A method for controlling the foam produced when a molten material encounters reduced pressure in a vacuum chamber includes passing the molten material through an aging zone in the vacuum chamber in which the molten material is allowed to drain from between the bubbles of the foam and then collapsing the bubbles of the drained foam.

An electromagnetic generator without moving parts includes a permanent magnet and a magnetic core including first and second magnetic paths. A first input coil and a first output coil extend around portions of the first magnetic path, while a second input coil and a second output coil extend around portions of the second magnetic path. The input coils are alternatively pulsed to provide induced current pulses in the output coils. Driving electrical current through each of the input coils reduces a level of flux from the permanent magnet within the magnet path around which the input coil extends. In an alternative embodiment of an electromagnetic generator, the magnetic core includes annular spaced-apart plates, with posts and permanent magnets extending in an alternating fashion between the plates. An output coil extends around each of these posts. Input coils extending around portions of the plates are pulsed to cause the induction of current within the output coils.

This invention is related to glasses for use as substrates in flat panel display devices, more specifically to a family of aluminosilicate glasses in which less than 0.2 mole percent and preferably no As.sub.2 O.sub.3 is used as a fining agent and the .beta.-OH of the glass is maintained below about 0.5.

An archery bow sight is set forth which may be affixed to a conventional bow for a vertical sighting irrespective of the rotation of the bow. The bow sight includes a plurality of curved pins representing different target ranges, but with each individual curved pin being a constant distance from the axis of the arrow such that the curvature of the pins allows for the bow to be tilted without affecting accuracy.
