摘要:
A forming tool and method for its use with flat pre-preg composite laminate assemblies which incorporates a mandrel segmented into multiple forming blocks, the forming blocks sized to receive a draped composite laminate assembly with all portions of the composite laminate assembly spaced from a shaping surface on each block. A spline plate engages the shaping surface of the forming blocks to provide a neutral axis for maintaining the entire composite laminate assembly in tension during forming. In the exemplary embodiments, the draped composite laminate assembly is formed to the forming blocks from the flat composite laminate assembly and maintained in contact with the forming blocks using a vacuum bag. The mandrel forming blocks arc then displaced to a desired curvature on the spline plate.

Apparatus are provided for attaching to a composite tape lamination machine in order to remove composite scrap tape material from a backing paper. When a moveable member is in one position composite non-scrap tape material on a backing paper is directed along a path to avoid a removing member and keep composite non-scrap tape material on a backing paper. When the moveable member is in another position composite scrap tape material on a backing paper is directed along a different path to contact the removing member and remove composite scrap tape material from a backing paper. Composite scrap tape material may be disposed in a scrap disposal member. Backing paper having attached composite non-scrap tape material and not having attached composite scrap tape material may be spooled using a spool roller.

摘要:
A device for grinding spices such as salt, pepper, cinnamon, etc. has a grinder rotor which has a removable keeper member which facilitates the ready removal of the rotor for cleaning or replacement. The grinder elements are made of ceramic material such as alumina silicate which eliminates the possibility of corrosion or rusting as with metal parts. The mill provides dual grinding action by utilizing separate grinding elements to provide either coarse grinding or fine grinding, as may be desired. For coarse grinding, the condiment only passes through the coarse grinding element while for fine grinding, the condiment first passes through the coarse grinding element and then passes through the fine grinding element.
