    摘要: Circuit (10) for generating an error voltage (26) which is proportional to the difference between a desired value of a physical parameter and the actual value of the physical parameter. The circuit (10) operates by alternately switching the current from a source (13) through a fixed resistor (11) and a variable resistor (12), the resistance value of which changes as a function of the physical parameter to be controlled. The current is switched between the two resistors so that the average voltage generated across the variable resistor would be equal to the average voltage generated across the fixed resistor if the physical parameter had the desired value. By determining the difference between the average voltage across the resistors, the error voltage (26) can be generated for controlling the physical parameter.

    摘要: The system controls formation of wet stock (55) comprising fibers on a moving water permeable wire (13) of a de-watering machine that has a refiner (135) that is subject to a variable load and a headbox (10) having at least one slice (50), wherein each slice (50) has an aperture through which wet stock (55) is discharged at a stock jet speed onto the wire (13) that is moving at a wire (13) speed. A sheet of wet stock (55) moving a speed develops on the wire (13). The system includes: a) at least two water weight sensors (42A-42E) that are positioned adjacent to the wire wherein the at least two sensors (42A-42E) are positioned at different locations in the direction of movement of the wire (13) and upstream from a dry line (43) which develops during operation of the machine and the sensors (42A-42E) generate signals indicative of a water weight profile made up of a multiplicity of water weight measurements; and b) adjustability of at least one of the stock jet speed, sheet speed, wire speed, or refiner load to cause the water weight profile to match a preselected or optimal water weight profile.

    摘要: Driving power for a vibrating device (10) is provided at less than full level when the device is initially used. Power is gradually increased in successive steps after a selected number of uses in each step until full power is achieved. Also, a battery-energized driving signal for a vibrating device has a selected characteristic, such as duty cycle, which is set initially at less than an optimum value, when the battery which is contained within the driver assembly (22) is at full strengh. As the battery discharges, the selected characteristic is adjusted toward optimum so as to compensate for reduction in the battery voltage and ensure full power output.

    摘要: An apparatus automatically generates a tape (1) having splice area and other markings which indicate acceptable splice points on a length of fabric from which garment pattern pieces are to be cut. The apparatus includes a computer (100) for calculating splice and other pertinent points on a fabric layup. The apparatus also includes a controller (14) for receiving printing commands from the computer (100). The apparatus also includes a printer (12) responsive to signals from the controller (14) for quickly and accurately printing on the tape (1) splice information and data identifiying the marker for which the splice point indicating tape (1) was generated. The apparatus also includes a tape advance system (10) for advancing the tape (1) form a supply roll (16) to the printer (12) and then to a takeup roll (28).
