    Abstract: A method of recycling a mixed plastics waste comprises introducing into an extruder a feedstock comprising a first plastics material having a first melting point and, a second plastics material having a second melting point higher than the first melting point. The feedstock is passed through a barrel of an extruder where the barrel has a working volume containing an extruder screw through which the feedstock passes where the temperature of the feedstock in the working volume is above the first melting point and below the second melting point. An extrudate is extruded from the barrel. The extrudate comprises the first plastics material in a liquid state and the second plastics material in a solid state, the rate of rotation of the extruder screw being adjusted to maintain the temperature in the working volume above the first melting point and below the second melting point. The first plastics material may comprise up to 20% by weight of the feedstock. The first plastics may be low density polyethylene (LDPE) and the second plastics material may be high density polyethylene (HDPE). A non-plastics material may be contained in the mixed plastics, which may be a metal.

    Abstract: A LED light source includes a longitudinally extending first light guide, a housing, and a cartridge. The first light guide has a longitudinally extending light emitting face. The light emitting face has a first end face and a longitudinally spaced apart second end face. The housing has a first side proximate the first end face of the first light guide. The cartridge is mountable to the first side of the housing and has at least one LED on a first face of the cartridge. The first face extends generally transverse to the first light guide when the cartridge has been mounted to the housing. When the cartridge is mounted to the first side of the housing, the first face of the cartridge is adjacent the first end face. A LED light bulb is also disclosed.

    Abstract: A hand vacuum cleaner has two nested cyclonic stages. Various designs for the dirt collection chamber of the second cyclonic stage and the design of multiple second stage cyclone inlets, which may use directing members, are provided. A length of the second stage cyclone chamber may be shorter than a length of the first stage cyclone chamber. A screen may be positioned laterally outwardly from the second stage cyclone to define a passage positioned between an inner side of the screen and the outer wall of the second stage cyclone wherein the screen may extend axially at least about 70% of a length of the second stage cyclone chamber. Different designs for emptying first and second stage dirt collect ion chambers are also provided.
