Title: Radially symmetric hologram and method of fabricating the same
Inventor: FELDMAN MICHAEL R
IPC: G02B5/32
Filed: 1992-11-02
Abstract: RADIALLY SYMMETRIC HOLOGRAM AND  METHOD OF FABRICATING THE SAME                 Abstract of the Disclosure A radially symmetric iterative discrete on-axis hologram has a high diffraction efficiency for a correspondingly small f-number. The radially symmetric hologram has a plurality of concentric constant radial phase fringes.  Each fringe has a predetermined plurality of radial phase rings and each fringe corresponds to a predetermined plurality of radial phase transition points and a radial phase value between the radial phase transition points.  The radially symmetric iterative discrete on-axis hologram also has radial phase fringes with a predetermined number of phase levels, at least two adjacent fringes have a phase level difference which is greater than one and less than the predetermined number minus one.  The radially symmetric iterative discrete on-axis hologram is fabricated by determining a plurality of concentric fringes of constant phase with a plurality of radial phase transition points and radial phase values between the radial phase transition points for each concentric fringe.  The plurality of radial phase transition points and radial phase values are repeatedly optimized to obtain optimized radial phase transition points and optimized radial phase values which maximize the diffraction efficiency.  A radially symmetric hologram with concentric fringes of constant radial phase corresponding to the optimized radial phase transition points and the optimized radial phase values is then fabricated using known fabrication techniques.

Patent CA-2129874-A1 (CA)
Title: Powder for Use in Thermal Spraying
Inventor: DOUGLAS RICHARD M
IPC: C23C4/10
Filed: 1994-08-10
Abstract: A powder for use in a thermal spraying coating process comprises particles consisting essentially of a metal carbide core coated at least partially with a layer consisting essentially of a nickel-chromium alloy containing the metal carbide dissolved therein.  The particles are formed by heating a mixture of fine starting particles of the metal carbide in the presence of the nickel-chromium alloy under conditions effective to cause a portion, preferably 60 to 90 wt.%, of the starting metal carbide to dissolve in the Ni-Cr alloy.  In an alternate embodiment suitable for higher temperature application, more than 90 wt. % of the starting carbide particles are dissolved.  As the amount dissolved approaches 100 wt.%, the core essentially disappears. Coatings formed according to the invention show an unexpectedly large increase in both smoothness and erosion resistance.
