Title: Method of transferring a sheet through a working apparatus
Inventor: HONDA NORIYUKI
IPC: B65H5/00
Filed: 2000-02-08
Granted: 2007-08-14
Abstract: According to a method of transferring a sheet through a working apparatus, a first sheet is moved by feed rolls partially into a working area of the working apparatus, which is followed by moving a second sheet by the same feed rolls to allow the leading end of the second sheet to be brought into abutment with the trailing end of its preceding first sheet and then to push the first sheet to a predetermined position within the working area.  After the first sheet is thus placed and the second sheet is moved back out of the working area, the apparatus is operated to work the first sheet, for example, by pressing. The second sheet is moved forward into abutment with the trailing end of the worked first sheet and moved further while pushing the first sheet toward delivery rolls of the apparatus, which then removes the first sheet out of the working area of the apparatus. Such steps of operation is repeated to transfer a series of sheets successively through the working apparatus.

Abstract: Corrosion in aqueous alkanolamine, physical solvents, or combination of alkanolamine and physical solvent solutions used to remove acid gases from natural gas, synthetic gas, or light hydrocarbon streams can be reduced by addition of mixtures of oxygen scavengers or mixtures of oxygen scavengers and sodium molybdate. The oxygen scavengers mu st be promoted to reduce metal surfaces in contact with the solutions to a more passive, harder, and insoluble form at the operating temperature of the treating system. The sodium molybdate provides additional passivation especially in the imperfections on the surfa ce of the metal where corrosion accelerates.

Title: Extruder head
Inventor: KAPPEN GUNTHER
IPC: B29C48/09
Filed: 2000-07-10
Granted: 2007-10-16
Abstract: An extruder head for extrusion blow-molding plastic containers includes a ring gap nozzle with a mandrel and a ring-shaped nozzle body. An elastically deformable sleeve is arranged on an end of the nozzle outlet side and defines a gap width which can be varied by axial setting movements of the mandrel and/or the nozzle body. The geometry of the nozzle gap can be influenced by radially deforming the sleeve with setting devices during the extrusion of a hose-shaped preformed blank. The sleeve may be moved in a radial direction and is guided on sliding surfaces which support it in upward and downward directions. The sleeve may be in the form of a cylinder or tube. A lower edge of the sleeve shapes a cross-section of a melt stream exiting from the ring gap nozzle.

Title: A method and system for providing interactive sms messaging
Inventor: ARMSTRONG CHRISTOPHER
IPC: H04W4/14
Filed: 2000-07-14
Granted: 2007-10-16
Abstract: The invention provides an interactive short messaging service (SMS) in which the short messaging service provider (SMP) stores short messages as content short messages (CSMs) which CSMs are then stored in a short messages menu (SMM). A user dials up the desired SMM, the SMP downloads the SMM and immediately terminates the call. The user now has a menu which may lead directly to CSMs which can be contacted directly or which can be a list of further SMMs. For example, the first SMM downloaded could be airline arrivals from one airport and on being downloaded could list all airlines servicing that airport each with a unique contact number i.e. a further SMM. The user clicks onto the desired airline from this SMM. A second CSM is downloaded in this case the times of arrivals of all that airline's flights that day. This may be sufficient for the user. The time taken for the two calls is minimal. The advantage is that it overcomes the problems inherent in present SMSs.

Abstract: A shipping and display case having a unique series of perforated tears and cuts for opening the case. The case may have a conventional box shape, including front, back, left, right, top and bottom panels, and the case is provided with a perforated tear line that is used to open the case. The score/tear line is formed by a multitude of perforations or slits; and the slits in selected portions of the tear line are substantially longer than the slits in the rest of the tear line. In particular, in the portions of the tear line that cross over left and right front edges of the case, and in selected angled portions of the tear line, the slits/cuts are substantially longer than the slits/cuts in the rest of the tear line. These longer slits/cuts make it easier to cut or tear line through areas where it is normally difficult to tear cleanly.
