Abstract: The invention provides a method of manufacturing a twist drill having a cutting insert. The method includes the steps of providing a cutting insert which has a prismatic shape and which comprises a layer (16) of abrasive compact which is bonded to a cemented carbide backing (18). The insert has on a first facet (20) a cutting edge formed by the abrasive compact layer, and on a second facet (22) a seating surface formed predominantly by the cemented carbide backing. The first and second facets define a predetermined first angle with each other. A twist drill (24) is provided, having a seat (30) in its flank. The seat defines a support surface (32) adapted to receive a seating surface of the insert, and is inclined at a predetermined second angle to the face (26) of the drill. The insert is bonded into the seat, so that the cutting edge of the insert defines the major cutting edge of the drill and the first facet of the insert coincides with the face of the drill. The invention includes cutting inserts and twist drills produced by the method.

Abstract: Bande transporteuse sans fin (5) comportant une partie inférieure (6) dotée, sur sa surface inférieure, d'une nervure centrale (7). La surface inférieure de la nervure comporte une gorge (10) destinée à recevoir un câble porteur (11), au moins le long de la majeure partie de l'étendue du transport des marchandises, de ladite bande transporteuse. Cette dernière comprend également une pluralité de poulies (12) disposées sous le câble porteur et adaptées pour directement supporter celui-ci, ainsi que des galets de guidage (14, 15) agencés au moins le long de l'étendue du transport des marchandises, et entrant en contact avec les surfaces latérales de la nervure (7). La largeur et la profondeur de la gorge sont telles que les galets de guidage peuvent transmettre des forces latérales au câble porteur (11). De plus, les galets de guidage établissent un tel contact avec les surfaces latérales de la nervure, que celle-ci est sensiblement immobile dans la direction verticale. Enfin, la bande transporteuse est dotée de moyens de guidage (18, 19) le long de l'étendue du transport des marchandises, entrant en contact avec la bande afin de l'empêcher de basculer du câble porteur. Cette conception permet d'entraîner la bande à vitesse élevée et sur des courbes prononcées.

Abstract: A self-locking screw with a partial deformation of thread pitches, at least one thread pitch having an interrupting displacement of one flank or the edge line with respect to the helix line of the thread. The technical problem is the provision of a self-locking screw which can be screwed into a female thread without deformation thereof and which ensures considerable resistance against turning backwards. Two adjacent thread pitches have a displacement of the flanks (10, 11), which displacements are in the opposite sense and increase linearly, the distance between the edge lines (8) increasing in the opposite sense to the screw-in direction. <IMAGE>

Abstract: The running speed of said vehicle, in particular a heavy goods vehicle combination, is predetermined by the power setting of an internal combustion engine or the like. In said process, the volumetric flow of hydraulic liquid required for the relevant set of driving wheels is calculated as a function of the corresponding travelling speed and applied to the set of driving wheels, whereby the speed of said set of driving wheels corresponds with the respective travelling speed or is lesser or greater than the latter by a predetermined value. Preferably, the speed of the set of driving wheels is about 10% greater than the corresponding travelling speed. Thus a particularly favourable traction is achieved without excessive wear of the tyres. If necessary, the steering angle of the individual sets of wheels can also be taken into account for calculating the flow quantities required for said sets of wheels.

Abstract: The invention relates to apparatus for economically washing moving webs, in particular in washing processes for the solution wash or the like, in which in a common vapour-tight housing which is sealed except for an inlet and an outlet opening for the moving web there are arranged a plurality of treatment units for the moving web through which the moving web passes via upper and lower rows of deflecting rolls in essentially perpendicular loops, and achieves a water-saving in such apparatus in particular through improved guidance of the wash liquor during the treatment. According to the invention it is proposed to this end that the feeding of the treatment liquor, which runs off the web in every treatment compartment and is collected, to the distributor pipes be effected by recycling the treatment liquor back into the same treatment compartment, while the feeding of the treatment liquor to the flat jet nozzles be effected by returning the treatment liquor into the upstream treatment compartment (Fig.). <IMAGE>

Abstract: The advantages of high alumina cement (early strength, resistance to sulphate attack) are preserved and its disadvantage (weakens with age) is solved by mixing it 50:50 with silica fume, gasifier slag, fly ash or other pozzolanic or latently hydraulic material. This encourages formation of gehlenite octahydrate in preference to the harmful 'conversion' (weakening) reaction.

Abstract: A method for forming a connection between two levels in a semiconductor structure includes first forming a VIA (14) through an insulating layer (12) to an underlying structure (10). Sidewall spacers (22) and (24) are formed on the vertical walls of the VIA (14). The spacers (22) and (24) have tapered surfaces. A barrier layer (30) is then formed over the bottom surface of the VIA followed by CVD deposition of a conductive layer (32) of WSi₂ to provide a conformal conductive layer. An aluminium layer (38) is then deposited by physical vapor deposition techniques with the descending portions of layer (32) providing a conductive connection between the aluminum layer (38) and the lower structure (10) in the VIA (14).

Abstract: A force sensor 1 suitable for use in a weighing device comprises a generally parallelepiped-shaped block 2. There is at least one transverse hole 6 in the block defining a fixed vertical column and a mobile vertical column. Upper and lower horizontal beams 7 and 8 also defined by the hole couple the fixed and mobile vertical columns and define with them a vertical first deformable parallelogram. Deformation sensors are fixed to at least one pair of reduced cross-section areas on one such horizontal beam. The fixed vertical column is rigidly fixed to a base. A receiver plate is coupled by a damper system 5 to the mobile vertical column. This damper system includes a vertical frame forming a second deformable parallelogram elastically deformable in a vertical plane. It is less stiff than the first deformable parallelogram and incorporates two vertical sides 13 and 27 respectively fixed to the mobile vertical column and to the receiver plate and two substantially horizontal blade members 23 coupling these vertical sides. The vertical side coupled to the receiver plate is mobile without any direct contact with the block and comprises two vertically mobile crossmembers 27 on each side of the block; the blade members have a shorter side connected to the mobile column and a larger side connected to the crossmembers.

Abstract: Pellicule en sulfure de polyphénylène à orientation biaxiale et à excellente capacité de déposition, son procédé de production et procédé d'exposition de la pellicule à une déposition sous vide. Une pellicule en sulfure de polyphénylène à orientation biaxiale présente une élongation longitudinale pouvant aller jusqu'à 0,4 % lorsqu'elle est chauffée de 25 à 70°C à une vitesse de 10°C/min. sous une tension de 3 kg par mm2 de la superficie de la section transversale de la pellicule. Par conséquent, lorsque l'on soumet la pellicule à une déposition métallique sous vide dans un appareil de déposition sous vide à enroulement, la pellicule ne se ride guère lorsque la tension longitudinale moyenne appliquée sur la pellicule sur une bobine de refroidissement de l'appareil de déposition sous vide est fixée entre 0,5 et 3 kg par mm2 de la pellicule. On supprime ainsi le phénomène de fixation des rides par la chaleur latente du métal évaporé qui produit des rides sur la pellicule métallisée et provoque une détérioration des propriétés de sa surface (dommages thermiques).

The pulley consists of two disklike sheaves which are variably pressed together. To reduce power losses, bearings for the sheaves assure that the sheaves are either non-loaded or not loaded parallel, but rather are variably inclined to each other. Then, the groove between the sheaves is at its maximum width approximately at the points where the belt leaves the driving pulley and comes onto the driven pulley.
