Title: Ultrasonic testing of composite mineral building materials - using longitudinal wave with axial and radial component, and analysing mixture of component frequencies by rapid FFT
Inventor: KROMPHOLZ GUENTER
IPC: G01N33/24
Filed: 1992-10-08
Abstract: In the non-destructive testing of natural, and man-made composite stones, ultrasonic waves are generated by a transmitter attached to the stone and picked up by a receiver coupled to the opposite face of the stone. The generator sends out a combination P-wave (longitudinal wave) with an axial and a radial component. The signal mixture of both component frequencies is subsequently analysed by rapid Fourier Transformation (FFT). The ultrasound generator/transmitter may be a piezo- electric, or a magnetostrictive oscillator. Various coupling aids, e.g. water or modelling clay provide good contact of the transmitter with the test piece. USE/ADVANTAGE - Ultrasonic testing of block form granular composite materials, e.g stone or concrete. Improved accuracy and reproducibility.

Patent DE-4323701-A1 (DE)
Title: Shaft seal, particularly for use on a throttle valve part
Inventor: JELINEK DIETER DR
IPC: F02D9/10
Filed: 1993-07-15
Abstract: When this throttle valve part is used in an exhaust duct, leaks occur, with the result that the spring elements age or break prematurely and thereby lose clamping force, giving rise to the possibility of leaks or malfunctioning. In contrast, the new shaft seal has the features that the sealing segments, which have the property of elasticity, are formed by recesses in a spring sealing washer, the recesses being covered completely by sealing segments of another spring sealing washer, arranged at an angular offset.
