  • Patent number: 10399261
    Abstract: The invention concerns a device and a method for producing a pipe lining in a pipe by introduction of a hardenable mass, wherein the mass is pumped through an outlet into an annular gap, which is formed by the pipe wall and the device arranged in the pipe. The device has a former, which is guided within the pipe in a predetermined spacing from the pipe wall along the pipe axis, so that the annular gap between the pipe wall and the former has a predetermined cross-section.

  • Patent number: 10258718
    Abstract: A process and apparatus for applying a needle lubricant to a syringe. The interface forces between the needle lubricant and the syringe at the tip of the needle are balanced by optimizing the flow rate of a positively pressurized gas that is delivered to the syringe. Such optimization prevents the formation of bubbles in the needle lubricant that is applied to the syringe, thereby providing a confluent, uniform and smooth lubricant coating on the exterior wall of the needle and prevents lubricant from contaminating inner portions of the syringe. The smooth and uniform lubricant coating may minimize dilation and glide forces and pain associated with the insertion of the needle into a patient's tissue. Additionally, a gas pulse may blow off the droplet of needle lubricant from the tip of the needle to further minimize dilation forces and associated patient pain.

  • Patent number: 8863685
    Abstract: A camera is used to take an image of an end surface of a honeycomb structure gripped by a hand. Based on the image, an initial rotation angle of the honeycomb structure around a vertical axis at a reference position where the image has been taken is recognized. An arm turning section is driven to convey the honeycomb structure gripped by the hand from the reference position to above a plugging mask. A rotation angle required to adjust the rotation angle of the honeycomb structure on the plugging mask to a desired final rotation angle is acquired based on the initial rotation angle recognized at the reference position and a rotation angle of the honeycomb structure around the vertical axis associated with the driving of the arm turning section from the reference position to above the plugging mask. The honeycomb structure is rotated based on the required rotation angle.

The containers are conveyed to an aspirating station to aspirate excess material while tilting the container toward the aspirating nozzle. Subsequent to the aspiration step, the containers are tilted in the opposite direction to distribute the material in the container. The material is then dried and the containers stacked and packaged. The coating material includes metal ions such as calcium or other divalent metal ions, in a suitable carrier that is able to bond the bottom inside surface of the container.

  • Patent number: 5632818
    Abstract: There is provided a liquid injection apparatus for use in a method of lining the internal surface of a pipe. The apparatus comprises a push car having a frame structure, a liquid tank for storing a necessary amount of liquid to be injected into the pipe, a liquid pump for pumping the necessary amount of liquid so as to inject the liquid into the pipe, and a liquid injection controlling device for controlling the pressure of the liquid being supplied through the liquid pump, for stopping the liquid injection after a predetermined amount of liquid has been injected into the pipe, and for stopping the liquid injection if the liquid pressure in the pipe changes beyond a predetermined range. The liquid tank, the liquid pump and the liquid injection controlling device are installed together in the push car so as to be easily movable.

  • Patent number: 5429706
    Abstract: A system for installing an elongated hollow handgrip over an elongated end portion of a golf club shaft is operable to apply a liquid adhesive to an interior surface portion of the hollow handgrip so as to produce a coating of adhesive thereon and then to apply the hollow handgrip with the adhesive coating applied on the interior surface portion thereof over the end portion of the golf club shaft. The liquid adhesive is applied by use of a probe capable of receiving the hollow handgrip over the probe. The probe has an elongated central passageway with an inlet for receiving a flow of liquid adhesive and an outlet for dispensing the liquid adhesive from the probe. Also, the probe has an annular groove in an exterior surface portion communicating with the passageway outlet for receiving liquid adhesive from the outlet and wiping the liquid adhesive onto the interior surface portion of the handgrip as it is being moved past the annular groove to removed from the handgrip from the probe.

  • Patent number: 5407026
    Abstract: Apparatus for installing grips on golf club shafts includes a grip lubricating device and a golf club shaft lubricating device. The grip lubricating device utilizes a wick which wipes against an inner surface of a grip. The wick is wettable by a lubricant that is held in a container. The golf club shaft lubricating device utilizes an absorbent, sponge-like liner that wipes against an outer surface of one end of a golf club shaft. Control valves regulate flow of lubricant from the container so that a controlled amount of lubricant is applied to the inner surface of the grip and to the outer surface of the one end of the golf club shaft.

  • Patent number: 5336523
    Abstract: A method of applying a liquid coating material to the inside of a tank(10) and performing a hydrostatic pressure test on the tank at the same time. The method is useable for applying a liquid vitreous enamel coating material to a water heater tank, to be subsequently dried and furnace heated to form a glazed enamel internal coating. Preferably the hydrostatic pressure test is performed by displacing coating material from a portion(68) of an accumulator(51) by pumping liquid into a flexible bladder(66) housed in the accumulator. Pressure from pump(76) is transmitted to the tank(10 by the liquid coating material and held for a prescribed time interval to prove tank integrity. The method avoids excessive shear, hence viscosity changes in thixotropic coating materials.

  • Patent number: 5230842
    Abstract: To rehabilitate an internally corroded underground pipeline, excavations are made at its opposite ends to which launching and receiving pipe structures are then secured. Various pig member sets, with appropriate treatment fluids carried thereby, are air-driven through the entire length of the pipeline to successively acid clean, etch, and neutralize its interior surface. The interior pipeline surface is then thoroughly dried by flowing dehydrated air through the pipeline. Specially designed leading and trailing extruder pigs, with 100% solid, high viscosity, solvent-free epoxy coating material therebetween, are then air-driven through the pipeline to extrude a first protective coating layer onto its interior surface. The first layer is then dried with dehydrated air.

  • Patent number: 5207292
    Abstract: A process for simultaneously lubricating the interior wall of a underground conduit, while by use of compressed air, placing in the conduit a cable along the entire length of the conduit. The cable is drawn through the conduit by a puller, or comparable device, which is connected to the head of the cable, and rests in the conduit in a substantially air tight relation. This puller transmits a traction force to draw the cable through the conduit. The internal surface of the conduit is lubricated substantially uniformly over the entire length as the puller travels along the conduit by means of a reservoir of lubricant of a variable volume. This reservoir is at the rear of the puller, but in front of the cable. The lubrication and placement of the cable is along the entire length of the conduit. The invention also concerns an apparatus for carrying this process.

    Abstract: A method and apparatus of applying a coating to a substrate is provided. A liquid resin is introduced into a first region at a predetermined pressure. The liquid resin is maintained within a first pressure range in the first region. Next, the flow of the resin from the first region to a second region is controlled so as to bring the resin from the first pressure range to a second pressure range, the pressures in the second pressure range being lower than the pressures in the first pressure range. The liquid resin is then applied at a pressure within the second pressure range to the substrate at a third region adjacent the second region.
