Title: Method of 1-omega-di (acetyl thio) alkane production
Inventor: DOLEZAL STANISLAV ING CSC
IPC: C07C315/06
Filed: 1987-12-22
Abstract: The solution concerns the new method of the production of 1, ω-di-(acetylthio)-alkanes of the general formula I<IMAGE>where n is 2 to 7, which is based upon the alkylation of potassium thiolacetate by 1, ω-dichloralkane of the general formula II<IMAGE>where n is 2 to 7 by heating in a suitable dissolvent e.g. in the low homologue of alcohol with 1 to 4 carbons in the molecule. Diacetylthioalkanes of the formula I, especially the homologue where n is 2, can be used as the starting substance for the synthesis of more complex sulphuric compounds as e.g. amino-acids containing sulphur and sulphury derivates used in photographic and pharmaceutical chemistry. 1, 2-di-(acetylthio) ethane can be used to generate 1, 2-ethandithiol in the appropriate reaction mixture because this acetyl derivate is crystallic and it has no undesirable mercaptan odour in the dry state during the normal treatment.

Title: Marine structure
IPC: B63B35/44
Filed: 1984-05-08
Abstract: A flexible structure of controlled yieldability for use as a hydrocarbon drilling and production platform in deep seas, or as a mooring point for oil tankers, constituted by a foundation base assembly, a vertical cylindrical tubular element placed under tension by a buoyancy chamber disposed at its top in proximity to the water surface, and an overlying lattice which at its top supports the plant platform. The tubular element is connected at its lower end to the base and at its upper end to the buoyancy chamber by means of suitable profiled tapered terminal elements able to withstand the bending loads which are generated at said connections. The entire structure is constituted by four separate pieces, namely the foundation base assembly with the lower terminal element, the lower half of the cylindrical tubular element, the upper half thereof, and the upper buoyancy chamber which is connected at one end to the upper terminal connection element and at the other end to the top lattice. For transportation purposes, these four pieces are assembled telescopically in pairs. On final on-site installation, the telescopic tubular parts are connected together and to the respective profiled terminal elements by mechanical clamps which restore complete structural continuity along the entire axis of the structure.

Abstract: 1439837 Increasing the conductivity of fibres; antistatic yarn DOW BADISCHE CO 13 July 1973 [14 July 1972 21 Sept 1972] 33424/73 Headings D1K, DIP and D1W The electrical resistance of a filament is reduced to not more than 10<9> ohms/cm by suffusing finely divided electrically conductive particles into the annular region at the periphery of the filament. The particles may be 20-40 millimicron carbon black, silver, aluminium or bronze. They occupy the region extending up to 0.1 r inwards from the periof circular cross-section and the radius of the largest circle which can be inscribed within the cross-sectional perimeter of trilobal square and rectangular filaments. The particles comprise 2-20% by wt. of the filaments and give it a resistance of 10<4> to 10<9> ohms/cm. The filament may be a polyamide polyester, polyolefin polystyrene, polyacrylic, modacrylic or cellulosic and have a denier of 1 to 100. The conductive particles are preferably applied as a dispersion in a solvent for the filament (aqueous formic or acetic acid for nylon 6, acetone for cellulose triacetate and for modacrylic (60% acrylonitrile, 25% vinylidine chloride and 14% Butyl acrylamide) and benzene for polystyrene. Nylon 6 may be dissolved in the formic acid or sulphuric acid dispersions to increase its viscosity before it is applied to the polymer. In the examples the filament is drawn between 2 polyester pads saturated with the dispersion and the solvent is vapourised by air jets or removed by washing the filament. The dispersion may also be applied by painting, spraying, dipping, rolling and printing. Pile fabric A nylon 6 15 denier monofilament was suffused with carbon black particles and then twisted with a bulked 2600 denier continuous filament nylon 6 yarn comprising 136 strands to form an antistatic yarn. A level loop carpet having a pile height of 0.6 cm was prepared using a jute backing and a tufting machine, every fourth yarn being the antistatic yarn, the remainder being the 136 strand yarn. The electrically conductive filament comprised 0.2% of the weight of the carpet.

Abstract: 1395723 Container carriers J H GAUNTLETT 29 Sept 1972 [1 Oct 1971] 45927/71 Heading B8C A carrier for a plurality of bottles comprises a pair of side walls 4 and 6 joined by upper and lower walls 5 and 7 having aligned bottle neckreceiving apertures 10 and 14, and a longitudinal foldline 15 or 16 in at least one of the side walls to allow that side wall to be inwardlyfolded along that line towards the other side wall to grip the bottles. The carrier is erected from a cardboard blank by securing a flap 9 to the side wall by adhesive, staples, or interlocking tongues and slots 9a and 9c, Fig. 1, each side wall being provided with a foldline 15 and 16 forming upper wall portions 4b and 6b and lower larger wall portions 4a and 6a. The blank may be provided with an additional apertured panel 7a adapted to underlie the lower wall to form a double reinforced bottom wall. In use, when the erected carrier is pushed down over the bottles, the side wall or walls collapse inwardly along the foldlines 15 and 16 to grip the bottles, the upper wall being displaced towards the lower wall. The side walls may be held in the collapsed condition by adhering or stapling the wall portions 4a and 6a to the upper wall or by interlocking tongues and slots. As shown, tongues 12 around the upper wall apertures engage beneath the bottle ribs A or caps C once the latter have penetrated the apertures to hold the collapsed barrier condition. The fold line or lines 15 and 16 are interrupted by outlines 18 defining tongues 19, which engage beneath the bottle caps or beads A and which are held against the bottles on collapse of the carrier by over-riding panel parts defined between cut-lines 18 and 20. In modifications, the side walls are each provided with additional longitudinal fold lines 15a, 16b adjacent the lower wall, Fig. 7 (not shown), or one side wall only is provided with a foldline therein, Figs. 8 and 9 (not shown). In another embodiment, Figs. 10 and 11 (not shown), a dual carrier for supporting two rows of bottles is formed by two carriers, each similar to that shown in Fig. 8, joined by a carrier handle 30 integral with the lower walls. In modified dual carrier constructions, Figs. 12 and 13 (not shown), the lower or upper walls of the carriers are common.

Abstract: A circuit arrangement is disclosed in which a capacitive unit suitable for a.c. operation is connected in series with an a.c. load. An extension of the life of the capacitors can be achieved by having the capacitor unit consist of two capacitors connected in series either on the same side of the consumer or on opposite sides of the consumer, and that a separate rectifier diode is connected in parallel with each capacitor.
