  • Patent number: 11567054
    Abstract: A shaped lens for minimizing differences in time of arrival at the output surface of an explosive assembly. The lens is plano-convex with the convex shape oriented towards the explosive charge. The lens becomes monotonically thicker as the center of the lens is radially approached from the edge, according to a formula accounting for the detonation velocity of the explosive and velocity of the shockwave through the lens. The lens is preferably incorporated into a test fixture using a liquid explosive, such as nitromethane. The test fixture may be assembled on site, at the test location.

  • Patent number: 11536703
    Abstract: Pressure-controlled splitting can be used to inject a chemical sample from an injection source to a detector (e.g., a mass spectrometer) for chemical analysis (e.g., gas chromatography or gas chromatography-mass spectrometry) with reduced peak widths. For example, the sample is first transferred to a first compression volume; then pressure in the system is increased to compress the sample to split it between a second compression volume and a column. The fraction of the sample split to the column can have reduced peak widths compared to the peak widths prior to compression and splitting yet can maintain the same peak height to preserve high sensitivity for trace level analysis. This portion of the sample can traverse the column and elute to the detector for analysis with reduced chemical noise. Faster injection rates can allow faster analysis times, as less separation of chemicals is needed before the sample reaches the detector.

  • Patent number: 11513103
    Abstract: A portable gas analysis device having a separating column and a detector. The separating column is composed as a multi-capillary unit from parallel individual capillaries and, depending on the length, is bent into a compact shape, preferably even wound into multiple turns. A thermally conductive casing and a thermal stabilizing device are provided for the multi-capillary unit. The thermal stabilizing device comprises a temperature sensor, a heating element and control electronics. The casing protects the sensitive multi-capillary unit from mechanical actions; it acts as a protective space. The temperature-controlled casing also forms a space in which uniform and controlled conditions prevail and which in particular is isolated from the temperature and humidity of the environment, allowing reliable measurements outside a laboratory environment, in the field. This double effect of the casing for the capillaries in conjunction with the compact dimensions forms the true essence of the invention.
