Filed: 1990-03-15
Abstract: A granular fill material (36) for use in a 
storage module (10) for the storing of nuclear and 
hazardous waste materials. The waste materials are 
packaged in a waste container (26) which is in turn 
deposited within the storage module (10), thereby creating 
a void space between the waste package or packages (26) 
and the interior sidewalls (16) of the module (10). The 
filler material (36) is reintroduced within the module 
(10) to fill within this void space, to immobilize the 
waste containers (26) within the module (10), and to 
provide a physical and chemical barrier around the waste 
containers (26). The granular filler material (36) 
comprises a sand filler, an absorbent clay such as Wyoming 
bentonite, and an organic liquid absorbent material such 
as Fuller's earth. Other constituents that can be mixed 
in the granular fill material are an acid neutralizing 
material such as quicklime or slaked lime, and a getter 
material for absorbing radionuclides. The granular fill 
material also advantageously enhances the retrievability 
of waste packages (26) within the module (10) should such 
retrieval become necessary.

Patent EP-0402345-A3 (EP)
IPC: G01S13/60
Filed: 1990-05-21
Abstract: Die Erfindung betrifft ein System zur Geschwindigkeits- und Rich­
tungskontrolle für Kraftfahrzeuge und zwar derart, daß am Fahr­
zeug eine Sende- (2), eine Empfangs- (3) sowie eine Prozessorein­
heit (5) installiert werden, die mit energielosen Reflektorein­
richtungen im Fahrbahnbelag (9) in Wechselwirkung stehen. Der 
Sender emittiert kontinuierlich elektromagnetische Wellen geeig­
neter Wellenlänge im Zentimeterbereich mit ausgeprägter Richtcha­
rakteristik unter einem spitzen Winkel, zum Beispiel 45 Grad, in 
Achsrichtung auf die Fahrbahn (9). Je nach zulässiger Höchstge­
schwindigkeit werden in der Fahrbahn (9) quer zur Fahrtrichtung 
in, den jeweils vorgegebenen Geschwindigkeitslimits entsprechen­
den, Abständen Reflexionsbänder verlegt. Die Hauptreflexionsrich­
tung der Reflexionsbänder weist mit der Fahrbahnoberfläche einen 
spitzen Winkel auf. Wird zwischen dem Registrieren von zwei auf­
einanderfolgenden Impulsen ein vorgegebenes oberes Zeitintervall 
unterschritten, reagiert das System mit geschwindigkeitsmindern­
den Strategien im oder am Fahrzeug. Bei Geschwindigkeitsüber­
schreitungen können durch das System auf einer Punktewertkarte, 
das heißt auf einem elektronischen Führerschein in Form einer 
intelligenten Chipkarte, Punkte abgezogen und beim Unterschreiten 
von Geschwindigkeitslimits Punkte in geringem Ausmaß gutgeschrie­
ben werden. Auf diese Weise kann eine völlig dezentrale und 
anonyme sowie verkehrserzieherische Form der Strafpunkteverwal­
tung erzielt werden. Wenn die Zeit zwischen zwei Impulsen kleiner 
als ein vorgegebener unterer Grenzwert ist, wird dies vom Prozes­
sor (5) als ein krasses Ereignis interpretiert. Infolge der 
strengen Fixierung des Systems auf eine Fahrtrichtung können nach 
diesem Prinzip Fahrzeugbewegungen in eine falsche bzw. unzulässi­
ge Richtung - wie etwa falsches Auffahren auf eine Autobahn - vom 
System eindeutig erkannt und mit entsprechenden Reaktionen beant­
wortet werden. Dazu werden Reflexionsstreifen auf Einbahnstraßen 
in entsprechend geringen Abständen verlegt und zwar derart, daß 
die an den Streifen reflektierten elektromagnetischen Wellen nur 
an den Empfänger eines solchen Fahrzeuges, das sich in der unzu­
lässigen Richtung bewegt, gelangen können. Wird eine Straße unter 
diesen Voraussetzungen in der erlaubten bzw. vorgeschriebenen 
Richtung befahren, kommt es wegen der erwähnten Ausrichtung der 
Reflektoren (6) zu keiner Registrierung eines krassen Ereignis­
ses. Natürlich ist es möglich, in der erlaubten Richtung gleich­
zeitig - und völlig unabhängig von der Richtungskontrolle - eine 
Geschwindigkeitsanzeige bzw. Geschwindigkeitskontrolle nach 
diesem System zu installieren.

Abstract: A multi-colored pixel for a twisted nematic liquid crystal display including red, green, and blue subpixels, wherein each subpixel includes a pair of substrates, a pair of polarizers, opposing electrodes, and a color personalized retardation film which compensates for the different wavelength of each color. The personalized retardation films of the different color subpixels results in elimination of the multi-gap approach and substantially eliminates the problem of different color leakages at different viewing angles, including normal. Also, one polymer based element, preferably a polyimide, functions as both a color filter and a retardation film in certain embodiments of this invention. <IMAGE>

Inventor: NOCHEBUENA ROGELIO F
IPC: B41J2/46
Filed: 1994-11-28
Abstract: A line printing system which utilizes an array (80) of asymmetrical Fabry-Perot light
valves (C 1 ,C 2  etc) for simultaneously transferring all pixel information of one raster line onto a
photoreceptor (88). The number of elements of the light valve array used in this invention is
equal to the number of pixels on a raster line. The pixel information is applied to elements of the
light valve array in a parallel format with information representing each pixel applied to one
elemental light valve of the array. The array is illuminated by a wedge-shaped incident light beam
(64) forming a focussed line image. Depending on the information state of each pixel, each
corresponding element will be activated to absorb incident light or left in its neutral state to
reflect the light. Light reflected by neutral elements (C 2 ,C 5 ) will be directed onto the
photoreceptor. In this fashion, the photoreceptor simultaneously receives the pixel information
for the entire raster line. In another mode, the elements will be activated to reflect the light beam
and will be left in their neutral state to absorb the light beam.
