Title: Arrangement for controlling converters
Inventor: GIRSCHIKOFSKY MANFREDF DIPL IN
IPC: H02M7/529
Filed: 1983-07-27
Abstract: The invention relates to an arrangement for controlling converters in multi-pulse bridge circuits, in which the turning-on and turning-off pulses are generated by control clocks and are supplied in a defined manner to the semiconductor valves. In order to achieve a high degree of standardisation in converter controllers, which applies to the logical locking of the turning-on and turning-off clocks, it being intended that the turning-off time, pulse nature of the switching and chain pulse be freely selectable or not, it is proposed according to the invention that the generation, logical distribution and mutual locking of the control pulses be combined in a passive, digital control network. Only the required input signals are supplied thereto, from a separate control-clock forming device. The said network can be used universally, irrespective of the type of turning-on and turning-off pulses required or desired for a converter type which is to be controlled, and contains a multi-phase state register (1) with a downstream-connected decoder (2), downstream of which pulse-forming stages, separated via logic elements, for turning on (3, 5) and turning off (4) are connected. <IMAGE>

Patent DE-3401931-A1 (DE)
Inventor: BESCHE ANTON
IPC: F16L11/08
Filed: 1984-01-20
Abstract: A flexible, very high pressure hose as a flexible conducting member in hydraulic systems. The wall of the hose contains filamentary load-carrying cords which are embedded in two or more layers. The load-carrying cords are combined to form a plurality of strips which cross one another or are braided with one another. The present invention deviates from the heretofore known symmetrical arrangement where the strips of a given layer have the same number of load-carrying cords in both directions, and instead provides an asymmetrical layer construction including strips which in one direction have a different number of load-carrying cords than do the strips which extend in the opposite direction. While the local resistance to pressure remains the same, the advantages of the present invention are distinct improvements, primarily in the flexibility and the service life of the novel hoses.

Title: Process for operating a two-stage gasifying burner
Inventor: KOSTKA HANA
IPC: F23C9/00
Filed: 1984-08-02
Abstract: The invention relates to a process for operating a two-stage gasifying burner at a total air index  lambda ges of at least approximately 1.0. According to the invention, in the first mixing chamber (2), an at least partially evaporated, liquid fuel (4) introduced at virtually no applied pressure is mixed with a combustion exhaust gas part-stream (6) which is about 8 to 35 % by weight of a combustion exhaust gas stream (26, 32), and with a preheated primary air (8) at an air index 0.03 </=  lambda 1 </= 0.05 and this fuel vapour/air/exhaust gas mixture is catalytically gasified in the subsequent catalyst device (12) to form fuel gas (14) which is then mixed with a combustion exhaust gas part-stream (18), which is about 10 to 25 % by volume of the combustion exhaust gas stream (32), and with a preheated secondary air (20) at least approximatley stoichiometrically and is then burnt in the combustion chamber (22). A continuously controllable, particularly low-pollution gasification burner is thus obtained, which can be operated with fuel liquid under standard conditions and is suitable as a heat source for a Stirling engine. Moreover, the gasification burner serving as the heat generator is intended with the aid of the process to be matched to the output of the Stirling engine in a continuous manner in the load range 1:8 and the efficiency of the system is intended to be increased. <IMAGE>

Title: Process for producing bitumen from underground deposits
Inventor: PACHOVSKY ROHAN ALEXANDER
IPC: E21B43/24
Filed: 1984-09-17
Abstract: Bitumen is produced from underground deposits of heavy oil sands by injecting air mixed with a heating fluid, in particular steam and/or hot water, and an alkalising agent into the deposit. The temperature of the deposit is thus raised to 93-177 DEG C and a part of the bitumen is thereby oxidised to form crude oil acids which, together with original crude oil acids, are neutralised to form emulsifiers. A bitumen/water emulsion is then recovered, which is separated above ground and from which the bitumen is produced. An enhanced efficiency of the process is obtained by means of a varying pressure load on the deposit.

Title: Process for producing a pipe-insulating connection
Inventor: KORECKY PAVEL DIPL ING
IPC: F16L25/02
Filed: 1985-09-03
Abstract: The invention relates to a process for producing a pipe-insulating connection, which comprises two machined pipe pieces inserted one into the other, between which at least one sealing ring of a flexible, electrically non-conductive material is inserted and the remaining spaces between the two pipe parts are filled with an electrically non-conductive sealing composition (for example epoxy resin), which after curing permanently ensures the deformation occurring due to compressing of this sealing ring. 
<??>The invention consists in that, after putting together the two pipe parts, first of all the two parts are pressed together in such a way that the required deformation of the sealing ring is achieved and then the spaces between the two parts are filled with a sealing composition. Filling with the sealing composition is preferably carried out under pressure. During the production process it is possible to measure the electrical resistance of the insulating connection and also the axial pressure, which also causes the required deformation of the sealing ring. 
<??>This pipe-insulating connection serves as effective corrosion protection of steel-pipe gas lines of any clear width, in particular against the effect of stray currents.

Title: Device for a voltage regulator
Inventor: HELLE WOLFGANG
IPC: G05F1/575
Filed: 1985-10-16
Abstract: A device for regulating a direct-current battery voltage within the range of about 3.5 V to 30 V for a load using direct voltage, in which the input of a voltage regulator is connected to the battery and its output is connected to the load, has the following features:   a) The emitter of a PNP transistor (V7) is connected to the input and its collector is connected to the output of the voltage regulator (V1). b) At the output of the voltage regulator (V1), one terminal of a threshold element (V4, R1) is connected which determines whether the output voltage (UA) has dropped below a certain nominal output voltage value. c) The threshold element (V4) controls the input of a bistable flip flop (V2) which has a switching hysteresis with a width of several volts. d) The output of the flip flop (V2) controls the base of the PNP transistor (V7) at least indirectly. This reduces the voltage drop across the voltage regulator to about 0.02 V and results in better utilisation of the battery capacity, particularly in portable devices and vehicles of significance. <IMAGE>

Title: Process for the preparation of pigmented and waterproofed fibre materials and fabrics
Inventor: MAIER HANS-PETER DR
IPC: D06P1/44
Filed: 1985-12-21
Abstract: Dyeing or printing with pigments and subsequent waterproofing of textile fabric webs for tarpaulins, awnings etc. was hitherto carried out in separate steps with intermediate drying and fixing after pigment dyeing, because in the case of wet-on-wet application of the waterproofing using a padder the unfixed dyeing runs, the continuity of the pigment binder is impaired as a result of the forcing in of the waterproofing and the cationic adjustment of the waterproofing agents when mixed with the anionic pigment binders can make the padding liquor unutilisable. According to the invention, a wet-on-wet application can be carried out with elimination of the intermediate drying and fixing without the disadvantages mentioned if the waterproofing liquor is applied in metered form and to a great extent without adverse squeeze effects to the predyed or printed textile fabric web, and then dried and fixed by dry heat.
