Title: Process for selective transfer of metallic foils to xerographic images
IPC: G03G8/00
Filed: 1986-02-05
Abstract: The present invention is directed to a method for selectively transferring metallic foil to xerographic images on a receiving substrate such as paper. The method generally comprises providing a transfer assembly including a metallic film and a receiving substrate including xerographic images disposed thereon. The receiving substrate is placed in face-to-face contact with the transfer assembly to form a sandwich with the xerographic images on the inside. The sandwich is then fed through an apparatus, where heat and pressure are applied, causing the xerographic images to tackify and causing the metal film from the transfer assembly to selectively adhere to the xerograhic images.

Title: Disposable absorbent article
IPC: A61F13/15
Filed: 1987-04-13
Abstract: In a disposable absorbent article, such as, in particular, a nappy, in which an absorbent body (1) is covered on one side by a non-liquid-permeable protective film (2) and on the opposite side by a porous covering layer (3), certain edge regions of the porous covering layer are to be provided with a non-liquid-permeable blocking layer. 
<??>Said blocking layer is constructed as a prefabricated sealing film (4) and has, prior to application to the covering layer (3), on the one side a smooth surface and on the other side an extremely fissured surface. The sealing film (4) serving as blocking layer penetrates into the covering layer (3) essentially solely with the fissured surface regions. Absolute tightness is guaranteed by the smooth surface of the sealing film (4). Due to the physical bonding between the sealing film (4) and the covering layer (3), the sealing film can be of extremely thin construction, i.e. it requires only an extremely small amount of material. 
<??>Special production methods are specified for the only partial penetration of the sealing film (4) into the covering layer (3).

Title: Display device
IPC: H04N3/12
Filed: 1987-09-18
Abstract: The liquid crystal display unit 1, has a video signal receiver 2 and a store 3. Time-modulation grey-scale addressing of the ferroelectric liquid crystal pixels in a display panel 4 is provided to a store 10 which records the number of changes of state for each pixel during one picture-signal. Once the most-significent bit has been processed and is being displayed on the panel 4, the change-of-state store 10 has the net number of changes which the pixel has undergone in that picture. Controller 11 causes store 10 to output the value appropriate to that pixel and pass it to driver unit 9 to produce a compensating pulse (whether positive, negative or zero) necessary to ensure that there is no net electrical potential over the entire picture interval. The display produced by the compensating pulse is cleared immediately the first data of the next picture is input to the pixel. Assuming that the LSB of the data for a pixel already on display in panel 4, then in the next scan extractor 6 passes the next LSB to comparator 7 whose other input is connected to a pixel-state store 8. Accordingly, the new bit-value is compared with the existing state of the pixel, and comparator 7 passes on an instructing signal to pixel driver unit 9 only if the state of the pixel requires changing; in such an eventuality, the driver unit 9 issues an appropriate monopulse select voltage. Comparator 7 also passes such an instructing signal.

Title: Method and device for cleaning the cylinders in a rotary press
IPC: B41F35/00
Filed: 1989-12-08
Abstract: When washing the cylinders in a rotary press, there is a problem that cleaning liquid passes over the web of printed material running off into the drying route with an ignitable atmosphere. According to the invention, the cleaning of the cylinders takes place according to the specification of the measured gas/vapour concentration established in the dryer. At a value below the permissible gas concentration value, an amount of cleaning liquid can be added until the differential amount up to the permissible value has been used up. It is possible for the flow of the metered addition to be applied in partial quantities distributed virtually simultaneously over the washing bar, it also being possible for the web and print covering to be calculated. The permissible value can also be approximated by the fact that the moisture of the cleaning surface and/or of the web is controlled as an auxiliary measure. Via the correlation between the flow of metered addition and the gas concentration arising therefrom, automatic adaptation of the guiding system is possible so that complex safety tests are not necessary when a cylinder cleaning system is installed in a press with a dryer. The metered addition of cleaning liquid which is oriented by the threshold value reduces the duration of cleaning and saves wastage, it being possible, in particular, specifically to remain below the lower explosion threshold. <IMAGE>
