摘要： A method and apparatus for verification of the linear position of a machine element driven by a motor is provided. The actual position of the element is detected and compared to an expected position. When the two positions differ from each other by more than a predetermined tolerance value for a predetermined amount of time, an error signal is generated which deactivates the motor and generates an alarm for the machine operator. Preferably, the linear position of the axis is detected by a transducer and the expected position is determined by detecting the rotary position of the motor through the use of a resolver, which is then converted to a linear equivalent through the use of the gearing ratio. The method and apparatus can detect faulty machine conditions and thereby prevent machine malfunction and/or machine damage. Preferably, the method and apparatus are used to verify the position of machine elements in an injection molding machine.

摘要： A method and apparatus for measuring a misting property of fluids, the method and apparatus simulating mist generation of fluids in machining processes. Fluid is supplied to mist generating means in an enclosure and energy input to the fluid by the mist generating means is controlled. Mist laden gas flows from the vicinity of mist generation to a mist concentration measuring means. Droplets of relatively large mass are removed from the mist prior to the flow of gas reaching the mist concentration measuring means. To further simulate machining processes, the fluid of interest is recirculated from a reservoir through the mist generating means. Mist concentration measurements produced under the same conditions for fluids of different compositions are compared to characterize the misting properties of fluids.

摘要： Grinding and regulating wheels are carried on opposed feed slides on a machine base. A workrest is fixed to the base between the opposed wheels. Wheel dressers are mounted to cross-slides on the base, behind the wheels, independent of the feed slides. CNC dressing occurs through combined transverse motions of feed slide (with wheel) and cross slide (with dresser).

摘要： The present invention provides a dual flow divider for use on an extruder. The flow divider is configured to separate the melt stream received from the extruder at a central entry into two flow channels, the respective channels being formed as nearly to identical (mirror image) as is practically possible. The relative flow in the respective channels can be varied by rotating a diverter valve that extends to a position adjacent the central entry of the flow divider, i.e., where the flow begins to divide. The flow channels and control end of the diverter valve are specially configured to avoid any shape or surface conditions that would impose heat-generating restrictions to material flow, and/or allow areas of stagnation in the flow stream. More specifically, the flow channels are machined to provide smooth, streamlined transitions at all points along the flow path. The surfaces of the flow channels which intersect with the diverter valve do so at a sharp edge; this geometry blends the surfaces of the channels and valve while also serving as a "wiper" when the valve is rotated.

摘要： A pair of injection units and a common co-injection manifold are carried on a slide mounted a machine base. The machine base carries a mold element, and the injection units and manifold are moved in unison with respect to the mold element. The injection units are, in turn, carried on slideways mounted to the machine slide such that the injection units may be separately moved relative to the co-injection manifold.

摘要： A screw and nut have intermeshed helical threads which may be of a form selected from a variety of shapes; for example, a buttress thread. A ball track is formed by cooperating grooves in opposing flanks of the screw and nut threads, and a circuit of balls are disposed within the ball track. The result is a screw system with improved thrust load-carrying capability.

摘要： In a two-axis turning machine, the cutting tool unit machines a first diameter of a workpiece portion of barstock extending from a main spindle chuck. A special subspindle chuck rotating in the same direction advances axially, grasps the workpiece as it is cut off from the barstock, and retracts. The barstock is fed through the first chuck for subsequent first operation machining and located against a stop which is independent of the tool slides. The subspindle chuck rotation is reversed, displacing the first-generated workpiece axis from the subspindle axis, and a second diameter, eccentric to the first diameter, is formed by the cutting tool unit in a second operation.

摘要： Positioning errors of a moveable machine member are reduced by compensation for cyclic errors attributable to anomalies of a position transducer. Compensation values are produced which are unique only within the pitch of transducer measurement and are applied to correct the representation of measured position produced by the transducer. Positioning errors not attributable to the position transducer are corrected by compensation of position commands using compensation values associated with fixed calibration points. Use of both compensations is effective to eliminate residual errors in position correction which arise from use of calibration data created without correction of transducer cyclic errors.

摘要： A method and apparatus for limiting current through a switching device supplying current to a load. A control evaluates a model representing the switching device temperature as a nonlinear function of current and time. The model compares the temperature of the switching device to a maximum allowable temperature. The current limit is defaulted to peak current; and in response to the model detecting a temperature in excess of the maximum allowable temperature, a nominal current limit is set. The current limit reset to peak current after the model detects a switching device temperature a predetermined magnitude below the maximum allowable temperature.
