Patent DE-2111314-A1 (DE)
Title: Guide unit for fancy threads on industrial sewing machines
Inventor: PERCIVALDI MANSUETO
IPC: D05B53/00
Filed: 1971-03-10
Abstract: A holder and a carriage which may be moved to-and fro in relation the needle are fastened to the sewing machine. Hinged to the carriage is a swivel arm, with a fance thread guide, which is fastened at one end only, and guided in a curved path in relation to the axis of the machine. An associated drive moves the free end, and the carriage in such a way, that the insertion point of the needle with the sewing thread is just in front of the crossing point of the machine axis and the fancy thread. The guide is for sewing machines, which fasten fancy threads, borders, and similar, onto leather, fabrics, or synthetics. The guide is of simple construction, and allows the fixing of much thicker threads than before.

Title: Rotary offset printer dampening unit - one roller does not contact plate cylinder while distributor surface picks up ink
Inventor: KALTENSTADLER OTTO
IPC: B41F7/26
Filed: 1973-08-31
Abstract: The design permits the dampening fluid to be directly fed by the centrifugal or other feeder to both dampening rollers and thus provide a short travelling distance without many gaps. In one position, a dampening roller is out of contact with a plate cylinder but transfers the dampening fluid to a lower inking roller via a transfer roller. During the short non-printing period, four inking rollers are moved away from the plate cylinder, and the transfer roller is also detached from inker. Metered application of dampening fluid to the plate cylinder is then achieved by controlled timing of drive of a thrower. With the return of contact of the dampening roller with the plate cylinder, the normal setting of inkers is restored, similarly to the resetting of contact between the transfer roller and inker.
