Title: Surgical drain eccentric locking mechanism - has male and female portions with bores eccentric to instrument axis
IPC: A61M25/02
Filed: 1973-08-03
Abstract: The mechanism is particularly for use with a catheter inserted in a body cavity, and comprises a pair of safety devices mounted on the oblong body, one with a protruding male portion and the other having a hollow portion in which it fits. The male and female portions can be rotated in relation to each other, each having a circular through passage concentric to the other through which the portion is inserted to secure the device on the body. However the passages are eccentric to the centre line of the male portion and the hollow body, so that the safety devices cannot turn right round it. When one of them is rotated, the body and the passage walls are forced into frictional contact, thus preventing displacement.

Patent FR-2358488-A1 (FR)
Inventor: THEIHSEN HANS
IPC: D02H3/00
Filed: 1976-08-24
Abstract: The threads coming from a bobbin creel are wound in band form onto a warping drum (12). The warping drum (12) is displaced laterally relative to a guide reed of the threads by a feed drive (81) in dependence on an increasing winding thickness. The increasing winding thickness is sensed by a sensing member (29). In order to warp coarse and fine threads uniformly also within adjacent bands, the increase in the winding thickness is sensed only on the first band. The rest of the first band and/or the further bands are warped according to the measured average value of the increase in the winding thickness, without the actual increase in the winding thickness being taken into account.
