Title: Frequency modulated laser radar frequency modulated laser radar
IPC: G01S17/34
Filed: 1985-03-15
Abstract: An apparatus and a method for measuring the distance to an arbitrary target (52) includes a radiation source (62) producing a beam of coherent radiation the frequency of which is continuously varied. The beam is divided into a ranging beam and a reference beam. The'ranging beam is coupled to a ranging interferometer (70), which directs a portion of the ranging beam at the target (52). The ranging interferometer (70) produces a first signal indicative of the phase difference between a portion of the ranging beam directed at and scattered by the target and another portion of the ranging beam which has traveled over a path of fixed length. The reference beam is coupled to a reference interferometer (66). A portion of the reference beam is directed by the reference interferometer (66) along a reference path of a predetermined length X<sub>ref</sub>, and the phase difference between the portion of the reference beam directed along the reference path and another portion of the reference beam which has travelled over a path of a fixed length is measured. The phase difference between the two portions of the reference beam and the phase difference between the two portions of the ranging beam are processed to determine the distance of the target from the ranging interferometer (70). The number of fringes resulting from the wave interference produced in the ranging interferometer (70) and the number of fringes in the wave inferference pattern produced by the reference interferometer (66) are counted and used, together with the knownlength of the reference path, to determine the distance of the target from the ranging interferometer (70). Very accurate range measurements may be obtained provided that the frequency deviation of the frequency modulation and the signal-to-noise ratio of the system is adequate. The surface roughness of the surface may also be ascertained by determining reflectivity profile (i.e. the intensity of radiation scattered by the surface of the target for a plurality of different angles of incidence of the beam), and speckle pattern (i.e. modulations in the scattered radiation produced by interference between radiation scattered by different points of the surface). The measured reflectivity profile and/or speckle pattern parameters may be compared with experimentally-obtained data for preder- mined surfaces of known surface roughness in order to approximate the surface roughness of the target.

IPC: G21F9/28
Filed: 1985-09-04
Abstract: Apparatus and method for detecting radioactive compo­
nents in dry active waste. The apparatus comprises a means 
for reducing the waste to pieces of substantially uniform size 
and first and second radiation detecting means. Means are 
provided for conveying the pieces from the reducing means to 
the first and second radiation detecting means. Means are 
provided for dispersing the pieces of waste between the first 
and second detecting means so that the pieces which are col­
lected together in clusters can separate from each other to 
thereby increase the likelihood of detecting radiation emanat­
ing from the pieces.  
     The method comprises the steps of reducing the waste to 
pieces of substantially uniform size, examining the pieces for 
radiation emanating therefrom and then dispersing them and 
then examining them a second time for radiation.

Abstract: An adaptive mechanism is presented in the context of 
optimization of expert system applications. Both single 
and multiple processor implementations are disclosed. The 
mechanism is used to maintain a near-optimal sequence for 
scanning rule lists in expert systems. For a program 
containing a sequential-decision, chain with many independent 
or mutually exclusive outcomes with each decision having 
associated with it some fixed cost and probability, the 
adaptive mechanism tends to produce the optimal ordering 
automatically from repeated observations of the execution 
of the decision chain.

Title: Opticle collimating apparatus
IPC: G02B5/30
Filed: 1988-07-19
Abstract: An optical collimating apparatus employs a semi-­
reflective concave mirror (42) and cholesteric liquid 
crystal element (44). In one embodiment, the optical 
collimating apparatus is used as a heads-up display 
device. Images in the line of sight of an observer 
substantially pass through a transmitter/combiner (40), 
semi-reflective concave mirror (42), and cholesteric 
liquid crystal element (44) to an observer. Images 
generated by an image source (34) are focused on the 
transmitter/combiner (40) such that the 
transmitter/combiner (40) reflects the images into the 
line of sight of the observer. The generated images are 
transmitted by the primarily transmissive (convex) side 
of the semi-reflective concave mirror (42) to the 
cholesteric liquid crystal element (44). The 
cholesteric liquid crystal element (44) reflects the 
generated images back toward the primarily reflective 
(concave) side of the semi-reflective concave mirror 
(42), which in turn reflects the images back toward the 
cholesteric liquid crystal element (44), which transmits 
the generated images to the observer. In an alternative 
embodiment, such as in a flight simulator or similar 
device, an image source projects images upon the 
primarily transmissive (convex) side of a semi-­
reflective concave mirror which transmits the images to 
a cholesteric liquid crystal element. The images are 
reflected by the cholesteric liquid crystal element back 
toward the primarily reflective (concave) side of the 
semi-reflective concave mirror. The images are then 
reflected by the semi-reflective concave mirror back 
toward the cholesteric liquid crystal element which 
transmits the images to the observer.

Title: Process for the manufacture of dicarboxylic acids
IPC: B01J31/26
Filed: 1988-11-25
Abstract: An improved process for the manufacture of aromatic 
dicarboxylic acids and derivatives thereof is described. 
The process is based on the reaction of a corresponding 
aromatic hydrocarbon in a liquid phase oxidation with an 
oxygen-containing gas in the presence of a phase-transfer 
catalyst (a), a transition metal salt (b) and traces of a 
polar solvent, such as water, the molar ratio between (a) 
and (b) being in the range of between 0.25:1 to 1.5:1. 
The phase-transfer catalyst is selected from the 
quaternary ammonium and phosphonium salts having a total 
carbon atoms in the range of 17 to 58, the anion bound 
thereto being selected from Br⁻, F⁻, Cl⁻, OH⁻, CH₃COO⁻ 
and HSO₄. Among the aromatic dicarboxylic acids and 
derivatives thereof the following are mentioned: tere­
phthalic acid; isophthalic acid and methyl terephthalate. 
The process is characterized by the very high conversion 
of the respective aromatic hydrocarbon reaching even 
100%.
