摘要:
The present invention involves a sampler designed to collect drill cuttings which are produced during drilling of a blast hole in open-pit mining operations. The present invention is designed to capture a theoretically accurate sample which will be assayed for the gold and silver it contains (and may be appropriate for other minerals as well). The present invention obtains a larger, more representative sample and has the ability to split the sample automatically to a reasonable lab delivery weight. The design of the invention provides for sampling through the drill deck of drill machines which are commonly used in open-pit mining operations. The design of the invention allows for sampling over the entire particle trajectory and is unaffected by changes in drilling equipment. The sampler comprises a pan which is tapered and receives drill cuttings produced from drilling a blast hole. The sampler may also comprise a rear arm which is pivotally connected near the back wall of the pan, and a front arm which is pivotally connected to the pan at a location farther from the back wall of the pan relative to the rear arm.

Improved insulative cable assemblies and methods for producing them are disclosed. The insulative cable assemblies have a conductor housed within a polymeric insulation layer expanded with expandable thermoplastic microspheres. The use of a relatively inelastic outside sheath controls the expansion of the insulative layer and assures a snug fit between the insulation and the conductor. The insulation layer is highly resilient and resistant to dielectric changes due to compression or damage from mechanical manipulation of the cable. Additionally, the ability to expand the insulative layer after cable assembly is completed provides far greater freedom in cable processing without compromising low dielectric constant.

Single pellets of a thermoplastic resin containing long glass fibers and a conductive filler are set forth that enable molded articles made from these pellets to exhibit conductivity and, at the same time, high mechanical properties. These pellets have mechanical properties that are substantially equivalent to non-conductive pellets of a thermoplastic resin containing same loading of long glass and provide conductivity that is substantially equivalent to articles obtained by blending two kinds of pellets, one pellet having a conductive filler and the other pellet one containing long glass fibers. The pellets include a thermoplastic resin, a long fiber reinforcing filler and a conductive additive dispersed in the pellet.

Tools providing a flexible selection framework for automated processes. The framework can allow end-users to define their own selection criteria to select a data population to be processed (for example, by a business application). Hence, the tools provide enhanced control over what data is provided to which process. Some such tools employ metadata to define what information the client process needs, how the results will be returned to the client process, and/or what selection tools should be available to select data for the client process, as well as the available data selection tools, which can include both tools provided with a business application as well as third-party and/or user supplied selection tools. The framework might also provide an application programming interface that ensures consistent communication between the population selection engine and the selection tools themselves.

In an automated prescription dispensing and packing system, empty prescription bottles are labeled and loaded in assigned locations in carriers. Pills are automatically dispensed into the prescription bottles in the carriers. Ranks of carriers containing filled prescription bottles are assembled at stations where the bottles are unloaded and packed into shipping containers with literature printed by the system. Multiple bottles of an order are automatically packed in the same shipping container.

A product design method includes accessing a defined product design structure. The product design structure includes a number of customer concerns, a number of physical properties associated with components of the product, and a number of relation models. Each customer concern is associated with at least one physical property via at least one mathematical relationship defined in at least one of the relation models. The method also includes receiving a value associated with one or more of the physical properties and calculating (using one or more of the relation models) the effect of the received value associated with the one or more physical properties on one or more of the customer concerns. Furthermore, the method includes displaying the calculated effect on the one or more customer concerns and receiving one or more adjustments of the value associated with one or more of the physical properties to create a desired effect on one or more of the customer concerns.

An active fluid bearing system is provided. In one example, the active fluid bearing system includes an interface region formed between an outer surface of an inner member and an opposing inner surface of an outer member. The inner and outer members are disposed for relative rotation of the inner and outer members, and thereby form an interface region having a hydrodynamic bearing region and an active bearing region. A liquid is disposed in the interface region at the hydrodynamic bearing region, and is further disposed in the active bearing region if the inner and outer members are not relatively rotating. The bearing system is operable for evacuating at least a portion of the liquid from the active bearing region during relative rotation of the inner and outer members. The active bearing region may be a journal bearing or a thrust bearing.

In one particular embodiment, the disclosure is directed to a conveyor belt including a set of warp knitted yarns configured in warp-oriented wales and a set of weft insert yarns inserted in the set of warp-oriented wales. The set of weft insert yarns have a cross-sectional aspect ratio at least about 2:1.

A blower housing may be used with a climate control furnace or with a water heater and provides cooling of the motor that rotates the blower fan and also provides dilution and cooling of exhaust gases drawn from the furnace or water heater. The housing is constructed with one side that is positioned in a single plane that is easily mounted to a flat surface of the furnace or water heater and can be sealed against the surface. The housing is provided with an interior heat shield that insulates the exterior surface of the housing and with a noise muffler.
