Filed: 1958-10-22
Abstract: 870,815. Printing machines. RITZERFELD, W., and RITZERFELD, G. Oct. 22, 1958 [Oct. 25, 1957], No. 33739/58. Addition to 827,772. Class 100(2) In a rotary duplicating machine as claimed in Claim 1 of the parent Specification, by forward movement of a control lever through gating means a driving motor is switched on the moistening mechanism, the inking mechanism, and a counter pressure roller are brought step by step into their respective operating positions and a paper feeding mechanism is started. The lever 92, Figs. 1 and 5, is mounted on a stud 54 and is movable in a slotted quadrant 42, being urged against an abutment 43 by springs 118, 119. When the lever is manually moved to a gate 44, a switch 93 is closed to start a motor driving the printing drum 1, Figs. 1 and 6. Through a system of levers and cams shown in Fig. I, when the lever 92 is moved to a gate 45, a damping roller 17 is moved against a friction roller 18, and ink transfer rollers 2 and 3 and an inking roller 5 are moved against a friction roller 4. When the lever is moved to a gate 46, which is provided by a retractable bolt 127, the roller 17 is moved against the drum I, while still contacting the roller 18. When the lever is moved to a gate 47, the rollers 2 and 3 are moved against the drum 1, while still contacting the roller 4. When the roller is moved against an abutment 48, a counter pressure roller 99 is moved against the drum 1, and is locked in such operative position by an armature 70 of an electromagnet 70a engaging a surface 69 of a control plate 68. The movement of the roller 99 also acts through a lever connection (not shown) to couple the drum 1 to an eccentric wheel and reciprocate a sheet feeding member 106. The lever 92 is then released by the operator and is brought back by the spring against the bolt 127, the machine continuing to operate normally. When the magnet 70a is energised by means of a paper feed failure detecting means, the plate 68 is released and the roller 99 is moved away from the drum 1 by the spring 119. The movement of the roller 99 causes a contact 120 to close for a short time, to energise a magnet 123 and withdraw the bolt 127 long enough to allow the lever 92 to be retracted to the gate 45, thereby withdrawing the rollers 2, 3 and 17 from the drum.

Title: Process of producing latently crimpable yarn
IPC: D01D5/32
Filed: 1970-07-10
Abstract: 1308998 Crimpable yarns ALLIED CHEMICAL CORP 10 July 1970 [10 July 1969] 33741/70 Heading B5B [Also in Division D1] In a process for producing latently crimpable yarn, a splittable, elongated mass formed from a matrix of one thermoplastic polymer with one or more polymers that are incompatible with it disperced in it, is subjected to a rolling pressure applied progressively along its length and then to a transverse force gradient, the rolling pressure being sufficient to enable the transverse force to split the structure longitudingly into a yarn composed of fine filaments. During this process, the mass is maintained in a semiamophous condition by keeping it below the glass transition temperature of at least one polymeric component of the blend. The elongated structure may be a tape or a monofil or a thin film and may be round. It may be prepared by extruding from a melt. If at least one of the component polymers is capable of molecular orientation, the structure may be stretched. The rolling pressure is applied along the length of the structure and, if a round or near-round structure is used, the pressure is suitably sufficient to reduce one transverse dimension by at least 30% preferably by 50-80%. If a tape is used it need only be above 10%. The rolled structure is then subjected to a transverse force gradient by such means as twisting, flexing, &c. to split it longitudinally. Preferably the force is generated by impelling the structure against a deflecting surface by means of a high velocity gas stream, in which case a suitable arrangment is to introduce the stretched structure into the side of the gas stream which impels it through a tube to a cylindrical surface. Crimp may be induced by treating the yarn whilst under a tension of no more than 0À1 gm. per dinier with a hot gas or liquid or a swelling agent. Examples illustrate the process for polycaproamide blended with polyethylene terephthalate and/or polypropylene formed into a monofil. Reference has been directed by the Comptroller to Specification 1,108,151.
