Abstract: Techniques for improving implementation of a downhole tool string to be deployed in a borehole formed in a sub-surface formation. In some embodiments, a design device determines a model that describes expected relationship between properties of the downhole tool string, the borehole, the sub-surface formation, and mud cake expected to be formed in the borehole; determines calibration locations along the borehole based on properties of the borehole; determines candidate spacer configurations based on contact force expected to occur at contact points between the downhole tool string and the mud cake when deployed with each of the candidate spacer configuration via the model; and determines a final spacer configuration to be used to attach one or more spacers along the downhole tool string based on expected head tension to move the downhole tool string when deployed in the borehole with each of the candidate spacer configurations via the model.

Abstract: A manufacturing system that manufactures a downhole tool string, which includes a model that describes relationship between properties of the downhole tool string, properties of a borehole, properties of a formation, and properties of a mud cake formed on a surface of the borehole and a design device that iteratively determines contact parameters that describe one or more contact points expected between the downhole tool string and the mud cake based at least in part on the model, in which the contact parameters comprise contact force expected at each of the contact points, adjusts the properties of the downhole tool string to add a spacer at one of the contact points associated with highest contact force, and indicates location, type, or both of the spacer to enable the manufacturing system to attach the spacer to the downhole tool string before deployment of the downhole tool string in the borehole.

Abstract: Apparatus and methods for aggregating work activity information, application usage and/or self-reported work status designations are presented. Tracked activity information can be used to automatically determine worker status, or audit status designations manually submitted by workers. Reporting can be delivered to users (a) tracking activities and progress against predetermined objectives, and/or (b) comparing worker activities and progress against that of other workers. Worker activity information can be used by managers to evaluate and improve worker performance.

Abstract: The present invention provides a leveling control system for a forestry machine (10) employing position sensors that relay information about the orientation of the carriage (12) in relation to the swing-house assembly (14) in order to control roll and pitch in a manner that maximizes the operating envelop of the leveling mechanism (38). The angles of pitch and roll of the swing-house assembly (14) in relation to the carriage (12) are measured and/or calculated and a controller (24) limits operation of the leveling mechanism (38) to an operating envelop that may be described in terms of pitch and droll. The cylinders (54, 56) are decelerated gradually as the operating envelop is approached. The controller (24) can include an automatic leveling mode. The controller (24) can change the function of the fore, aft, left and right operator controls so that they are true from the operator's frame of reference regardless of the rotary position of the cab relative to the carriage (12).

Abstract: An improved suspension apparatus and method for damping vibration arising in liquid vortex mixers of the type pivotably supporting a mixing frame assembly and suspending the assembly by at least one spring for mixing a liquid coating using both spin and orbital rotational movements. A pivoting support is located between the mixing frame assembly and a base. A damper in the form of an annular ring is used to damp pivoting movement of the mixing frame assembly. Various pivoting mounts may be used to pivotably support the mixing frame on a base. A bushing provides accommodation of a misaligned spring mounting end turn using a V-groove to retain the spring mounting end turn, and may include an eccentric feature to allow adjustment of the spring mounting length.

Abstract: An improved apparatus and method for balancing paint mixers including pivotably supporting a mixing frame assembly and suspending the assembly by at least one spring for mixing a liquid coating using both spin and orbital rotational movements and adjusting the lowest rotational resonant frequencies of the mixing frame assembly to be substantially below the lower of a pair of forcing function frequencies corresponding to the spin and orbit velocities. Optionally one or more dampers may be used to damp pivoting movement of the mixing frame assembly.

Abstract: Apparatus and method for automatically determining which of at least two forces to apply to a paint container in a mixing apparatus that is capable of clamping various sized paint containers. A clamp motor drives a clamping apparatus toward a paint container and a current rise signals engagement of the clamp with the container, whereupon a selection is made from a predetermined set of forces to apply to the container based on the time of energization and voltage applied to the clamp motor.

Abstract: A process for increasing or reducing the internal pressure of at least one hollow body (HK—1, HK—2, HK—3) to a specified set internal pressure. The set internal pressure is adjusted so that several pressure-increasing steps or pressure-reducing steps are conducted successively until the internal pressure deviates from the set internal pressure at most by a specified tolerance. Each of these steps brings about a pressure increase or pressure reduction the amount of which is not larger than a specified upper limit. In this way, impairments of comfort owing to the rise in pressure or the reduction in pressure are especially avoided. The actual internal pressure is only measured at the beginning of the process. In one design of the invention, this amount depends upon the volumes of the hollow bodies (HK—1, HK—2, HK—3) and a supply line (VL) as well as (in the case pressure is increased) from the pressure which a pressure generator generates.

According to the invention, an extruder head (50) is provided for use in a device for the coating of a conductor or a conductor line (72), having at least one extruder die (56), which is connected on one side to a supply conduit (58) for feeding the coating material. On the other side, the extruder die (56) opens out into into a region to which the conductor that is to be coated or the conductor line that is to be coated is adjacent during operation. Furthermore, the outlet of the extruder die (56) can be closed by means of a seal (57).

Abstract: The insulating duct (6) is formed by a material which is built up in layers and is shaped in the manner of an L. The base of the L, which serves as the duct bottom (8), is of rigid design, whereas that limb of the L which serves as the duct wall (11) is of flexible design. A reinforcing insert (12, 13) is placed into the duct bottom (10, 11) and is guided into that part of the duct wall (10, 11) which adjoins the duct bottom (7, 8). In a U-shaped slot-insulating means formed from two of these insulating ducts (6) the radii located at the transitions between the base and the limbs of the U then exhibit great strength. During operation of a rotating, electrical machine into whose rotor a slot-insulating means produced in such a manner has been inserted, migration of the slot-insulating means because of centrifugal forces is very reliably avoided.
