Title: Cutting wrapping of bales by air or water jets - uses different intensities and sectional shapes of jet according to types of bale.
Inventor: HERGETH HUBERT
IPC: B26F3/00
Filed: 1992-02-18
Abstract: The jet intensity can be increased automatically around the wrapping region by sensors which carry out measurements.

Title: Floating sludge removal - using fixed take=off trough and moving shield to displace floating matter into trough and retracting and lowering for further matter to float in
Inventor: KETTENBACH KARL ING GRAD
IPC: B01D21/04
Filed: 1992-09-18
Abstract: To remove floating sludge from a basin, a fixed take-off trough is used with a clearance shield moved to push the sludge into the trough. After each shield movement, it is retracted from the trough to be held and lowered, which allows floating sludge to disperse into the cleared area and to be displaced into the trough on the next shield movement. The take-off trough (5) is pref. at a static bridge (4). The clearing bridge (8) is supported by a central bearing on the fixed bridge (4). The drive (14) for the clearing bridge (8) can be reversed. USE - The method is for the removal of floating sludge at settling, thickening or biological processing basins.
Patent DE-4244137-A1 (DE)
Title: Vehicle air conditioning system with unidirectional fluid flow in heating and cooling modes - has valve to direct flow to outer heat-exchanger for cooling and to inner heat exchangers for heating
Inventor: MATSUOKA TAKAYOSHI
IPC: F25B41/04
Filed: 1992-12-24
Abstract: The output from the compressor (31) is switched by the control valve (32) either to the outside heat exchanger (38) or direct to the first of the internal heat exchangers (33). The outlet of the outer heat exchanger has a non-return valve (70) to connect to the first inner heat-exchanger. A pressure reduction valve (34) is set between the two inner heat-exchangers with the second heat-exchanger (35) feeding the pump inlet. Switching the control valve selects cooling or heating without changing the fluid flow direction. A blower (37) upstream of the inner heat-exchangers controls the airflow. Heat sensors spaced about the system, and a selector control, are connected to a control unit (43) for a simple control. For enhanced heating effect part of the airflow can be recycled (50) to the front of the blower. ADVANTAGE - No risk of icing the heat exchangers, no defrost facility required, simple valve control.

Patent DE-4312803-A1 (DE)
Title: Device for profiling sails
Inventor: NEUHAUS DIETMAR DR
IPC: B63H9/06
Filed: 1993-04-20
Abstract: Sail battens for profiling sails for wind-driven vessels are known. They are made of an elastic material so that the battens have a suitable bending curve under predetermined loading. The known sail battens have the disadvantage that a change in wind pressure changes the bending curve and thus the aerodynamic profile of the sail - an undesirable change for the most part. The object of the invention is to create a dimensionally stable sail batten. This is achieved by the sail batten consisting of batten pieces which are connected to one another by articulated joints. The articulated joints can only be moved in a predetermined angular range and thus form with the batten pieces a sail batten which is also dimensionally stable during changes in the wind pressure.
Patent DE-4313725-A1 (DE)
Title: Oil-collecting tank which skims off oil from a slightly agitated water surface without an artificial energy supply
Inventor: GRANZOW JOACHIM DR
IPC: E02B15/10
Filed: 1993-04-27
Abstract: In the rest state, the tank is filled with water and is almost completely submerged. Its density must therefore be slightly below 1, the distribution of which provides for an upright position. At least one inlet valve is located on the top side and an outlet valve on the underside. The tank will periodically submerge and surface even in slightly agitated water. In the surfaced state, water flows off through the outlet valve due to the force of gravity and air forces its way in through the inlet valve. In the submerged state, a mixture of water and oil flows through the inlet valve into the tank. The outlet valve blocks the ingress of water from below. The efficiency is improved by a high tank mass. Since the tank density overall has to remain below 1, this can be brought about by a combination of ballast and buoyancy. The body can be used wherever a water/oil mixture is located which cannot be disposed of or is not to be disposed of as a whole but where merely the oil film is to be skimmed off. <IMAGE>
