Patent CA-2102882-A1 (CA)
Inventor: DORICA JOSEPH
IPC: C02F1/52
Filed: 1993-11-10
Abstract: A process is presented for removal of suspended solids including resin and fatty acids from pulp mill effluents including Chemi-Thermo-Mechanical Pulp (CTMP) mill and deinking effluents. The process involves filtration of untreated or primary treated effluents through a mat of primary sludge, pulp or woodroom sludge. A sludge mat is formed on a belt or drum filter wire screen or punched drum and the effluent to be treated is filtered through the mat.      Most of the suspended solids and a part of colloidal material and dissolved solids are retained by the mat.      Following the filtration stage, the sludge is dewatered and removed. A portion of the sludge is recycled to form the mat for the next filtration cycle, while the excess sludge is purged. The filtration is achieved by the application of vacuum below the filter mat ar pressure over the mat. The process will produce treated effluent with low suspended solids and sludge at high solids consistency and can eliminate the need not only for a clarifier but also for sludge thickening and filtration units often used in pulp mills. Calcium chloride may be added to the effluent prior to primary settling or before filtration, to enhance the removal of suspended and total solids.

Abstract: Hollow  synthetic  monofilament  yarns  are  used  in  the construction of a base fabric for a papermakers wet felt.   The synthetic hollow monofilament yarns have selected interior void, compressibility and resiliency characteristics and are interwoven with other yarns to form a woven base fabric with the hollow monofilament yarns predominating, on at least the paper carrying side of the base fabric.  The weaving and finishing of the base fabric  results  in  the  hollow monofilament  yarns  retaining  a substantially    unflattened    cross-section.        Accordingly, substantially unflattened portions of the hollow monofilament yarns predominate the paper carrying side of the base fabric thereby providing a cushioning surface which is compressibly resilient to assist in the dewatering of the  aqueous paper web as  it  is transported through a press nip during the manufacture of the paper.  Hollow nylon monofilament yarns having approximately 18% internal  core  void  have  been  found  to  exhibit  the  desired compressibility  and resiliency characteristics.    Preferably a fibrous batt is needled to the base fabric to finish the wet press felt.

Filed: 1993-10-18
Abstract: In a demountable office partition system, batten mounts with a base and legs of a resilient hard plastic are snap fit to supporting structures by reason of inwardly directed opposed flanges on the legs.  The legs of the batten mounts also have soft plastic externally directed fingers to which a batten may be press fit.  Use of the batten mounts permits the batten to be removed without damage.  In another embodiment, the base of the batten mounts have a first set of depending inner legs with inwardly directed flanges and a second pair of depending outer legs with outwardly directed flanges outwardly spaced from the inner legs.  The batten mount is fabricated of a resilient hard plastic.   Again,  the  batten mounts  may  be  snap  fit  to  a supporting structure.  However, in this embodiment, a batten is snap fit to the batten mounts.  The batten may be removed from the batten mount without damage due to the resilience of the outer legs.

Title: Armoire
Inventor: DHAEMERS GREGORY
IPC: D06F34/26
Filed: 1993-10-26
Abstract: A dryer has an internal drying chamber for accommodating articles that are subjected to a heated circulating air to remove moisture from the articles. An air mixing chamber contains a first fan for moving air through a heater into the drying chamber. A second fan draws air out of the drying and mixing chambers and discharges air through a filter into the external environment. The heated air in the drying chamber is mixed with fresh air and recirculated through the drying chamber to minimize heat losses and increase drying effectiveness. Ultraviolet lamps within the drying chamber destroy contaminants in the air and articles within the chamber. A boot dryer, located in the drying chamber, has fans that move air through tubes used to support boots, shoes, skates and socks.   Ultraviolet light in the boot chamber destroy contaminants in the air in the boot chamber and articles supported on the tubes. One modification of the dryer located within a locker room is used to remove moisture and odors from the air in the locker room.    The dryer has a dehumidifier for cooling and removing moisture from the air, a heater coil for heating the air, ultraviolet lights for destroying contaminants and a charcoal filter for removing odors from the air flowing out of the dryer. Another modification of the dryer has a portable housing supporting a heater and a fan for moving air through filters and a drying chamber.

Title: Paper surface roughness analyzer
Inventor: ROGOWSKI DONALD F
IPC: G01N33/34
Filed: 1994-01-04
Abstract: PAPER SURFACE ROUGHNESS ANALYZER     ABSTRACT OF THE DISCLOSURE         Subjective paper characteristics such as visual appear-ance and print quality are often objectively related to certain scales of surface roughness.  Three dimensional topographic surface data is obtained from a paper sample secured by vacuum to a flat, porous plate for translational movement in a grid pattern beneath a vertically compliant stylus that is resiliently suspended beneath a rigid, overhead support beam.  Such surface data is mathematical-ly filtered by a linear convolution technique or the distinctly alternative circular convolution technique to segregate the raw data  characteristics  of  component  surfaces  that  contain  only certain frequencies of roughness.  The root-mean-square variations of such component surfaces is then used to objectively characterize respective surface characteristics.
