Title: Surface protection from sun - air-conditions rooms or cabins by using thin strips of wood or metal stacked horizontally one behind the other
Inventor: COST KARLFRIED
IPC: F02B3/06
Filed: 1990-02-13
Abstract: A surface protection from the sun consists of a number of thin horizontal strips of wood or metal (1) stacked close together one behind the other.

Title: Replacement of nozzle into continuous casting mould - moves nozzle into place from waiting position which pushes used nozzle aside
Inventor: BRUECKNER RAIMUND
IPC: B22D11/10
Filed: 1990-07-20
Abstract: To insert an immersion nozzle into mould of a continuous casting assembly, the nozzle (1) is initially simply laid in a waiting position near the opening (2) of the vessel (3). The nozzle (1) is then moved at right angles to its direction of movement, in the waiting position and then transferred into the pouring position, if necessary pushing the worn nozzle aside. - While the nozzle (q1) is being pushed into the pouring position, its head plate (6) slides against guide plates (8) to press it against the base (7) of the vessel (3). After the nozzle (1) has been inserted into the mould (15), the transfer mechanism is wholly, or at least in part, withdrawn from the area round the upper opening of the mould (15).

Title: Diagnosing mechanical characteristics of machine having rotating parts - detecting damage and/or wear by evaluating vibration signals arising
Inventor: LATTKA ALEXANDER DR ING
IPC: G01H1/00
Filed: 1990-07-25
Abstract: Vibration signals arising from the rotating parts of the machine are measured and prefiltered and digitised in a transient recorder (TR). They are evaluated in a freq. range by freq. transformation.  At least one characteristic value is obtained that represents the relation of the values of an harmonic freq. (i=0.5;2;3) to the basic freq. (i=1) over a predetermined period. A signal processor (SP) limits the freq. band and claculates the freq. function e.g. by a Fast-Fourier Transformation (FFT).  The separate harmonic freq. are searched for at the same time over the spectral plane. USE/ADVANTAGE - Simple automatic monitoring of machine condition, e.g. fissure in shaft or blade of turbine, wear of gears.

Title: Reducing scale formation during cooling of rolled steel - comprises passing through pressurised water cooling unit to prevent air contact
Inventor: KRENN WALTER
IPC: B21B45/02
Filed: 1990-11-13
Abstract: The method for achieving reduced scale formation during cooling of rolled steel and other materials passing through a pressurised water or some other closed cooling unit is characterised by the fact that the cooling unit directly adjoins the forming unit. Such an arrangement prevents the hot rolled material from coming into contact with atmospheric air. Pref. the temp. of the material is measured prior to its entry into the forming unit, and is altered accordingly. USE/ADVANTAGE - The method is used to virtually eliminate scale formation on steel and other rolled materials. The specific advantages resulting from the method are increased productivity and improved uniformity of the cooling process.

Title: Measuring process graphically displaying digitally registered seismological data in compressed form - separating data streams delivered from sensors to central computer into blocks scanned to produce characteristic values
Inventor: STOLL DIETER DR
IPC: G01V1/34
Filed: 1991-01-17
Abstract: The seismological data are derived from natural or artificially produced vibrations of the earth, e.g. from shock waves.

Title: Weft supply to air and water-jet looms - utilises equipment to determine number of weft breaks and their causes
Inventor: MATSUI ISAMU
IPC: D03D47/34
Filed: 1991-03-18
Abstract: Air or water jet looms take weft from supply reel. Weft breaks are assessed from reel dimensions in conjunction with tension on the weft. The reel is measured progressively during unwinding, and the tension is measured constantly. At the same time the number of breaks is recorded. The reel of weft (114) is pref. mounted on a stand (114) which has a spindle (102). When unwinding, the yarn reduces the dia. of the reel, which is monitored by the equipment (111). This may consist of semiconductors and photo-electric devices (113). It is also possible to determine the reduction by taking time and lengths of yarn on the reel. Alternatively, the weight of the reel, with the gradual redn. in wt. as it unwinds, can be used as data. USE - To equip the loom with apparatus to determine the cause of weft breaks. The data provided by the appts. may be used to take precautions in order to avoid weft breaks.
