Abstract: In order to thread a web material in a converting machine a system is provided, with a first continuous flexible member and a second flexible member. An anchoring element, to which there can be fixed the web material leading edge, may be transferred from one to the other of the two flexible members so as to facilitate the threading operations.

Abstract: An emptying unit for recovering bottom residue, particularly in drying filters, drying units and the like, comprising, inside a container for treating and containing dried product, fluid introducing elements for moving the bottom residue of the dried product. A discharge port being also provided which is controlled by a discharge valve interposed on a pneumatic circuit suitable to produce a circulation of fluid in output from the discharge port.

Abstract: A system for discharging dried product, particularly for drying filters, drying units and the like, comprising, on a container for treating and containing a dried product, a discharge hole that is controlled by a discharge valve, interposed on a pneumatic circuit suitable to produce a circulation of fluid in output from the discharge hole. An agitator is also provided which acts on the dried product to facilitate its outward conveyance.

Abstract: For portable use of peritoneal dialysis, a flexible bag of plastic material has two chambers therein, one being a dialysis liquid chamber (42) and substantially larger than a further disinfectant chamber (8); the bag is formed of thermoplastic material, heat-sealed together at seam lines extending thereacross, and sealed into the seam lines are a communication line (16) from the dialysis chamber (42) to the outside, and a branch duct (17) extending from the disinfectant chamber to the communication duct; the respective ducts are closed off at the inside of the chambers, after filling, by releasable closures, such as a ball squeezed into the duct, or a frangible pin which can be broken off by flexing the bag, thus permitting removal of, respectively, dialysis fluid and disinfectant from the respective chambers; used dialysis fluid can be returned into the bag.
