    摘要： An automatic cooling adjustment system for the forehearth of a glass furnace which enables the minimization of the amount of energy used in the forehearth. The system is utilized in a forehearth wherein a continually activated and adjustable cooling wind apparatus operates in conjunction with an electric or fuel fired heating system which controls or maintains the glass within a desired temperature range and at a predetermined temperature gradient range over the length of the forehearth. An automatic means is provided to adjust the amount of cooling wind and to maintain it at whatever level is required in order to minimize the opposing heating energy required. The system includes a timer which enables small automatic cooling wind adjustments during a first, relatively short time period and which enables temperature stabilization in the forehearth during a second, relatively long time period. The cycle of small adjustments is repeated as necessary to keep the heating system within pre-set energy limits.

    摘要： An integrated noise suppression acoustic panel includes a back plate, a face plate, and a bulk foam absorber disposed between the back plate and the face plate. The bulk foam absorber is formed of a thermoset material, such as bismaleimide or phenolic, and is manufactured using a low pressure process. In particular, a foamable material is melted, and a blowing agent is mixed with the foamable material to obtain a mixture. The foam is formed and the mixture is cured by heating it to a temperature, and maintaining the mixture at the temperature for a time sufficient to cure the mixture.

    摘要： A method of producing a multicomponent extrudate in which the operating line automatically and accurately extrudes the extrudate materials necessary to obtain the desired contribution of materials and specified dimensions of the multicomponent extrudate profile. The screw speed of each extruder can be adjusted to the desired speed by determining the actual thickness and width dimensions of the multicomponent extrudate. The actual measurements are then fed to a computer which calculates the corresponding values of the ratios of the extruder screw speeds to line speed. using the specified dimensions desired in the extrudate, the corresponding values for the screw and line speeds are also calculated. A comparison of the speeds based on measured dimensions, with the speeds based on specified dimensions, provides a measurement by which the screw speeds may then be adjusted such that the measurements of the extrudate profile are brought closer to the specified dimensions of the multicomponent extrudate profile.
