Title: Capacitive action keyboard - with spaces between metal oxide vapour deposit keys used for peripheral keys
Inventor: PRETZSCH SIEGFRIED
IPC: H03K17/96
Filed: 1979-06-18
Abstract: The keyboard has keys formed by metal oxide vapour deposition on a glass or organic glass plate for use as a capacitive finger contact switch and must keep adequate space between the square keys to prevent mutual interference. These spaces can be turned to good use if between adjacent and diagonally opposite keys additional peripheral keys are arranged. A set of four keys in a square is thus transformed into a field of nine keys, and one of sixteen keys into one of forty-nine. The four basic keys (10), representing metal oxide vapour deposits on a glass plate are divided from each other by clear spaces. These spaces are now used for peripheral keys (20) so that five additional functional keys have been gained.

Title: Non-woven fabric impregnation with emulsion-de-stabiliser - before applying acrylic! latex emulsion to form coagulated coating preventing hair emergence
Inventor: MARANGHI MARCO
IPC: D06M15/263
Filed: 1979-07-03
Abstract: Hair protrusion to non-woven fabric surface is prevented by coating with a thin acrylic resin emulsion or acrylonitrile polymer latex emulsion layer after impregnating the carrier with an emulsion-destabiliser which causes emulsion coagulation on resin contact with the fabric. Pref. emulsion-destabiliser is a electrolyte in aq. soln. A hair-free surface is obtd., e.g. suitable for dusters. Emulsion coagulation on surface stops resin from penetrating into fabric and forms a skin which prevents hair emergence. The articles also have increased flexibility, softness and bulk.

Title: Two=stage pyrolysis of coal - using by=produced coke as heat carrier and for water gas generation
Inventor: TSCHUCHANOV SINOVIJ F
IPC: C10J3/62
Filed: 1979-08-09
Abstract: Prodn. of gaseous and liq. products from particulate coal (or other solid fuel) is carried out by drying followed by 2-stage pyrolysis. Part of the particulate coke formed during pyrolysis is recycled as heat carrier to the drying unit, the rest is heated to 800-1500 deg.C by contact with hot gas and/or by partial combustion. The heated coke is then sepd. from gases and gasified with steam from the drying unit. The resulting water gas is sepd. from the residual coke, which is recycled as heat carrier to the 1st. stage pyrolysis reactor. The process has a high energy efficiency (84-88%) and gives high prod. yields without pollutant emission and without formation of slag deposits in the system.

Patent DE-3017820-A1 (DE)
Inventor: SCHULTE GERD
IPC: G03B35/10
Filed: 1980-05-08
Abstract: Contrary to stereoscopic picture shooting apparatuses known heretofore, provided with at least two lenses, the apparatus according to the invention allows the obtention of stereoscopic images already mounted and insensitive to height errors, or a large size particularly appropriate for the projection thereof and which are compatible with conventional projectors allowing a utilization of the size and a maximum light yield. The individual images (12) are orientated in the same direction, one over the other, in a large size of about 1:2, 35, by means of reflecting mirrors and prisms known per se. The images are separated by a separation band (4) the width of which is at least 10% of the total length or width and is used particularly for recording data, the images forming a square surface with the separation band (4). For the first time in a photographic apparatus of a general use, it is possible to record automatically for each stereoscopic shot the date, place and other data without any detrimental influence on the image and subsequently to project the desired images. The new image sizes, of interest for the plane photography where they do not require any roller for series shots, allow the use of conventional reel films resulting in extremely good images of stereoscopic shots with ideal projection caracteristics.
