Abstract: A polyhedral tool for producing an orthodontic appliance has a main body with one upper and one lower surface that are parallel to each other and at least one other pair of nonparallel, opposite lateral surfaces. One of the two nonparallel surfaces of the body extends at an angle of 5°-45° and the other at angle of 45°-85° to the upper and lower surfaces of the body. Each of the nonparallel lateral surfaces is formed with a dovetail groove. Respective thin plates each have a dovetail tongue fittable into a respective one of the grooves.

Abstract: A strand guide for a cast strand has a first roller bridge to one wide side of the cast strand and having ends defining two first section corners, a first fixed support adjacent the first roller bridge, a second roller bridge to the opposite wide side of the cast strand and having ends defining two second section corners, and a second fixed support adjacent the second roller bridge. Respective rows of rollers are rotatably mounted on each of the first and second roller bridges for engaging the respective wide sides and thereby supporting and guiding the cast strand. Respective first and second hydraulic positioners connect the first and second corners of the first and second roller bridges to the first and second fixed supports for individual positioning the rollers of the first and second roller bridges symmetrically or asymmetrically relative to the neutral phase of the cast strand.

Abstract: A method of making a hinge has the steps of forming a region of a piece of sheet metal with a groove and then bending the piece of sheet metal to form the region into an eye with the groove opening inwardly into the eye so that the piece of sheet metal with the eye forms a first leaf. A pivot pin with a radially outwardly projecting thickened region is fitted and pressed into the eye such that the radially thickened region radially elastically widens the eye. Once the thickened region reaches the groove, the eye springs back so that the pivot pin is then captured held in the eye.

Abstract: The invention relates to a method for the topographical presentation of structural alterations in an examined brain using volume data records. In line with the invention, this method is distinguished in that functional areas are mapped by extracting profiles, where the profiles record boundaries for two functional areas in the examined brain, in that the boundaries of the two functional areas are recorded by calculating a multivariant distance measurement, and in that a microstructure in the region of the boundaries of the two cortical areas is recorded and is compared with at least one microstructure in a boundary region of a reference brain. To increase the comparability of various areas in various brains taking into account the interindividual variability, it is expedient for the volume data records to be transformed to a target volume data record using an elastic registration method.

Electrically nonconductive spring-loaded elements are provided between the anode and the interconnector for permitting relative movement therebetween.

Abstract: A bag-puckering system has a pairs of grippers engageable with upper corners of respective bags. The grippers of each pair are shiftable between an inner position in which the respective bag is puckered open and an outer position in which the respective bag is held flat. The pairs of grippers are aligned in a longitudinal row and shiftable in a travel direction through a filling station wherein fluent material can be poured into the bags. A controller upstream of the filling station measures a length in the direction of the bags and generates respective outputs corresponding thereto. A movable cam at the filling station operatively engages the grippers in the filling station for shifting the grippers between their inner and outer positions. A drive connected to the control means and to the cam can shift the grippers in accordance with the size of the respective bags.

Abstract: The invention relates to a method of pressing pressing-material mats during the production of wood-material panels in a continuous press, wherein the continuous press has upper and lower heating plates, upper and lower entry plates, which project on the entry side and form an entry mouth, and, in the upper and lower parts of the press, endlessly circulating steel pressing belts which, with the interposition of rolling bars, are supported on the entry plates and the heating plates, wherein the height h0 of the entry gap and, possibly, the entry contour of the entry mouth are set, and wherein a pressing-material mat, which is produced, and possibly pretreated, in a spreading station arranged upstream of the press, is introduced into the continuous press and pressed therein. This method is characterized in that the entry-gap height is checked, set and/or regulated in dependence on the density and/or the weight per unit area of the pressing-material mat.

Abstract: A latch has a housing and a dead bolt shiftable on the housing between extended and retracted positions. A latch nut is rotatable on the housing and connectable to door handles and carries actuating and panic levers. An actuating element is connected between the dead bolt and the actuating lever, and a panic element is connected between the panic lever and a locking pawl and is movable between an unactuated position and an actuated position to shift the locking pawl into an unlocked position. A key cylinder on the housing has a movable actuating lug movable between a locking end positing and a freeing end position. A pivotal locking pawl is shiftable by movement the actuating lug of the key cylinder into a locked position blocking movement of the actuating element and holding the dead bolt in the extended position and an unlocked position freeing the bolt and actuating element.

Abstract: An apparatus for winding a flexible web continuously moving in a longitudinal travel direction as rolls onto sleeves has a winding station for holding a sleeve and rotating it about an axis for winding the web onto the sleeve. Upstream of the winding station at a changeover station a fresh sleeve is held adjacent the continuously moving web. A shell juxtaposed with the fresh sleeve in the changeover station forms therewith a gap. A cross-cutter for the web is provided adjacent an end of the gap and can form on the web a trailing end and a leading end so that the trailing end travels to the winding station for winding on the sleeve therein. Air is drawn air into the end of the gap to aspirate the leading end into the gap. This leading end is electrostatically adhered to the fresh sleeve in the changeover station.

Abstract: The invention relates to a method and a blank for producing a screw-tube conveyor in the form of a cylindrical rotary tube (110) with an internal screw spiral (120) for conveying and mixing a bulk material. To simplify the method and to create even long screw-tube conveyors with small diameters in an relation to their length, it is proposed according to the invention first to produce a one-piece blank, which comprises a base portion in the basic form of a parallelogram and having laterally mounted fins. In a second method step, the fins are then bent, preferably by 90°, with respect to the base portion. In a third method step, the base portion (112) is then bent along bending lines (115i) in such a way that the base portion forms a helical casing portion (111) of the rotary tube (110) and the previously bent-round fins (122) form segments of the screw spiral (120) arranged inside the rotary tube (110). The invention also relates to a screw-tube conveyor produced in this way.
