Title: Flavor enhancement in cultured dairy products
Inventor: MEHNERT DAVID WEBB
IPC: A23C15/14
Filed: 1995-02-24
Abstract: Methods and compositions for flavor enhancement and development in a cultured dairy product employ identification and selection of fat fractions from sources such as milk(butter) fat for use as flavor precursors. The selected fractions are added to the product at a step in the manufacturing process where they are available for flavor development by means characteristic of the product. The selected fractions are preferably enhance for fatty acids and have low melting points. For a reduced fat product, the flavor precursors are generally added in combination with a fat substitute. Homogenization of all the aqueous protein component in this type of product was an improvement over homogenizing only a portion of this component. The invention is particularly suitable for production of reduced fat cultured dairy products.

Title: Method and apparatus for treating waste water streams
Inventor: MCBRAYER ROY N JR
IPC: B01J19/00
Filed: 1995-03-31
Abstract: A method for treating waste water streams by introducing a mixture of preheated waste water and an amount of oxidant lower than that required to oxidize all the organic matter in the waste stream into the front port of an elongate tubular reaction chamber. The amount of oxidant is high enough, however, to raise the temperature of the stream in the reaction chamber to 750-1,200 .degree.F. A first injection side port is located downstream from the front port of the reaction chamber at a distance at which the temperature has reached a maximum value, and 9-100 % of the available oxidant has been consumed. Oxidant and water are simultaneously injected through the first port, in a manner that the amount of oxidant is adequate to oxidize a specified amount of organic matter. and the amount of water is effective to counterbalance the heat produced by the reaction of the co-injected oxidant with the respective organic matter. At the point that 90-100 % of the newly injected oxidant has been consumed, a second port is used to introduce more oxidant and water in similar manner and under similar conditions. More ports are also used, following similar rules, until the organic matter has been substantially exhausted. The reaction chamber has a multiplicity of ports, so that depending on the particular stream. its BTU value. and other parameters. the appropriately spaced ports are selected as injection ports. Highly improved output is achieved by the process and apparatus of the present invention.

Title: Optical waveguide grating and production method therefor
Inventor: HIDAKA HIROSHI
IPC: G02B6/124
Filed: 1997-03-27
Abstract: An optical waveguide grating with radiative mode-coupling properties, with exceptional stability and reliability as an optical component, wherein the central wavelength of the rejection band has a low temperature dependence, due to the use of silica glass doped with germanium and boron for the core. The rejection bandwidth can be narrowed without increasing the grating length by forming the radiative mode-coupled optical waveguide grating in an optical waveguide wherein the mean relative refractive index difference of the core is greater than that of optical communication waveguides. The rejection can be increased by reducing the occurrence of cases wherein propagation modes of the core coupled to cladding modes once again couple to the core in planar optical waveguide gratings formed by making periodic changes in the waveguide structure along the direction of propagation of light in an optical waveguide having a cladding with a lower refractive index than the core surrounding the core, by making the thickness of the cladding at least thirteen times the thickness of the core.
