Title: Hi-fi loudspeaker box - has omnidirectional characteristics produced by groups of loudspeakers in five faces
Inventor: POENSGEN KARL OTTO
IPC: H04R3/14
Filed: 1974-10-17
Abstract: The hi-fi loudspeaker box produces omni-directional characteristics resembling those of the original sounds by direct conversion using loudspeakers for the three directions. The loudspeakers occupy the front, rear, sides and top of the loudspeaker box and are connected by active or passive coupling networks. Each face may therefore contain one or more loudspeakers arranged in line or otherwise grouped. Two such loudspeaker boxes can be used to produce stereophonic sound. The advantage of the loudspeaker box lies in its direct sound reproduction. In one embodiment the base frequency response speaker (6) is installed at the front of the box and connected to a frequency divide path.

Title: Discriminator for periodical signals - superimposed on stochastic signals by auto-correlation function produced in correlator for analyser
Inventor: ROTHAERMEL DIETER
IPC: G01B7/12
Filed: 1975-11-14
Abstract: Discriminator for stochastic, periodical or stochastically superimposed periodical signals feeds the signals at time-dependent electrical voltage signals to a correlator. The latter produces by integration an autocorrelation function which is passed as a function of the signal delay time into an analyser. Discriminator may be used in dia. or cross-section sensor systems for the thread in spinning looms. Stochastic dia. fluctuations are therefore passed without interference. Periodical fluctuations which would produce a moire effect in the finished article are detected and the loom is stopped.
