Patent ES-471004-A1 (ES)
Title: Roll mill for feeding material to the roll gap
IPC: B30B15/30
Filed: 1978-06-21
Abstract: A roll mill has sealing devices pressed against the ends of the rolls to seal the roll gap so that material being processed is not squeezed out (such as oil seed during treatment for flaking). The sealing devices include flow guides (such as recesses therein). A curtain of material, wider than the rolls are long, falls onto the roll gap, and so much of it as exceeds the width of the rolls is guided by the flow guides into the roll gap from beyond the ends of the rolls outwardly of the roll ends. This happens because the flow guides themselves extend near the roll gap but stop short of the roll ends. The sealing devices may include a sealing pin surmounted by an elongate wedge member, the two having communicating recesses which together form the flow guide. The mill may have provision for hydraulically pressing the rolls towards each other during flow of material and separating them while such flow is absent a hydraulic connection then presses the sealing pins towards the roll ends while the rolls are compressed and lifts them away from the roll ends while the rolls are separated.
Patent ES-471218-A1 (ES)
Title: Olefin oxidation process.
IPC: C07C45/00
Filed: 1978-06-28
Abstract: Olefins are oxidized to carbonyl compounds, for example, 1-hexene to 2-hexanone, with a Pd/Cu/alkali metal or alkaline earth metal chloride catalyst and a suitable surfactant in a diluent system comprising at least two liquid phases, wherein at least one liquid phase is an aqueous phase, in the presence of free oxygen. The addition of the surfactant to the system provides an improvement in olefin conversion and selectivity to the corresponding carbonyl compound. Suitable surfactants include, for example, quaternary ammonium halide compounds.

Title: Tile shaped glass solar energy collector - with central chamber for circulation of heat carrying fluid between two evacuated insulating chambers
IPC: F24S10/50
Filed: 1978-07-28
Abstract: Solar energy collector has a hollow, translucid parallopipedic body with pref. rectangular cross section made of glass. It is in the form of a tile for covering and protection of houses and buildings. Inside the body are three superimposed chambers, the outer two of which are interconnected. A vacuum is pulled inside these two chambers so they thermally insulate the central chamber. The thermal fluid, e.g. water, circulates through the central chamber via. inlet and outlet orifices. These orifices are connected to orifices of adjacent files, by means, of an impervious seal. On the lower face of the evacuated insulating chamber below the central chamber is a lower reflecting incident light. An anodised aluminium strip which forms an air gap below the outer surface also serves this purpose. Similarly on the lower face of the central chamber through which fluid flows there is an anti-reflecting layer. Used for heating houses or buildings, the collector is easy to instal and replace in the event of damage and can take the place of normal roof tiles. It has good sealing against atmospheric agents and resists corrosion.
