Patent DE-3714759-A1 (DE)
Inventor: GILLBERG-LA FORCE GUNILLA E
IPC: C09K23/00
Filed: 1987-05-02
Abstract: A spin finish composition is disclosed which contains an associative thickener which does not significantly affect the initial viscosity of the spin finish composition but which causes a substantial increase in viscosity as water contained therein decreases from its initial level to about 70%, and which effects no substantial change in viscosity of the composition as the water contained therein decreases from 40 to 0%. By virtue of this behavior, a spin finish composition results which can be improved in terms of spreadability on the yarns, package build, spin line coherence, the number of broken filaments and the tackiness of the snow formed on the texturings disks. Additionally, variations in the environment in which spin finish is applied e.g., temperature and humidity, do not substantially affect its performance.

Title: Process for producing a windsurf board and windsurf board
Inventor: HUBER ERASMUS
IPC: B29C70/86
Filed: 1987-07-17
Abstract: The invention relates to a process for producing a windsurf board (1), in which a foam core (2) is prefabricated, the outer contour of which essentially corresponds to the desired size of the finished windsurf board (1). At the surrounding lateral edge (8) of the foam core (2), a hollow space is created. A nonwoven layer, a woven layer and a foamable adhesive composition are applied onto the foam core one after the other. The outer shell (11) is subsequently produced under pressure around the blank (16) and the windsurf board produced in this manner is allowed to cure after the adhesive composition (6) has foamed, some of the adhesive composition (6) of the nonwoven fabric (4) and of the woven fabric (5) being displaced into the hollow space (14) and forming a reinforcement (10). <IMAGE>

Title: Process for decreasing the calcium content of waste waters from gas scrubbers operated with lime or limestone for separating off sulphur oxides and other acidic pollutant gases
IPC: C02F1/52
Filed: 1987-07-24
Abstract: Salt-containing waste waters (effluents) from exhaust gas scrubbers operated with lime or limestone for acidic pollutant gases frequently contain calcium chloride as the principal constituent. If discharge is still not possible after treatment, these waters must be evaporated. The salt product obtained is hardly utilisable and difficult to dispose of. The use of soda for a reprecipitation to give utilisable sodium chloride is frequently proposed. However, this solution only displaces the site of the disposal problems, since calcium chloride arises in turn in the production of soda. It is proposed to reduce the calcium content of the waste waters by interventions in the exhaust gas scrubber itself. This is possible by recycling the magnesium, precipitated in a waste water treatment in the form of Mg(OH)2, which is contained in virtually all waters of this type. As a further solution, the addition of sodium hydroxide solution or sodium sulphate directly to the scrubber is provided. Recycling or addition are carried out substoichiometrically with a stoichiometric factor of 0.5-0.99, based on the calcium content of the waste water with a conventional procedure. Fig. 1 shows a block diagram of the process according to the invention with recycling of Mg(OH)2 from the waste water treatment. Lime or limestone suspension (6), untreated gas (7) and make-up water (8) are fed to the exhaust gas scrubber (1). The purified gas (10), calcium sulphite and gypsum (9) and a waste water stream (11) leave the scrubber. The waste water is [lacuna] to a ... Original abstract incomplete. <IMAGE>

Patent DE-3740082-A1 (DE)
Inventor: BAIER WOLFGANG
IPC: F16H3/54
Filed: 1987-11-26
Abstract: Between an input member 4 and an output member 8 a planetary gearing is arranged, the transmission path of which can be modified by change-over measures so that the output member 8 can adopt different rotation rates from the input member 4. In one embodiment a planet carrier 12 is firmly connected with the input member 4; a ring gear 16 is firmly connected with the output member 8. A sun wheel 10 is selectively connectable fast in rotation through a hydraulic blocking device 24 preferably in the form of a gear pump whose outlet is throttled or blocked with a stationary support member 22. A free-wheel coupling 26 is arranged between the planet carrier 12 and the ring gear 16. When the blocking device 24 is blocked the sun wheel is held fast, so that on driving of the planet carrier 12 the hollow wheel 16 and thus the output member 8 connected with it are driven with stepped-up ratio. After release of the blocking device 24 the planet wheel 14 is not constrained, so that the drive to the ring gear 16 is interrupted. As a result of the loading by the secondary units the ring gear 16 is retarded until its rotation rate corresponds to that of the planet carrier 12 and it is driven by the latter through the free-wheel coupling 26. This mode preferably corresponds to a rotation rate ratio of 1:1 between the output member 8 and the input member 4. There is preferably a centrifugal clutch (48) between the engine and the gearing to preclude drive at low engine speeds. In various other embodiments the freewheel coupling and the blocking device act on different combinations of the elements of the planetary gearing. There may also be multiple sets of freewheel coupling and blocking devices. <IMAGE>

Title: Corrosion-protected tendon, in particular stressing member for prestressed concrete without pretensioning
IPC: E01D19/16
Filed: 1988-01-20
Abstract: In the case of a stressing member for prestressed concrete without pretensioning in accordance with Patent ... (Patent Application P 3734954.6-25), at least one of the anchoring devices (4) is configured as a coupling point in which the anchor disc (8), in addition to bores for anchoring the incoming tensioning elements (2'), also exhibits bores for anchoring the outgoing tensioning elements (2''). Arranged at a distance from the anchor disc (8) is a sealing disc (13) which closes off the cavity formed by piping (10) and is provided with through-passages for the passage of the tensioning elements (2', 2''). The cavity between the sealing disc (13) and the anchoring device (4) is filled with a plastically deformable corrosion-protection composition (14), e.g. grease. The piping (10) adjoins, on the one hand, the abutment body (9) and, on the other hand, the sheath (10). By virtue of this configuration of the coupling point, it is also possible to achieve the longitudinal movability of the tensioning elements (2', 2''), despite injection of the tubular sheathing with hardening material, with the arrangement of the coupling point. Consequently, such a stressing member can be used even for structures which are to be produced in sections, for example timed-shifting bridges. <IMAGE>

Title: Apparatus for washing filter cakes in tumbler centrifuges
Inventor: HULTSCH GUENTHER
IPC: B04B3/00
Filed: 1988-05-24
Abstract: Stationary wash nozzles are excluded for washing filter cakes in tumbler centrifuges, because the cake surface oscillates with respect to the wash nozzles. As a result, most of the washing liquid is reflected uselessly into the collecting housing. The object is to create a washing apparatus which avoids the reflection of the liquid and advantageously utilizes the kinematics of tumbler centrifuges for cake washing. In order to keep the distance between wash nozzle and cake surface constant, the wash nozzle (25) is mounted on the tumbler head (15) and fed via a co-rotating annular cup, so that the filter cake rotates past the wash nozzle with differential frequency between screen bowl (17) and tumbler head (15) and is uniformly impinged with preaccelerated wash liquid. In a preferred embodiment, the wash liquid impacts the cake region which is momentarily stationary relative to the screen surface (18). The apparatus is suitable for the uniform, splash-free and effective washing of filter cakes in tumbler centrifuges. <IMAGE>

Filed: 1988-11-05
Abstract: The subject matter of the invention relates to a method and a circuit arrangement for automatic telephonic or written alerting of videotex subscribers to new videotex messages which they have received but not yet read. On request, if a videotex message is not read, the telephone terminal to which the videotex terminal concerned is assigned is dialled up according to the invention by a fully automatic calling device installed in the videotex control centre; if the subscriber answers, the information that a videotex message for the videotex terminal, in fact for the message recipient with the co-user number which is then announced digit by digit, has been received and has not yet been read is conveyed by means of an automatic announcement via corresponding speech modules. If the call cannot be made, it is repeated at specific intervals. This alerting service can be extended in that a written notification which can be forwarded to the address of the message recipient can be printed out automatically by a printer controlled by the videotex computer ready for despatch, e.g. if the automatic telephone call cannot be made within a specific time period.
