Patent DE-3723484-A1 (DE)
Inventor: RILLY GERARD DR
IPC: H02M3/335
Filed: 1987-07-16
Abstract: A switching power supply in which a regulating voltage generated on the secondary side of the circuit is transferred to a control circuit on the primary side of the circuit so as to stabilize the dc operating voltages produced on the secondary side. In order to avoid the dangers involved from the absence of such regulation, a further or emergency regulating voltage is generated on the primary side of the circuit and if the regulating voltage from the secondary side is absent, the system is automatically switched to the further regulating voltage generated on the primary side, which further regulating voltage regulates the operating voltages to at most the rated values and preferably to values that are reduced by up to 10%.

Title: Process for purifying, in particular, domestic waste water in a biological sewage treatment plant
Inventor: WEIDNER LUDWIG
IPC: C02F3/10
Filed: 1987-09-02
Abstract: The invention relates to a process for purifying, in particular, domestic waste water (effluent) in a biological sewage treatment plant having at least one activated sludge tank (10) and one secondary clarification tank (12), using a preferred additive which, even at peak loads, ensures that maximum values of carbon compounds and nitrogen compounds in the clarified waste water are complied with. It is provided that the waste water (14) is fed to the activated sludge tank (10) in the vicinity of the ground (22), the biologically purified waste water (28) is removed from the surface (64) of the activated sludge tank and the waste water (14) in the activated sludge tank (10) is conducted essentially free from vertical turbulence. It is particularly advantageous to treat the waste water (14) in the activated sludge tank (10) in the presence of silicate mineral dust, an alkali basalt having a mean grain size in the range of 15  mu m having a high fines content below 7  mu m being used. The dusty natural basalt has a sharp-edged angular shape and a bulk density in the range of 1.16 g/cm<3> and a compacted density in the range of 1.53 g/cm<3>. The BET surface area should be approximately 6 m<2>/g; the content of alkali metals and alkaline earth metals together should be at least 25% and of alkali metals alone at least 4%. The softening point should be above 800@C. A favourable sink behaviour in activated sludge tanks (10) is achieved when the density of the solid natural basalt is at least 2.9 g/cm<3>. <IMAGE>

Title: Overload-indicating link for load-suspension means
Inventor: FRITZ HELMUT ING
IPC: B66C1/12
Filed: 1987-11-19
Abstract: This overload-indicating link for load-suspension means, in particular for chain suspension tackle, lashing devices or the like, consists of a preferably oval deformation link (1) in which the distance between its longitudinal legs (1a, 1b) is reduced on account of plastic deformation if a certain load limit is exceeded. An indicator device is provided to indicate this reduction. In order to obtain a robust indicating link of simple construction, the deformation link of which is free from additional weld points, the indicator device is designed as an indicating clasp (4; 8, 9) enclosing the deformation link (1) from outside and in the normal load case bearing against the outside of its legs (1a, 1b) at a distance from the longitudinal centre of the link. The inside width (d) of the indicating clasp (4; 8, 9), measured in the link plane, is greater than the outer distance (a2), measured in the overload case, between the legs (1a, 1b) of the deformation link. <IMAGE>

Title: Bearing arrangement for the pivotable articulation of wheel guide links of a motor vehicle on the vehicle superstructure
Inventor: TEICHERT ULRICH DIPL ING
IPC: B60G11/22
Filed: 1987-12-08
Abstract: The invention relates to a bearing arrangement for vehicle-central articulation of an arrow-shaped or arch-shaped axle body which interconnects the two wheel carriers of a motor vehicle rear axle and which additionally is articulated via guide links aligned obliquely to the longitudinal direction of the vehicle, the flexibility of which guide links transversely to the longitudinal direction of the vehicle increases automatically with increasing vehicle loading. The load-dependent flexibility is achieved with the aid of a cylindrical rubber/metal element, the cylindrical metal outer sleeve of which is connected positively to the axle body and the elastomeric core of which is mounted rotatably on a bearing axle which can be fastened on the vehicle superstructure transversely to the longitudinal direction of the vehicle, at least one of the two end faces of the elastomeric core lying in a plane running obliquely to the bearing axle and in this case bearing against a likewise oblique bearing surface which is fixed in space. The oblique end faces and bearing surfaces are in this case dimensioned and arranged relative to one another in space in such a manner that the elastomeric core is only slightly prestressed at maximum vehicle loading and is braced increasingly axially on decreasing vehicle loading by the associated twisting of its end face relative to the bearing surface. <IMAGE>

Patent DE-3804216-A1 (DE)
Inventor: LAUER WALTER DIPL ING
IPC: H04M7/00
Filed: 1988-02-11
Abstract: The invention is designed to provide a universal circuit arrangement which is suitable for transmitting and receiving a multiplicity of seizure criteria, and also to enable the transmission of dialling information, where the trunk line transmission can be adapted according to the relevant application with no need for any modifications to be made to the universal circuit arrangement. Individually controllable switching means are connected in pairs to each of the line wires belonging to the trunk line, where in each case one can connect the line wire directly through to the relevant forwarding wire and in each case the other can set up a connection to the other wire. A control device determines, according to the relevant operating condition, which switching means are permanently or temporarily connected through or disconnected. The circuit arrangement is designed so that a multiplicity of possible circuits can be provided, where the control device simply needs to be set according to requirements. This ensures that the correct polarity is known in each case and that a polarity reversal carried out by the distant exchange can also be identified. <IMAGE>

Patent DE-3819331-A1 (DE)
Title: WC flushing cistern
Inventor: JEHLE WALDEMAR
IPC: E03D5/00
Filed: 1988-06-04
Abstract: The object of the Duovil WC flushing cistern is to flush WCs with different types of water. This object is achieved by the installation of two float valves. The float valve W1 is connected to the drinking water and another float valve is connected to the self-supplied water* (type is no importance). *Self-supplied water = rainwater, self-supplied spring water, groundwater, stream water, etc. The float valve W1 installed in the Duovil opens automatically after 2 minutes, only when the self-supplied water has failed, and fills the Duovil with drinking water. No loss in comfort or reduction in the standard of living and hygiene result by using self-supplied water* for flushing the WC. Optimum utilisation of the accumulated rainwater and self-supplied water* is achieved by the Duovil WC flushing cistern, since drinking water is used for flushing the WC only when the supply of the abovementioned water fails. It does not require any electrical and manual changeover. If necessary, the changeover takes place automatically in the WC flushing cistern*.
Patent DE-3821818-A1 (DE)
Title: Liquid-crystal cell

Patent DE-3827028-A1 (DE)
Inventor: WEISSINGER ULRICH
IPC: A47C23/06
Filed: 1988-08-10
Abstract: A resting surface for beds comprises flexibly mounted, interspaced parallel slats (17), the front faces of which are mounted in support elements (22) slidingly arranged on lateral parts (2, 3) of the bed. The lower surface of each support element (22) rests on several superimposed straps (7, 7a). This ensures progressive resilience when the support element (22) moves vertically. The resting surface thus provides excellent, well-sprung comfort and adapts readily to the profile of the body. Even the heaviest bodies do not move the corresponding support elements as far as the limit stop, which would result in a loss of resilience. Being progressive, resilience is guaranteed even when the total body weight is applied to the resting surface at a single point.
