Abstract: A slice lip apparatus is disclosed for guiding a flow of stock from a headbox so that the stock flows between a first and a second wire of a former. The apparatus includes a lip which is disposed adjacent to the first wire. A movable lip is spaced relative to the lip so that the lips defined therebetween a slice for the passage therethrough of the flow of stock. An adjustable guide shoe is disposed adjacent to the movable lip for guiding the second wire. A linkage extends between the movable lip and the adjustable guide shoe. The arrangement is such that when the movable lip is selectively moved relative to the lip, such selective movement generates a corresponding movement of the adjustable guide shoe relative to the first wire.

Abstract: In a papermaking machine for forming tissue paper, a turning bar is disposed having a curved surface about which a web of tissue paper is turned. The bar has an internal air plenum which supplies air to two sets of holes or slots. The first set is arranged to direct air normal to the curved surface of the bar or in the machine direction, the second set is arranged to direct air toward the edges of the tissue which is turned around the bar. The second holes or slots produce air jets which apply a cross machine direction tension to the web which prevents wrinkling of the web. The first set of holes or slots forms jets of air that prevent the tissue web from contacting the turning bar.

Abstract: A web support foil positioned adjacent to a Yankee dryer above a creping doctor. The foil supports the web as it leaves the dryer. Mounted to the top of the foil is an adjustable air deflector which is positioned tangent to the Yankee dryer. The air deflector blocks air moving along the web. A slotted opening draws air from a leading-edge pocket collecting fibers which are broken loose during the creping action. The web is held against the bottom side of the foil by one or more air jets which are directed over the bottom surface on the foil. The jets of air function as coanda air jets and prevent the web from sticking to the bottom surface of the foil while creating a Bernoulli effect which holds the web against the bottom of the foil.

Abstract: An apparatus includes a forming section for forming a web from stock. The apparatus also includes a press section which is disposed downstream relative to the forming section for removing a portion of water from the formed web. The press section includes a suction pick-up roll disposed downstream relative to the forming section for picking up the formed web from the forming section. A press felt extends around the suction pick-up roll such that in use of the apparatus, the formed web is picked up from the forming section and is supported by the press felt. An extended nip press is disposed downstream relative to the pick-up means. The press includes a rotatable backing roll and a pressing shoe which cooperates with the backing roll for defining therebetween an elongate pressing section. A bearing blanket movably extends through the pressing section with the blanket cooperating with the suction pick-up roll such that the formed web is transferred from the press felt to the blanket.

Abstract: Linear and switching amplifiers associated with acoustic transducers requ a gradual turn-on rather than an abrupt full-power level signal. A transducer preamplifier power controller circuit prevents the operation of fuses and the tripping of circuit breakers when the relatively high power driving levels for a sonar transducer are initiated. The controller circuit gradually increases a signal level from a zero level to a maximum during the initiation of a sonar signal using a threshold level that is set to a fraction of the expected maximum, and two discrete clock frequencies, for example at 1 MHz and 2 KHz actuate interconnected digital control elements incrementally to increase the signal level during a predetermined period. This cycle is re-initiated by the next sonar signal.

Abstract: Apparatus for transferring a newly formed paper web from the forming fabric over a couch roll in a papermaking machine includes a transfer roll which guides a pick-up felt into nipping engagement with the paper web over the couch roll. The nip is located intermediate the circumferentially spaced ends of a vacuum zone on the surface of the couch roll. The web with the forming fabric on one side and the pick-up felt on the other side is guided onto the transfer roll surface by the forming fabric downstream of the nip and is transferred onto the pick-up felt. The transfer roll has a vacuum zone located downstream of where it is wrapped by the forming fabric. The application of pressure on the web over the couch roll prior to, and in conjunction with, the nip operates to further dewater the web as well as to facilitate its transfer to the pick-up felt.

Abstract: An apparatus for extracting, storing and repetitively replaying a broadband atasample is fabricated from proven electronic components to assure long term reliability and reproducibility. A broadband acoustic signal is digitized and stored in a RAM until it is loaded with the desired signal. An adjustable clock controls the rate at which the stored signal is loaded and repetitively displayed so that its spectrum and characteristics can be fully analyzed. Appropriate filters are provided on the input and output sides to block incoming signals outside of the range of interest and those signal components attributed to the variable clock. Selection of particular portions of the stored desired signal may be addressed for detailed analysis on a repetitive basis if needed.

Abstract: An electronic system that processes or otherwise acts upon a serial data stream can be monitored at any one of several points to provide an indication that specific parts as well as the whole system are functioning properly. A selected digital address is dialed on a thumbwheel switch that provides a signal indicative of a particular time slot within a repetitive sequence of time slots and a counter produces a series of digital addresses that are representative of a repetitive sequence of time slots to enable a comparison and generation of a latch signal at the particular time slot indicated. A probe is placed in electrical engagement with that portion of the signal corresponding to the selected digital address and a series test input signal is drawn from the system.

Abstract: A programmable bootstrap loader device for loading or transferring programs nto the main memory of a computer system includes a processor-peripheral interface for decoding instructions of the computer system and for generating control signals to operate peripheral equipment coupled to the system. An alterable or programmable memory stores a set of instructions which makes up a bootstrap loader program, is not lost when power to the system is shut off. An alterable memory access circuit is coupled between the processor-peripheral interface and the alterable memory to enable an operator to alter discrete instructions of the stored bootstrap loader program.

Abstract: A core clamp mechanism serves to grip a core on a winder shaft by means of a plurality of ring elements and an expandable elastomer tube. A spacer sleeve abuts at one end with the free end of the core and receives, at its other end, a locking disc in preformed engagement spaces which cooperate with lugs formed on the disc. The elastomer tube is positioned upstream of the disc and supplied with air pressure for expansion of the tube against the disc which serves to compress the sleeve against the core. Shrinkage and other adjustments during the clamping operation are automatically accommodated by axial expansion of the tube under pressure. To remove a wound core, pressure is released through a valve from the tube and the disc moved clear from engagement with the sleeve. Cutouts corresponding to the disc lugs are formed on the sleeve so that, by aligning the cutouts with the disc lugs, the sleeve can be pulled off the shaft and the core removed and replaced.

Abstract: Web flutter is suppressed by means of one or more foils along the path of movement of the web which may be porous, such as tissue, whether creped or not, or may be substantially non-porous. For porous web, the foil may be imperforate. For non-porous web, the foil may be foraminous. As the web travels at high speed in adjacently spaced relation to the foil, surface air pressure tends to be greater on the surface of the web opposite the web surface which faces the foil, thus tending to thrust the travelling web toward the foil, and thus stabilizing web travel and suppressing tendency for the web to flutter as it travels freely between supports such as a dryer and a calender.

The calender may comprise a single roll or a plurality of rolls. A split torque arrangement is provided for the reel drum and the reel core. Especially useful for handling creped tissue paper web.

Abstract: Loss of a magnetic track on a rotating drum memory is compensated for by a erially connected shift register. Since replacement of an entire magnetic drum is a costly venture, it usually is not warranted when only one or two or several tracks have become corroded or otherwise scored. The shift register is provided with an appropriate amount of stages to handle the data otherwise stored on a damaged magnetic drum track. Provision is made in the inventive concept herein disclosed for providing index and clock signals in event of the failure of the index and clocking tracks in the memory drum.
