Title: Force-transmission unit comprising speed-dependent hydraulic clutch and centrifugal force compensation
Inventor: GRATZER FRANZ
IPC: F16D43/10
Filed: 2000-12-07
Abstract: The invention relates to a force-transmission unit, comprising a hydraulic clutch which is dependent on the difference in rotational speed. The unit ha s a housing (4) and is characterised in that a hydrostatic displacement machin e (20) generates a pressure in a pressure chamber (34), if a difference in rotational speed occurs between the input member (1) and the output member (6), said pressure acting upon a piston (27) which impinges upon a friction clutch (31). In order to compensate the centrifugal force which acts upon th e service fluid in the pressure chamber (34), at least one centrifugal force element (11, 12, 13) is located in the housing. Said element exerts a force on the piston (27), which opposes the pressure generated by the centrifugal for ce in the pressure chamber (34).

Title: Method and apparatus for estimating solvation energies of membrane bound molecules
Inventor: SPASSOV VELIN ZLATKOV
IPC: G06F19/00
Filed: 2002-07-23
Abstract: The disclosure relates to a method of estimating the polar component of the solvation energy for a molecule embedded in different media. In one embodiment, the molecule is partially embedded in a membrane. For an atom of the molecule, the polar component of the atom's solvation energy is represented as a combination of at least a self energy term and a screening-effect term. The self energy term represents the contribution to t he atom's polar component made by the membrane and the molecule's other atoms located inside  the membrane. The screening-effect term represents the typically negative contribution to the atom's polar component made by the molecule's other atoms located outside th e membrane. An analytical function is used to calculate the self energy term. In a preferred embodiment, the analytical function is a function of the distance from the atom to the membrane, the van der Waals radius of the atom, and the thickness of the membrane. The effecti ve Born radius of the atom is then determined based on its polar component. The effective Born radii of the atoms are then used to determine the polar component of the solvation energy  for the molecule.

Title: Controlled and sustained release properties of polyelectrolyte multilayer capsules
Inventor: VIEIRA EURIDICE
IPC: A61K9/52
Filed: 2001-08-28
Abstract: Method of layer-by-layer (LbL) assembly of oppositely charged polyelectrolytes was applied to coat fluorescein particles. These particles with a size of 4-9 µm were prepared by precipitation of fluorescein at pH 2.  Polysterensulfonate (PSS) and polyallylamine (PAH) were used to compose the polyelectrolyte shell on the fluorescein core. The release of fluorescein molecules through the polyelectrolyte shell core dissolution was monitored at pH 8 by increasing fluorescence intensity. The number of polyelectrolyte layers sufficient to sustain fluorescence release was found to be 8-10.  Sequentially adsorbed layers prolong core dissolution time for minutes. The permeability of polyelectrolyte multilayers of the thickness of 20 nm is about 10-8 m/s. Mechanism of fluorescence diffusion and osmotically supported release is under discussion. The features of release profile and possible applications of LbL method for shell formation in order to control release properties for entrapped materials are outlined. Also ambient conditions of pH, temperature and salt concentration were changed to control the permeability of polyelectrolyte multilayer capsules.
