20160038996 | ARRANGEMENT FOR USE IN THE PRODUCTION OF A SEPARABLE CASTING MOULD - An arrangement for use in the production of a separable casting mould, preferably of a vertically separable casting mould is disclosed. The arrangement can include (i) a mould plate and/or a mould pattern, (ii) a feeder system having a feeder element and having a feeder insert, wherein feeder element and feeder insert delimit a feeder cavity for receiving liquid metal. The arrangement also includes one or more tipping prevention elements which are designed to counteract tipping of the feeder system out of the opening axis about the first end of the feeder element when, in the event of the feeder system being acted on with a force acting parallel to the opening axis and in the direction of the first end, the side wall deforms and the spacing between the first and second ends is reduced, wherein the one or more tipping prevention element(s) are/is spaced apart from the opening axis. | 02-11-2016 |
20140090306 | SILICIC ESTER MODIFIED PHENOL/FORMALDEHYDE NOVOLAKS AND THEIR USE FOR THE PRODUCTION OF RESIN COATED SUBSTRATES - This invention relates to a resin preparable by reaction of a phenol/formaldehyde novolak with tetraethyl orthosilicate in a mass ratio above 28:1, wherein the phenol of the phenol/formaldehyde novolak is substituted or unsubstituted hydroxybenzene or a mixture of two or more such phenols, and to a particulate material coated with said resin. Said particles can be used e.g. in the shell molding process for the production of shell molds and shell cores; and as proppants for use in the hydraulic fracturing process. | 04-03-2014 |
20140048740 | LOW-EMISSION COLD-SETTING BINDER FOR THE FOUNDRY INDUSTRY - The present invention relates primarily to a mixture that is suitable for use in the no-bake process for producing cores and moulds for the foundry industry, and a reaction mixture comprising said mixture and an acid hardener (i.e. an acid catalyst). The present invention further relates to a method of producing a mixture according to the invention and a method of producing a mould or a core. The invention also relates to a mould or a core for producing metal objects and a kit comprising a mixture according to the invention and certain acid hardeners. The invention further relates to the use of a mixture according to the invention as cold-setting binder and the use of said mixtures or reaction mixtures in a no-bake process for producing metal objects. | 02-20-2014 |
