Abstract: The disclosure relates to a refuse bin comprising an open topped container for refuse, a shallow base having means to mount the refuse holder on the base and a one-piece removable cover for enclosing the refuse holder, the cover having a lower periphery which engages with the base to support the cover on the base around the refuse holder and an upper part extending above the upper end of the refuse holder and being formed with a port or ports disposed above the upper end of the refuse holder through which refuse may be passed into the holder within the cover and having an integral upper end wall closing the upper end of the cover.

Abstract: A tether anchorage is provided for supporting barrier planks of free standing posts of portable barrier systems wherein an elongated plug with a head, flat intermediate tongue and body has a tether secured to one end of the plug and with the head of the plug being receivable in a slot and apertures in the wall of the post to suspend the plank by the tether.

Abstract: The disclosure relates to a water rescue projectile including an elongate float capable of supporting a victim in water and having one domed shaped leading end and a trailing end to which a flexible sleeve is secured forming a continuation of the elongate float and housing a throwing line attached at one end to the float within the sleeve and having an opposite end to be retained by the thrower. Thus the throwing line is thrown with the float and is payed out from the sleeve in flight to the target.

Abstract: The disclosures relates to a barrier plank for a roadway having spaced triangular section ridges extending across the plank at spaced locations along the length of the plank. Each ridge provides a facet facing at an acute angle to the plank in one direction and a corresponding facet on the other side of the ridge facing at an acute angle along the plank in the opposite direction. Facets have red retro-reflective surfaces and facets have white retro-reflective surfaces. Thus light directed from a vehicle at a shallow angle onto the barrier plank will be reflected back by the facets according to the direction of approach so the plank will be readily visible to the driver. Between the ridges the plank has alternate red and white reflective surfaces to reflect back light directed at normal or near normal angles to the plank.

Abstract: The disclosure relates to a waste bin having an inner steel container for refuse and an outer thermoplastic hood form cover having a domed top wall and side ports through which refuse may be deposited in the container. A lid for the container is mounted on the underside of the top wall of the cover and is supported on a central stud extending through the cover by means of a polythene washer held on the stud by a nut. If a fire should develop in the container the resulting heat will cause the washer to melt releasing the cover to fall onto the top of the container therefore preventing air flow into the container to restrict and extinguish the fire.

Abstract: The disclosure relates to a lock suitable for a refuse bin for securing a cover of the bin to a base of the bin. The lock comprises a body to be mounted on the cover and having a spring loaded projecting plunger to engage the base. The plunger has an inclined cam surface disposed within the body and a key is insertable in the body to engage the cam surface. The key has two spaced longitudinally extending abutments to engage the cam surface in succession to provide an initial and then a final retraction of the plunger. A projection is provided on the lock body adjacent the plunger to engage between the abutments on the key and thereby prevent a simple blade from being used to retract fully the plunger.
