    摘要: A vacuum debulking table for fiber reinforced thermoplastic prepreg includes a base, a base table mounted to the base, and a platen mounted to the base table. The platen has a frame and the base table includes a vacuum aperture located within the frame. A vacuum pump is connected to the vacuum aperture. The platen includes a heat generator. The table further includes tooling conforming to the frame and a kit to be debulked. A pair of opposing pressurized cylinders is coupled to the base at a first end. A top cover is mounted to the base and attached at a second end of the opposing pressurized cylinders. The top cover includes a flexible bladder. An insulator is mounted to the base table surrounding the platen. An insulation cover blanket is configured to be drawn between the insulator and top cover. An activation switch activates a programmable controller connected to the pressurized actuator control, the heat control and the vacuum control.

    摘要: An ionizing type smoke detector device has an output voltage which is compared with a reference voltage and upon the output dropping below the reference, a horn is energized. The reference voltage is normally quite low to reduce the number of false alarms and thus the smoke detector is relatively insensitive to smoldering fires which may require a high sensitivity of the smoke detector device. A timer means periodically modifies the reference voltage to a high value for a short period of time to make the smoke detector more responsive to smoldering fires and yet with the higher sensitivity for the short period of time the number of false alarms are kept at a minimum. Additionally a counter circuit is provided for counting the outputs of the smoke detector over three timing periods and if an output exists for three consecutive periods, an output to the horn is provided.

    摘要: A compression mold apparatus for compressing a segment has a base having an elongated and substantially semi-circular mold cavity and an end plate including a blade mounted thereon. The mold cavity has a top opening. A ram is aligned with the top opening. The ram includes two fixed opposing planar flank surfaces. The two fixed opposing planar flank surfaces are nominally centrally separated by a ram groove for mating with the blade while allowing linear movement within the mold cavity. A ram press is connected to the ram for translating the ram linearly along the blade within the mold cavity. A plurality of cartridge heaters is mounted in the base and arranged around the mold cavity for heating the segment.
