The present invention provides a wear element assembly comprising: (i) a wear element comprising an aperture adapted to receive a fastener, the aperture having a tapered upper region, (ii) a fastener comprising a head region, and a threaded region distal to head region, the head region of the fastener being tapered so as to frictionally engage with the tapered upper region of the aperture, wherein, in use, the threaded region of the fastener is inserted into the aperture and an underlying substrate to locate the wear element on the substrate, and a nut is wound onto the threaded region to secure the wear element to the substrate.

Disclosed is a set of lining plates made of radial tires to protect pieces of equipment from abrasion and to absorb impacts where said set of lining plates comprises a plurality of lining plates made of radial tires that are laid out next to each other in order to line the surface of a given equipment. The lining plates that make up the set are fitted with tongues and grooves so as to allow them to be joined together and make it possible for a perfect fixation through special hook-type screws in order to secure an effective sealing of the equipment surface on which said plates were installed, thus preventing any material from entering the space between the lining plates. The present invention also relates to a method for manufacturing the lining plates of the set using radial tires.

The disclosure relates to a chute liner for mounting on a shelf of a material transfer chute. The shelf has at least one locking formation aperture formed therein. The chute liner has a base for mounting on the shelf. The base has an operatively upper surface that comes into contact with material passing through the chute and an opposed operatively lower surface. The base has at least one mounting formation that depends from the operatively lower surface of the base that defines a passage which in use is passed through the locking formation aperture in the shelf. The chute liner also has a locking member passed through the passage until it operatively engages the mounting formation to lock the base to the shelf.

A dry powder feeding apparatus includes a feeder accommodating a fibrous dry powder, the fibrous dry powder including an active material, a conductive material, and a binder, and a trough adjacent to the feeder, the trough including a bottom and a plurality of bottom pattern portions protruding from an inner surface of the bottom, the bottom of the trough being configured to move the fibrous dry powder discharged from the feeder in a first direction.

A chute liner for mounting on a shelf of a chute having at least one locking formation aperture therein. The chute liner includes a base for mounting on the shelf and an arm extending away from the base to a free end. The base has an operatively lower surface and an opposed operatively upper surface that contacts material passing through the chute. At least one mounting formation descends from the operatively lower surface of the base and passes through the locking formation aperture. The mounting formation forms a passage extending therethrough below the shelf and a locking member is displaced into the passage to operatively engage the mounting formation.

A composite chute for a commercial vehicle includes a metal frame, and a pair of plastic sheets. The metal frame assembly defines a longitudinal axis. The pair of plastic sheets extend along the longitudinal axis and positioned on either side of the metal frame assembly. The metal frame assembly is sandwiched between the pair of plastic sheets.
