  • Patent number: 5818047
    Abstract: The presence of Semtex plastic explosive in a sample such as a fingerprint is detected by Raman spectroscopy. RDX and PETN, the active chemical ingredients of Semtex, have strong Raman peaks at 885 cm.sup.-1 and 874 cm.sup.-1 respectively. Consequently, both these peaks can be detected in a Raman spectroscopic system by employing a filter having a narrow passband centered on 880 cm.sup.-1 and with a bandwidth of 20 cm.sup.-1. Such a filter is used in a Raman system used to scan airport boarding cards, or in a Raman microscope which produces images of fingerprints.

  • Patent number: 4904010
    Abstract: A grasping tool for extracting the remaining portion of a broken torsion bar from a tracked vehicle has been devised. The tool (20) comprises at least one gripping jaw (24A) pivotedly mounted to a support shaft. The jaw (24A) is positioned opposite from an extension of the support shaft or alternatively a second gripping jaw, thereby defining a space therebetween. The movement of the engaging member (44) along a length of the support shaft into abutment against one end of the jaw (24A) causes an opposing end of the jaw to be urged toward the opposing extension or second gripping jaw and to retainingly engage an object positioned in the aforesaid space. The tool may have extension members and is constructed to be easily dismantled.

  • Patent number: 4183099
    Abstract: A knee protection device for use by athletes, particularly football players, consisting of a jointed rigid reinforcing bar adapted to be worn at the inside of the knee, with its pivot coaxial to the transverse axis of the knee joint, and extending above and below the joint, the surface of the bar next to the leg being specially conformed to the leg whereby to be firmly positioned when pressed firmly against the leg, a pair of straps encircling the leg and reinforcing bar respectively above and below the knee joint, and pressing the bar firmly against the leg, and an impact-operated strap tightening device interposed in each strap and operable to tighten the strap further whenever the knee receives a blow at its outer side.

  • Patent number: 4097932
    Abstract: A knee protection device for use by athletes, particularly football players, consisting of a tubular boot adapted to be worn on the leg at the knee, a jointed metal reinforcing bar mounted in the boot at the inner side of the knee, a pair of straps encircling the leg and reinforcing bar respectively above and below the knee joint, and an impact-operated strap tightening device operable to tighten each of the straps whenever the knee receives a blow at its outer side.
