Abstract: A METHOD OF MAINTAINING ADEQUATE SEED CRYSTAL     IN PREFERENTIAL PRECIPITATION SYSTEMS                   Abstract of the Disclosure A method for ensuring an adequate amount of seed crystal in solution concentration systems employing preferen-tial precipitation to control scaling and fouling over relative-ly low concentration factors.  In systems concentrating solu-tions at concentration factors between 1 and 2, the method com-prises determining the minimum amount of seed crystal necessary for the solution being concentrated at a concentration factor of about 10 or greater and introducing into the feed solution a percentage of this amount according to the equation:     % introduced = 25 x (C.F.) x (C.F.MAX/(C.F.MAX-1).

Abstract: ABSTRACT OF THE DISCLOSURE     A method of making self-supporting ceramic composite structures having filler embedded therein includes infil-trating a permeable mass of filler with polycrystalline ma-terial comprising an oxidation reaction product obtained by oxidation of a parent metal such as aluminum and optionally containing therein non-oxidized constituents of the parent metal.  The structure is formed by placing a parent metal adjacent to a permeable filler and heating the assembly to melt the parent metal and provide a molten body of parent metal which is contacted with a suitable vapor-phase oxi-dant.  Within a certain temperature region and optionally aided by one or more dopants in or on the parent metal, mol-ten parent metal will migrate through previously formed oxi-dation reaction product into contact with the oxidant, caus-ing the oxidation reaction product to grow so as to embed the adjacent filler and provide the composite structure.

Abstract: Abstract of the Disclosure A method  for  matching  hardcopy color to display color  for registered-dot ink-jet copiers. Video RGB is converted  into  chromaticity  coordinates in XYZ color space.  An  explicit solution is achieved by defining a new  MSW  color  space  which  restricts  the  hardcopy colors   to  some  percentage  of  one  of  the  binary Mixtures  of inks, some percentage of one of the Single inks,  and  some  percentage  of paper White. The color data  in  XYZ  space  is converted  to  MSW  space and unreachable  colors  are  mapped into reachable colors. Correction     for    hardcopy    non-linearities    is accomplished  by  considering the interaction among the inks  by  using  a  coverage ratio to correct for color shifts.  The  MSW  values  are,  thus, converted to CMY values  which  are  sent  to  an  appropriate dithering algorithm for conversion into dots on the paper.

Abstract: ABSTRACT OF THE DISCLOSURE             A Fourier transformation imaging technique is used for NMR imaging.  Spins in a selected plane are excited by selective RF pulses and an associated Gz gradient and the selected spins are subjected to three mutually orthogonal gradients which provide the resonance signal with spatial resolution along each axis produced by phase encoding.   The signals sampled and read out in the presence of a readout gradient are associated with spatial frequencies determined by the applied gradient fields.  The Fourier transformation of the spin echo signals obtained from repetition of the pulse sequences gives a two-dimensional image.   The linear phase-encoding gradient is applied starting with a preliminary phase-encoding gradient which maximizes the spin-echo signals.

Abstract: LONG WAVELENGTH OPTICAL FIBER COMMUNICATION AND SENSING SYSTEMS     Abstract Optical communication and sensing systems are disclosed which operate at long wavelengths, i.e., wavelengths greater than about 2µm, but less than or equal to about 11µm.  Each of these systems includes an optical fiber having material, such as a metal halide glass, which is substantially transparent to long wavelength electromagnetic radiation.  These optical fibers exhibit reduced microdeformation and macrobending losses, as well as low total dispersions, at the long wavelengths.  In contrast to currently held beliefs, this is achieved by using fiber designs involving relatively small relative refractive index differences, which are readily manufacturable and which avoid undesirable crystallization at core-cladding interfaces.

In the self-regulating no-load protected electronic ballast system 10 there is a filter circuit 11 which is connected to the power supply source 12 by an induction circuit 15 which is connected to the filter circuit 11. The induction circuit 15 has a primary winding 42 with an outlet whereby a balancing transformer connection is created for determining the regulated current. The induction circuit 15 comprises a control winding 48 to achieve a control current and a no-load protection circuit 99 for the creation of a voltage across the vapour discharge tube 66 which is dependent upon the regulated current and for maintaining the output voltage at a predetermined value when the vapour discharge tube 66 is disconnected from the electronic ballast system 10. In this way the output voltage of the ballast system 10 is reduced essentially when the vapour discharge tube 66 is disconnected electrically from the circuit as a whole, which improves the reliability and prolongs the life of the vapour discharge tube 66. <IMAGE>
