  • Patent number: 10877223
    Abstract: Aspects and techniques of the present disclosure relates generally to incorporating an index matching gel within a HMFOC such that as the HMFOC is mated, fiber tips protruding from multi-fiber ferrules of the HMFOC pass through the indexing matching gel to remove contaminates therefrom. The present disclosure also relates to a method of removing contaminates from optical fibers upon mating a hardened multi-fiber optical connector (HMFOC) with another HMFOC.
    Type: Grant
    Filed: August 25, 2017
    Date of Patent: December 29, 2020

  • Patent number: 10054137
    Abstract: A check seat assembly includes a check valve seat with a by-pass passage in parallel with a check valve passage of the check seat assembly to meter flow and maintain stability of a hydraulic system, such as a hydraulic cylinder. The check valve may include an o-ring seated in a V-shaped groove. The check seat assembly may allow flow from a pump to a hydraulic cylinder to freely pass through the check valve to pressurize one side of a piston of the hydraulic cylinder, such as a front side of the piston to retract a corresponding rod connected to the piston.

  • Patent number: 9207687
    Abstract: A relief valve includes a valve body having an inlet and an outlet; a passageway formed between the inlet and the outlet in the valve body; a valve tube positioned in the passageway having a generally cylindrical portion including a first outside diameter and a second generally cylindrical portion including a first inside diameter that is larger than the first outside diameter; a valve seat; and a spring positioned about at least a portion of the valve tube and biasing the valve tube away from the valve inlet to seal against the valve seat. The valve tube and valve seat prevent flow through the passageway when pressure at the inlet is below a predetermined pressure and wherein the valve tube moves axially away from the valve seat at the predetermined pressure allowing flow through the passageway from the inlet to the outlet.

  • Patent number: 9184979
    Abstract: Disclosed are various embodiments for facilitating communications between application components that are distributed among many devices across a network. This allows for the application to execute as if on one device even though the application components are on many devices. A component interface is generated for the application components. The component interface intercepts communications sent from an application component, locates the intended receiving application component, and generates a component interface packet with the location. The component interface packet is then put into a network stream. The receiving component listens to the stream to obtain component interface packets that indicate the location of the device running the receiving application component. The component interface decodes the component interface packets intended for components associated with the component interface and sends communications encoded in the packet to the application components.
