An apparatus and method for compressing a sequence of frames (from 1) having at least first and second information-bearing media components selects a plurality of representative frames (by 4) from among the sequence of frames. The representative frames represent information contained in the first information-bearing media component. A correspondence is then formed between each of the representativ...

Ce procédé est caractérisé en ce que l'on injecte un matériau inerte d'origine minérale dans la boue activée, ce matériau étant immédiatement dispersé de manière homogène dans la boue activée, afin de créer une culture mixte comportant à la fois et en un seul floc bactérien, des espèces hétérotrophes libres et autotrophes partiellement fixées sur les particules dudit matériau à l'intérieur du floc...

An arrangement for overmolding an article which extends beyond the mold cavity itself is provided with first and second mold portions arranged on opposing sides of a first portion of the article, which is contained within the mold cavity. A portion of deformable material is disposed in the region where the mold halves interface with a second portion of the article, which extends beyond the mold ca...

A solar cell system for supplying electric energy from solar cells to loads. This solar cell system includes solar cells for converting light energy into electric energy, an electric double layer capacitor for storing the electric energy from the solar cells, and a discharge controller for causing the electric double layer capacitor to discharge electric energy to the loads intermittently in pred...

A composting device comprises (A) a collection region for compostible material, in the form of a cylindrical shaped perforated sheet (pref. steel) vessel which is open at both ends; (B) a perforated hose extending between the upper and lower sections of the collection region; and (C) a thermal insulation covering only approx. the top half of the vessel and contg. a sealable lid opening in its vess...

The tube materia is locked on the pallet with a paper strip or other film, which is laid in a coil around the material. The tube material is fed to the device via a transport track to a compartment (5) or corresp. device where it is delivered by a picking arm. The layout of the locking paper strip is controlled by a programme, which is partly selected dependent upon the load and the pallet being u...
