A temperature sensor is placed within a pipe or other underground structure to be rehabilitated and at least one temperature measurement is taken within the structure prior to or simultaneously with the installation of a liner. Once the temperature of an internal aspect of the structure is taken, a cure schedule is utilized to determine the appropriate curing time based on test data obtained from baseline tests performed under simulated conditions in a soil cell apparatus. A computer program may be utilized such that upon entering the type of resin, the lowest recorded temperature of the structure, and the initial resin temperature, a cure schedule is supplied.

    Abstract: A method and apparatus for moving along a tube extrusion line. An extruded tube is pushed through the extrusion line, by means of pressure generated by an extruder, to a withdrawal unit that takes over further driving of the tube. In a first-moving along phase, in which the tube has not yet passed a sealing of a calibration cooling unit relative to the atmosphere, the latter is under atmospheric pressure. In a second phase, in which the tube has passed the sealing, the calibration and cooling unit is placed under underpressure. In the first phase, the tube is supported either by internal overpressure or by a mechanical inner guide. A support cylinder extends axially from a casing head of the extruder and extends coaxially into a calibration sleeve in a first section of the calibration and cooling unit. A support plate is disposed between the casing head and an inlet of the calibration sleeve and provides external support for a tube exiting the casing head.

  • Publication number: 20120301566
    Abstract: The present invention relates to a foldable capsular vitreous body (FCVB), and its mould design, method for manufacturing, product appearance, and drug delivery property and so on. A mould for molding a foldable artificial vitreous body comprises an upper mould (1), a lower mould (2) and a core (3). The core (3) is disposed between the upper mould (1) and the lower mould (2) and is connected with a drainage-tube pin connected with an injection channel (4). Heating holes (6) are disposed in the upper mould (1) and/or the lower mould (2). Material is injected to the mould and is heated to vulcanize to mold vitreous body. The FCVB is adapted to be injected with any harmless medium and can be used as a delivery vehicle inside or around the eye ball. The size or shape of the FCVB can be changed depending on the different implant site.

  • Patent number: 8318061
    Abstract: In a mold temperature control circuit of an injection molding device, such a molding cycle is repeated that, prior to injection of a resin, a heating-use medium is returned to molds and heated to a temperature suitable for resin injection, after injection of the resin, the heating-use medium is switched to a cooling-use medium, thereby the cooling-use medium is returned to the molds and cooling is conducted to give a temperature equal to or lower than a temperature at which the resin is solidified.

  • Patent number: 8309010
    Abstract: A process for production of a heat-resistant hollow article made of a polylactic acid containing resin by using a mold which includes a female mold portion having a concavity, a male mold portion having a convexity and a stripper plate having an edge-forming part. The surface of the mold facing the cavity is heated to a temperature corresponding to a crystallization temperature of the polylactic acid containing resin. The male mold portion and the stripper plate are moved away from the female mold portion when a temperature T(° C.) of the resin detected by an infrared temperature sensor is in the range of T=(t+3.5)±1.5 (t(° C.) is the surface temperature of the mold). Gas is introduced between an inner surface of the hollow article and the male mold portion, and the hollow article is taken out of the mold by advancing the stripper plate toward the hollow article.

    Abstract: A closed loop blank mold temperature control system and method for use in the operation of an I.S. machine is disclosed for automatically adjusting machine timing to maintain desired blank mold temperature/heat extraction. The closed loop blank mold temperature control system uses measured blank mold temperatures to automatically control the supply of coolant air to the blank molds, which may be done independently to each blank mold half as well as independently to the plunger for each blank mold. The closed loop blank mold temperature control system can provide temperature setpoint commands, balance left and right parison temperatures, and maintain parison temperatures as a setpoint, all of which contribute to enhanced final glass container quality.
