Abstract: The invention relates to a suction/rinsing instrument comprising a suction channel for removing fluid and a rinsing channel for supplying rinsing fluid. The suction channel is provided for receiving an auxiliary instrument. Via a grip part of the instrument, the auxiliary instrument, for example a forceps, may be controlled. The auxiliary instrument is fixed on the suction/rinsing instrument by way of a receiver. The receiver can be traversed in the axial direction of the shank, the traversing is effected via operating means provided on or near the grip part, so that the operator, without having to let go of the grip part, may selectively, with only one hand, push forward the auxiliary instrument an thus operate or also retract the auxiliary instrument and clear the suction/rinsing channel.

Abstract: An apparatus (10) for intraoperative calibration of a fundus fold cuff comprises an inlet having lead (14) the end of which facing the patient being connectable to an inflatable balloon (13) and the other end of which facing away from the patient having means for inflation/deflation of the balloon 13 and for measurement of the internal pressure of the balloon (13). The balloon (13) has, at least in the inflated state, an outer contour defining a seating surface (16) and two raised humps (17) which are sidewardly bordered. Fundus portions are joined together to form a cuff surrounding the esophagus, and the properties of the cuff are determined by the forces exercised by the cuff on the balloon.

Abstract: A seal 10 comprises a bushing 11 and a thread 12, wherein the bushing 11 has a first lumen 15 and a second lumen 16. The lumina 15 and 16 extend along the entire length of the bushing 11. The thread 12 can be introduced at one end into the second lumen 16 and has a swelling 21 at the free end which prevents reintroduction and travel of the end of the thread through the second lumen 16. The thread 12 can be introduced into the first lumen 15 via its other free end and pushed through first lumen 15. Enlargements 20 are formed on the thread 12 having a size preventing introduction into the first lumen 15 without the exercise of force. The bushing 11 and the thread 12 are manufactured from a flexible material having a stable shape. When the enlargements 20 are pulled into the first lumen 15, the bushing 11 bends and seats on e.g. tissue to be ligated. When the enlargements 20 are completely pulled into the first lumen 15, the seal 10 is permanently closed.

Abstract: The invention relates to new fluorine-containing macrocyclic metal complexes that consist of a complexing agent of formula I and at least one metal ion of an element of atomic numbers 21-29, 42, 44 or 57-83 ##STR1## in which n, R.sup.1, R.sup.2, R.sup.3 and A have a different meaning, agents containing these compounds, their use as NMR and x-ray diagnostic agents as well as process for the production of these compounds and agents.

Abstract: A process for the manufacture of a surface element in the form of a lamellar mat or sheet which can be used for the absorption of electromagnetic waves, in particularly radar waves. The surface element has a plurality of bands of mineral wool separated by bands of an electrically-conducting material and is manufactured on an industrial scale by stacking several mineral wool strips, sheets, or mats with intermediate layers of the electrically-conducting strips, sheets or mats into a pile. From this pile are then cut out pads composed of different bands which are laid out in such way that their cut faces become the large surface areas of the surface element. Then, each of the surface elements is clad on at least one face with a backing strip, for example of meshed aluminum foil, the main orientation of the fibers of the mineral wool being perpendicular to the backing strip.

Abstract: Bracing strips 7 are interposed between compressible strips 4, so-called laminate strips, of an insulating mat 1 in the form of a laminate mat with a carrier web 2, in order generally to impart compression resistance to the insulating mat 1. The compressible strips 4 normally consist of mineral fibers 6 of low compression resistance and are readily compressible parallel with the plane of the carrier web 2, while the bracing strips 7 consist of mineral fibers of higher compression strength and are substantially incompressible. Particularly good compression strength results from the fibers 8 of the bracing strips 7 also being orientated at right-angles to the carrier web 2. The resulting pressure-resistant laminate insulating mats 1 are suitable not only for the conventional fields of application of laminate mats but can also serve at the same time as a bracing since in many cases they offer superior qualities to those of supports or braces which consist of solid bodies.

Abstract: Disclosed is a mitering gauge for cutting pipe shaped members, the gauge including a console and at least one upright side member having an oblique end face for guiding a cutting tool. The mitering gauge provides both guidance of the cutting tool and guidance of the member to be cut.

Abstract: Conductive structures in polymers are obtained by a method in which poly(organylheteroacetylenes) of formula I ##STR1## or a mixture of poly(organylheteroacetylenes) of formula I and other polymers are exposed to radiation of high energy density, preferably laser radiation. At relatively low temperatures of 100.degree. C. to 600.degree. C., the polymer structure is effected so that electrically conductive structures result. The products are employed in electrical engineering, electronics and microelectronics, preferably as printed conductors. The invention makes it possible to inscribe long-term stable, conductive structures in an insulating polymer matrix in a one-step method, it being possible to use modern computer techniques (computer graphics)and to produce computer-aided conductor structures directly. The polymers can be used without supports or applied on rigid or flexible materials.

Abstract: A liquid-liquid two-phase extraction process in which a feed solution is introduced into an intermediate stage of a multistage extraction apparatus. The solution is water and one or more valuable material to be recovered by extraction. An organic extractant is introduced into one end of the apparatus. The extractant is a solvent and flows through the apparatus. The valuable material is extracted from the feed solution to provide a charged organic phase. An aqueous extractant having water is introduced into another end of the apparatus to wash the charged organic phase. The aqueous extractant flows through the multistate extraction apparatus countercurrent to the extractant and contributes to the aqueous phase. The organic extractant is divided into at least two streams prior to introducing the organic extractant into the apparatus. Each stream is introduced into the apparatus at different stages, both ahead of the intermediate stage.
