Title: Table structure for an electro-erosion apparatus
IPC: B23H11/00
Filed: 1962-11-15
Abstract: <PICT:0991872/C6-C7/1> Apparatus for holding a workpiece W for an electro-erosion metal removal operation comprises an electrically conductive rotatable table 21 having a central post 22 extending downwardly, a first electrically conductive plate member 27 in fixed relation with the post so as to rotate therewith, the under surface of the plate member being in resilient slidable engagement with the top surface of a non-rotatable second electrically conductive plate member 31 to which current is supplied through a bus-bar 46. Using the apparatus, successive workpieces mounted on the table can be brought to a single working position, e.g. an electrolytic grinding wheel, or a given workpiece can be presented to different work stations.  The use of the contact plates 27 and 31 reduces electrical resistance between rotatable and non-rotatable parts in the current supply to the workpiece.  Indexing means for the rotatable table 21 is provided by a reciprocatable pin 52 which extends into slots 26. Specification 861,039 is referred to.

Abstract: Hard and abrasion resistant cast resin surfaces are made of a cured composition of an unsaturated polyester resin and at least 50% by weight of sand particles, the resin and particles being bonded by a bonding agent having at least two reactive groups one of which selectively reacts with the sand particles and the other with the resin.  The particles may be treated with the bonding agent before compounding with the resin, will preferably have a slight moisture content before treatment and are subsequently dried before compounding.  Specified bonding agents are alkenyl silanes and siloxanes, Werner-type methacrylato-chromic chloride complexes and allyl (or substituted allyl) silicates, numerous examples being given.  The resin-sand compositions may contain the ingredients disclosed in Specifications 792,334 and 779,613. The Specification contains lists of suitable polyester components, comonomers, inhibitors, plasticizers (which may be used to replace part of the solvent comonomer), catalysts, accelerators and suspending agents.
