Title: Automatic attenuator for HF receiver resonant cct - has regulated attenuating transistor between tuning varactor input and supply pole
Inventor: KLANK OTTO
IPC: H03G3/30
Filed: 1973-07-16
Abstract: The automatic attenuator for a HF receiver resonant circuit enables varactor diodes to be used in AM receivers by employing a transistor as variable attenuator. The transistor collector is coupled to the junction between a varactor diode and the input transformer secondary, its collector is coupled to the supply, and its base to the control voltage output of the HF amplifier. The control voltage is proportional to the input signal amplitude, and accordingly regulates the transistor attenuation of the input signal. The transistor emitter and collector are capacitively coupled to its base and to earth so that HF signals appearing on the transistor are short circuited.

Title: Particles separated from centrifuged fluid stream - with central rotation speed reduced to reduce loss of head
Inventor: SCHMITZ HUGO
IPC: B01D45/12
Filed: 1973-08-03
Abstract: A method of separating particles from a fluid by centrifuging in a stationary chamber with tangential inlet and central outlet is carried out with regulation of the angular rotational speed of the "core" of fluid at the centre; this central core is made to revolve at constant speed (not increasing towards the centre), the general conditions being such that the particles have left the fluid before the fluid reaches the core. The fluid leaves the core region without any appreciable rotational motion. This gives reduced energy loss in the purified fluid at the outlet and further downstream.

Title: Guided torpedo launched from submarine - uses bathythermographic guidance for preventing discovery and improving hit probability
Inventor: TEWES HEINZ DIPL ING
IPC: F41G7/32
Filed: 1973-09-21
Abstract: The torpedo launched from a submarine is continuously guided for improving the hit probability. The torpedo guiding arrangement also greatly improves the chances that the launching submarine and the torpedo itself cannot be readily located. The torpedo trajectory is influenced in the launching phase by the existing bathythermographic conditions. The torpedo is held in the initial launching phase on a trajectory in which the noise propagation anomalies have a minimum range and thus prevent early discovery. This torpedo can alternatively be held in the launching phase on the trajectory in which one part of trajectory ensures minimum opportunities for discovery or in the other part of the trajectory to ensure maximum target sensing range. The torpedo during the minimum discovery range has a high velocity and the torpedo runs at low speed during the maximum target sensing part of trajectory.

Title: Signal content scrambling method - signal limited bandwidth is split into partial bands
Inventor: BITZER WOLFGANG DIPL ING
IPC: H04K1/04
Filed: 1973-11-30
Abstract: The voltage pattern of each partial band is in time intervals of specified length stored in one of the n stores, whose contents are subsequently consecutively read out at a speed increased by a factor equal to the ratio of the full frequency bandwidth to the width of the respective partial band, and transmitted. Signals received in the specified length time intervals are stored in n stores and simultaneously read out at a lower speed and contents of each store converted into the original partial bands, which are recombined into the original frequency band. The contents of the n stores are read out in irregular sequences controlled by a pseudorandom signal train.
Patent DE-2359916-A1 (DE)
Title: Coin sorter feed control - coin piling cases storage with switch inside the wall of centrifugal cup
Inventor: GROSS ERWIN
IPC: G07D9/00
Filed: 1973-12-01
Abstract: The spinning disc of the centrifugal cup carries the coins which are thrown against the inner wall by the centrifugal force. This contributes to the single-file feeding of coins by discharge channel comprising a counting station. The contact insulated from the wall of the cup is connected to an amplifier while the cup is earthed, the position of the contact precluding its sensing of the first layer of coins on disc. However, piling up of coins ensures that the contact is connected to ground via the lower layer of coins and the signal fed to the amplifier is then transmitted to a delay line allowing tripping only after a certain number of repeat pulses from contact.
