Abstract: A belt for use on a long nip press for dewatering a fibrous web includes a base fabric, woven from machine-direction and cross-machine directions yarns and taking the form of an endless loop. The base fabric many be woven from monofilaments yarns of a synthetic polymeric resin in either a single- or a multi-layer weave. At least one side of the base fabric, namely, that side which will be on the inside of the belt in its endless loop form, and which slides over the arcuate pressure shoe component of the long nip press during its operation, is coated with a polymeric resin, such as polyurethane, to render it impervious to liquids, especially lubricating oil. The coating is reinforced with a flexible layer of reinforcing fiber which may take the form of a woven sheet or may be in single filament form in single or multiple layers thereof. When in single filament form, each layer includes filaments disposed adjacent and substantially parallel to one another. The reinforcing fiber may be of a synthetic polymeric resin or of metal. In either case, the reinforcement renders the coating less susceptible to cracking and to damage from foreign objects while the belt is in use on the long nip press. <IMAGE>

Abstract: A method of controlling a welding operation during arc welding between a fusible electrode and a workpiece, wherein the welding operation alternates between arc periods and short-circuiting periods, includes the steps of sensing a first parameter of the welding operation, for example the arc voltage between the electrode and the workpiece, generating a first signal representative of the first parameter, sensing a second parameter of the welding operation, generating a second signal representative of the second parameter, filtering the second signal to provide a filtered signal, generating a desired value signal based upon the filtered signal and controlling the welding operation based upon the difference between the desired value signal and the first signal. According to the method of the present invention, any changes in the second signal that occur at a frequency outside a predetermined frequency range, which includes a desired short-circuiting frequency of the welding operation, are attenuated such that the desired value signal is less affected by these changes than by changes occurring at a frequency within the predetermined frequency range. An apparatus for carrying out the method includes a band-pass filter having a pass band including the desired short-circuiting frequency.

Granted: 1997-09-30
Abstract: A sampling system includes a plurality of sensing means (3) mounted on one or more beams (2) which reciprocate, over a moving web  (1)  of material.     The sensing zones of adjacent sensing means (3) trace out scanning paths which periodically overlap in a sampling region.    One of the sensing means  (primary)  scans over a known reference to update its calibration periodically or continuously and this is  transferred to the other  sensing means  (secondary) effectively  via  the  travelling  material  (due  to  the overlap).    Calibration is performed by signal processing means, storing and comparing monitoring signal levels or corresponding digital values derived at positions of overlap and making computations for the purpose of calibration. With sufficient overlap of the scanning paths any one of the sensors can be made redundant.     Alternatives include sensing means which move relative to other sensing means as well as rotary arrangements.
