Patent DE-3603605-A1 (DE)
Title: Process for treating water in the aquifer to decrease the nitrate content
Inventor: ELMER STEFAN
IPC: C02F3/30
Filed: 1986-02-06
Abstract: To decrease the content of nitrate and/or other undesirable nitrogen compounds in water delivered from the groundwater of an aquifer, a process is proposed in which the ratio of total hardness to carbonate hardness is modified underground by injection of suitable compositions in the aquifer, in the case of water having a carbonate hardness below about 4 DEG  dH, the carbonate hardness is increased by injection of a water enriched with carbon dioxide or a carbonate or bicarbonate and, in the case of a water having a carbonate hardness above about 4 DEG  dH, the total hardness is decreased by injection of a water containing an alkalising composition. In both cases, the ratio of total hardness to carbonate hardness is decreased and led towards one.

Title: Method for a computer-controlled private telephone branch exchange, particularly for a key system, with the possibility of inserting an attention signal in the busy case
Inventor: THELIGMANN WOLFGANG
IPC: H04M9/00
Filed: 1987-07-10
Abstract: Those telephone sets (TO...Tn) which, in addition to the digit keys, also exhibit a plurality of function and/or name keys, and normal telephone sets (Tm...Tx), can be connected as terminals which are to be connected to the private telephone branch exchange. The normal telephone sets are connected with two wires and are equipped with a single additional signal key apart from the digit input unit. If then a subscriber signals his own call request by inserting an attention signal into an existing call connection, this can be answered from an involved normal telephone set, which therefore does not exhibit any function keys which are allocated to particular performance features, in the simplest manner without special procedures. If the call connection is terminated by the subscriber station for which the inserted attention signal is intended, this combination leads to the control processor unit applying the ringing signal for this terminal concerned and switching through the connection when the subscriber answers. The required subscriber is thus automatically connected to the so-called waiting subscriber if the handset of the latter is still off hook or he has maintained a function which corresponds to this off-hook state. <IMAGE>
Patent DE-3723712-A1 (DE)
Title: Device having a plurality of electrical units, especially solenoid valves
Inventor: KLOCKE HARALD
IPC: H01F7/18
Filed: 1987-07-17
Abstract: A device is described having a plurality of solenoid valves for controlling fluids, in the case of which device an electronics unit is assigned to each solenoid valve. The solenoid valves can be permanently connected to the electrical power supply network and are called up and coded via a control line, which connects all the solenoid valves in a series circuit, for the purpose of setting up the circuit. In this case, only one solenoid valve is addressed in each case and is bridged after coding has been carried out, so that, on the one hand, such a solenoid valve is removed from the further coding process and, on the other hand, the next coding signal is fed to a next solenoid valve with an analogous effect. Once all the solenoid valves have been coded, a coded operating signal is admittedly recorded by all the electronics units but is converted only by that which is suitably coded into a circuit of the associated magnetic coil.
