Title: A co-crystallization method adopted to boost the erythritol sweetness and product thus obtained
Inventor: WANG TINGGANG
IPC: A23L33/00
Filed: 2012-06-21
Abstract: The present invention relates to a co-crystallization method adopted to boost the erythritol sweetness and the erythritol cocrystalline thus obtained. The invention consists of the following procedures: (1) Prepare the supersaturated erythritol solution;  (2) Add the high sweetener to the supersaturated erythritol solution; (3) Co-crystallize the erythritol: continue to cool the supersaturated erythritol solution mixed with the high sweetener and thus obtain the co-crystalline product of the erythritol and the high sweetener; (4) Co-crystallized erythritol is dried by the heat of crystallization in the crystallization process and under normal circumstances requires no further drying. If necessary, the product may be dried in the range of 40-60 . The erythritol cocrystalline of different sizes may be obtained by sieving. The present invention takes advantage of the excellent crystallinity of the erythritol and binds the high sweetener and the erythritol together through co-crystallization. The invention improves the sweetness of the erythritol and featuers stable sweetness, uniform content and simple process.

Title: Thermally compensated arrayed waveguide grating assemblies
Inventor: MCGINNIS BRIAN P
IPC: G02B6/12
Filed: 2012-05-31
Abstract: Arrayed waveguide grating can have one or both slab waveguides with relatively sharply folded optical paths and a mirror that provides the folding of the path. The folded optical paths through the slab waveguides can result in a more compact geometry of the waveguides through the device as well as smaller slab waveguides such that the device can be formed with a significantly smaller overall footprint. Also, arrayed waveguide gratings that cooperate with pivotable mirrors can adjust light passage through the waveguide in response to temperature changes to provide for thermally compensated operation of the device. Thus, very compact planar lightwave circuits filters are described that provide thermally compensated operation.
