Title: Conveying line stop for workpiece or pallet moves against spring to stop and re-sets by spring being held at stop by inbuilt bolt for dependability.
Inventor: JUNG NORBERT
IPC: B65G47/88
Filed: 1998-07-18
Abstract: The stopping element (2) moves into its stop position against a spring (11) which in turn re-sets the element to its starting position. In its stop position the element remain locked by bolt (21) until released as the element rides out of the object conveying section. The bolt (21) is spring-mounted in a housing (8) and reaches into the path of the stop element (2) so as to free this in response to the movement of the stop. As the stop moves from start into stop position, the bolt (21) moves with pre-tension relative to the stop face so as to project in front of this in the stop position. As the stop moves into its free position, so the bolt (21) enters the section of a hole in the stop which is then moved by spring (11) into the start position as before. The stop (2) has an L-shaped groove (32) whose leg (33) is as long as the stop-to-start interval distance and retains constant section (33). The other leg of the groove, also as long as this specified interval distance, decreases steadily in depth right down to the groove shoulder end.

Patent DE-19834430-A1 (DE)
Inventor: MELCHNER HARALD VON
IPC: C12N15/867
Filed: 1998-07-30
Abstract: The invention relates to vectors for cancer therapy which as a result of genetic differences between normal and transformed cells selectively eliminate the latter. This is made possible by integrating a sequence-specific recombinase into a viral or non-viral expression vector, whose expression is controlled by a transcription factor which has mutated in tumour cells and is therefore inactive, as well as by a suicide gene which is flanked by at least one recombinase-specific target sequence. Through the transcription-factor-mediated activation of the sequence-specific recombinase the vector is eliminated from untransformed cells together with the suicide gene. The vector is, however, not eliminated from tumour cells in which the transcription factor is not active and expresses the suicide gene in said cells. After contact with a corresponding prodrug these cells are selectively killed off.
