Title: Use of dadmac containing polymers for coated broke treatment
Inventor: ST JOHN MICHAEL R
IPC: D21H17/45
Filed: 1990-06-11
Abstract: DADMAC containing polymers, both homopolymers and copolymers are used in effective coagulating amounts to treat cellulosic fibres recycled from coated broke recovery. The DADMAC containing polymers are either homopolymers or are preferably copolymers containing acrylamide. Recycle of coated broke can cause difficulties when the fibres are recycled to the paper manufacturing process because the coatings contain binders which cause what is referred to as "white pitch", the accumulation of which can cause holes in the paper, build-up of residues and sticky masses, and clogging of felts and the like in the manufacture of paper. The use of the DADMAC polymers eliminates this difficulty in making paper from recycled cellulose fibres obtained from coated broke recycle.

Filed: 1990-10-15
Abstract: Abstract Wheeled  containers  for  tube  transport,   comprising  the following elements of structure and operation: a)  tube wheeled bogies with  polymer wheels laterally  disposed and between them at the bottom double flanged steel rollers; b)   on  this bogies  there are  vertical masts  with stabilizing rollers at the top; c)   the  container has  gondola with  rotation shafts  above the center of  gravity of gondola  supported via spherical  joints on the said tube wheeled bogies; d)   on  the gondolas  there  are rigid  arms with  rollers,  the symmetry  axis of the rotation shaft, vertical masts and the said rigid arms form  a vertical  plane passing  through the  symmetry plane of the gondola in cruise position; e)   also  the containers  have chain  driving  means in  form of articulated  dogs  articulated  to  the  gondola,  kept retracted (without  touching the  tube)  by  a  magnet  retainer  or  by  a mechanical  hook latching  mechanism which  could be  released by external stationary rollers permitting the containers to be chain driven. The way of operation is as follows: a)   the tube  wheeled bogie  is entering  via the  bottom double flanged  rollers  on a  rail and  the roller  at  the top  of the Wheeled Containers for Tube Transport vertical  mast  in  another  rail,  then  the  bogie is inclined laterally,  but  the gondola  and the  arm  with roller  tends to remain  vertical and  could enter  into another  rail which  is a helical cam determining  the rotation of  the gondola around  the axis and implicitly unloading the material contained in it. b)   as far as concerning  the chains driving system  it works as follows:   when  a stationary roller  is releasing the chain drive dog and this  able to  chain drive  the containers,  then when  the chain driving is finished another stationary  roller is pushing back the chain  driving  dog and  this is  caught  either by  the magnetic retainer or by mechanical latching mechanism.

Title: Scaffold couplers
Inventor: LEGGE PHILIP
IPC: E04G7/14
Filed: 1991-01-03
Abstract: A scaffold coupler is actuated by an over-centre lever mechanism. The scaffold coupler, which is of resilient plastics, includes a hand lever 13. which is hinged to a jaw 12 that closes upon a base member 11 to clamp tight a scaffolding tube 15. A hook member 14 hinged to the lever 13 engages with a lip 19 of the member 11 so that depression of the lever 13 urges the jaw 12 hard onto the tube 15 and actuates the clamping mechanism by pulling the hook-hinge 22 through 'over-centre' alignment with the lever-jaw hinge 21 and the hook-lip engagement 'hinge' 23. The base-jaw surface 17 subtends more than 180 degrees to snap fit with the tube 15, and opening of the closure jaw 12 is limited by a projection 20 (or otherwise, Figure 7) for support of the tube 15 (Figure 2). Closing of the jaw 12 may be tripped by entry of the tube 15 (Figure 6), and the jaws may be abrasive-surfaced (Figure 5) to improve grip. The lever 13 may be selectively locked in the actuated. condition (Figures 19 to 24), and other configurations of over-centre lever mechanism are possible (Figures 25 to 29). Right-angle, swivel and sleeve couplers (Figures 9, 10-13, 17-18) include two over-centre mechanisms, whereas a putlog coupler (Figures 14-15, 16) includes one, with the second pair of jaws actuated by one or more levers 63 that bear on the tube 62 clamped by the first pair.

Title: Reflective Grain Defect Scanning
Inventor: MATTHEWS PETER C
IPC: G01N21/55
Filed: 1992-03-06
Abstract: Grain defect scanning is accomplished by a pair of light detectors directed toward an inspection point illuminated by a collimated light beam incident upon the inspection surface at a given angle of incidence.  one detector, the specular detector, is positioned along the specular angle of reflection as defined by the angle of incidence and the other detector, the diffuse detector, lies substantially along the angle of incidence.   When specular reflection dominates, as when the inspection point corresponds to clearwood,  the specular detector indicates a higher reflective light intensity than the diffuse detector.  When diffuse reflection dominates, however, as when the inspection point corresponds to a grain defect, both detectors indicate similar reflective light intensity.    Grain  defect  discrimination  is  accomplished  by calculating a ratio of specular detector output to diffuse detector output.   Further  analysis  of  the relative magnitudes  of the detector outputs provides a basis for identifying grading marks, such as ink and wax marks, at the inspection point.
