Abstract: Um bei Absorptionskühlmöbeln die Raumausnutzung zu verbessern und die Wirksamkeit der Kuhlung zu erhöhen, wird eine besondere Gestaltung des Verdampfer-Rippenkörpers (20) vorgeschlagen, der aus einer Grundplatte (22) und aus damit verbundenen Kühlrippen (23) besteht. Die Grundplatte liegt parallel zu einer Wand des Kühlmöbels (1) und weist eine gegen den zu kühlenden Raum (3) gerichtete -Ausbuchtung (21) auf, in welche das horizontal oder leicht geneigt verlaufende Verdampferrohr (17) des Kühlaggregates (1o) hineinpaßt. Oberhalb und/oder unterhalb der Ausbuchtung (21) ragen mit der Grundplatte wärmeleitend verbundene Kühlrippen in den zu kühlenden Raum. Eine solche Formgebung des Rippenkörpers begünstigt den konvektiven Wärmeübergang. Ferner benötigt bei solcher Gestaltung das Verdampferrohr keinen zusätzlichen Raum bzw. Tiefe, weil es innerhalb des Rippenkörperquerschnittes liegt.

Abstract: A method of fabricating a field effect transistor comprising the steps of forming an active layer of semiconductor material eg GaAs, over a surface of a first substrate (1) of semiconductor material, eg also GaAs forming a gate electrode (7) on the surface of the active layer (4). applying a second substrate (11) of insulating material to the surface of this structure, removing the first substrate, and forming source and drain electrodes (16,17) on the opposite surface of the active layer to the gate electrode. To facilitate removal of the GaAs first substrate by selective etching, a buffer layer (2) of GaAIAs resistant to the GaAs etchant, may be formed between the active layer and the first substrate, which buffer layer is removed, following removal of the first substrate. using a selective etchant to which the GaAs active layer is resistant. A second gate electrode may be formed on the opposite surface of the active layer to that on which the first gate electrode is formed. The technique is particularly applicable to high frequency FET devices.

Abstract: The heating of the powder of rigid polyvinyl chloride in an extrusion machine of known type presents difficulties and causes burning. According to the invention this is avoided by introducing continuously the raw material in the form of powder after intense mixing with stabilizer and slides in the feed opening of a monoscrew extruder. The said monoscrew extruder has eight different zones: an introduction zone preferably without heating; a slightly heated compression zone; a heated homogenization zone (H), a plasticizing zone; a heated decompression zone (D); a heated degasifying zone (G); a heated compression zone (K I ) and a heated expulsion zone. 
     For the plasticizing there is inserted in the extrusion screw before the decompression zone (D) a ring (3) provided with calibrated bores (4 and 5) which obstruct, that is, delay the flow so as to plasticize it without having to increase the temperature.

Abstract: The invention relates to a process for inhibiting the corrosion of an installation, made of a material chosen from amongst the metals which are less noble than hydrogen, and their alloys, in contact with an acid bath containing an alkylpyridinium chloride. A soluble cyanide complex, which is capable of forming an insoluble compound by reacting with ferric ions in the bath, is added to the bath so as to limit the concentration of the ferric ions in the bath to a maximum of 30 mg/kg. The content of ferric ions in the bath is controlled by means of a potentiometric measurement so as to bring the potential of the bath into the region of a predetermined value. The invention applies in particular to the treatment of baths for cleaning or descaling steel installations.
