Title: Boiler.
IPC: A47J31/54
Filed: 1979-09-06
Abstract: A system is disclosed for indicating when a flow heater used for vaporization of water and heated by PTC resistors as heating elements therein must be decalcified. Within the flow heater a PTC resistor element is located at a water entry and also at a water exit region. A main PTC heater element is also provided between the entry and exit elements. Separate power supply lines are run to the exit and entry heating elements and an electronic circuit is provided which determines when a difference in current flow in the exit heating element compared to the entry heating element exceeds a given value indicative of the need for decalcification.

Title: Stacking arcuate tiles on trolley - for firing in tunnel kiln after preliminary drying stage
IPC: F27D5/00
Filed: 1980-07-30
Abstract: In a method for stacking arcuately curved roof tiles on a trolley, after they have been dried, for firing in a tunnel kiln, the tiles are put in parallel piles on a refractory base resting on the trolley. Astride a set of piles, e.g. three piles, is placed a trestle-like support made of refractory material. This support then takes another similar set of parallel piles, which are in turn engaged by another trestle support resting on the first support. The final set of piles can rest on the top trestle and do not need any separate enclosure. Since the top layer of tiles is unenclosed, less supports are needed than in known methods, and the cost of heating these is saved.

Patent ES-8308264-A1 (ES)
Title: Security paper having camouflage materials to protect its authenticity features
IPC: C09K11/78
Filed: 1981-12-22
Abstract: A data carrier having excitable marking materials to record information in code and further materials to camouflage them, as well as a method of producing this type of data carrier. The coded information is given in the form of the local presence or absence of the excitable marking materials, and is read by detecting the state of excitation, which can only be done with difficulty. The camouflage materials have the function of preventing the detection of the marking material pattern indirectly by means of a chemical laboratory analysis this camouflage is successful when materials are used which are very similar chemically to the marking materials, and in particular yield the same results as these in a chemical laboratory analysis, but are not excitable with the same means or in the same manner.
Patent ES-8308637-A1 (ES)
Title: A method and an apparatus for measuring the speed of circulation of a flow, stream or jet of a molten material which emits radiation
IPC: G01P5/08
Filed: 1982-06-15
Abstract: Method and apparatus for measuring the speed of circulation of a flow, stream or jet of molten material which emits radiation, particularly a jet of molten glass in free fall. The intensity of the radiation emitted from a limited portion of the flow of material is detected by means of two radiation detectors in two separate locations, which are separated from each other by a preset distance along the travel path of the flow of material. From the output signals of the two radiation detectors are distinguished or separated all the impulse- mode amplitude variations whose amplitude exceeds a preset magnitude. These impulse-mode amplitude variations have their origin in randomly appearing short, discrete, local variations of the intensity of the radiation emitted by the flow of material which are caused by instances of a lack of homogeneity which appear at random in the material (for example, in the form of air bubbles in a jet of molten glass). The interval of time between an impulse-mode amplitude variation in the output signal of the upstream detector, produced by an instance of a lack of homogeneity in the flow of material, and the appearance of an impulse-mode amplitude variation in the output signal of the downstream detector, produced by the same instance of lack of homogeneity of the flow of material, is measured and used as a measurement of the travel time of the flow of material between the detector locations in order to calculate the speed of circulation of the flow of material. It is also possible to determine the volume flow rate of the flow of material, also by measuring the diameter of the flow of material with the aid of a linear formation of photodiodes and by calculating the volume flow rate on the basis of the values of the speed of circulation and the diameter.

Title: Flash butt welding method
IPC: B23K11/04
Filed: 1984-02-07
Abstract: A joint is made between two pieces of steel which have been preheated to a temperature To ( DEG C.) near their abutting surfaces by subjecting first to flashing and then to upsetting.
