IPC: G01N17/02
Filed: 1970-06-09
Abstract: 1,263,219. Measuring corrosion rates. PETROLITE CORP. June 9, 1970, No.27996/70. Heading G1N. A corrosion rate meter of the type having three identical electrodes of the same material (e.g. mild steel) as the structure being monitored in which the current passed between one pair of the electrodes to produce a given polarization potential between another pair of the electrodes is measured, is provided with automatically operating nulling circuitry to compensate for the effects of the freely corroding potential and the resistive losses in the leads. In Fig.2, the electrodes are connected to terminals R, T and A. A sequencer connects in turn each of a plurality of testing stations and a meter prover to the circuit of Fig. 2. When a particular station is so connected, switches 67, 71, 89, 112 are first set to their "null" positions. The freely corroding potential plus IR lead potentials at R and T are connected to an isolation amplifier 36, the output of which is combined at 86 with a reference signal (which may be positive or negative) representing the polarization potential to be established between the electrodes connected to R and T and fed back via circuit 66 to input 38 of the isolation amplifier 36 to develop at equilibrium a corrective potential across resistor 47 equal to the algebraic sum of said freely corroding potential, IR lead potentials and polarization potential. At equilibrium the recorder displays the freely corroding potential. The switches 67, 71, 89, 112 are then changed over to their "operate" positions. Capacitor 81 stores a function of the corrective signal to maintain the potential across resistor 47. A current is caused to flow between the electrodes connected to A and T, the circuit reaching equilibrium when the said polarization potential has been established between the electrodes connected to R and T. The current through A and T is measured and indicated on meter 106. During this operation, the IR potentials at R and T remain unchanged. The "null" and "operate" sequence may be carried out twice, using the alternative positions of switches 87, 94, 118 to provide anodic and cathodic polarization potentials respectively. Adjustments. Potentiometer 41 is set to give zero output from the amplifier 36 when no electrodes are connected to the terminals. Switch 133 enables high or low gain to be selected in the "null" feedback circuit. Resistors 69, 134 and switch 136 enable range selection for the current between A and T. Meter prover. This is a resistance network which simulates a known corrosion rate when it is connected to the circuit of Fig. 2, by the sequencer. If all is well, the recorder indicates during the "operating" phase the current between A and T appropriate to this known corrosion rate.

Title: Improvements in or relating to pipe couplings
IPC: F16L51/00
Filed: 1925-11-10
Abstract: 242,987. Siemens - Schuckertwerke Ges. Nov. 11, 1924, [Convention date]. Joints with packing operated by fluid pressure; hinge and swivelling joints.-Relates to couplings for pipes laid in a flexible manner of the type wherein the axial movement of the ends of the pipes to be coupled together which takes place when the piping is exposed to pressure is utilized for compressing a packing body. In the form shown in Fig. 1, a packing-ring 4 is positioned against a flange 12 on the pipe 2 by a cap 5 which is secured to the end of the pipe 1 by bayonet catches 6, and when the piping is exposed to pressure the pipe ends 1, 2 will tend to separate and compress the packing 4 so that it assumes the form and position shown in dotted lines. By a suitably compact construction the packing-ring could be compressed somewhat during the coupling when the pressure is non-existent. Alternatively, each pipe end is provided with a flange 12 and a packing-ring 4, the whole joint being enclosed and adjusted by an external sleeve. In Fig. 3 the invention is applied to swivelling pipes 1, 2, the packing ring 4 being held in place by a ring 5 which co-operates with turned-over projections 6 on the end of the pipe 1 to form a bayonet joint. The Specification as open to inspection under Sect. 91 (3) (a) describes an alleged modification wherein a hose-like packing 34, Fig. 4 (Cancelled), overlaps the pipe ends 1, 2 and is surrounded by a netting 35 which is connected to rings 26 secured to the pipe ends by bayonet pins 6. When the piping is exposed to pressure, the two ends will separate and thus reduce the cross-section of the netting, which will consequently press the packing 34 against the pipe ends. This subjectmatter does not appear in the Specification as accepted.

Title: Process for the production of chlorinated dicarboxylic acids
IPC: C07C51/41
Filed: 1959-08-19
Abstract: A dicarboxylic acid HOOC-A-COOH, where A is a straight or branched chain aliphatic hydrocarbon radical or a cycloaliphatic hydrocarbon radical, is chlorinated with chlorine in a liquid medium resistant to chlorination (especially CCl4), while irradiating with actinic light or at elevated temperature in the presence of a radical promoting agent, e.g. iodine or a Friedel-Crafts catalyst.  Examples chlorinate (1) nonadecane dicarboxylic acid, (2) tetradecyl glutaric acid, (3) tricyclodecane-(5. 2. 1. 02,6)-dicarboxylic acid-(4,8), and (4)-(8) a mixture of C19 a -alkyl dicarboxylic acids obtained by hydroformylation of oleic acid, hydrogenation and alkali fusion. Other types of suitable acid are listed, including terpane dicarboxylic acids.  The chlorinated acids form salts with inorganic and organic bases; the alkali metal salts are surface-active agents and as aqueous solutions are of use for cleaning metal surfaces. Copper, zinc and aluminium salts may be precipitated by treating an aqueous solution of the alkali metal salt with an aqueous solution of a salt of the corresponding metal; this may be effected on a fibre to impregnate the latter, and the active centres presented by the chlorine atoms used by further chemical reaction to improve, alter or dye the fibre.  Materials such as paper impregnated with acids or their metal salts are rendered less inflammable.  The acids may also be used in the preparation of insecticides, fungicides and bactericides.

Filed: 1937-10-19
Abstract: 509,695. Road signals for controlling traffic; valve relays. SIEMENS & GENERAL ELECTRIC RAILWAY SIGNAL CO., Ltd., and RIDDLE, H. J. N. Oct. 19, 1937, No. 28440. [Class 118 (ii)] [Also in Group XL] In an electrical tuning device in which a time delay is determined by the time taken for a condenser to charge or discharge to a value at which a discharge device strikes, the device is maintained in a state of oscillation by an auxiliary condenser so that the voltage across the device is not in excess of the striking voltage when the timer is set in operation. As applied to a speed timer of the type described in Specification 408,706, the difference between the supply voltage and the normal voltage across condenser QA is arranged to be considerably in excess of the striking voltage of neon tube N. With the timer inoperative (as shown), the tube periodically strikes, due to auxiliary condenser QAW and resistance YCN. Contact rw reverses, upon a vehicle passing in the road having the right-of-way, to prevent the timer operating if, immediately thereafter, a demand is entered from the cross street, causing contact de to close to complete the timer circuit. As the voltage across tube N can never be in excess of its striking voltage, and owing to the relatively large available voltage, the timer is substantially independent of supply voltage variations and changes in tube characteristics.
