Abstract: A process and apparatus for producing a non-woven, especially a non-woven electret, fiber sheet provides for directing the non-woven fibers at a collecting surface and into an electric field between at least one electrode and the collecting surface. 
     This process, in which the fibers are collected in the electric field, enables economical production of a non-woven electret fiber sheet of a single layer structure having a large amount of polarized charges (giving a total electric charge per unit area of at least 7 x 10- 11  Coulomb/cm 2 ), and a weight per unit area of at least 60 g/m 2 , preferably greater than 80 g /m 2 .   
     The non-woven electret sheet may have the large amount of electret charge throughout its thickness and/or a uniform weight distribution and thus have excellent dust collecting properties.

Abstract: The invention relates to a method and an arrangement for carrying out the method for automatically measuring direct currents or physical quantities which are attributable to these, particularly for tasks of measuring over a large number of decades with uniformly high accuracy and/or without loading the measuring circuit. A direct current (2) to be measured is compensated by a reference current (3) of the opposite direction in accordance with the principle of progressive approximation at a point of compensation (1) which is monitored by a comparator (4). The reference current (3) is generated by a combination of compensation elements (5) consisting of digitally switchable reference resistors (9) and a digitally controllable reference voltage source (10). The evaluation of the comparator output, the control of the compensation elements (5), the determination of the current (2) to be measured and the outputting of the measurement value are effected in an evaluating and control device (6) which is implemented by means of a microprocessor. <IMAGE>

Abstract: A process for soldering SMD components temporarily held by a solder head evacuated by means of a vacuum connection. During soldering or desoldering SMD components (13), the body of these components is temporarily covered by the solder head (1), as a result of which, cooling, e.g. by lateral blasting from the outside, is not very efficient. The invention provides for the components to be temporarily held on the solder head (1) by a vacuum device, which is connected to the solder head (1) via the vacuum line (15), and to be cooled after completion of the soldering process by switching off the vacuum and at the same time blasting cooling gas into the vacuum line (15) and hence on to the body of the component (13). For normal SMD components (13), this cooling lasts for approximately 10 seconds and prevents damaging re-heating of the components (13).

Abstract: In a thyratron gas discharge device, magnetic material 5 is located coaxially with the anode 2 to produce a magnetic field between the anode 2 and cathode 3 which is substantially parallel to a discharge established between them. This causes electrons emitted from the cathode 3 to have longer path lengths than would otherwise be the case and so the ionisation density within the device is increased. This improves the operating characteristics of the thyratron and results in greater utilisation of the cathode 3.
