Abstract: 951,433. Knitting. GEO.BRAUND Ltd. May 12,1960 [May 15,1959], No. 16662/59. Heading; D1C and D1K. Fashioning marks spaced from the selvedges of an article or garment which is fashioned by narrowing and widening each so incorporates transferred and spaced loops that one fashioning mark is a mirror image of the other; and the wales between these fashioning marks and the selvedges are substantially parallel to the wales of the fabric body part, being therefore inclined to the fashioned selvedges. The fashioning finger 1 at each selvedge has narrowing points 2, 3 at positions A, H only; and associated with these points are, for narrowing, half points 9 at positions F, G and, for widening, half points 7 and 8 at positions B, C and I, J. Thus only selvedge loops L or L4 and inner loops L1 or L7 are transferred, the wales in between remaining parallel to those of the body of the fabric; and, in narrowing, the eyelets thus formed at the inner edge of each fashioning are filled by loops L2, L3 spread inwardly by the half points 9 whilst, in widening, eyelets formed at that inner edge and also adjacent to the selvedge are filled by loops L8, L9 and L5, L6 spread outwardly. At the selvedges,the transferred loops and any spread loops are taken up in the seam.

In the measurement of the length of a metal billet 1 from a rolling mill 2, 3, pulses from a generator 7 coupled to the roll 3 are fed to a computer 8. A count is started and stopped respectively when the leading and trailing ends of the billet 1 pass a photo-cell 5 and an intermediate count is stored when the leading end of the billet passes a photo-cell 6. The final count is divided by the intermediate count and the quotient is multiplied by the distance between the photo-cells 5, 6. In a modification, a number of photo-cells 6 are provided and the intermediate count and distance of the last cell 6 which has been passed are utilized. In a further modification, instead of actual counts and distances from zero, differences are utilized. In another form, the photo-cell 5 is replaced by an electrical connection through the billet and the roll 3 or by a pressure transducer or strain gauge associated with the roll 3.
