  • Publication number: 20050126422
    Abstract: A bullet having a cavity in its forward end that is open at that end and a filling situated within said cavity. Preferably, the filling comprises an elastomer. Preferably, the elastomer filling is vulcanized. More preferably, the vulcanized elastomer filling has a Shore hardness in the range from about 6 to about 90. Alternatively, the filling is a colored rigid polymer filling, if a non-expanding training hollow point bullet is desired. In particular, the invention is a filling and its application to hollow point bullets for the purposes of: improving bullet expansion during the penetration of liquid targets; preventing clogging with debris from intermediate targets; increasing expansion during the perforation of hard materials; preventing the expansion of training bullets; and allowing users to identify different cartridge designs. The invention is also devices and methods for introducing the filling into the cavity.

  • Patent number: 6182372
    Abstract: A distance interpolator incorporated into a total station and a method for digitally interpolating a distance measurement from the total station to a target, such that the distance interpolator measures the distance from the total station to the target using primarily digital electronics and statistical analysis. In one embodiment, the total station transmits an energy pulse from the electronic distance measuring portion of the total station, with the energy pulse directed at the target. This embodiment then receives at the electronic distance measuring portion the energy pulse reflected from the target. This embodiment also contains a reference oscillator and digital counter, which counts the number of reference oscillator clock pulses that elapse from the time the energy pulse is transmitted to the time the reflection of the energy pulse is received.

  • Patent number: 5674387
    Abstract: The invention relates to a chiral selector useful in separating underivatized enantiomers of nonsteroidal anti-inflammatory agents, particularly naproxen and other arylacetic acid compounds, and relates to a process for achieving such separation utilizing the chiral selector, which is also useful in achieving the enantiomeric separation of amines, alcohol derivatives, epoxides and sulfoxides. The invention is also directed to an apparatus which comprises the chiral selectors.
