Title: Allocating automatic re-dial number storage space to subscriber - using unused holding time criterion when all storage places are occupied
Inventor: KOSSAKOWSKI MAXIMILIAN DIPL IN
IPC: H04M3/424
Filed: 1980-04-25
Abstract: The telephone exchange has compartmentalized data storage facilities allotted to groups of subscribers for optional use additional to the usual command and address storage units and the speech channel couple field, and provides the possibility for a part of the subscriber stations-responsive to a first demand signal - to be allotted a digital storage facility for automatically re-dialling the number of a called party. If such a first demand signal is used, and if the called subscriber answers, there is no need for any re-dialling, yet the allotted storage space remains associated with the calling station. Therefore, all subsequent numbers called are also temporarily stored, replacing the earlier ones. If any called party is engaged the calling party, to obtain automatic re-dialling, enters a second demand signal. Any station holding a storage location without having had to use it may lose it when all the storage places are occupied and at least one further request for the re-dialling storage facility is being made by a member of the subscriber group concerned. In that case, the storage space of that subscriber who has held it longest is taken from him and transferred to the newly demanding station.

Title: Electroless nickel plating of magnesium (alloy) - after pickling in acid mixt. pref. of nitric and hydrofluoric acids
Inventor: REISER HANS-DIETER
IPC: C23C18/18
Filed: 1980-06-14
Abstract: Magnesium (alloy) components, esp. pressure die castings, are pickled in an acid mixt. and then electrolessly nickel plated. Pref. the acid mixt. comprises 5-100 ml of 65% nitric acid and 5-100 ml of 40% hydrofluoric acid, per l of water and the electroless nickel plating soln. contains 2-10 ml of 40% hydrofluoric acid per l of water. The acid pickle produces a clean active surface, with little removal of magnesium or alloying elements, so that the nickel plating is adherent, and does not cause rapid deterioration of the nickel plating bath. Additionally, the process allows inserts, e.g. of steel or brass, in magnesium castings to be nickel plated simultaneously, without attack during pickling.

Title: Patterned fabric using single weft yarn - comprising two ends of different appearance wrapping alternately around each other
Inventor: KEMPF GERHARD
IPC: D03D15/00
Filed: 1980-08-22
Abstract: Patterned fabric is woven using a fancy weft comprising at least two yarns of differing optical appearance which are wrapped alternately around each other, one serving as a core yarn whilst the other becomes the covering yarn. The lengths of weft showing each type of yarn on the surface may be equal, and considerably longer than the fabric width, to give a weft-striped pattern in the woven piece, or the surface yarns may interchange at least once in each pick length to produce a pattern in the warp direction or at an inclined angle. This enables patterned fabric to be produced using a single weft yarn, obviating the need for stocks of different yarn types and for multiple-box looms.

Title: Method for determining the output and processing rate of vessel-storing processing machines
Inventor: BARGELE NORBERT DR
IPC: B08B9/20
Filed: 1981-05-23
Abstract: The invention relates to a method for determining the output and rate of treatment of containers in vessel-storing treatment machines, such as bottle-cleaning machines, pasteurising machines and the like, in which a multiplicity of bottles are simultaneously fed in alongside to one another and treated in a plurality of rows. In the case of such machines, the number of bottles fed in does not necessarily correspond to the number of bottles discharged at the same time; furthermore, the number of bottles delivered is not necessarily the number of bottles which can be determined from the set throughput. Special measures must be taken to compensate for such malfunctions and characteristics, especially when the throughput of such machines is an important determinant of the way in which overall systems are controlled. These disadvantages are remedied according to the invention in that the output is continuously calculated from the number of vessels fed in, the treatment time, the throughput and the current filling level of the machine, and the characteristic value resulting from this is used to control the output of the treatment machine itself and/or further machines assigned to it.

Title: Funnel-shaped front for vehicles of all kinds in conjunction with jet pumps as means of propulsion
Inventor: ROHLFING MICHAEL
IPC: B63H11/02
Filed: 1981-09-07
Abstract: A drive for vehicles of all kinds (ships, aircraft, automobiles) by means of jet pumps is proposed. Energy savings are achieved. The dashing of waves in the case of ships is reduced. The supersonic bang in aircraft can be avoided. The principle of displacement is eliminated. The object is achieved in that the front of the vehicle is designed in a funnel shape which extends open towards the rear of the vehicle, and in that a jet pump (internal combustion jet pump, steam jet pump, water jet pump or jet pump of some other design depending on the type of vehicle) is used, in the case of forward travel of the vehicle through the medium (for example water or air), to collect medium flowing into the funnel, suck it away to the rear of the vehicle (or pump it away) and eject it into the same respective medium as in the funnel.
