Abstract: So that a pivoting part (12), for example the window or roof light of a vehicle, can be swung out and retained in a specific position, there is arranged between the pivoting part (12) and a receiving part (16) at least one guide rail (22) with an approximately longitudinally extending groove (52) having at least one indentation (54). The guide rail (22) is pivotably mounted at one end on one of the parts (12, 16). It receives slidably in its groove (52) a pin (48) connected to the other part (12, 16). Furthermore, a block (24) displaceable along the guide rail (22) is provided. This is so designed that, as a rule, it covers the indentation (54) of the guide rail (22) and exposes it only in a retention position. In the retention position, the pin (48) can engage into the indentation (54) of the guide rail (22) and be supported on a side face (58) of the indentation (54). During the opening or closing of the pivoting part (12), the block (24) is displaced on the guide rail (22) as a result of the engagement of the pin (48). Arranged between the pivoting part (12) and receiving part (16) in parallel with the retaining device (18) is a pneumatic spring (20) which endeavours to bring the pivoting part (12) into an opened position.

Title: Recovering combustion heat from organic components in liq. - using interconnected indirect heat exchangers
Inventor: KURZ GERMAN
IPC: F23J15/06
Filed: 1989-08-10
Abstract: After the combustible components, esp. the organic materials in liq. such as sewage or salt soln. have been thermally oxidised in a chamber contg. a burner, hot combustion gases are discharged into water or aq. soln.

Patent DE-3927516-A1 (DE)
Inventor: STILLER CHRISTOPH DIPL ING
IPC: H04N19/537
Filed: 1989-08-21
Abstract: In conventional moving-image encoders, image areas are displaced block by block and it is not taken into account whether moving or unmoving image content exists within such blocks. In the process according to the invention, moving image contents are detected with the aid of an object mask and displaced independently of the surrounding unmoving image background. Instead of a block-oriented predicted image, an object-oriented predicted image is determined. For this purpose, shape and type of the moving image content is determined in the receiver from the motion information normally transmitted and the conventionally decoded image sequence and stored in an object mask which continuously tracks moving objects. Using this object mask, an improved display image can be generated by copying the image background from an image store. The method according to the invention leads to a qualitatively improved reproduction of coded moving-image sequences. In addition, intermediate images can be generated in which moving image content is also displaced independently of the image background.
