Patent EP-0778077-A2 (EP)
Inventor: SAKELLAROPOULOS G P
IPC: C08L81/06

Abstract: Preparation, testing and examination of gas separation polymer membranes prepared from mixtures of the polysulfone Udel P-1700 and the aromatic polyimide Matrimid 5218. 
     Polysulfone and polyimide proved to be completely miscible polymers as confirmed from optical microscopy, glass transition temperatures and spectroscopy analyses of the prepared mixtures. The complete miscibility permits the preparation of symmetric and asymmetric blend membranes in any proportion (1-99% wt) of polysulfone and polyimide. 
     Permeability measurements for various gases of industrial importance (such as carbon dioxide and monoxide, hydrogen, oxygen, nitrogen etc.) through polysulfone-polyimide blend membranes showed significant permeability improvements, compared to pure polyimides, with a minor change in their selectivity. Blend membranes were considerably more resistant to the plasticization phenomenon compared with those of pure polyimides. 
     Therefore, the use of polysulfone-polyimide polymer blends for the preparation of gas separation membranes offers a new, economic, high performance technical solution for application in the separation of industrial gases, with the typical compositions of gaseous mixtures encountered in the recovery of hydrogen from refinery gases, the separation of hydrogen from ammonia synthesis purge gases, the separation of gaseous products in coal, lignite and other solid fuel gasification processes, the separation of carbon dioxide from the exhaust gases of power generating stations using solid, liquid, gas or biomass as fuels, air separation for the production of nitrogen and/or oxygen enriched streams etc.

Abstract: A frequency synthesizer consists of a voltage-controlled oscillator and a frequency division and distribution section. The frequency division and distribution section, which splits an oscillation signal of the voltage-controlled oscillator into a transmission modulation local oscillation signal and a reception second local oscillation signal while frequency-dividing the oscillation signal of the voltage-controlled oscillator, includes two pairs of frequency dividers and two switches. The frequency division numbers of the two pairs of frequency dividers are so set as to accommodate all the combinations of mobile communications systems and the transmission modulation local oscillation signal/reception second local oscillation signal. The two switches are switched in accordance with a mobile communications system for which a mobile transceiver is operating. The two local oscillation signals are input to a quadrature modulator and a quadrature demodulator, respectively.

Abstract: A water absorbing agent comprising water
absorbent resin particles having a particle size
of 1000 µm or less, with a two-peak mode particle
size distribution, which has an inflection point
in the range of 750 to 250 µm particle size prepared
by plotting the mass cumulative content percentage
from the larger side of the particle size of the
particle size distribution on a logarithmic normal
probability paper; and an absorbent material
utilizing the water absorbing agent. Since the
water absorbing agent of the present invention
applied in an absorbent material can realize
excellent absorption rate of a liquid and planar
diffusion, an absorbent material with an excellent
surface dryness can be obtained even for a long time
use or when the ratio of the water absorbent resin
is high due to a thin shape of the product, without
the risk of leakage. Accordingly, the water
absorbing agent of the present invention can be
preferably used in an absorbent material such as
a disposable diaper.

Abstract: A method of encrypting data is described in which a random
variable (6A-6D) is generated in binary digital form. A
first set of data (8A-8J) representing a plaintext message
in binary digital form is combined with the random variable
(6A-6D) to generate a second data set (9A-9J) in binary
digital form. The data bits representing the random
variable (6A-6D) are inserted into the second data set (9A-9J)
according to a first predetermined set of rules and the
order of the data bits in the second data set (9A-9J) is
altered according to a second predetermined set of rules.
A third data set (17A-17N) for transmission as a ciphertext
message is thus generated.

Abstract: L'invention a trait à un appareil permettant d'appliquer un courant électrique à un tissu biologique, la peau, un os ou un muscle par exemple. Un boîtier portatif (10) peut être alimenté par une batterie (24) ou un cordon d'alimentation relié à une source de courant électrique alternatif ou continu. Un amplificateur (26) produit un courant continu à haute tension et une unité de commande (22), une modulation carrée de sortie de qualité élevée. Cette modulation est délivrée en sortie vers un ensemble électrode (12) en contact électrique avec le tissu biologique. Cet ensemble, qui comprend, à tout le moins, une électrode négative (16) et une électrode positive (14), et qui produit un courant électrique passant par le tissu biologique entre les électrodes positive et négative, est susceptible de se déplacer sur le tissu biologique de sorte que le trajet du courant est toujours changeant. Cet ensemble peut, de surcroît, comprendre plusieurs électrodes positives et négatives afin de créer plusieurs trajets de courant dans le tissu biologique. L'unité de commande peut modifier, de manière sélective, des fonctions de signal de sortie comme la fonction d'amplitude, de fréquence d'impulsion, de vitesse de balayage, de fréquence et de vitesse de balayage des fréquences, afin de produire différents courants électriques en direction du tissu biologique. Un système de visualisation en liaison avec l'unité de commande indique les fonctions de signal de sortie et porte des commandes permettant de modifier de manière sélective ces fonctions.

Abstract: A system for tracking an object (for example tracking an automobile as it moves over streets) using an electronic map and a GPS receiver. The GPS receiver accepts data from a number of satellites and determines a GPS derived position and velocity. Based on the previous position of the object, the GPS derived position, the velocity, the DOP and the continuity of satellites for which data is received, the system determines whether the GPS data is reliable. If the GPS data is reliable, the previous position of the object is updated to the GPS derived position. The updated position is then matched to a map of roads.
