Abstract: Inductance variable dont la pression du curseur sur le conducteur du bobinage diminue lorsque le curseur est en déplacement rapide. L'inductance comporte: un conducteur (1) bobiné selon une hélice circulaire, un axe mécanique de rotation (2) disposé selon l'axe géométrique (XX) de l'hélice et un curseur (3) monté de manière à rester en contact glissant avec le conducteur et à coulisser uniquement longitudinalement de long de l'axe mécanique, afin que son contact sur le conducteur se déplace selon l'hélice lors d'un mouvement de rotation de l'axe mécanique. Pour réduire les frottements, et donc l'usure, lors d'un mouvement de rotation rapide de l'axe mécanique, un dispositif d'écartement (8) est associé au curseur (3) et tend, sous l'effet de la force centrifuge, à réduire la pression du curseur (3) sur le conducteur (1). Application, en particulier, aux inductances variables pour émetteurs de moyenne puissance.

Abstract: The high voltage testing system contains a series resonant circuit connected to a voltage source with a continuously variable frequency, whereby the insulation, connected in series with the inductor, which is being tested, either exclusively or at least partly, forms a part of the capacitance. The inductance may consist of several high voltage inductors constructed of modular elements. It is advantageous to use bar-core chokes. Preferably, the bar-core choke is suspended in the mass center by means of a mounting plate. Suitably, the coil of the inductor consists of two windings, each having a trapezoidal cross section. A static frequency converter would be suitable as a voltage source with variable frequency; the converter could be a direct converter built to act as an oscillating circuit converter, operating within the resonance frequency and with pulse-width control. At least one high-voltage capacitor may be connected in parallel to the insulation for the adjustment of the desired frequency. The advantage of this testing system for the testing of an insulation lies in the fact that this system permits testing with frequencies which are lower or higher than the line frequency. The testing system is small and very light-weight and contains elements which are more economical than was heretofore known.

Abstract: Heat exchanger for gases for use for room ventilation. The heat exchange between supply air and exhaust air is carried out by division of the supply air flow and of the exhaust air flow into a number of part flows which are guided past common partitions (16a) in neighbouring cells (16). This results in a considerable increase in the exchange area. The total path of the air flows is in this connection e.g. as follows: the external supply air flows from the upper half of the supply air cross-section via the cells 1, 3, 5, 7 etc. into the lower half of the exhaust air cross-section, the exhaust air flows in the opposite direction from the upper half of the exhaust air cross-section through the cells 2, 4, 6, 8 etc. via the lower half of the supply air cross-section to the outside (Fig. 1). <IMAGE>

Abstract: This invention relates to a process for the production of non-cellular polyurethane ureas elastomers using a chain-extender mixture produced from asymmetrically alkyl-substituted anilines by condensation with formaldehyde. The chain-extending agents used in the instant invention show medium reactivity to compounds containing isocyanate groups. These chain-extending agents may be processed both in high-pressure and in low-pressure metering and mixing units because they are either liquid at room temperature or can be melted at relatively low temperatures (below 55 DEG  C.). The homogeneous, i.e. non-cellular, polyurethane urea elastomers obtained in the instant invention are distinguished by having excellent mechanical properties.

Abstract: An apparatus for packaging articles, in particular fibre material compressed to bales, in heat sealable sheet material comprises a mandrel case (1) for a row of articles to be packaged and a transport means (3) to move these articles stepwise to the discharge end of the mandrel (1). Further the apparatus includes means (4,5,8 and 9) to feed at least one web of sheet material to the mandrel case (1) and to fold this web tube-shaped about the mandrel case. Longitudinal sealing jaws (12) and transverse sealing jaws (17,18) are mounted next to and in front of the mandrel case (1) respectively to weld together overlapping longitudinal edges and transverse edges of the tube of sheet material. A receptacle (14) comprising clamping members (24) is mounted adjacent the discharge end of the mandrel case (1 ). This receptacle may be moved between a transverse position, a pulling through position and a welding position. The mandrel case (1) takes care that before the transverse sealing jaws (17,18) move to each other first the tube of sheet material is pulled forwards along a sufficient distance to be able to form the transverse end wall of the package. Besides the mandrel case 1 avoids expansion of the material to be packaged before it is completely closed in the package.
