Title: Liquid level sensor for ink jet printers
Inventor: SHARPE COLIN RICHARD
IPC: G01F23/24
Filed: 1995-09-14
Abstract: The ink level sensor of the invention comprises an ink container (46) having a generally cylindrical shield (56) extending downward from its top to define sheielded and unshielded compartments (52, 54) within the container (46). Ink, but not foam, froth or mist, flows under the shield (56) to the shielded compartment (52). A plurality of conductive rods (66,68,70,72) of differing lengths extend downwardly into the shielded compartment (52) from the container top. The rods are connected to an impedance network (48) which provides signals representative of the ink level inside the container (46). A vacuum source (42) can be connected in each compartment to maintain pressure equilibrium in the compartments (52, 54) and to prevent foam, froth or mist from entering the shielded compartment (52). Alternatively, a return pump is used to force ink into the container (46) such that each compartment can be vented to the atmosphere.

Title: Sugar modified nucleosides and their use for synthesis of oligonucleotides
Inventor: SEIFERT WILFRIED
IPC: A61K31/7064
Filed: 1995-11-02
Abstract: A number of modified nucleosides are disclosed composed of modified sugar moieties which contain substituents at C1 and C4 positions, or branched substituents at C3 and C5 positions of deoxyribose or ribose. Each nucleoside is converted to or properly protected and them converted to the corresponding phosphoramidites. These phosphoramidites are used to assemble oligonucleotides in which there is at least one of the forenoted nucleosides. These sugar modified oligonucleotides have the potential to be used as antisense therapies since they are expected to enhance nuclease resistance and cellular uptake while they maintain sequence-specificity and affinity to nucleic acid targets in vitro or in vivo.
