Title: Desulphurisation of fossil fuels, esp. petroleum residue - using alkali metal mono-sulphide hydrate in a process which regenerates the latter
IPC: C10G29/10
Filed: 1980-01-14
Abstract: Desulphurisation of petroleum residue comprises treatment with a reactive hydrate of an alkali metal monosulphide (I) at 120-325 degrees C to form alkali metal polysulphides (II). The improvement comprises (a) sepg. at the above temp. a mixt of unreacted (I), (II) and desulphurised residue; (b) hydrolysing (II) in a closed system, by adding >=1 mole of water per mole (II) to the mixt. thus forming steam and H2S; (c) sepg. the steam and H2S from the system thus reducing the water content to that of (I) and then sepg. the (II) having the highest S content from the (I); and (d) sepg. the hydrate of the polysulphide for recycling. The process is made more economical by allowing reagent to be recycled. The desulphurisation process is applicable to fossil fuels in general.

Title: Passive IR intruder detector using rows of mirrors - provides fields of view covering respective detection ranges by using series of differing focal lengths spherical mirrors
IPC: G08B13/193
Filed: 1982-01-05
Abstract: The detector includes a reflection unit with a row of mirrors extending along an optical axis and comprising a number of reflective spherical segments, each with a given focal distance and orientated to provide a respective field of view. A second row of similar mirrors along the same optical axis each have a given focal length and a common focus with the first row of mirrors. They provide further respective fields of view.

Title: Improvements in photosensitive relief image-forming materials
IPC: G03F1/00
Filed: 1982-03-23
Abstract: A relief image-forming composition having an acidic pH comprises a photosensitive component and an indicator capable of existing in two states differing in actinic opacity dependent upon pH. A relief image is formed by (1) exposing to light selected areas of a layer of the composition, the indicator being in its state of lower actinic opacity, (2) removing layer material from the exposed areas or from the unexposed areas and (3) shifting the pH in the remaining layer material to a value at which the indicator exists in its state of higher actinic opacity. The resultant image can then be used as an intermediate original in diazotype copying processes.

IPC: A44B19/16
Filed: 1986-11-04
Abstract: A reclosable extruded plastic fastener for joining sheet material such as walls of bags, and method of making the same.

Title: Method for forecasting earth tremors caused by the moon travel around the earth
Inventor: ILIEV BOJKO G
IPC: G01V1/00
Filed: 1997-02-11
Abstract: The method serves for the determination of the date of aforthcoming earthquake with a force larger than magnitude 2 to 3based on Richter's scale, but it is not possible to forecast itsmagnitude. It consists of simultaneous fixation of the data ofalready occured earth tremors on the same geographical place andthe position of the Moon on the equatorial co-ordinate system. Theregularities obtained are used for the indication of the date of aforthcoming earthquake considering the so-called cause and effectcircle on which a natural relation is detected among many tremorsoccuring in the same geographical place. This relation is shown inthe equality of the angle between the straight lines connectingthe date of past earthquakes. The indication of the most probabledate occurs by excluding the dates which are not in conformitywith the natural relations indicated in accordance with themethod.1 claim, 4 figures
