Title: Adhesive labels for e.g. library books - have marking applied to paper which is barrier to plasticisers and which is coated on the back with plasticiser-free adhesive
IPC: G09F3/02
Filed: 1990-07-25
Abstract: A label for providing books with signatures, reserving details etc. has a base paper with a coating of adhesive on the back; the paper is impervious to plasticisers and the adhesive used is free from plasticiser.  Prefd. adhesives are acrylic and acetate. ADVANTAGE - Neither the label nor its written details are damaged by the book cover. The label cannot be removed and stuck into other books. In an example, an adhesive-coated label (2) on a non-stick backing (1) has a main paper layer (3) to take an  (e.g.) library marking (4). The other side of the paper (3) has the adhesive which, although readily stripped off its original backing (1), will adhere to the back or cover of the book. The paper mass contains additives to resist plasticisers and also the label has the layer (7) which resists plasticiser. In use the suitable paper sizes are stamped out (but not the non-stick backing) and are given the desired markings etc. by hot embossing. The stripped labels are then hot pressed on to the books, whereby the adhesive softens and adheres when cold. Although the labels can be removed hot they tear in the process and hence cannot be reused.
Patent DE-4024659-A1 (DE)
Inventor: MUELLER HEINZ
IPC: C09K23/08
Filed: 1990-08-03
Abstract: Described is the use of environmentally compatible surface-active alpha -sulfo fatty-acid di-salts as emulsifiers of the water-in-oil or oil-in-water type in fluid, pumpable bore-flushing agents or other borehole-treatment fluids which have a closed or disperse oil phase as well as an aqueous phase and which are suitable for the non-polluting exploitation of natural deposits of e.g. oil or gas.

Title: Special design optical head assembly - uses internal reflection properties of prism to ensure accurate deflection of light beam
Inventor: FUJITA SHUICHI
IPC: G11B7/135
Filed: 1991-02-13
Abstract: The light source and photo-detector unit (3) produces a beam of light parallel to the radial reference line (2) of an optical disc (1) under test. On entering the movable carriage assembly (4) the light beam is deflected vertically upwards by the internal deflecting surfaces (402) of a prism (4A) and passes through a condensing lens (4b) before striking the optical disc (1). The optical disc (1) reflects the light beam back along the identical path. Any light beam deviation caused by optical disc (1) surface tracking errors are registered by the photo-detector. USE/ADVANTAGE - Optical head prism action ensures that light beam is deflected vertically regardless of any misalignment introduced by optical movable carriage assembly.
