Title: A method to safely restrain occupants in a crashing vehicle and a seat constructed to perform said method
Inventor: BLOMDELL PETER
IPC: B60R22/12
Filed: 1997-02-28
Abstract: The present invention relates to a method for a safe restrainment of occupants in a crashing vehicle using safety belts, and a double tube frame construction at the same time being a supporting body of the vehicle seat. The method is characterized in that in a crash the kinetic energy of the occupant is restrained by said belt and by the cooperating resiliently deformable double tube frame construction in such a way that, at a moderate load, the upper portion of this double tube frame construction will move resiliently, but with a bigger load a permanent deformation will be the result in said double tube frame construction at the same time as the resilient movability in a phase of permanent deformation also can cooperate in bringing the occupant back to the back rest of the seat by a resetting elasticity of the upper portion of the double tube frame construction.        The device is characterized in a seat frame with a seat portion and a back rest portion (B; A) being made of a parallell tube frame having two tubes (1, 2) arranged above/under and forward/behind, at the seat portion (B) and at the back rest portion (A) respectively, up to a height at the breast (D) of the occupant, and that the tubes are twisted above said height to a position side by side, and in reinforcing, deformable form plates (12) rigidly arranged between the parallel tubes (1, 2), at least at the seat portion (B) and at the lower portion of the back rest portion (A).

Title: Computer system and computer implemented process for representing software system descriptions and for generating executable computer programs and computer system configurations from software system descriptions
Inventor: MALONE THOMAS
IPC: G06F9/44
Filed: 1997-03-19
Abstract: A computer software system includes interdependent collections of software components. That is, at the architectural level, software components and their interdependencies are two distinct equally important entities. The software components represent the core functional pieces of an application and deal with concepts specific to an application domain. Interdependencies relate to concepts orthogonal to the problem domain in most applications, such as transportation, sharing of resources and synchronization constraints among components. An architectural description language which represents activities and dependencies between activities as separate entities. Dependencies are managed by coordination processes associated with the dependency. Activities and dependencies are connected through ports which encode interfaces between activities and coordination processes. The language may also represent resources which may be understood as the output of some activity beyond the scope of the system. Each entity, i.e., activity, dependency, port or resource, may also have attributes which are name value pairs, specifying additional information about the entity.  Attributes may be inherited. That is, activities and dependencies may be specialized into particular versions of an activity or dependency. The attributes for a particular activity are inherited by its specializations. An editor repository and design assistant may be based on this language to provide a system that automatically generates executable code.

Title: Apparatus and method for determining a parameter of a particle in a fluid
Inventor: DORAN CHRISTOPHER EUGENE
IPC: G01N15/06
Filed: 1997-04-11
Abstract: An apparatus and method for determining a parameter of a particle in a fluid is disclosed and, in particular, an apparatus and method for determining contamination or machine wear by the measurement of contamination or wear particles in a fluid used in the machine is disclosed. In a first embodiment, a measurement cell (10) is provided with a fluid flow path. A first hall probe (60) is arranged adjacent to the flow path for detecting dia-magnetic, para-magnetic, ferro-magnetic particles and a second optical sensor formed of a light emitting diode (50) and phototransistor (42) are provided for optically detecting the particles. A correlation between the hall probes (60) and the optical detector enables an indication of the particles to be obtained so that a parameter of those particles can be determined to provide an indication of contamination or machine wear. In a second embodiment, a measurement cell (10) having a fluid chamber is provided and two pulsed light sources are arranged in the cell for transmitting light through the fluid to a charged couple device (92) so that a first image can be produced by light transmitted through the fluid and therefore past the particles and a second pulsed light source is provided for reflection of particles so that a second image of reflected light can be produced. A comparison of the first and second images enables the metal particles to be determined so that parameters of those particles can be measured to provide an indication of contamination or machine wear.

Title: Clay/organic chemical compositions useful as additives to polymer, plastic and resin matrices to produce nanocomposites and nanocomposites containing such compositions
Inventor: KAIZERMAN JACOB
IPC: C09D7/43
Filed: 1998-12-08
Abstract: This invention is of a hybrid organoclay that consists of an organic chemical/phyllosilicate clay intercalate that has been ion-exchanged with quaternary ammonium compounds. Since this hybrid organoclay is hydrophobic, it can be washed in water to remove reaction salts and excess water soluble or water dispersible polymers to give a clean product via inexpensive means such as filtration. This allows a better dispersing composition to be prepared without the difficulties of isolation presented by prior art which uses energy intensive means to remove the bulk of the water from the final product and cannot be easily washed. In one aspect, the present invention provides a solid clay/chemical composition that comprises: (a) one or more smectite clays, (b) a quaternary ammonium compound which reacts via an ion exchange mechanism with the smectite clay, and (c) one or more non- anionic organic materials that intercalate with the clay. The invention is useful both as an ingredient to form nanocomposites and as a rheological additive.

Patent CA-2273271-A1 (CA)
Inventor: LANG DAVID J
IPC: F16H35/10
Filed: 1998-10-01
Abstract: A load limiter for preventing stall torque from being transmitted from a power drive unit to the flight control surfaces of an aircraft. The present invention provides such a load limiter in a package having lower weight and smaller spacial requirements than has been heretofore possible. The power drive unit of the aircraft generates torque which is transmitted from a rotating input shaft (24) to a worm gear (32), to a helical gear (38), to a ball screw, and to the flight control surface of the aircraft. If the flight control surface becomes jammed or otherwise prevented from movement, the ball screw, and consequently the helical gear (38), stop rotating. However, the stall torque of the power drive unit will continue to cause the input shaft (24) to rotate, which will in turn cause the worm gear (32) to rotate and interact with the helical gear (38). Since the helical gear (38) cannot move, the helical gear (38) will cause the worm gear (32) to axially translate relative to the input shaft (24). The worm gear (32) is normally prevented from such movement by compression and tension springs (58, 60) laterally flanking the worm gear (32), but by sizing the springs (58, 60) to be overcome by the level of the stall torque, one of the springs (58, 60) depending on the direction of rotation of the input shaft (24), will compress to allow the worm gear (32) to axially move and thus cause a toothed plate (44) attached to the worm gear (32) to engage a mating toothed plate (50, 52) fixed to the actuator housing. The engaged plates therefore ground the stall torque to the housing to prevent damage to the flight control surface and its transmission. The load limiter is disengaged by reversing the direction of rotation of the input shaft (24).

Title: Dynamic channel assignment method in a cell communication network
Inventor: VERRIER DAVID
IPC: H04W72/08
Filed: 1998-06-02
Abstract: The invention concerns a method whereby for each network base station each physical channel managed by the dynamic channel assignment (DCA) method is associated with a particular priority index computed on the basis of periodically measured radio parameters relative to communication intervening on this physical channel. For the assignment of a new communication channel, the free and accessible physical channels with the highest priority are given precedence. The priority indices can further be used for the dynamic transfer of current communications towards free and top priority channels, whereby the distribution of the pass band between cells as well the quality of communications is optimised.
