Patent CA-1340148-C (CA)
Inventor: BUSKER LEROY H
IPC: D21H23/28
Filed: 1987-06-19
Granted: 1998-12-01
Abstract: A method is disclosed for reducing shrinkage during drying of a paper web formed from paper stock.  The method includes the steps of adding a surfactant to the paper stock prior to forming the stock into the paper web.  The surfactant is dispersed throughout the stock such that the surfactant is intimately mixed with the stock. The surfactant mixed with the stock is supplied to a headbox of a paper forming section and the mixture of stock and surfactant is ejected from the headbox onto a forming wire of the forming section.  A first portion of water is drained from the stock such that the paper web is formed on the forming wire.  The paper web is led from the forming section to an extended nip press where the web is passed through the extended nip press such that a second portion of water is removed from the web.  The pressed web is conducted through a drying section for removing a third portion of water from the formed, pressed web so that the surfactant inhibits bonding between adjacent fibers within the pressed web so that shrinkage of the pressed web during drying is reduced and a dried web of the required caliper is obtained.

Granted: 1990-12-04
Abstract: Abstract A dual status magnetic marker for use in electronic article surveillance systems, in which a piece of low coercive force, high permeability material is positioned adjacent to a piece of remanently magnetizable material.  The first piece is configured such that no characteristic response is produced when the magnetization of the entire piece is reversed by an alternating magnetic field in an interrogation zone, and when the second piece is magnetized with a predetermined pattern a localized field is provided which biases portions of the first piece, keeping those portions from reversing when the marker is in the interrogation field.  The predetermined pattern is such that the remaining, unbiased portion of the first piece has a configuration capable of producing a characteristic response when the magnetization in that portion is reversed.

Abstract: Abstract of the Disclosure Touch controlled zoom of a waveform display uses a touch screen for the display surface.  Function buttons for moving or expanding the waveform display and for determining the axis of such movement or expansion operate in conjunction with a rotary encoder.  Expansion, or zoom, is accomplished by contacting the screen overlying a point on the waveform about which zoom is desired.  Such contact or activation of the expand function button results in movement of the rotary encoder providing a gain parameter to a zoom function.  The zoom function operates on the waveform display in an exponential manner as a function of the gain parameter to expand or contract the waveform display about the zoom point according to the direction of rotation of the rotary encoder.

Title: Backflushing pressure diffuser screens
Inventor: JACOBSEN FINN
IPC: D21D5/02
Filed: 1988-08-29
Granted: 1992-10-06
Abstract: ABSTRACT      A pressure diffuser includes in a liquid-tight pressurized vessel a vertical screen and which screen and vessel wall define first and second interior volumes for transmitting pulp from a pulp inlet to a pulp outlet and receiving displacement (e.g. wash or bleach) liquid transmitted from headers through the pulp.  The screen ends have different cross-sectional areas, and quick movement of the screen effects backflushing.  The volumes are segregated by a vertical, generally cylindrical, screen.  A chamber is provided in communication on opposite sides of a piston therein with the pulp adjacent the pulp inlet and the extracted liquid.  By displacing the piston immediately prior to rapidly moving the screen vertically to effect backflushing through the screen, the pulp pressure on the screen is being reduced and at the same time a volume is made available adjacent the pulp inlet in the chamber thus avoiding pressure shocks and compaction of the pulp adjacent the inlet caused by the movement of the screen.

Abstract: DECORATION OF SHEETING                      ABSTRACT    A method for decoration of paper or plastic sheeting and other substrates, involving a novel technique for coating and embossing the substrate.  The paper or plastic sheeting is supplied with a coating of thermosensitive material, as by extrusion.  The coated sheet is heated to adequately soften the coating, such as by use of a heated cylinder, and remote heat sources such as infrared heaters. The softened sheet surface is then decorated using an embossing member, to provide a diffraction pattern or hologram.  Use of an embossment pattern of lesser depth than the surface roughness of the sheet before embossing provides attractive decorative patterns.

Abstract: A  method  and  system  (10)  for  controlling  radial movement of a machine tool,  such as a turning machine, relative  to  a  workpiece  (11), is  characterized  by  a digital  filter  (70,  72,  74)  which produces a  filtered final control signal which is a function of both radial position  and  velocity  of  a  cutting  tool  (24)  of  the turning machine.   The method and system (10) utilizes a tool position feedback signal which is compared with an initial control signal to produce a signal which is then digitally  filtered to,  in  turn,  provide the  resulting final  control  signal.    The  surface  geometry  of  the workpiece (11), such as a piston, is determined by a data matrix of angular, axial and radial position coordinants of the tool.  An angular position signal representative of the angular position of the workpiece (11) and an axial position signal representative of the axial position of the cutting tool (24) relative to the workpiece (11) are both generated.   The angular and axial position signals are  correlated  with  the  data  matrix  to  generate  the initial control signal.   The control loop of the system (10)  is closed within the software portion of the system (10)  for increased reliability.   Also, there is no need for velocity loop feedback with a velocity transducer. Feed  forward compensation is performed in the software portion of the system (10).  The digital filter (70, 72, 74)  is preferably implemented with a digital algorithm on a  digital  signal  processing  microprocessor of an  axis control board (38).   The digital filter (70, 72, 74)  is either an infinite-impulse-response type (i.e. recursive) or  a  finite-impulse-response  type  (non-recursive)  from which control, such as PID control, can be derived.
