Abstract: Bearing support structure for turbines comprising an inner ring (1) and an outer ring (2) radially connected by means of structural hollows (5) and aerodynamic vanes (6) in a circumference-like arrangement between both rings (1, 2). The aerodynamic vanes (6) are thinner and lighter than the structural vanes (5), and the number of structural vanes (5) depends exclusively on the loads of the bearing (3) housed in the structure to be transmitted to the anchoring points (7) of the engine assembly located in the outer ring (2), and on the amount of service fluids which must go through between the inner ring (1) and the outer ring (2), while the number of aerodynamic vanes (6) and their section depends exclusively on the aerodynamic requirements demanded from the support structure for the straightening of the turbine main flow. Thus, the structural vanes (5) fulfill only structural functions and the aerodynamic vanes (6) fulfill only aerodynamic functions.

Abstract: Historically, content providers limit distribution of content to only those users having proper credentials to receive such content. Therefore, users typically had to enter credentials or use a device that has credential information thereon. Thus, a demand exists for verifying access to content and delivering the content to a user at a separate location from where credential information is provided. An item having a tag may be presented at a first location. A first device at the first location may acquire credential information from the tag. It may then be confirmed that said credential information meets requirements for receiving content. Further, a second device at a second location may be determined, and access to said content may be provided through the second device at the second location without requiring authentication information to be presented by a user at the second location.

Filed: 2010-02-24
Abstract: The invention relates to a device and to a method for taking over flexible, two-dimensional objects (100), in particular printed products, at a take-over location (SI). The objects (100) are received by receiver units (10, 12). According to the invention, controllable narrowing elements (20) are present, in order to prevent a squashing and rebounding of the objects (100) on or from an abutment of the receiver unit (10, 12), with which narrowing elements, in an active condition, the opening width (W2) of the receiver unit (10, 12) in a middle region between an entry opening (16) of the receiver unit (10, 12) and the abutment (15), may be reduced compared to an inactive condition. These are controlled with a control device (30). A  more reliable positioning of the objects (100) in the receiver unit (10, 12), in particular at high feed speeds and with thin, elastically deformable objects (100), may be achieved by way of the invention.

Abstract: The present invention provides a combination drape and carrying bag unit including a singular sheet or plurality of joined sheet of pliable materials, both permeable and impermeable, of size to define a mat to accommodate a working medical procedural area thereon, upon which may be placed in single or combination, medical equipment and patient. The sheet has a drawstring casing extending about its periphery.  The casing has openings therein on opposite sides of the mat and a drawstring is received in the drawstring casing and is of size to extend continuously about the periphery of the sheet when it defines a mat. The drawstring is slidably received in the drawstring casing so that when portions of the drawstring are pulled out of the drawstring casing through the openings, the periphery of the sheet forms gathers adjacent the casing to permit the periphery to reduce in size whereby the unit forms a carrying bag. Those portions of the drawstring which are pulled out of the casing may be secured together adjacent the openings to form a handle for the carrying bag.

Abstract: Methods and systems for abrasive cleaning, deburring pipes, providing barrier coatings and sealing leaks in existing pipes, in a single operation. A piping system can be cleaned in one pass set up by intermittent bursts of dry particulates that are forced and pulled by air throughout the piping system by a generator and a vacuum. Pipes can be protected from the effects of water corrosion, erosion corrosion and electrolysis, extending the life of piping systems such as copper, steel, lead, brass, cast iron piping and composite materials. Cleaning and barrier coating techniques described are efficient in pipes up to 2 inches in diameter, so that entire piping systems can be abrasive cleaned, coated and sealed. The leak sealant of approximately 4 mils thick can cover insides of pipes. Piping systems can be returned to service within approximately 24 to 96 hours.

Title: Separation of reactive cellulose from lignocellulosic biomass with high lignin content
Inventor: DOTTORI FRANK A
IPC: C08H8/00
Filed: 2010-04-23
Abstract: A process for separating the components of lignocellulosic biomass for the purpose of producing a pure reactive cellulose is disclosed.  The process has two stages. In the first stage, the lignocellulosic biomass is pretreated with steam, with or without an acid catalyst, and then pressed, with or without the presence of an eluent, to remove hemicellulose and other impurities. In the second stage, the pretreated biomass is extracted with a solvent such as ethanol with or without acid catalysts in order to remove lignin and release a purified cellulose stream. The extracted cellulose is then rapidly decompressed to rupture the fibrous structure. The process provides a purified cellulose stream that is relatively easy to hydrolyze with enzymes and ferment to biofuels and other chemicals such as ethanol.
