Title: Frozen carbonated beverage making device
Inventor: FRANK JIMMY I
IPC: A23L2/00
Filed: 1996-09-20
Abstract: An apparatus and method are provided for controlling a frozen carbonated beverage product made by mixing several ingredients (12) in a mixing chamber (18). The apparatus includes a process flow block (16) that controls the flow of the ingredients (12) from ingredient supply sources (24, 28) to the mixing chamber (18). A pair of transducers (144, 156) are provided for measuring the pressure of carbon dioxide and the pressure of the product in the mixing chamber. A pair of solenoids (157, 96) are provided which control the supply of the ingredients into the mixing chamber in response to command signals from a central processing unit (14). The central processing unit (14) instructs the solenoids (157, 96) to open so as to supply the mixing chamber (18) with ingredients when the pressure in the mixing chamber is low and to close ingredients to the mixing chamber (18) when the pressure in the mixing chamber (18) is high.

Title: Mobile node, mobile agent and network system
Inventor: SAWADA SUNAO
IPC: H04L29/06
Filed: 1998-05-11
Abstract: A mobile node moves from a first IP (Internet Protocol) network to a second IP network in a network system in which the first IP network capable of executing communication in accordance with both first and second kinds of IPs and the second IP network capable of executing communication in accordance with only the first kind of IP are connected with each other.  When the mobile node communicates a message with other nodes on the first network after its movement accordance with the second kind of IP, a header for the movement containing both home and foreign addresses of the first kind in IP is added to a header containing home and foreign addresses in the second kind of IP, and put to the message, is added.  The message to which the movement header is thus added is used for the communication between a first mobile agent on the first network and a second mobile agent on the second network, or between the mobile node and the first mobile agent.

Title: Coupeuse a papier a format variable
Inventor: WATHIEU PATRICK
IPC: B26D5/30
Filed: 1996-04-30
Abstract: L'invention porte sur un procédé ainsi que sur l'appareil correspondant permettant de couper, de manière sélective, des feuilles de papier (14) de longueur variable provenant d'un dispositif d'approvisionnement de papier comportant une bande continue de papier (12) se déplaçant d'un point amont vers un point aval, le long d'un parcours préétabli, en traversant deux rouleaux presseurs (16, 18), en direction d'une coupeuse rotative (58). Une unité de commande (80) agit sur la rotation de la coupeuse rotative (58). Un premier (101) et un second (87) capteurs analysent la position angulaire de la coupeuse rotative et des rouleaux presseurs, respectivement, et émettent des signaux d'entrée, représentatifs, respectivement, de celles-ci, à l'unité de commande. Un sélecteur de format (81) commandé par un opérateur envoie un troisième signal, représentatif de la vitesse et du format de coupe des feuilles individuelles (14) à partir de la bande, à l'unité de commande (80). Cette unité de commande réagit aux trois signaux de sorte que la coupeuse rotative coupe les feuilles à la longueur désirée et que les rouleaux presseurs amènent la bande à la vitesse souhaitée. Des capteurs optiques détectent l'emplacement de la fin de la bande ainsi que les emplacements de repères visuels (122, 124) sur celle-ci et envoient d'autres signaux d'entrée à l'unité de commande (809 de telle sorte qu'il est possible d'effectuer des coupes précises relativement à la position des repères visuels pour chaque feuille de papier coupée. Des corrections de la vitesse de la coupeuse rotative (58) sont faites de manière quasiment instantanée afin de compenser les variations de diamètre du rouleau presseur et de procéder à des modifications sur l'araignée de sortie afin de lancer un nouveau format de travail en réponse à un signal émis par une marque de reconnaissance optique (ORM) (124) sur la bande.

Title: Recycling process of a cross-linked polymeric material, in particular from electric cable coating materials
Inventor: TRIBOULET CARLO
IPC: B29C48/395
Filed: 1998-08-11
Abstract: A process for dereticulating a cross-linked polymeric material, such as cross-linked polyethylene from scraps of electric cable coatings or from unused cable coatings through a mechanical mixing cycle, wherein the cross-linked material is subjected to a specific power per mass unit such as to induce shear stresses in the material itself and temperatures higher than pre-established minimum levels. At the end of this cycle the material goes back to a thermoplastic state that may be substantially regarded as thermoplastic; then, following granulation, cooling, drying and sacking, the material will be ready for re-use, either alone or mixed with virgin polymers, according to usual operating technologies for thermoplastic materials.      Eventually, the mechanical mixing cycle may be preceeded by a preliminary crushing cycle of the cross-linked polymeric materials to be treated.  Preferably, the mixing cycle is carried out in a twin-screw extruder with special screw and temperature profiles.

Title: Low residue antiperspirant stick composition
Inventor: KASAT RADHAKRISHNA B
IPC: A61K/
Filed: 1997-03-18
Abstract: Disclosed are antiperspirant stick compositions that exhibit substantially no visible residue (whitening) upon application to the skin or after drying. The compositions include both emollients that are silicone materials and emollients that are not silicone materials, these materials having a refractive index of at least 1.4460, in addition to including a vehicle (for example, cyclomethicone), a gelling agent (for example, stearyl alcohol and hydrogenated castor oil) and the active antiperspirant material (for example, particulate antiperspirant metal salts). These compositions reduce the necessity of using expensive silicone materials, while still achieving antiperspirant compositions with substantially no visible residue.

Title: System and method for rapid shape digitizing and adaptive mesh generation
Inventor: MIGDAL ALEXANDER A
IPC: H04N13/239
Filed: 1997-03-20
Abstract: System and method for rapid collection of data points and construction of a computer model based on a multi-resolution mesh to describe the surface contours and color of an object (101). The system collects data by projecting shapes of light (121-125) against the object (101) and collecting (from a position of triangulation relative to the light projector) images of the light as it reflects from the object. The system and method are comprised of a multiple laser stripe generation process to project a number of light shapes against the object, the collection of one or more reflected laser stripes in a single image of an images collector (120) to gather sufficient information to reproduce points on the surface of the object. The system compresses the data associated with collected points, which allows for accurate values for the contours of the object to subpixel accuracy. A multi-resolution analysis, which maintains more points to resolve fine details and removes points to further smooth regions of the objects, leads to significant compression. The adaptive mesh, consisting of the connection of polygonal finite elements, is automatically generated by the system and is comprised to create multiresolution meshes at different tolerances.

Title: Reducing crosstalk between communications systems
Inventor: TERRY JOHN BRIAN
IPC: H04B3/06
Filed: 1997-01-15
Abstract: Modems (12, 14) using a telephone line (10) for high speed communications between them are arranged to monitor crosstalk (24, 26) from other existing communications systems (16, 18, 20, 22) with which they may mutually interfere, and adjust the power spectral densities (PSDs) of their transmitted signals to reduce overlap between the PSDs of the different systems, thereby reducing near end crosstalk. Communications can thereby be optimized for whatever crosstalk conditions may exist. The modems can have a master-slave relationship for communicating buffered frames in a half-duplex manner using a collision avoidance protocol for computer network access. Analysis of monitored crosstalk PSD information can be performed by each modem, by the master modem, or by a separate computer on the network. A digital signal processor used in each modem for receiving signals can be configured to be used at other times for the monitoring of crosstalk.
