Title: Sea water desalination - with fresh water recovery for irrigation purposes
Inventor: BALDUS OTTMAR GUENTER
IPC: C02F1/14
Filed: 1977-11-30
Abstract: A system of irrigating agricultural areas with desalinated seawater uses buried pipes which extend from a seawater reservoir to a crystallisation basin. Hot ambient air is drawn into a vertical shaft of concentric plastic foil tubes, suspended from a balloon, enriched with moisture by a water spray and passed in the pipes to the crystallisation basin. Water vapour condenses on the outside of the porous tubes and irrigates the soil. This produces salt by crystallisation in open basin but does not waste the evaporated water. It is used for soil irrigation instead.

Inventor: NEUMANN WILHELM PAUL PROF DIPL
IPC: C07F7/22
Filed: 1978-07-10
Abstract: Distannane derivs. of formula (R1R2R3Sn)-2 (I) (where R1, R2 and R3 are very bulky aromatic and/or aliphatic gps. having a steric requirement on average greater than that of phenyl or neophyl gps.) are novel. The cpds. undergo purely thermal and reversible Sn-Sn bond cleavage at not >200 degrees C to form stannyl radicals, but irreversible decomposition is suppressed. (I) are useful as one-component initiators, stoppers and regulators for free-radical reactions. (I) are quite stable below their decompsn. temp. so can be mixed with reactants (e.g. polymersible olefins) and stored or transported. They decompose at a specific temp., dependent on nature of R1-R3, and unlike known radical catalysts are not explosive and do not produce several types of radicals, CO2 by-prod. etc. They react with alkyl- or aryl-halides to give very energetic alkyl or aryl radicals.

Title: Hearing aid with directional properties - relies on combination of electrical filtration and acoustic processing by using directional effect of higher frequencies
Inventor: RENATUS GUSTAV DIPL ING
IPC: H04R1/34
Filed: 1978-10-31
Abstract: In a conventional hearing aid, the microphone has wide-angle sensitivity, an undesirable feature when attention is to be given to particular speech against conversation noise coming from many directions. Frequencies below 1500 Hz are dispensible for speech intelligibility and accordingly the aid eliminates frequencies between 30 to 1500 Hz which have poor directionality by electrical filters in the amplifier system; on the other hand, acoustic impedances and delay lines passing frequencies between 1800 Hz and 5000 Hz to the microphone are provided. These have directional characteristics. In one embodiment the device is integrated with a spectacle frame (B) having lenses (G) and mounted on it a microphone (M) exposed to sound waves coming in front at (OV) and from the back through ducts (L) and orifices (OR) turned towards a source. The annex duct (marked D), serves to increase the effective propagation delay in the ducts (L). The arrangement can be chosen to provide for the frequency range contributing most to intelligibility a phase shift of 180 deg. thus reinforcing microphone action by 6 decibels directionally.

Title: Back-up disc storage for telephone exchange - has general and individual programmes stored on disc with complete transfer to working stores possible for maintenance removal
Inventor: WEHREND KLAUS
IPC: H04Q3/545
Filed: 1979-04-04
Abstract: The method is for operating a stored programme common control exchange with working stores having a back up disc storage system. One disc store is for the exchange operating procedures and system fixed data, and the second disc storage is for the network management operating protocol information which is alterable according to requirements. The method is also appropriate to PABX type installations. If the first disc storage unit (D1) is to be removed, e.g. by maintenance personnel, all its information is first transferred to a free place in an active store (SP) by the staff removing it. System application to the disc containing storage unit (HSP) is then blocked and the second disc store (D2) provides the programme facility to refer to the temporary working store (SP). The first disc (D1) may be removed from circuit for programme update and, whilst removed, a mark condition on the working store (SP) enables it for receipt of commands. When the disc (D1) is restored to service, the mark condition is removed. The system enables the disc stores to be removed from service without having to disable or limit the exchange facilities.
