Title: Rig in wing form for vessels furnished with sails
Inventor: SCHOLZ LUDWIG
IPC: B63H9/06
Filed: 1981-02-11
Abstract: The wing rig consists of the wing nose (2), which, according to Fig. 1, is set up like a mast in such a way as to be rotatable about the vertical axis, and of the wing flap (3) adjustable on both sides. The outline is rectangular and corresponds to a perpendicular vessel wing. In cross-section, the wing nose and the wing flap, according to Fig. 2, are symmetric. By the adjustment of the wing flap, the symmetric wing profile is turned into an asymmetric wing profile, according to Fig. 3, similar to that of an aircraft wing, with a cross-section producing lift or propulsion. The flap angle is limited by lateral locking devices, adjusting devices enabling the flap angle to be changed and thus the rig trimmed. The wing rig can not only be mounted in a fixed position - but rotatable about the vertical axis - on boats, ice yachts and sand yachts but can also be used as a sailboard rig provided with lateral handles and a universal mast-foot joint. The advantage over conventional canvas rigs lies in higher efficiency and in the ability to sail closer to the wind due to the flat windward side and the absence of the aft canvas-sail part causing dynamic pressure. <IMAGE>

Title: Arrangement for transmission of indication signals, in particular alarm indication signals
Inventor: SCHLOEGL KURT
IPC: G08B1/08
Filed: 1982-02-02
Abstract: For transmission of alarm indication signals, in particular alarm signals from a message generator (1) via a transmission channel (5, 7, 9) to a message receiver (3), indication signals generated by indication signal generators (11) are transmitted together with identification signals which are generated by an identification signal generator (21, 27) of the message generator (1). The message receiver (3) evaluates both the message signals and the identification signals. The message generator (3) also has an identification signal generator (25, 31) and, like the identification signal generator (21, 27) on the message generator side, transmits a plurality of different identification signals via the transmission channel (5, 7, 9). On receiving each of the identification signals of the identification signal generator (25, 31) on the message receiver side, the identification signal generator (21, 27) on the message generator side transmits an identification signal constantly allocated to the received identification signal. A random generator (29) controls the temporal succession of the different identification signals transmitted by the identification signal generator (25, 31) on the message receiver side in randomised fashion. This renders the alarm indication system, particularly one using public telephone lines as a transmission channel, more secure against tampering. <IMAGE>
