| 20100076227 | FLUIDIZED CATALYTIC PROCESS FOR PRODUCTION OF DIMETHYL ETHER FROM METHANOL - The present invention provides a fluidized catalytic process for production of dimethyl ether from methanol, wherein said process is carried out in a reactor in which the catalyst is in a fluidized state. Said process comprises the following steps of (1) feeding the methanol feedstock via two or more locations selected from the bottom, lower part, middle part and upper part of the reactor, contacting with the catalyst for preparation of dimethyl ether by methanol dehydration, carrying out the reaction of preparing dimethyl ether by methanol dehydration to obtain the reaction stream, separating said reaction stream to obtain a coked catalyst and a crude product primarily containing the target product, i.e. dimethyl ether; (2) totally or partially feeding the coked catalyst obtained in step (1) into a regenerator in a continuous or batch manner for regeneration via coke-burning, the regenerated catalyst being directly recycled to step (1) after being totally or partially cooled. | 03-25-2010 |

| 20110138841 | ICE DISPENSER FOR A REFRIGERATION DEVICE - An ice dispenser for a refrigerator is provided. The ice dispenser includes an ice storage container housing and an ice generator having a hollow mold which is filled with water. The ice storage container housing and the ice generator are combined into one modular unit. | 06-16-2011 |
| 20110138843 | REFRIGERATION DEVICE HAVING AN ICE-CUBE MAKER - A refrigerator having an ice-cube maker is provided. The refrigerator includes a collection container to collect the pieces of ice produced by the ice-cube maker. The collection container has a panel and is removable from the refrigerator. The refrigerator further includes an ice-cube production apparatus associated with the collection container and a cover which blocks access, at a front side, to the ice-cube production apparatus. The cover is rearwardly offset in relation to the panel of the collection container. | 06-16-2011 |
| 20110139817 | DISPENSER NICHE FOR A REFRIGERATOR - A dispenser niche for a refrigerator is provided. The dispenser niche includes an illuminator to at least partially illuminate the niche. The illuminator has LEDs that are arranged on a common circuit board with first electrical contacts. A wall of the dispenser niche has second electrical contacts and a recess that receives the common circuit board in a single orientation. The first electrical contacts of the common circuit board and the second electrical circuits of the wall touch each other in the single orientation. | 06-16-2011 |
