Title: Radioisotope stimulated relay equipment - with closed loop interlocking feed back
Inventor: POSDNIKOW WLADIMIR NIKOLAJEWIT
IPC: G01T7/12
Filed: 1972-08-14
Abstract: Ionizing radiation from the radioisotope source (1) falls on a detector (2) which converts the energy into electrical pulses fed to one input of a discrete comparator stage (4) within the electronic relay unit (3). The relay stage (5) following the comparator has its outputs (A) also looped back to a threshold frequency "gauging" stage (6) whose output feeds the second input of the comparator (4). The output pulses from the detector are statistically distributed and the "gauging" stage (6) produces a regular pulse train distinguished by two discrete threshold values switched according to the final output state (A) so that the YES-NO condition of that final output is dependent on the ratio of the frequencies, to be compared, of the statistical and regular pulse trains. Sensitivity, quick response, non-ambiguity.

Title: Homogenisation of briquetting mixt. - by steam injection heating of coal dust and agglutinant turned into froth
Inventor: SZIGETVARI JOZSEF
IPC: C10C1/14
Filed: 1973-08-17
Abstract: A mixture of coal dust and bitumen or pitch is homogenised by heating the coal dust prior to briquetting to a temperature which exceeds the softening temperature of the bitumen or pitch by 5-20 degrees C, (a temperature of 90-95 degrees C). This material is mixed with bitumen or pitch which has been heated to a temperature 80-130 degrees C above its softening temperature to produce an agglutinant froth. This froth is mixed with the material to be briquetted. This system results in a lower consumption of agglutinant. Coal with a high moisture content need not be dried, thus saving energy. The lower agglutinant content results in a better briquette quality.

Title: Tetrahydro-thiophene prepn. - by heating tetrahydro-furan with sulphur or phosphorus sulphides
Inventor: CHAJRULLIN WASICH KASCHAPOWITS
IPC: C07D333/08
Filed: 1973-11-28
Abstract: Tetrahydro-thiophene is prepd. by heating tetrahydrofuran with stoichiometric proportion of sulphur or phosphorus sulphide at 175-215 degrees C and subsequently isolating the product. In a pref. procedure, the tetrahydrofuran is reacted with sulphur in the presence of 0.5-1 gramme-atom of red phosphorus psn. mol. tetrahydrofuran, pref. at 180-200 degrees C. Tetrahydrothiophene is used as an intermediate for thiophene, tetramethylene sulphoxide, sulpholane and 1,4-dihalobutanes. These products, in turn, are used as fuel additives, for the extraction of aromatic hydrocarbons from mineral oil products, in the production of polysulphide elastomers, and in the medicinal and other industries. The simple process uses relatively low reaction temperature and non-toxic and non-explosive sulphidizing agents. The process can be carried out in steel vessels without risk of corrosion.

Title: Synchronisation method for counters - counters are in two independently synchronised groups
Inventor: KARL OTTO
IPC: H03K21/40
Filed: 1974-02-20
Abstract: Each counter group has a superordinate reference counter synchronised by a first reference counter synchronisation circuit with a group subordinate reference counter. When the two reference counters are synchronised, a synchronisation signal for this group counters synchronisation is applied to synchronisation circuits individually allocated to these counters. In order to synchronise reference counters in different groups, this signal is also applied to a second reference counter synchronisation circuits in the other groups. Should a counter become subject to interference or develop a fault at least half of the synchronized counters will remain functioning correctly. Both reference counter groups are equalised in their functions and are not rigidly coupled to each other.
