Patent DE-3704283-A1 (DE)
Title: Plug coupling
Inventor: BUMILLER REINHOLD
IPC: H01R24/38
Filed: 1987-02-12
Abstract: In the case of known plug couplings, the contacts of the plug are rings which are arranged axially one behind the other, spaced apart. During insertion of the plug into the plug socket, the front contact ring moves over all the mating contacts of the plug socket, as a result of which defects can occur. In addition, the plug is relatively long because of the contacts being arranged axially one behind the other. In the case of the new plug coupling, only the mutually associated contacts and mating contacts are therefore intended to come into contact with one another during the plug insertion process. At least over a part of their length, the contacts run in the plug insertion direction of the plug. In consequence, the contacts do not move over various mating contacts in the plug socket while plugged together, but are in contact with the mating contacts associated with them, from the start. The plug coupling can be used in underground workings, in quarries, on building sites and the like. <IMAGE>

Title: Piezopolymer ultrasonic transducer
Inventor: PLATTE MICHAEL DIPL PHYS DR
IPC: B06B1/06
Filed: 1987-03-28
Abstract: The invention relates to a piezopolymer ultrasonic transducer for generating and detecting ultrasound in (coupling) liquid, comprising at least one layer 3, situated between a front and a rear electrode 2, 2', of a piezoelectric high polymer, a rear end body 1 and a protective layer 4 on the transducer side situated adjacently to the transmitting medium. The object of the invention is to provide an ultrasonic transducer which is intended for the working or nominal frequency arranged between 1 and 10 MHz, and which can be fabricated by a simple procedure from thin high-polymer piezoelectric layers whose thickness produces a resonance frequency which is at least twice the working or nominal frequency of the ultrasonic transducer and whose impedance is consequently reduced so that an electrical impedance matching to the low-impedance output of commercial ultrasonic units is possible. According to the invention, the object can be achieved in that the protective layer 4 is designed by dimensioning, in accordance with the invention, the relationships between the acoustic impendance of the protective-layer material and that of the piezoelectric material and between the ratios of layer thickness to sound velocity for protective layer and piezoelectric layer as a frequency-relevant or frequency-determining element, the total thickness of the piezoelectric layer being less than the limit value specified in Claim 1.

Patent DE-3839627-A1 (DE)
Title: Telephone terminal
Inventor: ARMBRUESTER WERNER DIPL ING
IPC: H04M3/40
Filed: 1988-11-24
Abstract: In telephone terminals with a level-controlled balance and an echo canceller, in two-way communications between telephone subscribers, when one telephone subscriber stops speaking and the other telephone subscriber starts speaking, the initial syllables of the subscriber starting to speak are excessively attenuated. To improve initial syllable comprehensibility, a control device calculates the attenuation value produced by the echo canceller and/or the attenuation value of the echo path. The attenuators of the voice-controlled balance are activated in such a way that the sum of the attenuation values set on the attenuators and the attenuation values calculated for the echo canceller and the echo path is constant. The invention can be used, for example, in a telephone terminal with a hands-free facility.
Patent DE-3901427-A1 (DE)
Title: Method and device for the construction and reproduction of a multiple hologram
Inventor: FICKER ELMAR DR
IPC: G03H1/26
Filed: 1989-01-19
Abstract: In the construction and reproduction of a multiple hologram comprising a plurality of interferograms, the problem exists of being able to take a sequence of interferograms quickly and distinguishably on a photographic layer to be exposed or to be able to reproduce them rapidly and distinguishably from an exposed photographic layer. The multiple reference beam method customary for this purpose is too slow, at least in its known mechanical and/or optical embodiment, for a high resolution with time. The expense of generating a plurality of reference beam directions can be avoided, according to the invention, by deflecting laser light of successively different polarisation in one single reference beam direction onto the photographic layer which is to be exposed or is exposed. With such laser light of successively different polarisation, however, a multiplicity of reference beam directions can also be generated, more rapidly than heretofore, by means of polarisation splitters and Faraday rotators. The invention may be used, for example, for the analysis of spatial movement sequences or also of stochastic dynamic states.
