Title: Two-receiver variable-density logging system
IPC: G01V1/44
Filed: 1975-07-04
Abstract: 1508618 Well-logging MOBIL OIL CORP 4 July 1975 [17 July 1974] 28284/75 Heading G1G The interval velocity of acoustic pulses generated by the transmitter of a borehole logging tool and travelling through the earth formation surrounding the borehole to two receivers spaced along the tool is determined by moving the tool through the borehole, producing two curves representing respectively the traveltimes T1, T2 of the pulses to the two receivers as a function of  depth in the borehole, digitizing traveltime values taken from the curves, and subtracting the digitized T1 value from the associated digitized T2 value for any given depth point along the curves. The apparatus described is the same as in Specification 1507735 with the addition of a graphical-to-digital converter and a plotter. The curves showing T 1 and T2 are obtained by photographing traces on a CRO as in that Specification. The photographic record is then placed on the table of the converter and the co-ordinates of points on the curves are digitized by moving a cursor over them. The differences #T between the T 1 and T2 values for each depth are computed automatically and divided by the distance between the receivers to obtain interval velocity values. The #T values are also plotted to give the interval velocity log shown.

Patent GB-627861-A (GB)
Title: Improvements in the production of cellulose esters of organic acids
IPC: C08B3/28
Filed: 1946-09-23
Abstract: A process for the production of stable primary organic acid esters of cellulose comprises reacting cellulose and an organic acid anhydride in the presence of an inorganic acid catalyst and of a solvent for the primary ester, neutralising the catalyst present and heating the solution of the ester while it still contains substantially no water until the ester has the required stability.  Secondary esters of improved stability may also be produced by hydrolysing the stabilized primary esters with water. The catalyst is neutralized by the addition of magnesium, zinc, aluminium, calcium, barium or strontium acetate or barium or strontium oxide or hydroxide.  Sodium salts should be avoided. The amount of water added with the neutralizing agent or that produced by neutralization should not be sufficient to hydrolyse the acid anhydride present, and if this anhydride is hydrolysed, more should be added to ensure an excess.  The stabilization is carried out by heating at from 85 DEG  to 130 DEG C. for 30 to 1 hours. After stabilization the primary ester may be precipitated as a p  soft white fibre by the addition of water, washed and dried.  In the production of stable secondary esters from the stabilized primary esters of the invention, water in amount equal to 45 to 150 per cent of the weight of the original cellulose is added and the hydrolysis conducted at a temperature of 80 DEG  to 130 DEG  C. for 100 to 2 hours or until the desired solubility characteristics or acetyl value is reached.  The ester is precipitated with water, washed and dried.  The process is applicable to the production of highly stable cellulose acetate, propionate, butyrate, and mixed esters such as cellulose acetate-propionate, and acetate-butyrate.  In an example 100 parts by weight of cotton are pretreated for 6 hours at 20 DEG  C. with sulphuric acid and acetic acid, entered into an acetyliser containing 350 parts of acetic anhydride, 400 parts of acetic acid and 15 parts of sulphuric acid (all parts by weight).  After completion of the acetylation, the sulphuric acid is neutralized by addition of magnesium acetate and the neutralized primary solution heated to 90 DEG  C. for 24 hours. The stabilized ester is precipitated with water, washed and dried.

Abstract: 1479898 Semi-conductor devices PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 28 June 1974 [3 July 1973] 28827/74 Heading H1K To eliminate spurious light output from a light emitting junction diode arising from small leakage currents &c. there is integrated with the diode in parallel with its junction a current path the current-voltage characteristic of which intersects that of the junction and the dynamic admittance of which at the intersection is less than that of the junction. In the embodiments the junction is generally of planar diffused form with the path and junction disposed at the same wafer face. The path may comprise a resistive layer, e.g. of oxide of tin or indium extending either over, or in a window, in a layer of passivation, between the ohmic electrodes to the diode regions. Alternatively it may comprise a semiconductor layer of smaller bandgap material extending from a first of the diode electrodes to form a heterojunction with the other region of the diode or to form an ohmic contact with a third metal electrode forming a Schottky barrier with the other region. Alternatively the third electrode may itself extend from the first diode electrode. In further variants the path comprises a thin diffused layer of the same type as but more heavily doped than either the diffused or the substrate region of the planar diode, bridging the junction along part of its periphery and optionally the diode contacts also where these both lie on the upper face of the substrate. In yet another variant nested heavily doped annular zones form a PN junction which is connected in parallel opposition with the diode junction by metallizations. Protection against voltage overloads by a further parallel connected PN junction of higher initial voltage is illustrated in a device the EL junction of which is formed by heavily compensated epitaxial regions.
