Abstract: The present invention is a tool holder and quick change adaptor which permits very tight tolerances to be kept when operations are being performed while at the same time permitting quick change of the tool holder. The tool holder and quick change adaptor of the present invention employs a cone and conical recess which are dimensioned such that the two mate with surface to surface contact without locking and provide limited deflection of the tool for precise tool operation.

Abstract: This invention relates to a collapsible transporter module, and the method of using same, for transporting large volumes of unpackaged goods in spaced padded relationship in conventional transportation vehicles such as trains, trucks, ships or containers. The transport module consists of a mounting for the module in the transportation vehicle; a rigid upper frame suspended from the mounting; a plurality of vertically elongate collapsible support members having an upper end and a lower end, the upper end being attached to the upper rigid frame; and a plurality of vertically spaced apart shelf members supported from the support members. When not loaded with goods being transported, the transporter module may be stored in a collapsed mode, thereby allowing the transportation vehicle to return the transporter module to the goods supplier, together with a new payload.
