Patent DE-3744000-A1 (DE)
Title: Method and device for printing, in particular on elastic textile webs
Inventor: AFFUEPPER HANS
IPC: B41F15/08
Filed: 1987-12-24
Abstract: The invention relates to a method and a device for printing on printing materials, in particular on elastic textile webs, the printing material being transported stepwise by a particular length over a printing table by being carried along by a transport belt and being fixed by stopping the transport belt to carry out a printing operation. It is known to transport and to fix the printing material by means of a double-sided adhesive tape stuck to the transport belt, as a result of which, however, no constant printing results can be achieved. To improve the printing quality and to increase production, according to the invention, the printing material is now carried along and fixed by the transport belt by applying negative pressure to it.

Title: Meterable liquid dispenser
IPC: G01F11/02
Filed: 1988-06-07
Abstract: The invention relates to a meterable liquid dispenser, in particular soap dispensers, and the aim is to prevent after-dripping of such dispensers and the reduced operational capability in the case of poor viscosity of the liquid. This is achieved by the combination of a pressure piston which moves into a metering chamber and mechanically closes the dispenser opening via a closing bolt, and a non-return valve for filling the metering chamber. The metered quantity delivered can be adjusted continuously via an adjusting screw, a bypass bore between the non-return valve chamber and the supply container having to be opened or closed. The liquid dispenser can be operated with a lifting magnet which is switched in a contactless manner. <IMAGE>

Title: Electrophotographic printer
Inventor: NARITA MITSURU
IPC: G03G21/08
Filed: 1989-01-19
Abstract: An electrophotographic printer contains a photoconductor having a conductive substrate, a charge-carrier transport layer on the substrate, a charge-carrier generation layer formed thereon, and a coating layer which coats the latter layer. The latter comprises As2-xSe3+x, where x is from 0 to 0.5. This coating layer is particularly wear-resistant. For electrophotographic printing, the photoconductor is electrically charged, exposed and developed, the toner image is transferred to paper, and the photoconductor is then irradiated with light in order to remove residual charge carriers. In order to avoid black streaks and fog on the copy to enable good print quality to be obtained, the removal of electrical charge is carried out with light having a wavelength of less than 680 nm.

Inventor: TISCHER WILHELM DIPL ING DR
IPC: C12N11/08
Filed: 1990-04-05
Abstract: A water-soluble saccharide-modified protein conjugate is covalently bonded via a saccharide group to a hydrocarbon backbone. Such saccharide-modified protein conjugates can be prepared in a straight-forward manner by polymerising a vinyl saccharide and conjugating the resulting poly(vinyl saccharide) with the protein, which is preferably an enzyme, in a manner known per se. While having high enzymatic activity, the protein conjugates according to the invention are also stable in aqueous solution over a long period and are therefore particularly suitable for use in assay kits.
