IPC: F16J3/04
Filed: 1990-03-08
Abstract: ABSTRACT OF THE DISCLOSURE            In general, it is difficult to mold properly sized automotive boots without flash to be removed from the top end thereof. In accordance with the present invention, such molding is achieved placing a tubular parison between a pair of mold halves, moving a blow pin assembly downwardly partly into the top end of the parison, closing the mold by moving the mold halves together, using fingers to stretch the open bottom end of the parison, moving a sizing mandrel into the bottom end of the parison, closing inserts on the bottom of the mold around the bottom end of the parison to size the latter, blowing the parison using air under pressure discharged from the blow pin, moving the blow pin assembly farther down into the parison to size and cut the top end of the parison, opening the inserts and removing the lower sizing mandrel, opening the mold, closing the stretching fingers, and removing the blow pin assembly from the boot, which is stripped from the mold.

Title: Apparatus and method for transient thermal infrared spectrometry

Abstract: - i -Apparatus and Method for Transient Thermal Infrared Spectrometry Abstract A method and apparatus for enabling analysis of a material (16, 42) by applying a cooling medium (20, 54) to cool a thin surface layer portion of the material and to transiently generate a temperature differential between the thin surface layer portion and the lower portion of the material sufficient to alter the thermal infrared emission spectrum of the material from the black-body thermal infrared emission spectrum of the material.  The altered thermal infrared emission spectrum of the material is detected by a spectrometer/detector (28, 50) while the altered thermal infrared emission spectrum is sufficiently free of self-absorption by the material of the emitted infrared radiation.  The detection is effected prior to the temperature differential propagating into the lower portion of the material to an extent such that the altered thermal infrared emission spectrum is no longer sufficiently free of self-absorption by the material of emitted infrared radiation, so that the detected altered thermal infrared emission spectrum is indicative of the characteristics relating to the molecular composition of the material.
