摘要： A process for forming a liquid-solid composition from a material which, when frozen from its liquid state without agitation, forms a dendritic structure. A material having a non-thioxotropic-type structure, in a solid form, is fed into an extruder. The material is heated to a temperature above its liquidus temperature. It is then cooled to a temperature less than its liquidus temperature and greater than its solidus temperature, while being subjected to sufficient shearing action to break at least a portion of the dendritic structures as they form. Thereafter, the material is fed out of the extruder.

摘要： A dosed amount of molding sand is placed in a vessel arranged at a given distance from a pattern device from which a mold is to be formed, and a pressurized force is applied against the molding sand in the vessel from the side thereof remote from the pattern device in order thereby to impart to the molding sand an acceleration in the direction of the pattern device to compress the sand about the pattern device with the velocity of the accelerated molding sand being braked by impact with the pattern device and also by impact partially with a molding box within which the pattern device is contained. The vessel containing the molding sand is connected to a pressure source by a valve device which controls the application of pressure to the molding sand. Additionally a vacuum device is utilized to apply suction tending to compact the sand within the vessel to produce a more cohesive mass. After the vessel and the pattern device are moved into operative position, and the suction has been terminated, the valve may be opened to apply a pressurized force propelling the sand from the vessel against the pattern device.
摘要翻译：将一定量的型砂放置在与要形成模具的图案装置相隔给定距离的容器中，并且从其远离图案的一侧向容器中的型砂施加加压力装置，从而赋予型砂在图案装置的方向上的加速度，以通过与图案装置冲击而制成的加速型砂的速度以及部分地与成型箱，其中包含图案装置。容纳型砂的容器通过控制向型砂施加压力的阀装置连接到压力源。此外，使用真空装置来施加吸力，以压缩容器内的沙子以产生更加内聚的物质。在容器和图案装置移动到操作位置并且抽吸已经终止之后，可以打开阀门以施加加压力，该压力迫使来自容器的砂子抵靠图案装置。

摘要： A system for automatically assembling flaskless copes and drags, preparing them for metal pouring on an indexing conveyor belt. A cope is centered on the conveyor, lifted, and rotated 180.degree.. Thereafter, a drag is centered beneath the cope, and the cope is lowered onto the drag, to form a complete mold, ready for metal pouring. All of the above is accomplished automatically, with little or no supervision required.

摘要： A roll-over transfer for foundry equipment is disclosed in which a "C" shaped frame rolls along a base combining translation and rotation between two end positions. The frame is powered by piston and cylinder actuator connected for a cycloidal operation to provide maximum acceleration and deceleration at the ends of the frame travel. Cables are connected between the frame and base to maintain a predetermined relationship between the translating movement and the rotating movement. Primary and supplemental stops cooperate to positively prevent over-travel in the event of a failure in the drive system. A single clamp and draw actuator is centrally mounted on the frame for clamping and drawing foundry equipment. The machine is flexible in use in that it can be loaded and unloaded from any one of three directions in each of its operated positions.

摘要： A foundry equipment comprises at least one guiding track element on which a number of identical mould parts are successively piled together in a position in which their greatest dimension is horizontal. After the formation of the mould, the guiding track element with the mould thereon is tilted about 90.degree. around a horizontal axis that is parallel to the longitudinal direction of the mould, thus bringing the mould into a position in which it is ready for the pouring operation.

摘要： Modified cellulosic fibers, characterized by improved properties, such as reduced swellability and reduced natural fiber-to-fiber bonding, are produced by a process which comprises treating an aqueous slurry of the fibers with a substantive polymeric compound, drying the treated fibers to cause the polymeric compound to react with itself and with the fibers, and refiberizing in water to separate the individual, treated fibers. The fibers are useful in the preparation of improved cellulosic sheet materials which exhibit increased bulk and reduced tensile strength.

摘要： TWISTED, FLEXIBLE, MODIFIED, CELLULOSIC FIBERS WHICH EXHIBIT IMPROVED PROPERTIES, SUCH AS REDUCED SWELLABILITY, COMPRISE WOOD PULP FIBERS COATED WITH A SUBSTANTIVE POLYMERIC COMPOUND. THE ABOVE-MENTIONED FIBERS ARE PRODUCED BY A THREE-STEP PROCESS WHICH COMPRISES TREATING AN AQUEOUS SLURRY OF THE CELLULOSIC FIBERS WITH A SUBSTANTIVE POLYMERIC COMPOUND, DRYING THE TREATED FIBERS TO CAUSE THE POLYMERIC COMPOUND TO REACT WITH ITSELF AND WITH THE FIBERS UNDER CONDTIONS WHEREIN THE FIBERS ARE RELATIVELY FREE FROM CONTACT WITH ONE ANOTHER, AND REFIBERIZING THE TREATED AND DRIED FIBERS UNDER DRY CONTITIONS TO SEPARATE INDIVIDUAL MODIFIED FIBERS. THE MODIFIED FIBERS ARE USEFUL IN THE PREPARATION OF COHERENT, DRYFORMED WEBS HAVING IMPROVED PROPERTIES, SUCH AS ENHANCED WET AND DRY RESILIENCY, INCREASED BREAKING LENGTH, AND IMPROVED SHAPE RETENTION WHEN EITHER WET OR DRY.
