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 welding method controls the welding temperature, welding cycle time, and welding pressure for fabrication of composite structural parts. A welding unit welds multiple plies of thermoplastic prepreg into welded multi-ply assemblies by concentrating welds along the thermoplastic prepreg plies at localized and strategic positions. Two platens weld a plurality of the multi-ply assemblies into a layup using a plurality of heated pins. The heated pins are hollow to reduce surface heating during welding and are non-uniformly shaped to allow indexing of the layup. After the layup is cut into a plurality of thermoplastic prepreg segments along a layup pattern, the thermoplastic prepreg segments are indexed according to the weld marks impressed by the non-uniformly shaped heated pins. The thermoplastic prepreg segments are formed into kits or wedges by stacking smaller thermoplastic prepreg segments on top of larger thermoplastic prepreg segments.
