  • Patent number: 11945111
    Abstract: A spatial parallel mechanism comprises a platform. Three or more legs configured for extending from a base or ground to the platform, each leg has a distal link, one or more distal joint providing one rotational degree of freedom (DOF) about a distal rotational axis, the distal joint connecting a distal end of the distal link to the platform. A proximal joint provides at least two rotational DOFs at the proximal end of the distal link. Assemblies of joints and links provide DOFs to each said leg between the proximal joint and the base or ground. The distal rotational axes of the three legs are parallel to one another.

  • Publication number: 20230118569
    Abstract: A tool configured for use to assemble and install trim into a steam conditioning valve. These configurations can include a device that mounts in place of a bonnet and an actuator that technicians remove from the valve. The device can cantilever the trim assembly, essentially providing a platform on which technicians can slide the trim assembly into the valve body (or out of the valve body) to complete install or repair of the device. As an added benefit, technicians can also use the device to assemble the trim in proximity to the subject valve.

  • Publication number: 20220057000
    Abstract: A locking mechanism is configured to secure a seat on a valve. The configurations may include a pin with a tapered end. The pin extends into the valve body to engage with an engagement feature, like a slot, on the seat. The slot may reside on the downstream side of the seat. This location can provide ready access to the pin, for example, through various feature found on the valve body, such as a boss. For steam conditioning valves, the locking mechanism may prove useful because it allows the seat to easily remove from the valve body.

  • Patent number: 10752936
    Abstract: A device for analyzing a biological sample which includes a separation and detection chamber into which an injection channel and a discharge channel open, a filter separating the chamber into two distinct spaces so as to define a first space into which the injection channel opens and a second space into which the discharge channel opens, the filter having a porosity suitable for the separation to be carried out, a rough bearing surface having a surface roughness parameter suitable for carrying out a mechanical lysis of the biological species present in the sample, the bearing surface being arranged in the first space, a flexible membrane arranged opposite the rough bearing surface relative to the filter and blocking an opening made through the housing.

  • Patent number: 9871748
    Abstract: A method has provides a router having an input, an output, and a shared memory. The router also has a forwarding path to forward a plurality of packets from the input to the output, and a service path to manage statistical data relating to packets forwarded through the forwarding path. The forwarding path has a counter to count aggregate packet information relating to the plurality of packets it forwards. Next, the method counts, using the counter(s), aggregate packet information relating to the packets forwarded through the forwarding path to produce count information. After producing the count information, the method uses the forwarding path to store the count information in the shared memory of the router, and then causes the service path to retrieve the count information from the shared memory. The service path ultimately produces statistical information using the count information retrieved from the shared memory.
