Title: Chain mfr. using carousel-type machine - involves three 90 deg rotations of four armed carousel followed by 270 deg reverse rotation to avoid twisting up chain
IPC: B21L3/00
Filed: 1992-11-21
Abstract: The machine is used for mfr. of round-link or oval link chains, esp. chains made of steel. There are four working stations (A,B,C,D), spaced equiangularly and equidistantly from the vertical axis (6) of a carousel with four arms (9) of equal length.

The carousel makes three 90 deg. turns and then turns back through 270 deg. to return to its starting point and begin another complete cycle. The chain (5) may be lifted up by the length of one link at this point. USE/ADVANTAGE - Carousel-type chain mfr. machine works on four chains simultaneously, performing equivalent of successive 90 deg. steps between workstations but without twisting chains up.

Title: Sealing arrangement for ship hatch covers
Inventor: TOENJES ULRICH DIPL ING
IPC: B63B19/26
Filed: 1994-02-07
Abstract: The invention relates to a sealing arrangement for ship hatch covers which has an elongated sealing strand (13) arranged in a mounting profile (12). The sealing strand (13) assumes a sealing position due to its inherent stability. The sealing strand (13) can be put into an opening position of lower height by applying a vacuum to an airtight hollow space (27). The connection between the sealing strand (13) and the mounting profile (12) has been found to be problematic here. This is because the deformation required to draw the sealing strand (13) into its opening position can lead to the sealing strand (13) being released from the mounting profile (12). According to the invention, the sealing strand (13) is connected to the mounting profile (12) by releasable retaining means (14) between the sealing strand (13) and the mounting profile (12). As a result of their releasability, the retaining means (14) can be provided with such a large cross-section that on the one hand they can be assembled and dismantled without problem but on the other hand they guarantee reliable retention of the sealing strand (13) in the mounting profile (12). <IMAGE>
