Patent HU-201960-B (HU)
Title: New process for producing 21-acetoxy-16alpha-ethyl-19-norpregna-4,6-diene-3,20-dione
Inventor: BAKOS TAMAS
IPC: C07J5/00
Filed: 1988-11-11
Abstract: Novel prepn. of 21-acetoxy-16alpha ethyl-19-nor-pregna-4,6 -diene-3-one involves the addn. of 2 mols. of hypobromous acid to the di:ethynyl gp. of 17alpha-ethynyl -19-nor-testosterone acetate. The glucimal di:bromo cpd. obtd. is reduced to the mono-bromo cpd. by tri:methyl-phosphite. A 16-unsatd.-21-acetoyx-pregnane deriv. is obtd. by cleaving off the 17-beta-acetoxy gp. with potassium-acetate and by the exchange of the bromo-acetoxy gp. The 4-unsatd.-3-ketone functional gp. of this deriv. is protected by its selective conversion to di:enol-ether 1,4 Grignard addn. reaction with ethyl-magnesium-bromide in the presence of a copper salt yields a 16alpha-ethyl deriv. The Z1-OH gp. lost through deacetylation is reacetylated and is followed by the development of delta6 double bond by chloromil. - Selective tritiation of the 21-acetoxy-16-alpha-ethyl 19-nor-pregna-4,6 -diene-3-one product leads to 3H-ORG-2058 cancer-diagnostic agent

Title: Spatial solar energy battery
Inventor: PUTĀNS Henriks
IPC: F24S23/77
Filed: 2011-10-03
Abstract: The offered spatial solar battery, which directly converts the solar radiation into electric energy, consists of individual flat and thin layer photo-electric modules. The modules are assembled and connected in the battery so that they form a truncated polyhedron, the intersectional plane of which forms the base, but the top oriented part makes the work surface of the battery. The special construction of the solar battery is needed to extend the possibilities of the use of the diffuse solar radiation energy. The polyhedron of the battery is composed of three isosceles trapezoidal shape photo-electric modules' groups of three different sizes. The modules of each size group are assembled upright in circles forming truncated pyramids. Then different size truncated pyramids are loaded on the top of each other. The dimensions of each group modules are chosen so that the length of upper parallel side of bottom group trapezium is equal with the upper length of trapezium bottom parallel sides. Each of modules' group is supplied with voltage transformer, and each of modules into the group is mutually connected using special electrically separating diode, in case its voltage is higher than others in the group.

Abstract: 1,014,523. Tunnel diode supply arrangements. RADIO CORPORATION OF AMERICA. April 2, 1963 [May 9, 1962], No. 13085/63. Heading H3T. A biasing circuit for a voltage controlled negative resistance diode comprises a non- linear resistor having a dynamic resistance which is lower than the absolute value of the minimum negative resistance of the diode at the operating voltage at which this minimum negative resistance occurs. As described an oscillator, Fig. 5, comprises a resonant transmission line 44, 46 connected to a tunnel diode 48. The non-liner resistor is a backward diode 50 placed in parallel with the tunnel diode at a voltage node on the line and connected to a bias supply 52 via a variable resistor 54. Referring to Fig. 1, the backward diode may be chosen to have a characteristic 36 which exhibits a lower resistance at the point 40 than the tunnel diode, thus producing a stable circuit as seen from the bias source. At greater values of E however the dynamic resistance of this diode is greater, thus reducing the power losses in the circuit.

Abstract: 1,135,309. Telegraphy. SIEMENS A.G. 2 June, 1967 [3 June, 1966], No. 25470/67. Heading H4P. A telegraph exchange includes a group of trunk-line circuits which are seized successively, and has means operative only after seizure of all the line circuits in the group for delaying the renewed seizure of any line circuit which has become free: the delay gives time for the connection to break down. When a subscriber calls, a central control unit ZSt connects itself to the subscriber and to a free line circuit of the group Uel-Uen, and the subscriber is connected to the selected line circuit. Suppose all the line circuits are free. Relays F1-Fn, FB, and FW are energized, their contacts being in the positions shown. ZSt gives a signal on TA when any line circuit is free. If a line circuit, e.g. Uel, is seized its relay F1 is de-energized, and cannot be energized again until fw reverses. This will not occur until all the line circuits Uel-Uen have been seized, whereat FB and FW drop so allowing FG to be energized via any line circuit now free and energizing the associated relay F. A timing unit ZTG provides pulses in cyclic succession on outputs GL1-GL4, pulses on any one output being spaced by sufficient time to allow a connection to breakdown. Suppose that prior to a pulse on GL2 all the line circuits had been seized and Uel had become free so that F1 was energized. When the pulse occurs on GL2 relay G2 is energized, so energizing GS. Contact gs2 prevents any line circuit which subsequently becomes free from energizing its relay F until GS drops. At the next pulse on GL2, relay FB is energized. Hence FW is energized and FG drops; fg2 opens and GS drops. Unit ZSt prevents any line circuit from being seized while FW is de-energized, i.e. during the break-down monitoring time.

Title: A circuit arrangement for a data telecommunications exchange
Inventor: FRANZ DIETMAR
IPC: H04L12/52
Filed: 1982-03-18
Abstract: A data exchange system is connected to at least one signal converter in which digital signals emitted from teletex subscriber stations are converted so that they may be processed by teletex subscriber stations, and vice-versa. In order that the load on the signal converters may be as low as possible in the event that digital signals cannot be deposited in the desired subscriber station, the data exchange system is additionally connected to at least two special teletex transmitting/receiving devices. These teletex transmitting/receiving devices can be operated by a special call signal only in the event that a teletex subscriber station or a signal converter is currently unable to deposit digital signals in the desired subscriber station. In response to such operation of the teletex transmitting/receiving devices, the latter is supplied with digital signals which cannot currently be deposited, together with additional information which enable the establishment of a connection to the desired subscriber station. Subsequently, the teletex transmitting/receiving device is able to transmit the digital signals which it has received, on the basis of the additional information, to the desired subscriber station.

Title: Vertically extending plate electrode for gas-forming electrolyzers

Abstract: In gas-forming electrolyzers, particularly membrane electrolyzers having vertically extending plate electrodes, each electrode plate is divided into horizontal strips and the entire active electrode surface is parallel to the counterelectrode and spaced from it as closely as possible. The top portions of each of the horizontal strips into which the electrode is divided define gas escape paths and extend away from the counterelectrode. To improve the degassing of the electrolyte the ratio of the distance G between the counterelectrode or membrane and the gas-defining line S at the lower edge of each electrode strip to the distance E between the counterelectrode or membrane and the breakaway edge K of the angled portion defining the gas escape path corresponds to a degassing capability F which is lower than 0.6.
