Process for the temperature stratification-free storage of a cryogenic liquid in a thermally insulated tank under gravitation conditions or under gravitation and movement conditions, which generate a liquid volume with a clearly limited, unmoving or only moderately moving liquid level as well as with a gas space located above it in the storage volume of the tank. Liquid is pumped off from the area...

A disposable diaper (1) of pants type has front and rear bodies (5, 6) bonded to each other by a series of welded zones (10) along transversely opposite sides of front and rear waist sections. The welded zones (10) are at least partially defined by patterns of V-shape or patterns of V-shape being devoid of a sharp point, both laid down transversely of the diaper, or patterns of an arc opening tran...

A process for making liquid polymers by condensing monomers and/or oligomers, mixing them with a catalyst where required, and dispersing the mixture via an atomising device to form small droplets suspended in a reaction chamber. The reagents are caused to polymerise in the dispersed state. The process is preferably carried out in a spray dryer using an atomising device and is particularly useful f...

A treatment system is described for treating waste water, comprising a container having an upper and a lower portion, at least one elongated hollow casing within the lower portion of the container, inlets, openings, or vents for aerating the treatment system and at least one distribution system for distributing the waste water entering the container into at least one treatment chamber defined by t...

A cable splice enclosure (10) including a pair of cover members (12,14) joined along a flexible hinge (62,64) and rotatable together about the hinge to enclose a cable splice (150) and secure to each other with latches along both side edges (16,18;92,94). Sealant material (120) disposed within central regions (32,34) of both covers environmentally seals the surfaces of the splice connection (154,1...

An electronic tag (10) receives a data message (18) that has a wake-up section (20) followed by a session section (22). The interrogation signal which carries the data message encodes the wake-up section (20) differently from the session section (22). A power manager (28) decodes the wake-up section (20) using a very low power decoder (34) that remains energized during a standby state. When the po...

A novel molded structure especially useful as a rigid, load-bearing structure, is provided. Also provided is a novel process for molding the structure, which may be in the form of a pallet. By the process, the structure is chilled as it is being formed. Recycled resins including contaminants of limited compatibility may be used.

In a time division multiple access mobile wireless telecommunication system, a base station has a plurality of frequencies with their priority order previously registered in a memory, selects, upon starting the operation, the frequency having the highest priority from frequencies not used by other wireless telecommunication systems, and initiates communications at the selected frequency. The base ...

A distributed feedback semiconductor laser selectively performs one of two oscillations in different polarization modes having different polarization planes. The laser includes a subtrate, a light waveguide formed on the substrate, which at least partially includes an active layer, a a diffraction grating formed around the waveguide, and an injecting unit for injecting a modulation current into a ...

Disclosed is a process for the formation of silicon carbide powder in which vaporized polysiloxanes are reacted and pyrolyzed in a single heating step to form silicon carbide powder. The process is simple, inexpensive and yields powder having desirable characteristics.

A method for the fabrication of printed pre-envelopes comprising the phases of: printing a multiplicity of pre-envelopes on a continuous substrate in side by side coupled format; separate the continuous substrate into sheets of coupled pre-envelopes while they are moving along a first axis of travel; separate and fold the individual pre-envelopes; after the separation and folding, move the individ...

This invention relates to a method and corresponding circuits for adaptive estimation of the pulsed response of a transmission channel by adaptive filtering. This estimation is performed using a least mean square (LMS) algorithm, in which the gain parameter is vectorial. This gain parameter is updated in stages so that the time changes in the transmission channel can be monitored effectively.

The present invention refers to a method for estimating the pulsed response of a transmission channel based on the prior transmission of a conditioning signal consisting of a maximum binary signal and the relevant circuits. With the benefit of the special characteristics of the conditioning signals used it is possible to obtain a zero order approximation of the estimate of the pulsed response of t...
