A method for the inspection of contained flowable materials within containers, such as detecting an explosive liquid in a luggage, and an apparatus for performing the method are described. The method includes the steps of: performing a radiation scan, using X-rays or Gamma rays, of a target item container of contained flowable material in a radiation scanning system to derive a spatially distributed and spectroscopically resolved measured dataset of the intensity of radiation emergent from the target item; considering the spatially distributed and spectroscopically resolved dataset of transmitted radiation intensity to be nominally determined in accordance with a relationship: [O].Math.[]=[] where the operators [] and [] define, respectively, physical parameters describing the liquid and the container and the system response and the operator [O] defines the relationships between the system response and the liquid and container parameters; numerically processing the measured dataset by operator inversion in order to derive a best fit solution of: []=[O].sup.1.Math.[]; and using that derived solution to determine the threat status of the target item.

SINGLE PIECE DROPLET GENERATION AND INJECTION DEVICE FOR SERIAL CRYSTALLOGRAPHY

A single-piece hybrid droplet generator and nozzle component for serial crystallography. The single-piece hybrid droplet generator component including an internally-formed droplet-generation channel, an internally-formed sample channel, a nozzle, and a pair of electrode chambers. The droplet-generation channel extends from a first fluid inlet opening to the nozzle. The sample channel extends from a second fluid inlet opening to the droplet-generation channel and joins the droplet-generation channel at a junction. The nozzle is configured to eject a stream of segmented aqueous droplets in a carrier fluid from the droplet-generation channel through a nozzle opening of the single-piece component. The pair of electrode chambers are positioned adjacent to the droplet-generation channel near the junction between the droplet-generation channel and the sample channel. The timing of sample droplets in the stream of fluid ejected through the nozzle is controlled by applying a triggering signal to electrodes positioned in the electrode chambers of the single-piece component.

20200271684 · 2020-08-27 ·

The weight of cellulose containing materials, including paper, cardboard, cotton fabrics and unprocessed wood will increase significantly when exposed to a novel form of energy, which the inventor has termed KELEA (kinetic energy limiting electrostatic attraction). This energy is comparable to what is commonly termed a universal life force in traditional Chinese medicine and what is also attributed to the beneficial health effects of certain naturally occurring and processed drinking water. These waters are sometime referred to as being energized, activated, micro-clustered, etc. The present invention describes a way to quantitatively assess the KELEA emitting activity of these beneficial waters, as well as other fluids, including gasoline and diesel fuels. The fluids can be monitored, even when contained in a sealed container, such as a mini-hot water bag.
