Abstract: A novel conveyor belt is described. This novel conveyor belt consists of a traditional conveyor belt made of metallic wires in which these metallic wires can have, in cross-section, any convenient shape and in which the holes or spaces between the wires contain a solid substance. The metallic wires and the solid substance are preferably refractory. In order to obtain the belt with solid substance in its holes, in the said holes between the wires a plastic or liquid substance, as for example mortar, clay or similar products, is introduced, which posteriorly will harden by drying or setting or by drying and firing at a high temperature. The conveyor belt according to the invention is destined essentially for the continous cellular glass manufacturing.

 When compounds of the type  n = 0 are prepared, the hydroxymethyl group of 5-hydroxymethylfurfural (HMF) is first converted into a derivative and the aldehyde group is reacted with malonitrile, or, alternatively, the aldehyde group is initially converted into a derivative, the hydroxymethyl group is then oxidised and reacted with malonitrile. The compounds of the type n = 1 are prepared by either condensing two substituted or unsubstituted 5-hydroxymethylfurfural molecules first with one molecule containing at least two NH2 groups and, after oxidation of the two hydroxymethyl groups with malonitrile or, alternatively, first two hydroxymethylfurfural molecules are linked with elimination of water and the reaction with0 the malonitrile is then carried out, or two substituted or unsubstituted hydroxymethylfurfurals are linked via a two-carbon bridge by a benzoin addition reaction, the hydroxymethyl groups on the furan ring are then oxidised and reacted with malonitrile. The furan derivatives can be used directly or in the form of their cycloaddition products for various applications in the electrooptical sector, for example for the production of optical data recording systems or organic electrically conducting substances or electron transfer catalysts.

Abstract: Disclosed is a method for encoding a sequence of data bits (B1-B5) which have a logical in value or out value (1, 0), according to which said data bits (B1-B5) are arranged in a sequence of time slot frames (FR1-FR5) comprising time slots (ZS11-ZS14) which can accept an in value or out value (Z1, Z0). The encoding in a time slot frame is done in such a way that at least one time slot is pre-assigned an out value, the time slots that have not been pre-assigned a value are assigned an in value or out value so as to form the logical in value or out value of a data bit, and a time slot with an in value is followed by at least one time slot with an out value. The invention also relates to an identification system (IS) comprising a writing/reading device (SLG) and at least one mobile memory (DT1-DT3) for carrying out the inventive method. Said method has the advantage of being able to immediately detect a collision (C) when a data bit is complementarily encoded in a corresponding time slot frame. The inventive method can be used in an advantageous manner in the 13.56 MHz ISM frequency band for contactless data transmission through inductive coupling.
