Abstract: A process and apparatus are provided for making desired shapes of urea-formaldehyde suitable for use as insulation from urea-formaldehyde foam. Fluid urea-formaldehyde foam (A) is formed into discrete particles (A') in particle generator (10) which also partially cures particles (A'). After particles (A') are fully cured, they are blended with fluid urea-formaldehyde foam in mixing apparatus (11) which includes blending head (66) to produce mixture (C) which is a coherent mass. Mixture (C) is molded to the desired cross-sectional shape by molding conveyor (12). Cutter (132) cuts formed mixture (C) into the desired length. Thereafter oven (146) is utilized for fully curing the product which is then enclosed in a suitable packaging material.

Abstract: This invention provides a hand tool of the type including a shaft having on one of its two opposite ends a handle and on the other of its two opposite ends socket means for selectively receiving and holding a removable tool tip with improved means to be used in combination with it for storing a plurality of removable tool tips. Basically, the novel tool tip storage means comprises a generally cylindrical storage member having a bore along its long central axis that is mounted on the tool shaft for slideable movement between the tool handle and socket means. The storage member also has a first surface that faces the socket means and is engaged by yieldable means that encircles the tool shaft and extends between and is compressed between said first surface and the socket means.
