An insulating coating of a desired portion of an electric cable is removed by selectively irradiating the desired portion with a pulse laser beam having a pulse width of 5 mu sec or less and a peak output of 1 MW or more.

A field emission source is used in conjunction with a three element asymmetric lens system to provide an electron gun having greater magnitude beam currents focused on a smaller spot size than has been previously possible for intermediate energy beams. The three element asymmetric lens system has a lower spherical aberration than prior art electrostatic guns and a very low chromatic aberration coe...

FLAME RETARDANT POLYURETHANE FOAMS A polyurethane foam contains, as a fire retardant, water-soluble silicate particles in an amount of at least 30 parts per 100 parts by weight of the polyol of the polyurethane, which silicate particles have an average size of at least 62 microns.

Crosslinking polyamide oligomers are mixed with comparable, noncrosslinking, polyamide polymers to provide solvent-resistant blends that are particularly suited for aerospace uses. Generally, the blend comprises an equimolar mixture of the linear or multidimensional oligomer and a polymer having substantially an identical backbone and substantially the same average formula weight as the oligomer. ...

Compositions which cure by UV radiation in less than one second are obtained by mixing an alkenyl containing polydi- organosiloxane, a mercapto functional crosslinker of the mercapto functional polyorganosiloxane or mercapto organic compounds, a photosensitizer, a viscosity stabilizer, and optionally a reinforcing agent. These compositions can be packaged in one container and can be used as the pr...

Water draining from a septic tank contains ammonium, which traditionally is oxidized to nitrate in an aerobic soakaway. When the effluent enters the groundwater, the resulting nitrate concentration can be troublesome. A body of organic carbon, e.g. wood chppings, is provided, and the nitrate-laden effluent is passed through the carbon. The carbon is placed in the ground so as to be anaerobic: for ...

The appts. to form a coating on flat glass in a vacuum deposition process, especially to apply a layer of indium-tin-oxide has a gap (a) between the target (3) and the cathode (5). Tie rods or holding pins (30,30') act as holders for the target (3) as a bond to the cathode body, such as the magnet yoke (6) or the U-shaped component (4). ADVANTAGE - The appts. prevents the formation of pimples on t...
