Title: Improvements relating to regulating arrangements comprising carbon pile regulators
IPC: H02P9/22
Filed: 1946-08-09
Abstract: 624,094. Automatic regulation. STONE & CO., Ltd., J., and NIXON, L. R. Aug. 9, 1946, No. 23633. [Class 38 (iv)] A regulating arrangement comprises a power regulator of the electromagnetic carbon-pile type having an exciting circuit connected to a controlling pilot regulator attracting a clapper type armature which acts to compress the carbon pile or piles. In Fig. 3, the pile is compressed at each end by bell-crank levers 8 connected by straps or springs 11 to a clapper frame 12 pivoted at 18<SP>1</SP>, having an armature 19 attracted by the electromagnet 20, the system being balanced about the end collectors 22 of the pile. A spring 23 connected to the armature by a strap 25 resists attraction of the armature and compression of the pile, the spring being adjusted in rate as it is bent by contact screws 26. The pivot bearings 181 are adjustable to vary the armature/pile movementratio. Testing the regulator is effected by a spring 30 connected between a toggle 34 and a pivoted bell-crank lever 32, 321 having a screw 40 (not shown) normally inoperative but arranged to abut the armature with a predetermined pressure when the spring 30 is operated by pulling out a lever 31 connected to the toggle 34 to extend the spring and release a catch 38 (Fig. 5, not shown) normally securing the arm 32. The armature consequently moves to an extent dependent on the state of the pile and is indicated by a spring-controlled pointer 33 connected to the arm 32 moving over a scale. Re-adjustment of the pile to return the indicator to a correct setting is then made by a screw 14. Stop screw 47 limits descent of the armature and jack-screw 48 locks it during transit. The pilot regulator 2 may be mounted in the frame on a swivel platform able to be swung out. Two piles side by side may be used, connected by pressure-equalizing cross-arms pivoted on the crank arms 8 acting on the piles through spiders 14<SP>1</SP> (Fig. 9, not shown). The piles may be mounted on quickrelease ceramic formers 6. ' Alternatively, a predetermined magnet excitation and test pressure may be applied to the regulator by the pilot regulator to test the armature/magnet gap. Specifications 558.621 and 575,363 are referred to.

Patent GB-336339-A (GB)
Title: Improvements in the manufacture and production of polymerisation products of diolefines
IPC: B01J19/02
Filed: 1929-08-02
Abstract: 336,339. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Aug. 2, 1929. Caoutchouc, synthetic. - The removal of the polymerization products of diolefines from the reaction vessel is facilitated by lining the vessel with a substance which does not adhere to the vessel or which may be readily removed therefrom. For example the vessel may be lined with paper, cardboard, textile fabrics, leather, sheet metal, films of cellulose derivatives or polymers of diolefines or rubber, and the diolefine polymers or rubber linings may be vulcanized or otherwise treated; or the vessel may be lined with waxes, readily fusible alloys or bitumen. It may be necessary to protect the lining by a special coating; thus in the case of montan wax, paraffin wax or bitumen which are soluble in butadiene, the lining must be coated with an insoluble substance such as nitrocellulose lacquer, a ureaformaldehyde condensation product or a film of gelatin or casein; and when a fusible alloy is used which might penetrate the polymerizate, it may be lacquered. Suitable alloys are Wood alloy (4 parts bismuth, 2 parts lead, 1 part tin, and 1 part cadmium), Newton alloy (8 parts bismuth, 5 parts lead and 3 parts tin), or Rose alloy (2 parts bismuth, 1 part lead and 1 part tin). The lining material adhering to the polymerizate may be removed in the case of paper and cardboard by water. In many cases the adherent lining need not be removed for instance if it is of a material not injurious or requiring to be added in the further treatment of the polymerizate, such as linings of diolefine polymers, asphalt, zinc oxide, carbon black, or mixtures thereof. Zinc oxide and carbon are employed with a binding agent such as gelatin or glue which is insoluble in butadiene. The polymerization may be effected in any suitable manner in undiluted, dissolved, emulsified, or gaseous state. In examples (1) butadiene is polymerized in an autoclave lined with paper, for instance a paper bag, using sodium as catalyst for 3 days at 50‹ C. (2) butadiene and dimethyl ether are treated in a rotary autoclave lined with Wood alloy coated with nitrocellulose lacquer or gelatine, with sodium wire at 50-60‹ C.; (3) butadiene is polymerized at 50-60‹ C. with sodium in an autoclave lined with bitumen coated with waterglass solution, the bitumen being finally melted; according to the purpose for which the product is to be used the bitumen may be left or is separated from the product.

Title: Improvements in or relating to methods of and apparatus for laying submarine electric cables
IPC: E02F5/14
Filed: 1937-09-03
Abstract: 503,326. Laying submarine cables. BRITISH WESTERN UNION, Ltd. Sept. 3, 1937, No. 24130. Convention date, Feb. 30. [Class 36] [Also in Group I] In a method of laying submarine cables as described in Specification 452,141, wherein the cable is installed in a trench formed in the ocean bed by a plough towed by the cable laying ship, the plough is so formed that the depth of the trench formed by it automatically varies as the ground resistance offered to the passage of the plough, the arrangement being such that a shallower trench is formed in hard ground than in soft ground, so that excessive variations in tension of the towing cable of the plough are avoided. In the construction shown, the plough comprises frameworks D, E, the latter consisting of two plates 26 connected together by transverse stays, such as 32, and provided with four skids 22 by which -the two frameworks are supported on the ocean bed. The forward skids are connected by a bridle 24a to which the towline 24 is connected. The framework D extends longitudinally of the framework E in a channel formed between plates 29 attached to the inner edges of the plates 26, the framework D being attached to the framework E by pivoted links 11 so that the framework D may move relatively to the framework E in a direction perpendicular to the plane of the plates 26. The framework D carries a ploughshare 36 for forming the trench, 'a passage 65, Fig. 4, being provided behind the ploughshare through which the cable C is led into the trench as the latter is formed. A pulley 66 disposes the cable in the bottom of the trench. The cable is guided to the passage 56 by pulleys 60, 61, 64. A plate 38 attached to the framework D lifts the ploughshare over obstructions. Springs 14, Figs. 1 and 2, connect the two frameworks and are so arranged as to urge the framework D, and the ploughshare carried thereby, downwards relatively to the framework E, downward movement being limited by members 42, Fig. 4, of the framework D engaging transverse stays 25a, 32 of the framework E. When the plough is used in soft soil the member 42 rests on the stays 25a and 32 and the ploughshare cuts a full depth trench, but when harder ground is encountered the increased resistance to the passage of the ploughshare causes the framework D to move upwardly against the tension of the springs 14, through a distance dependent upon the actual increase in ground resistance, and the ploughshare to cut a shallower trench in consequence. The springs lower the framework D when the ground resistance decreases. The towline, which is preferably formed as a chain so as to be free from torsional stresses is handled by the paying out and braking mechanism described in Specification 452,141.
