Patent CH-618137-A5 (CH)
Title: Roller conveyor
Inventor: LEHNER-STIRNEMANN MAX
IPC: B65G13/11
Filed: 1977-05-18
Abstract: Rollers (10) which are driven from below via a friction drive (4, 5, 8, 9), and non-driven rollers (11) to form free-running or back-up sections, are mounted between two parallel frame supports (1, 2). At least one of the two frame supports (1, 2) has, as a bearing aperture for the mounting of the ends of the roller spindles, slits which are open at the top. For the friction drive, at least one drive belt (5 and 8, 9) has a strand (7) which extends over the entire conveying length. The slits on the one hand and/or the drive rollers (10) and the free-running rollers (11) on the other hand are so designed that drive rollers (10) inserted into the bearing apertures of the frame supports enter into frictional connection with the drive belt, while free-running rollers (11) inserted into the same bearing apertures do not enter into contact with the drive belt. Skewing of the conveyed material can be avoided by changing the position and/or the length of the driven and non-driven part-lengths of this roller conveyor. <IMAGE>

Title: Gas scrubber - has no moving parts, using spray induced by rising gas stream
IPC: B04C3/00
Filed: 1970-09-24
Granted: 1972-05-05
Abstract: Gas scrubber with no moving parts, no spray-jets to become blocked, and requiring a water supply at gravity head only, eliminating the conventional pumping system. Essentially, a gas stream rising through the scrubber is used to induce a fine spray of liquid into a turbulent scrubbing action of the gas. Scrubbing efficiency is improved if the flow direction of the gas stream is turned, after it has contacted the liquid, through 140 degrees for a limited travel before being redirected upwards. In addition to dust removal from liquids, the scrubber can be used to eliminate a soluble gas from a mixture with an insoluble gas.

Title: Statistical analyser for voltage deviations - used in mfr. of paper, cardboard and films, combined with radioisotope thickness gauge
IPC: G07C3/00
Filed: 1972-10-31
Granted: 1974-05-24
Abstract: Statistical analyser for deviations in voltage proportional to a controlled parameter is for use in mfr. of paper, cardboard and films, combined with a radioisotope thickness gauge. The voltage proportional to the parameter is compared with a stepped potential, giving an output signal when the latter exceeds the former and has a value >= that threshold of the comparator circuit. A path commutator successively frees coincidence circuits in the paths of the analyser and connected each to its counters, each of which is associated with a release circuit. The commutator controls a circuit for forming the stepped voltage, also giving a reference voltage. A flip-flop has one input connected to a release switch of the analyser, and the other connected to the output of the comparator. A supplementary coincidence unit has its first input connected to the output of the flip-flop and its second input connected to the output of the last path of the analyser. A supplementary counter registers those voltages proportional to the controlled parameter which are in excess of max. values of the stepped voltage, and has a release circuit with input from the supplementary coincidence circuit.

Granted: 1975-07-11
Abstract: A fluid feed (or treatment) device for yarns includes a duct having an oblong cross section and a slot extending along its length and through which the yarn can be introduced laterally into the duct. The cross-sectional area of the dust increases towards the downstream end, and at the upstream end are provided two inlet nozzles whose axes pref lie parallel to the axis of the duct and through which fluid can be fed into the duct from a main fluid inlet pipe so that the fluid advances the yarn along the duct. Where the fluid is press. air the device may be used as a pneumatic gun for transferring e.g. yarn from a full to an empty bobbin. The fluid may alternatively be a dye (pref. vapour) or coating agent whereby the yarn is treated whilst also being advanced. The device is easy to operate, quiet, can advance the yarn at high speeds and has olow energy consumption.

Title: Melt-spinning of finer polyester micro filaments, reduces melt viscosity as a function of titer
Inventor: KEMP ULRICH
IPC: D01F6/62
Filed: 2002-07-24
Abstract: Fine (below 0.7 dtex) polyester micro filaments are spun from a low-viscosity, polyester melt. The melt viscosity is related to their titer. It is reduced below a corresponding melt quality for polyester fiber spinning of 1.60 to 1.65.  Fine (below 0.7 dtex) polyester micro filaments are spun from a low-viscosity, polyester melt. The melt viscosity is related to their titer. It is reduced below a corresponding melt quality for polyester fiber spinning of 1.60 to 1.65. The micro filament titer is related to the reduced relative solvent viscosity by equation (1). eta = 0.1052 ln X + 1.649 (1) Where X is the DTY titer in dtex and the spinning velocity is 2500 m/min +/- 10%. Acceptable spinning reliability at a defined filament titer is achieved with the solvent viscosity varying over the range +/- 0.05%. The viscosity is reduced by adding viscosity-control additive(s), and homogenizing. Titers of the spun filaments range between 0.1 - 0.7 dtex, 0.1 - 0.2 dtex or up to 0.35 dtex.  An Independent claim is included for corresponding polyester micro filaments of up to 0.7 dtex. They have a gray scale dyeing uniformity of 4.0-5.0 and a DELTA E value of less than 1.

Abstract: Processing is based on print carriers in the form of security paper webs or security paper sheets, containing security paper prints which are arranged in the manner of matrices in transverse rows and longitudinal rows and on which spoilt notes are identified by a mark which can be read by a reading instrument. The print carriers pass, in succession, by a reading instrument which detects the positions of the spoilt notes and feeds them into a computer for storage, a cancellation printer controlled by this computer, which provides spoilt notes with a cancellation print, and a numbering machine. The numbering mechanisms of this numbering machine are moved forward by the computer in such a way that always the satisfactory security paper prints, placed in succession in any longitudinal row, are serially numbered, the spoilt notes being neglected. Subsequently, the print carries, having passed by another reading instrument, are cut up into individual security papers, the spoilt notes are separated out in a separation device and the remaining, serially numbered individual security papers are assembled to form bundles, each having a complete numerical sequence. In this way, correct and complete numerical sequence of the security papers contained in the automatically produced security paper bundles and security paper parcels is ensured, in spite of the separation of spoilt notes.
