Title: Desiccant bag for oil and other liquids
Inventor: JUNG WILLI DR
IPC: B65D81/26
Filed: 1987-03-30
Abstract: Desiccant bag having a holding string, filled with highly hygroscopic substances, which very highly reliably remove water and water traces from oil or other liquids and store the water in order to prevent consequential damage. This desiccant bag is regularly exchanged before its capacity is completely exhausted. To safeguard against damage by sharp cut edges etc. and for improved handling, the desiccant bag can be accommodated in a closable hard box, by means of which, especially, the bag is also prevented from being sucked fast against the suction orifice. This hard box is made to be completely liquid-permeable by an expedient arrangement of holes. The desiccant packed into the bag is a substance which completely retains the hygroscopic capacity in the medium to be treated, such as, for example, oil or diesel fuel, and therefore removes water and traces of water from the liquid. Thus, specifically, above all in steel tanks, the formation of rust and pitting corrosion is prevented. The hygroscopic substance is a polyacrylate or another commercial highly water-absorbing material.

Title: Variable speed drive for bicycle - uses V=belts and split pulleys to produce stepless variation of speed ratio
Inventor: WOLLENSCHNEIDER ERNST
IPC: B62M25/04
Filed: 1989-05-05
Abstract: The bicycle is propelled by cranks (4) which rotate a pulley (6) with a groove for a V-belt (8). The V-belt (8) drives the variable speed device (20) which drives the rear wheel by means of a second V-belt (14). The variable speed device consists of a cage (23) which can move horizontally on two parallel guides. This cage (23) supports a shaft which carries two discs with conical faces which are separated by a third disc with a conical face on both sides so that the three discs form two V-grooved pulleys mounted side by side. As the cage (23) is moved horizontally the increased tension in one or other of the belts (8, 14) forces the central disc sideways. This increases the effective dia. of one pulley and reduces the dia. of the other and so alters the overall ratio of the drive. USE - Variable speed drive for bicycle.
