Title: Locating fluid saturated zones by applying low frequency excitation and analysing a characteristic resonant response
Inventor: ZUERCHER HANNES
IPC: G01V1/00
Filed: 2009-09-14
Abstract: Actively exciting and analyzing the resonance phenomena occurring in an enclosed oil, gas and or water reservoir allows its presence to be located by doing qualitative and quantitative estimates of its extent via forward modelling. Eight excitation types are covered. Nine qualitative analysis steps are presented. Several specific techniques are used to relate the actual measurement with a numerical or theoretical model based on specific physical concepts, and so arriving at relevant conclusions about the reservoir. A qualitative survey method and a quantitative method based on a numerical modelling in conjunction with the Monte Carlo method are used to relate the oscillation characteristics to fluid properties. Differentiation between fluids is included. The method is directly sensitive to the oil or gas itself, because the resonance effect is only present for a fluid. Gas bubbles can strongly influence results.

Title: Improvements in and relating to the manufacture of artificial aqueous dispersions ofrubber, rubber substitutes and rubber-like substances
IPC: C08J3/05
Filed: 1943-07-01
Abstract: In producing artificial aqueous dispersions of natural and synthetic rubbers, their reclaims or cured or uncured wastes, rubber substitutes (e.g. factice) and thermoplastic rubber-like substances, e.g. butadiene-styrene copolymer, butyl rubber, thiokol, ethyl cellulose, polyvinyl chloride, polyvinyl acetate, polyvinyl acetals, polyvinyl alcohols, polyacrylic esters, organic polysulphides or mixtures thereof, the dispersion is effected without the intermediate step of liquefaction or solution in an organic solvent, by masticating the solid materials until plastic in the presence of a soap, the acid radical of which is saponified by one or more of the bases tetramethyl (or ethyl) ammonium hydroxide, triethanolamine, and benzylamine.  Suitable soap-forming acids are oleic, ricinoleic, stearic, palmitic or abietic acid.  The soaps are either formed prior to their incorporation into the stock or in situ during the dispersing operation.  Prior to dispersion, the materials may be masticated in the same pre-heated internal mixer, if necessary with the addition of reclaiming agents such as rosin, ester gum, coumarone, resin, phenyl hydrazine or with the addition of a small proportion of mineral oil.  The resulting dispersions mix readily in all proportions with natural latex.  The Provisional Specification describes also the use of mono-di- and tri-ethylamine soaps.

In a machine for profiling a blank 8, Fig. 1, with a screw thread &c. the blank 8 is dropped into the throat of a pair of rolls 6, 7, having identical profile surfaces, which are rotated at different speeds so that the blank is drawn through the throat. The tangents at the initial points of contact are arranged at an angle C which is less than the combined angles of friction A + B between the blank and the surfaces of the rolls so that the blank is drawn into the throat immediately it makes contact. The rolls 6, 7, Fig. 4, are keyed at 12 on shafts 10 having screw threaded portions 13 engaged by lock-nuts 14 which permit axial adjustment of the rolls into correct relative alignment. Adjustment of the throat is obtained by screws 20 engaging bearings 11 of the shafts 10. Driving gears 17, 18 are arranged so that one roll is drawn at a slightly greater speed than the other.
Patent GB-820890-A (GB)
Title: Apparatus for and method of lining metal articles
Inventor: WOODRUFF M D
IPC: B05D7/22
Filed: 1956-04-09
Abstract: <PICT:0820890/III/1> A method of lining a hollow article comprises inserting within the article a core adapted to form a cavity or cavities between it and the inside surface of the article, introducing liquid plastic lining material, while preventing air from being entrapped, causing the material to set, removing the core and reheating and cooling the lining material to toughen it.  As shown, the core is in three parts: (i) a baseplate 5 carrying a mandrel 6; (ii) a part 7, also comprising a plate and projecting mandrel; (iii) a part 9 similar in construction to the part 7.  All three core parts are bolted at the marginal areas of their plate portions to flanges 4, 2 and 3 of the body 1 to be lined.  The end face of the mandrel of the part 7 fits closely against that of the mandrel 6 and the end of the mandrel of the part 9 is formed to fit round part of the circumference of the mandrel 6.  The clearance around the core is such that space is left for the plastic material between it and the inside surfaces of the body 1, part of the surface of the mounting flanges and the inside surfaces of their interconnecting conduits. The surfaces of the core are covered with whiting to render the plastic material non-adhesive thereto. The body 1 to be lined is sandblasted and cleaned and immersed in an air-drying primer, e.g. a mixture of vinyl and phenolic resin. A pump 12 forces liquid plastic material, e.g. a vinyl compound, to a header 13 which distributes it by radiating conduits 15, each with a valve 16, to openings in the plate 5 approximately in line with the space between the mandrel 6 and the body 1.  Vents 17 are also arranged approximately in line with the upper end of the cavity to allow air to escape.  The part 9 has vents 18.  When plastic material issues from the vents the pump 12 is stopped, the valves 16 closed and the vents plugged.  The entire unit is then placed in an oven and the temperature rapidly raised and kept at a high value, then reduced to, and maintained at, a lower value, this control of the curing temperature resulting in better adhesion of the lining material.  Relief openings 19 allow for expansion during curing.  The unit is aircooled, the core parts removed, and the sprue trimmed off.  Roughness of the lining, due to uneven detachment from the core, is removed by reheating, the lining being shrouded from the direct heat of the oven by metal plates. This additional curing also toughens the plastic material.  The outside of the body 1 may be coated with similar plastic material by spraying.

Title: Improvements in or relating to electric discharge tubes
IPC: H01J1/13
Filed: 1937-06-19
Abstract: 490,652. Electron multipliers. NAAMLOOZE VENNOOTSCHAP PHILIPS'GLOEILAMPENFABRIEKEN. June 19, 1937, No. 10819/38. Convention date, June 22, 1936. Divided application. [Class 39 (i)] A discharge tube containing a thermionic cathode, one or more grids, an anode and a secondary emission electrode is so designed that the maximum temperature of the cathode during operation is not more than 700‹ C., whereby vaporization of the cathode is reduced to such an extent as to prevent deleterious action of vaporized material such as barium on the secondary emission electrode. The temperature of such a cathode may be rendered more uniform by utilizing a thick cathode surface, by giving it a smaller diameter at the ends, or by winding the heater with a variable pitch. The cathode may be of copper or copper alloy. Emissive material may be removed from those parts of the cathode which do not participate in emission, for example those opposite the grid supports. The emissive material may be a mixture of low volatility, for example, a mixture of 20 per cent barium oxide and 80 per cent strontium oxide.
