Abstract: This invention provides a Peltier cooling device generally useful in cooling electronic devices, especially those which are formed of high Tc superconducting materials. The Peltier device of the invention is formed on a micromachined membrane structure to assure good thermal isolation and to intimately integrate the cooling device with the electronic device it is to cool.The membrane is formed by selective, controlled etching of a bulk substrate of a material such as silicon. The Peltier device is formed by selectively implanting or depositing appropriate dopants to form n-doped and p-doped segments on the membrane with a junction between the differently doped segments at the approximate mid-point of the membrane.

Abstract: An apparatus for calibrating and supporting an extruded film blown up into a film bubble made of a synthetic melt in an inflation extrusion installation consisting of supporting means driven by link rods whose inner ends are articulated in the median zone of each supporting means, and whose outer ends are articulated to brackets, which form parts of frames that carry spindle nuts at at least two points, and axially parallel screw spindles which are mounted on the basket-shaped frame and are provided with drive means, and have thread sections provided with threads of opposite hand screwed into said spindle nuts; that at a distance from one of said link rods, there is arranged an additional link rod parallel thereto and whose respective ends are articulated to a respective said supporting bar and to a said bracket.

Abstract: A winding spindle includes a plurality of support and drive rings mounted for free rotation thereon. The drive rings carry and drive winding cores, which have been slipped over the drive rings. The drive rings are able to be non-positively coupled, by their lateral annular flanks, with thrust washers. The thrust washers are connected, in a torque transmitting manner, and slidingly, with the winding spindle, and are acted upon by a thrust. In order to couple the support and drive rings to the winding spindle with an essentially constant torque along the length of the winding spindle, endless hose sections are associated with each thrust washer. The endless hose sections act to press the thrust washers directly against respective flanks of the support and drive rings with uniform force.

Abstract: Apparatus for slitting a web (50) into narrower webs or strips comprises a plurality of cutters (45, 46), which are movable into engagement with the web to be slit and are carried by cutter holders (4), which are adjustable transversely to the web by positioning means (7). The cutter holders (4) are freely slidably mounted on a common track (2, 3) and are adapted to be fixed in position on said track by clamping or detent means (21, 22), which are adapted to be released by a control device (62). A feeder (7) is provided, which is parallel to the track (2, 3). The cutter holders (4) are adapted to be clamped or to be resiliently locked to said feeder under the control of a control device (62) so as to permit the cutter holders (4) to be displaced by the feeder to their desired positions.

Abstract: In apparatus for winding web material successively onto separate winding cores, the material is fed from a supply via a central guide roller to alternate winding assemblies carried by rotary frames. The apparatus has left- and right-hand rotary frames on opposite sides of the guide roller respectively and there are two winding assemblies on each frame. The winding assemblies can be moved along the frames in horizontal tracks, and the frames can be rotated so as to alternate the positions of the respective winding assemblies relative to the guide roller. The apparatus includes associated web cutters and slitters both for transverse cutting and lengthwise slitting of the web material so that full-width web rolls can be wound, or separate rolls can be wound from adjacent strips which have been slit longitudinally from the web.

Abstract: Flattening and take-off apparatus for use with a device for providing a blown tubular film. The apparatus includes a flattening device for flattening the tubular film, and a cutting device for cutting one lateral edge of the flattened film. A pair of pinch rollers is provided and is driven to carry the cut and flattened film to an unfolding device, which is defined by a pair of edges that are inclined relative to the direction of movement of the film web, and over which respective ones of the juxtaposed portions of the cut flattened web are adapted to pass to define a single ply web. The pinch rolls include removable spacing rings to prevent the formation of a fold line on the opposite lateral edge from the cut edge of the flattened film. The unfolding device is movable laterally and parallel to the direction of movement of the film.

Abstract: Folding elements for forming gussets in a tubular film are provided in the mutually opposite open areas between a pair of flattening plates and the plates are reciprocable in the axial direction of the tubular film for an adjustment of the depth of the gussets. The folding elements are mounted to be pivotally movable in all directions and are guided to be transversely displaceable relative to the axis of the tubular film. Adjacent to their mutually opposite, upstream ends the folding elements are provided with adjusting means for imparting a pivotal movement which is transverse to the direction in which the depth of the gussets is adjusted and/or about their longitudinal axes in dependence on a measured deviation of the outer fold lines from their desired position. Sensors are provided for detecting the location of the outer fold lines of the gussets formed in the tubular film.
