Patent EP-0156343-A3 (EP)
IPC: G06V10/70
Filed: 1985-03-25
Abstract: In a partial pattern matching system, a dictionary pattern, 
a pattern to be recognized and a binary-coding unit for giving 
a binary-coded image pattern by comparing each pixel with 
a predetermined voltage (10, 101 to 103) are provided. A 
polygonal approximation unit (104) gives a coordinate string 
of vertices of a polygon composed of a plurality of successive 
straight line segments approximately representing a contour 
of the binary-coded image pattern. A contour segmentation 
unit (106) judges a corner point among the vertex coordinates 
of the polygon based upon a criterion dependent upon the 
shape of the polygon. the corner point being used for dividing 
the polygon into a plurality of partial pattern. In a matching 
unit (107, 109), a correspondence pair is given by subjecting 
each combination of the partial patterns of the dictionary and 
recognition-object patterns to matching comparison, and 
each evaluation of matching degree is given for each of the 
correspondence pair.

IPC: A23F3/16
Filed: 1985-05-17
Abstract: The present invention comprises a liquid tea mix con­
centrate. The liquid tea mix concentrate is shelf-stable and 
substantially free of sulfur. It is characterized by a low pH, 
low water activity, high total solids, reduced levels of theaf­
lavin and thearubigin, and a polyphenolic profile and molec­
ular weight distribution distinct from other liquid tea mix 
concentrates. Tea beverage prepared from the concentrate 
is storage-stable in flavor and clarity. Acid-catalyzed degra­
dation reactions that normally occur between tea mix com­
ponents causing the development of off- flavor and 
malodorous sulfurous compounds and precipitates are ac­
celerated during processing. By removing the resultant com­
pounds, the development of off-flavors, off-aromas, and 
precipitates in the liquid tea concentrate is prevented without 
the use of preservatives.

IPC: H04N1/028
Filed: 1985-01-09
Abstract: Disclosed is a linear strip mask for controlling image plane 
light level distribution in line scan optical imaging systems. The 
mask is fabricated photographically on a strip of emulsion coated 
mylar. The photographic image which is recorded on the mylar 
strip is a pattern of alternating black and clear sections, the 
pattern of black sections chosen to modify the non-uniform light 
pattern output by the system's illumination source to obtain 
uniform image plane illumination.  
     Also disclosed is a line scan optical imaging system utilizing 
strip masks to compensate for the non-uniform light output along 
the length of two fluorescent tubes which illuminate the document 
scan line and the cos⁴ drop-off of the imaging system's lens. Light 
reflected off the document scan line is transmitted via a four 
bounce folded mirror system and is received by the lens system. 
Behind the lens system is positioned a multielement photoelectric 
sensor for converting light reflected from each unit area of the 
document line being scanned into electrical signals.

Title: Extinguishing device for an all-current power circuit breaker
IPC: H01H9/44
Filed: 1986-08-22
Abstract: The extinguishing device has ferro-magnetic extinguishing plates (2) in a housing chamber (1), located at a distance next to one another, which are provided in each case on their narrow side facing one contact point (3, 4) with a funnel-shaped V-slot (2a). Transversely in front of the extinguishing plates (2) there are arranged two dielectric material plates (5, 6) which make contact on the end face with tongues (2b, 2c) on both sides of the V-slot (2a) and flank the contact point (3, 4). The individual extinguishing plates (2) are provided with insulating, narrow arc tracks (8) in the centre region of their tongues (2b, 2c) from both outer longitudinal edges (2d) extending up to in each case the V-slot (2a), which arc tracks are designed as comb-like inserts (8) plugged in between the extinguishing plates (2). The lower dielectric material plate (5) covers a permanent magnet (9) and encroaches with a projection (5a) of its end face in front of a groove-shaped end contour (2a'') of the extinguishing plates (2). Above the permanent magnet (9), there is designed the insulating material plate (5) extending from the flat region (5d) flanking the contact point (3, 4) to the extinguishing plates (2) with step-like thickened regions increasing in steps (5b, 5c). The steps (5b, 5c) result in the switching arc (7) running into the V-slot (2a) well at DC currents above about 30 A. Subsequently, the comb-like inserts (8) prevent the partial arcs (7d, 7e) formed running back onto the tongues (2b, 2c) of the extinguishing plates (2) and keep them on the inner contours thereof. <IMAGE>

Title: Process for the simultaneous extraction of starch and proteins from wheat
IPC: C08B30/04
Filed: 1986-10-20
Abstract: The process for the separate extraction of all the principal constituents of flour from dry milled wheat products entails an aqueous suspension of milled products with a water/flour ratio of 1.0 - 3.0 being prepared and further reduced in size by a wet mechanical method, and the milled product suspension being adjusted to a temperature of 20 - 50 DEG C and subjected to a resting period of 5 - 120 min. The suspension of milled wheat product is subjected to a one-stage three-phase hydraulic classification in a centrifugal field to separate out the sediment containing the coarse grain starch, and the continuously produced centrifuge supernatant is fractionated by controlled phase separation in the centrifuge into a light phase containing the flour extractives and into a heavy phase containing flour gluten. The heavy liquid fraction with the partially agglomerated flour gluten is taken off above the centrifuge bowl and the light liquid fraction containing flour extractives is taken off at the upper edge of the centrifugal separating chamber. The processing of the intermediate products to the final products of coarse and fine grain starch, wet gluten and flour extract entails the material streams being passed countercurrently and thus the fresh water requirement being reduced to less than 2 m<3> per t of milled product, with an overall yield of up to 98 %.

Title: Fiber optic coupler and method
IPC: C03B37/025
Filed: 1986-08-11
Abstract: A low loss fiber optic coupler is fabricated by forming a coupler preform having a plurality of spaced glass cores extending longitudinally through a matrix of glass having a refractive index lower than that of the cores. The coupler preform is formed by inserting a plurality of coated optical fiber preform rods (26,27,28) into an aperture (20) extending axially through an elongated boule (21) of relatively etchable matrix glass. The cladding portion (35) of the rods, which is relatively etch-resistant, is coated with a layer of etchable glass (36). The coupler preform is heated and stretched to form a glass rod (43) which is then severed into a plurality of units (45; 49). Heat is applied to the central region (66) of each unit, and the central region is elongated and tapered inwardly. When an end of the unit is immersed in acid, the matrix glass dissolves, thereby leaving the unit cores and surrounding etch-resistant cladding glass protruding from the newly formed endface of the unit.
