Title: Hold of hopper dredger ship for handling cargo
Inventor: SACKLOWSKI SIEGBERT
IPC: B63B35/30
Filed: 1994-04-13
Granted: 1995-07-06
Abstract: The cargo (1) consists of a viscous slurry. From the time it is loaded into the hold until it is discharged from flaps (3) at the bottom it is set in movement at intervals to prevent the very thick content from settling. This is achieved by swirling it with bursts of blown-in compressed air. At each air blow-in point at a pressure of approx. 10 bars during a few seconds approx. 500 litres of air is blown out. The air blower is an air lance (5) as is used in silos. It has a series of nozzle apertures or slits (7). On the port side and on the starboard side of the hold (1) at least one air blower is arranged.

Granted: 1996-04-04
Abstract: The invention concerns a gas and steam turbine plant (1) in which the waste gas (A) from the gas turbine (2) is used to generate steam. In order to be able to select freely a gas turbine model irrespective of its performance and avoiding losses of waste gas both for a new plant and for re-equipping an existing plant, a first partial flow (t1) of the waste gas (A) from the gas turbine (2) is used as air for the combustion of a fossil fuel (B), and a second partial flow (t2) of the waste gas (A) from the gas turbine (2) is used for generating waste heat steam. In order to generate steam, a combination of a fossil-fired steam generator (14) and a waste heat steam generator (15) is connected downstream of the gas turbine (2) on the waste gas side, in each case via a partial flow pipe (18 and 28, respectively). The steam is generated by combustion of the fossil fuel (B) and the waste heat steam is generated in a common water-steam circuit (12) of the steam turbine (10).

Abstract: FIELD: tannery. SUBSTANCE: method provides for following procedure: rotating member is moved under lower surface of hide. Being engaged with it hide beginning from edge and up to middle part of its surface takes hanging state, from which due to engagement with rotating member hide takes form of feeding apparatus.

Further movement of member is exercised without rotation and with separating hide upward or at an angle of no more than 15 deg. out of the vertical. During hide separation from processing equipment or from moving surface, for example, of conveyer simultaneous movement of rotating member together with separating hide is directed upward or at an angle of no more than 15 deg. out of the vertical. During loading on processing equipment and in pile on moving surface, for example, of conveyer movement of rotating member with hanging on it hide is directed vertically from top to down or at an angle of no more than 15 deg. out of the vertical and in case of loading on immovable surface - it is exercised horizontally or at an angle of no more than 30 deg. out of the horizontal.
