Abstract: Two rolls (34, 36) are mounted to a frame (30) and rotated about spaced parallel axes (62) by electric motors (56) operating through speed reducers (58). Each roll (34, 36) has a surface (40, 42) formed of uniformly spaced, circumferential extending triangular grooves (44) and ridges (46) defined between grooves (44). The ridges (46) of one roll (34, 36) are closely spaced from the grooves (44) of the other roll (34, 36) to define a sinuous nip (32) therebetween. A vibrating conveyor (23) orients wood strands (22) and feeds the strands (22) to the nip (32) with the grain of the strands (22) parallel to the roll ridges (46) and grooves (44). Wood strands (22) have low strength transverse to the direction of the grain and, thus, when forced to flex by the interdigitating ridges (46) and grooves (44) of the opposed rolls (34, 36), split into narrower strands.

Title: Method for controlling the level of detail displayed in a computer generated screen display of a complex structure
Inventor: BRECHNER ERIC L
IPC: G06T15/00
Filed: 1995-10-26
Granted: 2008-04-01
Abstract: A method is described for controlling the level of detail displayed in a computer generated screen display of a complex structure wherein the structure is modeled as a root volume bounding all of the parts of the structure, with the indi-vidual parts comprising sub-objects bounded in sub-volumes. The method begins by selecting the root volume (202) and then enters the step of determining whether or not all sub-objects within the selected volume are turned off (204). If they are, the entire display is culled. If they are not, the system then computes the screen coordinates of the selected volume (208). The method pro-ceeds to the step of determining whether or not the selected volume is on the screen or off. If it is off the screen, the entire volume is culled.  If it is on screen, however, a determination is made as to whether or not all sub-objects are turned on (214). If all sub-objects are turned on, the number of screen pixels for the selected volume is computed (216). This screen size is compared to a user defined threshold (218) and if it is smaller than the threshold, the object is drawn as a bounding volume (220). If the selected object is larger than the threshold, a determination is made (230) as to whether or not the object includes sub-volumes. If it does not, the detailed object is drawn (232). If it does include sub-volumes, the system passes each sub-volume (240) back to the step of determining whether or not all sub-objects are turned off (204) to thereby determine for the entire root volume and all sub-volumes the appropriate level of detail to be displayed. The color for any given volume within a level of detail is determined by algebraic summation of the color of all sub-volumes within a parent volume weighted by the ratio of the sub-volume's volume to the parent's volume raised to the 2/3 power. This provides a crude inverse square fall off of intensity of the sub-volumes color to the parent's volume with pleasing results.

Title: Cemented carbide body with improved high temperature and thermomechanical properties
Inventor: ERICSON THOMAS
IPC: B24D3/06

Granted: 2006-05-16
Abstract: According to the invention there is now provided a cemented carbide grade for rock excavation purposes with 96-88 % WC, preferably 95-91 wt-% WC with a binder phase consisting of only Co or Co and Ni, with maximum 25% of the binder being Ni, possibly with small additions of rare earth metals, for example Ce and Y, up to max 2% of the total cemented carbide. The WC grains are rounded because of the process of coating the WC with Co, and not recrystallized or showing grain growth or very sharp cornered grains like conventionally milled WC, thus giving the bodies according to the invention surprisingly high thermal conductivity.      The average grain size should be 8-30 µm, preferably 12-20 µm. The maximum grain size does not exceed two times the average value and no more than 2 % of the grains found in the structure are less than half of the average grain size.

Abstract: A smoke exhausting device is disclosed. It includes a housing partitioned into two internal rooms. One of the rooms is a bellows for creating pressure, while the other is a guide box for guiding the smoke. The bellows has an entrance  communicated with the  guide  box  and  an  exit communicated with outer side of the housing.  The guide box surrounds a front side, right side,  left side and a bottom face of the bellows and is spaced from the bellows to  define a  path  for  air  flow  to  smoothly  pass therethrough. Each of the three sides is disposed with at least one sucking mouth, which is communicated with the entrance.  A  bottom  of  the  housing  is  formed  with  a downward  inclined  oil  guiding  section  having  an  oil outlet  at  bottom  end.  The  housing  can  be  easily disassembled from the funnel and the sucking mouths of the guide box can be disposed at different positions in different directions, so that the smoke exhausting device is applicable to different sites.

Abstract: A crimper assembly includes upper and lower crimper bars which are rotated relative to a sheet of packaging material. A pair of upper crimpers are secured to opposite sides of the upper crimper bar, while a pair of lower crimpers are secured to opposite sides of the lower crimper bars. Each of the upper crimpers includes a metallic base having an outwardly facing portion with an undulating cross sectional shape. A slot is formed in the outwardly facing portion of the upper crimper, and a cutting blade is retained therein. In a first embodiment, an insert is secured to the base of each of the upper crimpers.  The insert includes a rigid shank having a lip portion extending therefrom.  Portions of the outer surface of the shank are covered by a layer of a relatively resilient material. The layer is formed from a material which is suitable for compressing overlapping portions of the folded sheet of packaging material to form an intermeshing seal pattern. The outwardly facing portion of the layer of resilient material includes a longitudinally extending, outwardly facing resilient crimping surface with an undulating cross sectional shape. The lower crimpers are formed in a similar manner, except that an anvil is retained within the slot. During operation, the crimpers are rotated such that the folded sheet of packaging material is compressed between the downwardly facing undulating surface of the upper resilient layer and the upwardly facing undulating surface of the lower base. As a result, the overlapping layers which make up the folded sheet of packaging material are sealed together to form a trailing edge seal for a packaged article. The cutting blade and anvil cooperate to cut the sealed packaging material into individual units.
