Abstract: The invention relates to a kibble tipping arrangement, which is used in a mining operation where a kibble (12) is vertically displaceable along a kibble displacement path to transport excavated material is a vertical mine shaft to the surface. The kibble tipping arrangement includes at least one catch (24) which is transversely displaceable between a non-interference position in which the catch does not interfere with the kibble (12) in the kibble displacement path and an interference position in which the catch (24) is capable of being engaged by an engagement formation (28) on the kibble (12) to allow the kibble (12) to top and the excavated material to be dumped from the kibble (12). The kibble tipping arrangement further includes kibble alignment means, which consist of a locator and a positioner, for aligning the kibble's engagement formation (28) with the catch (24).

Abstract: A method for coordinating medical treatments and in-care patient tracking system is set forth wherein a patient peripheral enables determination of patient location data, patient identification data, and treatment data, by sensed spatiotemporal relationships of the patient peripheral within a designated area. Proximity of the patient peripheral with a practitioner peripheral enables automated association of treatment data to a patient record alongside practitioner identification data. Treatment data generated, such as collected samples and other data, effects automatic assignment of the patient identity to relevant data and materials. Inventory is trackable, and doses administered are reportable automatically to the patient record.

Abstract: An integrated circuit comprises a main bus, one or more integrated processors, an external bus interface, memory, internal bus controller, a signal analyzer, timers, reset/clock generator, radio controller, optional data converters, and optional radio. The signal analyzer performs both time-domain and frequency-domain analysis of the input signal and supplies data to the one or more integrated processors for signal classification.

Abstract: The following invention is directed to macromolecules having controlled stoichiometry and topology, processes for their production, and applications for their use. The macromolecules have a controlled functional moiety stoichiometry and include at least one dendritic motif having a surface layer formed from at least one surface building unit and at least one subsurface layer formed from at least one building unit, the surface building unit and building units having a hydrocarbon backbone bearing a carbonyl group and at least one amine group; and at least two different functional moieties on the building unit and/or surface building unit; where functional moiety stoichiometry refers to the number and type of functional moieties.

Abstract: A variable torque-rate test point for the performance testing of rotary tools for threaded fasteners comprises a screw-threaded bolt (1) having a moment of inertia comparable to that of a bolt to be tightened using the rotary tool. The bolt (1) is tightened in the test joint against a torque-rate adjustment device (6) which can be adjusted to simulate a hard or a soft joint. The adjustment device (6) comprises a washer portion (7) beneath the bolt head (4), at least one spring beam (8) extending from a reaction point (9) radially outwardly of the bolt (1), and a pivotal bearing member (10) or other pivot at a mid portion of the beam (8). The beam (8) flexes as it extends in cantilever over the pivot point, and that flexure can be adjusted to vary the torque-rate of the test joint by varying the distance between the pivot point and the rotary axis of the bolt (1).

Abstract: An approach for selecting communications channels to be used by a communication system includes evaluating for the presence of one or more signals both a particular communications channel currently being used by the communication system and one or more other communications channels. For the particular communications channel currently being used by the communication system, signals that use a different communications protocol than the communication system are evaluated. For the one or more other communications channels, both signals that use the same communications protocol as the communication system and signals that use a different communications protocol than the communication system are evaluated. The approach may include the use of metrics and classification of device types to determine one or more communications channels to be used by the communication system.

Abstract: A securing arrangement 32 for securing an actuating lever 20 to a spindle 14, for example a spindle 14 of a variable inlet guide vane 10 in a gas turbine engine, comprises a fastening formation 38 rotatably co-operable, in use, with a corresponding fastening formation 30 on the spindle 14. The securing arrangement 32 is rotatable relative to the spindle 14 to a securing position in which the respective fastening formations 30, 38 co-operate so that the securing arrangement 32 secures the actuating lever 20 to the spindle 14. The securing arrangement 32 includes anti-rotation means 42, preferably in the form of anti-rotation tabs 44, for preventing rotation of the securing arrangement 32 from the securing position.
