Patent WO-8300127-A1 (WO)
Inventor: MEYER URS P
IPC: B63B35/79
Filed: 1982-07-02
Abstract: The floating body (1) comprises a stiffening rib (3) embedded, in the longitudinal axis of the floating body, into a body of a porous material (2) of polyethylen or polystyrol foam. The rib (3), which is set on edge and has a uniform width, has a height which gradually decreases from the middle of the floating body towards its ends. The rib (3) consists of a core (4) comprising reinforcement layers (5, 6) of glass fibers on its upper and lower sides. The floating body thus produced has an extremely light weight of about 9 kg and shows very good steering properties, especially as a glider. Owing to the construction and the shaping of the rib (3) it is possible to obtain a stiffness distribution independent of the external shape of the floating body.

Title: Telephone connection control circuit - has line encoder whose control potential initiates supply signal of opposite polarity to subscriber terminal voice line
Inventor: BUDNIK NORBERT
IPC: H04K1/00
Filed: 1969-09-09
Abstract: The control circuit, for a telephone connection with voice coders, is improved by allowing each subscriber to check before or during connection whether the coder is available for his terminal. The first control potential in the coding device that connects to the lines, applies a supply signal to the subscriber terminal's voice line of opposite polarity to the exchange supply. This supply signal is applied when the voice coder is able to be engaged. A rectifier is connected between the voice lines in the subscriber terminal via an indicator and forms a D.C. circuit carrying the reversed polarity.
