In one aspect of the present invention, a drill bit has a body intermediate a shank and a working face. The working face has a plurality of blades converging towards a center of the working face and diverging towards a gauge of the working face. A first blade has at least one pointed cutting element with a carbide substrate bonded to a diamond working end with a pointed geometry at a non-planar interface and a second blade has at least one shear cutting element with a carbide substrate bonded to a diamond working end with a flat geometry.

In one aspect of the present invention, a high impact resistant tool, having a super hard material is bonded to a cemented metal carbide substrate at a non-planar interface. The cemented metal carbide substrate is bonded to a front end of a cemented metal carbide segment. A stem is formed in the base end of the carbide segment opposite the front end and the carbide stem is press fitted into bore of a steel body.

In one aspect of the invention, a tool has a wear-resistant base suitable for attachment to a driving mechanism and also a hard tip attached to an interfacial surface of the base. The tip has a first cemented metal carbide segment bonded to a superhard material at a non-planar interface. The tip has a height between 4 and 10 mm and also has a curved working surface opposite the interfacial surface. A volume of the superhard material is about 75% to 150% of a volume of the first cemented metal carbide segment.

A high impact resistant pick in a holder having a super hard material bonded to a cemented metal carbide substrate at a non-planar interface. The cemented metal carbide substrate is bonded to a front end of a cemented metal carbide bolster. A bore is formed in a base end of the carbide bolster generally opposed to the front end. A steel shank being fitted into the bore of the bolster at a bolster end of the shank, and a portion of the shank is disposed within a bore of the holder at a holder end of the shank.

In one aspect of the present invention, a high impact resistant tool has a superhard material bonded to a cemented metal carbide substrate at a non-planar interface. The cemented metal carbide substrate is bonded to a front end of a cemented metal carbide segment. A stem formed in the base end of the carbide segment opposite the front end is press fit into a bore of a steel body. The steel body is rotationally fixed to a drum adapted to rotate about its axis.

A cutter for a drill bit used for drilling wells in a geological formation includes an ultra hard working surface and a chamfer along an edge of the working surface, wherein the chamfer has a varied geometry along the edge. The average geometry of the chamfer varies with cutting depth. A depression in the shaped working surface is oriented with the varied chamfer and facilitates forming the varied chamfer. A non-planar interface has depressions oriented with depressions in the shaped working surface to provide support to loads on the working surface of the cutter when used.

In one aspect of the invention, a high impact resistant tool having a superhard bonded to a cemented metal carbide substrate at a non-planar interface. The superhard material has a substantially pointed geometry with a sharp apex having 0.050 to 0.125 inch radius. The superhard material also has a 0.100 to 0.500 inch thickness from the apex to the non-planar interface.

A high impact resistant pick in a holder having a super hard material bonded to a cemented metal carbide substrate at a non-planar interface. The cemented metal carbide substrate is bonded to a front end of a cemented metal carbide bolster. A bore is formed in a base end of the carbide bolster generally opposed to the front end. A steel shank being fitted into the bore of the bolster at a bolster end of the shank, and a portion of the shank is disposed within a bore of the holder at a holder end of the shank.

In one aspect of the present invention, a high impact resistant excavation pick having a super hard material is bonded to a cemented metal carbide substrate at a non-planar interface. The cemented metal carbide substrate is bonded to a front end of a cemented metal carbide frustum. A tapered bore is formed in the base end of the carbide frustum opposite the front end and a steel shank with a tapered interface is fitted into the tapered bore.

A New Phosphor-converted LED Device (“NPCLD”) is disclosed. The NPCLD may include a lens over a phosphor body, in which the lens and the phosphor body each have a substantially convex upper surface. The NPCLD may alternatively include first and second lenses, the first lens having a substantially flat interface with a phosphor body.

A high-impact resistant pick having a superhard material bonded to a cemented metal carbide substrate at a non-planar interface. The cemented metal carbide substrate is bonded to a front end of a cemented metal carbide bolster. A bore formed in a base end of the carbide bolster is generally opposed to the front end. A steel body has a shaft extending distally from a shelf, and which shaft is fitted into the bore of the bolster at an interface. A shank adapted for connection to a driving mechanism extends proximally from the steel body opposite the shaft. A washer is disposed intermediate the base end of the carbide bolster and the shelf of the steel body.

An impact tool for use with a driving mechanism, the impact tool including an impact tip formed from a super hard material and having an apex and an attachment end, with the attachment end being bonded to a cemented metal carbide substrate at a non-planar interface. The cemented metal carbide substrate is bonded in turn to the front end of a cemented metal carbide bolster. The carbide bolster is securable against an outer surface of a driving mechanism through a press fit.

Insulating packaging material is wrapped or otherwise positioned around the typically temperature sensitive product, with the packing material including, alternatively, 1 ply (FIG. 22; metallized plastic film), 2 ply (FIGS. 23 & 24) and 3 ply (FIG. 25) material, in which some of the 2 ply & 3 ply embodiments include a layer of bubble wrap material having its bubble side placed or laminated against the flat side of the adjacent ply, which adjacent ply can be, for example, a mettalized plastic film or a foam layer or both layers can be included. With such a bubble side arrangement, multitudinous air pockets are formed between the bubbles of the bubble wrap and the other ply's typically flat interfacing surface. A separate layer of bubble wrap also preferably is placed about the interior of the box with its bubble side placed against the interior flat surfaces of the box, with the bubbles forming air pockets with the flat sides, further enhancing the insulating properties of the packaging for the goods. An exemplary system for delivering perishable groceries (120 / 120'), including a corrugated cardboard or other type box (100); a source of cold (or heat as needed) maintaining the temperature inside the box within a desired temperature range for hours or days, using an all encompassing pouch of packet material (110 / 10), used individually (FIGS. 2 & 3) or collectively (FIGS. 5 & 6), with each packet (17) containing a super-absorbent polymer (14, FIG. 12) which is hydrated (14', FIG. 12A) and then either frozen (e.g., in a freezer) or heated (e.g., in a microwave), without producing moisture as the polymer returns to its natural state; a protective cover (130) protecting the box and its contents from heat radiation (e.g., sunlight).
