Title: Method for detecting faults in industrial process plants
Inventor: HITZIG KARL
IPC: G05B23/02
Filed: 1986-06-12
Abstract: It is no problem to detect faults in industrial process plants when monitoring constant operating variables within a predetermined interval. A reliable monitoring of operating variables which change due to the operation presupposes that the limit values also exhibit a corresponding variation with time at a predetermined distance from the operating variables. Using the method according to the invention, a synchronism of reference input, limit value and the nominal state of the operating variable to be monitored, which allows a more sensitive detection of faults than previously and thus ensures optimal protection of the plant is achieved even in the case of disturbed and faulty measurement values.

Title: Process for treating weathered ores containing pyrochlore from a carbonate-type deposit
Inventor: ROETHE GUSTAV DR
IPC: B03D1/02
Filed: 1986-08-08
Abstract: Process for treating weathered ores containing pyrochlore from a carbonate-type deposit. In this process, the recovered ore is first comminuted and ground to a fineness suitable for digestion. The ground ore is then, if appropriate after classification and also cleaning by attrition and washing, elutriated, the natural fines fraction being separated off. The ground and elutriated ore is sorted by preflotation, and the pyrochlore fraction of the preconcentrate is concentrated by a downstream multi-stage purification flotation. Amines as flotation reagents and emulsifiers as collecting agents, silicofluorides and acids as activators for pyrochlore and substances for passivating iron oxides, preferably starch, are added. According to the invention, citric acid is added for conditioning the flotation pulps. <IMAGE>

Title: Sailing vessel hull with steering fins and ballast trimming vanes
Inventor: FRITSCH JUN PETER
IPC: B63B41/00
Filed: 1986-08-18
Abstract: The problem with a sailing yacht is known. High superstructure, mast, sail, the wind pressure and thus the drift. In order to prevent the drift and capsizing of the boat, a heavily ballasted keel is attached to the hull according to the age-old and fully superseded custom. This obsolete type of construction makes the boat sluggish and inflexible. Four extendable and retractable steering fins replace keel and rudder much more effectively. They guide the hull as if on rails and make it manoeuvrable like a formula-one racing car. Additional ballast trimming vanes at the steering fins enable the entire ballast weight to be trimmed over the entire width of the vessel, and at the same time forward and aft. It is thus possible to sail the sailing yacht far closer to the wind. The electronically, hydraulically controlled ballast trimming vanes stabilise the boat in the longitudinal axis, keep contact with the water and put the boat into an optimum planing phase.

Patent DE-3644182-A1 (DE)
Title: Shut-off device
IPC: E03C1/04
Filed: 1986-12-23
Abstract: Shut-off devices for installation underneath work surfaces are generally secured by way of an element which is screwed on to that end of a housing extension which passes through the worktop. The knob is placed on the valve-operating spindle projecting from the housing extension and is screwed to it. As the valve of the shut-off device is opened and closed, the spindle performs a linear motion which is transmitted to the knob and, as a result, the knob too moves up and down. With this arrangement, there is the risk that dirt will penetrate underneath the knob and this can lead to malfunctioning of the shut-off valve. To prevent penetration of dirt, a nut (3) is provided to fix that end (12) of the housing extension (8) which projects above the surface (30) of the worktop (2), and the knob (4) has an axial guide (14) for the accommodation of the head of the spindle (5) and can be placed on the nut (3) and fixed on the latter in the axial direction. By virtue of the fact that the knob (4) is fixed on the nut (3), it performs only the rotary motion but not the linear motion of the spindle (5) and, as a result, it is impossible for dirt to penetrate underneath the knob (4). The knob (4) fixed on the nut (3) is suitable especially for shut-off devices which are to be installed under a work surface, such as corner valves, shut-off valves, mixer batteries etc. Above the worktop there is only...

Title: Continuous conveyor
Inventor: GERLACH KAY
IPC: B65G17/42
Filed: 1987-05-06
Abstract: Continuous conveyor having carrying elements (buckets 11) fastened to drawing elements, namely belts (10), are accompanied by difficulties in the fastening of the carrier elements (buckets 11) to the belts (10). When loaded, the carrying elements tend, in time, to damage the belts (10). Such damage, for example tearing-out of the plate screws (18) used for fastening, is to be avoided by means of the invention. For the purpose of avoiding damage to the belt (10), the invention therefore proposes to arrange a tearing-out preventer (edge strip 22), which supports the belts (10), in the region of the belt connection. The tearing-out preventer according to the invention is particularly suitable for bucket conveyors, scraper conveyors or the like, in which the carrying elements (buckets 11) are fastened to belts (10). <IMAGE>

Inventor: IBURG JOHANNES
IPC: B22C15/28
Filed: 1987-05-25
Abstract: The compacting and hardening of the sand layers close to the pattern (3) is effected by the expansion of compressed air present in the sand filling (4). The sand (4) is initially loosely filled into the mould (1) which, after sealing, is filled with air admitted under pressure to the space (7) above the sand so that a pressure equilibrium is formed within the filling (4). This pressure is then abruptly vented to the external atmosphere from vents (12, 11) in and adjacent the sides of the pattern surface (3) and supporting plate (2), so that the equilibrium of forces acting on the individual sand grains is cancelled on one side. Prior to completing the venting of the sand filling (4), the space (7) above the sand is vented, and preferably immediately after this commences, the sand is mechanically compacted in its surface area by means (9). Venting of the sand may optimally be effected cyclically, and the sand may be vibrated during venting by means (24). <IMAGE>

Title: Passive sorption cooling system
Inventor: GROMOLL BERND DR
IPC: H05K7/20
Filed: 1987-11-27
Abstract: For the purpose of cooling shelters for electronic equipment, passive cooling systems are advantageous, whose operation does not require mechanical components driven by imported energy. The known passive cooling systems operate according to the thermosyphon (thermosiphon) principle, using a water reservoir, and require uneconomical reservoir sizes. According to the invention, a passive sorption cooling system is provided in which the lost heat produced in a room 2, in the event of high ambient temperatures, is stored temporarily (buffered) in a heat reservoir (heat accumulator) 6. Storage is effected by sorption, by means of a sorbent 22, of a refrigerant 20 evaporating in an evaporator 4. In the event of low ambient temperatures, the lost heat is used to drive out the refrigerant 20. The refrigerant 20 driven out is liquefied in a condenser 8 arranged outside the room 2 and, under the influence of gravity, flows back to the evaporator 4.

Title: Active local area network with wavelength diversity
Inventor: KRISCH LOTHAR PROF DR ING
IPC: H04B10/278
Filed: 1988-03-04
Abstract: In the active local area network according to the invention with a ring or bus topology, the wavelength  lambda  of the signal on the light wave line (0) is changed from data station (1) to data station (1). The signal of one data station differs accordingly from the non-regenerated signal which is fed via the attenuating bypass (2) in terms of its wavelength  lambda . The stronger signal transmitted by the preceding station is in each case processed in a data station (1) during fault-free operation. If one data station (1) fails, a signal which can be processed is nevertheless still forwarded via the bypass (2) to the next data station (1). In this way, the active local area network remains operational even if one or more data stations fail. <IMAGE>
