Abstract: A method and apparatus for simulating the manner in which a ribbon of known profile is wrapped around a carcass of known profile in accordance with a predetermined winding specification is disclosed. The profile of the ribbon, the profile of the carcass and the winding specification are stored in a memory together with the desired final profile of the ribbon build. The profile of the final ribbon build, which will be created at a selected cross-section of the carcass when the ribbon is wrapped around the carcass in accordance with the winding specification, is calculated. The final ribbon build so calculated is displayed on a video display which also displays the desired final profile so that the profile created by the predetermined winding specification can be compared to the actual profile which will be produced by the winding specification.

Abstract: Apparatus for use in monitoring a plurality of variables includes a respective transducer arranged to detect a variation in a parameter and to provide an electrical output signal representative thereof and means to couple a signal associated with the output of a transducer to a display either under the control of a manually operated switching arrangement or an automatic scanning arrangement which identifies a detected variation and causes it to be displayed.

Abstract: A machining system for controlling the operation of a plurality of NC machine tools with a master controller, which is provided with an operation mode selector in a machine controller of each NC machine tool, and which is suitable for efficiently machining metal molds. The machining system allows the operator to quickly respond to a change in the condition of the production site and progress the machining operation of each NC machine tool only by manipulating the operation mode selectors without changing the machining sequence registered in advance in the master controller according to the production plan.

Abstract: Estimated fuel flow rate is calculated by reading first data of the relationship between the opening degree of a fuel control valve and a fuel flow rate. Then, a compensation coefficient is calculated based on the estimated fuel flow rate, and the actual fuel flow rate is controlled on the basis of the compensation coefficient. Estimated excess air ratio is calculated by reading second data representing the relationship between the opening rate of an air control damper and the air flow rate. Then, the actual fuel flow rate and the air flow rate are controlled depending on the predetermined relationship of values between the estimated excess air ratio and the desired excess air ratio.

Abstract: A programmable maintenance timer system suitable for use with industrial equipment such as a centrifugal water chilling system and a telemetry system including a microprocessor-based computer with a programming device for presetting selectively a maintenance time interval representing a number of hours before a maintenance service is to be performed, for counting down the time interval to zero, and for generating an output signal after the time interval has reached zero to the telemetry system so as to alert service personnel that the industrial equipment is due for a scheduled maintenance. The timer system also includes a non-volatile memory device to record permanently the total elapsed operating hours in the preset maintenance time interval so as to avoid loss of such information upon a power failure and/or back-up battery failure.

Abstract: A program-controlled knitting machine provides a method of knitting circular knit elasticized tubular goods, e.g., compressive stockings, in which the size of the goods and the amount of compression asserted when worn are controlled according to the specific size and needs of the individual using the goods.

Abstract: A method and apparatus for controlling the average thickness (T.sub.1) of a film lamina of thermoplastic, dielectric material having a known density (D.sub.1) and coextruded at a variable extrusion rate with a foam lamina of similar thermoplastic material having a thickness (T.sub.2) and the density of (D.sub.2) to form a thermoplastic laminate is disclosed. The apparatus comprises a first gauge for sensing the thickness of the laminate and for providing a caliper signal (C) corresponding to the thickness sensed and a second gauge for sensing the mass/unit-area of the laminate and for providing a mass signal (M) corresponding to the mass/unit-area sensed. The apparatus further comprises a third gauge for sensing a response to the dielectric material and its distribution in the laminate and for providing a dielectric signal (W) corresponding to the response sensed.
