Title: Convertisseur de couple hydrodynamique muni de moyens   de pontage

Abstract: Convertisseur de couple hydrodynamique muni de moyens de pontage. Le piston de commande est soumis à la pression de l'enceinte dans la position de la figure. Le fluide hydraulique alimenté par l'arbre de transmission pénètre dans l'enceinte par les passages et dans la chambre de commande par l'orifice calibré. La sortie de la chambre de commande est bloquée par l'électrovanne. La pression dans l'enceinte est la même que la pression dans la chambre de commande. Le ressort entraîne donc un déplacement du piston de commande l'ensemble fonctionnant en convertisseur de couple. Dans la position inverse de l'éelctrovanne, la pression régnant dans l'enceinte dont la sortie est obturée s'exerce sur le piston de commande à l'encontre de la force du ressort. La pression dans la chambre de commande est basse et le serrage de la garniture provoque le pontage.

Abstract: TRANSMISSION OF DATA WITH A VIDEO SIGNAL Abstract of the Disclosure The horizontal line synchronizing pulses of a video signal are selectively replaced with a video signal blanking level in dependence upon bits of data, whereby the data is transmitted with the video signal. Such data transmission is particularly applicable to a pay TV system in which the video signal is scrambled, because the selective absence of horizontal line synchronizing pulses enhances the video signal scrambling. In this case the data can comprise information relating to the scrambling of the video signal.

Abstract: ABSTRACT OF THE DISCLOSURE      A horizontal shell boiler has a horizontal and cylindrical furnace section in which a fluidised bed is situated.   At one end the furnace section communicates with a flue gas transfer section connected to flue tubes extending horizontally through the boiler fluid above and around the furnace section.   The furnace section is divided into two portions by a row of inclined water tubes the portion above the water tubes for acting as a flue gas transfer portion.   Combustion gases leave the fluidised bed in a vertical direction and pass between the inclined water tubes.  The gases then travel horizontally along the flue gas transfer portion to the flue gas transfer section and do not have any significant tendency to entrain the material of the fluidised bed.

Abstract: ABSTRACT OF THE DISCLOSURE         Time base correcting apparatus is provided for a digital signal supplied to such apparatus in the form of successive data blocks with each data block including plural data words.  A memory is provided, having plural addressable storage locations, each adapted to store a respective data block.  A write address generator generates write-in addresses to address particular storage locations into which the supplied data blocks are written; and an error detector detects whether the supplied data block contains an error.  If no error is detected, a write-in circuit writes that data block into the addressed storage location; but if an error is detected, the data block is inhibited from being stored.  An error store also is provided to store an error flag which is, for example, reset when the non-erroneous data block is written into the addressed storage location, and is set when an error in that data block is detected.   A read address generator generates read-out addresses to address those storage locations from which storage data blocks are read.  When the contents of an addressed storage location are read out, the error flag associated with that data block is set regardless of its actual condition, thereby preventing subsequent re-use of the contents of that addressed storage location in the event that the data block stored therein is not replaced but is attempted to be re-read.     -i-

With this arrester (1) the electrical influence of this socket (2) is to be utilized to provide arres-ters with even further improved life span.  For this the inven-tion provides that the socket (2) is at ground potential, that the ignition line (6) is electrically conductively connected to the electrode (3) which is formed as a wire or pin electrode and ends in a rear space of the other electrode (4) in which low vapor deposition occurs, the electrode being formed as a perforated or hollow electrode, whereby the two electrodes (3,4) are arranged in such a way that an approximately equal spacing is formed between the electrodes (3,4) and between the perforated electrode (4) and the ignition line (6).  The invention is used with gas discharge overvoltage arresters.
