  • Patent number: 6409915
    Abstract: A rake cleaning arrangement for a trashrack situated in front of the intake opening of a turbine arrangement, wherein the turbine arrangement is arranged in a weir opening delimited at its sides by two pillars and these pillars delimiting the weir opening are spanned by at least one gangway forming a service platform, comprises a bridge forming a service platform which can be lowered into the weir opening by a crane arranged on top of or on the gangway, and a skimming arrangement for removing flotsam from the trashrack by which a tool can travel along the vertical extent of the trashrack and which is arranged on the bridge, wherein the tool can travel along the vertical extent of the trashrack by the skimming arrangement when the bridge is stationary.

  • Patent number: 4963129
    Abstract: Prior-art systems for drainage of body cavities, in particular renal cavity systems, have usually comprised of a flexible drainage tube (1) with at least one crooked end (11, 13), a tubular device, called a pusher (2), serving to push the drainage tube (1) into a body cavity, a distal end of which is connected in a separable way with a proximal end of the drainage tube (1), and a guide wire (3) passing through the drainage tube (1) and the pusher (2). Up to now, the separable connection consisted of either a predetermined break point or a wedge connection. Both solutions have been unsatisfactory.According to this invention, ends of a drainage tube (1) and a pusher (2), which are connected with each other, have parts (41, 42) of a lock (4) complementary to each other, which define sections (45, 46) overlapping each other and featuring facing sections fitted to each other which transmit axial traction forces and a torque. Sections (45, 46) are held in mesh by the guide wire (3) passing through them.

  • Patent number: 4279251
    Abstract: In a tube for the enteral introduction or aspiration of gases or liquids, in particular for the enteral alimentation of patients, a weighting means is affixed in the introduction end section, the said weighting means being formed of a capsule (8) which is insoluble in the stomach, but soluble in the region of the intestine. In this manner, the tubing forming the tube can be very thin.

  • Patent number: 4265848
    Abstract: The invention relates to a method for the production of a medical instrument, in particular a tube or catheter, with a balloon made of an elastomeric and/or thermoplastic material, comprising the steps of providing an inflation line for the balloon on or in one hose section and applying thereafter the cuff-shaped balloon with its two ends closely fitting and overlapping one outlet of the said inflation line. To render the production economical, a coat (3) of a parting compound is applied to the hose section (1) in the area where the balloon (10) is to be formed, whereafter the hose is sheathed by extrusion with a sheathing coat (5) of a thermoplastic or elastomeric material.
