摘要:
A computerized system for augmenting data from a source database with data from a reference database to generate an augmented database that can be used for predictive modeling is disclosed. The present invention includes a method for using the Internet to obtain information, including, reading a data record stored in a field of data, searching a database for information describing the data record, condensing the information describing the data record into a value description, associating the value description with the data record, and augmenting the field of data with the value description associated with the data. The present invention also includes a computerized system for augmenting data from a source database with data from a reference database to generate an augmented database that can be used for predictive modeling and data mining to conduct searches of data in the augmented database.

A drum dryer for use in the manufacture of bituminous concrete asphalt is provided with a jacket including a layer of ceramic fiber insulation bonded to an outer sheath of aluminum, the jacket being wrapped around the outer peripheral surface of the wall of the drum and secured in place with bands of stainless steel strapping so as to reduce to a minimum heat loss due to dissipation of heat from the outer peripheral surface of the drum wall, thereby enabling conservation of energy, while affording protection to personnel and equipment in the vicinity of the dryer drum against excessive heat.
摘要:
Asphalt mix product is produced for delivery at a desired temperature and is comprised of a mixture of recycled asphalt product and virgin material in a specified, selected proportion of recycled asphalt product to virgin material. Recycled asphalt product is heated in an indirectly heated recycled asphalt product heater to an elevated temperature. Virgin material is heated in a heater to a maximum temperature not exceeding a prescribed temperature above which damage to that heater will occur. The heated recycled asphalt product is mixed with the heated virgin material in the selected proportion of recycled asphalt product to virgin material to prepare the asphalt mix product for delivery at the desired temperature. By virtue of heating the recycled asphalt product and mixing the heated recycled asphalt product with the heated virgin material, the selected proportion of recycled asphalt product to virgin material is not limited by the maximum temperature of the heated virgin material, and asphalt mix product is produced effectively and economically with proportions of recycled asphalt product to virgin material which are considerably higher than heretofore available.
摘要:
An indexable shell cutter having an improved cartridge for mounting a cutter insert on the cutting face of the shell cutter body. The cutter body has a plurality of recesses extending rearwardly from the cutting face, each of said recesses being formed by a first surface, a second surface spaced from the first surface, and a base surface extending between the first and second surfaces. The second surface is essentially perpendicular to the plane of the cutting face of the cutter head and is V-shaped in cross-section. A cartridge is removably secured in each of the recesses with the base of the cartridge being in mating engagement with the second surface of the recess. A replaceable and indexable cutter insert having a plurality of cutting edges is releasably secured in a recessed seat located in the outer end of each cartridge with the plane of its face being perpendicular to the plane of the cutting face of the cutter head and one of its cutting edges extending beyond the periphery of a cutting head a distance sufficient to cuttingly engage a workpiece. The other cutting edges of the cutter insert are matingly engaged with the walls of a recessed seat formed in the outer face of the cartridge.

Apparatus and method for processing asphalt material to be recycled by introducing used asphalt material from the field in relatively large pieces, as received from the field, into one end of a cage-like array of tubular breaker members while simultaneously heating the tubular breaker members from the other end of the cage-like array and rotating the cage-like array about a tilted central axis of rotation to tumble the material within the cage-like array and reduce the size of the pieces of material to a desired aggregate size within a mass of material moving toward the other end of the cage-like array, the tubular breaker members being spaced apart circumferentially such that only the desired aggregate-sized pieces in the mass of material pass radially out of the cage-like array for delivery and reuse.
摘要:
Recycled asphalt product is heated within an indirectly heated recycled asphalt product heater by passing heated gases through heat exchange members within a drum while the recycled asphalt product is moved through the drum from one end to the other end of the drum. The heat exchange members provide conduits for the heated gases, the conduits extending from an inlet adjacent a source of heated gases to an outlet communicating with an exhaust, each conduit following a looped path and having two or more segments each with a longitudinal length extending from adjacent one end of the drum to adjacent the other end of the drum. The segments are arranged serially in a serpentine configuration, are generally parallel to one another, and are spaced apart radially within the interior of the drum. Each inlet is coupled with the source of heated gases for longitudinal movement of the inlet relative to the drum along an inlet site adjacent the source of heated gases, and each outlet is connected to the drum for affixing the outlet against longitudinal movement relative to the drum at an outlet site adjacent one of the ends of the drum. The configuration and orientation of the conduits enable longitudinal expansion and contraction of the conduits in response to heating and cooling of the conduits, while the outlets remain essentially stationary at the outlet site.

Apparatus for processing recyclable asphalt material includes an elongate drum having a generally cylindrical wall, a central axis, a first end and a second end, and being mounted for rotation about the central axis, with the central axis tilted at an acute angle so as to elevate one of the first and second ends relative to the other of the first and second ends, a heating chamber adjacent the first end of the drum, a plurality of breaker members arrayed generally parallel to the central axis of the drum and placed within the drum, a heat conduit extending along the drum coaxial with the breaker members, a heating arrangement for supplying heat to the heating chamber, ducting interconnecting the heating chamber, the breaker members, and the heat conduit serially such that heat from the heating chamber is conducted from adjacent the first end of the drum to adjacent the second end of the drum and is returned to adjacent the first end of the drum serially through the breaker members and the heat conduit, a feed arrangement for feeding the recyclable asphalt material into the drum, adjacent the elevated one of the first and second ends of the drum, and a rotational drive for rotating the drum, the breaker members and the heat conduit about the central axis so as to tumble the recyclable asphalt material within the drum, against the breaker members and against the heat conduit to process and deliver the desired recycled asphalt material adjacent the other of the first and second ends of the drum.
