Patent DE-3213084-A1 (DE)
Title: Device for recovering fresh water from sea water
Inventor: WAGNER HERBERT HANS
IPC: C02F1/14
Filed: 1982-04-07
Abstract: In the device according to the invention, the sea water is heated, pumped into a flash evaporator and then sprayed onto a heater in a vapour chamber. This heater produces a thermal circulating flow within the vapour chamber. As a result of this flow, volatile fractions are carried upwards, leave the upper part of the vapour chamber through slots and pass into a condenser where they condense as fresh water. Using the vapour chamber furnished with heaters, stable conditions can be maintained even when, for reasons of economy, the sea water is heated with solar energy and thus cannot be uniformly heated.

Patent DE-3308984-A1 (DE)
Title: Circuit arrangement for a digital telephone station
Inventor: PETRY SIGMAR DIPL ING
IPC: H04M1/68
Filed: 1983-03-14
Abstract: The invention relates to a circuit arrangement for a digital, transparent telephone station, where, for example, the feed voltage for the microphone amplifier is connected to the telephone station only by a code of the telephone system, and this code is triggered only by a preceding code from the telephone station to the telephone system (for example, signalling that the handset has gone off-hook). If the code is inadvertently or maliciously transmitted from the telephone system to the telephone station, this results in unauthorised activation of the microphone amplifier. This is intended to be prevented by the inventive idea. This is achieved in a simple fashion by inserting a contact in the microphone amplifier feed circuit which does not close until the handset actually goes off-hook.

Patent DE-3322869-A1 (DE)
Title: Sleeve anchor
Inventor: PHILIPP MARTIN
IPC: E04G21/14
Filed: 1983-06-24
Abstract: The invention relates to a sleeve anchor, in particular for anchoring in precast concrete parts. As a rule, a sleeve anchor of this type has an open region with an internal thread and a, normally, lower region, the latter being pressed with a fastening means. Since, with known sleeve anchors, especially when used in thin-walled precast concrete parts, ruptures of the concrete repeatedly occured in the region of the sleeve owing to transverse loads, the invention provides a possible solution to this. Provision is therefore made for the sleeve anchor according to the invention to be rigidly connected to at least two fastening means, these fastening means being bent up so that together they substantially completely enclose the upper region of the sleeve and protrude with their free ends substantially perpendicularly from the sleeve. The sleeve anchor is preferably formed and prefabricated in one plane with respect to the fastening means.
