Patent DE-3370556-D1 (DE)
Title: Adaptive misposition correcting method and apparatus for magnetic disk servo system
Inventor: SIDMAN MICHAEL D
IPC: G11B5/58
Filed: 1983-05-06
Granted: 1987-04-30
Abstract: A misposition correction system for correcting misposition errors due to spindle runout and other slowly varying errors in a servo positioning system of a magnetic disk storage device. The system includes means for dynamically measuring misposition error with respect to a data track centerline using an anti-aliasing analog filter, means for digitizing the measured analog signal and for removing selected harmonics of the fundamental-frequency of the resulting cyclic error signal, means for transforming the digitized error signal by a matched digital filter whose transfer function contains independently adjustable DC gain, fundamental-frequency gain, and phase lead components thereby to generate a misposition error correction signal that matches the electrical and mechanical response characteristics of the servo system. Further, the system include means to iteratively refine the correction signal by re-applying it to the servo controller when measuring misposition errors with respect to the data track centerline. The system stores separate misposition correction signals for each transducer on the disk so that one of several correction signals can be selected depending on which transducer in the device is selected. The system further includes means for generating a bias force correction signal to correct for non-linear position errors resulting from variations in bias forces acting on the transducer carriage over its range of radial displacement.

Abstract: The aircraft jet engine is carried by a frame (4), and has an engine core casing (18B) acting as a beam. An engine core cowl (30) is made of a composite material that maintains structural strength within a given temp. range. The outer surface of the cowl is cooled  by the ambient airstream. The sidewall (32) of the cowl is stiffened by beams on its inner surface, pref. including axial beams (34) and circumferential beams (38). The beams are tubular and have interconnecting passageways. The cowl is connected to and structurally integrated with the engine casing. Cooling air is aspirated through the passageways to maintain the inner portions of the beams at the same temp. as the outer surface of the sidewall. The flow of cooling air is metered.

Title: Device for depositing flat cover elements, preferably cover sheets, on stacks of flat products, preferably printed products
Inventor: STAUBER HANS-ULRICH
IPC: B65H3/44
Filed: 1985-08-05
Granted: 1988-06-01
Abstract: The cover sheet which is to be placed, is brought into a waiting position above a predetermined conveying path of the stacks of flat articles. The cover sheet is displaced from this waiting position onto one stack by means of a placing element arranged at the end of a piston rod of a piston cylinder unit. The piston-cylinder unit is pivotably mounted about an axis which extends at right angles to a predetermined travel or movement direction of the stack. In its rest position the piston-cylinder unit lies against a pad or buffer which keeps the piston-cylinder unit in an inclined position. By extending the piston rod, the cover sheet is placed onto a stack. The placing element which presses on the stack, is entrained by the further moving stack. Thus the piston-cylinder unit is deflected from its rest position. As soon as a detector detects such a deflecting movement, the detector generates a signal which triggers retraction of the piston rod. The reversal of the movement of the piston rod is thus effected in a simple manner. The inclination of the piston-cylinder unit together with the placing element permits positionally correct placement of cover sheets onto stacks of various heights without requiring a special control arrangement.

Title: Korrekturband fuer thermosensitive papiere.
Inventor: PIETSCH GUENTER
IPC: B41M5/30
Filed: 1985-06-01
Granted: 1991-05-16
Abstract: In this correction tape, a heat-meltable correction film containing an inhibitor effective for the colour forming reaction which has taken place in the thermosensitive paper is formed on a tape-like substrate, in particular in the form of a plastic or cellophane film or a paper. This film is preferably polyethylene glycol. During the correction process, the heat-meltable correction film containing the inhibitor and symbol to be corrected is heated via the thermoprinter. The heated area is made to coincide with the area to be corrected. As a result, the inhibitor has a colour-erasing effect in the melted phase. In addition to the colourless erasure trace, a coloured overprint trace may be present with which the desired letter can then be printed out.

Abstract: The mixing apparatus has a plurality of pump impellers having one common axis and extending parallel to each other. Immediately adjacent pump impellers have opposite directions of rotation. The blading of the pump impellers is such that the currents of the mediums exiting the pump impellers have an as large as possible peripheral component. The medium currents exiting the adjacent pump impellers and having opposite senses of rotation are guided together and generate at the mutual point of contact an extremely high turbulence because the peripheral components of the exiting rotating currents of the mediums are directed oppositely to each other and eliminate each other practically immediately.

Abstract: The web comprises at least two layers of different compositions, one of which forms the basic metal and the other a coating. A composite slab is prepared by surfacing a basic-metal slab, over at least one of its large faces, using a deposition of a filler metal having the composition of the coating, by an electroslag remelting process, and the composite slab is subjected to a hot-rolling processing on a strip mill. The rolling process is continued until a web of the desired thickness is obtained, optionally by means of cold rolling. The invention relates, in particular, to the manufacture of carbon-steel webs coated with stainless steel, which can be used for manufacturing cooking vessels or chambers which have to withstand hot or cold corrosive atmospheres.
