Abstract: L'invention est une méthode qui permet d'améliorer la probabilité d'atteinte de l'objectif des projectiles programmables.   cette fin, la distance de désagrégation optimale prédéterminée (Dz) entre un point de désagrégation (Pz) du projectile (18) et un point d'impact (Pf) sur la cible est maintenue constante par la correction du temps de désagrégation (Tz) du projectile (18). La correction est effectuée en ajoutant au temps de désagrégation (Tz) un facteur de correction qui est multiplié par une différence de vitesses, cette dernière étant la différence entre la vitesse mesurée du projectile et sa vitesse moyenne, celle-ci étant la valeur moyenne des vitesses d'un certain nombre de projectiles précédemment lancés avec succès.

Title: Uniform stacking cup lid
Inventor: RUSH JONATHAN EDWARD
IPC: B65D43/02
Filed: 1996-11-26
Abstract: A thin walled lid formed of a thermoplastic material having a generally circular center portion and an outer run portion which fits over the cup bead and includes an integral peripheral skirt which makes up the outer side wall of the lid is disclosed. Located between the rim portion and the center portion is a recess or annular trough with an inner wall and an outer wall. The outer wall is separated into two shelves and three vertical sections. The lower shelf serves as a receiver ring upon which the lid above rests. The short vertical section located above the receiver ring effectively prevents any lateral movement of the lid above, while the lowest wall section forms the stacking ring and generally has a negative slope toward the lid skirt. Spaced periodically around the circumference of the stacking ring are positive draft flutes which have a positive slope away from the skirt and toward the center of the lid. The recess has a generally flat bottom which connects the stacking ring to the inner wall. The corner of the lid where the stacking ring and the recess bottom join rests in the receiver ring of the next lower lid in the stackto provide uniform nesting and full circumferential support. The inner wall of the recess has a positive slope and connects the bottom of the recess with the generally flat center portion. In an alternative embodiment, the negative stack ring and the receiver ring are provided on the inner wall of the lid. There are no positive draft flutes provided, in that as the plastic cools during the thermoforming process the negative stack ring will shrink towards the lid centera sufficient distance to allow the lid to clear the undercut of the mold during stripping.

Title: Multiband mobile telephone system
Inventor: EINOLA HEIKKI
IPC: H04W88/06
Filed: 1996-05-15
Abstract: The invention relates to a mobile communication system that is a multiband network comprising a plurality of bands. The 900 MHz frequency range of the GSM system and the 1800 MHz frequency range of the DCS system is used as an example. In accordance with the invention, the network transmits to the mobile station information not only on the frequencies of another band to be monitored, but also on how many monitored adjacent band frequencies the mobile station should report. The number of adjacent band frequencies to be reported on, given in the information, is not constant, but the network changes it as needed. In this way the network obtains adequate information on the adjacent band frequencies to perform handover between the bands.

Title: Erythro-hydroxynonyladenine analogs with enhanced lipophilic and anti-ischemia traits
Inventor: BARANKIEWICZ JERZY A
IPC: A61K31/52
Filed: 1996-02-12
Abstract: An epoxy-silicate nanocomposite is prepared by dispersing an organically modified smectite-type clay in an epoxy resin together with diglycidyl ether of bisphenol-A (DGEBA), and curing in the presence of either nadic methyl anhydride (NMA), and/or benzyldimethyl amine (BDMA), and/or boron trifluoride monoethylamine (BTFA) at 100-200 ~C. Molecular dispersion of the layered silicate within the crosslinked epoxy matrix is obtained, with smectite layer spacings of 100.ANG. or more and good wetting of the silicate surface by the epoxy matrix. The curing reaction involves the functional groups of the alkylammonium ions located in the galleries of the organically modified clay, which participate in the crosslinking reaction and result in direct attachment of the polymer network to the molecularly dispersed silicate layers. The nanocomposite exhibits a broadened Tg at slightly higher temperature than the unmodified epoxy. The dynamic storage modulus of the nanocomposite was considerably higher in the glassy region and very much higher in the rubbery plateau region when compared to such modulus in the unmodified epoxy.

Abstract: A phase shifter/modulator which provides linear phase control of a microwave continuous wave carrier signal. Linear phase shift range  in excess  of  360 degrees  is provided  as  a  result  of  linear  variation  in  control voltage.   A reference signal,  at a subharmonic of the output carrier signal frequency, is injected into a highly linear fractional range reflection type phase shifter. This fractional phase modulated signal is input to a field effect transistor (FET) based frequency/phase multiplier. The frequency/phase multiplier translates the subharmonic reference signal to the desired output carrier frequency with the full 360 degree phase shift range imposed on the output carrier signal.

Title: Frequency cancelling system and method
Inventor: PALMER JOHN P
IPC: H04B1/40
Filed: 1997-09-18
Abstract: A  frequency  cancelling  system  is  disclosed which improves reception of a communication signal which is  transmitted  at  a  communication frequency  in  the presence of an interference signal which occurs at the same communication frequency.  The frequency cancelling system generates a reference signal at the communication frequency,  and  adjusts  the  reference  signal  to  be opposite  in  phase  and  equal  in  amplitude  to  the interference  signal.   The  reference  signal  and  the communication  signal  are  then  combined  to  cancel  the interference  signal.   In  a  preferred  embodiment,  the reference signal  is generated from the same source as that   from  which  the   interference   signal   arises. Preferably,  the interference signal is received during an interval  in which the communication signal  is not being transmitted, and the reference signal is adjusted to be opposite in phase and equal in amplitude to the interference signal during that interval.
