Abstract: A dynamometric tool having a longitudinal axis and capable of providing a tightening torque, includes: a head with a first housing arranged along the longitudinal axis and a second circular housing arranged along a transverse axis perpendicular to the longitudinal axis, the head being adapted for receiving a dowel in the second housing; a shaft to be received in the first housing, the shaft being capable of assuming a working position in which a first end thereof is located in the second housing for engaging with the dowel. In order to make the tool fully removable, the head and the first end of the shaft are arranged and sized so that the head and the shaft can assume a first relative orientation in which the shaft can slide freely relative to the head so that the head can be removed from the shaft, and a second relative orientation in which bearing members are arranged so as to maintain the shaft in the working position.

Abstract: The present invention relates to a dynamometric tool for medical use with a longitudinal axis AA comprising: a hollow grip (10) including an interior wall having a succession of recesses (29) oriented along the axis AA and the section of which is egg-shaped, an instrument holder (30) to be secured in rotation with an instrument configured to cooperate with an object to be screwed, said instrument holder being extended by a shaft (18) with an axis AA pivoting inside the grip. The instrument holder (30) is frictionally connected to said grip using a plurality of elastic members (2) arranged between said shaft (18) and said grip (10), each elastic member (2) comprising a plurality of blades (4) arranged primarily along non-radial directions and elastically deformable along an essentially radial direction, the ends of the blades forming skids designed to cooperate with said recesses (29) of said interior wall.

Abstract: A transfer system comprising a closed rail circuit and pallets circulating on the rails of the circuit. Each pallet comprises at least two wheels which are designed to be supported by the rails of the circuit and are driven by a belt. The respective wheels comprise an axle to which a first roller is mounted and a second roller is rotatably mounted on the periphery of the first roller by a bearing. The system reduces the wear of the drive belt and the rollers when the pallet is stationary by permitting the first rollers to be rotated by the continuously moving belt when the pallet is stopped.
