headgear having a faceguard, has a sliding member that does not extend beyond the support structure of the shock absorber in a way that would leave it vulnerable to damage. A headgear having a faceguard provides a protected mounting location for mounting a shock absorber for the faceguard.

摘要： The present invention relates to a method for ultrasonic treatment of a plastic material, comprising the steps of: positioning the plastic material between a sonotrode and a counter-tool, bringing the sonotrode excited by means of an ultrasonic oscillation into contact with the plastic material during a welding phase, moving the sonotrode and the counter-tool towards each other during a holding phase, in which neither the sonotrode nor the counter-tool are excited with an ultrasonic oscillation so that a force F is applied onto the plastic material. In order to reduce treatment times, wherein at the same time the quality of the welding process is not impaired but is even to be improved, it is proposed according to the invention that the force F is varied during the holding phase.

摘要： The invention concerns a dosing pump for moving a fluid, comprising a dosing head in which there is a dosing chamber and a displacement element reciprocatable between a first and a second position, wherein the displacement element delimits the dosing chamber, and the volume of the dosing chamber in the first position of the displacement element is greater than the volume of the dosing chamber in the second position of the displacement element, wherein the displacement element is coupled to a linear motor by way of a stroke element in such a way that in operation of the linear motor the stroke element performs a forward stroke and a return stroke in a housing in a direction of a movement axis with a stroke length h and the displacement element is reciprocated between the first position and the second position. To provide a dosing pump and to improve dosing pumps which are driven with a linear motor it is therefore proposed according to the invention that the stroke element has a cross-sectional area Q perpendicularly to the movement axis, wherein the square of the stroke length h is at least forty times greater than the cross-sectional area Q.

摘要： A diaphragm unit for a diaphragm pump includes a diaphragm core and a multi-layer pump diaphragm connected to the diaphragm core. The pump diaphragm has a fluid-impermeable working layer which comes into contact with a fluid to be delivered, and a fluid-impermeable safety layer. A sealed volume for receiving fluid passing through the working layer is arranged between the working layer and the safety layer. A first clamping region of the diaphragm forms a ring which annularly surrounds the diaphragm core. To detect a rupture of the working diaphragm layer, at least one element of a sensor is provided within the ring formed by the first clamping region for detecting fluid which penetrates into the sealed volume.

摘要： The present invention relates to a method for intermittent ultrasonic processing of a length of material, wherein a length of material is moved through between a sonotrode and a counter-tool and the length of material is processed intermittently. In order to specify a method for intermittent ultrasonic processing of a length of material by which the disadvantages of the prior art can be avoided or at least reduced, according to the invention it is suggested that in a processing interval the sonotrode is stimulated by an ultrasonic oscillation with an oscillation amplitude A and in a movement interval the sonotrode is stimulated with an oscillation amplitude B, wherein B

摘要： A method and apparatus is provided for water filtration of a milk of lime solution that contains water, impurities, and grit particles, in which the milk of lime solution enters a vessel, and wherein turbulence is created in the vessel, by which larger grit particles settle out of the milk of lime solution, to form a bed of grit particles in the lower end of the vessel, such that grit particles and impurities are filtered from the lime-treated water that comprises a milk of lime solution, with water then being drawn off, that may be discharged out one or more dosing locations and/or recycled back for further filtration, as may be desired.
