摘要:
The application relates to a microwave sensor for measuring a dielectric property, especially the density and/or moisture content of a product, having a microwave resonator, wherein a product introduced into the resonator interacts with a resonant microwave field generated in the resonator in order to determine suitable measured quantities, and is characterised in that at least two half-waves of the electric field are formed in the resonator in one direction, the product feed being effected in at least one region of high field intensity of one of the half-waves of the electric field.

The invention relates to a measuring arrangement for measuring the density of a product by means of microwaves. The measuring arrangement comprises a first microwave resonator, from which, in operation, microwaves enter a product area, and a device for compensating for environmental influences and disturbance variables affecting the measuring signal of the first microwave resonator. According to the invention, the compensation device comprises a second microwave resonator, which is shielded towards the product area with respect to microwave radiation.

An apparatus on a spinning machine for depositing fibre sliver. The apparatus comprises a delivery device comprising a coiler plate adapted to deliver fibre sliver in the form of a can-less fibre sliver package. The apparatus also comprises a substantially planar receiving support surface onto which the fibre sliver is deposited, the receiving support surface adapted to move back and forth in a deposition area with respect to the delivery device through a substantially horizontal stroke. The receiving support surface is also adapted to move away from the delivery device in a substantially vertical stroke during delivery of the fibre sliver. The delivery device and the receiving support surface are both adapted to remain in contact with the fibre sliver as it is deposited in the form of a can-less fibre sliver package, such that the fibre sliver package is stabilized during the substantially horizontal stroke and during lowering of the receiving support surface.

In an apparatus on a spinning room machine, especially a spinning preparation machine for depositing fibre sliver, in which there is a delivery device for delivering fibre sliver and a substantially planar receiving support surface for receiving and collecting the fibre sliver in the form of a can-less fibre sliver package, the receiving support surface being substantially unenclosed, the receiving support surface and the delivery device are displaceable relative to one another, the receiving support surface being movable back and forth horizontally. In order to effect simple discharge the fibre sliver package, together with the receiving support surface, is dischargeable from the machine, the fibre sliver package is removable from the receiving support surface and the receiving support surface is displaceable back into the machine.

A storage device, for example a belt storage means, is provided for receiving at least one fibre sliver package, in which the at least one fibre sliver package is stably positionable.
摘要:
A microwave resonator for or on a textile machine, especially a card, draw frame, combing machine or the like, for attachment to a measuring device for measuring the mass and/or moisture content of textile fiber material conveyable continuously through a resonator chamber, has a housing with wall elements, wherein through-openings in spaced wall elements lying opposite one another are coaxially connected by a tubular element and the interior space of the housing is hollow. In order substantially to simplify manufacture and permit an uninterrupted resonance field, the housing comprises a hollow profile with profile walls in which at least one tubular element connects through-openings in opposite profile walls with each other.
