Patent ES-8203143-A1 (ES)
Title: Solar energy collector and system
IPC: F24S90/00
Filed: 1980-12-19
Abstract: Solar collectors whose absorbers are made of a conventional building material form the outer surface of the roof and wall of a building. Air flows behind the absorbers and heat is transferred to the air by expanded metal conductors which extend from adjacent the outside surfaces of the absorbers into the flow passages. Heat from the collectors is stored in a system including a cold tank of liquid, a heat tank of liquid at a higher temperature, and a hot water tank of liquid at an even higher temperature. A heat pump may transfer heat from the cold tank to the heat tank and from the heat tank to the hot water tank. Cold and heat exchangers are provided in each tank for receiving heated air from the collectors and transferring heat therefrom to the liquid in the tank and the exchangers in the cold and heat tanks transfer heat between the liquid in the tanks and air from or to the building. Air flows to and from the collectors, tanks, and buildings in ducts formed by the floor and roof beams and wall slabs.

Patent ES-8201319-A1 (ES)
Title: Test method for determining the magnetic properties of ferromagnetic powders.
IPC: G01N27/00
Filed: 1981-02-11
Abstract: The invention relates to a method permitting the magnetic properties of ferromagnetic powders which are used for the preparation of heavy media for the float-sink dressing of minerals, to be tested. To this end, the invention provides for the ferromagnetic powder to be magnetized in a magnetic steady field at a field strength within the range 600 to 1000 amperes per cm and the magnetized ferromagnetic powder to be demagnetized in a cyclicly decreasing magnetic alternating field at a field strength within the range 1000 to 1500 amperes per cm. Next, the ferromagnetic powder so pretreated is heaped up, in the center portion of a circular plate made from dielectric material and the circular plate is placed on an iron core-provided coil. An alternating current voltage of 180 to 260 volts is applied to the coil, thereby effecting the occurrence of alternating fields of 180 to 220 amperes per cm in the center portion of the circular plate. The ferromagnetic powder heaped up is observed for the figure it is forming under the influence of the alternating fields. The formation of a closed figure around the center portion of the plate indicates unlimited qualification of the ferromagnetic powder for use in a heavy medium suspension.

Patent ES-8506213-A1 (ES)
Title: Methods and apparatus for molten metal fume supression.
IPC: F27D17/00
Filed: 1983-03-16
Abstract: Methods and apparatus for the suppression of fume from a body of molten metal is described. One method involves blanketing the molten metal bath with a mixture of pressurized inert gas and finely divided or atomized particles of water. The inert gas may be argon, nitrogen or steam. An apparatus for carrying out this method comprises an array of nozzles supported adjacent the mouth of a receiver vessel and connected to sources of the inert gas and water. Another method entails burning fuel in the immediate vicinity of the molten metal surface to consume and/or displace ambient air thereby to starve the bath of oxygen and, concomitantly, to suppress the formation of the fume-producing metallic oxide. An apparatus for carrying out this method, particularly adapted for suppressing fume generated in the flow of molten metal through the runner system of a blast furnace cast house, includes a burner from which fuel and air in predetermined amounts are discharged to create flame and disperse it along the axis of the runners. The flame operates to consume ambient air in the combustion process thereby to starve the region over the metal streams of oxygen that would otherwise combine with metal vapors to create fume-producing metallic oxides.

The beater drum pref. comprises two circular end plates with beaters of wire tensioned between the plates. Pref. both cutter drum and beater drum are fixed on a common drive shaft and a single conveyor carries the prod. along both drums' surface. The machine obviates the previous manual task which was tedious and labour intensive as well as being restrictive on output. Prod. quality is enhanced by avoiding the damage of manual knife cuts.

Patent ES-8406588-A1 (ES)
Title: Knitting machine with rocking knock-over bits, and method of knitting therewith
IPC: D04B15/32
Filed: 1983-11-02
Abstract: To insure gentle latch operation, and particularly gentle opening of the latch, the last-knitted loop (36) is constrained to move in the same direction as the needles (2) by controlling movement of sinkers (7) in the same direction as the needles, at a speed slower than needle speed during the raising phase of the needles (FIGS. 5, 6), so that initial movement of the latch occurs slowly and not abruptly to permit faster knitting speeds by reducing stresses on the latch. Conversely, during closing movement of the latch (FIGS. 9, 10), initially, the loop and the needle are lowered simultaneously, the lowering speed of the loop, controlled by the sinker (7) being slower than the lowering speed of the needle. Cast-off can be improved by rapidly controlling the loop by suitable sinker movement (FIGS. 11, 12). The projection distance of the needle can be decreased to at most that of the latch motion distance by constraining the loop, held on a sinker as well as on the shaft of the needle, to a position below the rest position of the sinkers by suitable construction of the sinker cam (15, 15a, 15b FIG. 2).
