Title: Fin line for microwave technology
Inventor: BISCHOF WERNER DIPL ING DR RER
IPC: H01P3/02
Filed: 1986-09-01
Abstract: The invention relates to a fin line for microwave technology. An electrically insulating substrate 1 carries conductor structures 2, 2' on both sides. The substrate is located in a waveguide, the longitudinal edges of the substrate projecting into longitudinal grooves which are located on the inner walls 5, 6 of the waveguide. The invention is based on the object of specifying a fin line, in the case of which tight tolerance limits on the values of its electrical properties are reliably maintained in the long term. This object is achieved, inter alia, in that the waveguide is formed from two waveguide elements 3, 4 and the substrate 1 is clamped into the longitudinal grooves. In the region of the longitudinal grooves, there are metallic connections between the two conductor structures 2, 2' in the form of through-metallised holes 12 (Figure 1). <IMAGE>

Title: Flat gasket, in particular cylinder-head gasket for combustion engines
Inventor: GIESEN FRANZ-JOSEF
IPC: F16J15/12
Filed: 1986-12-18
Abstract: In the case of a flat gasket, such as in particular a cylinder-head gasket for combustion engines, the full-area or part-area coatings on one or both sides are produced from a fluorinated rubber composition with addition of 1 to 10 per cent by weight of an epoxy resin curing system (based on the rubber proportion) and are completely vulcanised on the sealing surfaces. A good adhesion of the coating to the sealing surfaces, both of soft material and of metal, was ascertained, so that no detachment of the coatings with subsequent destruction during operation of the engine occurred, and the gaskets maintained their good sealing behaviour and their good resistance, with a long lifetime, even in continual service in the operating heat of the engine.

Title: Polymer-modified bitumen, preparation thereof and use thereof
Inventor: HOEHR DIETER DR
IPC: C08L95/00
Filed: 1988-06-11
Abstract: The invention relates to a polymer-modified bitumen containing from 75 to 98% by weight of standard bitumen and from 2 to 25% by weight of a thermoplastic from the group of the  alpha -polymers and  alpha -copolymers. Before being mixed into the standard bitumen, the thermoplastic is subjected to a treatment with atmospheric oxygen at from 200 to 250@C. The polymer-modified bitumen has a long storage stability, since it does not tend to separate, not requiring renewed homogenisation before use, and is suitable for use as binder in asphalt mixtures which are used for example in road building for high-quality road surfaces, noise-reducing top layers or drain asphalt covers. The polymer-modified bitumen confers on these road surfaces in particular an enhanced distortion resistance at high temperatures. When used as a binder in road building, the polymer-modified bitumen can be processed using the traditional machines.

Title: Circuit arrangement having a differential capacitor arrangement exposed to mechanical detuning
Inventor: GEVATTER HANS-JUERGEN PROF DR
IPC: G01P15/13
Filed: 1988-09-15
Abstract: In a circuit arrangement for the measurement of acceleration, two high-frequency voltages having phases mutually shifted by 180@ are applied to a differential capacitor arrangement, and an electrical measuring signal proportional to the acceleration is generated by evaluation of the high-frequency voltages; this is fed via summing amplifiers to the capacitor arrangement for compensating for the mechanical detuning. The electrical measuring signal proportional to the acceleration is thus dependent on manufacturing tolerances in the production of the differential capacitor arrangement. In order to eliminate the zero-point error and the linearity error, a direct voltage (U0), reduced or increased by an amount ( DELTA U0), and a feedback measuring signal (Ux), likewise increased or reduced by an amount, are fed to the summing amplifiers (25, 26) in the circuit arrangement. The circuit arrangement is suitable for the measurement of acceleration. <IMAGE>
