Abstract: ABSTRACT OF THE DISCLOSURE       System For Controlling A Puller Assembly In a system for controlling a puller assembly (3) for withdrawing an extruded section as it exits from an extruder, in which the puller assembly (3) is moved in withdrawing direction by means of a drive mechanism (9), the actual speed with which the extruded section (1) is withdrawn is sensed by means of a tachometer (34) and is delivered to a speed controller (32) for controlling the speed of the drive mechanism (9) for the puller assembly. Optimum pulling force  may be adjusted by providing follower means (11, 12) between the puller assembly (3) and the drive mechanism (9), said follower means being acted on by an actuator (15) for permitting relative movement between a drive member (8) and the puller assembly. The relative movement of a follower (11) is delivered via a displacement detector (30) to the speed controller (32) as a disturbance factor. (Fig. 1)

Abstract: ABSTRACT OF THE DISCLOSURE         The improved joint connection provides a separate stress ring for each of the compressive loading zone and tensile loading zone at the and of a timber beam and a central stem secured to one ring and unsecured to the other ring.          The connection is such that shrinkage in the timber beam along the major axis of the cross section can be accommodated by movement of the unsecured stress ring relative to the stem.  A plate is provided at the end of the stem to retain the moveable stress ring in the joint connection.  In one embodiment, a pair of one-piece connectors can be secured at the end of each timber between the timber  and the respective stress rings of the joint connection.  In another embodiment, a second pair of coaxial and concentric rings may be employed with the outer rings  being of polygonal shape to have flat sides against which the respective beams may be secured.  In still another embodiment, the stress rings and stem may have a polygonal shape.

Abstract: CONTOUR LINE SCANNER               ABSTRACT OF THE DISCLOSURE An edging system for sawing cants into boards includes a contour line scanner for profiling the cant and determining  the combination of board widths of a specified grade which will yield the greatest economic return based on current prices.  The scanner includes a pair of fan-like lasers positioned along a conveyor for projecting coplanar lines of light onto the side faces of the cant to  form contour  lines characterizing  the widthwise position and shape of the side faces.  An X-V axis TV camera is positioned above the cant for raster scanning the cant widthwise (X-axis) at close lengthwise (Y-axis)  intervals along the cant to detect the contour line.  The camera output signal is input to a digitizer, which  includes  a  timer  to convert  the  signal  to  two digital members corresponding  to the positions of the contour lines at each interval.  A microcomputer is pro-grammed to fit two parallel sawlines between the contour lines,  one sawline touching one  contour  line  and  the second  sawline  touching  or  near  the  second  contour line.   Board  values,  tabulated  by  grade,  width and length of the boards, is stored in the computer memory. The positions of the second and additional sawlines are determined  by  computing  all  combinations  of  standard width boards that can be cut between the contour lines; totaling from the price data the value of lumber in each combination;  selecting  the  combination  providing  the greatest  value;  and  positioning  the  second  and addi-tional sawlines to saw that combination.  The elevation of the laser lines and the board values used in comput-ing total lumber values are jointly varied for different grades of lumber.

Abstract: ABSTRACT     A method and an apparatus are described which are useful for respiratory tract therapy.  The method comprises contact of mucous membranes with vapor-phase water in the substantial absence of nucleating water-vapor condensation particulate, and includes the use of a heated delivery tube, unheated nasal cannula, for the delivery of a nasal cannula vapor/gas stream to a nasal passageway at delivery rates in excess of 8 liters per minute at dew point temperatures equal to or less than dry bulb temperatures and heating of a delivery tube vapor-gas stream to a temperature sufficiently greater than the cannula nare dew point use temperature in order to cause a readily observable cannula condensation film to form near the exit use ports thereby signaling that the appropriate cannula delivery stream dew point-dry bulb temperature differential exists which insures that the dry bulb nare exit temperature is equal to or greater than the nare dew point use temperature.

Abstract: AIR FILTER AND METHOD OF MATERIAL SUPPORT               ABSTRACT OF THE DISCLOSURE      A first layer of an air-transmitting media or support is applied onto a heated forming die contoured to define a plurality of pockets. A mating heated die is pressed against that forming die with the media disposed thereinbetween, and the pressure is maintained until corresponding pockets are formed in the media.          After the media has cooled, the pockets in the media are filled with particles of air treatment material.  A second layer of air-transmitting media is then applied upon the forming die in covering relationship to the particles, after which a heated sealing die, contoured to mate with the forming die and aligned to allow mating of respective mutually-facing surfaces through said layers, is pressed toward the forming die.  The pressure is maintained for a time sufficient to obtain a non-permeable seal around each of the pockets.

Abstract: ABSTRACT OF THE DISCLOSURE           An imaging system for providing apparatus and method for projecting a two dimensional (2D) representation of three dimensional (3D) volumes where surface boundaries and objects internal to the volumes are readily shown, and hidden surfaces and the surface boundaries themselves are accurately rendered.  In the present invention, the two dimensional image produced is capable of having the same resolution as the sampling resolution of the input image volume of interest.  This is accomplished through the implementation of methods for determining "partial volumes" of voxels.  Partial voluming provides for the assignment of selected colors and opacities to different materials (or data components) represented in an image data volume based on the percentage composition of materials represented in each voxel of the image volume.  Unlike prior are systems, such as those that use thresholding techniques, the imaging of the present invention has a high degree of precision and definition that is independent of image volume on a per voxel basis.
