Abstract: 1492823 Well-logging HUGHES TOOL CO 5 Feb 1975 4903/75 Heading G1G [Also in Divisions El G3 and G5] The specification describes a method and system for determining the three dimensional position of the bottom or selected points in a borehole which is being drilled by a rotary bit, in combination with a fluidically powered, by the drilling fluid pumped down the borehole, acoustic vibration generator comprising a fluidic amplifier and acoustic cavity, the acoustic vibrations from which being detected on the surface by detectors at a plurality of spaced points to produce and record the received waveforms, the phase differences between which are compared and used calculate the said position. The detecting system comprises at least five geophones G o , G i  ... G n  coupled to the ground at locations (x i , y i , z i ) to receive the acoustic vibrations from the acoustic generator 70 along paths P o , P i , ..., P n  of varying lengths. The rotary drilling may be suspended during this measurement to reduce received noise. The received signals are amplified via A o , A i , ..., A n  and fed to recorder 607 where they may be recorded in analogue or digital form. The phase difference between the received signals may be measured manually from traces TR i  or by electronic equipment 605. The position co-ordinates (X, Y, Z) of the drill bit 69 may be computed on site by computer 607 using digital iterative techniques. A mathematical treatment is used to present the outline of the computation.

Title: Improvements in and relating to expansion apparatus for rendering visible the paths of ionizing particles
IPC: G01T5/04
Filed: 1921-02-16
Abstract: 177,353. Shimizu, T. Feb. 16, 1921. R÷ntgen-ray and like apparatus.-Relates to apparatus by means of which the tracks of an ionizing agent passing through a gas are rendered visible by condensation of saturated vapour upon the ions produced by the agent, the supersaturation being produced by expansion of the previously saturated gas. The invention consists essentially of an instrument whereby a continuous succession of expansions and contractions is produced so that the tracks of the ionizing agent can be observed in a regular succession of intermittent intervals. The ionizing agent may consist either of the emanations from a radio-active substance, or of X-rays. The apparatus comprises a vertical metallic cylinder a containing a piston b and having at its upper end a transparent extension c closed by a transparent disc d, an electrically-conducting ring e being interposed between the parts c, d. The piston carries an extension f fitting the cylinder and is continuously reciprocated by the lever j pivoted at k to the piston-rod g. The free end of the lever passes through a block m which can be adjusted along a screw n to vary the stroke of the piston, while the end j<2> of the lever is adapted to be rocked continuously by its connection to a connecting-rod p operated by a shaft q geared to a countershaft r adapted to be rotated by hand or mechanically. The gas in the extension c is maintained in a saturated condition by coating the lower surface of the disc d and the upper surface of the member f with moist gelatine, the latter surface being preferably blackened by mixing ink with the gelatine. Means are provided for intermittently creating an electric field between the conducting-ring e and the member f in order to dispel the existing ions before a fresh ionization occurs. On the shaft q is mounted an insulated contact-disc t including a separated earthed sectors. The electrical connections include a fixed brush y connected to a source of potential and bearing always on the disc t and a radially-adjustable brush v connected to the ring e bearing alternately on the disc t and the sector s. The sector s is so shaped that the relative intercepts of the disc and sector on a circle concentric with the axis of the shaft q vary with the radius of the circle so that the duration of the field can be adjusted by adjusting the brush v. The extension c may be observed through an aperture 7 in a disc 6, or a series of photographs may be obtained. When the ionizing agent is a radio-active substance it is placed in the cylinder, and when X-rays are used they are passed through the transparent extension. A shutter device for use with X-rays comprises lead pieces w, w secured to the disc x carried by the shaft q, one of the members w being adjustable by a clamping-screw w<1>.

Abstract: 474,127. Wick burners. LAMPENUND METALLWARENFABRIKEN R. DITMAR GEB. BRUNNER AKT.-GES. Feb. 23,1937, No. 5396. Convention date, Feb. 28, 1936. [Class 75 (i)] An incandescent wick burner comprises a perforated gallery 4 supporting a perforated cone 11 having a vertical extension 10 carrying an integral partition wall 12 formed by a perforated horizontal portion, a perforated conical portion 18, and an apertured horizontal shoulder 14 which forms a height-stop for the wick 5 and supports a perforated burner cap 13 having a depending sleeve 30. A perforated cone 21 secured by a bayonet joint 20 to the gallery 4 makes contact with the vertical extension 10 and has its upper portion formed as a hood 28 having an inturned rim 29. The incandescent mantle is carried by a cone 23 having an inturned perforated rim 25 and fitting over an annular member 21<1> carried by the cone 21. The cone 21 also supports a gallery 22 for the glass chimney 22<1>. When the burner is ignited the vapour generated at the lateral surfaces of the wick passes through the perforations 17, 31 in the wall 12 and mixes with primary air supplied through perforations in the wall 12 and secondary air supplied through the hood 28, cone 23, and cap 13 to produce a non-luminous flame which heats the mantle to incandescence. A restriction b in the passage between the hood 28 and cone 23 prevents an excessive speed of air flow. All the parts in contact with the burner flame are at a distance from the wick tubes 6, 7 so that the transfer of heat to the fuel container is prevented. The hood 28 may be secured to the partition wall 12 instead of being carried by the cone 21.

Abstract: 926,031. Control of electric hot plates. STEVENS MANUFACTURING CO. Inc. Feb. 14, 1961 [March 2, 1960], No. 5447/61. Class 39 (3). [Also in Group XXXVIII] A device for sensing the temperature of a vessel on a surface heating unit consists of a sensor body having a flanged head and depending shank which is slidable in an L-shaped bracket under the influence of a spring round the shank so that the head of the body is forced against the vessel being heated. Fig. 2 shows a spiral heating unit 12 the ends 14 of which are mechanically connected to a terminal block 16 to which either flexible or separable connections are made. The L-shaped bracket 26 supported at 21 from the terminal block 16 passes through an aperture in the drip plate 17 and carries an apertured portion 29 in which is mounted the sensing unit. The sensing unit which is substantially identical to that disclosed in Specification 926,033 consists of an insulating body 35 with a flanged head 36 and a shank 37. A spring 38 between portion 29 of the bracket and flange 36 forces the sensing unit upwards into engagement with the bottom of the pan. A snap ring 39 limits its upward movement. The temperature of the vessel is detected by a double spiral resistance situated between an aluminium cap and a washer on a shank depending from this cap.

The shaft is driven, through a oneway ratchet device 20, 21, by a dog 14, and is traversed axially, with the centres &c. at the speed of one groove 48 for each revolution. The tool is keyed to rings 30, 31 mounted on a sleeve 24, supported by a non-rotating sleeve 36 in which the shaft 12 is rotatable, the sleeve being secured to a ring 38 having a tail 39 engaging the V-edge of a fixed member 41, and the tool is rotated by a sleeve 23 secured to the shaft 12 and provided with dogs 29 engaging dogs 28 on a ring 27 secured to the sleeve 24. On the sleeve 36 is secured the profile ring 45 of a cam member, the other ring 46 of the cam member being secured to the sleeve 24, and balls 47 being located between the rings, which are pressed together axially by a spring 42. The cam is so formed that as the tool 11 is fed axially with the shaft 12, it is fed back at the same speed by the cam, so that it remains stationary axially until the end of the groove 48, that is, the longitudinal groove 50, is reached, when the cam allows the spring suddenly to return the work in the direction of feed, thus bringing the next groove 48 into position to be ground. In place of the grinding- wheel, a lathe tool may be used.
