Abstract: A heat exchanger comprising a plurality of plates (5, 6) arranged adjacent to each other, whereby passages (9, 10) for two mutually heat exchanging fluids are formed between the plates. The plates comprises corrugations or ridges (7, 8), whereby the corrugations form an angle (a) with the longitudinal rim of the plate. In the first type of plates the corrugations form a first angle (α<sub>1</sub>) with said rim and in the second type of plates the corrugations form a second angle (a<sub>2</sub>) with the rim. The plates are combined in order to form two types of passages having different thermal length. The firsttype of passage (9) is obtained by combining a first plate and a second plate and the second type (10) of passage is formed by combining a first plate and a second plate, wherein one of the plates is turned 180° in its own plane. Thus, two types of passages having different thermal lengths are obtained. The two types of passages can be combined for each heat exchanging fluid in order to provide the desired thermal length for that fluid.

Abstract: A length measuring system for measuring or adjusting the relative position of two objects includes a housing for a scale. This housing is fastened to a mounting surface of one object by means of at least one clamping shoe which engages a groove in a side surface of the housing. The inside surface of the groove adjacent to the mounting surface encloses with the mounting surface an angle  alpha  measured in a plane perpendicular to the lengthwise extent of the housing. The clamping shoe abuts by means of appropriately situated projections the mounting surface, the side surface of the housing, and the inside surface of the groove. Thus, the mounting shoe applies a rotational torque to the housing. This torque is about an axis of rotation running the longitudinal extent of the housing. In this way, a whole surface engagement of the support surface of the housing against the mounting surface is provided, despite the fact that the clamping shoes are positioned on only one side of the housing.

Abstract: The copper wires employed for electrical resistance seam welding of tinned sheet metal with the help of wire electrodes until now had to be taken back to the smelter as old metal after a few applications. The additional operating costs associated with this were until now unavoidable for long seam resistance welding of tinned sheet metal since multiple uses or applications of the copper wire for resistance seam welding have proven to be impossible in spite of years of research. The problem of these additional operating costs can be solved such that new copper wires with a reduced diameter can be directly drawn from the copper wire employed as wire electrodes for resistance seam welding after their use in welding. These wires then, for example, can be used as signal conductors or as windings. The properties of these wires are totally in accord with copper wires that are directly drawn from new copper. By this process, the additional operating costs mentioned above are substantially reduced and in many cases are even totally eliminated.

Abstract: An arrangement for the generation of CO2 laser pulses of high power. In a first step, the laser medium is brought by an electrical pumping pulse into a state of extremely high population inversion and, in a second step, this inversion is decayed suddenly by a Q-switching effect in such a manner, that radiation pulses of extreme power magnification arise. The power is supplied to the laser-gas discharge by a power-supply unit which permits the pulsed supply of pumping energy. The associated laser resonator is formed from a first resonator mirror with a fixed reflectivity R1, frequency-selective element, a special, highly angle-selective gas discharge tube, and a special component material transparent to the laser radiation that functions as a second resonator mirror with a variable reflectivity R2. The second unit is comprised of a modulator with a high cutoff frequency in the form of a Fabry-Perot interferometer arrangement with a rapidly changeable optical wavelength.

Abstract: To obtain a waterproof transition between the roofing frame of a rooflight and the roof, lead aprons are used. For this, the material is unwound downwards from relatively large rolls, starting from the frame, and is then stretched in order to match it to the shape of the roof tiles. For this purpose, the material is pressed clean into the recess of the tiles by means of a fold, and often cracks, through which water can penetrate, occur in the lead apron. Since the lead apron is exposed directly to the weather, the lead disintegrates over the years, and therefore a greater thickness than is actually necessary has to be chosen at the outset. In addition, a disintegrated lead apron has an unpleasant appearance and is seen as a foreign body on the roof. The new roofing frame for windows, doors or the like is to be designed in such a way that the danger of cracks in the lead apron is reduced and a permanent decorative appearance becomes possible, whilst at the same time preventing lead secretions as a result of weathering. A further object is to prevent harmful lead secretions as a result of weathering and consequently to improve environmental protection in roof coverings, facades and auxiliary materials for sealing transitions in roof, wall and corner connections. The roofing frame of rooflights, doors or the like consists of a ridge, a breastplate, two flashings and a lead apron which is covered with at least one aluminium layer. Roofing frames of rooflights, doors or the like and lead strips of any kind for roof coverings, facade claddings or auxiliary materials for roofs and walls. <IMAGE>

The trough has an arcuate cross section and is inclined so as to slope downwards towards its discharge end. The upper end of the trough is connected to a motor which is capable of rotating the trough back-and-forth on its longitudinal axis. In operation, the trough is rotated back-and-forth and the bulk material is introduced into the trough at the upper end thereof. Due to the inclination and back-and-forth movement of the trough, the particles of the bulk material travel towards the discharge end of the trough along zigzag paths thereby allowing the trough to be shortened. The back-and-forth movement of the trough also causes the particles to bump into one another and push each other aside during the course of travel so that effective singularization is achieved.
