Title: Self-locking differential for motor vehicles
Inventor: FRIEDRICH KARL ING
IPC: F16H48/10
Filed: 1987-04-16
Abstract: A self-locking differential for motor vehicles comprises a driven housing (1) and differential elements (2, 3, 5) pivotably mounted therein, each one of which (3, 5) is rotationally fixed to an output shaft (4, 6). In the housing (1), brake plates (8, 9) are provided for at least one (5) of the differential elements (3, 5), which plates can be pressed against one another by means of a displaceable pressure disc (10). In order to achieve self-locking independently of a support force originating from the vehicle wheels, one (5) of the differential elements (3, 5) together with the pressure disc (10) rotationally fixed in the housing (1) forms an expansion unit (5, 10). On the end face, one part (10) of this has ring profiling (11) comprising radial elevations and depressions with inclined faces. In the other part (5), at least one pair of axially parallel pistons (12, 12a) is supported, which are aligned with their rooflike ends (13) against the ring profiling (11) and are hydraulically acted upon at their other ends. The cylinder bores (14) of the two pistons (12, 12a) are connected by way of a passage (15), provided with a restrictor (16). <IMAGE>

Title: Process for producing a fibre-reinforced plastic component loaded by tensile stresses
Inventor: RAU THOMAS DIPL ING
IPC: B29C70/56
Filed: 1987-06-02
Abstract: For introducing inherent stresses (sD, sZ) into fibre-reinforced plastic layers (1, 2) of a torsionally loaded component, a gap or crack (3) is produced, by means of forces applied to the component, in at least one of the layers (2) and is filled with a material (4) while the force is acting; after removal of the forces, the gap (3) cannot close again, as a result of which the inherent stresses (sD, sZ) are produced (Figure 4). <IMAGE>
Patent DE-3721642-A1 (DE)
Title: Binders and plasticisers for carbon-containing ceramic compositions
Inventor: SCHRAVEN THOMAS DR ING
IPC: C21B7/12
Filed: 1987-07-01
Abstract: The invention relates to binders and plasticisers for refractory, carbon-containing, tar-free ceramic compositions which are made up of surface-active compounds, alicyclic hydrocarbon products and also carbons in very finely divided form. Cationic, anionic, nonionic and amphoteric surfactants, terpenoid hydrocarbons and natural and processing products and derivatives containing these and also carbon black or graphite as suppliers of carbon can be used. The customary tar content of ceramic compositions such as, for example, tapping hole compositions can thereby, while retaining the required technological properties, be completely replaced and the liberation of ring compounds (cyclic compounds) which are hazardous to the environment and to health and which arise from the tar content can thus be avoided.

Abstract: The invention relates to a process for the preparation of hydrophilic, film-form polyacetylene by modification of film-form polyacetylene whose proportion of sp<3>-hybridised carbon atoms in the polyacetylene is less than 0.5 mol % based on the total carbon content of the polyacetylene, characterised in that the film-form polyacetylene is first reacted with chlorosulphonyl isocyanate, and the resultant product is then hydrolysed by means of aqueous base.
Patent DE-3723729-A1 (DE)
Title: Shaft seal, particularly for shafts of gas-cooled generators
Inventor: LONGREE ALEXANDER
IPC: F16J15/44
Filed: 1987-07-17
Abstract: The present invention relates to a shaft seal, particularly one for shafts of gas-cooled generators, with a sealing ring (22) which surrounds the shaft (35), floats on an oil film, does not rotate with the shaft and, on its inside, has at least one oil outlet groove (28.8). The holding device for the sealing ring (22) consists of a guide plate (21) and of a relief flange (23) which is fastened to the guide plate (21) by means of stay bolts (24, 25) and spacer sleeves (26, 27). This construction of the holding device makes the sealing ring (22) accessible from outside, thereby facilitating the centring and readjustment of the sealing ring (22) in relation to the shaft (35). A holding device of this kind can be constructed both for single-flow seals and for double-flow seals. The construction of the seal and of the oil supply is simplified and oil consumption is minimised by the better possibilities for the adjustment of the sealing ring (22). <IMAGE>
Patent DE-3728280-A1 (DE)
Title: Conveying-flow deflector
Inventor: GERHARD GUENTER
IPC: B65G53/56
Filed: 1987-08-25
Abstract: The deflection of a conveying flow in pipelines, in particular of granular solid materials by pneumatic conveying methods, takes place by manual reconnection, by blocking the line systems by means of individual units or by conveying-line switches having internal adjustable line parts. In these methods, during changing-over, the conveying must be shut down and the route section must be freed from conveyed material. The novel conveying-flow deflector is to be able to change over during the conveying operation by means of a drive and even in the case of the highest possible conveying pressures, while having the smallest possible installation dimensions. By way of a pivot point (4) in the vertex of a deflection housing (1), a tangentially arranged change-over valve (2) is swivelled, by means of any desired drive, in front of an internal conveying-pipe exit piece (3) and thus closes the preselected pipeline system with simultaneous opening of the other. The conveying-flow deflector is suitable, in particular, for use with all known pneumatic conveying methods; however, in particular because of its compact method of construction and its adaptability, in terms of material, to all conveyed materials, it can also be used in the pipeline systems in hydroeconomy and in the chemical, gas and power station industries.

Patent DE-3732324-A1 (DE)
Title: Method of manufacturing new types of measuring probes for ion-selective/material-selective glass electrodes
Inventor: AFFONSO ALVARO PROF DR
IPC: G01N27/36
Filed: 1987-09-25
Abstract: A new type of measuring probe suitable for manufacturing ion-selective/material-selective electrodes is described as supplementary application to Application P 3729681.7. Advantages are that a smaller amount (0.1 ml) of sample solution is required. Furthermore, only the glass surface contacts the sample solution and no contamination by the reference electrolyte is possible. The measuring probe comprises an ordinary pH glass electrode whose active surface is divided into two halves. One part forms a pH measuring probe with a reference electrode and associated diaphragm. This part is enclosed in a chamber and is in continuous contact with a buffered graphite suspension. This produces a constant potential. The other part of the glass electrode projects from the chamber and is immersed in the solution to be measured. This produces an additional potential which is proportional to the hydrogen ion concentrations. The resulting potential is finally measured.

Patent DE-3740226-A1 (DE)
Title: Method for pressing out (expelling) the fat phase of comminuted and heated cocoa beans (nibs) or sheanuts
IPC: A23G1/08
Filed: 1987-11-24
Abstract: The method for defatting comminuted cocoa beans (nibs) or sheanuts is carried out in a screw press having only one horizontally arranged screw shaft. Before the entry of these products into the screw press, they are sprayed with cold water. This leads to an increase in friction and thus to conversion of the products into pressable processing masses. The course of processing is influenced positively in comparison with experience previously made with the two products. The pressing of the two materials can also be carried out in two screw presses arranged one after the other.

Title: Apparatus for measuring the flatness of rolled strip in hot wide-strip mills
Inventor: SEIDEL JUERGEN
IPC: B21B38/02
Filed: 1988-09-20
Abstract: Unevenness or waviness in the rolled strip, for example edge waves and central waves lead inevitably to errors in profile measurement because the profile-measuring instruments erroneously detect an excessively large strip thickness in the region of waves. The present invention relates to an apparatus for measuring the flatness of a rolled strip (10) subject to tension, a segmented tension-measuring roller (2) consisting of a plurality of individual rollers being arranged on the exit side of the last stand (1) of the finishing train, and there being a pinch rolled unit (driver) (3) for the application of the necessary tensile forces close behind the tension-measuring roller (2) in the rolling direction (W), and the profile-measuring device (20) being mounted between the last stand (1) and the pinch roll unit (3). It is particularly expedient for the profile-measuring device (20) to be arranged directly behind the tension-measuring roller (2). <IMAGE>

Patent DE-3840193-A1 (DE)
Title: Tubular filter
Inventor: ARZT BERNHARD DR ING
IPC: B01D29/11
Filed: 1988-11-29
Abstract: In tubular filters for solid/liquid separation, deposits can occur on the internal surface of the filter tubes (5), as a result of which the filtrate flow can greatly decrease. This makes oversizing and cleaning of the tubes necessary. This cleaning is conventionally carried out at intervals and leads to interruptions in operation and thus to increased production costs. The object underlying the invention is to design a tubular filter in such a way that continuous cleaning and thus continuous operation are possible in order to decrease the capital and production costs. This object is achieved by arranging in the lower chamber (4) of the vertical tubular filter a perforated plate (10) which separates off a space (4b). In this space and in the filter tubes (5) there is a granular mass (11) which is fluidized by the medium to be purified and which keeps the internal surface of the filter tubes (5) free of deposits by the turbulence generated and by mechanical contact. The tubular filter according to the invention is suitable for use in all processes and methods which depend on solid/liquid separation and purification of liquids with the lowest possible costs. <IMAGE>

Title: Superconductive linear composite objects and a method for their production
Inventor: INOUE KIYOSHI
IPC: H01L39/14
Filed: 1989-02-24
Abstract: The invention makes available a long, linear composite object or body which is characterised in that a large number of composite filaments are provided at a distance from one another in a continuous layer, this layer being composed of or consisting of copper, a copper alloy, niobium, tantalum or vanadium. Each of the composite filaments has a structure such that at least one strand of a linear body is surrounded by an aluminium alloy or niobium, especially being sheathed or enclosed by them. The linear body is essentially composed of an extremely fine superconductive Nb3Al compound in the form of a thread, these threads or filaments having a mean diameter of approximately 0.03  mu m to approximately 1  mu m. The said composite object or body can be produced by drawing a composite material, which is composed of (a) an aluminium alloy and (b) niobium, together with copper or a copper alloy and repeating this operation one or more times until the mean diameter of the aluminium alloy (a) is approximately 1  mu m or less, and heat treatment of the resultant linear composite material. These composite objects or bodies have excellent superconductive characteristics and characteristic data in strong magnetic fields and AC magnetic fields.
