Title: Magnetically-operated lock mechanism - has locking plate cooperating with pivoted latch engaging door catch
Inventor: VADACCHINO JOSEPH
IPC: E05B47/04
Filed: 1989-12-21
Abstract: The magnetically operated lock mechanism has a metal housing (5) enclosing a pivoted latch (4) selectively brought into engagemetn with a door catch.

Patent DE-4003781-A1 (DE)
Inventor: PISCHKE JUERGEN DIPL PHYS
IPC: B60G17/016
Filed: 1990-02-08
Abstract: In a height regulating system for a vehicle having an air spring suspension, the actual value (h) of the vehicle body (10) is filtered with a short time constant (t1) of 0.4 sec to produce a first signal (NIV1) which is compared with a desired height (h0). The actual value (h) is also filtered with a longer time constant (t2) of 2-3 secs to produce a second signal (NIV2) which is compared with the desired value (h0). In a first mode following an adjustment of the desired height (h0), the first signal (NIV1) smoothed with the short time constant (t1) is compared with the newly adjusted desired height (h0) and a height regulating operation is carried out without any delay. As soon as the second signal (NIV2) smoothed with the longer time constant (t2) reaches the desired height (h0), the second mode commences in which height regulating operations are carried out only after a long delay (td) of 15-25 secs. In the second mode, the system may respond to the first signal (NIV1) or the second signal (NIV2). <IMAGE>
Patent DE-4007369-A1 (DE)
Inventor: BUSCH JUERGEN
IPC: B44C1/17
Filed: 1990-03-08
Abstract: A method for transferring a pattern onto a decorative film, comprising an organic material such as polyvinyl fluoride, in particular for the interior of an aircraft cabin by the transfer printing process. In this method, for transferring the pattern, the decorative film is brought into close contact with a pattern carrier, which contains the pattern formed by organic dispersive dyes, contact being established by pressing with a textured mat in between, and transfer of the pattern taking place by diffusion when heat is applied. The invention consists in that the decorative film (2) to be printed has a textured surface and the colour transfer takes place at a temperature at which essentially there is still no plastifying of the film surface and the textured mat (4) consists of such a compliant material that, when pressure is applied, the pattern carrier (3) comes into close contact with the decorative film (2) even in the depressions of the texture. 
<??>In this case, it is particularly advantageous that not only photographically recorded patterns but also the line patterns hitherto applied by screen printing can be transferred in this way to the films and consequently to the structural members and reductions in cost are obtained by virtue of the fact that the pattern carriers of paper can be produced more advantageously by the rotary process than by the screen printing process.

Title: Fibre-reinforced body prodn. - by winding slivers of parallel fibre coated in matrix material to prevent fibre breakage
Inventor: DUDEK HANS JOACHIM DR
IPC: B29C53/56
Filed: 1990-07-06
Abstract: At least one fibre coated with a matrix material is wound round the body which is then covered by a capsule to be evacuated and heated to give a high pressure on all sides.

Fibres (20), coated with the matrix material, have a layer of adhesive to hold a fine grain powder material round the fibre surfaces before the sliver is wound round the carrier body (18). ADVANTAGE - Method prevents fibre breakage during winding and also during the hot isostatic press stage.
