Title: Labelling arrangement for destination keys on communication terminals
Inventor: NIEDERHOEFER KARL-HEINZ DIPL I
IPC: H04M1/2748
Filed: 1988-08-19
Abstract: A labelling arrangement is to be presented which can be labelled without aids from the communication terminal, no labelled pieces of paper needing to be exchanged when a change is necessary. The labelling fields are constructed as electrically selectable display fields which additionally exhibit activatable symbols in their edge zones. This signals a correlation with the associated destination key. During a programing phase, which can be carried out by the subscriber, for inputting dialling information, letters appear in the edge zones so that the destination keys are used as an alphabetic keyboard for writing in names and designations which are to be allocated to the individual destination keys. The labelling arrangement for allocation keys on communication terminals enables a user to label each display field individually without aids. In particular, changes can be carried out directly from the terminal by simple operating procedures.

Title: Arrangement for the laboratory-independent determination of the normal-stress-dependent shear stress and of the associated shear displacement in undisturbed and disturbed soil samples
Inventor: WAGNER PETER
IPC: G01N33/24
Filed: 1989-02-22
Abstract: The invention relates to an arrangement for the laboratory-independent measurement of the shear stress under the influence of a defined normal stress and the determination of the associated shear displacement in undisturbed and disturbed soil samples on site, in the field. For determining these variables, the soil sample to be examined is loaded with a defined normal stress in a coring cylinder (1). One or more winged rotational bodies (10) having torque measuring devices connected to it (them) is (are) guided into the soil sample and shear(s) the sample. The torque maximum occurring yields the maximum shear stress, taking into account the diameter of the winged rotational body. The determination of the shear displacement is carried out by measuring and converting the shear angle between the beginning of the measurement and the stress maximum.

Title: Multiplexing of optical signals of different wavelengths - using wavelength selective element to identify signals for bidirectional transmission
Inventor: BIALAS JOACHIM DR
IPC: G02B6/34
Filed: 1989-09-05
Abstract: An optical fibre transmission system (LWL) has signals with different wavelengths (L1,L2,L3) received by a wave length selective element (WE). The signals are partially transmitted and reflected (RL) onto the reflecting surface (SP) of a mirror. The wave length selective element can be in the form of a Fabry-Perot element, where the optical component (Lm) is selected on the basis of a specific angle of incidence (Am).  Receivers (E1-E3) are located at specific intervals to detect the presence of components and so performs a demultiplexing operation. Signals from transmitters (S1-S3) can be multiplexed into the optical fibre in a inverse process. ADVANTAGE - Simple and compact method of multiplexed signal handling.

Patent DE-3932837-A1 (DE)
IPC: B01F23/10
Filed: 1989-09-30
Abstract: In dryers with gas heating, it is a particular problem uniformly to mix the combustion gases produced with the burner with the treatment air which is circulated in the circuit. In order to achieve this, a special construction of the air mixing device is envisaged, which consists of three parts arranged one behind another, the treatment air being in each part of different construction in each case deflected to the centre of the treatment duct and in this connection mixed with the air flows which originate from the sides. It is advantageous, firstly by means of a funnel-shaped air mixing part and then by means of such with sheets arranged parallel to one another, which are first arranged vertically and then transversely thereto, to create swirling in each case.

Title: Support rails for adjustable seat mounting - has stamped tooth profiles and with grip of folded spring steel
Inventor: THIEL PETER
IPC: B60N2/08
Filed: 1989-10-24
Abstract: The seat mounting has a pair of support rails under the seat sliding on support rails mounted on the floor of the vehicle.  Both rails have corresponding tooth profiles (6,9) stamped into their shapes and with the tooth gaps coinciding for a locking action.
