Anchor escapement is, an increase in amplitude of swing causes a slight increase in period of a pendulum due to circular error, and that this can compensate for the decreased period due to isochronism. Due to this effect a carefully adjusted anchor escapement with polished pallets might be more accurate than a deadbeat. This has been confirmed by at least one modern experiment. Anchor escapement In horology, the anchor escapement is a type of escapement used in pendulum clocks. The escapement is a mechanism in a mechanical clock that maintains the swing of the pendulum by giving it a small push each
Osmotic-controlled release oral delivery system Osmotic-controlled release oral delivery system The osmotic-controlled release oral delivery system (OROS) is an advanced controlled release oral drug delivery system in the form of a rigid tablet with a semi-permeable outer membrane and one or more small laser drilled holes in it. As the tablet passes through the body, water is absorbed through the semipermeable membrane via osmosis, and the resulting osmotic pressure is used to push the active drug through the opening(s) in the tablet. OROS is a trademarked name owned by ALZA Corporation, which pioneered the use of osmotic pumps for oral drug delivery. Osmotic release systems
