Abstract: 637,518. Automatic regulation. HARMER, H. M. Feb. 18, 1947, No. 4679. [Class 38 (iv)] In a system for supplying a substantially constant current to a variable load R, Fig. 1, despite variation of load resistance or change in frequency of an A.C. supply Vs, the load is connected across a condenser C1 forming with a series inductance L1, having a gapped core, a circuit, substantially in resonance at the normal supply frequency, which is connected to the supply through a circuit substantially compensating for supply voltage variations. Instead of the voltage stabilizing circuit LL, Ls, Cs in which LL is a constant inductance and Ls is a saturable inductance as described in Specification 524,565, any of the voltage stabilizing arrangements of Specifications 493,362, 515,207, 521,314 and 555,004 may be substituted. In modifications: (a) the load circuit is isolated from the supply circuit by introducing a secondary winding on inductance Ls, condenser Cs then being connected across this winding; (b) the load is coupled to condenser C1 through a variable ratio saturable transformer to limit the rise of voltage across condenser C1 with high load resistance. Saturation of L1 to achieve this is also referred to; (c) the load is supplied with D.C. obtained by smoothing the output of a bridge rectifier connected to the secondary of the transformer at (b) above. An inductance inserted in series with condenser Cs to reduce harmonics and combinations of windings or cores are referred to. The Provisional Specification refers to the addition of a condenser in parallel with L1.

Title: Apparatus for laying submarine pipelines
IPC: F16L1/19
Filed: 1973-01-31
Abstract: 1414695 Laying pipelines underwater J RAY McDERMOTT & CO Inc 31 Jan 1973 [20 April 1972] 4749/73 Heading F2P In order to control the angular movement of a pipe-laying ramp 14 relatively to a ship 10, on which it is pivotally mounted about an axis 16 passing through the upper end of the pipe string, a damping means 62 is provided. The motion of a piston in cylinder 64 is damped by flow of hydraulic fluid through a restricting valve 68. Initially, a motor 74 drives a pump 72 to raise ramp 14 to an inclined position, in which the end of a pipe string 12 is held by slip elevator (18) and rubber-lined pipe clamp (20). On lifting a section 24 of pipe, by means of winch 32, a load sensor or transducer 66 closes valve 68, so that cylinder 64 and its piston rod becomes a rigid strut, while the section 24 is being joined to the pipe string 12. Crane 40 co-operates with winch 32 and arm 42 to deposite section 24 on roller way 22. To effect coupling, rollers (52, Fig. 6, not shown) are raised hydraulically above the level of rollers 22 and a conventional power tong (58) is closed around the end of the section 24, which abuts the coupling (60). After actuating tong (58), to screw section 24 into the coupling (60), the tong is released and the rollers 52 lowered. The cable 30 of winch 32 exerts a constant tension on section 24 as this slides down the roller way, after elevator (18) and clamp (20) have been released. A coating may be applied to the joint, at station (76).

Davits.-In luffing-davits of the kind in which the davit arm 3 terminates at its lower end in a toothed segmental arm 5 operated by toothed gearing and working in a casing 1 containing a lubricating liquid, the transmission gear between the hand or power-operated shaft 13 and the segmental arm 5 comprises a worm 12, supported in an end bearing 14 and a ball bearing 17, a worm wheel 11 mounted on a transverse shaft 8, which also carries a pinion 7 gearing with the segment 5. The speed at which the davit luffs may be reduced by applying the power to a second shaft 20 carrying a pinion which gears with a pinion 18 carried by the worm shaft 13. The davit arms above the point 6 about which it pivots carries an arcuate shield 29 which closes the slots in the casing in which the arm works. The casing is also provided with an extension 2<x> which accommodates the sector 5 when the davit is outboard.

Water within rubber portion 21 of inner housing 17 acoustically couples the beam into the body to be investigated through flat application surface 23 which is applied to the body. A raster scan is produced within the body by the "nodding" action of reflector 6 and carrier 1 about axis 9 in combination with the scanning action of the beam from carrier 1 across reflector 6. Fig. 2 shows how a nodded beam scans the object along lines 12, 13, and 14. The acoustic properties of the rubber hood-shaped cover 23 are chosen to closely match those of the water and the dimensions thereof are designed for minimum spurious reflection of received echo signals, while the rubber housing also absorbs the nodding movement of housing 17, e.g. at 24.

Title: Improvements in or relating to liquid phase oxidation
IPC: C07C51/265
Filed: 1950-03-02
Abstract: Alkylbenzenes are oxidized to the corresponding carboxylic acids by contacting them in the liquid phase with an oxygen-containing gas in the presence of an oxidation catalyst at 140-170 DEG  C., raising the temperature during the reaction and completing the oxidation at 180-200 DEG  C.  Various metallic oxides, hydroxides and salts are effective as catalysts, cobalt compounds being preferred.  The oxidizing gas preferably contains less than 50 per cent of oxygen. The rate of flow may be increased during the oxidation.  The reaction is facilitated by the addition of one of the products and also of the corresponding aldehyde to generate free radicals.  The mono- and polycarboxylic acids obtained may be separated by fractional distillation of the free acids, methyl esters or acid chlorides. Examples show the oxidation of p-xylene to p-toluic and terephthalic acids and of m-xylene to toluic and isophthalic acids.  The starting materials preferably have 1-4 carbon atoms in each alkyl group, other specified compounds being toluene, o-xylene, ethylbenzene, diethylbenzenes, cumene, p-cymene and propyl- and butyl-substituted benzenes.

For the down-run, steam is superheated in the upper part of the superheater before passing to the generator, a part of the mixed circulating gases being branched off and passed through the generator for withdrawal through the valve 17. Tar may be removed from the distillation gas before entering the superheater by byepassing the gas through a centrifugal blower 18, the tar collecting in a vessel 18<1>.
