Patent DE-3406445-A1 (DE)
Inventor: HUSTEN PETER F
IPC: G01V1/52
Filed: 1984-02-22
Abstract: The acoustical measuring device consists of a measuring probe which is immersed by means of a cable in the bore hole filled with drilling medium and can be moved in the axial direction therein. The measuring probe contains a transmitter which emits pulses. The echo signals are detected by a receiver fitted in the measuring probe. To detect the geophysically particularly important casing waves, which are received as strong useful signals undisturbed by transient and decay processes, the effective distance between transmitter and receiver in the measuring probe is smaller than half the wavelength of the signal transmitted in the drilling medium. This involves a reflection arrangement of essentially axial oscillators which are broad-band but prefer the lower acoustical frequency range. The measuring time of the sonograms received (microseismograms) is up to about one second.

Title: Laminated construction elements
Inventor: BRUINS DIEKO
IPC: E04C2/288
Filed: 1984-07-18
Abstract: Laminated construction elements which are produced in horizontal moulds from concrete-like, pasty construction material comprise load-bearing layers and insulating layers disposed between these. The load-bearing layers, which are connected together by webs or by the structure, provide the construction element with the required strength, the insulating layers provide protection against moisture, cold, sound and heat loss. The parts to be integrated into the construction element are inserted into the mould at the correct position. The work is easy and time-saving since the moulds are set up on site at a suitable working height; the work can even be carried out by semiskilled workers. The transport of the hardened construction element to its position in the structure is aided by a hanger which is incorporated into the load-bearing layers.
