Abstract:

A Drill Bit detector for use with numerically controlled drilling machine capable of sensing missing or broken Drill Bits in the range of 1 mil to 30 mils in diameter, or larger, is described. An infrared emitting diode is driven at a predetermined frequency with the pulsed light being directed through fiber optic cable directed at a portion of the Drill Bit to be detected. A change of light intensity occurring when a Drill Bit is missing is detected and the pulsed light detected converted to a pulsating electrical signal at the input frequency of the pulse light source. A frequency responsive circuit converts the pulsating electrical circuit to a digital signal indicative of the absence of the sensed Drill Bit. A timer determines whether or not the sensed digital signal occurs for a predetermined threshold time period, and causes it to be ignored as spurious if less than the predetermined time interval, or causes the drilling machine operation to be halted if occurring longer than the threshold time period. Multiple detection circuits are illustrated for use with most multiple drill spindles.

Abstract:

Presently described are polylactic acid polymer based films comprising a structured surface and articles. In one embodiment, the film comprises a semicrystalline polylactic acid polymer; a second polymer such as polyvinyl acetate polymer having a glass transition temperature (Tg) of at least 25 C.; and plasticizer. Articles are also described such as a tape or sheet, comprising the structured PLA-based film and a layer of (e.g. pressure sensitive) adhesive disposed on the film. In some embodiments, the tape or sheet further comprises a low adhesion backsize or a release liner. The article can be suitable for various end-uses. In one embodiment, the tape is a paint masking tape. In another embodiment, the tape is a floor marking tape.
