Abstract: A blade sharpener comprises a work surface consisting of a single support line. A grinding wheel defines a plane that contains the support line. The grinding wheel is swingable in the grinding wheel plane to a selected position relative to the support line. A blade is supported on the support line in a manner that produces a first cutting surface on the blade cutting edge. The single support line enables mulching blades to be sharpened without having to impart angular motions in space to them as they are fed past the grinding wheel. The grinding wheel is swingable to different positions relative to the support line, thereby enabling the grinding wheel to produce different cutting surfaces on the blades. Swinging of the grinding wheel is achieved by mounting it to a plate that pivots about an axis perpendicular to the grinding wheel plane. A mobile work table having a top plate of finite area is selectively retainable over and removable from the single line support.

Abstract: A nozzle having a series of orifices along a longitudinal length of the nozzle for processing a substrate and which is rotatably adjustable. By the nozzle design of the present invention, liquid is properly distributed along the longitudinal length of the nozzle independently of the angle of the aerosol spray. This allows for the generation of a uniform aerosol stream that is independent of spray angle. The nozzle design of the present invention improves the uniform distribution of liquid within the nozzle, which in addition to providing a more uniform liquid pooling, also substantially eliminates temporal non-uniformities across the nozzle length. Moreover, the present invention is also directed to a nozzle that is translatable in the direction toward or away from the substrate to be processed or parallel to the substrate surface.

Abstract: The invention is based on the method for the resharpening of knives used in size-reduction machines described in U.S. Pat. No. 5,525,094 in which the knives remain installed in a rotatable knife carrier. With this invention the process has been further developed in so far as the cutting edges S are ground one after another respectively at one stop position of the knife carrier 8 in which the radial ray MS of the cutting circle with the direction mS of the grinding feed v at the knife cutting edges S encloses the clearance angle .phi.. So the invention offers the possibility to choose for the cutting edges any clearance angle matching the properties of the material to be flaked.

Abstract: An improved ice skate blade sharpening system utilizing a powered rotating grinding wheel. The system has an adjustable guide for preventing canting and twisting of the blade as it is sharpened, and applies a constant cutting pressure to the edge irrespective of the force applied to the skate by the operator.

The grinding wheel has a central plane perpendicular to the rotational axis, and is mounted to a drive shaft of an electric motor attached to a sliding block biased toward a first position by springs. The guide includes two opposing bearing surfaces spaced a distance apart and a mechanism for adjusting the distance between the bearing surfaces. The central plane of the grinding wheel lies between the bearing surfaces.
