Abstract: A fluid-driven ring saw includes a ring saw blade that is supported and driven by a fluid. The fluid-driven ring saw can include one or more pairs of fluid nozzles. Each pair of fluid nozzles can include a first fluid nozzle separated from a second fluid nozzle by a gap. The ring blade can be positioned within the gap. The ring blade can include a plurality of holes. The one or more pairs of fluid nozzles can deliver fluid jets that impinge upon the plurality of holes of the ring blade to drive rotation of the ring blade. The ring blade can be driven without direct contact of a mechanical linkage, such as a belt or chain. The ring blade can be relatively thinner than ring blades driven by mechanical linkages.

Abstract: A pet toy comprising a rod that has a proximal end and a distal end. The rod becomes increasingly flexible from the proximal end to the distal end. The pet toy further comprises a flexible line member connected to the distal end where a ratio of a length of the rod and a length of the flexible line member can be from about 5:1 to about 50:1. The connection between the distal end and the flexible line member comprises a pin with a needle and a head where the needle can be inserted into the distal end, and a connector that is mounted on the head.

Abstract: A flat-sided annular blade for a blade ring saw for cutting hard materials such as tile along straight paths and curved paths in which the workpiece is moved through the central portion of the blade. In addition to the usual sintered abrasive diamond coating on the outer peripheral portion of the blade, the inner peripheral portion preferably is tapered to a curved inner edge and also is coated with an abrasive, preferably an electroplated diamond coating providing smoother sawing operation and a finishing action on the workpiece.

Abstract: The present invention relates to a blade ring saw assembly in which the blade is a narrow, flat-sided metal ring having a radial width at least twice, and preferably four to six times, its thickness and has a diamond abrasive coating covering its outer peripheral edge and a portion of each sidewall of the ring. The blade ring is supported on a base from beneath the working surface, and projects upwardly to expose more than one-half of the blade ring for cutting of hard and thick workpieces, such as tile and stone, including both curved cutting and straight cutting. The blade ring is supported beneath the work surface by a plurality of roller guides above its radially inner edge and an endless drive belt having a run that extends beneath the blade ring so as to both support and drive the blade ring.

Abstract: An apparatus for the accurate sawing of very hard materials is described, comprising a rigid circular wire saw and an assembly providing support, guidance and drive for the wire saw. A plurality of saw-guides constructed of guide wheels having a rubber circumference bearing surface, are used to support and guide the rigid circular wire saw. In the preferred embodiment, a disk shaped drive wheel, driven by an electric motor, applies frictional pressure and linear impetus to the wire saw, causing it to rotate at high speed. The apparatus may be scaled in size to accommodate any given maximum thickness of workpiece material.
