摘要： A glass tube for use in an optical fiber preform is produced by applying a first soot on an end face of a starting member to form an elongated, porous cylindrical soot core having a first density, and applying a second soot including SiO2 on the periphery of the soot core to form a porous soot cladding having a second density greater than that of the soot core at the periphery of the core. The core and the cladding are later heated together at a temperature sufficient for sintering to form a core glass and a cladding glass. Because the soot core collapses at a greater rate than the soot cladding during sintering, the core glass separates or delaminates radially from the cladding glass. The core glass is then removed from the surrounding cladding glass, and the latter is treated to provide a high purity glass tube suitable for use as part of an optical fiber preform.

摘要： An electric jack for receiving an electrical plug having two discrete electrical contact portions and establishing an electrical connection therebetween. The jack comprises in combination a housing having an electrical plug receiving chamber, a plug tip reservoir purposed to contingently receive broken or otherwise separated portions of a previously inserted plug, an access/egress aperture communicating with the chamber for insertion therethrough of the electrical plug, a plurality of compressible, partially cylindrical contacts each having a circuit contact section and an electrical plug contact section and housed within the receiving chamber, with pin contacts positioned generally perpendicular to the base of the jack along opposite sides of the receiving chamber.

摘要： The finger-mounted striking devices described herein are for use on stringed musical instruments, in particular for but not limited to electric or acoustic bass instruments. The paired devices consist of elongated cylindrical wooden shafts of differing length. The offset in length allows the striking tips to be effectively even when worn as intended on the index and middle fingers. The striking tip of each shaft contains a permanently embedded weight to accelerate the transfer of finger movement to the shaft tip. The mechanism for attaching the elongated shaft to each finger is an adjustable metal ring permanently attached to the shaft end opposite the striking tip. An upward-sloped fingertip rest is provided forward of the ring. The entire body of each elongated shaft and the integral metal ring are encased in an elastomeric coating that prevents scratching of the instrument surface during use by the devices and seals the metal ring against corrosion from moisture. Additional layers of elastomer coating are added to the striking tip to eliminate impact damage to the outer windings of instrument strings.
