Abstract: The present invention relates to a method and device for the contactless measurement of the wear and deformation of railway tracks. In this case, the rail head is illuminated by generating a streak of light (5), and moved along a prescribed measuring distance. The scanning of the streak of light (5) is performed using video technology along this prescribed measuring distance. The actual rail profile is determined by comparing the scanned signals with a prescribed characteristic. This method is carried out using an illuminating unit (4), which is connected in a stationary manner to a rail vehicle (1), for illuminating the rail head in the form of a streak of light (5). The scanning of the streak of light (5) is performed via a video camera (6) rigidly connected to the rail vehicle (1). A computer (9) -aided evaluation unit (10) determines the actual rail profile from the image-displacement signals detected by the video camera (6). <IMAGE>

Abstract: The invention relates to a device for scraping material from a mass of that material, for example from a more or less cohesive heap of that material, for instance the removal of animal feed from a pit, comprising: 
a number of elongate members that are rigid due to tensile stress, such as pins, rods, strips or ropes. 
guiding means for guiding these elongate members in a selected, closed path having at least one active straight part, whereby these members substantially extend transversely of this path, and 
transporting means for conveying the elongate mem­bers along the path. 
     The invention has for its object to embody a device of the type known therefrom such that in the course of scrap­ing no accumulation of scraped-off material can take place, which also prevents stoppages of the device caused by such. In view thereof the device is characterized in that the closed path of the elongate members extends at an interval outside the path of the transporting means, at least in the area of the active straight part, such that scraped-off material can be discharged freely.

Abstract: Le composant d'exposition (10) d'un système de photogravure pour une tranche à semi-conducteur (28) comprend un laser (12) qui émet une lumière cohérente à travers une lentille d'expansion (14) puis à travers une lentille de contraction (16), de façon à acheminer un faisceau lumineux sphériquement convergent à travers un hologramme à transformation de Fourier sans lentille (22) et sur la tranche à semi-conducteur (28). La tranche (28) est disposée tangente à une hémisphère centrée sur l'hologramme (22), dont le point focal (26) du faisceau sphérique convergent est situé au milieu de sa surface incurvée. On forme ainsi une version réduite de l'image source à partir de laquelle l'hologramme (22) a été formé et on obtient des grandeurs caractéristiques sensiblement inférieures à celles pouvant être obtenues avec des systèmes du type à masque traditionnels utilisant une lumière de même longueur d'ondes.

Abstract: L'invention concerne une réaction de chaîne polymérase (PCR) basée sur une méthode de mise en séquence appelée amplification génomique avec mise en séquence directe (GAWTS) qui évite le subclonage et permet au moins de quintupler la vitesse d'acquisition de séquences. Le procédé implique la fixation d'un promoteur de phages sur au moins l'un des agents d'amorçage de la réaction de chaîne polymérase (PCR). Les segments amplifiés par PCR sont transcrits pour augmenter encore le signal et pour produire une abondance d'un gabarit monobrin pour la mise en séquence didésoxy induite par une transcriptase d'inversion. Un agent d'amorçage d'une transcriptase d'inversion à terminaison marquée complémentaire de la séquence désirée génère la spécificité additionnelle requise pour produire des données de séquence non ambiguës.

Abstract: The invention relates to a process for the production of directionally solidified or crystallised castings with at least one sensor for recording temperatures in metal or alloy melts in a casting mould, with a thermocouple (41) provided with a heat-resistant sheath surrounding the thermocouple, the thermocouple being introduced into the melt. The position of the phase boundary between the liquidus and the solidus is then determined from the measured temperatures by interpolation and the withdrawal rate of the casting is controlled in such a way that the phase boundary during the withdrawal of the casting remains at all times in the desired region of the insulation (10), somewhat above the cooling head (14). For this purpose, it is advantageous if the heating temperature for heating the casting mould is stored as a parameter in a computer against the travel or the particular position of the casting mould in the vacuum furnace (T C DEG f (travel of the casting mould)). This heating-temperature profile as a function of the particular position of the casting mould in the vacuum furnace in conjunction with the withdrawal rate from the casting mould is then available in conjunction with the withdrawal-rate profile as a reproducible variable for subsequent casting operations. <IMAGE>

Abstract: A fixing of a beadless end section of an elastomeric hose which can be loaded in tension having at least one embedded strength-bearing layer of cord threads, to a fitting consisting of metal or plastic is implemented by clamping the wall of the end section in between the fitting and a separate concentric clamping piece. In order to be able to transmit higher tensile forces with such a fixing, without any risk of the bellows wall pulling out from the clamp between the fitting and the clamping piece, the clamp of the end section (12) has two clamping zones (21, 22) located one behind the other. In the first clamping zone (21), the wall of the hose (13) is compressed by at least 30% to, at the most, the total thickness of the strength-bearing layer (16, 17). In the second clamping zone (22) the hose wall is compressed only slightly. The length of the second clamping zone (22) is dimensioned such that the shear force which can be transmitted by the adhesion of the threads and elastomer is at least equal to the tensile strength of the threads. <IMAGE>

Abstract: In a method for forming a known arsenic doping in silicon substrates, an arsenosilicate glass layer deposited by ozone-activated thermal decomposition from the gas phase (CVD process) is used as diffusion source. The starting substances used for the decomposition are either oxygen-containing organoelemental silicon and arsenic compounds or suitable silicon-arsenic compounds. The AsSG layer is deposited at a temperature of between 380 and 440 DEG C and at a pressure between 10<3> and 10<5> Pa, then the arsenic is driven into the substrate from the AsSG layer by heat treatment and, finally, the AsSG layer is removed. The method is used in the production of trench-type capacitor storage cells (DRAMs) to achieve known substrate doping with a steep doping profile and its distinguishing features include a more beneficial temperature schedule and an improved substrate wafer throughput. <IMAGE>
