Title: Sewage sludge conversion into fertiliser - in multideck tower with bar grating passages in partitions and air circulation
Inventor: SCHREIBEN AUGUST DR ING
IPC: A01C3/02
Filed: 1974-05-29
Abstract: Sludge from sewage plants and/or refuse is converted into fertiliser in a cylindrical vertical tank which is subdivided by partitions into several chambers. The passages in the partitions terminate downwards in bar gratings which act as spacers to maintain a cavity for the introduction and extraction of air. Stirring arms are fixed to a central vertical shaft to mix and agitate the compost. This system eliminates the need for flap valves and for large unutilised container volumes. The baking or clinkering of sludge and refuse is prevented and an adequate aeration is ensured for the whole throughput. The passage height can be greater without detrimentally increasing the compressive load on the bottom layers.

Title: Constant current supply with output and polarity selection - using transistor constant current generators and logic inputs
Inventor: WINTZER KLAUS
IPC: G05F1/56
Filed: 1975-02-28
Abstract: The network provides a number of constant current outputs, which may be selected by logic input signals and which may be of either polarity according to an input signal. The network consists of a number of almost independent circuits each of which constitutes a constant current generator with a double transistor output, the polarity being determined by which of these transistors is conducting. The transistors (T1n, T2n) are of opposite types and are connected via their collectors to the relevant output (In). A current generating circuit, consisting of a linear amplifier comparator (V1n, V2n) and an emitter resistance (R1n, R2n), provides constant current from the appropriate collector if it is selected. The selection is by means of logic gates (GUn, GSn), the inputs to which are provided by a single flip-flop (5) for the whole network, and by individual selection signals.

Title: Fail safe transmission of on off data - using square wave quiescent signal typically for railway signal systems
Inventor: GO GIOK BIE DIPL ING
IPC: G08B1/08
Filed: 1975-07-16
Abstract: A fail-safe method of transmitting simple on-off data for railway signal driving application and the like where security of signal and of system operation is of the highest importance, is presented. Signals are normally driven over a transmission line pair via a relay contact (3) from a rigid regenerator (2) so that the relay contact is closed in the quiescent state. If a short circuit occurs along the line, the quiescent state is not disturbed, but the active signal will fail. The present arrangement superimposes a square wave (7') on the quiescent signal by means of a signal generator (9) so that any short circuit on the line can be detected at the receiving end. The usual relay is replaced by a light sensitive diode and transistor drive pair (3').
Patent DE-2532944-A1 (DE)
IPC: H04Q3/62
Filed: 1975-07-23
Abstract: In this switching signal system with primary and secondary signals (HK, NK) for connection traffic between primary and secondary systems, a signal corresponding to the cleardown signal is transmitted to the calling system (HA) before the transmission of the reply signal (M) if an unauthorised station of the distant system (WUA) is dialled up and thus cleardown of the devices involved in the connection, release of the connection line and also, in the system (HA) regarded as the calling system, signalling of the dial-up of an unauthorised station are controlled. AC and audio-frequency signals are used for this purpose. It is thus possible to identify in simple fashion in the calling system that the cleardown of the connection involved a cleardown due to dial-up of an unauthorised telephone station in the distant system. <IMAGE>
