    摘要： A pipe assembly for a district heating network, comprising a first pipe, a second pipe and, surrounding the first pipe, a first insulating layer arranged to reduce heat transfer from the first pipe outwards in a radial direction, the first pipe being arranged for a first heat transfer medium flow and the second pipe being arranged for a second heat transfer medium flow. The pipe assembly comprises a heat transfer device arranged to transfer heat from an outer surface of the first insulating layer to the second pipe, and a second insulating layer arranged to reduce heat transfer from the heat transfer device and the second pipe outwards in the radial direction, the thermal conductivity of the heat transfer device being substantially better than the thermal conductivity of the first insulating layer and the thermal conductivity of the second insulating layer.

    摘要： A drawing device 4 is mounted in a drawing shaft 3, and pipe replacement device A connected with new pipes is arranged on the side of starting shaft 2, wherein the drawing device 4 and the pipe replacement device A is connected through pull-rods 5 inserted into existing pipes with each other. The pipe replacement device A is comprised of a cutting part 11 including cutter bodies 14 (shanks 14a to 14i) arranged in the axial direction and at angular intervals in the circumferential direction, an expanding part 12 having expanding rollers 18a to 18f, and a connecting part 13. Each cutter body 14 has a plurality of cutting edges, wherein distances between the respective cutting edges and the center of the circle become larger in order from the forward side toward the backward side. While the pipe replacement device A is traveled in the inside of cast iron pipes, the inner wall of cast iron pipes is cut by the cutter bodies 14 to form grooves. Splitting of existing pipes into arc-shaped pieces 1a is made starting from the grooves. Arc-shaped pieces 1a are pressed into the ground, by which a tunnel 7 surrounded by arc-shaped pieces 1a and portions of consolidated earth is formed, while new pipes 6 are introduced into the tunnel 7, and besides the new pipes 6 are protected by protective armors formed of arc-shaped pieces 1a.

    摘要： A tubing end-piece interconnects a free end of a piece of tubing and a tubing connector or fitting so that a fluid can flow between the tubing and the fitting or connector. The tubing end-piece includes a body member extending along a longitudinal axis with a bore extending longitudinally therethrough. The body member has an elongated body portion, a doughnut-shaped head portion and a frustoconically-shaped tail portion. The body portion has an outer body surface configured in a shape of a frustum that tapers from a first end and towards a second end. The doughnut-shaped head portion is connected to the first end of said body portion and extends radially outwardly relative to the longitudinal axis to form in cross-section an outer curved surface commencing from the first end and terminating in an outer peripheral edge which defines a first opening into the bore. A frustoconically-shaped tail portion is connected to the second end of the body portion and tapers from the second end and towards a second opening into the bore. The body member has an inner first surface and an inner second surface defining the bore and has a plurality of splines which are spaced apart from one another and extend longitudinally along and outwardly from the outer body surface. The present invention also includes a connector adapted to interconnect a pair of tubing end-pieces so that the fluid can flow between and through the respective pieces of tubing and the pair of tubing connectors, and present a connection which resists snagging when trailed from a portable or fixed source of oxygen gas to an ambulatory patient.

    摘要： A cordless telephone system includes a base unit connected to both a subscriber line and at least one branch telephone, and a mobile unit capable of being coupled to the base unit over a radio link. In the event that the handset of a branch telephone is switched on after a speech communication link has been established between the mobile unit and the subscriber line, an alarm may be provided to the user of the mobile unit. In addition, the user of the mobile unit may place the system in a holding state after a speech communication link has been established whereby the base unit and mobile unit maintain the speech communication link, but the mouthpiece of the mobile unit is disabled. In the event that the handset of a branch telephone is switched on, while the system is in a holding state, an alarm signal may be generated and output to a loud speaker at the mobile unit, and the mobile unit may be released from its holding state.
