Title: Riser topping gathering system and method
Inventor: SMORYNSKI MICHAEL E
IPC: B22D29/00
Filed: 2001-05-04
Abstract: A riser topping gathering system and method are disclosed. The system and method are used in gathering riser topping material from the riser cavities of the cope portion of a mold. A capture hood includes high-pressure air outlets and is connected to a duct system, collector and air moving mechanism. The capture hood is moved into contact with the top of the cope mold portion. The air moving mechanism pulls a stream of ambient air over the top of the cope mold portion while high pressure air is pulsed into the riser cavities through the high air pressure outlets. The pulses of high-pressure air activate the riser topping materials and raise them out of the riser cavities and into the path of the ambient air in the capture hood.  The moving ambient air carries the riser topping material out of the capture hood and into the duct system. The air and riser topping material is moved to the collector where the riser topping material is separated from the air. The riser topping material may then be gathered from the collector and disposed of or recycled. The cope mold portion may then be moved to another workstation for removal of the risers from the riser cavities.

Abstract: A heating system for heating liquids, stored in a tank at low ambient temperature, has a heating chamber with an inlet and an outlet for convectively flowing liquid past a flameless heater. Cold liquid is drawn through an inlet line, from the tank near its base and into a heating chamber, absorbs radiant energy from the heater as it travels therethrough. Heated liquid is circulated into the tank through an upper outlet from the heating chamber and back into the tank. Preferably, the heated liquid reenters the tank through a floating discharge flexibly connected to the upper outlet so as to remain dynamically in contact with the liquid at all times, thus avoiding airlocks which would interrupt the convective flow of liquid through the heating system.

Abstract: Thermally formed thermoplastic articles can be protected from stress cracking in the presence of stress cracking promoting compounds by forming a shaped article comprising a thermoplastic and a liquid hydrocarbon oil composition. We have found that the liquid hydrocarbon oil composition prevents the stress cracking promoting materials from interacting with the polymeric structure of the stressed container to prevent or inhibit stress cracking in such materials. The methods and compositions of the invention are particularly useful in preventing stress cracking in polyethylene terephthalate beverage containers during bottling operations during which the bottle is contacted with aqueous and non-aqueous materials such as cleaners and lubricants that can interact with the polyester to cause stress cracking particularly in the container base. A process for lubricating a container, such as a beverage container, or a conveyor for containers, by applying to the container or conveyor, a thin continuous, substantially non-dripping layer of a liquid lubricant. The process provides many advantages compared to the use of a conventional dilute aqueous lubricant.

Abstract: A lead alloy for lead. acid-battery grids which essentially consists of about 0.05-0.07 wt calcium; about 0.09-1.3 wt% tin; about 0.006-0.010%silver; about 0.0100-0.0170 wt% barium and about 0.015-0.025 wt% aluminum with the balance lead. This lead alloy allows the improvement of the age hardening step; by eliminating the high temperature treatment process required for silver alloys in the manufacturing of lead-acid batteries. By using this lead alloy, a longer service life of the lead-acid batteries are also obtained by increasing the corrosion resistance and the mechanical strength of battery grids manufactured by the book molding process.  Additionally, the reduced silver level used dramatically mitigates the problem of silver elimination from the stream of recycled lead in the secondary production of this metal.

Abstract: A rotating modular arm with two arm segments is used in a cabinet locking system. The two arm segments are urged apart by a spring. Each arm segment is connected to a lock bar. When the modular arm is rotated, the arm segments displace the lock bars to lock or unlock the drawers of the cabinet. One of the arm segments defines an elongated asymmetrical slot with two slot portions. The first slot portion is elongated and has a width that is less than the diameter of the second slot portion. A keyed lock housing includes a rotating lock core attached to a Z-shaped crank. A retainer is securely attached to the crank. The retainer has a diameter that is less than the diameter of the second slot portion, but the retainer diameter is greater than the width of the first slot portion. During installation, the retainer is engaged with the modular arm by first inserting the crank through the second slot portion. The crank is then displaced to engage the crank with the first slot portion so that rotation of the lock core will turn the crank and rotate the modular arm to displace the lock bars. A clip is not required to secure the crank to the modular arm. The two arm segments are connected with a releasable detent. A spring mounted on the exterior of one of the arm segments is used to urge the arms apart.
