A method for the selective elevation and separation of tissues comprised of multiple layers and a surgical instrument for performing the method. The method may be performed without the requirement of a solid mechanical device insertion or transection through the mucosal layer. In particular, the method and surgical instrument may be used for the selected separation and / or resection of selected portions of benign or malignant tissues (e.g. defining tissue planes, polyp elevation and removal, submucosal tissue tunneling, endoscopic mucosa resection, etc).

The joint (36) comprises a tubular body (37) having two connecting zones (38, 39) each connected by an end to a tubular element (40) of a fluid transport line, giving continuity to passage of fluid. The tubular body is made of a mixture of an electrically-conductive material such as PVC, with carbon black to give it electrical conductivity. The joint has an internal surface (41) which is destined to come into contact with the transported fluid, and an external surface which is destined to have a grounded galvanic contact. The joint is inserted in the discharge fluid drainage line of a dialyzer filter, in an apparatus for intensive treatment of acute renal insufficiency, for eliminating ECG artefacts due to functioning of peristaltic pumps in the apparatus.

The present invention relates to a packaging machine which has transport means in the form of two transport chains (5, 6) for lateral grasping and transporting of a length of material (7) consisting of packaging material. In particular with longer plants above approximately 10 meters in transport length the stretching property of the transport chains owing to the load has a marked effect on the precision of the transport distance. This results in fluctuations of the transport distance between the two transport chains and therefore distortions of the length of material, which, depending on the type of packaging material, can even lead to tearing of the length of material. In order to minimize these fluctuations, the first transport means (5) has a first engagement element (10) engaging in the first transport means (5) and the second transport means (6) a second engagement element (11) engaging in the second transport means (6), the first engagement element (10) being coupled to the second engagement element (11) in such a way that the two engagement elements are synchronized.

A corrosion-resistant tension member, particularly an inclined cable of a cable stayed bridge, is comprised of a bundle of individual elements, for example, steel wire strands, which in its open area is encapsulated by sheathing, and which within the structure extends inside a guide canal that is formed by a recess pipe. The sheathing—sealing off the front side of the guide canal—is thereby directly or indirectly connected to the structure. Between the sheathing and the entrance point of the tension member into the structure, a connecting pipe is arranged, which on the one hand is detachably connected to the sheathing and on the other hand is connected to the structure by a flange plate.

Power LEDs are implanted in a specially designed printed circuit board (PCB) that is known in the art as a Metal Core Printed Circuit Board (MCPCB). The MCPCB is bended over to so as to have rounded corners having a radius that is not smaller than a determined value depending of the overall thickness of the MCPCB and other factors without any negative effects on the insulating layer and copper traces in the area of bending. In this manner, the surface area of the heat sink used in an LED nail care curing appliance is increased. The MCPCB with installed LEDs with rounded corners thereby follows the natural curvature (based on the shape of a human hand) of the appliance housing, eliminating the need for additional heat sinks or fans to reduce the heat generated by the LEDs.

An optical rotary angle sensor with at least one first measurement member able to move in the measuring direction having light-transparent and non-transparent regions located on it, at least one second measurement member arranged static relative to the first measurement member in the measuring direction, and / or at least one photoelectric transducer. To keep the distance between the rotating measurement member and the static measurement member and / or the optical-electrical transducer very small, i.e. in the range of about 10–20 μm, and to make the centering of the two relative to each other independent of the formerly necessary shaft bearing, the measurement members are configured so that they are properly oriented relative to each other in the measuring direction and kept spaced apart by a guide provided between the measurement members. The guide can be a form-fitting connection in at least one of the directions not representing the measurement direction.

The invention relates to a process for disintegrating compressed bales of coarse, fiberlike, natural or synthetic materials, especially straw bales, and transporting the disintegrated materials to further processing. Bales often contain foreign objects which the invention removes from disintegrated bale material by moving the material disintegrated from the compressed bales to a feeding and collecting auger and sucking off the portions of natural or synthetic fiber intended for further processing from the feeding and collecting auger, while the contaminants collected are moved on by the feeding and collecting auger and discharged.
