Abstract: An apparatus is disclosed for filling spacer frames for insulating glass with hygroscopic granulated material wherein the conduit connecting a storage tank with the discharge opening for the granulated material exhibits a section having a relatively large cross section and a section having a relatively small cross section, which latter section is turned in the upward direction and the axis of which is offset in the upward direction with respect to the axis of the section having a relatively large cross section. This apparatus is utilized, for example, in a machine for filling spacer frames for insulating glass including two processing arrangements with which holes can be produced in legs of the spacer frame, granulated material can be introduced, and the holes can be resealed.

Abstract: A tool holder assembly which comprises a tool holder adapted to be connected with a machine spindle for rotation together therewith, a stationary support member for rotatably supporting the tool holder and adapted to be connected to a fixed portion of the machine, a fluid supply circuit defined in the tool holder for the supply of a cutting fluid from an external source thereof towards a fluid discharge passage defined in a machine tool replaceably carried by the tool holder, and a vane-type displacement pump for forcibly pumping the cutting fluid from the fluid supply circuit to the fluid discharge passage in the machine tool for pouring the cutting fluid onto the workpiece being machined by the cutting tool. The displacement pump has its rotor constituted by a portion of the tool holder, and a pump casing constituted by a portion of the stationary support member.

Abstract: An apparatus and method are disclosed for reducing the oxygen concentration at the interface between a cutting tool and a relatively rotating metal workpiece. The apparatus comprises (a) a supporting means for holding the cutting tool in a predetermined position relative to the workpiece, and (b) means effective to direct a plurality of discrete flows of inert gas between the cutting tool and workpiece in a manner to substantially reduce the oxygen concentration in the zone to a predetermined level. The method comprises (a) directing a first stream of inert gas closely adjacent the interface, and (b) directing a second stream of inert gas to at least partially surround the first stream.

Abstract: A table (1) revolving intermittently and carrying on its periphery piece-holder grips, has central openings (11), which make possible the discharge of working shavings and wastes at the center of the table itself (arrow 12) and not at the periphery (arrows 7, 7') as now is done. This makes possible direct discharge of the working shavings and wastes in the collection container underneath and avoids clogging and stopping of the machine for cleaning which requires the presence of additional labor and limits production. Nozzles (13, 13') direct fluid radially inwardly to assist in this central discharge of shavings and wastes.
