Title: Measurement of oil or gas content of earth formations
IPC: G01V5/10
Filed: 1973-08-08
Abstract: 1429989 Measuring oil/gas content of earth formations CHEVRON RESEARCH CO 8 Aug 1973 [21 Aug 1972] 37677/73 Heading G1A A method of determining differences in the fractional volume oil and/or gas content of a reservoir earth formation 12 containing oil and/or gas surrounding a well bore 10 comprises (i) obtaining a first neutron-activation oxygen log and thermalneutron-decay-time log (ii) changing the oil and/or gas content of the earth formation surrounding the well bore (iii) obtaining a second neutronactivation oxygen log and thermal-neutron-decaytime log and (iv) calculating the required differences in fractional volume oil and/or gas of the earth formation from the measured difference in oxygen response between steps (i) and (iii) and the determined difference in total thermal neutron capture cross-section between steps (i) and (iii). A sonde 17 supports 7 radiation detectors 24, 26, generator 28 producing 14 MeV neutrons by the deuterium-tritium interaction and detector 30 which measures the 7 radiation produced by decay of unstable O<SP>16</SP> which is formed when the 14 MeV neutrons strike O<SP>16</SP> nuclei to form unstable N<SP>1</SP><SP>6</SP> which decays with a 7À3 second time constant and which emits beta rays to form an excited state of O<SP>16</SP> which emits two 7 rays of 6À13 MeV and 7À10 MeV in returning to stable O<SP>16</SP>. The record of radiation detected by detector 30 is trace 68 on chart 42. Detector 26 is gated to sample γ- radiation produced by decay of thermal neutrons for one millisecond after a burst of fast neutrons has been emitted by generator 28. The measurement from detector 26 is recorded as trace 66 on the chart, by way of cable 19, slip ring assembly 72 oscilloscope 46 and amplifier 56. The oil content is changed by flooding the earth formation or by production of oil from the earth formation. The flooding is done with an alcohol or micellar solution through valve 82, pump 84 and perforations 16 in the well casing 14, the flooding reducing the oil content substantially to zero by displacement. The displacing agent must then be itself displaced by water with a salinity equal to that of the original formation water, because of the large thermal neutron capture cross section of chlorine nuclei. Cleaned formation water can be injected from tank 88 through valve 90. Further detector 24 senses the natural radio-activity, recorded as trace 64.

Title: Method of producing an epoxy resin modified with organic silicon compounds
IPC: C08G59/40
Filed: 1954-12-31
Abstract: Epoxy resins are modified by treating them in solution with a monomeric silane or a mixture thereof of the general formula RnSiX4-n (where R is hydrocarbon radical, X a halogenatom or a hydroxyl, alkoxy, aryloxy or aralkoxy group) or a corresponding partially condensed siloxane containing reactive OH groups, whilst slowly adding 2 to 100 per cent of water based on the silane or siloxane. The mixture is boiled under reflux, water is removed by azeotropic distillation and the resin diluted. Catalysts, e.g. phosphoric acid, sulphuric acid, acetic acid, oxalic acid, alkali and alkaline earth stearates, palmitates and naphthenates, aluminium chloride, iron chloride and alkali and alkaline earth sulphides may be used.  The epoxy resins are condensation products of epichlorhydrin with a polyhydric phenol or a novolak.  In Example 1, an epoxy resin from epichlorhydrin and 4,41-dihydroxy diphenyl butane dissolved in xylene, butanol and acetyl glycollic acid is reacted with phenyl triethoxy silane in the presence of aqueous phosphoric acid.  In Example 2 an epoxy resin from diphenylol propane is reacted with an aqueous butanol-xylene solution of a partially condensed silanol made by hydrolysing diethyl dichlorsilane.  In Example 3, a solution of an epoxy resin from p-tertiary-butyl phenolformaldehyde novolak and epichlorhydrin is reacted with a mixture of phenyltributoxy silane and methyl triethoxy silane.  The products may be used as glass-to-metal adhesives and as a wire lacquer when in combination with phenol or alkyd resins.

Abstract: 1508059 Image pick-up tubes PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 16 Sept 1975 [19 Sept 1974] 38008/75 Heading H1D A TV camera tube includes light source 21 and diffuser 17 between anode sleeve 10 and auxiliary cylinder 15 which at least partially projects into sleeve 10 to a point beyond the light diffuser. Homogeneous as well as non- uniform illumination of target 18 may be achieved to compensate for inhomogeneity in the target sensitivity. Non-uniform illumination may be achieved by profiling the boundary of cylinder 15, making openings, or providing flange 19, or with a non-uniformly transmissive diffuser 17, (e.g. a diffuser with a pattern of black strips, or a continuous or stepwise varying blackening). Diffuser 17 may have matted surfaces and the end faces may be polished, or the diffuser may be of material which diffuses light as it passes therethrough. Preferably the inner surface of sleeve 10 is diffusely reflective, and the portion towards the target may be less reflective. Also to prevent over exposure of the target periphery, sleeve 10 may have a broadened portion near the target. Lamp housing 22 is arranged about narrowed pumping stem 5 or may be arranged against a thicker stem and secured by a cement of a refractive index to limit light losses, a portion 23 of stem 5 providing a lens action. Alternatively the source may be provided in an indentation in the tube. Filter 25 controls source 21 radiation the tube. Filter 25 controls source 21 radiation, and light screen 26 (e.g. a 45 degree cone) limits the loss of light and stray light.

Title: Film metering mechanism
IPC: G03B1/66
Filed: 1963-09-27
Abstract: 1,065,455. Film metering mechanisms. EASTMAN KODAK CO. Sept. 27, 1963 [Sept.28, 1962], No.38124/63. Heading G2A. A film metering mechanism comprises a manually operated film driving means, a film sensing member 35 movable between a first position in contact with the film surface, and a second position wherein it extends through one of the perforations 31 spaced on the film 21 at predetermined metering intervals, and separately energized locking means responsive to the motion of member 35, when it approaches its second position, for blocking the driving means through pawl 63 and ratchet wheel 33 rigidly connected with the film take-up spool. Spring 41 is wrapped round pivot 43 and biases sensing member 35 counter-clockwise about pins 37 which it loosely engages by slot 39. Locking lever 51 carries pawl 63 and is heavily biased clockwise about pivot 43 by spring 53. Lever 51 has a cam surface riding against latching extension 59 of sensing member 35, and has a blocking arm 61 which prevents the depression of shutter release lever 25. As the operator rotates the take-up spool and ratchet 33 anti-clockwise, the film moves until the nose of member 35 enters a perforation 31 under the action of spring 53, the travel of pin 37 in slot 39 limiting this movement. This partial movement of lever 51 shifts blocking arm 61 from the path of shutter release lever 25. Further winding of the film carries member 35 anti-clockwise about pin 37 until latching extension 59 slips over cam surface 57 and locking lever 51 then snaps clockwise due to spring 53 and pawl 63 engages ratchet 33 to lock the winding mechanism. This locking indicates that another exposure may be made without fear of double exposure. A spring-loaded hammer 71 is cocked by the cocking of the shutter mechanism, and when the shutter is released by lever 25, hammer 71 is also released to rotate anti-clockwise and strike locking lever 51. This action overcomes the indirect effect of spring 53 on member 35 which is then moved by spring. 41 away from the film to return to the Fig. 3 position, while pawl 63 is disengaged from ratchet 33 and arm 61 again blocks release lever 25.

Abstract: 918,683. Sintered polytetrafluoroethylene. RESISTOFLEX CORPORATION. Nov. 7, 1960 [Dec. 9, 1969], No. 38222/60. Class 87(2). A process of producing discrete lengths of large diameter thin walled sintered polytetrafluoroethylene tubing consists in extruding the tubing 22 into the space between a pair of telescoped pipes 10, 11, and sintering the tubing while it is freely supported in a horizontal position by the pipes. A bolt 14 passed through apertures at the lower end of the pipes and provided with spacing sleeves 15, 16 positions the structures 10, 11 coaxially. After the required amount is extruded the tubing 22 is clamped to the inner pipe 10 just below the line AA along which it is severed. The assembly is then poistioned so that the tubing is supported horizontally whereupon the clamp is removed and the sleeves 15, 16 replaced by sleeves 23, 24 of unequal length. In addition a second bolt 14 having spacing sleeves 23, 24 is passed through holes 18 to 21. The pipe 10 now supports the upper surface and pipe 11 the lower surface of the tubing 22. The assembly is placed in an oven and the tubing 22 sintered. Equations are given for determining the ratio of the diameters of the pipes 10, 11 and their relative positioning by the sleeves 23, 24. Support may be by segments instead of pipes, Fig. 4 (not shown).

Abstract: 966, 897. Fluid-pressure servomotor control systems. GARRETT CORPORATION. Oct.26, 1961, No.38389/61. Heading G3P. [Also in Division F2] Fluid supplied at 18 and directed between two motor ports 19, 20 and two exhaust ports 21, 22 by a spool valve 23, is also conducted via spool passages 44, 41, 43 to circumferentially spaced longitudinal end recesses 42 between at least some of which are longitudinal pressure relieving grooves 45 communicating with the exhaust ports in all operative spool positions, the recesses 42 being positioned so as not to communicate with any of the ports. In this way frictional resistance to movement is reduced by a thin lubricating film of air flowing around the spool from recess to groove. The spool is shifted by air supply pressure acting on its ends via passage 37 and restriction 38 and issuing from two jets 35 under the control of a vibrating reed displaced by a torque motor 30 in response to electric signals. In a furtner embodiment the spool is shifted against centralising springs by solenoids surrounding its ends and the grooves 45 lead to end casing atmospheric ports via annular connecting grooves 46. The spool controlled liquid or gas or a separate source of fluid may be used for the lubrication.
