Patent DE-3327944-A1 (DE)
Title: Non-rigid hot-air airship with turbo prop drive
Inventor: SCHULZ WALTER
IPC: B64B1/62
Filed: 1983-08-03
Abstract: A non-rigid hot-air airship with a turboprop drive can be used as an airborne advertising hoarding for daytime and nighttime advertising flights. The streamlined nylon balloon ship's hull has divided chambers which are open underneath, and the balloon space is connected to the nozzle overpressure control flap behind the gondola. In addition, in each case one turbine engine is fitted which, with the adjustable heat distributors, blows the lifting hot air into the respective balloon chamber, and the propellers which are coupled in at the same time drive the hot-air airship to provide its own movement drive. During take-off preparations, the balloon ship's hull can be inflated only by its turbine set using the propeller air, after which only heat blown in from the turbine is then used. In the event of a fully hot or cold air supply, the airship rises or falls on the spot as a result of which a high manoeuvring capability is made possible during takeoff or landing. If severe weather suddenly occurs, the flexible non-rigid hot-air airship is quickly deflated, packed together and can be moved to a fine-weather area in order to carry out new operational advertising flights. The transparent nylon balloon can be transilluminated from the interior during darkness, and the production surfaces of the balloon inner sides allow slides, illuminated moving lettering or multi-coloured moving airborne image advertising to be projected.

Abstract: UV-curable surface-coating (paint, lacquer, enamel) systems are proposed which, in addition to a UV-curable constituent, contain a two-component constituent. The UV-curable constituent comprises one or more prepolymers, one or more reactive thinners and a photoinitiator or an initiator mixture, and the two-component constituent comprises one or more epoxy resins and one or more amide curing agents or one or more polyols and one or more isocyanic curing agents. These surface-coating systems are distinguished by the fact that they require only very short curing times, consume little energy during curing, and are environmentally friendly. They are also and in particular suitable for heat-sensitive parts. In addition, a wide range of starting materials can be employed for these surface-coating materials, so that a very considerable degree of freedom is available with respect to properties and colour of the surface-coating film produced.

Title: Process for producing metal electrodes on a foil
Inventor: BARTSCH WOLFGANG DIPL PHYS
IPC: H01L41/29
Filed: 1983-12-09
Abstract: In a process for producing metal electrodes for piezoactivated regions (4 to 6) in a foil (2) to which electrical connection leads (20, 21) are assigned, according to the invention, a first very thin metal layer (31) made of aluminium, a second metal layer (32) which acts as an adhesion promoter and a soldering and etching resist, and a third metal layer (33) which is used for connection are consecutively deposited on the surface of the foil (2). The third and the second metal layers (33 and 32) are then removed again in a first lithographic etching process in those regions which are not needed for the electrical connecting conductors (20, 21). In a second lithographic etching process, those parts of the first metal layer (31) are removed which are not to be activated piezoelectrically. This process produces a metallisation which makes possible an inseparable connection to electrical connecting conductors (21, 22) and a high piezo constant is obtained in the piezoactive regions (4 to 6). <IMAGE>
