Title: Metal dissolution with nitric acid
Inventor: DAVID CROSSLEY
IPC: C01G15/00
Filed: 2016-07-15
Abstract: A fast and efficient industrial scale process for producing metal nitrate solutions by metal dissolution using nitric acid which overcomes NO gas treatment requirements, by reacting the NO gaseous by-products with oxygen within the reaction vessel. This is done by provision of nitric acid in aqueous solution, provision of a metal in solid particulate form, which metal reduces the oxidation state of the nitrogen component of nitric acid from 4+ to 2+, such that nitric acid is converted to nitrous acid which then disproportionates to liberate NO and NO2, reaction of the metal with the nitric acid, the reaction medium having a headspace containing oxygen, where the metal particles are agitated by an impeller to provide directly or indirectly turbulent admixture of the nitric acid with the headspace containing oxygen, the headspace being maintained at a process pressure above atmospheric pressure, the headspace being replenished with gaseous oxygen to maintain a headspace oxygen concentration of 21% or greater by volume, the temperature of the reaction medium being maintained in the range 20 deg C to the boiling point of the nitric acid used at the process pressure. The method is particularly useful for copper, indium, silver and thallium nitrate production.

Title: Acquisition of a font portion using a compression mechanism
Inventor: Gregory A Kaplan
IPC: G06F17/21
Filed: 2016-12-22
Abstract: An end-user device determines multiple characters to be displayed but are missing from a local font. The end-user device computes a compressed representation of the multiple characters based on multiple code points corresponding to the multiple characters. The end-user device transmits a font request including the compressed representation to a font repository. The font request may be implemented as a uniform resource locator (URL), which may include a probabilistic data structure representative of the multiple characters. The font repository, such as a server, decodes the compressed representation to identify at least the multiple code points encoded by the end-user device. The font repository prepares a font description including glyph data corresponding to the multiple code points and returns the font description. The end-user device produces a local font that includes at least multiple glyphs corresponding to the multiple requested characters. The local font production may include font augmentation.

Title: Fluoro-alcohol additives for orientation control of block copolymers
Inventor: JOY CHENG
IPC: C09D7/65
Filed: 2016-02-08
Abstract: A film layer comprising a high-chi (ϰ) block copolymer for self-assembly and a hexafluoroalcohol-containing surface active polymer (SAP) was prepared on a substrate surface that was neutral wetting to the domains of the self-assembled block copolymer. The block copolymer comprises at least one polycarbonate block and at least one other block (e.g., a substituted or unsubstituted styrene-based block). The film layer, whose top surface has contact with an atmosphere, self-assembles to form a lamellar or cylindrical domain pattern having perpendicular orientation with respect to the underlying surface. Other morphologies (e.g., islands and holes of height 1.0Lo) were obtained with films lacking the SAP. The SAP is preferentially miscible with, and lowers the surface energy of, the domain comprising the polycarbonate block.

Title: Cellular telecommunications network
Inventor: Maria Cuevas Ramirez
IPC: H04W88/06
Filed: 2017-03-24
Abstract: A management node MME 50 in a cellular telecommunications network detects firstly the home network identifier of a user equipment UE 10 connected to the network and secondly the network operator identifier corresponding to the base station 20. If the identifiers are different, the UE must be roaming in a visited network. A preferred partner network of the UE home network is then determined (S16, fig 9) and a transfer of the UE to this network is initiated (S17, fig 9). The UE is a multi-subscriber UE with a second connection to a second base station 30 related to a second subscription, and the home network of the second connection may be different from that of the first. The MME may determine the home network of the first UE connection using the IMSI of its first SIM card, which identifies the corresponding Public Land Mobile Network (PLMN). Similarly, the PLMN of the base station may be identified from its ECGI. In a second embodiment, a handover is performed based on the resource usage of a UE.
