Title: Lighting control for bicycle - has dynamo driven off crank-wheel with battery back up
Inventor: FENNER KLAUS DR
IPC: B62J6/06
Filed: 1980-02-22
Abstract: The bicycle lighting control has the dynamo (12) driven directly off the crank wheel and coupled to the lights via a control circuit and a rechargeable battery (10). This ensures that the lights operate when the machine is stopped. The direct drive prevents any loss in torque when the wheels are covered with ice or water. The dynamo is mounted on the frame behind the crank wheel and has a direct drive gear meshing with the crank wheel. An alternative design has the dynamo incorporated inside the crankcase, with the rotor mounted on the crankshaft. A manual override switches off the lights, to save the battery, if the machine is stopped for long periods.

Title: Rig for a wind-surfboard
Inventor: HOERNSCHEMEYER HEINZ ING GRAD
IPC: B63B35/79
Filed: 1981-01-08
Abstract: The main application relates to a novel rig for wind-surfboards which comprises a mast and a boom of the length of the mast, on which the sail is held. The mast and boom are supported above the joint of a foot on the latter and thus on the wind-surfboard, for which purpose the top end of the foot is forked. A spar keeps the mast and boom spread in the position of use and thus keeps the sail stretched. In order to facilitate the erecting and dismantling of the rig and to reduce the time needed for this purpose, is it proposed to form the branching end (forming the fork) of the foot from two parts which are held in a fixed manner relative to one another in the position of use of the rig. Figure 1 shows a simple exemplary embodiment of a push-in connection with the two parts 5 and 6 forming the fork. <IMAGE>

Abstract: A drawing-in and drawing-out device for drag cables of drag lifts is provided with a restoring spring for the drag cable drum, on which the drag cable is wound up, and with a centrifugal brake for the drag lift drum, having at least one centrifugal weight. The distance between the axis of rotation of the centrifugal weight and the region of application of the centrifugal weight on a housing inner wall, preferably provided with a brake lining, of the drawing-in and drawing-out device is automatically variable, in dependence on the sense of rotation of the drag cable drum, in such a way that the point of application of the centrifugal weight is closer to the axis of rotation of the centrifugal weight during drawing-out of the drag cable than during drawing-in of the drag cable. In order to achieve an adequate difference in the braking action during drawing-out of the drag cable in comparison with drawing-in, without adversely affecting the stable mounting of the centrifugal weight, the centrifugal weight has in its region remote from the axis at least one brake shoe, mounted such that it can swivel between two stops about an axis parallel to the axis of rotation of the centrifugal weight, and in its region near to the axis a preferably cam-like projecting brake surface. <IMAGE>
