Title: Fluorescence scope system for dermatologic diagnosis
Inventor: LUI HARVEY
IPC: A61B10/00
Filed: 1996-12-04
Abstract: Apparatus for the diagnosis of a skin disease site by visual  fluorescence inspection comprising an excitation light source for illuminating the disease site,  a light guide for transmitting the excitation light directly to the disease site to generate fluorescence light and viewing goggles for processing the excitation light reflected and the fluorescence light emitted from the disease site to provide a fluorescence image of the disease site to a user. The fluorescence  image  is  used  to  aid  the  medical assessment  of  skin  conditions  and  the  diagnosis  of cutaneous diseases by supplementing the visual assessment of skin lesions made by the naked eye.  The apparatus can be used in several modes of operation that permit the viewing of full colour fluorescence images and enhanced two colour  images.     The  apparatus  can  also  use  image intensifying equipment to amplify fluorescence light so that even very weak fluorescing objects can be seen.   A method for acquiring and viewing the fluorescence images is also disclosed.

Filed: 1995-08-17
Abstract: A method for removing gaseous pollutants from a polluted flue gas stream of an oil or coal-fired combustion furnace. A source of liquified combustible gas and a combustible gas-fired furnace are provided. The polluted flue gas stream is passed through a dust removal apparatus and removes flue dust from the flue gas stream so as to provide a de-dusted flue gas stream. Heat is recovered from the flue gas to generate power therefrom. The de-dusted flue gas is compressed to a pressure of at least 10 psi gauge using the generated power to at least in part compress the de-dusted flue gas. The compressed flue gas and the combustible gas are passed through at least one multi-sided heat exchanger, where the compressed flue gas is first passed through one side thereof and the liquified combustible gas in an at least partially vaporized state is passed through another side thereof. The compressed flue gas is cooled sufficiently by the combustible gas that water and at least one gaseous pollutant of NO2, SO2 and CO2 are condensed and separated from the compressed flue gas to provide reduced pollutant flue gas. Fully vaporized combustible gas is passed to the combustible gas-fired furnace and combusted to a further flue gas and the further flue gas is passed into the polluted flue gas stream.

Abstract: A method of producing micron sized sulphur granules involving the following described steps.   Firstly, heating sulphur until the sulphur becomes molten.  Secondly, heating water and inducing movement of the heated water at velocity. Thirdly, injecting an unbroken stream of the molten sulphur under pressures in excess of 500 p.s.i. into the heated water moving at velocity.   An explosive dispersion of the molten sulphur into fine sulphur granules occurs, enhanced by shear forces exerted by the movement of the heated water at velocity. The described method is capable of producing spherical sulphur granules of less than 45 microns.  In the preferred ranges, spherical  sulphur granules of less than 10 microns can be obtained.

Title: Foundation construction system
Inventor: SPUDE GERALD T
IPC: E04B2/86
Filed: 1997-04-16
Abstract: A building system and apparatus for forming a wall. U-shaped channels and H-shaped or T-shaped members coupled at their sides by rigid links hold foam panels in a desired spaced relationship. Vertically oriented panels aligned and connected by T-shaped members or horizontally oriented panels stacked with and connected by H-shaped members are inserted into the U-shaped channels to form a structure of the desired length. Concrete is poured between the panels and members where it hardens to form a structural wall. The planar surfaces of the U-shaped, H-shaped and T-shaped members enable the members to be extruded, or roll formed, thereby substantially reducing member production costs. Furthermore, widely available conventional foam panels can be used, reducing panel production costs.

IPC: G01T1/20
Filed: 1997-08-01
Abstract: A scintillation detector (10) includes a scintillation crystal (14) and-a shock absorbing member (76) circumscribing the crystal (14).  A sleeve (98) circumscribes the shock absorbing member (76) which, in turn, is circumscribed by a housing (12).  The sleeve (98) provides for substantial controlled radial loading on the crystal (14).  A method of manufacturing the detector (10) includes placing the crystal (14) and shock absorbing member (76) into the sleeve (98), compressing the sleeve 98 and inserting the compressed sleeve (98) into the housing (12) such that the sleeve (98) substantially maintains its compression.  The radial stiffness causes vibration induced counts to occur at an excitation frequency which is above the operational bandwidth of the radiation measurements, thereby excluding vibration induced counts for radiation measurements.

Title: Method and arrangement for transformation of signals from a frequency to a time domain
Inventor: DEWAR KEVIN DOUGLAS
IPC: H04N19/625
Filed: 1993-06-25
Abstract: An IDCT method decimates a 2-D IDCT into two 1-D IDCT operations and then operates separately on the even and odd pixel input words.   In a common processing step, selected input values are passed directly to output adders and subtractors, while others are multiplied by constant, scaled cosine values. In a pre-common processing step, the lowest-order odd input word is pre-multiplied by ~2, and the odd input words are summed pairwise before processing in a common processing step.  In a post-common processing step, intermediate values corresponding to the processed odd  input  words   are  multiplied  by  predetermined coefficients  to  form  odd  resultant  values.    After calculation of the even and odd resultant values,  the high-order and low-order outputs are formed by simple subtraction/addition, respectively, of the odd resultant values from/with the even resultant values.   The input values are preferably scaled upward by a factor of ~2. Selected bits of some intermediate resulting data words are optionally adjusted by forcing these bits to either 1  or  0.      The IDCT system includes a pre-common processing circuit (PREC), a common processing circuit (CBLK), and a post-common processing circuit (POSTC), which perform the necessary operations in the respective steps.  The system also includes a controller (CNTL) to generate signals to control the loading of system latches and, preferably, to time-multiplex the application of the even and odd input words to latches in the pre-common circuit.
