Title: Method and apparatus for earth drilling
Inventor: DEVILBISS JOHN
IPC: E21B10/18
Filed: 1970-10-07
Abstract: 1281252 Earth drills SUN OIL CO 7 Oct 1970 [24 Oct 1969] 47580/70 Heading E1F An earth drill bit with a rotary toothed cutter has drilling mud directed through the tooth gaps where the teeth are in contact with the earth. The bit is preferably a roller bit, and the drilling mud flows through passages 26 and down a groove 34 in the external surface of the bit body. This is stated to centralize the bit, where there are, for example, three rollers, because any eccentricity results in a local variation in pressure in the groove 34 and hence in the annulus surrounding the drill.

Title: Chemical analysis apparatus
IPC: G01N21/41
Filed: 1973-10-12
Abstract: 1393849 Chemical analysis GOW-MAC INSTRUMENT CO Inc 12 Oct 1973 [6 Nov 1972] 47691/73 Heading G1A The invention relates to the chemical analysis of a material by its effect on the refractive index of a solvent, using the Christiansen filter effect, viz the difference in variation of the refractive index of solids and liquids with the wavelength of light. As illustrated Fig. 1, (not shown), the solvent (ISO-OCTANE) is pumped through parallel reference and sample tubes. The tubes are packed with grannules (e.g. LITHIUM FLUORIDE which has the same refractive index as ISO-OCTANE at the sodium-D-line, and hence transmits light without dispersion at this wavelength). The sample is injected into the solvent flowing through the measuring tube, and collimated light is projected through the tubes on to respective photo-sensors (e.g. photo-FET's), whose outputs are compared. Fig.4 illustrates the variation of refractive index with wavelength for the solid particles 55, pure solvent 57 and the solution 70. This shows the twc transmission bands around #1 and #2 for the reference and sample tubes. Since the total transmission increases with wavelength the relative amplitude of the signals may be used for measurement. Fig. 2 (not shown) illustrates a mono-block cell construction with two parallel bores closed at the ends (axially) by glass discs and screwed bushes. The light in the diffusion "halo" instead the direct beam may be measured by blanking-off the centre of the photo-sensor Fig. 3 (not shown).

The pH value of a primary cell having sal ammoniac solution as electrolyte and pyrolusite as depolarizer is stabilized by adding to the depolarizing composition an alginic acid gel or an alginated or a mixture of these. Ammonia is absorbed by the gels, which are converted to fairly thin fluid sols, examples being zinc, aluminium, magnesium, manganese, calcium and alkaline earth alginates. Preferably a metal alginate is used which forms an amine complex salt with ammonia. The gels form thin membranes, containing additives such as carbon black, which membranes envelope individual portions of the electrodes which are disposed concentrically or axially adjacent one another.

Abstract: A grease composition is produced by subjecting to homogenization at 15 DEG  to 77 DEG  C. a lubricating oil, e.g. a mineral oil and a minor proportion of a pulverulent spray-dried oil-dispersable clay product passing a 250-mesh screen U.S. standard which comprises a high base exchange clay bearing on its surfaces 40-100% by weight, based on the clay, of an oleophilic nitrogen compound selected from hydrocarbyl-substituted imidazolines, amino amides formed between fatty acids and mixtures of polyalkylene polyamines, and mixtures of these imidazolines and amine amides, the clay product having a moisture content of 0.5-5.0% by weight and being free from oil (see Division C1).  The oil may contain a small amount of water to improve yield and milling characteristics and sodium nitrite to improve anti-corrosion properties.  The oil may contain an additional amount of hydrocarbyl-substituted imidazolines and amino amides formed between fatty acids and mixtures of polyalkylene polyamines, the amount of oleophilic nitrogen compound on the clay being at least 60%.ALSO:An oil free, pulverulent oleophilic clay product is prepared by (a) forming a hydrosol of a high base exchange clay, i.e. between 60 and 100 milliequivalents of exchangeable base per 100 grams of clay, e.g. hectorite, (b) adding a mineral acid, e.g. phosphoric acid in an amount equal to the base exchange capacity of the clay, (c) adding 40-100% by weight based on the clay of an oleophilic nitrogen compound selected from hydrocarbyl-substituted imidazolines, amino amides formed between fatty acids and mixtures of polyalkylene polyamines, and mixtures of these two, (d) spray drying the mixture so obtained at 150-760 DEG  C. to a product passing a 250-mesh screen, U.S. Standard, and having a moisture content of 0.5-5.0% by weight of water.

Slots 21, 22 in armature are coated with insulating material by blowing powder through apertures in a coating member 31 in a series of separate streams one directed into each slot and allowing the powder to melt and subsequently set on the previously heated armature. The powder 43 is contained in a vessel 44 and air passing through a pipe 47 and a porous member 46 produces a fluidised bed. The powder falls to the vicinity of holes 58 through which it is blown by air from a tube 39. It then passes between plates 67 to the slots 21. Coolant is passed between the spaces of the plates 67 from annular chambers 71, 72 which connect all these spaces together thus preventing melting of the powder until it contacts the armature. Excess powder emerges at the top and bottom of the armature from the slots to coat the upper and lower surfaces. Further coolant chambers 81 are provided for these surfaces. The coating member may be vertically oscillated to produce an even covering of material throughout the slots. When the nozzles are near the end face of the core some of the material 42 will travel axially beyond the confines of the slot and coat the end face this coating being controlled by wall 76 which directs the powder towards the end face. Excess powder is collected by a collector 86.
