  • Patent number: 11512806
    Abstract: A restraint system for use in securing temporary flow lines that include multiple pipe sections, each pair of pipe sections connected together with a fitting or coupling such as a hammer joint coupling. The system includes multiple pluralities of endless loop slings connected end to end with a cow hitch or girth hitch knot. Disconnectable fittings (e.g., shackles) are placed every three or more slings so that easy disassembly is afforded in case of leakage or other failure. In one embodiment, a waterproof sleeve is an outer layer that surrounds or encapsulates an inner layer so that the inner layer remains dry and thus will not freeze.

  • Patent number: 9332563
    Abstract: A wireless communication includes: a communication unit; a storage unit; a transmission buffer; and a controller. The communication unit wirelessly communicates with a reception terminal. The storage unit stores information relating to a timing at which the reception terminal changes from a first state to a second state. The first state is a state of being able to receive data and continues for a first period. The second state is a state of being unable to receive data and continues for a second period. The first period is extended by a fixed duration when the reception terminal in the first state receives data. The transmission buffer temporarily stores segmented data constituting transmission data to be transmitted to the reception terminal. The controller controls the communication unit to wirelessly transmit dummy data to the reception terminal by the timing if the segmented data is not stored in the storage unit.

  • Patent number: 5885450
    Abstract: A water purifier includes a quick connect connector in a port that receives a tube that carries the water. The tube is received along the axis of the port in a first reference direction along the axis. The connector is assembled by inserting, in sequence, a support ring, an O-ring, and a plug into the port along the axis, but in a direction opposite the first direction. The plug is held in place by adhesive or conventional welding. To complete the assembly, a collet is inserted into the port along the axis and in the first direction. A tube is then connected to the water purifier by urging the tube through the collet, along the axis, and in the first direction. The tube is gripped by the collet, supported by the support ring, sealed by the O-ring, and stopped against the plug.

  • Patent number: 5825519
    Abstract: An optical demultiplexer includes a first optical path that includes a first nonlinear optical element (NLE) which responds to a control pulse to induce a 180.degree. phase shift in an optical data signal propagating therethrough. The NLE responds rapidly to the control pulse but slowly reverts to a non-phase shift state. A second optical path is provided which includes a second NLE. An optical output coupler is connected to the first and second optical paths and responds to in-phase data pulses therefrom to output a data pulse on a first output. The optical output coupler is responsive to 180.degree. phase shifted data pulses to output a corresponding data pulse on a second output. An input data source concurrently couples a train of optical data pulses of wavelength .lambda. onto the first optical path and the second optical path. A control input induces a first control pulse of wavelength .lambda. onto the first optical path and a second control pulse of wavelength .lambda.

  • Patent number: 5472215
    Abstract: A seal for communicating high vacuum onto rotating machinery such as a ceifuge. The seal comprises an outer pipe defining a volume to be evacuated, an inner pipe connected on one end to a vacuum source with the other end disposed within an end of the outer pipe such that an annular space is defined between the inner pipe and the outer pipe. Fluid is disposed in at least a portion of the annular space. The fluid is also disposed in a reservoir provided with cooling coils which lower the temperature of the fluid and thereby lower the vapor pressure of the fluid. The lower the vapor pressure of the fluid, the higher the level of vacuum which can be produced and transmitted.

  • Patent number: 4449738
    Abstract: A rotary fluid coupling for conveying fluid from a stationary shaft to a hub rotatably mounted on the shaft, or vice versa. The coupling is characterized in having a shaft provided with an axial passageway extending therethrough, one end of the passageway being connected to a source of high pressure fluid and the other being connected to a source of high-viscosity sealing fluid (e.g., a lubricant). A piston in the passageway separates the high-viscosity sealing fluid from the high pressure fluid, the latter being conveyed to the surrounding hub through radial passageways formed in an enlarged diameter portion of the shaft. The high-viscosity sealing fluid is applied to both ends of the enlarged diameter portion of the shaft to form a seal which prevents escape of the high pressure fluid.
