Abstract: COLOR SORTING OF LUMBER             ABSTRACT OF THE DISCLOSURE         A system for sorting lumber using a scanning camera that generates separate red, green and in some cases blue outputs to scan selected length increments along the surface of a piece of  lumber  and  such  data  collected  for  each  color  is  each separately histogrammed to produce a frequency distribution of color intensity.   The data is analyzed to determine the mean values for each color in the selected lengths and the lengths characterized based on these mean values into specific colors.          The  lumber  pieces  may be  automatically  severed  into  pieces having  significant  differences  in  color  and the  pieces  of significantly different colors may be automatically collected in different  groupings.    In  an  alternative  arrangement  the histogram  for selected  color  is  analyzed  to  determine  the frequency distribution and degree of frequency variability to determine if it is to be classified as vertical or flat grained.          The  lumber  pieces  may be  automatically  severed  into pieces whenever their classification changes between flat and vertical grain and the pieces of flat grain may be automatically collected separate from those of vertical grain.

Abstract: ABSTRACT     A connector for discharge electrodes of luminous gas tubes includes an insulative barrel receiving a power cable at one end for attachment to a fixed end of a resilient contact member. The opposite end of the barrel is open and threaded, to receive the crimped and headed tip of a gas tube having electrode conductors projecting therefrom.   A lock element applied to the crimped portion of the gas tube end and is axially captured thereon so that following insertion of the tube tip and lock element into the barrel open end, a cap surrounding the gas tube engages the threads of the barrel to radially and axially retain the tube tip within the barrel interior with its electrode conductors firmly biased against a displaceable end of the resilient contact member.  In an alternate embodiment, the same lock element serves to secure each of a pair of gas tube tips within a housing having a contact member provided with displaceable end segments serving to electrically join the electrode conductors of the pairs of gas tubes.
