Patent DE-3627960-C1 (DE)
Title: Monitoring device for loudspeaker installations
Inventor: GOLLNOW CHRISTIAN
IPC: H04R3/12
Filed: 1986-08-18
Granted: 1987-09-03
Abstract: The invention relates to a monitoring device for locating a loudspeaker failure for an installation comprising a number of loudspeakers (3) which are in each case allocated a fault detector (10) and a test circuit (11). A central unit (1) signalling the failure of a loudspeaker (3) in each case supplies to all test circuits (11) a differently coded digital serial test signal containing an address. A test circuit (11) only supplies a response signal to the central unit (1) when the address contained in the test signal corresponds to the address of the test circuit (11) and when the fault detector (10) has not found any fault. The fault detector (10) contains a function detector (14) for testing the operability of the loudspeaker coil and a pilot signal detector (13) for detecting an interruption or a short circuit in the loudspeaker transmission link (2) to which a pilot signal is applied. <IMAGE>

Title: Circuit arrangement for an ultrasound test set
Inventor: LATHER DIETER DIPL-ING
IPC: B06B1/02
Filed: 1986-11-15
Granted: 1987-09-17
Abstract: The transmitting and receiving coil in an ultrasound test set emits a relatively low power in the receiving mode so that it must be arranged as close as possible to the test object. The cable to the receiver must also be kept as short as possible for this reason. In order to increase the received power, the coil is divided into individual branches which run parallel to one another, a capacitor being connected in each case from one end of one branch to the other end of the adjacent branch. The ends of the branches are in each case connected to the transmitter, via a threshold circuit. The receiver is connected on the one hand to one end of the first branch and on the other via a capacitor to the other end of the last branch. In the transmitting mode, a parallel tuned circuit is produced in this way while a series tuned circuit is produced in the reception mode, whose tuned circuit elements each consist of a capacitor and a coiled branch. <IMAGE>

Abstract: FIELD: active coal production. SUBSTANCE: method, that includes mixing of carbon-bearing raw material with wood-tar binder and following granulation of mixture, provides for preliminary estimation of wood-tar binder and carbon-bearing raw material reaction capability for hardening duration in interval of 1 - 5 hours under room temperature. For the purpose they take the mixture in masses ratio of 1 : 1 after preliminary its holding for half an hour under temperature of t = 90 C. In case the mixture has not hardened within that time interval, then they increase reaction capability of binder. In case it has hardened for less than an hour, then they decrease reaction capability of carbon-bearing raw material. In the case reaction capability of binder is being increased using its oxidation by air under temperature of t = 110 - 125 C and they decrease reaction capability of carbon-bearing raw material by holding it in thin layer in the open air under room temperature.
