Patent ES-308208-A1 (ES)
Title: Improvements in or relating to foundry moulding mixtures and a method of using same
IPC: B22C1/22
Filed: 1965-01-16
Abstract: A reactive moulding composition comprises a granular refractory material mixed or coated with a phenolic novolak resin in which the phenolic nuclei are linked together predominantly through their ring positions ortho to the phenolic hydroxyl group and a curing agent for the phenolic resin. The curing agent is preferably hexamethylenetetramine and suitable refractory materials are sand, zircon, quartz, alumina and carborundum. A mould release agent such as wax, plumbago or graphite may also be added to the composition. The composition may be prepared by heating the granular refractory material to between 120 DEG C. and 160 DEG C., adding the said phenol novolak resin and mixing until substantially homogeneous, adding a curing agent for the phenolic resin and cooling the mixture so formed by the addition of water while still mixing and while the phenolic resin is still fusible. The composition may be moulded to form shell moulds or cores. Phenolic novolaks in which the nuclei are united through the positions ortho to the phenolic hydroxyl group may be prepared by reacting 1 molecular proportion of phenol with preferably 0.6-0.7 molecular proportion of formaldehyde in the presence of a catalyst such as zinc borate, zinc acetate, zinc benzoate and cadmium acetate.

Title: Filter plant
IPC: F24F13/28
Filed: 1965-02-03
Abstract: In a gas filter comprising a plurality of filter pockets 2 each opening at a lower corner to a slot 5 in the wall 4 of the filter housing, each pocket communicates through a separate valve 10 either with filtered air outlet 7 or a supply of reverseflow scavenging air c, the valves 10 each comprising a tongue 12 having spaced apertures which slides between tongues 11,13, apertures in tongue 12 aligning with those in either the upper or lower part of tongue 11 (Fig. 2, not shown). The reverseflow air may be induced from atmosphere by a sub-atmospheric pressure in the filter housing. In operation, pockets in positions one and two, then those in positions two and three, and so on, are subjected to pulsating reverse flow by repeated actuation of their solenoid-controlled valves 10, whereby successive spaces between adjacent pockets are subjected to reverse flow from both sides, and dust dislodged therefrom falls into a hopper rather than being carried on to adjacent normalflow pockets.
