Title: Method for cutting workpieces with rotation symmetric planes, specially crankshafts, and device for using this method
IPC: B23B33/00
Filed: 1992-07-11
Abstract: The workpieces (3) are held between centres (7, 8) at both ends (10, 11) unmachined at the periphery. To machine the two workpiece ends (10, 11), the respectively opposite end is radially clamped. The radial clamping means (4, 6) are axially retracted at the workpiece end to be machined. Once this workpiece end is machined, it is clamped in a radially centring manner, while the centre (7, 8) is axially retracted. At the opposite, still unmachined end, the clamping means (4, 6) is axially retracted and the end is merely held by the centre (7, 8). Once this end is also machined, it is clamped in a radially centring manner, while the centre (7, 8) is axially retracted. During the machining of the centre area of the workpiece (3), both centres (7, 8) are thus axially retracted from the workpiece (3). The device for carrying out the method has two chucks (1, 2) which have radially and axially adjustable clamping elements (4, 5). One chuck (1) has clamping elements (4) clamping in a centring manner as well as clamping elements (5) clamping in a compensating manner. The clamping elements (4, 5) are radially adjustable independently of one another. Since the locating centre (7, 8) is retracted from the workpiece (3) in the area of the clamping elements (4) clamping in a centring manner, no constraint can occur between this locating centre (7, 8) and the clamping elements (4). The workpiece (3) and the device are consequently not loaded to an inadmissibly high degree. In addition, high true-running accuracy of the workpiece (3) is achieved.

Abstract: A process is described for forming, over a silicon surface, a titanium nitride barrier layer having a surface of (111) crystallographic orientation. The process comprises: depositing a first titanium layer (40) over a silicon surface (20); sputtering a titanium nitride layer (50) over the titanium layer (40); depositing a second titanium layer over the sputtered titanium nitride layer; and then annealing the structure in the presence of a nitrogen-bearing gas, and in the absence of an oxygen-bearing gas, to form the desired titanium nitride having a surface of (111) crystallographic orientation and a sufficient thickness to provide protection of the underlying silicon against spiking of the aluminum. When an aluminum layer (80) is subsequently formed over the (111) oriented titanium nitride surface, the aluminum will then assume the same (111) crystallographic orientation, resulting in an aluminum layer (80) having enhanced resistance to electromigration.

Abstract: To separate documents (14) having different degrees of rigidity from a stack, a separating roller (20) grips the top sheet of the stack in each case in a non-positive manner to push the said sheet against a slope (18) and to lift it from the stack on the said slope. The separating roller (20) is mounted so as to be freely movable in a plane parallel to the plane of the stack, so that it rolls a distance away from the slope (18) which depends on the rigidity of the document on the stack, until the front edge of the sheet can be deflected on the slope (18) for separating. The separating roller (20) is thereby automatically adjusted to the optimum distance from the slope (18) for the rigidity of the document in question. <IMAGE>

Abstract: In an arrangement for transforming an inward-conveyed multi-lane stream of containers into a single-lane stream of containers to be conveyed outward, an intermediate conveyor (3) is provided between the inward conveyor (2) for the multi-lane stream of containers and the outward conveyor (4) for the single-lane stream of containers, this intermediate conveyor consisting of a plurality of conveyor belts (7) driven at graduated speeds (speed graduations). In order to transform the multi-lane stream of containers, the intermediate conveyor (3) forms an alley which narrows in the direction (A) of transport symmetrically relative to a median axis (M) of the intermediate conveyor (3) in the manner of a funnel to a conveying width corresponding to the single-lane stream of containers which is to be conveyed outward. An exit region of the intermediate conveyor (3) is adjoined by the outward conveyor (4) which, at least at this exit region, is designed symmetrically relative to the median axis (M) and has a conveying width corresponding to the single-lane stream of containers. In the direction (A) of transport, the intermediate conveyor (3) has more than two speed graduations. Furthermore, speed graduations are also provided transversely to the direction (A) of transport. <IMAGE>

Abstract: The improved wellhead structure of the present invention includes a casing or tubing string (10) which is sealed to the housing (18) without the aid of elastomeric seals and an internal bushing (14) to assist in providing the tight gripping and sealing engagement between the string and the housing. The structure provides a substantial inner diameter which is unrestricted unless landing shoulder is included in the structure. Also, the internal bushing used with the cold forging of the string into the housing recess improves the gripping and sealing engagement therebetween. In one form the bushing (14) includes a series of external projections which alternate with the gripping and sealing projections within the housing recess and in another form includes a resilient annulus (42) between the interior of the bushing and the string to ensure the uniform application of pressure against the interior of the string. In still another form an internal landing shoulder is cold forged into tight engagement with the interior of the housing which allows full bore operations to be carried through the housing until the landing shoulder is to be installed. Also provided is a wellhead structure with a tieback structure in which the upper end of the casing is cold forged into the interior of a hanger while the casing is supported on slips.

Abstract: An antenna for portable wireless apparatus as shown in Figure 5 is capable of operating satisfactorily when an antenna element (8) is extended out of a case (7) or stowed in the case (7). A portion (8 a ) of the antenna element (8) not stowed in an antenna stowage pipe (12) when the antenna is pushed into the plastic case, functions as a radiation element. A portion of the antenna element and the antenna stowage (12) pipe produced of a metal for stowing this portion constitute an impedance stub circuit. Antenna impedances of the antenna element in the extended and stowage positions as well can be made approximately the same by properly setting the length of the antenna element which is stowed in the antenna stowage pipe and the length of the portion not stowed in the stowage pipe.

Abstract: The method and machine is shown for the production of rolls or logs of web material. The web material is fed through a nip (5) formed between two winding rollers (1, 3) and wound up around a core to form a roll or log (R) within a winding space defined by said two winding rollers and by a third roller. At the end of the winding of a log, the third roller (7) is temporarily accelerated to locally increase the speed of the web and to put the web material in tension between the third roller and one of said winding rollers. The tearing of the web material takes place because at that moment the incoming web is pinched between a new core and the one winding roller on which the material is driven out.

Abstract: Selon un procédé d'extraction du sucre, par exemple, contenu dans des boissons, par séparation à travers une membrane, on mesure le débit de préférence en amont et en aval de l'installation à membrane (2). La différence entre les débits ainsi détectés est déterminée par un dispositif d'optimisation de la qualité (18) et comparée avec une valeur optimale (Xopt) du point de vue de la qualité du produit. Tout écart éventuel est utilisé comme grandeur de guidage de la commande ou de la régulation de la pression dans le circuit de rétentat (8) de l'installation à membrane (2). Cette adaptation constante de la pression exercée sur la membrane permet de compenser de manière optimale la rétro-diffusion indésirable d'eau du côté du perméat vers le côté du rétentat de l'installation à membrane (2) et d'améliorer ainsi la qualité du produit.
