Patent MX-9707166-A (MX)
Title: Improved grinding wheel for flat glass beveling.
Inventor: RAMANATH SRINIVASAN
IPC: B24D3/00
Filed: 1996-02-21
Abstract: A composite, polymer bonded abrasive wheel is disclosed for grinding operations and especially for use with multiple station, glass beveling machines. The abrasive wheel breaks in quickly and delivers consistent performance with little or no dressing needed over the entire life of the wheel. In one aspect, the novel abrasive wheel includes a concentrically mounted, annular abrasive rim on a cup shaped hub. The rim can contain an abrasive such as diamond or cubic boron nitride which is embedded in a bonding composition that includes amino aldheyde and phenolic thermoset polymers, a plasticizer, and optionally filler. The hub includes a crosslinkable, strong and rigid, engineering polymer, preferably melamine phenolic thermoset polymer, mixed with spodumene in amount effective to make the coefficient of thermal expansion of the hub match that of the rim. The wheel can be made by simultaneously hot pressing rim and hub preforms and without an additional baking step. Optionally the rim and hub can be colored to identify the characteristics of the abrasive, and to help determine that the grinding surface has worn down to the hub.

Title: Process for recovering and disposing of residues produced in cupola furnaces.
Inventor: HENYCH IVO
IPC: C22B7/02
Filed: 1997-11-27
Abstract: A process is disclosed for recovering and disposing of wet residues produced in cupola furnaces and the metals contained therein, the dust being captured by a filter device.

Title: Crystalline silicate catalysts with deactivated outer surface - have pores blocked before contact with deactivation agent
IPC: B01J29/86
Filed: 1982-12-15
Abstract: Some or all the catalytically active sites on the external surfaces of crystalline aluminosilicate and/or borosilicate catalyst are deactivated by (a) making the pores inaccessible to deactivating agent; and (b) subsequently contacting with deactivating agent. Pref., the pores are made inaccessible by saturating the pore vol. of the silicate with an organic component which cannot mix with or dissolve in the deactivating agent, pref. an aromatic or alkylaromatic hydrocarbon, esp. toluene. The deactivating agent is pref. a soln. of alkali metal salt, esp. Na salt, in water, and contact is at 0-200 deg. C for at least 1/2 hr. The modified silicate so prepd. is claimed. A crystalline silicate having different catalytic properties on its external surface from the pore surfaces has (part of) the catalytically active sites on the external surface replaced by catalytically inactive alkali metal ions, esp. Na ions. The catalysts are useful in e.g. hydrocarbon conversions. Inactivation of external surfaces reduces pore blocking, giving a catalyst of increased life and selectivity.
