Title: Fixing toner images in a copying machine
IPC: G03G15/20
Filed: 1979-10-18
Abstract: A support member 15, such as a sheet of paper, carrying toner images 16 on a surface thereof is passed through a nip between a first heated roll 1 and a second roll 4 in pressure contact with the first roll 1, so that the toner images 16 are fused on the support member 15. In order to minimise adherence of the toner images 16 to the first roll 1 the electrostatic charges on at least one of the rolls and/or the toner images are modified, for example by means of a corotron 17, so as to increase the electrostatic forces acting on the toner images in the direction of the support member. This can be achieved, for example, by decreasing the electrostatic attraction or increasing the electrostatic repellancy between the first roll and the toner images, and/ or by decreasing the electrostatic repellancy or increasing the electrostatic attraction between the second roll and the toner images. <IMAGE>

Title: Process for the Manufacture of Texturized Polyester Yarns Having Improved Mechanical Properties
IPC: D02G1/02
Filed: 1979-12-03
Abstract: A process for manufacturing texturized polyester yarns from preoriented polyester yarns comprises imparting to the yarns a false twist (13) and concurrently drawing them (11-14) while heat setting them (12), subsequently subjecting them to a second heat setting (15), and collecting the texturized yarn (18). The temperature of the heat setting means and the speeds of the means which impart to the yarns their motion are subjected to critical conditions. Namely, the temperature of the first heat setting means is lower than 200 DEG C, the temperature of the second setting means is not higher than that of the first heat setting means and is preferably lower and the yarn undergoes a retraction, preferably between 8% and 16%, during the second heat setting. Preferred temperatures are 190 DEG C for the first heat setting means and from 160 DEG C to 190 DEG C for the second heat setting means. The texturized yarns thus obtained have increased elongation and tenacity and are greatly improved as to crimp rigidity and crimp contraction. <IMAGE>

Title: Security in electronic fund transfer systems
IPC: G07F7/10
Filed: 1981-01-30
Abstract: A technique for moneyless small cash transactions by means of an electronic purse device with contactless data transfer is described from the point of view of overall systems performance using changeable genuity test data, in accordance with British Patent Application 8028824. It is shown that a genuity test of the described kind must apply not only to the mutual testing of the purse or pay device and the point of sale terminal but also as between the latter and the bank computer to which sales point takings are to be electronically transferred. Guide lines are given how attempted fraud can be met by using a sequential number incremented by one with every transaction and which is counterchecked by the Banks Computer. In combination with location codes uniquely attached to transaction terminals, attempted fraudulent action would be rapidly discovered. The remote but feasible possibility of a person meddling with his account number to avoid being debited for purchases made, is met by a linkage established between said number and the variable test number in such a manner that any incongruity due to changed account numbers would be discovered at the sales terminal itself. <IMAGE>
