Title: Method for the construction of concrete blocks for use in subaqueous building operations and floating dock for the performance thereof
IPC: E02D27/06
Filed: 1925-10-20
Abstract: 264,580. M³ller, J. Oct. 20, 1925. Walls; floating docks.-Concrete blocks for subaqueous buildings are constructed upon a submersible floating support of permanent inherent buoyancy, the submersion of which to enable the block to be floated out is controlled by positive mechanical means, preferably the means by which the support is anchored. The support consists of a floating dock, preferably built of wood or otherwise rendered permanently buoyant, and having a flat bottomed hull and elevated decks and bridges. Submersion of the dock is effected by winding up the anchor chains upon windlasses, assisted by the flooding of the hull. The hull of the floating dock is formed by a flat bottom 1, Figs. 1 and 4, sidewalls 2 and a stern 3, with a roofed compartment 6 at the prow communicating with the main deck 1 by means of watertight doors. Astride of each wall 2 of the hull are erected upon two turrets 9 two lower platforms 10<a> and two upper platforms 10. The platforms 10 of each side are connected by a gangway 11. Above the stern 3 is a platform 12 which serves as a terminal for an aerial conveyer 13, Fig. 2. On each of the platforms 10 is mounted a windlass 14, each carrying a chain 17 secured to an anchor 16 consisting of a loaded chest. Sea-cocks 22, 23, Fig. 4, are provided to flood the dock. A skeleton framework for a stage formed by joists and beams 18 supported on uprights 19 is erected as a permanent structure on the bottom of the dock, removable panels 20 being supported thereon to form a platform. Upon this platform is built the concrete shell comprising a bottom A and walls B. Adjustable scaffolding 24, 25, Fig. 2, may be provided. As the construction of the shell proceeds, the draught of the dock increases, and the shell may at the same time be loaded with ballast or concrete. When the water level rises to the point indicated by the line 31, Fig. 4, the sea cocks are opened so that the dock is flooded though still floating. The dock is then submerged, by winding in the chains 17, sufficiently to allow the block shell to be floated out over the submerged stem or prow. During this operation the decks or bridges 10, 11 are still above water. The anchor chains are then unwound from the windlasses 14, and the dock rises to its normal level, the water therein escaping through the still opened sea cocks.

Title: Polytetrafluoroethylene fibres and filaments having reduced  electrical resistance
IPC: C08K3/04
Filed: 1972-06-06
Abstract: 1384016 Polytetrafluoroethylene filaments HOECHST AG 6 June 1972 [18 June 1971] 26330/72 Heading B5B [Also in Division C3] A filament comprising polytetrafluoroethylene and particles of an electrically conductive material, especially an electrically conductive pigment, is made by spinning a solution containing these constituents, and preferably also cellulose or a cellulose derivative. The nature and the amount of the conductive material are chosen to give an electrical resistance in the range specified below.  After spinning the filament may be heattreated to cause mechanical hardening or sintering of the filament. Specified conductive pigments include carbon black, graphite, and metals especially copper, iron and nickel. The grain size of the material, which may comprise at least 10% of the weight of the filament, preferably does not exceed 100 microns. Mixtures of pigments may be used, especially of carbon black and graphite. A dispersion containing a conductive pigment may be introduced into a spinning solution containing a PTFE dispersion, optionally in emulsified form. Also suitable are spinning solutions in which organic substances are used for thickening the PTFE dispersions, and spinning solutions spun in gelled form. Alternatively, conductive pigment may be mixed with PTFE powder, or the mixture suspended in gasoline, higher boiling mineral oil or in a plastifier substance, e.g. dimethyl phthalate and the paste so formed extruded through a nozzle. In the example, a viscose solution is mixed with a PTFE dispersion, a non-ionic dispersing agent, and carbon black to form a spinning solution containing total solids comprising 7% cellulose, 16% carbon black and 77% PTFE, which is spun into a coagulating bath containing sulphuric acid and sodium sulphate. The wound filament is drawn at 380‹ C. and rewound. Filaments so made show substantially uniform distribution of the electrically conductive material across their cross-section and have a maximum electrical resistance of either 1000#/ cm.dtex. or a thousandth of the electrical resistance of a corresponding PTFE filament which does not contain electrically conductive material, whichever is the lower. Thus the filament exemplified shows an electrical resistance of 10<SP>4</SP>#/cm. while a similar filament containing no carbon black shows a resistance of more than 10<SP>9</SP>#.

The invention relates to adipic acid derivatives of the formula in which R 1  and R 2  denote alkyl groups of 1-6 carbon atoms or, with the carbon atom to which they are linked, form a cyclopentyl or cyclohexyl ring. The esters are obtainable by a process in which (1) an ester of the formula in which R 3  denotes an alkyl group of 1-6 carbon atoms, is reacted with zinc and an ester of the formula BrCR 1 R 2 COOR 4 , in which R 4  denotes an alkyl group of 1-6 carbon atoms, to yield a lactone of the formula (2) the lactone is treated with aluminium chloride in nitrobenzene and then esterified to yield an unsaturated diester of the formula and (3) the ester is reduced, suitably by hydrogenation in the presence of a palladium-carbon catalyst, and then hydrolysed to yield the dicarboxylic acid. Examples are given describing the preparation by this method of 2,2-dimethyl- 3 - (p - methoxyphenyl) adipic acid, 2,2 - di - ethyl - 3 - (p - methoxyphenyl) adipic acid and 4 - (1<SP>1</SP> - carboxy - 1<SP>1</SP> - cyclopentyl) - 4 - (p - methoxyphenyl) butyric acid. Ethyl α-bromocyclopentane carboxylate, used in preparing the product of the final example is obtainable by refluxing cyclopentane carboxylic acid with thionyl chloride and adding excess of bromine.

Title: Process for the preparation of acylaminocarboxylic acids
IPC: C11C3/00
Filed: 1957-08-27
Abstract: A process for the preparation of acylaminocarboxylic acids comprises reacting a lactam which contains 5 to 9 carbon atoms in the lactam ring with a free carboxylic acid, which contains at least 8 carbon atoms in the molecule in the ratio 1 to 10 mol of lactam per mol of carboxylic acid at temperatures between 150 and 300 DEG C. in the presence of an inert gas.  The products of the reaction are represented by the general formula:  <FORM:0858238/IV(b)/1> in which R is an organic, preferably a non aromatic hydrocarbon, residue which contains at least 7 carbon atoms, n is a whole number from 3-7 and x is a whole number not more than 10. Compounds with amino carboxylic acid residues in polyamide-like combination are formed primarily when the lactam is used in more than equivalent amounts relative to the carboxylic acid. Water-soluble salts of the products containing non-aromatic hydrocarbon residues with at least 8 e.g. 8-26, preferably 10-20 carbon atoms and in which x is not greater than 5 are whitening agents.  Lactams specified include butyrolactam, valerolactam, and octanoic acid lactam and N-hydrocarbon substituents containing 1-3 carbon atoms may be present in the lactams. Carboxylic acids specified include caprylic, pelargonic, capric, undecylic, lauric, palmitic, stearic, oleic, linoleic, behenic acids resin or naphthenic acids, e.g. abietic acid diphenylcarboxylic, triphenylcarboxylic, alkyl or cycloalkyl, benzyl benzoic, benzyl naphthoic acids and substitution products, especially alkyl derivatives thereof and complete or partially ring hydrogenated derivatives thereof.  Ethercarboxylic acids, e.g. those derived from glycolic acid, or by reaction of alcohols with halocarboxylic acid salts especially chloracetic acid salts in the presence of acid-binding agents may also be employed as starting materials. Inert gases mentioned include carbon dioxide, nitrogen and water vapour.  Increased pressures may be employed in the process and small amounts of water may be added to the reactants.  Some products may be purified by fractional crystallisation as distillation of the methyl esters.  Examples relate to the production of acylaminocarboxylic acids by heating caprolactam with lauric acid (1-5) or stearic acid (6-9).  In Example (1) the product may be recrystallised from ethanol and the crude or purified acid converted to a water-soluble salt by neutralisation with caustic soda or potash solution, or mono-, di-or triethanolamine and in Example (2) the product is converted to a salt by reaction with sodium, potassium or guanidine carbonate.
