Abstract:
A plasticating extruder screw conveyor includes multiple primary flights and corresponding multiple secondary flights defining multiple channels on the screw conveyor arranged about the longitudinal axis of the screw conveyor such that radial components of forces between the screw conveyor and unplasticated material located in the channels are substantially balanced so as to reduce to a minimum any resultant radial force upon the screw conveyor and any concomitant lateral deflection of the screw conveyor, thereby reducing or eliminating excessive vibration, wear or galling of the screw conveyor.
Abstract:
A cross-head die in which the manifold is provided with means for selectively varying the volume of the manifold at some locations relative to other locations, whereby the relative wall thickness about the annular configuration of the material flowing through the die is selectively adjusted about the periphery of the annular configuration of flowing material. Wall thickness and configuration are further controlled at the outlet orifice of the die by means movable to selectively expand, contract and alter the annular configuration of the die passage at the orifice.
Abstract:
A plasticating apparatus operates continuously to plasticate material which is delivered intermittently to a molding device, the plasticating apparatus including a first screw conveyor which rotates in a barrel, a backfeed passage within the first screw conveyor and a second screw conveyor in the backfeed passage arranged to recirculate material in a circuit extending back through the backfeed passage. The first screw conveyor reciprocates axially so that during periods of non-delivery of plasticated material, the capacity of the circuit is increased to accommodate the accumulation of added plasticated material generated by the continuous rotation of the first screw conveyor.
Abstract:
Method and apparatus in which a selected coating is applied to specific surfaces within a plasticating extruder to change the coefficient of friction between the solids being conveyed in the extruder and the specific surfaces in such a way as to improve solids conveying and thereby increase the production effectiveness of the extruder.
Abstract:
Apparatus and method in which the temperature of the barrel inner surface and the temperature of the screw conveyor outer surface of a plasticating extruder are varied, alternately, in repeated steps, independent of one another along at least a portion of the solids conveying zone of the extruder, while a production effectiveness parameter simultaneously is monitored, until the monitored production effectiveness parameter is optimized and the production effectiveness of the extruder is at a desired maximum.
Abstract:
A plasticating extruder in which the screw conveyor includes an inner backfeed passage communicating with the channel established by the main flight of the screw conveyor and a solids-directing flight for directing unplasticated material into the backfeed passage and segregating already-plasticated material from the unplasticated material in the channel.
Abstract:
A system that incorporates teachings of the present disclosure may include, for example, a server having a memory coupled to a processor. The processor can be operable to receive a request for promotional information responsive to a media processor detecting a promotional tag in a media program stream and transmit to the media processor promotional information associated with a promotion responsive to a determination that a promotional offer is available. The processor can also be operable to receive from the media processor a request for redeemable material associated with the promotion and store the redeemable material in a portion of a database associated with a user of the media processor. Other embodiments are disclosed.
Abstract:
Concepts and technologies are disclosed herein for providing, storing, redeeming, and managing promotions. A promotion service can be called to save, manage, or redeem promotions. The promotion service can be called to generate or provide promotions based upon contextual information. The promotion service also can be accessed to save promotions as well as to view or redeem saved promotions. In some implementations, the promotions can be stored in a promotion locker or other data storage device that is accessible to the promotion service. Promotions can be redeemed at a point of sale such as a web site or a physical retailer. In one contemplated embodiment, a user accesses the promotion service via a smart phone, and a bar code or other information associated with the promotion is displayed on the smart phone in response to a user request.
