Abstract: A tile saw having a liquid reservoir and a rotary saw blade protruding through a saw table, the rotary blade picking up liquid from said liquid reservoir as it rotates, the liquid being used to cool the rotary blade as it cuts, comprising a means for maintaining the circulation of liquid from the liquid reservoir to the rotary blade as it cuts and back to the reservoir with no significant splashing or loss of liquid, and means for cutting past the rotary blade without interfering with the maintained circulation of liquid which cools the rotary blade. The rotary blade protrudes through a thin slit in the saw table so that a tile is provided with support as it is cut, whereby precision cuts can be made to the tile.

Abstract: A solid surface cleaning device utilizes a jet of ice particles of ultrapure water for removing contaminants from a surface of a solid such as a semiconductor wafer. The electrical resistivity of ultrapure water stored in a tank is reduced by means of a gas such as dry air or carbon dioxide evolving into the water from a bubble tube disposed in the tank. The water whose resistivity is thus reduced is sprayed from a nozzle into an ice-making container which is refrigerated by the vaporization of a refrigerant discharged into the container. The fine ice particles that are thus generated in the container are sprayed and blasted from a jet spray nozzle onto the surface of the cleaned solid supported within a jet spray chamber. The air inside the chamber is exhausted by a blower together with the ice particles that have been ejected from the jet spray nozzle.

Abstract: The present invention is directed toward flexible embossed supportive backings for coated abrasives, which are used with "sanding" tools. The supportive backing is made from a flexible elastomeric material embossed on one side with a predetermined pattern. The embossment pattern incudes an uninterrupted narrow border along the edges that lay perpendicular to the primary of travel during use, a plurality of narrow grooves within the border which disrupt the surface area of the elastomeric material, and lines of severance that partially separate the edges of the material from its main body.The surface acts as the supportive backing for a coated abrasive as it is worked over a roughened surface. The grooves created by the embossment pattern allow the coated abrasive to deform as it encounters high points on a roughened surface, which allows the abrasive to surround the contours of the roughened surface and greatly increases the efficiency of the coated abrasive.

Abstract: In order that bar-shaped cutters can be ground as accurately as possible, it is essential that the bar-shaped cutters are clamped as close as possible to the surfaces which are to be ground. For this purpose, each bar-shaped cutter is pressed against two stop faces or surfaces by means of two claws of a clamping lever, and the one claw which is closer to the surface to be ground is structured to be more elastic or resilient than the other claw. Particularly, the claw closer to the surface which is to be ground is more intensely pressed or forced against the bar-shaped cutter than the other claw.

Abstract: Tumbling of workpieces is improved by providing a double rotation about two axes which do not intersect but rather lie in mutually parallel spaced apart planes.

Abstract: A portable apparatus for drilling and shaping tile at a worksite has a base assembly with a support arm extending upright therefrom. A horizontal housing, rotatably connected at one end to the support arm, houses a slide assembly which supports a router; the slide assembly including a set of wheels for rolling and guiding the router radially in relation to the support arm. An adjustable annular collar about the support arm fixes the height of the horizontal housing and the associated router with respect to the support arm. Further adjustment of the height of the router in relation to the base assembly is accomplished by using a turnbuckle assembly which lowers the support arm into and withdraws it from the base assembly. A work tray supported on the base assembly has markings to position and guide the tile with respect to cutting tools rotatably fixed to the router for drilling holes in and linearly and arcuately shaping the tile. The cutting tools are cooled and lubricated by a liquid recirculating system.

Abstract: A hand sander for finishing both planar and arcuate surfaces is disclosed which provides a means whereby the flexible abrasive strip is shifted relative to a backup member so that it remains taut irrespective of whether a planar surface, a concave surface or a convex surface is being finished. The base or backup member comprises an elongated flexible strip having hand grips mounted thereon. Loosely coupled to the backup member is a further strip of flexible material having means for clamping opposed ends of the abrasive strip. First and second pairs of cooperating wedges are affixed to the base member and the clamping strip so as to cooperate with one another so as to effect the degree of displacement between the base and clamping member as the base member is passed over an arcuate surface to be finished.

Abstract: A method serves for cylindrical surface grinding of workpieces. A grinding wheel engages a workpiece which rotates in the opposite direction and is fed at a given feeding speed parallel to the axis of the workpiece. The grinding wheel rotates about an axis which is inclined at an angle relative to the axis of the workpiece.In order to achieve workpiece surfaces of low roughness at high machining speeds, in particular surfaces without spiral-shaped surface grooves, one first determines from the given surface roughness, by empirical means, a contact ratio serving as an auxiliary value whereafter the axial length of the first surface is determined and adjusted using a formula. The method is used within a range of values where workpiece diameters of 5 to 250 mm are encountered, the grinding wheel rotates at a speed of 100 to 300 m/s, the workpiece rotates at a circumferential speed of 65 to 200 m/s and the speed of the axial feed is between 150 to 2000 mm/min.

Abstract: An abrasive liquid jet cutting system has a cutting head for directing a jet of ultra high pressure water and grit to a work piece. The jet cuts the work piece in a desired pattern to form a product. The liquid from the jet, grit, and particulate materials of the work piece are collected with a receiver located generally below the cutting head. Controls for both the cutting head and receiver are coordinated to move the receiver along with the cutting head so that the water and particulate materials are collected by receiver. The receiver has an upright tubular member provided with wear resistant sleeves and an upright central rod to absorb the impact forces of the water and particulate materials that move through the receiver. A drive means connected to the tubular body operates to continuously rotate the tubular body, sleeves and rod to distribute the wear around the sleeves and rod caused by the water, grit and particulate materials that impinge thereon.

Abstract: The invention pertains to cutting irregularly shaped glass parts from glass blanks, and providing interior openings or cutouts in the parts, at a relatively high volume. Glass blanks are conveyed one-by-one to a transfer position beneath a shuttle carrier. The shuttle carrier picks up each sheet by means of vacuum cups and transfers it to the table of a cutting machine. A plurality of ganged abrasive jet cutting heads follows a prescribed path to cut a corresponding plurality of parts from the blank. The cutting heads then trace a second prescribed path to provide an interior cutout in each part. The ganged cutting heads may make additional passes to cut additional nested sets of parts from the blank. Upon completion of cutting, a second shuttle conveyor moves into position over the cutting table and, by means of vacuum cups thereon, picks up the individual parts and cutout portions and transfers them to a run-out conveyor for subsequent fabricating steps.
