A considerable portion of the gas developed by fermentation in an anaerobic purification equipment for waste water, together with buoyant sludge, is collected by at least one additional collecting system (5), before it may reach the upper part of the reactor. This additional collecting system is fitted at a distance below the collecting system (6) fitted as usual just below the level of one or mor...

The method for end-to-end joining of the edges of a rubberised fabric formed from reinforcing elements which are parallel to each other and separated by a distance p, consists in injecting, under pressure and hot, between the reinforcing elements of the edges separated by a distance having a value d greater than 1.5 p, a rubber mix having cohesion and green strength properties superior to the same...

The method is applicable to manufacturing esp. 1 transistor - 1 capacitor D-RAM cell. The first process is to form a field oxide layer (16) and channel stop region (18). The second process is to etch nitrogenated silicon layer (12) and to inject intrinsic substance. The third process is to diffuse the intrinsic substance under the minifield oxide layer (30). The fourth process is to form a sou...

A process for production of ammonia wherein stoichiometrically hydrogen-lean synthesis gas is reacted over a highly active synthesis catalyst.

In a television receiver with a device for suppressing flicker disturbances in the reproduced television picture, in which the vertical frequency during the reproduction is increased compared with the vertical frequency during the transmission, transmitted video signals are converted into video signals to be reproduced with increased vertical frequency as a function of the presence of essentially ...

In a television receiver comprising a device for suppressing flicker disturbances in the reproduced television picture, transmitted video signals are converted into video signals to be reproduced with the same vertical frequency which form a continuous raster without interlace. The video signals to be reproduced are derived in accordance with a first or in accordance with a second method in depend...

Inventia se refera la o ansa pentru pistol de lipit. Ansa, conform inventiei, este alcatuita din tabla de cupru avînd forma literei U cu doua capete care se prind sub saibele pistonului de lipit si cu baza usor îndoita la mijloc spre exterior si prelungita cu un vîrf cu care se executa lipiturile.

Inventia se refera la o schema de protectie a scurtcircuitelor pe sarcina la limitatoarele inductive de proximitate tip LP la care pe un rezistor de valoare mica, înseriat cu tranzistorul final si cu sarcina se obtine o cadere de tensiune proportionala cu curentul de sarcina care în momentul producerii scurtcircuitelor aduce în conductie un tranzistor prin care se produce amorsarea unui tiristor s...

For drying a gaseous stream in thermally regenerable cyclically connected adsorbers wherein the gaseous stream contains components polymerizable under regeneration conditions, the bed is subdivided into several layers having different adsorbents. The first layer consists essentially of an adsorbent, e.g., zeolite type 4A, having a higher adsorption capacity for polymerizable compounds than the sec...

After division in the prism, the light beams produced by the amplifier are transmitted in two identical pictures for projection by a transport system in the oculars of the binoculars. The beams produced by the light amplifier are projected over an infinite distance using a lens, the aperture of which is divided into two halves by dividing prisms, so that in each ocular the picture is produced. Two...
