Title: Acoustic DF for underwater detection systems - has multiple detectors with linear combination matrix and dipole characteristic
Inventor: SCHWANTKE GOETZ DR-ING
IPC: G01S3/805
Filed: 1971-06-26
Abstract: The acoustic direction finder for underwater detection systems uses four pressure sensors, each having a spherical polar response. The detectors are placed at the corners of a tetrahedron. The output signals of the detectors are combined in a linear fashion to produce a dipole type directional characteristic. So that the direction finding device is independent of the position of the vessel on which it is mounted e.g. submarine, a vertical reference plane is provided by a universally-mounted pendulum or other device. The output signal from the combining matrix is normalised by the summed signals of all the detectors. This produces a directional signal which is independent of the intensity of the source.

Title: Domestic refuse press with detachable ram plate - has horizontally removed ram plate and locking feature
Inventor: HERMEIER WERNER
IPC: B30B15/06
Filed: 1973-11-13
Abstract: The press ram plate of the domestic refuse compactor is removed for cleaning purposes. The ram plate is connected by horizontal sliding guides to the press ram and the plate is disconnected by sliding it sideways out of the ram end. The press ram has at its lower end a press plate which is held on the ram lower end by projecting lugs and pins. The pins engage with hole in the ram end and hence the ram and plate are firmly connected in a vertical direction. The pins are of unequal length so that when the press plate is pushed against the force of the spring the shorter pins disengage with the hole in the ram end the plate can be tilted downwards and the longer pins will then be disengaged. The plate is locked by a bolt on the ram. This bolt ensures that the plate is not inadvertently displaced on pressing.
