Title: Method of investigating well blast conditions
IPC: E21B47/10
Filed: 1969-07-04
Abstract: 1,237,050. Acoustic inspection devices. MOBIL OIL CORP. 4 July, 1969 [5 July, 1968], No. 33862/69. Heading H4D. A method of investigating a cased well including a tubing string 23 (Fig. 1) extending through a producing zone 14 comprises positioning a sound detector 30 inside the string adjacent the zone and monitoring the sound created by the impingement of the well production stream from the producing zone on the exterior of the string. Hence the possible clogging of perforations 28, resulting in excessive flow velocity of the well stream through unclogged perforations and consequent abrasion of the tubing string, can be detected. In the dual completion well shown, two production zones 14, 16 are packed-off at 24, 26 and feed tubing strings 22, 23 independently. Zone 16 is shut off during the investigation, while detector 30 on support/conductor line 32 is moved in steps or continuously along string 23 and detected signals are fed to surface logging equipment. At the surface the signals are amplified at 40 (Fig. 2), rectified at 42 and fed to chart recorder 44. Sheave 33 provides depth synchronization of recorder 44 and operates depth indicator 52. An adjustable frequency-filter 48 may be used to eliminate irrelevant noise signals and its effect can be monitored on oscilloscope 51 whose trace may be photographed. In various modifications detector 30 output may be displayed on a meter whose readings are recorded as a function of depth, fed to earphones, or magnetically recorded for later playback and visual readout or for frequency analysis or signal enhancement on a computer, and the sound parameter logged may be the peak amplitude, the average amplitude or the root mean square amplitude. Detector 30 may comprise a radially-sensitive lead zirconate cylindrical transducer and may include the rectifier 42.

According to Fig. 2, a sleeve 19 splined at 20 to an input shaft carries the member 22 and the annular piston 28, the member 25 is splined at 24 to the sleeve, and a similar assembly 34, 35 also coacting with the member 38 is mounted on an output shaft 33. A second member 38 is also provided, and both members 38 are pivoted simultaneously about the point 53, or about axes spaced on either side of the axis 51, by a shaft 50 with arms 49. Hydraulic pressure applied to the clamping means may be dependent on transmitted torque, and may be different at the input and output sides of the gear. The clamping means may alternatively be pneumatic or constituted by torque-responsive ball or roller camming means, or a spring. The gear may be associated with planetary gearing in an arrangement in which the input shaft 16 is extended to drive a sun-wheel, the shaft 33 drives a ring gear, and the output is taken from a planetary carrier. Alternatively, the shaft 33 may drive the sun-wheel, whilst the ring gear is fixed and the output taken from the planetary carrier, or vice versa. Fig. 4 shows a modification in which the input shaft 60, perpendicular to the plane of the Figure, drives a sleeve 62 through bevel gearing 61 and a pair of members 67, 68 splined to the sleeve 62 coact with members 74, 75, 76 on the output shaft 73. The member 75 is fixed axially but the members 74, 76 are movable under the influence of torqueresponsive ball-cam arrangements 79, 81. The curvature of the co-operating surfaces is such that in the two extreme positions of adjustment drive is transmitted in the regions q 1 , q 1 , and q 2 , q 2 , respectively. This arrangement provides a large change of velocity ratio for a small adjustment of the members 67, 68. A second set of members 67, 68 coacting with the members 74, 75, 76 may be provided.

Title: Improvements in or relating to processes of heat recovery between gas humidification and de-humidification processes
Inventor: PRATT HENRY REGINALD CLIVE
IPC: B01D47/06
Filed: 1956-11-09
Abstract: In a process in which gas is "humidified", such as by passing it at S, Fig. 2, into a tower F, undergoes a chemical treatment at G, such as a steam/hydrogen process for enrichment of hydrogen in deuterium and is subsequently dehumidified, such as in a tower H before leaving at T, both the humidification and dehumidification processes are each carried out in at least two successive stages so that the operating lines b, c, d and B, C, D, respectively, Fig. 4, on a diagram representing the relationship between the total heat content of the humidified gas and the heat content of the liquid, such as water, which humidifies the gas or is condensed therefrom, more nearly approximate the saturation curve without intersecting it than would a single operating line.  The term "humidify" refers <PICT:0881941/III/1> <PICT:0881941/III/2> <PICT:0881941/III/3> to partial or complete saturation of a gas with a vapour of any liquid. The liquid in tower F is circulated by pump K through heater D, or steam may be injected instead of using heater D, and pump L circulates the liquid in tower H through cooler E, pumps M, N, and heat exchangers A, B, C, ensuring heat exchange between the liquid in the bottom of tower F and top of tower H and so on. Alternatively heat exchangers A, B, C, may be omitted and liquid circulated directly between corresponding sections of the towers. In a modification the tower H is omitted and the gas passes from the chemical treatment G to a series of cooler condensers such as A, B, C.  In a further embodiment, Fig. 3, ammonia synthesis gas is fed into heat exchangers D, C, B, so that liquid nitrogen, the "humidifying" liquid, is condensed under a pressure of 5-10 atmospheres.  After the hydrogen has been enriched in deuterium in process G, and also expanded, it is passed up tower F where the nitrogen is re-evaporated.  Reference has been directed by the Comptroller to Specification 815,098.

[Class 82(ii)] Graded or ungraded pulses are separated in a vessel through which a flotation liquid of uniform specific gravity flows continuously at a low velocity and the sunken and suspended pulses are removed in two or more portions with the aid of swiftly flowing delivery currents directed upwards to a point in the vicinity of the place of delivery of the floating portion. As shown, peas fed into the left-hand side of a body of liquid 3 are carried by a slow current to the outlet side, the sloping bottom 2 of the vessel allowing the speed of the current to slow and separation to take place. The floating peas are removed over a weir 9, the suspended ones passing through an outlet between partitions 6 and 7 and the sunken ones through an outlet between partitions 7 and 8. The peas passing through each outlet are delivered to dewatering screens which may be side by side, the liquid being returned to the inlet end of the apparatus by means of a pump 4. The peas may be thrust below the surface of the liquid by a fluted roller and made to take a tortuous course, Fig 5, (not shown). The bottom outlet may be controlled by a plug, Fig. 6, (not shown), and the speed of discharge from the bottom may be assisted by a jet of air or liquid, Fig. 7, (not shown).
