Abstract: An explosion treatment apparatus useful for confined shock exposure of materials as for removal of sand cores from finished castings and, in particular, cores in permanent mold castings in which a horizontally axised index device successively presents plural and substantially similar cavities to a position at which sealing, evacuating, fueling and ignition occur. This results in an explosion which occurs upon closure of each chamber. After the confined explosion, the cavity is opened and all cavities are indexed so that the fired cavity can be unloaded, the previously unloaded cavity can be dumped, the next adjacent cavity can be reloaded, and the reloaded cavity is presented to closure.

Abstract: A continuous lubrication casting mold for use in a process of continuously casting molten metals and alloys wherein a parting and/or lubricating agent reservoir is provided in the mold body. The agent is continuously applied over the inner surface of the mold after being introduced through passages within or through the mold section. The lubricant passages may be an intrinsic characteristic of the mold material or may be provided in the form of feed holes through the mold section. The ability to transmit lubricant through to the internal surface of the mold can be varied within the length of the casting mold to provide for variable lubricant transfer rates to different parts of the casting surface.

Abstract: An animal trap comprises a base frame having an upper surface and a jaw member pivotally mounted on the base for pivotal movement from a cocked position to a sprung position, the jaw member having at least one horizontal bar extending transversely of the base. Spring means yieldably urge the jaw member to the sprung position. A catch member is pivotally mounted on the frame also and includes a catch pawl for retentively engaging the bar of the jaw member to hold the bar in its cocked position. The catch member is pivotal away from retentive engagement with the bar to release the jaw member so that it can return to its original position. A trip member is also pivotally mounted on the base, and is engageable with the catch member to hold the catch member against the bar when the bar is in its locked position. The trip member is movable to release the catch member which in turn releases the bar and permits the jaw member to pivot to its sprung position.

Abstract: The present invention is a shot making apparatus which allows rapid and reliable production of shot and which is relatively compact in size. The shot making apparatus comprises a receptacle for lead, at least one nozzle for discharging molten lead in droplet form from the receptacle, a heating means being disposed such as to heat the chute, a chute being disposed at a spacing from and at a downwardly inclined angle to the nozzle(s), and a container(s) for liquid coolant and lead droplets discharged from said nozzle(s).

Abstract: Steel powders are added to steel in a stream of inert gas introduced into the ladle above the casting mold, at a point near the exit of the steel from the ladle. The powders are thus entrained in the metal entering the mold and dissolve therein. The lance that injects the powders may also plug the ladle outlet. The powders can be used not only to perform their cooling function but also to introduce alloying elements.

Abstract: An improved method is utilized to make an improved mold for forming a plurality of small objects, such as piston rings. The mold is made by stacking a plurality of mold sections formed of gas permeable material, such as CO.sub.2 sand, resin bonded sand or green sand. The stacked mold sections are then clamped together to hold them against movement relative to each other. A wet coating of liquid ceramic material is then applied over the stack of mold sections. This liquid ceramic mold material is dried to form a rigid gas permeable ceramic casing which encloses the stack of mold sections. The rigid casing of ceramic material holds the mold sections against movement relative to each other to prevent break-out of metal from between the mold sections when a flow of molten metal is directed into the mold cavities. Due to the gas permeable construction of both the rigid ceramic casing and the mold sections, gas can readily escape from the mold as the molten metal enters the mold cavities.

Abstract: An improvement in continuous metal casting machines of the type having a pair of flexible, moving casting belts which revolve along endless paths for defining a casting region therebetween and moving side dams which revolve along with the casting belts for confining the cast strip, slab or bar laterally. The casting belts are individually supported by upper and lower carriage means. The machine is provided with sensors such as load cells for sensing the displacement forces existing between the upper and lower carriages at selected points along the path of belt travel, and for sensing the side pressures exerted upon the side dams by the cooling, solidifying metal. This sensing permits the maintenance of predetermined, desired contact pressures along the length of the solidifying metal to thereby improve the physical characteristics of the cast product.

Abstract: A method for the die casting of end rings and conductor bars in rotors employing a die casting machine having a compensator mechanism comprising a compensator sleeve and a compensator for reciprocal movement along a first axis. A coaxially movable die plate closes off one end of the compensator sleeve to form a die cavity for casting. A plurality of lamination stacks, each held together by a removable stacking pin, are stored on an inclined loading rack positioned laterally on one side of the compensator mechanism. A few of these stacks roll down inclined planes into the compensator sleeves. The compensator pushes the stacks forward into abutment with the die plate and a charge of molten material is injected into the die cavity. The die plate then moves axially away from the compensator and a retriever moves perpendicular to the first axis to an unload position between the compensator sleeve and die plate.

Abstract: A method and apparatus is disclosed for the high-speed production of foundry cores of the type in which a foundry aggregate is mixed with a curable binder, preferably an isocyanate or phenolic material, to form a core mixture which is carried within a hermetically sealed core box and is hardened by the introduction into the core box of a gaseous curing agent, preferably an amine. A positive displacement pump pumps a predetermined amount of liquid amine from a holding tank to a vaporizer where it is heated and completely vaporized. The vaporized curing agent is forced from the vaporizer by the introduction of an inert gas, preferably nitrogen, and the mixture of the inert gas and the vaporized curing agent is entrained in a low pressure air stream which carries it to the core box, thereby curing the core. After the core is cured, valves close to stop the flow of the low pressure air stream, the mixture of inert gas and curing agent to the low pressure air stream, and the flow of inert gas to the vaporizer.

Abstract: A trap for catching and destroying small flying gnats consists of two main components, namely, top and bottom transparent chambers. The top chamber is removably mounted in a spaced relationship on the bottom chamber. The bottom wall of the top chamber is formed with a large central opening defined by an externally threaded cylindrical sleeve which is engaged within a complementary-shaped internally threaded cylindrical sleeve which surrounds a large central opening formed in the top wall of the bottom chamber. A plurality of small holes are formed in the bottom wall of the top chamber and are spaced about the large central opening. A fermenting liquid which is attractive to gnats is contained in the bottom chamber. The odor of the liquid escapes through the small holes and attracts the gnats which fly into the top chamber through the small holes where they become trapped and subsequently die and fall into the liquid in the bottom chamber.
