Title: Method of and an apparatus for producing a required visual signal for direct observation from a first source of light in the presence of a second source of light
Inventor: SHANKS IAN A
IPC: G09F9/00
Filed: 1989-10-06
Abstract: ABSTRACT OF THE DISCLOSURE      A required visual signal for direct observation is produced from a first source of light in the presence of a second source of light, such as ambient light.  Light is transmitted from the first source to a defined surface or defined region distant from the first source.  A means for modulating light is operated between at least a first mode and a second mode.  This operation is synchronised with a varying of the intensity of at least one of the sources of light at or above a given frequency equal to or greater than the critical fusion frequency for the size and luminance of the required visual signal.  When the modulating means is in the first mode, this allows the required visual signal to be directly observed on the defined surface or in the defined region.  When the modulating means is in the second mode, this allows the effect produced by any light from the second source incident on the defined surface or in the defined region to be reduced.
Patent CA-2001261-A1 (CA)
IPC: B41J2/525
Filed: 1989-10-23
Abstract: ABSTRACT OF THE DISCLOSURE         A  printed  image  (It4)  is  produced  with  halftone images for respective color printers while so-called rosette moire  and  a  color  shift  from  an  original  image  are prevented.  Halftone  dots  (Hm4,  Hc4,  Hk4) linear shapes extending in respective prescribed directions, thereby  forming  parallel  lines  with  respective  intervals (dm4, dc4, dk4).  These extensional directions and intervals of parallel lines are so established that they effectively prevent the rosette moire and the color shift.

Title: Metals assay apparatus and method
Inventor: SAYAMA YASUMASA
IPC: G01N23/223
Filed: 1990-05-15
Abstract: ABSTRACT OF THE DISCLOSURE      The present invention discloses an Fluorescence X-ray spectrometry method and device for determining the type and quantity of metals elements in metal and metal alloy samples, particularly precious metal and precious metal alloy samples. The invention provides a method and an apparatus in which an object to be analyzed is positioned so that an X-ray beam that will be generated will coincide with a measurement point on the surface of the object where it is desired that the analysis be carried out.  The measurement point is exposed to an X-ray beam having a diameter of 0.1 to 5 mm, causing fluorescence X-ray radiation to be generated which is sampled.  Spectral analysis of the captured fluorescence X-ray radiation is then carried out wherein the intensity of selected peaks corresponding to target elements is determined, whereby the relative composition of selected elements can be calculated, thus providing selective quantitative analysis for target elements at the measurement point.  The relative composition can be calculated by performing a computer analysis of the spectrum of the captured fluorescence X-ray radiation in which a fundamental parametric method is applied to the intensity values for peaks corresponding to each target element.
Patent CA-2019359-A1 (CA)
Inventor: MUTO HIROYASU
IPC: H04L7/04
Filed: 1990-06-20
Abstract: ABSTRACT OF THE DISCLOSURE:         A particular signal sequence corresponding in a received signal to a symbol pattern consisting of a predetermined number of symbols at a symbol interval, is detected by sampling (45-48) into phase samples substantially at the symbol interval of a phase of a signal vector obtained by coherent detection (11) of the received signal, calculation (51-52) of phase differences, each between two consecutive phase differences. detection (56-5?) of consecutive instances of coincidence of each phase difference substantially with a predetermined phase difference, and determination (58-60) of presence of the signal sequence in the received signal when the instances of coincidence substantially reach in number to the predetermined number,  Preferably, the sampling is carried out by making (11) I and Q signals represent the phase and converting (46-48) the I and Q signals to the phase samples by using a clock generator (45).  When produced (46-47), I and Q digital signals represent their amplitudes, which are subjected to conversion (48) into the phase samples.  The conversion, calculation, detection, and determination can be processed by a digital signal processor.

Title: Aromatic polyanhydride compositions
Inventor: DOMB ABRAHAM J
IPC: A61K9/70
Filed: 1990-08-08
Abstract: Aromatic anhydride copolymers containing at least two aromatic diacid units, which are soluble in chloroform or dichloromethane to concentrations between approximately 0.5 to 50% weight/volume, melt at temperatures below 180°C, and have low crystallinity are disclosed. The copolymers may contain between 0 and approximately 30% aliphatic diacid units. All copolymers are insoluble in carbon tetrachloride, i.e., less than 0.1% polymer by weight/volume solvent). The desired properties are the result of adding between 10 and 90% of a second aromatic diacid, to the copolymer composition which introduces irregularity in the polymer chains that dramatically alter the polymer properties, decreasing the crystallinity and melting point and increasing the solubility in the common solvents, dichloromethane or chloroform. An additional decrease in Tg and MP, with an increase in flexibility, is obtained by adding small amount of aliphatic diacid, up to about 30%.

Title: Method and apparatus for honing aircraft
Inventor: SPIRITO PETER P
IPC: B24B33/00
Filed: 1990-11-14
Abstract: Abstract An apparatus  for honing workpieces such as the midspans of jet aircraft engine blades is provided.  The apparatus includes a flexibly mounted honing stone which will seat itself on the flat surface of the workpiece to be treated.   To provide the necessary flexibility, the honing stone is mounted to a support in such a manner that it is pivotable about at least two axes.   It may also be moved  in  a direction which  is  substantially orthogonal to the two axes.   This latter feature allows the stone to move downwardly as the surface of the work piece is honed.   It also allows the honing stone to be moved entirely off the work piece and into a storage position.    The  apparatus  further  includes  a  support which is specifically designed for holding an aircraft blade in a position such that the wear surfaces of the midspans of such blades are in a substantially horizontal plane.    Two  clamping  assemblies  are  provided  for clamping the root and one of the midspans of a blade.
