20090235692 | SAG CONTROL OF ISOPIPES USED IN MAKING SHEET GLASS BY THE FUSION PROCESS - Isopipes for use in making sheet glass by a fusion process are provided which exhibit reduced sag. The isopipes are composed of a zircon refractory which has a mean creep rate (MCR) at 1180° C. and 250 psi and a 95 percent confidence band (CB) for said mean creep rate such that the CB to MCR ratio is less than 0.5, the MCR and the CB both being determined using a power law model. The zircon refractory can contain titania (TiO | 09-24-2009 |

20110083792 | VELOUR CARPET WITH TUFTING-LIKE SURFACE - The present invention relates to a method for producing a velour rug, comprising the following steps: a) needling of a nonwoven/mali nonwoven on a bristle strip using a needling machine, in the process of which a pile nonwoven/carrier nonwoven is pulled into and partially back out of the bristle strip such that the fibers of the pile nonwoven/carrier nonwoven are located in the plane of the bristle strip, b) separating the nonwoven from the bristle strip by means of a roller brush, c) brushing the pile side prior to cutting the loops, characterized in that, in order to increase the fiber density and enhance the pile stability, an additional nonwoven/mali nonwoven, especially a pile nonwoven/carrier nonwoven, is placed onto the reverse of the nonwoven/mali nonwoven, especially between a first and second needling unit, between steps a) and b). | 04-14-2011 |

20130239827 | SYSTEM AND APPARATUS FOR MOUNTING HYDRAULIC CYLINDER TO PACKER PANEL OF REFUSE TRUCK - A refuse truck has a container for receiving refuse, and a packer panel for compacting refuse. The forces for compacting refuse are provided by hydraulic cylinders. The hydraulic cylinders extend through and are coupled to the packer panel. The hydraulic cylinders are telescopic or rod cylinders that have an open length several times their closed length. The hydraulic cylinders provide bi-directional forces so that the packer panel can be pushed away from or pulled towards the front wall of the container. | 09-19-2013 |

20110295043 | METHOD AND DEVICE FOR PRODUCING DIMETHYL ETHER FROM METHANOL - A process produces dimethyl ether (DME) from methanol (MeOH). The process includes charging a feed mixture consisting of raw MeOH and a process-internally obtained return flow substantially consisting of unconverted MeOH and reaction water to an MeOH column. The feed mixture is evaporated in the MeOH column to form a first distillate substantially consisting of vaporous MeOH. The first distillate is supplied to a reactor and the MeOH is converted to DME by splitting off water in the reactor so as to form a reaction mixture. The reaction mixture is withdrawn from the reactor, charged to a mixture column and separated into a bottom product substantially consisting of water and a second distillate substantially consisting of DME and MeOH. The second distillate is separated in a DME column into a third distillate substantially consisting of DME, a bottom product consisting essentially of water-poor MeOH, and uncondensable gases discharged overhead. The bottom product is either supplied to a top of the MeOH column or mixed with another bottom product withdrawn from a forerun column. | 12-01-2011 |
20120101312 | METHOD AND SYSTEM FOR PRODUCING METHANOL AND DIMETHYL ETHER - In the production of purified methanol and/or dimethyl ether from crude methanol, the crude methanol is processed in at least one prepurification stage, a first partial stream of the prepurified methanol is supplied to a final methanol purification and a second partial stream of the prepurified methanol is supplied to a reactor and at least partly converted to dimethyl ether. The dimethyl ether recovered is purified in at least one purification stage, wherein non-reacted methanol is withdrawn from the dimethyl ether purification stage and at least partly supplied to the final methanol purification. In this way, both purified methanol and dimethyl ether can be produced in parallel, wherein the quantities of both products obtained are flexibly adjustable. | 04-26-2012 |
