Filed: 1926-07-02
Abstract: 278,418. Dawson, J. C., and Canadian American Machinery Co., Ltd. July 2, 1926. Folding paper.- Sheets printed with more than one signature up are folded in a machine provided with a feeding-unit which immediately after the operation of cutting each sheet into its separate signatures separates the signatures so that they pass in succession to the same folding- units. As applied to a buckling-folder machine of the kind described in Specification 14893/14, a sheet printed two signatures up is given two parallel folds and a cross-fold and passes from the delivery rollers G, Fig. 10, of the cross-folder between cutting-discs h to rollers i, i<1>, which feed it at right-angles to its previous path in the usual way. Instead, however, of the rollers all rotating at the same speed, the rollers i<1> above the level of the discs hare driven at a speed slightly less than that of the rollers i so that the signature s<2> engaged by them is, for a short period, fed forward at a slower speed than the signature s<1>, and consequently the signatures are spaced from one another. To effect the reduction in speed, the shaft of the roller i is coupled to that of the roller i by reduction gearing comprising pulleys a m, m<1> and a driving belt l. The signatures proceed through feed-rollers H, J to a cross-feeder n, Fig. 9, from which the signatures pass successively through the last folder K, L, M, to a delivery table O. As an alternative arrangement the sheets may be fed at a higher speed after leaving the discs h than before reaching them, so as to effect the required separation. Specifications 24301/13 and 8774/14 also are referred to.

IPC: A61L17/14
Filed: 1966-04-18
Abstract: Sutures are prepared by melt spinning a polylactide to form a filament, preferably a monofilament.  Alternatively the polylactide may be melt extruded to form a sheet which, after drawing, may be sub-divided to form sutures.  The polylactide has an inherent viscosity of at least 1.0 in a 0.1% solution in benzene at 25 DEG C and the filament is drawn at a draw ratio of 5:1 to 11:1 in a liquid which is non-toxic toward body tissue, is a non-solvent for the polylactide and is maintained at a temperature of 80 to 140 DEG C. The freshly extruded filament may be quenched in a liquid such as water prior to being drawn and the quenching liquid may be maintained at a temperature below 50 DEG C.  The polylactide may be extruded at 185 to 215 DEG C.  The filaments may be drawn in glycerin. The drawing liquid may be maintained at 90 to 135 DEG C.  The product of the draw ratio and the inherent viscosity of the polymer may be a number not exceeding 23, preferably not exceeding 20.  The filament may be drawn in two stages, the draw ratio in the first stage being from 4.0:1 to 6.2:1 and in the second stage from 1.5:1 to 2.5:1, the temperature of the liquid in which the filament is drawn being from 80 to 100 DEG C in the first stage and 100 to 130 DEG C in the second stage, the overall draw ratio being from 5:1 to 11:1.  The polylactide may have a predominance of one antipodal species of a -hydroxy propionic acid and may be made from the cyclic esters of the hydroxy acid derived from pure D(-) or L(+) lactic acids.  An example of a class of polylactide copolymers within the above definition is a copolymer containing up to about 15% by weight of repeating units having the general formula <FORM:1101766/A5-A6/1> wherein R is a lower alkylene, m is O or I, R1 is hydrogen or lower alkyl, R11 is hydrogen or alkyl of up to 22 carbon atoms when m is O and hydrogen or lower alkyl when m is I, and can be the same as R1 or different.
