L'invention concerne une composition à matrice polyamide et phase dispersée de polyoléfine, dans laquelle le polyamide a une température de fusion inférieurè à celle du polycapronamide et la phase dispersée est constituée d'au moins une polyoléfine choisie parmi les polyoléfines fonctionnalisées et les polyoléfines non fonctionnalisées. Avantageusement, le polyamide est un copolymère de caprolacta...

Compositions and processing conditions are disclosed for the production by rotomolding of polypropylene foams, hither to satisfactorily produced only by injection molding and extrusion molding. Rheological properties of the polypropylene resin, processing conditions and choice of composition of the chemical blowing agent were found to play important roles in obtaining high quality polypropylene fo...

A first substrate has a plurality of bumps and a second substrate has a plurality of openings at positions in registration with the plurality of bumps when the first and second substrates are placed one on top of the other in a confronting manner. The first and second substrates are put together by fusing a sealing wall formed on the second substrate, to hermetically seal an electronic device lyin...

Described herein is a combined process for improved hydrotreating of diesel fuels, in which the feed to be hydrotreated is pretreated with a selective adsorbent prior to the hydrotreating step to remove polar materials, especially nitrogen containing compounds (N-compounds). By removing the N-compounds in this way, it is possible to achieve extremely high conversions of refractory sulphur compound...

Bonded screens such as vehicle windscreens (1) bonded to a supporting frame (5) by homogeneous bonding material (6) are released by firstly arranging energy delivery means (9) adjacent the screen and subsequently transmitting energy from the delivery means through the screen thereby to effect release of the screen (1) from the frame (5) by either causing degradation of some of the homogeneous bond...

An endless conveyor has a driven drum that rotates about its axis. A flexible band forms a helix by being wrapped around the drum. A fixed helical support supports the outer edge of the band. A secondary conveyor moves an endless series of stacking blocks. The stacking blocks are in frictional engagement with the drum to transfer driving forces from the drum to the blocks. The stacking blocks also...

The present invention is an efficient and improved dynamic home agent discovery algorithm and system to be used in a protocol for Internet or network communications. The present efficient and improved dynamic home agent discovery algorithm and system for a protocol more efficiently uses the wireless access, communications resources, and the network resources. If a failure or error occurs at a home...

A method, apparatus, and computer program product for determining a drop probability for use in a congestion control module located in a node in a network is disclosed. A weight value for determining a weighted moving average of a queue in a node is first systematically calculated. The weighted moving average is calculating and an average queue size for the node is determined based upon the weight...

A method, apparatus, and computer program product for modeling dynamics of a queue are disclosed. A queue law function can be used to determine a control function for use in a congestion control module in a network for dropping packets. A queue law function may be determined based upon traffic conditions in the network. First a quantity that is representative of the link utilization between first ...

Liquid nonaqueous detergent compositions for machine dishwashing which have high physical stability (settling behavior) and chemical stability (bleach decomposition) and which achieve good cleaning performance even without the use of large amounts of surfactant, comprise, in addition to further optional detergent ingredients, 20 to 50% by weight of one or more water-soluble builders, 1 to 25% by w...

Cet agencement est du type comprenant un réflecteur (2), un dispositif source (3) et un dispositif de traitement des signaux reçus par le dispositif source et est caractérisé en ce qu'il comporte ...

At least portions of steel battery casings or other current collectors in contact with a manganese dioxide layer in a zinc-manganese dioxide alkaline cell present to that layer surfaces which have been burnished in the presence of particles of a passivity inducing metal such as nickel. Typically, the particles are transferred from a plating layer on a surface of low carbon steel forming the casing...

The null intensity for each gas channel is approximated with the reference channel intensity multiplied by a function that approximates the reference value for the sensor as a function of temperature. A method for continuously determining the null intensity (I0) of a gas analyser comprising an IR emitter (1), a reference filter (3), an optical band pass filter (4), channels for the gases being ana...

The bits are distributed in a space with the dimension (i) and a given depth (m, n) in each dimension, where i, m and n are greater than 1. The bits are assigned coordinates (x1-xn, y1-yn) in each dimension and the number of bits with a given value are calculated in the same dimensions by keeping each coordinate in every second dimension constant. Digital information is then extracted via sums of ...

A lithium ion electrochemical cell having high charge/discharge capacity, long cycle life and exhibiting a reduced first cycle irreversible capacity, is described. The stated benefits are realized by the addition of at least one phosphonate additive to an electrolyte comprising an alkali metal salt dissolved in a solvent mixture that includes ethylene carbonate, dimethyl carbonate, ethylmethyl car...
