  • Patent number: 11351701
    Abstract: The present invention proposes a method of industrial composite manufacturing. The method combines the resin transferring molding method with vacuum process and compression process in appropriate orders for achieving high quality products. In the curing process, microwaves are used to harden the plastic resin in the mold. Specifically, the main steps of the method are following: step 1: preparation of materials and equipment; Step 2: Disposition of the reinforced fibers/fabrics and mold closing at the extend position; Step 3: Vacuum and transfer plastic resin into the mold; Step 4: Mold closing by compression pressure; Step 5: Plastic resin curing by using a microwave system; Step 6: Open the mold and take the composite product.

  • Publication number: 20200376722
    Abstract: The air eliminator valve helps to eliminate air in the plastic resin used for composite products manufacturing. During operation, it continuously eliminates the air bubbles in the plastic resin running through the valve, and then transfers the filtered plastic resin into the mold. The design of the air eliminator valve consists of: inlet, inlet lock, air vent, upper cover, main body, ultrasonic generator, outlet lock and outlet. In which, the ultrasonic generator plays a role in generating ultrasonic waves to the plastic resin in the valve body that allows speeding up the air releasing process out the plastic resin. The air content in the valve could go out through the air vent on the upper cover, its status “open/close” is controlled by airlock with automatic response mechanism.

  • Publication number: 20070086352
    Abstract: The invention relates to a method of monitoring multimedia stream exchange session initialization messages transmitted in packet mode via a monitoring server over a network between a sender terminal and one or more receiver terminals. Said method comprises a step (50) of estimating a bit rate value for at least one initialization packet received by the monitoring server, a step (52) of comparing said value to a maximum authorized bit rate value, and a step (40) of authorizing transmission of the initialization packet only if the bit rate value for said packet does not exceed the maximum authorized bit rate value. The estimated bit rate value is optionally an average value that is measured over a sliding time window. The invention also relates to a server and an installation for carrying out the method of the invention.

  • Publication number: 20060174009
    Abstract: A method for establishing a multimedia session between a calling telecommunications equipment and a called equipment that is a mobile equipment of a network of the multimedia sub-domain type, wherein: an invitation (Invite) is sent from the first user equipment (UE1) to establish a multimedia session, which comprises as he destination address a public identity of the second equipment, said invitation being transmitted: by the first equipment (UE1) to a first proxy server (P-CSCF1), then, from this first proxy server, to a first session control server (S-CSCF1) of the network in which the first equipment (UE1) is registered, and from this first session server (S-CSCF1) to a point of entry server (I-CSCF2) of the network corresponding to the destination address of the second equipment (UE2); this point of entry server (I-CSCF2) interrogates a database (HSS2) of the network of the second equipment (UE2) in order to obtain the address of a session control server (S-CSF2) responsible for said second equipme
