Abstract: 1304485 Battery charging systems INSTITUT FRANCAIS DU PETROLE DES CARBURANTS ET LUBRIFIANTS 19 April 1971 [4 March 1970] 22947/71 Heading H2H A circuit arrangement for storing electrical power required to operate a member 8 such as a valve in a remote, submerged well-head comprises a main accumulator 3 charged indirectly from an electric generator 1 and a protective circuit which interrupts the charge current for the accumulator when fault conditions arise. The generator, which may be a fuel cell, is connected via a current regulator 19 adapted to detect a short circuit, an open circuit detector 20, a current measuring device 21 and switches 4a-4c to Nickel-Cadmium auxiliary accumulators 2a-2c, A programme device 27  controlled by a clock 25 closes the switches 4a-4c in sequence to enable the generator to charge the auxiliary accumulators which are discharged in sequence by the successive closing of switches 5a-5c under the control of the clock 25. The discharge currents flow through current regulator 22-24 and a current detector 28 to charge the main accumulator 3. When a transmitter-receiver 9 receives an ultrasonic command signal from a central station requesting operation of the member 8 an actuation device 17 receives a signal from the transmitter-receiver and causes closure of a switch 12 to open the valve at the well head or closure of a switch 14 to close the valve. If the device 21 detects that the charging current for the auxiliary accumulators is outside predetermined limits a signal is supplied on line 31 to a safety device 32 which causes the device 17 to close the switch 14 and maintain the valve closed. The device 32 also sends a signal on line 34 to the clock 25 which opens the switches 5a-5c and causes the device 27 to open the switches 4a-4c. If a low charging current is detected by the detector 28, a signal on line 36 causes the device 27 to open the switch 4a-4c associated with the faulty auxiliary accumulator and a new programme is initiated using only the remaining auxiliary accumulators. Failure of all the auxiliary accumulators causes the device 27 to supply a signal on line 39 to the safety device 32 which causes the device 17 to close the switch 14 thereby holding the valve closed. Detectors 41 monitoring pressures and temperatures at the well head also cause closure of the valve when these parameters exceed predetermined values.

Title: Improvements in the production of resin coated abrasive grain for abrasive articles
IPC: C08L61/10
Filed: 1935-08-16
Abstract: 461,437. Resin - coated abrasive. TENNANT, W. J. (Carborundum Co.) Aug. 16, 1935, No. 23104. [Class 60] In preparing resin-coated grains for use in the manufacture of bonded abrasive articles such as wheels and stones, and coated articles such as sandpaper, flexible discs and belts, a mix of abrasive grains coated with pulverized resin and a plasticizing agent is aged in an atmosphere of which the aqueous vapour pressure is less than the vapour pressure of the mix. Absorption of aqueous vapour by the mix, and the consequent tendency for the mix to become sticky and to cake, are thereby avoided. The mix is spread into a layer preferably about one or two inches deep and may be turned or stirred during the ageing to avoid caking of the lower part of the layer. The temperature at which the ageing is performed is preferably as high as possible in order to shorten the time, but is limited by the nature of the mix. Mixes plasticized with furfural, for example, tend to cake if the temperature exceeds 80‹ F., whilst those in which a liquid resin plasticizer is used may be aged at 108‹ F. Examples are given of mixes employing alumina abrasive grains, pulverized " A stage " phenol-formaldehyde resin, and a liquid phenol-formaldehyde resin or furfural as plasticizers, together with the conditions of temperature, hygrometric state of the atmosphere, and time under which the ageing process is carried out. In the case of a certain mix employing a furfural plasticizer the aqueous vapour pressure of the atmosphere is reduced to 9 mm. of mercury by the employment of a dehydrating agent and by circulation of the air in the ageing chamber by a fan, the temperature being 74‹ F. In an example of a mix having a liquid resin plasticizer the ageing is carried out at 85‹ F., the aqueous vapour pressure being 16 mm. of mercury. The method may be applied to heat-hardenable resins, such as phenolic condensation products or certain alkyd resins, or to permanently fusible resins such as novolaks, meta-styrene, and thermo-plastic alkyd resins, or to mixtures of resins, such as a phenolic liquid resin and a dry alkyd resin or powdered shellac.

Patent GB-658458-A (GB)
Title: Improvements in or relating to the recovery of fatty acids from dilute aqueous solutions
Filed: 1949-09-12
Abstract: <PICT:0658458/IV (b)/1> Fatty acids are recovered from dilute aqueous solutions by adding a bismuth compound to the solution to form the bismuth salts of the fatty acids, separating these salts from the solution and regenerating the fatty acids from them.  The method may be applied to the recovery of a mixture of fatty acids or to solutions containing only one acid.  The mixture of fatty acids may be the mixture obtained during hydrocarbon synthesis reactions between hydrogen and oxides of carbon in the presence of a catalyst. The solution containing the acids is treated with a bismuth compound, preferably an oxide of bismuth or a mixture of bismuth compounds. The bismuth salts so precipitated may be coagulated by the addition of an electrolyte, e.g. sodium sulphate, sodium chloride or sodium phosphate.  The fatty acids are regenerated from their salts by various methods, e.g. by heating the salts with steam, sulphuric acid or sulphur trioxide.  If steam is used, barium oxide, which can be reused in the process is obtained.  If sulphuric acid or sulphur trioxide is used bismuth sulphate is formed, and this may be roasted to give bismuth oxide.  In the Figure the aqueous feed containing fatty acids is led to the lower portion of reactor 2 containing bismuth oxide.  The point of entry of the feed is lower than the upper level of the bismuth oxide.  A colloidal suspension of the bismuth fatty acid salts is obtained and overflows from the upper part of reactor 2.  Unreacted acids, colloidal bismuth fatty acid salts and water enter another bismuth oxide reactor 6.  A series of bismuth oxide reactors may be used or only one as desired.  The colloidal suspension of bismuth fatty acid salts overflows from the upper portion of reactor 6 into settler 12.  An electrolyte solution, e.g. sodium sulphate, is added and coagulates the fatty acid salts, causing them to settle.  The settling tank effluent, if desired, may be sent through zeolite or other ion exchange materials to enable the small amount of bismuth therein to be recovered.  A thickened slurry of bismuth fatty acid salts is withdrawn from the lower portion of the settler 12.  If the acids are to be regenerated by steam the slurry is reduced by suitable means, e.g. by air drying, filtering or centrifuging.  If sulphuric acid is used for regenerating the water content should be reduced only in accord with the desired water content of the product.  In the latter case the aqueous slurry is pumped to reactor 17 where it is treated with sulphuric acid.  The temperature in the reactor is conveniently maintained in the range 104-163 DEG  C.  In the example a dilute solution of acetic acid was contacted with bismuth oxide and the bismuth salt obtained was treated with sulphuric acid to give acetic acid and bismuth sulphate.

Abstract: 839,099. Maintaining vehicle height constant. BENDIX-WESTINGHOUSE AUTOMOTIVE AIR BRAKE CO. July 22, 1958 [Sept. 13, 1957], No. 23532/58. Class 108(2) An automatic levelling valve for a pneumatic vehicle suspension system incorporates an additional valve which increases the rate of flow of air to and from the springs when, for example, a door is opened or a manual control is operated. The levelling valve comprises a spring- loaded disc 36 which is lifted off its seat 40, to admit air from pipe 22 to a chamber 56 communicating with the air spring (not shown) through a port 94, by upward movement of a valve stem 46 which is moved by a roller 60 eccentrically mounted on a spindle 62 which is rotated by a linkage (not shown) in response to movement of the vehicle body relative to the associated axle. Stem 46 has a bore 70 which, when the stem is fully lowered, connects the chamber 56 to atmosphere through a groove 52, a gap between the end of the stem and cylinder wall 48, a filter 78 and exhaust port 74, thereby exhausting air from the spring. In the position shown the spring is connected to neither the pipe 22 nor the port 74, since disc 36 is seated whilst bore 70 is closed by abutment of the stem 46 with the disc. Inserted between the chamber 56 and port 94 is a perforated valve member 84 which, in the position shown, restricts the flow of air to and from the spring, but which is opened to increase the rate of flow when a piston 106 is operated by energization of a solenoid valve 122 consequent upon opening a door of the vehicle or by other means. Piston 106 is returned to its raised position on de-energization of valve 122 by the pressure in the spring which is transmitted to chamber 110 through a duct 112 and chamber 56. The-perforation in valve member 84 contains a loosely fitting wire 98 which, in addition to increasing the resistance to flow, maintains the perforation free from obstruction.
