Title: Multichannel signal transmission system - is for SSB modulated carriers and uses carriers that are integral multiples of fundamental
Inventor: DIETRICH WERNER DIPL ING
IPC: H04J1/06
Filed: 1976-07-01
Abstract: The multichannel transmission system is for SSB modulated carriers. It has all carrier frequencies arranged as an integral multiple of a fundamental frequency which is present or obtainable at all points in the transmission system. The carrier frequencies needed for modulation and demodulation are derived by dividing, multiplying or mixing (and subsequent filtering) the fundamental frequency using non-linear elements. The advantage of using carrier related in this way lies in reducing the number of components and the cost of system.

Patent DE-2731163-A1 (DE)
Inventor: QUICKER HERBERT
IPC: E05F17/00
Filed: 1977-07-09
Abstract: In order to be able to open both parts of a double window either by tilting or pivoting, it is known to connect the inner sash and outer sash to one another via two connecting struts, by means of which the two window sashes are coupled together. However, it was necessary to provide special release mechanisms for the pivot and tilt bearings, which release mechanisms additionally had to be actuated. The invention proposes the design of a double window in which it is possible to effect a pivot and tilt movement and to lock the window in the closed position simply by actuating a window handle. To this end, a third connecting strut (19) is provided between the inner sash (3) and outer sash (2), which connecting strut (19) is secured in a fixed manner on one window sash and secured on the other in a releasable manner by means of horizontal movement. In addition, the outer sash (2) is connected to the storey frame (1) by means of a concertina arm (23) which forms the upper pivot axis (28) of this window sash. The concertina arm (23) can be swivelled together with the window sash (2) at its one end and is connected at its other end by a spring catch connection (25, 26) which can be released under tension. <IMAGE>
