Abstract: An eversion liner for lining a pipe includes an impermeable outer portion, inner and outer strength portions inside the impermeable outer portion, and a middle portion including at least one felt layer radially between the inner and outer strength portions. At least one of the inner and outer strength portions is formed from a unitary sheet of strength material that includes parallel chopped strands of fiber. The longitudinal edge margins of the sheet of strength material are positioned in overlapping engagement and joined together by joining structure. The parallel chopped fibers can be oriented transverse to the length of the liner. The joining structure can prevent reduction in a width of the overlapped edge margins as the liner expands during eversion.

Abstract: A microwave oven including a frozen food defrost mode and a food drying function according to the present invention includes: a body formed with a space therein; a humidity sensor measuring a humidity value of the space; a magnetron emitting microwaves towards the space; a power transformer supplying power for operating a heater of the magnetron; a high voltage transformer providing power for operating a resonator of the magnetron; a power supply unit supplying power to the power transformer and the high voltage transformer; an output adjusting unit for selecting and adjusting so that the magnetron outputs any one of a plurality of set output levels; and a control unit controlling an output of the microwave according to the output level selected in the output adjusting unit, blocking the power supplied to the magnetron when the humidity value input from the humidity sensor remarkably increases in short time.

Abstract: A cured in place liner system and associated connections and methods are disclosed. The cured in place pipe system forms a completely rehabilitated, stand-alone, fluid-tight flow path between upstream and downstream portions of an existing pipe system. The rehabilitated flow path is stand-alone in that the liner system does not rely on structure of the portion of the pipe system through which the liner system is installed to define the fluid-tight flow path. The flow path between upstream and downstream portions of the liner system is defined by and made fluid-tight solely by components of the rehabilitation system such as cured in place liners and couplers. The portion of the pipe system through which the rehabilitation system is installed merely provides a path (e.g., through the ground) through which the cured in place liner system can be inserted.

Abstract: A rehabilitated pipe system and a method for rehabilitating a pipe system. A lines a host pipe and a coupling member configured for being operatively coupled to a mechanical coupler is positioned adjacent the host pipe so that a connecting section of the liner extends into the coupling member. The connecting section of the liner is adhesively bonded to the coupling member, and the mechanical coupler is installed to fluidly couple the liner to another fluid conducting structure. The connecting section of the liner can be formed in a portion of the host pipe that is removed after lining. The coupling member can be flanged or include a lateral coupling tube. The mechanical coupler can, e.g., be a ductile iron coupler or a bolt.

Abstract: A liner for being cured by electromagnetic radiation having a wavelength in a curing range. The liner includes an outer portion. The outer portion includes a tube of impermeable material that is opaque to electromagnetic radiation having a wavelength in the curing range. An inner portion includes a tube of felt internally coated with an impermeable coating that is transparent to electromagnetic radiation having a wavelength in the curing range. The inner portion is inside the outer portion. A middle portion includes a tube of impregnable material between the inner and outer portions. Curable polymer that is curable by electromagnetic radiation having a wavelength in the curing range impregnates the felt and the impregnable material. Methods of manufacturing and installing the liner are also disclosed.

Abstract: A dried composition with various shapes that has heat resistance by which the dried composition is less likely to melt even being boiled and restorability (imbibition), and food product containing the dried composition. The dried composition including: agar and alginate at a weight ratio of 1:1 to 1:20, the alginate contains a salt of a monovalent cation and a salt of a divalent cation, the divalent cation is 0.04 to 0.30 mol per mol and further the monovalent cation is 0.10 to 0.70 mol per mol with respect to a monomeric unit of the alginate, a mol ratio of the divalent cation to the monovalent cation is 1.0:0.35 to 1.0:8.70, and the dried composition absorbs water and swells in distilled water at 20° C. and distilled water at 90° C., and in both the cases dried composition becomes a gel having a weight of 15 to 100 times of the dried composition.

Abstract: A liner tube for lining a pipe and pipe lining method. Liner material that includes a strength layer and felt backing layer forms the liner tube. The strength layer includes chopped strands of fiber oriented generally parallel to one another and distributed along the strength layer. The felt backing layer can be needle punched to the strength layer. Joining structure can connect opposite longitudinal edge margins of the liner material to form a tube shape. The liner tube is impregnated with a curable polymer, positioned in the pipe, and cured to form the liner. The liner stretches radially when it is positioned in the pipe. As the liner stretches, the strength layer remains fixed to the felt backing and the width of the overlapping edge margins does not decrease.

Abstract: An amount of radiation exposure of a medical staff is significantly reduced, and a large working area is ensured during an operation. A size of each component of a radiation protection equipment is reduced so as to decrease a weight thereof. The radiation protection equipment is provided, which can be installed within a short time period before an operation and easily put away after the operation. The radiation protection equipment, includes: a first protection sheet arranged on a periphery of a radiation source device and configured to shield radiation; a second protection sheet formed separately from the first protection sheet, arranged on a side of an operation table, and configured to shield radiation; and a third protection sheet formed separately from the first and second protection sheets, arranged on a periphery of a surgical field so as to expose the surgical field, and configured to shield the radiation.

Abstract: An air inversion and steam cure apparatus for installing a flexible resin impregnated cured in place liner in an existing conduit is provided. The apparatus has a low friction seal between a moving liner and the stationary apparatus gland. The gland is operated and adjusted by displaceable members that move substantially perpendicular to the liner being inverted to engage the moving liner as it passes through the gland. No part of the gland extends into the chamber so that once a pre-shaped gland is adjusted, the pressure on the moving liner is not increased. As the liner reaches the distal end, it enters a sample and porting pipe with an exhaust pipe gland and exhaust pipe and is pierced by a rigid porting tool. Steam is then introduced into the liner to cure the resin and is exhausted through an exhaust hose connected to the porting tool. After cure, steam is replaced with air to cool the liner and the ends are cut to restore service through the existing conduit.
