Abstract: Procédé en deux étapes de fabrication d'aérogels transparents ayant une masse volumique inférieure à 0,003 g/cm3 et pouvant dépasser à 0,8 g/cm3, selon un procédé sol/gel par extraction surcritique. On peut diluer un produit intermédiaire d'oxyde de métal condensé obtenu à l'aide de réactif purifié afin de produire des aérogels stables d'une masse volumique inférieure à 0,02 g/cm3, y compris des masses volumiques inférieures à 0,003 g/cm3. L'extraction surcritique directe à haute température des alcogels dilués produit des aérogels hydrophobes stables dans des conditions d'humidité atmosphérique. Les aérogels en silice homogène monolithique de faible masse volumique présentent une capacité élevée d'isolation thermique, une résistance mécanique améliorée et une bonne transparence optique.

Abstract: In a dispenser (1), the actuation tappet (20) is guided with respect to the base element (2) with the outer circumference of an elastically deformable shaft section (32) essentially free of play to such an extent that, on actuation, this shaft section leaves the associated slider guide (43) and is then released for the purpose of deformation, in order, for example, to open an outlet valve (21). Both valve bodies (22, 23) of this valve (21) consist of elastic material. As a result, relatively flexible materials can be used, despite the high degree of functional reliability.

Abstract: To electrophoretically paint plate-like articles (W) the latter are conveyed on a horizontal conveyance path (D) through a cell (Z) containing a painting bath and at least one electrode. The anodic or cathodic connection to the travelling article (W) is made by means of an endlessly circulating contact drive (K) preferably formed by a metal strip and a contact device (Ko), situated outside the cell (Z), for supplying the anode current or cathode current to the contact drive (K). The paint deposited on the contact drive (K) in the cell (Z) is removed again by means of a cleaning device (R1, R2, R3, R4) situated outside the cell (Z), thereby ensuring a reliable connection to the workpiece (W). The novel device is suitable, in particular, for electrophoretically applying etching resists, plating resists and solder resists to printed circuit boards. <IMAGE>

Abstract: A self-propelled agricultural vehicle (1) has separate hydraulic motors (11,10) for driving the rear wheels (4) and front wheels (3). As the wheel load (F A ) decreases the danger of wheel slip occurs. According to the invention the hydraulic motors (11,10) are fed from the hydropump (9) such that as the weight load of the vehicle changes the torque applied to the wheels is altered. This is of particular importance in the case the vehicle is used as driving for an agricultural machine being supplied from a reservoir (6) on the vehicle.

Date Aug. 20, 1992.A method and a device designed to suck and to convey various types of liquids through a suction hose (45) and at the same time does (4) an additive to the liquid in an accurate proportion to the amount of the sucked liquid. A liquid or a liquid/air/gas mixture is sucked by means of a suction nozzle (2,45), which is influenced by a certain pressure P2 with a moderate suction action, and is passed through the suction hose (45). A dosage device (4), which includes a flexible dosage container (20), which is enclosed in a rigid casing (21), and which is influenced by a certain relatively lower pressure P3 (providing a stronger suction action) than the pressure in the suction hose (45), is connected directly to the suction hose (45). The pressure gradient P2-P3 is adjusted in such a way that no additive is introduced when only air/gas is sucked through the suction hose (45), whereas an additive does flow into the suction hose (45) as soon as some amount of liquid is sucked through the suction hose, and the amount of dosed additive is proportional to the amount of sucked liquid. The suction hose (45) may be connected to a separation and defoaming filter (3), which in its turn may be connected to a de-air receiver (5) with a mechanism designed to de-air the sucked liquid as well as to store the liquid without any admixture of gas/air.
