Abstract: A new process is disclosed for sealing and renovating the inside of systems of laid ducts with a small inner diameter. Leaks are stopped by a sealing material introduced into the duct and the inside of the duct is renovated by abrasive blasting and re-lining. According to the process, a sealing material containing finely ground bentonite swellable in water and/or a hydraulically soluble plastic dispersion dry composition, as well as inert additives, is blown through the duct, and the duct is charged and maintained with a water vapour/air mixture under 2 bars overpressure or more, or the duct is filled with or crossed by water or the inert stopping agent is introduced into the duct by a water current. The installation for carrying out the process has, among others, either a compressed air distributor (3.02) with an air supply line (3.04) and air outlet lines (3.05 to 3.07); said lines bearing among others valves and manometers (3.15 to 3.27) or the corresponding water installation.

Abstract: An adjustable feeder pan system for feeding poultry and a related method is provided. The feeder pan system (10) includes a cone portion (100), an excluder portion (400) that includes a number of anti-rake and radially disposed fins (402), a skirt (300), a feed pan (200), a cap (600), and optionally a feed shut-off component (500). The cone (100) includes a pair of stops (118) that may selectively engage with one of a number of pairs of corresponding slots (416) of varying depths on the excluder portion (400) so as to provide multiple feed levels as desired and depending upon the size and age of the poultry being fed.
