Abstract: The invention relates to a prefill syringe provided with a cylindrical cartridge into which a rubber stopper is inserted, and having a needle holder at one end and a collar at the other end thereof, the needle holder being capable of receiving a needle assembly comprising a cannula and a needle. A cap for protecting the needle holder is attached to the needle holder, leaving a gap between the needle holder and the cap whereby vapor or gas can enter into the cartridge during vapor or gas sterilization performed prior to filling the cartridge with a drug.      Alternatively, where a syringe needle is attached to the needle holder, a protector is attached in place of the cap to cover the needle. An elastic cylindrical member is externally engaged to span the needle holder and the cap (or the protector) so as to cover the gap provided between the needle holder and the cap (or protector) in order to seal the cartridge after it has been filled with the drug.      One or more ring-shaped projections which contact the outer peripheral surface of the needle holder and the outer peripheral surface of the cap are formed on the inner periphery of the elastic cylindrical member.

Abstract: Method of casting steel strip in which molten steel solidifies as a shell on a chilled casting surface (100). The casting surface (100) has a texture (101) formed by a regular pattern of surface projections (103) and depressions (102) and the steel chemistry is selected to generate in the casting pool deoxidation products which form on the casting surface (100) a layer of less than 5 microns thickness a major proportion of which is liquid during cooling of the steel to below its liquidus temperature in the formation of said solidified shell. The substantially liquid layer suppresses the formation of surface defects in the solidifying metal surface due to early deposition of solid oxides on the casting surface.

Title: Conversion system with electronic controller for utilization of gaseous fuels in spark ignition engines
Inventor: KLOPP GERHARD O
IPC: F02D37/02
Filed: 1997-08-25
Granted: 2001-12-18
Abstract: A  conversion  system  for  converting  a  spark ignition engine to operate on gaseous  fuel is disclosed. The  conversion  system  includes  an  electronic  controller which  operates  on  several  novel  principles  to  provide superior performance/responsiveness  and to  reduce exhaust emissions.  The controller in accordance with the invention assumes  complete  control  of  spark  ignition  timing  when gaseous fuel mode is enabled and generates independent spark ignition  signals  tailored  to  the  gaseous  fuel.    The controller  also  generates  an  independent  pulse  width modulated gaseous fuel injection signal that controls a high performance  electronic  solenoid  injector valve to  supply gaseous fuel to the engine.  Variable injector speed is used to compensate for the dynamic range of the engine.  A novel dual array block learn scheme is used to provide efficient fuel control in engines equipped with closed-loop monitoring systems and exhaust gas recirculation.   A gasoline power boost mode  is  also  provided to  enable  extra power when maximum engine torque is commanded.   The advantage is an efficient  fuelling  system  which  provides  all  of  the advantages  of  gaseous  fuels  while  preserving  the  power capabilities  of  liquid  fuels,   and  minimizing  exhaust emissions.

Abstract: L'invention porte sur un procédé continu de régulation générale de caisse de tête/formeur d'une machine à papier ou à carton ou analogue. Ledit procédé consiste à créer un modèle physique d'écoulement des fluides dans la caisse de tête/et le formeur relatif à l'égouttage et à l'état du courant de suspension de pâte, servant à réguler la caisse de tête (100) et le formeur (100'). Le modèle est résolu par intégration des données relatives à la géométrie de la caisse de tête (100) et du formeur (100') et des conditions initiales et limites. La différence entre l'état simulé provenant de la résolution dudit modèle et l'état pris comme cible donne une fonction de coût, l'état cible étant déterminé par les exigences de qualité du papier et éventuellement par des considérations de coût d'exploitation, et de possibilités de la machine. La fonction de coût ayant été optimisée, on recherche les valeurs optimes de réglage et de consigne (C) des instruments et des dispositifs de manoeuvre de la caisse de tête (100) et du formeur (100') correspondant à la fonction de coût donnée. Lorsque l'optimisation a eu lieu dans une étape précédente, les éléments régulateurs de la caisse de tête (100) et du formeur (100') reçoivent de nouvelles valeurs de réglage et de consigne (c).

Granted: 2002-04-09
Abstract: Disclosed is a telecommunication system (52-82) that is both highly cost effective for small scale applications (for example, those having less than 80 lines), yet field upgrade-expandable via a backplane bus (68) to applications having a significant number of additional lines (for example, 30,000 lines). An integrated voice/data telecommunication system is utilized that is flexible enough to handle low bandwidth (for example 64 kbps mu-law) speech as well as high bandwidth multimedia data switching. The system may be configured as a low cost, standalone PACS system for "village telephony" or "PACS-on-POTS" applications, as an alternative to requirements for PACS infrastructure when appropriate wireless network facilities are unavailable.

Abstract: Locking apparatus is mounted to a wall or inside a bag-supporting container. The fluid-storage bag has a tubular fitting with axially spaced flanges forming an annular locking area. The locking apparatus comprises a diaphragm mounted over a port formed in the wall. The diaphragm has a opening formed therein which has a size and polygonal profile which matches the polygonal perimeter of the fitting's locking area. Cuts extending radially from the vertices of the polygonal opening form radial flaps. The outermost flange is larger than the diaphragm opening and when forcibly pushed through the diaphragm opening it deflects the flaps. Once the outermost flange passes axially through the flaps, the flaps snap back flexibly and engage the fittings locking area, resisting fitting removal. The complementary polygonal tubular perimeter and diaphragm opening resist rotation aiding in installation of threaded accessories. A removable plug is provided for installation to port outside of the wall which, when installed, seals any fluid within the walled enclosure.

Title: Telecommunications network with portability of mobile subscriber number
Inventor: KILHAGE PER-ERIK MIKAEL
IPC: H04Q3/00

Granted: 2007-05-15
Abstract: A telecommunications network (10) comprises a set of service provider/operator domains (20), including mobile telecommunications domains (20A-20C). A call-originating domain (20F) accesses a mobile subscriber number portability database (30F) to obtain the address of the gateway node (GMSC) of the telecommunications domain which currently serves a called mobile subscriber having a mobile station (70), and optionally the address of the home location register (HLR) of the called mobile subscriber. The address of the gateway node obtained from the database (and optionally the address of the home location register) are included along with the directory number (MSISDN) or IMSI of the called mobile subscriber in a routing message for completing the call. When changing service providers (e.g., changing to a new domain), the mobile subscriber number portability database is updated to reflect the change. Access of the database and usage of the address of the gateway node of the new domain in the routing message permit the mobile subscriber to retain the same MSISDN when changing service providers.
