Patent DE-4101214-A1 (DE)
Title: Prodn. of reusable adhesive labels - by applying tiny quantity of silicone to e.g. PVC printed film and then e.g. dispersion of polymer adhesive in the form of pattern of dots
Inventor: SCHULZ-SORAU CHRISTIAN
IPC: C09J7/22
Filed: 1991-01-17
Abstract: An adhesive label, and particularly one made of plastic films, is produced with the adhesive on one side and it can be affixed repeatedly; a liquid silicone is added to the adhesive which is then applied in a grid pattern. The films are preferably PVC printed with advertising material. A very small quantity such as one drop of a liquid silicone has a very great effect when added to the amount of adhesive for 1 m2 or surface. An advertising PVC film can be then be applied, stripped off, and re-applied as many times as desired, without any traces being left on the surface. The adhesive is best applied then in the form of a grid pattern of dots. The dots concerned can be four of dia. 3 mm distributed per 1 cm2 of film. When the material is applied to a surface any entrapped air can then readily escape. The recommended adhesive is an aq. dispersion of a polymer, as this clearly has no undesirable effect on the environment. The dispersion can be diluted with distilled water. The resultant labels can be assembled in a block from which they can be stripped off individually, applied to the substrate in question, and if necessary removed and replaced in the block of stacked labels. ADVANTAGE - The label is preferably silk-screen printed and it can be removed again from a substrate without leaving any residues behind. It can then be affixed aga mm

The first lazy contact (8) of the change-over switch is connected with the other end of the component (39). The second working contact (12) is connected to a second mains terminal (14). The two change contacts (6,7) are connected to the effective part of the field winding (3) in a braking mode. The starting capacitor lies between the second rest contact (9) and the mains terminal (13) and a circuit (27) controls the electronic component (39). ADVANTAGE - Suitable for braking universal motors reliably without extra components. Capacitor lies parallel to field winding in braking operation so that it prevents transitory interruptions in current through armature leading to collapse of self-excitation.
