Patent DE-2719773-A1 (DE)
Inventor: CASCIANELLI CARLO
IPC: B29C70/16
Filed: 1977-05-03
Abstract: In this process a core mould is used onto which the fibre material is wound to form a wound body. Subsequently an outer casing consisting of material impeding heat transmission, preferably cellulose paper, plastic paper or plastic film, is applied temporarily onto the wound body, for example by winding, it being possible to introduce a release agent between the wound body and the outer casing. For vacuum impregnation, the end faces of the wound body are sealed and the air disposed in the wound body is sucked out from one end face of the wound body, an impregnating resin being forced into the wound body walls from the other end face at the same time. After the wound body is cured, the mould core is pulled out and the outer casing is removed as far as the impregnated outer surface of the wound body formed as a hollow body. This process is advantageously suitable for small series production without using a complicated metal mould or an impregnation bath.

Title: Antiseptic dental stopping paste - contg. a non-coagulant antiseptic, a setting agent and a setting retarder
IPC: A61K6/02
Filed: 1978-04-17
Abstract: New pastes for treating the interior of teeth to seal dental channels and holes comprise (a) an non-coagulating antiseptic, (b) a prod. mixt. to ensure setting, and (c) an agent which retards setting and lowers the final hardness. Typical pastes contain (a) ca 4-8% parachlorophenol-camphoras antiseptic, (b) ca 22-24% eugenol and ca 48-58% zinc oxide as setting agent, and (c) ca 12-18% diiodothymol as setting retardant. Since the antiseptic is not absorbed via dental channels the antiseptic action is long-lasting. Because of the extremely slow setting of the pastes, they are easy to insert and give good sealing of the apex and minor channels. Adhesion to channel walls is good, but the pastes can readily be removed when necessary.

Title: Fluorescent lamp starting circuit - has thyristor and RC circuit overriding conventional discharge-type starter to provide quick starting
Inventor: RABL HELMUT DIPL ING
IPC: H05B41/04
Filed: 1978-08-23
Abstract: The starting circuit has a conventional discharge starter in parallel with the lamp (11). The lamp is connected via a ballast inductor (12) to the a.c. supply. A capacitor (2) is connected in parallel with the lamp. To ensure that the lamp starts quickly a thyristor (g) is connected in parallel with the capacitor. The thyristor's gate is coupled to an RC circuit comprising a resistor (3) in series with a second capacitor (4) across the first capacitor (2). A large preheating current is generated immediately after switch-on and ensures that the lamp starts quickly without the starter having to come into operation. Only when the mains amplitude is inadequate for starting does the starter come into operation, e.g. after a one second delay. A PTC resistor (7) may be connected between the lamp and the first capacitor to ensure that the ballast inductor is not overloaded or damaged at the end of the lamp's lifetime or if a fault occurs.
