Abstract: A process for production of chemical feedstocks from waste plastics, the process comprising providing a process configuration comprising a fractionation tower (1), a furnace (2), one or more coke drum(s) (3), and a pre-reactor (4), configured so that a bottoms stream (A) from the fractionation tower is mixed with an oligomeric stream (L) and supplied to the furnace, the product stream from the furnace (C) is supplied to a coke drum, and an overhead stream (D) from the coke drum is supplied back to the fractionation tower; wherein the oligomeric stream (L) is obtained as product stream from conversion of a waste plastics stream (B) in the pre-reactor, and has a weight average molecular weight of between 5,000 and 10,000 g/mol. Such process allows for the conversion of a wide variety of waste plastics into valuable chemical products.

Abstract: A comb attachment for a hair clipper includes a base having a depression adjacent a back edge of the attachment and a flexible clip extending outwardly from the back edge. The depression locates a user's finger or thumb when pressing the base until the clip flexes around the edge of the blade. The comb attachment is removed by pulling the clip back around the blade. The flexible clip can be a cantilever having two spaced arch-shaped arms extending from the base and secured to each other at their cantilevered ends by a cross-member. The bottom surface of the cross-member can be angled to facilitate release of the clip and removal of the attachment.
