Disclosed is a handle clamp for an exothermic mold. The clamp includes a pair of legs, each having a plurality of rods that are shaped to fit into engagement holes on sections of the mold. The rods of each leg engage with one section of the mold. Engagement brackets are rotatably disposed on one or more or the rods. The brackets each have a thumb bolt that can be extended toward a mold section connected with the clamp. When engaged with the mold section, the thumb bolt stabilizes the mold section on the handle. A detent mechanism is provided between the bracket and the leg of the handle. The detent mechanism releasably holds the bracket in one of a selected plurality of rotational positions with respect to the rod. By selecting different rotational positions for the brackets, the handle can be configured to engage with different configurations of mold. The thumb bolts that are biased toward the mold section by a spring. The bolts include a key that can be aligned or misaligned with a key slot on the bracket. By aligning the key with the key with the key slot, the bolt can be moved toward or away from the mold section under the biasing force of the spring. By misaligning the key and key slot, the bolt can be locked into engagement with the mold section or else held in a disengaged position.

A food cooking appliance includes a panel having a thermal inertia, and a heater to heat the panel from the bottom face thereof. The panel has at least two plates that lie on top of each other. Plates are made of different materials and are in close contact with one another across part of the facing surfaces thereof. The upper plate being suitable to receive the food to be cooked, and is made of stainless steel or titanium. The lower plate is made of cast iron. A method for manufacturing a panel consisting of two metal plates that are made of different materials and are bonded together in a metal casting process.

A powder metal alloy composition is used in the production of a sintered powder metal insert for casting into an aluminum casting. The powder metal alloy composition includes an iron powder metal base, copper such that the copper is 3.5 weight percent or more of the powder metal alloy composition, and carbon in an amount of 0.1 to 1.0 weight percent of the powder metal alloy composition. Upon compacting and sintering the powder metal alloy composition to form the sintered powder metal insert, the sintered powder metal insert has a copper gradient that provides a higher concentration of copper on the surface of the sintered powder metal insert than in a center of the grains of the sintered powder metal insert. The higher concentration of copper at the surface of the insert enables a strong metallurgical bond to be formed with the aluminum casting during casting.

A crankshaft for an internal combustion engine is provided. The crankshaft comprises at least four main journals aligned on a crankshaft axis of rotation defining a centerline. The crankshaft further comprises at least three pin journals. Each pin journal is disposed about a respective pin journal axis and positioned between the main journals. Each of the pin journals is joined to a pair of crank arms. Each pair of crank arms is joined to a respective main journal. Each of the main journals, pin journals, and crank arms is made of a first metallic material. Each crank arm has an over-molded counterweight metallurgically bonded thereto. Each counterweight is disposed opposite a respective pin journal relative to the centerline for balance and stability. Each counterweight is made of a second metallic material. The crankshaft has a weight ratio of the second metallic material to the first metallic material of between 0.20 to 0.50.
