Inventor: GIBSON JOHN-PHILIP DR
IPC: H02P25/06
Filed: 1979-08-13
Abstract: Der Stator eines linearen Langstatormotors ist in Form einer ein Wanderfeld erzeugenden Drehstromwicklung entlang der Trasse verlegt. Die Drehstromwicklung ist in Streckenabschnitte mit jeweils mehreren Wicklungen unterteilt, die ueber Schalteinrichtungen abwechselnd an eines von zwei parallelen Streckenkabeln angeschlossen sind. Jedes Streckenkabel wird von ortsfesten steuerbaren statischen Umrichtern gespeist, die an seinen beiden Enden angeschlossen sind. Bei einer laengeren Strecke ist jeder Umrichter jeweils ueber eine Umschalteinrichtung mit den Streckenkabeln benachbarter Streckenabschnitte verbunden. Bei der erfindungsgemaessen Anordnung wird die Stromstaerke im Streckenkabel um etwa die Haelfte reduziert. Die Reduzierung der Stroeme auf den Streckenkabeln ermoeglicht es, den Querschnitt der Streckenkabel zu verkleinern. Die installierte Leistung der Umrichter kann infolge des reduzierten Spannungsabfalles am Streckenkabel verkleinert werden bzw. Es koennen die Streckenabschnitte verlaengert und es kann die Entfernung zwischen den Umrichtern vergroessert werden. Anwendungsgebiet: Magnetschwebebahn.                                                                                                                                                                                                                                                                                                                                                                              ...U.S.W

Title: Carbon adsorbents for selective adsorption of low molecular cpds. - from mixts. with high molecular substances
Inventor: SOLODOVNIK VALENTIN DMITRIEVIC
IPC: B01J20/32
Filed: 1979-11-19
Abstract: Carbon sorbents for selective adsorption of low molecular substances from mixts. of these with high molecular substances, are made by first immersing particles of active carbon in a liq. contg. no film-forming polymer, removing excess liq. from the particles, dispersing the particles in a soln. of a film-forming polymer in a solvent, sepg. the particles carrying a layer of the film-forming polymer from the soln., and drying the particles. Pref. the particles are presoaked in a liq. which has limited miscibility with the solvent used in the film-forming polymer soln. Specific examples of such systems are the use of CHCl3 as the liq., and aq. PVA soln. as film former, and ethyl ether as liq. and aq. methylcellulose soln. as film-forming polymer. Alternatively the liq. used may be a solvent having unlimited miscibility with the solvent for the film-forming polymer. Examples of such systems are the use of water as the liq. and an acetone soln. of acetylcellulose as film-former, and the use of hexane as liq., with a cyclohexanone soln. of PVC as film-former. The process gives carbon sorbents of high activity in which the selectivity for the sorption of low molecular materials is not impaired by redn. of the porosity of the material by plugging with film forming polymer. Prods. are useful in chemical processes and in medical applications.

Title: Incoming call barring for directly controlled exchange - has cross line monitor of subscriber loops controlling relay changeover switch block disconnect and announcement connection
Inventor: VOIGT WOLFGANG
IPC: H04M3/436
Filed: 1980-03-26
Abstract: The circuitry is for enabling subscribers on a directly controlled, ie step-by-step, telephone exchange to dial a number into that exchange so that incoming calls are barred to their own telephone for a period of time as required by the subscriber. The facility avoids the subscriber taking the phone 'off hook' or dialling an incomplete number and thereby holding equipment in the exchange which could be earning revenue carrying other calls. Each subscriber is provided with ancillary equipment(Z) which monitors (SU) the conditions on the speech wires(a,b,) of the subscriber's loop(TAL). When a specific dialled code, eg the subscribers own number, is received signifying requirement of the 'incoming calls barred' facility it is recognised by the monitor control circuit(AW) which has a stored record(SP) of the code number. The control(AW) energises relays(X,U) which switch the output from the exchange switchblock(LW)(X1,X2,X3) to a recorded announcement (AE), for the information of incoming callers, and disconnects the subscriber's loop from the input of the exchange switchblock(AS)(at U1). The subs handset can be replaced on the telephone. The monitor(SU) stays across the line ready for restoration of normal service.

Title: Wind-driven current generator - is coupled to vehicle electric drive and has rotary cylinder driving enclosed electric motors via cog transmission
Inventor: JUNKERS CLAUS
IPC: F03D3/02
Filed: 1980-11-24
Abstract: The generator comprises a sheet metal cylinder, with stamped out or attached vanes, supported via roller bearings from a rotary axis provided by a steel pipe. From one to four motors are arranged around this axis, with their drive cogs engaging a cog ring fitted around the inside of the cylinder, so that the motors are driven by the rotation of the cylinder due to the wind motion or the air stream when the current generator is attached to a moving object. The conversion ratio of the cog transmission is dependent on the rating of the motors with the current cables for the latter passed through the centre of the steel pipe. The generator can be used for an electric vehicle drive.
Patent DE-3100595-A1 (DE)
Title: Device for continuous levelling of machines, telescopes, workpieces, containers and other objects
Inventor: WEICHBRODT HERBERT E
IPC: F16M7/00
Filed: 1981-01-10
Abstract: The invention relates to a mechanical device for levelling heavy objects which are intended to be moved into a specific orientation or to a specific level (also called the "aligning element" in general technical language). The device consists of three parts which are easy to manufacture and whose essential function makes them generally usable as an aligning element or lifting element, as a result of the use of the differential thread. A base body (1), which is provided with a groove to prevent the actuating body (3) rotating, has a thread whose pitch differs from that of the actuating body (3). The actuating nut (2) engages in this thread, which actuating nut (2) engages by means of a further internal thread in the actuating body (3), in the same pitch sense. By rotating the actuating nut, this moves by one pitch of the thread on the base body (1) per revolution, but is screwed into the actuating body by the difference between the pitches of the two threads. Said actuating body is prevented from rotating at the same time by the arrangement of the pin/groove and can in consequence carry out only a lifting movement in proportion to the difference between the threads of the base body (1) and actuating body (3). A fine thread having a difference between the two pitches of 0.5 mm thus results, for example, from the coarse initial thread pairing of M36/M30. <IMAGE>

Title: Method for the absorption and final purification of pollutant-containing exhaust gases
Inventor: BAAR ERICH DIPL ING
IPC: B01D53/68
Filed: 1981-02-11
Abstract: The invention relates to a method for the absorption and final purification of pollutant-containing exhaust gases, in accordance with Patent Application P 2940099.5, which also contain, apart from easily absorbable gaseous pollutants, those, primarily dusty impurities which have a tendency towards encrustations and solid deposits in absorption devices. The aim of the invention is, by means of an effective and continuous absorption system, to shift the emission value of such pollutant-containing industrial exhaust gases to the permitted values which are frequently less than 5 mg/m<3>. This object has been achieved in principle in such a way that upstream of the final purification stage, in accordance with Patent Application P 2940099.5, which operates by the pure counter-current principle without forced liquid circulation, is connected a prepurification stage which operates with a liquid circulation. Preliminary and final purification of the pollutant-containing exhaust gases are carried out using throughflow sieve trays. The aperture cross-sectional areas of the throughflow sieve trays perforated with large holes are, in the prepurification stage, over 60% of the total cross-sectional area, as a result of which, in addition to the absorption effect, a very good scrubbing and self-cleaning effect is achieved and no stable liquid layers form over these trays.
