Title: Pleated filter element esp. for air filter - has adhesive layer on pleat side edges
Inventor: BOEHNKE CHRISTIAN DIPL ING
IPC: B01D39/18
Filed: 1992-03-19
Abstract: A filter element consists of a pleated strip of one or more filter material layers, in which the pleats are spaced apart by a preset spacing and are adhesively bonded at their ends, the novelty being that the pleats are bonded at at least their two side ends by an applied layer of adhesive. Pref. the adhesive is a hot melt adhesive, a two-component adhesive or a polyamide or polyurethane adhesive. Processes for prodn. of the filter element are also claimed. The adhesive is pref. applied to the side ends at the edges of the fold apices and bases by means of a slotted nozzle or by a movable transfer device such as a roll or a belt which travels over two or more rollers. Adhesive may be applied to one or both longitudinal ends of the filter element by filling the interior of a strip fold with adhesive, allowing the adhesive to harden and then dividing the strip in the region of the adhesive. USE/ADVANTAGE - The filter element is useful for an i.c. engine air filter, a vehicle interior filter, an industrial dust removal appts. or vacuum cleaner, e.g. in asbestos disposal. It has a sealed joint at the pleat ends and is simple to mfr.

Patent DE-4235399-A1 (DE)
Inventor: BAAS DIETER
IPC: G11B19/02
Filed: 1992-10-21
Abstract: The device moves the fed-in recording medium (7) in a direction perpendicular to a swivelling axis to attain an operational position for action by an optical scanner (14). A reflective photosensor assembly (6, 11) is fitted on the same side of the recording medium as the scanner. This causes a signal to branch off, if the recording medium crosses light rays from the reflective photosensor assembly in an intermediate position different from the operation position. A drivable platen (3) perpendicular to a swivelling axis moves the recording medium. The reflective photosensor assembly switches the platen driver on or off upon a reverse movement to eject the recording medium before the platen releases the recording medium. The reflective photosensor assembly is fitted between the platen and the optical scanner.

Abstract: For sashes (leaves) 3 of windows, doors or the like, which are equipped with a drive-rod fitting 4, in particular a side/bottom sash fitting, which exhibits an actuating gearing with a rotary-drive member which is accommodated in a gearing housing 7 and is intended for the drive rods, the invention proposes the use of a device for supplementary locking 13 which inhibits break-in. Said device has a housing 15 which can be positioned on the room-side end surface of the sash, movably mounts and/or guides at least one supplementary locking bar 18 and can be placed, as a retrofitting and/or supplementing element, beneath the bearing rosette 10 of the operating hand lever 9, and is thereby penetrated by the drive pin 8 of the operating hand lever 9 and also by the anchor screws 11 for the bearing rosette 10 thereof. Provided as adjustment member for the supplementary locking bar 18 is a supplementary handle 20 which is mounted in the housing 15 at a distance from the through-passage region for the drive pin 8 of the operating hand lever 9, and the housing 15 which contains the supplementary locking bar 18 mounts, in the through-passage region for the drive pin 8 of the operating hand lever 9, a cam plate 26 which can be coupled in a rotationally fixed manner to said lever. Said cam plate 26 is provided on its circumference with a plurality of, that is to say at least two, cam surfaces which are offset at an angle of rotation with respect to one another, are delimited in a rectilinear manner at least in certain areas and are arranged at different radial spacings from the axis of rotation of the cam plate. In the housing 15 which contains the supplementary locking bar 18, a slide 38 can be displaced to a limited extent on a plane normal to both the axis of rotation of the cam plate 26 and to the axis of rotation of the operating hand lever 9 and/or rotary-drive pin 8, it being directed towards the movement path of the supplementary handle 20 by its one end and the movement path of the cam plate 26 by its other end. In this arrangement, the slide 38 has a length, by which it alternately blocks, within the housing 15, either the movement path of the cam plate 26 or the movement path of the supplementary handle 20. <IMAGE>

Title: Method for cleaning transformer oils and arrangement for carrying out the method
Inventor: ECKHOLZ KLAUS DR ING
IPC: H01F27/14
Filed: 1993-02-05
Abstract: The invention is based on the object of indicating a process and an apparatus for cleaning transformer oils in transformers, by means of which the greatest possible removal of contaminants is achieved, coupled with a simple and reliable assessment of the degree of purity of the oil. According to the invention, the insulating oil, which has already been reprocessed and is in the transformer, is subjected by means of a special filter device to a predetermined sequence of the steps of filtering and filtering with simultaneous circulation of the oil in the transformer by means of the pumps existing in the cooling unit, the particular duration of these steps being preselected and the sequence being terminated whenever at least one of the following criteria is met over a significant period:     - no longer any significant pressure rise upstream of the filters, - the mean of the breakthrough voltage of the insulating oil has reached a certain magnitude and retains this, and - the size of the particles and their distribution in the oil no longer exceed a preselected value.   The invention is applicable in oil transformers for high voltages and ratings. <IMAGE>

Patent DE-4307497-A1 (DE)
Title: Tool holder
IPC: B23B31/08
Filed: 1993-03-10
Abstract: The present invention describes a tool holder which constitutes an exact tool mounting which can be adjusted according to offset and which in its characteristic feature can also be optimised in the cutting force to remove material or the inherent frequency of the system. The aim of the invention was to realise a tool mounting which is simple to manipulate and can be used by the user without problem completely irrespective of the possible machine-tool type or the drive design of the driven elements. Conventional tool mountings which are commercially available according to the state of the art are not comparable with the tool mounting according to the invention as regards the technical design, such as the geometrical dimensions. By the use of the tool mounting described here, substantially prolonged tool life can be achieved and greater precision in production can be made possible.
