Patent ES-389073-A1 (ES)
Title: Turret mounted flying splice unwind
IPC: B65H19/18
Filed: 1971-02-25
Abstract: Unwinder for rolls of paper having individual tape drives engaging the peripheries of the rolls for unwinding the rolls at a uniform linear velocity. The rolls are carried at opposite ends of a turret mounted for adjustable movement about a horizontal axis and moved into its selected position of adjustment by power. The turret support sets of diametrically opposed core shaft chucks for core shafts carrying the rolls of paper. As one roll of paper is being unwound the turret is moved into position to pick up a new roll. The new roll is then positioned in the position formerly occupied by the expiring roll. As the expiring roll is unwound to within a few inches, a knife on a splice arm is activated to shear the end of the expiring roll. A roll on the splice arm is then moved to engage the end of the expiring roll with the new roll and splice the end of the expiring roll to the new roll and carry the new roll to the sheet run.

Title: Nozzles of fluid dispensing valves of the automatic shutoff type
IPC: B67D7/48
Filed: 1973-01-12
Abstract: An improved nozzle for a liquid dispensing valve of the automatic shutoff type placed at the end of a hose for the filling of automobile tanks is euipped with an automatic pneumatic device which shuts off the valve when the tank is filled to a level near the edge of the tank filler hole, comprising venturi and passage means controlled by a manually-operated lever which, when the valve is open, generates a negative pressure in an associated conduit within the main liquid outlet tube, the associated conduit being closed off at its end and slightly shorter than the main tube in which it is incorporated, part of the external wall of the associated conduit corresponding, at least at its end, to part of the internal wall of the main tube. The control of the shutoff means is effected by a manually-operated lever and through a mechanical linkage which includes an element for breaking this mechanical linkage, thereby allowing the means to stop the dispensing of liquid without moving the lever, the element being controlled by the device sensitive to the negative pressure generated by the venturi means to which the said device is connected through the associated conduit and a calibrated lateral hole made in the end of this associted conduit leading out to the ambient free air. A second calibrated hole is provided at the end of the associated conduit and in its axis leading into the main tube and a third hole of larger diameter is located laterally in the main tube, downstream of the end of the associated conduit and in its immediate vicinity, leading out to the ambient air, so that when the liquid in the tank covers almost simultaneously the three orifices of the end of the valve, the simultaneous increase in the pressure drop in the two calibrated orifices produces the immediate operation of the automatic-shutoff device of the valve.

Patent ES-460847-A1 (ES)
Title: Hydrocurable oxazolidine isocyanate prepolymer compositions
IPC: B60T17/08
Filed: 1977-07-19
Abstract: The present invention is concerned with a hydrocurable composition suitable for use as coatings, adhesives or grouts. The composition contains oxazolidine compounds and free isocyanate group containing prepolymers. The prepolymers are obtained by the reaction of polyisocyanates with special types of dispersions wherein the dispersed phase is synthesized in situ in a dispersing media of polyhydroxyl compounds. The dispersed phase may be a free radical addition polymer, an aminoplast polycondensate or a polyisocyanate addition product. In the last case, the non-isocyanate reactants used to form the dispersed phase are substantially more reactive with isocyanates than the dispersing media. An especially preferred composition is based on urethane oxazolidines and prepolymers of aliphatic or cycloaliphatic isocyanates with dispersions of isocyanate hydrazine or hydrazine hydrate condensates in polyhydroxy-polyethers having molecular weights of 200 to 16,000.
