Abstract: A pipeline or measuring tube having at least one insulating layer, at least in certain regions, and comprising, manufactured in a primary shaping method, a tubular element, which has an otherwise closed structure and which has at least one region with an open-pored, cellular structure, wherein the material of the insulating layer, in the applying of the insulating layer, can penetrate into the pores of the open-pored, cellular structure of the tubular element and the insulating layer has on the side to be insulated a closed, homogeneous structure.

Abstract: A measuring transducer including a measuring tube for conveying a fluid; a measuring electrode arrangement for registering electric voltages produced in the flowing fluid; as well as a magnetic field system situated externally on the measuring tube for producing a magnetic field at least partially passing through the measuring tube as well as the therein conveyed fluid during operation, for inducing an electric field in the flowing fluid, wherein the magnetic field system has at least one field coil, through which an electrical exciter current flows at least at times during operation. A coil holder is also including serving for holding the at least one field coil externally on the measuring tube, wherein the measuring tube and coil holder are connected joint-freely with one another, so that the coil holder is embodied as an integral component of the measuring tube.

Abstract: A compound needle for a knitting machine has a machine shank of substantially rectangular cross section, in which a substantially U-shaped longitudinal groove open at the top is formed. A closing slider adapted to fit the cross section of the groove is guided in the groove in a longitudinally slidable manner, and the groove has at least one slit leading to the outside, which extends parallel to the longitudinal axis of the groove.In order to attain satisfactory removal of fluff or lint from the longitudinal groove, on the one hand, and to assure sufficient stability and resistance to transverse bending of the needle on the other, the longitudinal groove is closed on its top, at least partially, in the vicinity of the recess by means of a rib which also forms a guide for the slider.

Abstract: A stamped knitting tool for knitting machines, for instance a latch needle, compound needle, bearded needle, plush hook or the like, has a hook formed on a stem with an intermediate neck, the hook being entirely made of a profiled material of substantially rectangular cross section, up to the end of the hook or the beginning of a hook point embodied there.In order to assure that the hook is capable of withstanding the great stresses occurring during the knitting process without the danger of premature breakage or bending open of the hook or other damage while keeping the hook at an appropriately small size, the hook (5), beginning at a maximum value (3) of the cross-sectional dimensions close to the neck (4), formed with steadily decreasing tapering cross-sectional dimensions from the vicinity of the neck (4) toward the end of the hook or the region of the beginning of the hook point (9).

Abstract: A latch needle for machines for producing knitted goods has a needle shank, a needle head and a latch which is pivotably supported in a latch slot.In order to assure that even after long use the latch will close satisfactorily, and will not come to rest beside or underneath the needle head when closing, the latch spoon (8) is tilted with respect to the plane of symmetry (10) of the latch (5), pointing toward one side of the needle shank (1); the lateral distance (A) from the most extreme point (11) of the latch spoon (8) to the plane of symmetry (12) of the needle is equal to not more than half the shank thickness.
