Title: Wave-shaped ac arc for lensing system
Inventor: FANNING JOHN W
IPC: G02B6/255

Granted: 1992-11-03
Abstract: J. W. Fanning - 1 WAVE-SHAPED AC ARC FOR LENSING SYSTEM                 ABSTRACT OF THE DISCLOSURE A  system  is  provided for forming an end of an optical fiber  into a lens, using a high frequency AC electric arc of predetermined   frequency,   which  avoids  the  creation  of harmonic  frequencies  that  could degrade the finished lens. An  arc  is established between a pair of electrodes, wherein the   arc   current  varies  substantially  sinusoidally,  to minimize  the  amplitude  of  harmonic  frequencies.  Voltage pulses  are delivered to a primary of a transfomer, while the secondary  of  the transformer is coupled through a capacitor to  one electrode, and the other electrode is coupled back to the  secondary  of  the  transformer.   The inductance of the secondary  winding  plus  the  reflected  inductance  of  the primary  winding, when combined with the capacitance, results in a  resonant  circuit, which generates a sinusoidal output when  excited  at  its  resonant frequency.  The square waves inputted  to  the  transformer  primary  are  at  a frequency approximately   equal   to  the  resonant  frequency  of the resonant circuit.

Title: Method and apparatus for extruding of light weight metals such as aluminium
Inventor: BAUMANN HANNES
IPC: B21C29/00
Filed: 1988-03-01
Granted: 1993-05-18
Abstract: ABSTRACT OF THE DISCLOSURE.       To increase the extrusion speed              for extrusion of light-weight metal such as aluminum, without incurring hot short cracks, or fissures, and retaining high-quality smooth surface of the extruded material, the region of the extrusion chamber immediately ahead of the extrusion die (3) is cooled by placing a cooling ring (12, 12') between the bore (9) of the extrusion cylinder in which the ram piston (13) operates.  The cooling ring may be a unitary structure, or a multi-part structure, in which an independent inner ring is located  within a cooling ring (12).  For mechanical strength, a prestressing       outer ring (20) is shrink-fitted around the cooling ring.  The outer ring is retained, for example by screws (24), on the cylinder (2) within which the extrusion chamber (9, 10) is located.          The cooling fluid may be water, a vaporizable liquid, or a gas, and is separated from the billet (1) within the extrusion chamber.

Abstract: Abstract of the Disclosure High Temperature Metallic Gasket A metallic gasket is provided for sealing a joint between first and second surfaces subjected to high pressure and high temperature.  Other gaskets used to seal such joints are of a fibrous composition held together by a suitable bonding agent and a deformable elastomer coat or bead.  Many of these gaskets used for high pressure and high temperature use an asbestos sheet which is regarded as toxic and unsafe to handle.  The present gasket is comprised of a substantially non-compressible sheet and pair of seals made from a ductile material connected to opposite sides of the sheet.  The sheet and seals are positioned between the surfaces to be sealed and the seals conform to the surface finish topography of the surfaces when a predetermined compressive load is applied between the surfaces resulting in a positive sealed joint suitable for high pressure and high temperature.
