Patent ES-342415-A1 (ES)
Title: A Method of Obtaining Colloidal Solutions of Starches in the Cold
IPC: C08B31/00
Filed: 1967-06-28
Abstract: Starch complexes soluble in cold water are made by heating an aqueous suspension of starch at a temperature below 100 C. in the presence of at least one high M.W. colloidal ester of a polysaccharide represented by the formula wherein n denotes a high polymerization number and M E is Na, Ca, Mg or K, until the starch is dissolved, whereupon the resulting complex is recovered. In examples, cassava, maize and potato starches are treated with carragheen, optionally together with guar gum, and the reaction product is recovered by coagulation with a polar organic solvent, e.g. isopropanol or by spray- or drum-drying. Other colloids, coagulation solvents and recovery methods are disclosed.
Patent ES-346338-A1 (ES)
Title: Methods of removing carbon oxysulfide from gases
IPC: C10K1/34
Filed: 1967-10-23
Abstract: Fuel gases which contain O 2 and COS are contacted successively with a hydrogenation catalyst to convert the O 2 to H 2 O, and with a catalyst for the conversion of the COS to H 2 S and CO or CO 2 . The prior removal of the O 2 permits the COS-conversion to be performed at a relatively low temperature, e.g. 80 to 120 C. The hydrogenation catalyst is preferably sulphided and contains a Group VI and/or Group VIII metal, e.g. sulphided cobalt molybdate on alumina permitting O 2 -conversion at 70 to 120 C. The COS-conversion catalyst is preferably alumina, e.g. containing an oxide or oxides of a Group VI and/or Group VIII metal, e.g. cobalt molybdate, or a highly concentrated aqueous alkali metal phosphate solution, e.g. incorporated in an alumina carrier. Both catalysts may be located in the same reactor.

Filed: 1968-12-17
Abstract: To facilitate maintainance and cleaning of individual units of a break spinning frame each unit consists of the houses 15, 16 which are normally lockably arranged together but which may be tilted away from each other, one housing 16 being pivotably attached to the frame and the other housing 15 being pivotably mounted at 39 on that housing. Housing 16 contains feed and cambing rollers 8, 5 and the inlet and outlet channels 28, 30 while the other housing 15 contains spinning chamber 3, which may be arranged for axial adjustment therein. Housing 15 has a narrower portion through which the shaft 41 of the spinning chamber extends so that it can be driven by belt pulley 2 or a chain drive common to all the units. Narrower portion of chamber 15 has a pivotably secured lever 45 mounted thereon which automatically limits the amount of relative opening of the housings 15, 16 by its contact with vertical wall 13 of the frame and simultaneously causes pulley 44 of shaft 41 to be brought out of engagement with the drive belt 2. A lock and catch device 47, 48 normally holds the housings 15, 16 lockably together, a sealing element 56 surrounding the spinning chamber engaging projection 36 on housing 16. The catch device is manually released when a sensing device 34 senses that no yarn is passing through channel 30, 33, the device 34 also actuating an electromagnetic clutch in the drive of the feed roller which causes the feed roller to cease to be driven.- For greater access to the housings lever 45 may be manually deflected to disengage the wall 13 so that the housings may be further tilted to a position defined by a stop 49 (see Fig. 6). A spring biased pressure table may be provided in the housing 16, which table is resiliently urged against the feed roller, an entry condenser funnel being formed in the pressure table. Reference has been directed by the Comptroller to Specification 1,084,664.

Patent ES-441424-A1 (ES)
Title: Dummy for teaching artificial insufflation
IPC: A61M16/00
Filed: 1975-10-02
Abstract: A dummy for teaching mouth-to-mouth and mouth-to-nose resuscitation, has a head shaped to generally correspond to a human head simulated mouth and nose openings and a trunk connected to the head by a neck. The trunk has a hollow part simulating the human thorax. The trunk defines an air-tight, self-supporting container which simulates the human torso and lungs. The container has an oblong cross-sectional configuration at least in the zone of the thorax and is connected with the mouth and nose openings by means of a conduit simulating the human windpipe. The trunk wall is resilient at least in the zone of the thorax to undergo outwardly directed elastic deformations by the pressure of insufflated air for effecting changes in the volume of the container in response to insufflation and simulate the movement of the human thorax. The volume of the container is so chosen relative to its resilient properties that the insufflation of the same air volume to be insufflated into the lungs of a human being during correctly performed mouth-to-mouth and mouth-to-nose resuscitation generates the same pressure in the container as in the human lungs. Similarly when insufflation is terminated, the insufflated air, due to the resilient properties of the trunk wall, is forced out of the container which returns to its undeformed shape, thereby simulating the expiration and movement of the human thorax. Thus, the container wall has a resistance to insufflation through either of the openings that is comparable to a corresponding resistance of human lungs and further, the container simulates the movements of a human thorax during mouth-to-mouth and mouth-to-nose resuscitation.
