  • Bicycle drive train
    Patent number: 10683058
    Abstract: A multi-wheel bicycle with a dual universal joint disposed on a bicycle frame, wherein a first end of the universal joint is mounted to the bicycle frame and a second end of the universal joint is mounted on a moveable end of a bicycle steering fork. A front drive chain is couple from the universal joint to a front tire disposed on a free-wheeling front hub, and a second drive chain is coupled from the first end to a drive sprocket. The drive sprocket is further coupled to a free-wheeling hub attached to a front tire. The coupling provides for transfer of rotational power from the drive sprocket to the front and rear tires through the dual universal joint even as the universal is flexed through its range of motion while steering the bicycle.

  • Apparatus for separating a mixture of components by thin layer electrophoresis
    Patent number: 4715943
    Abstract: This apparatus comprises a magazine (18) of moulds (10) a device (50) for grasping these moulds and allowing each mould to be brought sucessively above a support (30), then above an electrophoretic cell (40). A pipetting device (20, 23) allows each mould placed on the support (30) to be filled with an electrically conductive gel and a mixture of components to be separated by electrophoresis to be introduced thereinto.Thanks to a device (70) it is possible to decelerate and measure, during electrophoresis, the relative positions of the components of the mixture and their velocity of separation in the gel.
