Title: Well-logging method
IPC: G01N23/221
Filed: 1972-09-08
Abstract: 1364573 Borehole logging apparatus TEXACO DEVELOPMENT CORP 8 Sept 1972 [20 Sept 1971] 41710/72 Heading G1A In borehole logging, water saturation of earth formations surrounding the borehole is calculated from determinations of (a) the fractional content of sandstone and limestone in the formation matrix, (b) the porosity of the formation and (c) the carbon/oxygen counts ratio in the inelastic gamma ray energy spectrum (gamma rays resulting from inelectric scattering of high energy neutrons bombarding the formation). As shown in Fig. 1, a conventional sonde 7 is operated under control of time reference 39 so that 5 Ásec neutron pulses are produced from an accelerator (deuterium-tritium reaction) source 11 (curve 33); Fig. 2 at 5, 000 to 20, 000 times per second. So as to consider only the inelastic gamma ray population 31, and disregard the thermal neutron capture gamma ray population 32, the scintillation detector 10, 12 has its output gated at 22 to the analyzer 24 only during 7 Áses periods 34. Spectrum stabilization may be carried out at 23. The pulse height analysis is carried out for four energy bands: Si for silicon, from 1À65-1À86 MeV encompassing the Si 1À78 MeV peak; Ca for calcium, from 2À5-3À3 MeV, encompassing the single and double escape peaks but not the Ca 3À73 peak since this is marked by carbon; C for carbon, from 3À17-4À65 MoV, encompassing the C 4À4 Mov peak; O for oxygen, from 4À86-6À34 MeV, encompassing the 6À13 MeV oxygen peak. The count rates in these bands are used to provide the quantities (a), (b) and (c) above, as follows: (a) is calculated from the ratio of the Si and Ca counts (obtained at 26) and from calibration values for pure water sandstone and limestone; (b) is calculated from any one (preferably the carbon) analyser output (or more than one) from a known formula for porosity; (c) is obtained by ratioing device 25. The quantities (a), (b) and (c) are all recorded graphically simultaneously with the water saturation as the sonde moves through the borehole. Alternatively, the analyzer outputs themselves are recorded and applied subsequently to a computer.

Patent GB-1012472-A (GB)
Title: Improvements in or relating to vitreous materials
IPC: C03B19/08
Filed: 1961-11-24
Abstract: To increase the thermal insulating properties of a vitreous material of closed cellular structure, the material while still in a molten state is subjected to pressure or stretching or a combination of the two forces in mutually perpendicular directions, whereby the cells become compressed or stretched or both, the height of the cells in the deformed material being reduced to a relatively considerable extent with respect to their original form.  Deformation may be such that the cells resemble hollow fibres.  The deformed material may be further treated, to roughen at least one surface, by placing the material while still plastic in contact with granular material, such as sand, of higher melting point so that the granular material becomes embedded on the surface.  Tiles or bricks of the material can then be more easily cemented to other surfaces.

Abstract: 1,169,023. Moulding on cores. MICHELIN & CIE (Compagnie Generale des Etablissements Michelin). 27 Sept., 1966 [27 Sept., 1965; 27 May, 1966], No. 43135/66. Heading B5A. [Also in Divisions B8 and E1] An inflatable bag for supporting loads is made by wrapping lengths of cord or plies of parallel cords embedded in an elastomer round at least three sides of a pre-formed core to form a number of superimposed layers such that at any point the cords run in two and only two different directions except that, to provide stiffness at a corner or edge of the bag, additional reinforcing cords having an orientation different from the two orientations of the cords of the superimposed layers may be provided at or in the immediate region of that corner or edge. In Fig. 6 a flat neoprene core encased in an expanded polystyrene envelope 12 is provided with an air-impermeable elastomeric coating 14. A space 11a in the core 12 is in communication with ducts A and B in the coating 14 for the introduction of an inflating liquid and the evacuation of air from the core. Bands 16, of say steel wires bedded in an elastomer, are then wrapped around the core. In Fig. 6 each turn is independent of the next turn, the overlapping ends 16<SP>1</SP>, 16<SP>11</SP> of a turn being lap jointed. The joins of adjacent turns extend diagonally across the body. When one layer has been applied the next is laid on in a different direction. The bag is then coated in a layer of rubber and vulcanized to destroy the envelope 12. The core 11 can be made to disappear during the vulcanization or, before vulcanization, by some other process such as dissolution in a mixture of turpentine and ethyl acetate. The bands 16 need not be individual bands, but continuous bands in helical side-by-side relationship. The bands 16 need not define the bottom of the bag in which case the bottom is defined by a rigid plate. The plate may be of metal or an elastomer and may have ribs that prevent total flattening of the bag.

Title: Apparatus for controlling centrifugal compressors
IPC: H02P29/00
Filed: 1973-09-20
Abstract: 1452771 Centrifugal compressors OWENS-ILLINOIS Inc 20 Sept 1973 44173/73 Heading F1C [Also in Division G3] An electrically driven centrifugal compressor 48 has an inlet valve 46 positioned by a control signal which is normally the difference between the actual output pressure and a desired value but which is modified if the motor current approaches a maximum value in order that that value is not exceeded. As shown, the control signals are pneumatic, but they may alternatively be electric. Output pressure is applied via line 64 to a device 66 which modulates the pressure from a control air source 60 via a manifold 62. If this source fails a valve 116 admits air from line 64 for control purposes. The output of 66 is led to a comparator 72 where it is compared with the desired pressure, the resultant error signal being boosted at 84 to  control the inlet valve 46. The motor current is measured at 80, the electrical signal being converted into a pressure signal at 78 where it is also compared with the set maximum value and the difference used to modify the output of comparator 72 if necessary. The system also has means for preventing surges; this comprises a second motor current detector 98 whose electrical signal is converted to pneumatic pressure at 96 for operation of a controller 102. This normally provides a high output to keep a blow-off valve 56 closed, but as the motor current drops towards a predetermined critical value the controller 102 progressively opens 56 until it is fully open just before the surge point. The pneumatic control elements are not described in detail, but Figs. 1 and 3 (not shown), illustrate electrical relay circuits for starting the compressor from rest (which includes a number of safety interlocks related to parameters such as oil flow and temperature) and also for continuing stable operation during short power failures, e.g. 5 seconds, after which full control is automatically resumed. During such failure a control by-pass 89, 90 is operable.
