  • Publication number: 20210060509
    Abstract: A reforming reactor and process of using same in which a flow distributor distributes the process gas circumferentially to the reactive zone. Feed is injected into the reactor into a non-reactive zone. The non-reactive zone has two portions, a first portion receiving the feed, and a second portion receiving a purge gas. The purge gas will flow from the second portion to the first portion to prevent flow of the feed from the first portion to the second portion. The combined gas may be passed to a reaction zone for catalytic reforming. The first portion and the second portion may be separated by a flow distributor having two horizontal portions connected to opposite ends of a vertical portion.

  • Patent number: 10544613
    Abstract: This invention is about an improved garage door opener system, with design features for preventing garage door break-in from outside of the garage using an object such as a hanger. Typically, a person pulls down a cord connected to a release handle to release emergency release of a garage door opener, allowing the door to be manually open or closed. An unauthorized person may attempt to pull down the cord using a hanger from outside the garage or to pull or push down the release handle, to open the door from outside and gain unauthorized entrance. The improved garage door opener system provides a mechanism to reverse the pulling direction of the cord and also protects release handle from being accessed from outside the garage, for increased security.

  • Patent number: 10498367
    Abstract: A memory device may include memory components to store data. The memory device may also include a processor that may decode a codeword associated with the data. The processor may receive the codeword and determine whether the codeword is independently decodable using a BCH decoder. The processor may then decode the codeword using the BCH decoder when the codeword is determined to be independently decodable using the BCH decoder. Otherwise, the processor may decode the codeword using a second decoder and the BCH decoder when the codeword is not determined to be independently decodable using the BCH decoder.

  • Patent number: 10183956
    Abstract: The present invention relates to a water-soluble, simple, stable tris(N-(tert-butyl)acetamide) cyclen-based europium complex HGEu001 which exhibits the specific subcellular localization in the primary cilium with a quantum yield as high as 10% in water and a lifetime of 0.56 ms lifetime. In particular, the present invention provides simplicity of the design and synthesis of a complex. Comprehensive studies were performed in numerous cell lines, such as HeLa, SN-K-SH and MRC5; the motif structure, HGEu002, has also been synthesized as the negative control for in vitro imaging studies. The two photon in vitro imaging were done in three dimensions to emphasize on the specific localization in primary cilium of HGEu001. This is one of the very limited examples for direct primary cilium imaging.
