Title: Gravimetric detection of anomalies lateral to boreholes
IPC: G01V7/00
Filed: 1971-05-11
Abstract: 1336247 Prospecting CHEVRON RESEARCH CO 11 May 1971 [27 July 1970] 14324/ 71 Heading E1F The lateral distances of a gravimetric anomoly from an adjacent borehole are determined by:- Obtaining the density of the formations surrounding the borehole at successive points along the borehole and over the interval under study; traversing a gravity-responsive instrument along the borehole over the interval to obtain measurements of gravity at different depths; obtaining gravitational penturbation effects at different depths from the differences of the measured values of gravity, and the values of gravity at corresponding depths where no anomoly is present and determined from the density measurements; and computing the lateral distances over the interval from the penturbation effects. The density is measured by a gamma-gamma densilogger, or obtained from core samples or computed. The invention is used to determine the shape of the flank of a salt dome so that further boreholes may be drilled for the recovery of oil which may be trapped in sands adjacent the flank. The invention may also be applied to determine the distance of a single bed of sand not intercepted by the borehole, or to determine the extent of a sand bed that has been intercepted by the borehole.

Title: Improvements in and relating to ship raising devices
IPC: B63C7/06
Filed: 1920-05-26
Abstract: 165,308. Green, J. A. May 26, 1920. Sunken ships, raising. - A lifting-device for raising sunken ships provided with means for generating gas in its interior to expel the water comprises a cylinder having a spring-controlled outlet valve, and a valve opened by the pressure of the gas acting on a piston to allow the water under pressure to act on and open the outlet valve. The device consists of a cylindrical body 1, Fig. 1, and a cap 2 comprising a closed air chamber 6 and a central cylinder 5, the upper part of which has a flared extension 7 closed by a cover-plate 8 carrying a spring-pressed valve 12. The lower end 4 of the body is provided with a central tubular extension 16 with outlet ports 17 normally closed by a spring-pressed valve 18. The sides of the body are extended downwardly and flanged, the flanges having holes for the attachment of lifting-chains 43. A cage 21, consisting of a piston 22 which slides in the cylinder 5, plates 23, 24, and rods 25, slides in the body, and carries the acid-container 26. The piston 22 has ports 28 in its walls which allow gas to pass when the piston rises into the extension 7, and carries a projection 30 adapted to be engaged by spring-controlled catches 31 to retain the cage in raised position. The lower plate 23 of the cage carries a rod 33 to which is secured a valve 34, Fig. 3, consisting of a body 36 with a stem 37, a perforated valve plate 39 sliding on the stem 37 and adapted to rest on a seating 35 formed in the extension 16, and a spider 38 secured to the lower end of the stem. A guideplate 40 on the rod 33 slides between pins 41 integral with the body 1 and prevents lateral movement. Before sinking and attachment to the sunken ship, the cylinder 1 is filled with a solution of soda through the valve 48. The filling-cap 45 of the container 26 holds a capsule 46 of soluble material containing soda, and the sulphuric acid in the container dissolves the capsule and acts on the soda, producing carbon dioxide. The pressure blows out the stopper 47 and the acid mixes with the soda solution in the cylinder, generating more gas which acts on the underside of the piston 22, which is thus raised and held up by the catches 31. The first movement of the cage lifts the body 36 of the valve 34 off the valve-plate 39, permitting the pressure to open the valve 18, discharging the water and rendering the cylinder buoyant. Further movement causes the spider 38 to lift the plate 39 off its seat 35 and permit a greater opening. Excess pressure is relieved by the valve 12, the gas passing through the ports 28 in the piston.

Title: Process and apparatus for the production of melamine
IPC: B01J3/04
Filed: 1960-04-28
Abstract: Melamine is prepared by heating a concentrated solution of dicyandiamide or cyanamide in liquid ammonia to a temperature of between 140 DEG  and 160 DEG C. in a closed vessel to provide a saturation vapour pressure not exceeding the critical pressure of pure ammonia (viz. approx. 111 atmospheres), in order to ensure that the operation takes place in the liquid phase, and maintaining this saturation vapour pressure by regulation of the temperature until the temperature corresponding to the said saturation pressure has fallen to 128 DEG  to 135 DEG C.  Prior to the reaction an inert solvent boiling above 135 DEG C., miscible with ammonia and dissolving dicyandiamide or cyanamide readily but melamine only with difficulty, may be added to the ammonia solution of the reactants.  Evaporation of ammonia from the final product then yields melamine and a solution of cyanamide and/or dicyandiamide in the solvent.  Dimethyl formamide is specified as a solvent for this purpose.  Alternatively, melamine may be washed out of the resulting solution in ammonia with a solvent such as water, leaving a solution of unreacted cyanamide and/or dicyandiamide in ammonia, which can be recycled.  The process may be adapted to continuous working, preferably in a manner such that the process temperatures are adjusted by a pressure-controlled cooling system. Specifications 466,957 and 598,533 are referred to.
