Title: Leak detector for pressure and vacuum systems
IPC: G08B13/16
Filed: 1962-10-18
Abstract: 990, 080. Detecting ultrasonic vibrations. DELCON CORPORATION. Oct. 18, 1962 [Nov. 14, 1961], No. 39441/62. Heading G4F. [Also in Division H4] In a method for detecting leaks in a pressure or vacuum system an ultrasonic transducer is disposed in the vicinity of the system to pick up ultrasonic vibrations emitted by a leak and to generate an electrical signal corresponding to the vibration. This signal is mixed with a further signal which differs from it in frequency by about 3, 000-5, 000 c/s so that a beat signal having a frequency of approximately 3, 000-5, 000 c/s is generated. The beat signal is supplied to a sonic transducer which generates an audible sound corresponding to the beat signal, to indicate the presence of a leak in the pressure or vacuum system. In one embodiment (Fig. 1) the ultrasonic vibrations are detected by means of a transducer 10 which converts them into an electric signal which differs from it in frequency by about 14. The signal then passes through a high pass filter 16, which rejects substantially all frequencies below 15, 000 c/s and then to a mixer 18. The mixer is also supplied from an oscillator 19 which is tuned so that the mixer produces a difference signal in the 3, 000-5, 000 c/s range. The mixer output passes through a low pass filter 20 to an audio amplifier 22 and thence to a push-pull audio output stage terminating in a loudspeaker 26, where an audible tone is produced. In many cases e.g. in a noisy environment, or for checking such as telephone lines enclosed in pressurised conduits, it is desirable to separate the listening and pick up portions of the system, and the apparatus of Fig. 2 may be used. In this system the electrical signal produced by the ultrasonic transducer is used to modulate the output from a crystal controlled high frequency oscillator 40 (producing a signal in the frequency range 2-10 Mc/s). These modulated signals are transmitted from an antenna 44 to a receiving antenna 46. The receiver consists of a conventional single sideband, carrier suppressed receiver 48, designed to receive the lower sideband, and is connected to a loudspeaker 50. This receiver contains an oscillator driven at a frequency just above the lower sideband frequency, so that when the transmitted signal is mixed with the receiver oscillator output, a signal in the audible range is detected.

Title: Turbine drive well pump
IPC: F04D3/00
Filed: 1974-09-10
Abstract: 1448167 Turbine driven well pumps; hydraulic turbines KOBE Inc 10 Sept 1974 39501/74 Headings F1C and FIT A pump 16 suitable for oil wells comprises a turbine 30 which drives an axial-flow pump 32 via a shaft 34, means being provided to minimize the axial forces acting upon the shaft resulting from pressure differences between the well fluid and the turbine power fluid. Power fluid passes to the turbine via tube 12, passages 39, 40, 41, 42, 43, ports 57 and inlet 36, the fluid exhausting via outlet 38 and passages 45, 46, 23 and 20. Pump 32 draws fluid through inlet 48 and conveys it to the surface via outlets 50, ports 52 and passages 54, 56, 24 and 22. Pump discharge pressure is exerted downwardly on a surface 62, Fig.3, via passages 74 and annular space 72. The power fluid-pressure acts upwardly on a surface 64 via passages 43, 82, 80, 76. The areas of surfaces 62, 64 are such the resultant force acting on the shaft 34 balances the force due to the unequal pressures at its ends 84, 86. The pump 16 is slidable within tube 12, and may be removed by blocking tube 20 and passing pressurized fluid down tube 22.

Title: Polymeric lubricating oil additives
IPC: C08G79/02
Filed: 1963-10-09
Abstract: A lubricating composition consists essentially of a blend of a major proportion of a mineral or synthetic lubricating base oil and a minor proportion of an oil-soluble metal salt of a phosphosulphurized polymer which is produced by reacting a polymer of 4-methyl pentene-1, having a limiting viscosity number within the range 0.1 to 1.5, that has been prepared by polymerizing the monomer at a temperature within the range 50 DEG  to - 120 DEG  C. in the presence of a Friedel-Crafts catalyst, with a phosphorus sulphide, hydrolysing the phosphoro-sulphurized polymer so formed, and neutralizing the acidic hydrolysed product with a hydroxide, oxide, or alkaline reacting salt of an alkaline-earth metal, or aluminium.  In an example, 4-methyl pentene-1 is polymerized in n-heptane solution with AlCl3 as the catalyst, and the formed polymer, after precipitation and drying, is heated with P2S5 under nitrogen, a light refined mineral lubricating oil is added, the mixture is refluxed with a mixture of water and phenol and then iso-octane is added and the resulting mixture allowed to settle.  The aqueous and phenol layers are removed and the polymer/oil mixture is dissolved in n-heptane and refluxed with Ba(OH)2.  The phosphosulphurized polymer salt is blended with a light refined mineral lubricating oil and is found to have a high shear stability and a high detergent activity.ALSO:An oil-soluble metal salt of a phosphosulphurized polymer is produced by reacting a polymer of 4-methyl pentene-1, having a limiting viscosity number within the range 0.1 to 1.5, that has been prepared by polymerizing the monomer at a temperature within the range 50 DEG  to -120 DEG  C. in the presence of a Friedel-Crafts catalyst, with a phosphorus sulphide, hydrolysing the phosphoro-sulphurized polymer so formed, and neutralizing the acidic hydrolysed product with a hydroxide, oxide, or alkaline reacting salt of an alkaline-earth metal, alkali metal, or aluminium.

Title: Pressure-rupturable microscopic fluid-containing capsules
IPC: B01J13/10
Filed: 1957-12-23
Abstract: Pressure-rupturable microscopic capsules containing a fluid in which is dispersed particles of magnetic material, e.g. black or red magnetic oxide, carbonyl iron, ferrous magnetic alloys, nickel and its magnetic alloys may be used in the form of a suspension for coating a sheet to make record material for printing by magnetic means.  The magnetic materials may be permanently magnetized in the capsules or they may be magnetized by magnetic field applied to the capsules.  They are suspended in an oily vehicle, e.g. chlorinated diphenyl or petroleum fractions of low boiling-point.  As much as 50% by volume of the magnetic powder, as compared with the oil, may be included within the capsule. Methods of making the capsules and applying them to sheets of paper are described in Specifications 751,600 and 759,800, where formation of the colloidal surface of the drops round the metal-oil suspension by coacervation is described.  A colouring material may be added to the oil to increase the coloration of the droplets.  As described, 30 parts of magnetic iron oxide are suspended in 160 parts trichlordiphenyl containing 1 part oleic acid, 0.1 gs. zinc stearate and 1 part dioctyl-phthalate until the average agglomerate size of the oxide particles is about 3 microns.  The suspension is emulsified first into a gelatine-water solution (isoelectric point of pH8) at a pH of 6.5, and then into a gum arabic-water solution also at pH 6.5.  The mixture is diluted with water and its pH is adjusted to 4.7 to bring about coacervation with deposit of the colloid material round the oil droplets.  A 37% solution of formaldehyde is added to the mixture and the temperature is lowered to produce gelling of the gelatine and then a 5% solution of a copolymer of polyvinyl methyl ether and maleic anhydride is added with stirring to prevent the capsules from agglomerating in the subsequent hardening step which is effected by adjusting the pH of the mixture with NaOH to 9-10 so that the formaldehyde reacts with the colloid to harden it. The dispersion thus obtained can be coated directly onto paper and dried or the water may be removed by spray drying and a fine powder obtained consisting of the discrete capsules containing the magnetic material floating in the included vehicle.

Abstract: 851,546. Pigmented paper containing synthetic resins. IMPERIAL CHEMICAL INDUSTRIES Ltd. Dec. 12, 1958 [Dec. 23, 1957], No. 39870/57. Class 96. Pigments, e.g. azo pigments, phthalocyanine pigments, inorganic chrome and iron lakes, phospho-molybdic and phosphomolybdotungstic lakes of basic dyestuffs, or carbon black, are incorporated during the manufacture of paper in conjunction with a condensation product obtained by heating, in the absence of water, a polyalkylene polyamine with cyanamide, a derivative thereof, or a derivative of cyanocyanamide. The condensation product is preferably added to pulp slurry in the beater after the pigment has been added. The polyalkylene polyamines specified are diethylene triamine, triethylene tetramine, tetraethylene pentamine, bis - (# - aminohexyl)amine, 1: 2 - bis - (w - amino-hexyl amino)ethane, or a polymer of ethylene imine. Specified derivatives of cyanamide and cyanocyanamide are phenyl cyanamide, guanidine, dicyandiamide, phenyldicyandiamide, p - chlorophenyl - dicyandiamide, hexamethylene - bis - dicyandiamide, ethylenebis - dicyandiamide, guanylurea, biguanide, phenylbiguanide, or salts with weak acids of guanidine, guanyl urea, or biguanide. The condensation products, which should be employed in the form of their acid salts and may be used in conjunction with salts of copper, iron, cobalt, nickel, chromium, or zinc, are prepared by heating the ingredients together at a temperature of 70-200‹ C., optionally in the presence of an organic diluent as described in Specifications 522,539, 657,753 755,519, and 798,061; amounts of 2.5 to 25% of the weight of the pigment are suitable and may completely replace aluminium sulphate. According to an example, 20 parts of a 20% paste of copper phthalocyanine were mixed in a beater with 100 parts of air-dry, bleached α-cellulose pulp. 1 part of the condensation product of ethylenebis-dicyandiamide and diethylene triamine dissolved in water and acidified with dilute acetic acid was mixed in. A sheet of paper produced from this furnish was very much stronger in depth of shade than a sheet produced by use of an equal weight of aluminium sulphate instead of the condensation product.

Abstract: 950,185. Traffic control systems. WESTING- HOUSE BRAKE & SIGNAL CO. Ltd. Nov. 16, 1960 [Nov. 27, 1959], No. 40411/59. Heading B7N. In the event of an emergency or for maintenance purposes, the rail traffic through a track network normally controlled from a central office is controlled from a local panel comprising control changeover means and manual control means for each element in the network and the same all-electric interlocking arrangements are used for both types of control. The local area, Fig. 1, comprises signal 1 and points 5, 6 controlling routes 1(1), 1(2) and 1(3). The local panel includes a control changeover switch by which a relay LZR (not shown) is switched to its normal position when local control is taken, three position switches for points 5, 6 each of which must be in a central position when local control is taken and which also control associated points control relays 5WLR and 6WLR (not shown) to their normal and reverse positions and a signal switch, which, when operated to its reverse position to clear signal 1, energizes a relay RR (not shown). Assuming route 1(1) has to be set up from the local panel, points control relays 5WLR and 6WLR are switched to their normal and reverse positions respectively and the signal switch is set to reverse. A route locking relay 1(1) RLR, Fig. 4, is reversed via normal and reverse contacts of relays 5WLR and 6WLR, a front contact of relay RR and a normal contact of relay LZR. Signal 1HR, Fig. 6, is then cleared via normal contacts of points control relay 5WLR and points detection relay 5KR, reverse contacts of points control relay 6WLR and points detection relay 6KR, a reverse contact of route locking relay 1(1) LR, a front contact of relay RR and a normal contact of relay LZR. When controlled from the central office the front contact of relay RR and the normal contact of relay LZR, forming part of the above traced circuits, are shunted by the front contact of a relay which is energized when the control is remote and a reverse contact of relay LZR.

Six insulated double guide members 1a..1f (three shown) are normally earthed by strip 4 and are connected to RC members 13a..f and thence to amplifier 5 so that its inverting input is zero volts and this is negative relative to the voltage at the non-inverting input developed by voltage divider 6 which is lower than that of relay 12. If one of members 1a..1f is lifted, however, a positive voltage will be applied to the input of amplifier 5. The time taken for the signal to arrive at amplifier 5 will depend on the dimensions of the corresponding RC member. A null voltage signal will be delivered to input 8a of NAND gate 8. If there is excessive tension on strip 4, it engages and earths contact 3 to apply zero volts to input 8c of NAND gate 8. The inputs of the NAND gate are normally served with a positive voltage so that, when zero volts are applied, a positive voltage will appear at output 8 which through NOR gate 11 operates relay 12 to stop the machine.
