Filed: 1928-01-06
Abstract: 283,483. British Thomson-Houston Co., Ltd., (Assignees of Alexander. P. P.). Jan. 10, 1927, [Convention date]. Uniting by fusion.- Electricarc welding is performed with a metallic-electrode of low carbon content in the presence of a hydrocarbon which will dissociate in the arc to provide a protective atmosphere of hydrogen together with the liberation of free carbon, which supplies the carbon necessary to impart to the weld characteristics similar to those of the parent metal and which causes the production of non-porous welds by preventing chilling of the surface of the crater and thus ensuring the escape of gases dissolved during welding. Examples of such hydrocarbons are propane and natural gas. To vary the amount of carbon deposited the propane may be mixed with hydrogen, carbon dioxide or nitrogen. Examples consist of 85 per cent of hydrogen and 15 per cent ofpropane, and 95 per cent of nitrogen and 5 per cent of propane. The gases may be contained in cylinders 10, 11 provided with valves 13, 14 communicating through a valved pipe 9 with a hood 8 of asbestos or metal covered with asbestos, in which the plates 4, 5 to be welded are placed. Welding is performed by a hand electrode 1.- Welding may also be performed semi-automatically as described in Specification 184,141 or wholly automatically. Other elements may be introduced into the weld by using a composite electrode or by placing alloying metals on the seam. Specifications 245,090, 257,955, and 272,067 are referred to.

Patent GB-827374-A (GB)
Title: New organo-metallic compounds and methods for their production
IPC: C07C45/50
Filed: 1956-03-06
Abstract: The invention comprises compounds of formula [(C5H5)X(CO)3]nY, in which X represents chromium, tungsten or molybdenum, Y represents hydrogen, a metal cation or a complex cation and n is equal to the valency of Y. They may be prepared by reacting an alkali metal cyclopentadienyl with chromium, tungsten or molybdenum hexacarbonyl and, if desired, reacting the resultant organo-alkali metal compound with an acid, a water-soluble salt of a metal or of a complex cation. The reaction is preferably carried out in an inert solvent such as dioxane, dimethyl formamide, ethylene glycol monomethyl or monoethyl ether, in the absence of atmospheric oxygen.  Aqueous solutions of the alkali metal salts yield in the absence of air the hydrides on acidification with a strong acid such as acetic, hydrochloric, sulphuric, phosphoric, paratoluene sulphonic or trichloracetic. Metal salts, e.g. of copper, lead, thallium, cadmium, mercury and salts of complex cations such as the dicyclopentadienyl cobaltic cation may also be prepared.  On standing in vacuo, the hydrides reversibly split off hydrogen to give dimers of formula [(C5H5)X(CO)3]2.  O standing in air the hydrides lose water to give the dimers.  In the examples the following are prepared: (1) cyclopentadienyl chromium bicarbonyl hydride and (2) the mercuric salt thereof; (3) the dicyclopentadienyl cobaltic salt thereof [Co(C5H5)2]+[(C5H5)Cr (CO)3] -; (4) and (5) the dimeric [(C5H5)Cr(CO)3]2; (7) cyclopentadienyl molybdenum tricarbonyl hydride; (8) cyclopentadienyl tungsten tricarbonyl hydride; and (9) the thallium, lead, cadmium, copper, dicyclopentadienyl cobaltic and trisphenanthroline nickel salts thereof.

Title: Improvements in or relating to the manufacture of glass phials, bottles and like artiles
IPC: C03B23/09
Filed: 1939-01-09
Abstract: 524,927. Glass manufacture. JOHNSEN & JORGENSEN FLINT GLASS, Ltd., and ASHFORD, E. Jan. 9, 1939, No. 707. [Class 56] A method of shaping the end of a glass tube or the mouth of a phial consists in inserting a plug into the tube while the glass is in a plastic state, then expanding the plug to form a recess or recesses in the glass, and finally contracting and withdrawing the plug, the operations being performed mechanically. The plug comprises two jaws 7, 8 pivoted together at their forward ends and provided with arms 10, 11, respectively which project through slots in a sleeve 38. Springs 22 connect the arms and keep the jaws closed against the spreading-action of a conical portion 27 on the end of a rod 26 that slides through the sleeve 38. The device is actuated by a block 36 which slides along a bar 39 and is reciprocated by a cam. A spring 46 surrounds the rod 26 between the end of the sleeve 38 and an adjustable collar 43, and a stronger spring 45 is interposed between the collar 43 and a bush 44 that screws on to the block 36. The rear end of the sleeve 38 screws into a sliding block 46<SP>1</SP> and carries a plate 48 having a bifurcated end 49 that embraces the bush 44 between the head 42 and a nut 50. In operation, a glass tube or phial with a softened end is placed on rotating rollers and is urged against an adjustable stop, and the plug mechanism moves along the rod 39 until a stop 51 in the sleeve 38 is arrested by a bracket 40. The spring 46 is compressed and the rod 26 continues to move and spread the jaws, and projections 53 on the jaws groove or indent the softened glass, the spring 45 being compressed when the spreading movement of the jaws stops. On the reverse movement of the blocks 36, the nut 50 makes contact with the fork 49 and allows the springs 22 to close the jaws. Continued movement of the block withdraws the plug from the end of the glass tube. The plug may be rotatable in its holder and allowed to rotate with the glass tube to enable any desired type of indentation, for example, of the bayonet type, to be produced. Specification 519,553, [Group XVII], is referred to.
