An abrasive wheel assembly, preferably an abrasive cut-off wheel, includes a plurality of segments, each of which comprises an embedded fixing or securing plate, preferably metal, that is inserted to a certain degree into the segment and has a projecting rim part securable to a circular blade. The segment further comprises a core material, e.g. glass fiber, that extends over the total height of the segment.

Improvements in or relating to an abrasive wheel

An optical instrument, for example a field-glass, in which the image-erecting system, the eyepiece tube and the objective tube are embedded in synthetic resin to form the housing of the instrument. The image-erecting system and the eyepiece and objective tubes and, if required, the hinge mechanism, are wholly or partially surrounded in cast resin to make a rigid core and this rigid core is partially or wholly enclosed in foamed synthetic resin.
