Title: Process for producing a three-dimensionally structured film web
Inventor: BRONNER JUERGEN DR
IPC: B29C51/10
Filed: 1983-04-08
Abstract: In a process for producing a three-dimensionally structured film web from a thermoplastic polymer, the polymer is extruded through a sheet die to form an initially smooth film web, and this smooth film web, while it still has a temperature in the vicinity of the melting temperature of the polymer, is deposited on a moved receiving element disposed substantially vertically below the sheet die, which receiving element has a three-dimensionally structured surface, where the polymer contacts the three-dimensionally structured surface of the receiving element in a manner such that it is deformed. In this manner three-dimensionally structured elements with increased compressive strength can be produced in a more simple manner than in the state of the art. They can be used as spacers or, laminated to a spin-bonded fabric, as vertical drainage elements, for example on building walls in contact with soil.

Patent DE-3316761-A1 (DE)
Title: Predictive control method
Inventor: KENNEL RALPH DIPL ING
IPC: H02M7/162
Filed: 1983-05-07
Abstract: The proposed ''predictive control method'' optimises the control behaviour of controllers whose control paths contain dead times. Typical representatives of these are converters which, from the control-engineering viewpoint, even have variable dead times, that is to say are time-variant transmission elements. The basic principle of the predictive control method is the prior calculation of the behaviour of the control path for the time period following the dead time. The drive signal (control voltage) for the control path is derived from the result of this prediction. Fig. 5 demonstrates the predictive method on a current controller for a line-controlled converter. By making reference to the next subsequent converter switching state, the controller calculates the required load current behaviour. As a result of the comparison of this ''precalculated'' signal with the actual current signal, the change-over time for the converter can be determined. <IMAGE>

Title: Method for producing a Y-branch
Inventor: FORBRIG BERND DR ING
IPC: G02B6/28
Filed: 1983-07-01
Abstract: The aim of the invention is low-loss production of Y-branches composed of optical fibres usual in fibre-optic communications engineering, which is reproducible and economic. The object is to specify a method for producing Y-branches, in which a low number of operations are required and a high transmission coefficient is achieved despite a reduced mechanical precision. This is achieved when the end faces of two optical fibres, which are embedded in a force-closed and form-locking fashion in separate housing members, are ground in such a way that when the housing members are joined the optical fibres taper toward one another. After bonding of the ground surfaces, the housing members are ground in order to achieve a common assembled cross-sectional surface of the two optical fibres, which is bonded to a planar end face of a third optical fibre so as to produce a Y. <IMAGE>

Title: Reinforcing mat
Inventor: BRAUN KARL
IPC: E04C5/04
Filed: 1983-07-29
Abstract: In a reinforcing mat of longitudinal and transverse bars which cross one another and are welded together at the crossing points, there are provided at the mat edges, within the required anchoring length (lvo) of the bars (1'') to be anchored, at least one bar (4) running transversely thereto and, at their outermost end, in each case a rigid end-anchoring element. Rigid anchoring elements, such as for example upset heads, act in a slip-free manner against non-rigid anchoring elements, such as welded-on transverse bars, so that they are arranged at the outermost end of a bar and can absorb forces there. The combination of non-rigid and rigid anchoring elements leads to optimisation of the anchoring and abutting length and to improvement in the application of reinforcing mats from a technical and economical point of view. <IMAGE>

Title: Collision warning device for motor vehicles, based on ultrasound
Inventor: GROLL HORST PROF DR ING
IPC: G01S15/931
Filed: 1983-11-12
Abstract: A collision warning device for motor vehicles is proposed, which is based on ultrasound and in which the transmission oscillator and the reception oscillator are arranged at a relatively large horizontal distance from one another on the rear side of a motor vehicle, in order to prevent collisions, primarily during parking. The range to an obstruction causing a risk of collision is determined from the propagation time of the ultrasound, points of identical propagation time being located on an ellipse which has the two oscillators as focus points. By using an additional oscillator, the direction of the obstruction can also be determined. Warning information for the driver of the motor vehicle can be derived from the range determination.

Title: Single disc gas turbine
Inventor: MAYER KARL
IPC: F02C3/045
Filed: 1984-02-29
Abstract: To sum up it may be said that the single disc gas turbine according to the subject of the invention, represents a genuine innovation in the sphere of heat engines owing to the double function of the rotor disc with blades or ducts and the associated advantages compared to gas turbines of conventional type, especially since it is possible to construct such single disc gas turbines for far greater power outputs. Using the principle according to the invention, that is with a not all too great efficiency, engines with a large to very large power output can also be built by assembling a plurality of small turbines - this applies in particular to their use in motor vehicles -, the individual small turbines being switched on and off according to the power requirement so that at all times only the required power is generated. With this method a total efficiency can be achieved which is no less favourable than that of good piston engines. The single disc gas turbine according to the subject of the invention combines the advantages of gas turbines of conventional type with the thermodynamic advantages of piston engines without, however, exhibiting the disadvantages of both types of engine. In addition the fact that the single disc gas turbine according to the subject of the invention can be operated with all standard commercial liquid or gaseous fuels is a further advantage. At the same time the fuels do not require additives of any kind, such as, for example, lead compounds or ... Original abstract incomplete.

Title: Ball socket for a ball joint
Inventor: SIHN WILFRIED
IPC: F16C11/06
Filed: 1984-07-10
Abstract: A ball socket for a ball joint with a shank and a cavity for receiving a spherical head is of three-part design: it consists of a housing part, a receiving part, axially displaceable therein, for the spherical head and of a spring part supported on the housing part and acting on the receiving part. The inside diameters of the housing part and the outside diameters of the receiving part are matched to one another in such a way that, in a certain position of the receiving part in the housing part, an axial expansion of the latter for the introduction of the spherical head is possible while, in another position (locking position), this is not possible. The spring action ensures that the receiving part remains in the locking position. This ball socket makes possible automatic engagement and automatic locking of the spherical head after introduction into the ball socket without additional tools or additional operations.
