Abstract: An example embodiment relates to preventing rotation of a barrel lock when opened by a key. At least one example embodiment includes a rotationally actuated barrel lock for securing electric meter boxes and the like, and a spring loaded clip for mounting inside the meter box. Lock actuation is characterized by rotation of a key relative to the lock. The barrel lock includes a head portion, and a smaller diameter shank portion with flatted areas thereon. The clip includes, in an example embodiment, a lock receiving opening with internal protrusions which engage the flatted areas on the lock shank, thereby preventing rotation of the lock when it is engaged by the key.

Abstract: This invention relates to a device for the determination of the sequence of nucleic acids and other polymeric or chain type molecules. Specifically, the device analyzes a sample prepared by incorporating fluorescent tags at the end of copies of varying lengths of the sample to be sequenced. The sample is then vaporized, charged and accelerated down an evacuated chamber. The individual molecules of the sample are accelerated to different velocities because of their different masses, which cause the molecules to be sorted by length as they travel down the evacuated chamber. Once sorted, the stream of molecules is illuminated causing the fluorescent tags to emit light that is picked up by a detector. The output of the detector is then processed by a computer to yield of the sequence of the sample under analysis. The present invention improves over the prior art by using photo-detection of the individual molecules instead of measuring the time of flight to a detector that measure collisions.
