Title: Counting and registering apparatus with automatic zero-setting device
IPC: G06M1/30
Filed: 1963-04-17
Abstract: 976,058. Counting-apparatus. KIENZIE APPARATE G.m.b.H. April 17, 1963 [April 21, 1962], No. 15049/63. Heading G4D. All the wheels of a counter, especially in a fuel dispersing pump, are simultaneously set to zero on the heat cam principle, transfer pinions being disconnected meanwhile, the two actions being effected by separate slides connected to a common control element. With the registers in zero condition removal of the nozzle (not shown) from its holder operates link mechanism to close a switch controlling the pump. Initial operation of the pump rotates wheel 46 closewise, Fig. 7, so that cam 42 rotates through 350 degrees before being held against further rotation, a light friction coupling 51 (Fig. 8, not shown) preventing return motion of the cam until the end of zero-setting. The cam 42 rocks zero-setting segment 5 clockwise to the position shown in Fig. 1, so tensioning spring 10. Zero-setting takes place when the nozzle is pushed home and through a linkage (Fig. 13, not shown) rocks pawl 130 to withdraw blocking lever 15. Zero-setting segment 5 then returns under spring action, driving disc 7 through 180 degrees by means of a one-way pawl and pinion mechanism 16, 8, the speed being controlled by a flywheel 102. Disc 7 has two cams causing two slides 24, 25 to make an up-and-down movement. The slide 24 shifts shaft 33, Fig. 4b, to the left to disconnect the transfer mechanism by disengaging pinions 37 from one of each pair of stepping pinions 35<SP>1</SP>, 35<SP>11</SP>. Slide 25 then disconnects the input drives to all four registers by rocking arm 74, Fig. 10, to disconnect toothed couplings 64, 65. Slide 25 also strikes levers 29, Fig. 4a, against heart-shaped cams to return all numeral wheels to zero. Slide 24 returns before 25 to re-connect the transfer mechanism before the drive. To guard against failure in the automatic tensioning of spring 10 by the pump mechanism a crank may be connected at 6 to effect resetting. Full-stroke mechanism is provided to ensure full restoration to zero.
Patent GB-801827-A (GB)
Title: Preparation of oil-soluble metal naphthenates
Inventor: LES TADEUSZ LEON
Filed: 1956-05-15
Abstract: Oil-soluble magnesium naphthenates are obtained by contacting a hydrocarbon oil containing naphthenic acids with an aqueous caustic solution, and further reacting said caustic solution after separating from the oil, with an aqueous solution of a water-soluble salt of magnesium at not more than 15 DEG  C., whereby a precipitate of an oil-soluble magnesium naphthenate is formed, and separating said precipitate from the supernatant liquid.  The caustic solution is preferably diluted, e.g. with a hydroxyl ion concentration less than 0.6 gm. ions/litre.  Specified magnesium salts are the chloride, nitrate and sulphate, or sea-water may be used.  In a modification, a hydrocarbon oil containing naphthenic acids is contacted jointly with a caustic solution and a solution of a water-soluble salt of magnesium, whereby the magnesium naphthenate formed is dissolved directly in the hydrocarbon oil. In an example, a spent caustic solution from a petroleum refining process is contacted with a magnesium chloride solution.

Title: Pulsed neutron well logging methods
IPC: G01V5/10
Filed: 1975-04-14
Abstract: 1500946 Neutron well-logging TEXACO DEVELOPMENT CORP 14 April 1975 [6 May 1974] 15166/75 Heading G1A A well-logging method comprises: passing through a borehole a logging tool having a pulsed fast-neutron source and a detector longitudinally spaced therefrom; repetitively irradiating the surrounding earth formations with bursts of neutrons; generating first and second signals responsive to detected gamma radiations attributable respectively to neutron capture by hydrogen during a first interval, and to neutron capture by hydrogen or another element during a second interval, following the neutron bursts; and recording a resultant signal obtained by combining the first and second signals. A logging tool 7 Fig. 1 contains a deuteriumtritium source 11 modulated by a pulsing circuit 14 to emit 1 ms bursts of 14-MeV neutrons at 10 ms intervals, the circuit 14 being driven by a pulser 20 activated by a time reference 39 at the surface. A photo-multiplier 10 coupled to a NaI(Tl) scintillator 12 shielded from the source 11 provides pulses each having an amplitude proportional to the energy of a received gamma ray, and applies them, via a discriminator 18 to remove background radiation below 0À5 MeV, to a linear amplifier 17, whence the pulses are transmitted up a cable 8 to a spectrum stabilizer 44 and thence to three gates 40, 41, 42. The gates, enabled in turn by the time reference 39, admit pulses to a pulse height analyzer 45 monitored and corrected by the stabilizer 44. If the neutron burst from the source 11 ends at time 1À0 ms, then outputs from the analyzer 45 are provided in response to the three gated inputs as follows:- (a) Gate 40: interval 1À1-2À0 ms: (i) signal H1 of pulse count in energy range 1À3-2À9 MeV attributable to neutron capture by hydrogen. (ii) signal Cl of pulse count in the range 3À4-8À0 MeV due to chlorine. (b) Gate 41: interval 1À4-2À0 ms: signal H2 due to hydrogen (energy range as for H1). (c) Gate 42: interval 4À0-9À8 ms: signal 0 of pulse count due to oxygen in the range 3À0-7À25 MeV. The signals are processed as follows:- (d) In a computer 47 the intrinsic neutron lifetime #, characteristic of the exponential decay of neutrons due to surrounding earth formations, is calculated from the H1 and H2 signals detected during the overlapping first and second intervals. (e) In a computer 52 the chlorine signal Cl is fed through, and a signal Cl(H) representing a relationship between the Cl and H1 counts is generated. A chlorine count which is unexpectedly low in relation to the H1 count may indicate the presence of hydrocarbon on fresh water, as distinct from salt water. (f) A computer 53 generates a signal representing the ratio of hydrogen to oxygen which, if high, indicates hydrocarbon rather than water. The output signals generated by the computers 47, 52 and 53 are displayed as a function of logging tool depth by a recorder 48.

Abstract: 196,510. Tussaud, G. P. June 7, 1922. Moulds; preparing surfaces; treating after electrolysis.-Articles from which metal replicas are to be made by electrolysis are dipped in liquid made by mixing 1 lb. of phosphorus dissolved in 15 lbs. carbon bisulphide, 1. lb. camauba or other wax dissolved in 1 lb. turpentine, 2 oz. caoutchouc dissolved in a little carbon bisulphide, and 1 lb of asphalt dissolved in just enough carbon bisulphide to be liquid. The phosphorus solution may be replaced by 1 lb. of metol dissolved in 10-20 lbs. of toluene. The articles, after drying, are then dipped in a solution of 1/3 oz. of silver nitrate in 1 gallon of water or alcohol. After drying they are then coated electrolytically with copper, silver, gold, bronze or other metal. When the articles are of a delicate nature, such as flowers, leaves. lace or the like, they are stiffened before subjection to the above treatment by dipping in a French polish consisting of about 2 oz. of shellac dissolved in a pint of methylated spirit and drying. After plating, the articles are heated to redness thereby volatilizing the phosphorus. if present, and quenched in water or oil: oil renders copper articles tougher but less pliable.
