Title: Resilient fluid transporting network for use in absorbent articles
Inventor: THOMPSON HUGH ANSLEY
IPC: D04H13/00
Filed: 1995-04-28
Abstract: The present invention provides a resilient fluid transporting network suitable for use in absorbent articles. The fluid transport network includes a plurality of bicomponent capillary channel fibers capable of intra-fiber fluid transport. The fibers have a base portion and at least two walls extending from the base portion to form an external capillary channel. The walls and the base portion are made of a first polymeric material which has a first melting point temperature. The distal ends of the capillary channel walls are made of a second polymeric material which has a second melting point temperature lower than the first melting point temperature. When heat is applied to the bicomponent fibers at a temperature below the first melting point temperature and above the second melting point temperature the bicomponent fibers bond together at their distal ends to form an interconnected network of capillary channel fibers capable of inter-fiber fluid transfer between the capillary channels of the bonded capillary channel fibers.

Abstract: PCT No. PCT/EP96/01901 Sec. 371 Date May 2, 1997 Sec. 102(e) Date May 2, 1997 PCT Filed May 7, 1996 PCT Pub. No. WO96/35393 PCT Pub. Date Nov. 14, 1996A set for producing a jaw implant has an implant body (1) that may be screwed into the jaw bones and an implant head (3) that may be secured to the implant body (1) to receive a prosthesis or prosthesis-supporting structure. The lower insertion section of the implant body (1) is designed as an expanding body (7) with several expanding elements (7) that may be spread after the implant body is screwed into the jaw bones. The base designed as an expanding body (7) gives the implant body (1) a good support on the osseous substance of the supporting cortical layer. Since the implant bodies (1) finds in the expanding elements (8) a multiple support on the cortical layer of the jaw bone, the forces axially transmitted to the implant body during mastication are better absorbed, improving the durability of the implant. The load is not concentrated on a single point but is rather distributed over a larger area. In a preferred embodiment, the implant body is an elongated hollow body whose insertion bottom section is slotted several times in the longitudinal direction to form the expanding elements (8). A pin (2) is screwed into the hollow body for spreading the expanding elements. The implant head (3) is designed as a screwable cap which can be screwed on the free end of the pin (2).

Title: Process for continuously casting a thin strip as well as arrangement for carrying out the process.
Inventor: HOHENBICHLER GERALD
IPC: B22D11/16
Filed: 1999-03-24
Abstract: A process for continuously casting a thin metal strip controls has jets directed at casting rollers using sensor feedback. Sensor feedback can be taken directly from the rollers, or can be determined indirectly by sensing a condition of the thin metal strip. Surface conditions are controlled over a longitudinal extent of the rollers through locally controlled gas jets. The feedback control of the roller surfaces provides a more uniform casting surface and a more consistent output from the casting surface.

Granted: 2005-10-15
Abstract: In a process to admix a fluid into a fibrous suspension of e.g. cellulose, the fluid is esp. admixed at high relative speed and at a higher temperature of e.g. 180degreesC.  The admixed fluid is e.g. steam which heats the medium to e.g. 180degreesC. In a further embodiment, the admixed fluid is a reactive gas e.g. oxygen, ozone or chlorine. In a further alternative embodiment, the admixed fluid is e.g. water, peroxide, caustic solution, acid, additives, catalysts or other additive agents. The steam, gas or liquid may be admixed at high speed by themselves or in conjunction with each other. Also claimed is a commensurate assembly with e.g. a rotor (10) located between the incoming fluid and the fibrous suspension. A jet (16) distribution (15) array is located in the zone where high relative speeds pertain. The rotor has a hollow shaft (13) feeding the jets (16) with the incoming fluid. The rotor (10) assembly is located within a pipe bend or tank immediately prior to a reactor vessel.

Title: A method and apparatus for negotiating mobile services
Inventor: ALBERTSSON HENRIK
IPC: H04W4/00
Filed: 2002-11-21
Granted: 2005-08-24
Abstract: A method and apparatus for performing a service negotiation between a mobile terminal and a server offering mobile services. A service request is received from the mobile terminal including a list of requested services, which is compared with a set of available services that the server can provide. It is then determined which services that were requested but are not available and cannot be provided by the server. A delta list is finally transmitted to the mobile terminal comprising the services not available, such that the mobile terminal can determine which services that can be used. A pre-defined tree structure is preferably used for specifying services in the service request and delta lists such that a single root node specifies all services in nodes subordinated to the root node. In this way, the amount of exchanged information and processing in the mobile terminal are reduced.

Title: A system for and a method of controlling a vehicle drivetrain
Inventor: BELLINGER STEVEN M
IPC: B60W10/10
Filed: 2001-07-13
Granted: 2005-01-12
Abstract: A system for controlling a vehicle drive train comprises a stored engine characteristic map wherein a region of undesirable engine operation is defined. A control computer estimates the engine torque and compares said estimate with the actual measured engine torque. If the estimated engine torque is less than the actual measured engine torque the engine is allowed to operate anywhere in said characteristic map. If said estimated engine torque is greater than the said actual measured engine torque the engine is operated outside of said undesirable region or in a manner to limit operation in said undesirable region. Further disclosed are functions that may be utilised in computing said torque estimate, including, vehicle speed, rolling resistance, drivetrain drag force, road grade and current fuelling value.

Title: Locking apparatus including a cylinder lock and a mortise lock
Inventor: SOUTHALL IAN
IPC: E05B55/00
Filed: 2007-05-23
Granted: 2011-10-12
Abstract: A locking apparatus 1 for locking a slide-means operated lock device 2, comprises a cylinder lock 3 such as a key operated multipoint lock and a separate lever-type mortise lock 4. In the embodiment shown, the lever-type mortise lock 4 may be a five lever mortise lock or a three lever mortise lock. In the locked position, the mortise lock 4 disables the operation of the handle to open the door. Thus, if the cylinder lock 3 is tampered with as by key-bumping or any other means, operation of the handle does not allow the door to be opened as the bolt 11 of the mortise lock 4 is engaged in the slide bar 5b, i.e. is immovable, and so the bolts 6 remain in the locked position. Only on disengagement of the mortise lock can the slide bar 5 be operated.
