Title: Process for removing metal ions from liquids
Inventor: MICHALOWSKI ROBERT J
IPC: D21C9/00
Filed: 1994-06-30
Abstract: The invention is an improvement in a process for making cellulosic articles said process involving a separation of cellulosic material from a mixture containing a liquid, metal cations, and cellulosic material. The improvement involves adding to the mixture at least one retaining material which binds at least one metal cation and, in the separation, is retained with the cellulosic material. Suitable retaining agents are either organic or inorganic and include chelate-forming polymers, both synthetic and natural, colloidal suspensions of inorganic compounds, and mixed metal hydroxides. In each case, the metal cations remain in the cellulosic article, for example paper, rather going into waste water from which they would otherwise need to the removed.

Title: Self-tightening side lock for a roll-up door
Inventor: CLAY ROY T JR
IPC: E05B65/00
Filed: 1996-01-11
Abstract: A self-tightening side lock (20) for a roll-up door includes a keeper (25) mounted on the jamb, and a latch member (26) pivotally mounted on a door panel. The latch member is selectively cooperable with a catch (30) to hold the door in a closed position. The latch member is biased to move in a counter-clockwise direction. The latch member is adapted to be moved in a clockwise direction, against the opposing bias or a spring 42, to an out-of-the-way position at which the displaced latch may pass by the catch. The latch member has a side cam surface (33) arranged to engage the catch (30) when the door is lowered and to cause the latch member to pivot in a clockwise direc-tion toward the out-of-the-way position to allow the latch member to pass by the catch. The latch member also has an upper cam surface (34) arranged to engage the catch such that the counter-clockwise movement of the latch member will cause the door to be self-tightening. A notch (50) extends radially into the latch member from the upper cam surface adjacent the side cam surface. The notch member is so configured and arranged as to receive the catch and to prevent further pivotal movement of the latch member. The improved side lock will thwart the efforts of would-be thief who might attempt to force the door upwardly with the upper cam surface engaging the catch.

Abstract: A method and apparatus for lateral alignment of a cross-direction profile control of a web as required in a paper-making process.   In the method, a certain cross-direction profile of a dried web, particularly the basis weight profile thereof, to be aligned is gauged.  A profile measurement signal thus obtained is passed to a control system of the paper machine which provides a control signal suited to control adjustment devices of the cross-direction profile control provision.  The web is provided with at least one marker line whose lateral shift or shifts is/are detected at the measurement point of the cross-direction profile of the dried web,  or in the vicinity thereof.   The detection of the lateral shift(s) is used to generate a measurement signal thereof which is employed to control the lateral alignment of the web profile adjustment provision.  The information obtained from the detected lateral shift(s) then used in the control of the lateral alignment of the consistency profile control provision adapted in conjunction with the paper machine headbox.  The marker agent used to make the marker line is injected to the stock at the inlet side of the stock feed channel to the paper machine headbox,  most advantageously close to the control valve set of the consistency profile control provision.

Title: Driver error compensation in a flat panel display
Inventor: JOHNSON MICHAEL J
IPC: G09G3/36
Filed: 1995-07-14
Abstract: A method and apparatus for providing error voltage compensation in a flat panel display. Voltage errors in a column driver for a flat panel display are compensated for by first measuring the voltage level at each column during a known signal level period and comparing it against a known or reference value. This voltage error signal is then stored in an error memory according to column location. During normal operation of the flat panel display, the memory is accessed every time a particular column is scanned. The error voltage is retrieved and added to the raw video signal in order to remove any voltage offset which is introduced in the column driver electronics. This error voltage compensation substance eliminates any streaking which may appear on a display screen.
