Title: X-ray fluorescence imaging of elements
Inventor: WEBSTER JACKIE R
IPC: G01N23/207
Filed: 1990-10-09
Abstract: X-RAY FLUORESCENCE IMAGING OF ELEMENTS                        ABSTRACT A system for detecting the presence of known materials in a body or contain-er. The system incorporates a gamma or X-ray source for irradiating the body with gamma rays to produce X-ray fluorescence of materials contained therein. A direc-tionally discriminate X-ray detector is positioned to intercept X-rays emitted from the body and is adapted to pass only those X-rays having a predetermined wavelength and incident from a specific direction that are characteristic of a material of interest contained in the body. The detector includes a dislocation free single crystal having substantially parallel input and output surfaces. A second crystal aligned parallel to the first crystal may be disposed at a position offset from the first crystal to receive the X-rays transmitted by the first crystal in order to discriminate between materials fluorescing within the body. In a specific embodiment of the invention, the first de-tector comprises an elongated crystal which pass X-rays in accordance with the Bor-rmann effect. A plurality of the crystals are arranged in a linear array and the con-tainer is either scanned with the array or the container passed linearly past the array. The detected X-rays are measured in intensity and the data is processed by suitable data processor to generate a video image indicative of the presence and shape of the specific materials for which the system is adapted. In yet another specific embodi-ment of the invention, a plurality of such arrays can be arranged with the input sur-faces of the crystals disposed at different Bragg angles to simultaneously detect the presence of a selected group of materials.

Title: Flue gas desulfurization process
Inventor: MOSER ROBERT E
IPC: B01D53/50
Filed: 1990-12-18
Abstract: IMPROVED FLUE GAS DESULFURIZATION PROCESS              ABSTRACT OF THE DISCLOSURE      A wet, calcium-based, flue gas desulfurization process for reliably and cost effectively removing sulfur dioxide from the flue gas generated by the combustion of fossil fuels containing sulfur includes the  step  of  contacting  the  combustion  flue  gas preferably as a part of the scrubbing liquor, with an aqueous  solution  containing  formate  ions  and  a dissolved calcium concentration reduction agent.   The latter reduces the dissolved calcium concentration present in the flue gas which,  in turn,  reduces the coprecipitation and loss of formate within and from the system.   Also,  by contacting the  flue gas with an aqueous solution comprising formate and thiosulfate ions, the formate coprecipitation within the system is reduced independent of the calcium concentration level within the system.

Abstract: ABSTRACT The present invention involves an efficient process for separating selected components of a gas stream by integrating a cryogenic separation unit and a membrane separation unit. Two embodiments provide for the concurrent generation of an argon-rich stream in the gas or liquid phase, along with a nitrogen-rich product stream, both being produced from a stream normally comprising oxygen, nitrogen, and argon, e.g., air.      Broadly, the novel system uses a membrane means to preferentially reject the oxygen component from the recycle stream of the cryogenic unit, concurrently accumulating the argon component to allow its separation as an argon-enriched product stream.

Abstract: ANIMAL DROSS ABSORBENT AND METHOD                   ABSTRACT OF THE DISCLOSURE          A composition and method of absorbing animal dross.   In one embodiment,  the composition comprises discrete  particles  (about 50  microns  to  about  3350 microns,  preferably  about  600  microns  to about  3350 microns  in size)  of a water-swellable bentonite clay that effectively absorbs animal dross and simultaneously agglomerates into a sufficiently large and stable mass, thereby permitting physical separation of the soiled and weted  water-swellable  bentonite  clay  particles  from discrete particles of the unsoiled and unwetted water-swellable bentonite clay even after partial drying of about  1  to  24  hours  at  room  temperture,  without substantial sticking to animal paws and fur.  In another embodiment, the composition comprises discrete particles of a combination of water-swellable  sodium bentonite clay and calcium bentonite clay that effectively absorbs animal  dross  and  simultaneously  agglomerates  into  a water-dispersible but physically stable mass,  thereby permitting physical separtion of the soiled and wetted bentonite clay particles from discrete particles of the unsoiled and unwetted water-swellable bentonite clay, and  has  sufficient  water-dispersibility  for  disposal through a household plumbing or sewer conduit without clogging.  Beat results are achieved when the bentonite clay is non-compacted.

Abstract: A hardware device containing a first permanent key and a second key is plugged in a specified port of a computer to establish a communication path between the hardware device and computer.  The first and second keys are presented with an access sequence from the computer in the software which is desired to be controlled generating outputs which are applied to an algorithm decoder which provides a control key which is used to protect the software from unauthorized use.  The control key is the resultant of the algorithm decoder and the first and second keys.  One of the keys is supplied with the hardware under the control of the developer whereas the second key may be supplied with the hardware device but is not restricted to the hardware device and may be entered through a separate port of the computer.  The algorithm decoder can be included in any part of the software, the computer hardware or any combination thereof.  Many combinations of the first and second keys may be designed to produce the same control key when decoded.  One of the keys may be altered without regard to security, but there are certain values of the second key for each given value of the first key which will operate the software.  Providing a plurality of first and matching second keys which produce the plurality of different valid control keys allows the use of additional software that works in conjunction with the original distributed software acquired at a later date without the addition of additional hardware devices.
