Patent ES-452712-A1 (ES)
Title: Method for fluid conveyance of articles
IPC: B65G51/02
Filed: 1976-10-26
Abstract: A process for conveying thin-walled cup-shaped circular cylindrical articles on a cushion of fluid by positioning them between a plurality of longitudinally-extending members formed with opposing shape-conforming supporting surfaces and having ports therealong for discharging a pressurized fluid against the walls of the article. The magnitude of fluid discharged is controlled to effect an inward deflection of the walls of the article along its trailing open end, imparting a converging taper thereto and producing a force vector for propelling the article in the direction of intended travel along the members. The discharge of fluid from the opposed members is also controlled to produce a separating air cushion between the ends of adjacent articles, resisting impact therebetween during their conveyance along the members.

Title: Discharging process for boxes, esp. for grapes - which are gripped between two conveyor belts and inverted along a C=shaped track (BR 20.6.78)
IPC: B65G15/14
Filed: 1977-11-11
Abstract: Discharging process for boxes consists in gripping the latter by their lateral walls between two parallel, undulating thick PVC transporter belts because of the 'C'-shaped path, the open ends of the boxes, initially facing upwards, are turned upside down to discharge their contents, e.g. grapes. The inclined conveyor belt brings the boxes to the start of the parallel belts with the upper ends open.

Patent ES-8101770-A1 (ES)
Title: Method and apparatus for determining the weight of molten metal in situ.
IPC: G01G9/00
Filed: 1979-12-12
Abstract: Method for rapid and accurate weight determination of molten metal in a slag-containing bath preferably without any necessity for direct gross weighings in a hostile steel works environment or otherwise, by the addition to the molten bath of a known weight amount of a "trace" element (preferably of a type which is completely diluted in the molten metal, to the practical exclusion of the slag) awaiting the even dispersal of the trace element in the molten metal (aiding the speed of dispersal by promoting a boiling action, if necessary) taking a sample of the molten metal analyzing the sample to determine the weight percent of trace element in the molten metal (for example by spectrometric analysis) and determining the weight of the metal from the known values of weight of the trace element added and its weight percent in the molten metal after addition. In the event that a measurable amount of the trace element exists in the molten metal prior to the addition of the weighed amount, then it is also necessary to take a sample of the metal prior to addition and determine the weight percent of the trace element in that first sample. Alternatively, the trace element may selectively dissolve in the slag, thus similarly permitting the determination of the weight of the slag but requiring a knowledge of the net weight of the molten bath if the weight of the molten metal is ultimately required. Similarly, if the trace element used dissolves in both the molten metal and the slag then it will be necessary in this case also to know the net weight of the molten bath (e.g. by crane weighing load cell systems) as well as the weight percentages in the slag (e.g. determined by x-ray fluorescence).

Title: Process for the production of mycorrhizal plants with symbiotic fungi.
IPC: A01G1/04
Filed: 1981-02-17
Abstract: The invention relates to a method of producing plants mycorrhyzated (i.e. having their roots associated) with symbiotic fungi, so as to apply mycorrhyzation to already adult plants and obtain mycorrhyzated plants which can produce fruit-bearing bodies immediately after being planted. The method consists in cultivating a set of young plants in sterile soil, preferably starting from seed, and in mycorrhyzating the young plants grown in sterile conditions, by placing their roots in contact with roots previously mycorrhyzated with the desired fungus and obtained under natural conditions from other plants. The resulting pilot young plants are planted in a sterile greenhouse or sterile nursery, in which already adult plants are subsequently planted so as to be mycorrhyzated, after secondary roots have first been eliminated and the remaining roots have been sterilized. The pilot young plants mycorrhyzate the adult plants with the desired fungus, so that the plants can immediately produce fruit-bearing bodies.

Title: Refrigerator
IPC: F25B1/00
Filed: 1982-03-17
Abstract: A refrigerator comprises a motor- compressor unit (16) having a definite rated power and piston displacement but arranged to operate with different performance characteristics which, in a conventional system, would require different rated power and piston displacement values. This is achieved by varying both the frequency and voltage fed by a variable electrical power supply (26) to the electric motor of the unit (16), the value of the supplied power at any given time being determined by an electronic control system (24) processing temperature data determined by sensors (18, 20, 22) in the refrigerator. As shown the sensors are respectively in the refrigerator cabinet (10), on the evaporator (12), and on the condenser (14). The control system (24) includes a microprocessor and keeps the ratio V/f of the motor supply constant. The system may be used to maximise efficiency by giving the lowest possible condenser temperature and the highest possible evaporator temperature, or to keep the sensed temperatures constant.
