Inventor: WEISS GISBERT
IPC: D06Q1/00
Filed: 1989-11-24
Abstract: The invention relates to a process for the embossing of textiles, in which mutually adjacent layers of a textile material and of a film material are pressed between two mutually opposite embossing surfaces under the effect of heat and are bonded to one another. Such known pressing processes produce embossings which are not dimensionally stable to an adequate extent during washing, ironing and drying of the textile material. The invention is aimed at an embossing process by which dimensionally more stable embossings can be produced. The process according to the invention is characterised in that a foamed film is used as the film material and the foamed film is compressed differently in different regions of its surface in order to form an embossed pattern. <IMAGE>

Patent DE-4009103-A1 (DE)
Inventor: GALLENMILLER CLAUS PETER
IPC: G09B5/06
Filed: 1990-03-21
Abstract: In order to induce and maintain a relaxed state in human beings while a learning programme is being transmitted, right and left multiplex signals (MR and ML) recorded on a sound carrier are obtained and amplified in a reproducing device. Audio signals and frequency-modulated control signals are derived from these amplified multiplex signals by means of suitable filter stages (66, 68, 70, 72). The frequency-modulated control signals are demodulated, amplified and used to activate a light source (20; 22), and the audio signals are made acoustically perceptible by means of headphones (16, 18). The light signals and some of the audio signals produce the relaxed state of the subjects; the other audio signals are used to transmit information. As the control signals are recorded on the sound carrier while the learning programme is being recorded, the control signals can be co-ordinated with, i.e. matched and adapted to, the instantaneous information content of the learning material.

Abstract: 2.1 Test devices for earth-fault circuit breakers have the object of closing an auxiliary circuit when a test button is operated, in order to be able to test the operation of the earth-fault circuit breaker. In this case, it must be ensured that the auxiliary circuit cannot be closed in the switched-off state. 2.2 The invention indicates a means by which a test device is combined with an auxiliary circuit and a test button (7) having a contact position display device (6), a switch shaft (1) which is connected to the moving contact (2) additionally being equipped with a bending spring (4) which is used not only as an operating device for the contact position display device (6) but also makes contact with a contact spring (5) of the auxiliary circuit when the contacts (2, 3) are closed. When the contacts (2, 3) are opened, the contact spring (5) cannot make contact with the bending spring (4), so that the auxiliary circuit remains opened even if the test button (7) is operated. 2.3 The test device can be used in all types of earth-fault circuit breakers, but is particularly suitable for earth-fault circuit breakers of narrow construction. <IMAGE>
