Title: Contactless web guide system - for endless foils based on nozzle with COANDA guide surface
Inventor: JOKIOINEN ILKKA
IPC: F26B13/20
Filed: 1990-02-09
Abstract: A system of nozzles for the contactless guidance and treatment (drying, heating, cooling) of webs of paper and similar endless webs has at one end of the top of an air chest, a curved COANDA air guiding plane with a first nozzle, directed at right angle to the web. At the other end, a second nozzle is directed parallel to a short extension of the top surface.

Title: Colour transfer cassette for ribbons or film - has provisions for adapting to ribbon materials of different pliability
Inventor: SATO HIROYUKI
IPC: B41J32/02
Filed: 1990-03-13
Abstract: The endless ribbon (R) recirculates through a chamber (3) pulled by drive wheels (7 and 4) on the right of the chamber and is drawn through slots and free running pulleys on the left. These provisions are provided both for fabric ribbons and for nylon film. With due consideration of the rather different pliability of the two materials, slots, pulleys, etc. must be arranged differently for them; however, they can be arranged side by side, and some of them may be shared. If fabric is used, the ribbon is drawn through a slot (23a) in an antechamber (24), pass through slot (25a) and is displaced by bars (26a,26b) to create extra friction. If the less pliable nylon film is used, it must be drawn through a lower slot (23b), then through another slot (25a) and then pass over pulley (28) to the opening in the frame at the top (at 21a).

Title: Prodn. of threads on workpiece using two rollers - has rollers of different dia. or of same dia. but rotating at different speeds
Inventor: ABELE JUERGEN
IPC: B21H3/04
Filed: 1990-07-12
Abstract: Prodn. of threads on a workpiece esp. by re-rolling uses two roller tools (12,13) which are of different dia. (d,d1) and/or rotate at different speeds around their transverse axes (B,C). ADVANTAGE - Design ensures that the tools do not separate and can also run on during the re-rolling. Transverse axes (B,C) pref. lie in parallel planes inclined to one another. Invariable rolling gap (14) is pref. formed between the tools for re-rolling. In an example the different dia. tools are suitable for both passing-through and plunge-cut processes. Tools have channels on their surfaces similar to those in the passing-through process. Due to the difference in the circumferential speeds of the two tools, the workpiece (11) is guided tangentially between the tools. Difference in the dias. (d,d1) determines the number of revolutions of the workpiece. Same affect is achieved if the dias. are the same, but the circumferential speeds differ.

Inventor: KROGMANN UWE DIPL ING
IPC: G05D1/00
Filed: 1991-01-10
Abstract: The condition values are coupled to the measurement values directly delivered by the sensors by a measurement equation m=Hx+ epsilon, where m is a vector of the measured values, x a vector of the state values and H the measurement matrix. The rank of m is greater than that of x. That is a general description os a similar or dissimilar redundant measurement. Characteristic vectors, vi, are set as gap vectors of a characteristic matrix. A parity vector, v, is taken as an element of the parity space that is an orthogonal complement of the signal space. This is defined by a linear combination of the characteristic vectors, vi, and the associated elements, mi, of the measurement vector m. USE/ADVANTAGE - High reliability condition meaurements as necessary in aircraft, nuclear power stations or chemical processes, the sensors involved being gyros, accelerometers, Doppler radar speed measurer, thermo-element for temp-level. Can detect deterioration of sensor signal and categories as "hard, mid-value of soft failure".
