IPC: B65G25/02
Filed: 1987-08-13
Abstract: A guide rail (12) for the positive transport of workpiece carriers (20) carrying workpieces (18) is situated below the work units (14) of a machining apparatus (10). The guide rail (12) is traversed at its bottom by a transport rail (34) comprising drivers at the same intervals which engage from below into the workpiece carriers (20). A drive device moves the transport rail (34) in the longitudinal direction of the guide rail (12) and takes along all the workpiece carriers (20) on the guide rail (12). The transport rail (34) is then lowered, moved back along a bypass without influencing the workpiece carriers (20) and then moved upwards again in order to couple the drivers of the transport rail (34) with the workpiece carriers (20) again. Clamping devices (62) secure the workpiece carriers (20) during the machining of the workpieces (18).

Abstract: The invention relates to an assembly comprising an auxiliary chassis (1), which can be detachably bolted to the body of a motor vehicle, and pivotally mounted suspension arms (2), each fitted to the auxiliary chassis in two spaced hinged bearings (3, 4), one each of these two hinged bearings containing two at least approximately horizontal bearing cheeks designed to accommodate a rubber-metal bearing fixed on the suspension arm, through the inner sleeve of which bearing a roughly vertical bearing bolt (31) can be introduced, which at the same time also serves to fix the auxiliary chassis onto the vehicle body. The bearing cheeks carry opposing axial bearing extensions with a semi-circular contour, the ends of whose inner sleeves are enclosed in a collar-shaped manner over part of their circumference. The laterally open area of the axial bearing extension is designed in each case in such a way that the suspension arm can be fixed on the auxiliary chassis only in such a way that it is first inserted with the inner sleeve of the rubber-metal bearing into the bearing extension through the laterally open areas and bolted into the second hinged bearing only after swivelling round the bearing extension. <IMAGE>

Abstract: The filtration performance of a slurry containing crystallized wax, dewaxed oil and dewaxing solvent is improved by use of an agitator means which possesses a characteristic dimension which when divided by the average wax crystal diameter yields a dimension­less number of about 1,500 or less, preferably about 1,000 or less, more preferably about 500 or less, most preferably about 250 or less. Use of an agitator means which possesses a characteristic dimension yielding a dimensionless number in the range recited above causes a reduction in the size of the vortex generated as the agitator means passes through the slurry during chilling. As a consequence, more intimate contacting of the wax particles during chilling is promoted. 
     The needed characteristic dimension of the agitator may be obtained in any number of equally acceptable ways. Single large agitator blades can be replaced by more numerous smaller blades; large blades can be perforated, notched, etc. 
     Any alteration which causes the agitator cha­racteristic dimension to be reduced so that when it is divided by the average crystal wax size the resulting dimensionless number is about 1,500 or less is an acceptable modification.

Abstract: Circuit permettant d'utiliser un moteur synchrone multiphase (10) sur un réseau c.c., dans lequel des redresseurs de courant (15-18) sont reliés en série avec les sections d'enroulement (w1-w4) de l'enroulement de l'induit (12) du moteur (10), lesdits redresseurs étant excités l'un après l'autre par un compteur annulaire (38). Un bloc de commutation du compteur annulaire (19) fait avancer pas à pas le compteur annulaire (38), en effectuant une comparaison entre les deux tensions qui décroissent au niveau des redresseurs de courant fermés (15-18). De plus, pour réduire la région d'auto-commande du moteur à une région angulaire qui est essentiellement inférieure à une demi-période électrique, la valeur des deux tensions de comparaison, qui décroît avec le temps, est comparée par le bloc de commutation du compteur annulaire (19) avec une valeur prédéterminée (k.Us) et l'avance pas à pas du compteur annulaire est ensuite déclenchée seulement lorsque cette tension dépasse la valeur prédéterminée.

Abstract: On décrit l'utilisation de matériaux en céramique oxydée pour les outils de presse destinés au formage d'éléments en verre ou en céramique contenant du verre ayant une excellente finition de surface et des tolérances serrées. Il s'agit de matériaux polycristallins, à phase simple ou multiple, inertes au contact avec les composants optiques à presser et qui sont caractérisés également par des propriétés mécaniques et thermiques sensiblement supérieures à celles des substances monocristallines, dont le comportement est essentiellement anisotrope en raison de leur anisotropie géométrique. Le matériau prévu pour l'application envisagée par l'invention peut être constitué d'une céramique Al2O3 ou une céramique contenant du ZrO2 et/ou HfO2. Le matériau peut également être réalisé comme matériau multiphase, c'est-à-dire qu'il peut contenir un constituant matriciel et au moins un constituant particulaire dispersé de manière discrète dans ladite matrice. On envisage de préférence les céramiques contenant du ZrO2, ZTC, PSZ ou TZP, qui possèdent des caractéristiques thermomécaniques remarquables pour les applications envisagées par l'invention, en raison de la chimie et surtout de la cristallographie de leurs constituants. A cette fin, des mécanismes comme par exemple le "renforcement de transformation dû aux contraintes" et le "renforcement au niveau des microfissures" jouent un rôle important. L'emploi des matériaux intéressés permet de réaliser des outils de presse pour le formage, sans travaux de reprise, d'éléments optiques ayant des surfaces planes et/ou sphériques et/ asphériques convexes et/ concaves, dotés d'une finition superficielle de grande qualité et d'une grande précision dimensionnelle; en même temps on obtient des améliorations des processus de fabrication.

Abstract: In electrical apparatuses of high-voltage direct current (HVDC) transmission systems, AC and DC voltage fields occur simultaneously alongside one another. In apparatuses of such systems the use of different materials as insulating materials to form insulating paths is unavoidable at some points. In consequence, heavily distorted electrical fields are produced from time to time because of the different characteristics of the dielectric constants and the specific resistances. According to the invention, to match the DC voltage field to the AC voltage field, solid material barriers (12 to 17) of pressboard are constructed, having an electrical conductivity increased in a graduated manner with respect to conventional pressboard, the specific resistance of the pressboard having the highest electrical conductivity being only approximately 2 to 10 times greater than that of the transformer oil, and the pressboard barriers (12, 13) having the highest electrical conductivity in each case being arranged at the end of the insulating path at which the field lines have the smaller radii of curvature. The high-voltage insulation arrangement according to the invention is advantageously suitable for the insulation of the inner end of high-voltage ducts and for the insulation of the high-voltage winding of transformers and inductances for HVDC transmission. <IMAGE>

Abstract: The dental pin (1) has a rod whose apical part (1a) is cylindrical and is followed by a truncated neck part (1b) continued by a head (1c) adjacent to the truncated part (1b). The head (1c) is used for the restoration, in composite or in amalgam, of a stump intended to receive a dental crown. The head (1c) is of a non-circular cross-section, which corresponds better to the shape of a natural tooth than if it was of circular shape, but requires that it should be possible to orient the pin when it is in position in the root canal, after endodontic preparation of the latter, as a function of the dental arch. Consequently, the rod (1a - 1b) is entirely smooth. The apical part (1a) is highly retentive, while the neck part (1b) provides a strong base for the restoration of the stump, bearing firmly on the natural crown. <IMAGE>

Abstract: The fibre-baling press comprises a stable machine frame having a press ram which is mostly displaceable from the top downwards and under which a press box can be displaced. The press box comprises a press-box casing (2) which should be closed all around. It stands on a press-box base, which in this case simultaneously forms the lower press plate (1) for the pressing operation. Both the press ram and, in particular, the press-box base should be designed in the manner of a trough according to the invention in order to give the piece of packaging material for the upper and lower side of the bale a pre- orientation towards the bale after the press-box casing is removed from the bale. It is a particular advantage if the trough-like opening cross-section of the base plate (1) is greater than the cross-section of the press-box casing (2) in order to prevent the compressed material from swelling up over the four side flanges (6') of the trough after the press-box casing has been removed. The plastic sheeting should be aligned parallel to the bale. …<IMAGE>…
