The invention relates to a biodegradable foil made from a low salt content hydroxypropylether solution of a starch containing at least 70 % amylose having a median molecular weight from between about 10 5 to about 2 x 10 7, a polydispersity from about 2 to about 8, a degree of substitution from about .1 to about .5, and a substantially equal substituent distribution between C2/C3 and C6 bond sites...

THE WARP ENDS ARE GATHERED TO FORM THE SHAPE OF ROPE,AND ARE APPLIED FALSE TWIST AND STORED IN A STATIONARY CONTAINER. AFTER THE FULL CONTAINER IS MOUNTED IN A LOOM, THE FALSELY-TWISTED WARP IS UNWOUND FROM THE STATIONARY CONTAINER,AND THE FALSE TWIST IN THE WARP DISAPPEARS AND THEREFORE THE WARP IS RESTORED TO TRADITIONAL FORM OF WARP. AS THE CONTAINERS ARE ALWAYS KEPT STATIONARY,IT IS MADE POSSI...

A topsheet for body fluids absorbent article having a plurality of liquid-pervious apertures 6, the topsheet including an upper fibrous layer having a relatively low density and a lower fibrous layer having a relatively high density. Around each of the apertures 6, the first and second fibrous layers 11, 12 are integrated together so that the topsheet 2 has a density progressively increasing from ...

The invention relates to a packet radio system comprising a network part (100, 102, 132, 140), at least one subscriber terminal (150) and a bi-directional radio connection (170) between the network part (100, 102, 132, 140) and the subscriber terminal (150), where the bi-directional radio connection (170) is used for connection establishment and packet transmission, each subscriber terminal is pro...

Inter-frequency handoffs in a CDMA or other wireless communication system are controlled using a noise-limited coverage trigger metric which is able to distinguish between same-frequency cell boundaries and other-frequency cell boundaries in the system. The trigger metric may be generated as a function of an average signal-to-noise measure for pilot signals received at a mobile station of the syst...

A method for operating a wireless telecommunications system whereby communication channels are efficiently allocated to cells of the system is provided. In accordance with an illustrative embodiment of the present method, call demand information is obtained for each cell in the wireless system and converted to a channel demand. Once the channel demand for each cell is known, a tentative channel al...

Provided herein is an electrochemical lignin treatment method for depolymerizing lignin polymers or lignin-like polymers to monomeric or short chain oligomeric components. The lignin or lignin-like polymer is introduced in a chamber containing a cathode, current is applied to the cathode material so as to generate in-situ chemisorbed hydrogen and perform hydrogenolysis of said lignin or lignin-lik...

A method of cleaning and sanitizing maple sap lines, comprising the steps of injecting ozone into water; and then passing the water injected with ozone through maple sap lines. An apparatus is also disclosed for implementing the method.

An optical scan module, for example for an optical scanner, includes an integrally molded plastics material member which defines not only the laser focusing lens, but also the laser focusing aperture and the collection mirror. In addition, the molded member may act to house and to locate both a semiconductor laser and a photodetector, thereby ensuring easy and accurate placement of those elements ...

A method for analysing a thermal paint includes the step of defining a colour space in at least two dimensions, the dimensions representing different colours and/or luminance values. The location of reference points, representing calibration data, is defined within the colour space for comparison with colour information relating to a part to be analysed. Each pixel of an image of the part to be an...

A method for producing a spinet type lithium manganese complex oxide comprises the steps of: synthesizing a spinet type lithium manganese complex oxide represented by a general formula of Li(Mn2-x Li x)O4 (wherein x is defined by the relation of 0 ~ x ~ 0.08) by a spray pyrolysis method; and subjecting the oxide to a heat treatment at a temperature of T.degree.C (T is defined by the relation of T ...

La présente invention a pour objet une émulsion eau-dans-huile stable, à usage cosmétique, pharmaceutique ou hygiénique, comprenant une phase aqueuse et une phase grasse comprenant une huile de silicone, caractérisée par le fait qu'elle comprend au moins une silicone oxyalkylénée substituée en .alpha.-.omega., l'émulsion ayant une viscosité allant de 100 cps à 200 poises, à 25 .degree.C et au taux...

In a frequency carrier arrangement method, first and second frequency bands to which frequency carriers used for uplink and downlink communications between the first and second base stations and the mobile stations are arranged such that frequencies do not overlap. A first frequency carrier group constituted by at least one frequency carrier and a second frequency carrier group constituted by at l...

To optimize the number of optical gate switches required by an optical switching apparatus which comprises an optical space switch and wavelength selectors, the following process as a preliminary process of introducing optical signals into the optical space switch, is carried out. In detail, the preliminary process is optically converting the optical signals in relation to the number of input port...
