Method and thermal analysis device including a sample holder and at least one temperature detector which is assigned to the holder. The invention further relates to a production method for a temperature detector. A heat flow to be detected is conveyed to the temperature detector between a support surface and the sample holder, wherein the support surface and/or the sample holder include elevations or depressions forming contact points, which define a relevant heat flow zone assigned to the support surface. A thermocouple, which includes at least two elements made of different metals, a first metallic element A, with a higher expansion coefficient compared to a second metallic element B, is introduced in a precisely fitting manner into second metallic element B constituted as a hollow profile and the two elements A, B are heated in a first operational step and then cooled again in a second operational step.

Method and device for material analysis

A screw spindle pump for the delivery of fluid media with a pump housing having an inlet channel with a first longitudinal axis, an outlet channel with a second longitudinal axis, a first drive spindle with a third longitudinal axis, and a second driven spindle. The spindles each include a profiled section between the inlet channel and the outlet channel, wherein the profiled sections of the spindles are engaged at least partially with one another and form, with the pump housing between the inlet channel and the outlet channel, a delivery section parallel to the longitudinal axis of the drive spindle with delivery chambers for the fluid medium. The second longitudinal axis of the outlet channel is disposed at an obtuse angle to the delivery section in the pump housing. The invention also relates to a method for operating a screw spindle pump.

Screw pump

A method for evaluating a measurement result of a thermal analysis. A program-controlled computer unit is used to calculate at least one probability of the agreement of the measurement result with at least one dataset previously stored in the computer unit, wherein this calculation is based on a comparison of effect data previously extracted from a measurement curve of the thermal analysis with corresponding stored effect data of the dataset. The evaluation can advantageously include, an automatic recognition and classification of measurement curves and can be carried out in particular more efficiently, more economically and more quickly than previously, with at the same time a high quality of evaluation.

A screw spindle pump constituted by at least two parts is disclosed. The first part includes a housing and at least one spindle system disposed in the housing and capable of being driven in a rotational manner. Furthermore, a pressure region disposed downstream of the spindle system and at least one outlet opening which is connected to the pressure region, the outlet opening discharging the delivery medium out of the pressure region. The second part includes at least one low-pressure chamber disposed upstream of the spindle system and at least one inlet opening for the delivery medium into the low-pressure chamber. The first part and the second part are coupled together, preferably in a rotational manner, so that they can assume at least two different relative positions.

A rotary piston pump for the delivery of liquids and for the delivery of liquids containing solids. The rotary piston pump includes a pump housing which is provided with an inlet and an outlet. The pump housing includes a lining. Disposed in the pump housing, or inside the lining, are at least two counter-rotating rotary pistons, which form pump spaces during their rotation. During the rotational movement, the rotary pistons are sealed against one another, against the pump housing and against the lining. Disposed in the pump housing and/or in the lining, in the spatial vicinity of the inlet and/or the outlet, are means with which the pulsation can be reduced or even completely prevented.

Rotary piston pump with optimised inlets and outlets

A rotary piston pump with at least two double- or multi-lobe rotary pistons rotating in opposite directions, the drive shafts whereof include seals, wherein the seals are constituted as slip ring seals or lip seals or stuffing-box seals, which in each case are disposed on the shaft shoulder belonging to the respective rotary piston, and one slip ring per seal is provided with a locking device, which includes a large number of fixing positions. The seals are pushed onto a tubular shoulder of the rotary piston, the rotary piston is introduced into the pump housing, the securing element is connected to the slip ring seal in a form-fit manner by rotation of the rotary piston and the shaft shoulder is then rigidly connected to the drive shaft.

Rotary piston pump with slip ring seals for improved fitting and synchronization of rotary pistons

A method and a device for fixing and synchronizing rotary pistons in a rotary piston pump involves introducing the rotary pistons into the pump space of the rotary piston pump. A shaft stub of each rotary piston is then pushed through a pump rear wall onto a driveshaft provided for the respective rotary piston. The rotary pistons are aligned and synchronized in the pump space via a template, the template being fixed detachably to a pump housing. The shaft stubs of the respective rotary piston are connected, after the synchronization, in each case via a clamping device in a friction-locked manner to the respective driveshaft, outside the pump space.

An intake filter for an internal combustion engine for a motor vehicle including an unfiltered air intake region, a filter medium and a filtered air conduit, in which the unfiltered air intake region is arranged beneath the engine hood of the motor vehicle and is attached to the engine hood. The filter medium is tubular body which has a porosity that ensures a sufficient filtration of the intake air for the internal combustion engine.

A parking brake for a commercial vehicle equipped with an air-operated service brake is configured in such a way that the actuating energy for the brake is reduced in comparison to a configuration with a spring brake cylinder, while the installation space in the wheel area is minimized. Primary functional parts of the parking brake include an inner race and an outer race, which delimit an annular gap. Displaceable tapered-roller bearings are located in the annular gap. To adopt a release position in opposition to the action of a compression spring, the tapered roller bearings are disengaged from the conical surfaces of the inner race and the outer race.

The present invention relates to the arrangement of a stator and a spare stator. In order to avoid a permanent correction in the length of the driving shaft, the spare stator is connected to the instantaneously operated stator or is configured in a single piece. Upon occurrence of a defined amount of wear, this stator combination is merely reversed through 180&#xb0; relative to the longitudinal axis or an intermediate tube is inserted so that the spare stator arrives in the rotor region.

The invention is directed to a shaving foil for a shaving system of a shaving apparatus, in which the shaving foil cooperates with an undercutter adapted to be driven relative to the shaving foil. The shaving foil includes a perforate region comprised of a plurality of hair-receiving apertures, wherein said apertures form a quasi-periodic pattern executed in accordance with a Penrose parquet.

A shaving system for a dry shaver has at least one long-hair cutter arranged between shaving units for short-hair cutting. The shaving units for short-hair cutting each include an upper blade and a lower blade, which can be moved relative to one another by a drive. The long-hair cutter is formed from at least two cutting elements that can be moved relative to one another and are arranged one beside the other. The cutting elements of the long-hair cutter are each of comb-like design, and their rows of cutting teeth, which are formed by tines, are oriented essentially perpendicularly to the skin which is to be shaved.
