Abstract: 1. Address-free fault locating method for transmission links for digital, in particular PCM signals, comprising intermediate stations which contain amplifying regenerators for at least two signal paths, by the transmission of a preparation signal which is transmitted to all the regenerators in the first signal path from a locating end station, a loop closure command, and a test signal, where the signal which is transmitted via the loop, formed between the regenerators of two signal paths of an intermediate station, to an analysing end station is checked in respect of bit errors and signal transit time, and where a sequence of a plurality of directly consecutive digital zero symbols, which exceeds the minimum non-occurring zero sequence in each block in the transmission code by a whole numbered multiple, is transmitted by way of loop closure command, with a transmitting-end series circuit comprising a locating signal transmitter (OG), a scrambler (Scr), and a switchable alphabet code converter (Acod) which converts blocks comprising m input symbols into blocks comprising n output symbols, and with a receiving-end series circuit comprising an alphabet code reconverter (Adec) and a descrambler (DScr) for the reconversion of the received signal, characterised in that at the transmitting end a locating pulse pattern is produced which is formed by a periodic sequence of words comprising eight digital zero symbols and four digital one symbols, that the produced locating pulse pattern is scrambled by means of a self-synchronising scrambler (Scr) known per se, in such manner that the scrambled locating pulse pattern contains at periodic intervals, a sequence of fifteen consecutive digital zero symbols, that this signal is fed to the switchable alphabet code converter (Acod) which, on the occurrence of the fifteen consecutive digital zero symbols, emits a whole number of blocks comprising n zero symbols, that here the output-end number of blocks comprising n zero symbols does not exceed the value 15/m, that the blocks comprising n zero symbols are emitted as loop closure command to the transmission link, that the self-synchronising scrambler (Scr) includes a total of seven stages and emits a signal having a period of 2**7 -1 bit und that the period of the scrambled locating pulse pattern has a length of 1524 bits.

Abstract: Casing inspection apparatus and method are disclosed for determining defects and other anomalies in ferromagnetic oil well casing. The inspection apparatus utilizes a pair of coaxial transmitter coils for generating an alternating magnetic field in the casing thereby inducing circumferential currents in the casing wall. These circumferential currents and the magnetic field associated with the currents are perturbed by corrosion, holes, and other anomalies both inside and outside the casing wall. Differential receiver coils are urged in proximity with the casing wall to generate a differential receiver signal in response to such perturbations in the magnetic field. The differential receivers are provided with three coils serially connected and having N, 2N and N winding turns respectively. The windings of the coils are disposed in adjacent relationship to one another and wound in a direction opposite to the adjacent winding. The casing inspection apparatus achieves enhanced sensitivity to small defects and reduced sensitivity to magnetic anomalies by processing both the amplitude and phase components of the receiver signal.

Abstract: In order to make ergosine available for wide pharmaceutical use there is a need for Claviceps strains which are capable of saprophytic production of ergosine which is virtually free of additional alkaloids, and which are distinguished by stability, high alkaloid production and good fermentation properties. This is achieved by using for the preparation of ergosine the strain Claviceps purpurea (Fr.) Tul. IBP 179, its mutants or variants. The strain produces a total alkaloid mixture (about 900-1300  mu g/ml of nutrient medium) of which at least 50% of the alkaloids can be extracted with organic solvents (about 80-90% ergosine/ergosinine and 10-20% easily removable substances). The strain is cultivated by aerobic fermentation in a liquid nutrient medium which contains an assimilable carbon source, an assimilable nitrogen source and mineral salts, in a surface and/or submerged culture at a temperature of 20-30 DEG C and a pH of 4.0-6.2 for a period of 7-35 days. 95% of the produced alkaloids are released into the nutrient medium, from which ergosine/ergosinine is isolated.

Title: Discontinuous emulsion polymerisation process of vinyl chloride
Inventor: PYRLIK MANFRED DR
IPC: C08F259/04
Filed: 1980-09-04
Abstract: A process for the discontinuous emulsion polymerisation of vinyl chloride or monomers which can be copolymerised therewith essentially comprises carrying out the polymerisation in the presence of two seed latexes of different particle sizes and different proportions by weight, based on the monomers used, which have been prepared in emulsion. The first seed latex should have particles having a mean diameter in the range from 0.12 to 0.6  mu m and should be present in a proportion of from 0.5 to 5% by weight based on the monomer. The other seed latex should have a mean particle diameter in the range from 0.02 to 0.08  mu m and should be present in a proportion of 0.05 to 0.5% by weight, based on the monomer. The process according to the invention allows the emulsion preparation of PVC latexes which can be processed by spray drying to give PVC pastes. The invention facilitates the preparation of low-viscosity pastes at high shear gradients.

Abstract: This disclosure relates to an improvement in the strength of a bottle bottom of the champagne type by the addition of ribs (75) internally of the preform (44) when the preform is axially stretched prior to the blowing thereof within the blow mold. Most particularly, by adding internal ribs (75) to the interior surface of the bottom defining portion (49) of the preform (44), the preform has the bottom forming portion unduly strengthened against shrinkage in wall thickness when the preform is axially lengthened through the use of a stretch rod. The net result is that the stretching of the preform (44) and the thinning of the wall is held to a minimum in the bottom forming portion (49) of the preform and is transferred primarily to the body forming (78) of the preform where lesser wall thickness does not unduly detract from the strength of the bottle.
