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.

摘要： A peristaltic pump includes a casing having a bottom, cover and wall forming a pump chamber, a tube connecting a casing inlet to a casing outlet arranged within the pump chamber, and a displacement element having at least two displacement members. The tube is arranged between the casing wall and the displacement element in such a way that due to rotation of the rotor the displacement members roll on the tube so the tube is squashed together so that a medium to be conveyed which is in the tube is displaced in the direction of the casing outlet. The displacement element has a first part fixed to the rotor and a second part which can be reciprocated between an operative position and a change position.

摘要： Invention relating to a method for controlling an ultrasonic machining, in which an ultrasonic vibration is transmitted via a sonotrode into the material to be machined. During the first machining interval, a first welding variable of the group S, consisting of the frequency f and the amplitude ü of the ultrasonic vibration, the force F, which the sonotrode exerts on the material to be machined, the power P, which the generator delivers, and the speed v, with which the sonotrode is moved in the direction of the material to be machined, is kept constant until a first target variable of the group Z adopts a predetermined value. During an adjoining second machining interval, a second welding variable of the group S is kept constant until a second target variable of the group Z adopts a predetermined value, wherein the first and the second target variable differ.

摘要： A telescopic slide for a microwave oven has a first slide element and a second slide element each having two running surfaces with caged rolling bodies arranged on the running surfaces. The slide elements can be moved along against each other between a retracted position and an extended position. The slide elements each have at least one electrically conductive contact element arranged on the slide elements in such a way that in the retracted position either the contact elements are directly in engagement or that the contact element of the first slide element and the contact element of the second slide element are each in engagement with an electrically conducting conductive element that is moved concomitantly with the rolling-body cage. The result is that in the retracted position there is an electrically conducting connection between the first and the second slide elements, and in at least one position other than the retracted position the electrically conducting connection is broken.
