Title: Raster operations
IPC: G06T1/20
Filed: 1989-03-22
Abstract: A system and method for performing raster operations 
in a patch access environment utilizes two or more source 
patches to produce an XY shifted destination patch. Even 
though the present invention operates in a patch access 
environment, it can form a destination patch by merging 
groups of pixels not residing within the same patch 
boundries. The shifting and merging used to form the XY 
shifted destination patch can be done on a patch plane basis 
or on a patch basis. The X shifting and merging effectively 
combines preselected contiguous columns of contigous 
patches. The X shifted patches are then shifted in the Y 
direction to produce XY shifted patches. A line of the XY 
shifted patches is stored in a memory. A second, contiguous 
line of XY shifted patches is also stored in the memory. The 
stored lines of XY shifted patches are merged and merged XY 
shiftedpatches can be read out of the memory in a page 
mode fashion. Boolean or arithmetic operations can be 
performed between the merged XY shifted patch and 
preexisting data within a destination patch area so as to 
produce the XY shifted destination patch.

Title: Multiplexed fibre optic system with auxiliary channel
IPC: H04L7/02
Filed: 1989-11-01
Abstract: A digital data transmission system wherein 
digital data channels are serially multiplexed and in 
which channel identification is encoded by displacements 
of zero crossings of the multiplexed data. The 
multiplexed data stream is differentially encoded so 
that data bits of one significance are represented by 
the presence of transitions in the transmitted signal at 
predetermined times and data bits of another 
significance are represented by the absence of 
transitions at said predetermined times. The 
differentially encoded signals are added to a clock at 
half the interleaved bit frequency so that the rising 
and falling edges of the bits are advanced and retarded 
according to their bit position. The multiplexed data 
with added clock is then high-pass filtered and linearly 
added to band limited auxiliary data before transmission.

Filed: 1990-02-10
Abstract: Zur Erkennung und Bewertung von Schaumentwicklung auf 
oder in einer Flüssigkeit wird das Leitfähigkeitssignal 
(18) einer im Schaum befindlichen Leitfähigkeitsmeß­
einrichtung benutzt. Dieses Signal wird in digitaler 
Form von einem Signalprozessor einer Frequenzanalyse 
unterzogen. Wenn eine Frequenzkomponente oder eine 
charakteristische Frequenz des Signalspektrums oberhalb 
einer unteren Grenzfrequenz liegt, wird dies als Krite­
rium für übermäßige Schaumentwicklung verwertet. Der 
Signalprozessor bildet ferner die Hüllkurven (19,20) 
des Leitfähigkeitssignals (18). Ein weiteres Kriterium 
für Schaumerkennung besteht darin, daß die Differenz 
zwischen beiden Hüllkurven einen vorgegebenen Grenzwert 
übersteigt. Die Erfindung ermöglicht nicht nur die Er­
kennung von Schaum sondern zugleich eine Bewertung des 
Schäumungsvorgangs. Es kann ein Regelsignal erzeugt

Title: Process for impregnation of glass fiber reinforcement with thermoplastic resins and for producing articles from the impregnated glass fiber
IPC: B29C70/50
Filed: 1990-02-23
Abstract: A process for impregnating a glass fiber mat (18) with a 
resin (16), and for producing composite structures having impreg­
nated glass fibers, is provided which substantially reduces 
the number of voids in the resulting structure, provides fast 
and efficient heating of the materials, and requires low cap­
ital cost equipment to perform the process. The process 
includes heating a glass fiber mat (18) and an RF-sensitive resin (16) 
in a radio frequency electromagnetic field to quickly heat 
the mat and resin, the resin flowing into voids in the glass 
fiber mat, thereby impregnating the mat; forming the result­
ing composite structure into a desired end shape; and cooling 
the structure. Reduction in the number of voids is advanta­
geously accomplished by impregnating the resin into the mat 
under vacuum, which removes air and decomposition products 
which result from the RF heating of the resin. Impregnation, 
molding of the shape, and cooling of the structure may all be 
performed in a mold if desired, and elongated profiled parts 
may be continuously produced from elongated sheet stock by 
passing the heated structure through roll forming dies.
