Abstract: Apparatus and method reclaim make-up of the type ordinarily supplied in block form by processing broken, unusable random-sized pieces of such make-up into a block of usable make-up of prescribed consistency, size and configuration, by advancing the random-sized pieces through a mesh member of selected mesh size to form intermediate particles of a size appropriate for agglomeration into the block of usable make-up. A measured charge of intermediate particles is established in a compression chamber where the measured charge is compressed by a ram into a mold member to form the block. The mold member preferably includes a tray which selectively is removed to a cosmetic case for ease of carrying and using the reclaimed make-up.
Abstract: Cribbing apparatus for stabilizing a post-accident vehicle against unwanted shifting of the vehicle during a rescue operation in which a victim trapped in the vehicle is to be extricated from the vehicle includes cribbing blocks hinged together for pivotal movement to fill a space between the vehicle and the ground at the site of an accident. A wedge is inserted between the pivotally connected cribbing blocks for operating the cribbing apparatus without jolts and dislocations which otherwise could cause shifting and concomitant increased danger of injury to the victim, as well as to a rescuer. A hinge includes leaves and wings in U-shaped configurations which deter skewing of the cribbing blocks during pivotal movements. The cribbing blocks include grooves for reception of the wedge such that skewing or collapse of the wedge is deterred by virtue of the confined movement of the wedge within the grooves during operation of the cribbing apparatus.
