Patent DE-3317776-A1 (DE)
Inventor: REITH JOHANN-STEPHAN
IPC: B63J2/12
Filed: 1983-05-16
Abstract: Bulk cargo which is sensitive to condensate is confined in the cargo area of a seagoing or other vessel in such a way that it comes into direct contact with the walls surrounding the cargo area and is also in contact with moisture-laden air filling the remainder of such area. In order to prevent condensation of moisture on the walls surrounding the cargo area, the temperature of the walls as well as the temperature of air in the cargo area is maintained at a value such that the moisture cannot condense on the walls. This can be achieved by heating the confined air and/or the walls and/or by reducing the moisture content of confined air and/or by a combination of such undertakings.

Title: Device for the displaceable fastening of a mast foot to a sailboard
Inventor: WETZIG VOLKER
IPC: B63B35/79
Filed: 1983-09-30
Abstract: A device for the displaceable fastening of a mast foot to a sailboard, with a mast rail connected to the sailboard and a self-locking mast-foot slide displaceable on this rail, characterised in that the foot point of the mast is not attached above the centre line of the mast rail but laterally next to it so that, in combination with suitable shaping of the slide and mast-rail edges, desired initial tilting and self-locking of the slide occurs like a screw-clamp arrangement by a force exerted on the slide by the mast foot. The action of this arrangement of a mast-foot slide and mast foot is further improved according to the invention by devices for producing defined non-locking friction in the rail, as a result of which the initial tilting reliably occurs and self-adjustment is avoided. The aim of the invention is particular simplicity and reliability, even in the face of trouble caused by sand.

Patent DE-3441932-A1 (DE)
Title: Process for producing a liquid absorbate
Inventor: HUG SIEGISMUT DR
IPC: C01B17/74
Filed: 1984-11-16
Abstract: The process relates to the production of a liquid absorbate from a liquid F and a readily soluble gaseous substance A. In this process, beginning with the liquid F and a gaseous mixture of A and a gaseous substance B sparingly soluble in F, this mixture, in a first reaction vessel, is brought into intimate contact with the liquid F, the undissolved portions of gaseous substance B are conducted away and the resulting liquid phase of F and A and small portions of B is expanded in a second reaction vessel. The thus released portions of B (and possibly A) are withdrawn as a gas phase. A liquid absorbate is obtained composed of F and A, which is essentially free of B. The gaseous mixture used is at a pressure of above 1 bar and the resulting liquid phase composed of F, A and small portions of B is expanded in an evacuated vessel. The vacuum is generated by a gas jet pump which is driven by the pressurised gaseous mixture of A and B. The gaseous mixture exiting the pump is brought into intimate contact with the liquid F. Alternatively, the vacuum is generated by a liquid jet pump which is driven by the pressurised liquid F. In this case, the liquid which exits the pump is brought into intimate contact with the gaseous mixture of B and, possibly, A. <IMAGE>
Patent DE-3442628-A1 (DE)
Title: Low-pollutant integral internal-combustion engine with dual fuel feed
Inventor: SIMON MICHAEL DIPL ING
IPC: F02B1/04
Filed: 1984-11-22
Abstract: During the starting acceleration and full load phases diesel engines have a greater emission of pollutants. Compared to the diesel engine, spark ignition engines have very restricted compression ratios, air-fuel ratios and efficiencies in the case of otherwise knocking combustion. According to the invention both types of engine and their variants are improved by a divided fuel feed. In the process, prevaporising fuel fractions mixing with the air are fed in during the intake and/or compression phase, which are then ignited towards the tdc by injection of secondary fuel fractions. As a result soot and other pollutant fractions in diesel engines are reduced, whilst spark ignition engines or engines primarily running on petrol can be operated in the high excess air range and assume the advantages of diesel engines. This results, for example, in a type of diesel/petrol compound engine.

Patent DE-3503749-A1 (DE)
Title: Overload clutch
Inventor: WEISS HERMANN DIPL ING
IPC: F16D7/04
Filed: 1985-02-05
Abstract: The invention relates to an overload clutch for the transmission of torques. The two clutches are connected to one another via a connection (8) which can be released in the event of overload, such as wedge-shaped front-face toothing. In the event of overload, the connection (8) can be released counter to the force of a spring (9). The torque is transmitted by the connection via the spring (9), which at one end is connected firmly in terms of rotation to one clutch half (2) and, at its other end, bears the releasable part (11) of the connection. The spring is designed in such a way that it has a spring characteristic which initially rises with the angle of rotation and then falls. This ensures that the two clutch halves have stable positions both in the disengaged and in the engaged state. <IMAGE>

Patent DE-3527732-A1 (DE)
IPC: F24F8/158
Filed: 1985-08-02
Abstract: A filter apparatus, particularly for filtering air containing fumes is provided on the inlet side to an exhaust fan (8), electrostatic filters (36) and a flat test filter (38) immediately following the latter. On the outlet side of the exhaust fan (8) a cartridge filter (3) with a plurality of parallel filter cartridges (26) in the flow path is provided. In the flow path directly upstream of the test filter 38, as well as between outlet (14) and the inlet of cartridge filter (3), the pressure is measured by in each case one pressure indicating device (53, 54). When the electrostatic filter (36) becomes saturated, the contamination relatively rapidly increases the flow resistance of test filter (38), which is indicated by a pressure change between the electrostatic filter (36) and the test filter (38). If electrostatic filter (36) is not cleaned, then contamination then increases the flow resistance of cartridge filter (13), which is indicated by a pressure change in the flow path directly upstream of the cartridge filter (3). If there is still no cleaning or replacement of electrostatic filter (36), then the flow resistance becomes higher than the suction force of exhaust fan (8), so that the fact that no further suction is taking place is made immediately apparent.

Title: Collapsible wheel chock for vehicles
Inventor: SCHLITTER GEORG
IPC: B60T3/00
Filed: 1985-08-05
Abstract: Various vehicles and trailers must carry a wheel chock in accordance with article 41 of the Road Transport Licencing Act. The innovation according to my invention makes it possible to fold up the wheel chock. This offers great advantages when carrying a wheel chock in vehicles. It is possible to store the chock away in poorly accessible stowage compartments, even in passenger vehicles. Known designs are welded together from individual components. Due to the size of the wheel chock a certain volume of space is required in order to accommodate it in the vehicle. So that the chock does not fly around whilst travelling, it is generally clamped in a holder. Depending on the type of vehicle, it is not always easy to mount the holder on the body. These are great disadvantages. On roads with inclines - gradients, it is also of advantage to the car driver if a wheel chock is available in the event of a breakdown or fault.
