Title: Improvements in pivotal couplings
Inventor: RIGNALL NORMAN ROBERT
IPC: B60M1/20
Filed: 1961-01-05
Abstract: 929,144. Supporting cables. BRITISH INSULATED CALLENDERS CABLES Ltd. Jan. 4, 1962 [Jan. 5, 1961], No. 518/61. Class 36. [Also in Group XXV] A pivotal coupling comprises a hook and an eye in which the surface of one opposite to its surface against which the other bears when the coupling is under tension is concave is provided a bearing surface for the latter when the coupling is under compression. As described, Fig. 1 (not shown), a horizontal strut 2, comprising insulating part 10 and metallic part 9, is connected at the insulating end to a mast 6 by means of a coupling 11 according to the invention, its other end engaging a bracket 7, Fig. 1 (not shown), attached to the conducting end of a similar inclined strut I carrying an overhead wire; the lower insulating end 5 of the strut being fixed to the mast by means of a universal pivot 14. The coupling 11 comprises a horizontal eye 23 of nearly triangular form and a hook 15 the material of both being of circular cross-section. The hook 15, engaged vertically in the eye 23 at its apex, incorporates a rectangular pad 18, of which the surface opposite to the apex of the eye is doubly concave and nearly flush with the inner surface of the hook, the curvature of this surface being less than that of the apex of the eye both in the horizontal and vertical plane, so that when the coupling is under compression the apex of the eye bears against the pad and can rock and roll freely on that surface. Unhindered rocking and rolling of the coupling is achieved also when the coupling is under tension by making the curvature of the hook longer than the inner curvature of the apex of the eye in the horizontal plane and the curvature of the apex layer than the inner curvature of the hook in the vertical plane, at the region where the two bear against each other. The apex of the eye is maintained in the same vertical axis as the lower pivot 24 so that the stable equilibrium position of the hook with respect to the eye is always at the apex of the eye.

Title: Improvements in and apparatus for the manufacture and production of carbon black
IPC: C09C1/54
Filed: 1929-01-09
Abstract: 326,913. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges. Jan. 9, 1929. Carbon.-The catalytic decomposition of carbon compounds to produce carbon black is carried out by subjecting such compounds to heat treatment in a non-sparking electric field in which no substantial discharge takes place. The carbon compounds include acetylenes, olefines, diolefines, also paraffin, aromatic; and hydroaromatic hydrocarbons, carbon monoxide, or mixtures of these substances. The process may be carried out in the presence of other gases or vapours such as water vapour, nitrogen peroxide, carbon dioxide, nitrogen, or hydrogen. As catalysts, the metals of the iron group or their compounds are particularly suitable, and their activity may be increased by the addition of activating suhstances, in particular oxides, hydroxides or carbonates of sodium, potassium, boron, magnesium, barium, strontium, calcium, cadmium, zinc, aluminium, magnesium, vanadium, chromium, titanium or thorium, or the said metals themselves, or phosphorus pentoxide. The catalysts may be employed on carriers such as pumice, fireclay, silica gel, charcoal, magnesia, fuller's earth, and the like, or the charged electrodes, which may be constructed of metals of the iron group, may themselves serve as catalysts. Both continuous and alternating current may be used, and the current is of a very small magnitude, for example 1 milliampere or less. Examples are given in which carbon black is produced from (1) ethylene, (2) a mixture of allylene and water vapour and nitrogen, (3) a mixture of carbon monoxide, water vapour and nitrogen and (4) propylene. One form of construction of apparatus is shown in Fig. 1 in which A is the catalyst, retained in position by a wire cage B electrically connected with the tube C, which is heated by means of an electrical heating device D; tube C serves as the positive electrode and is insulated from the heating device by the mass F. The positive electrode B is arranged within the counter electrode G and is insulated therefrom by means of the stopper H. Voltages up to 200 volts or more may be applied to the electrodes, and the reaction is most conveniently carried out at temperatures ranging from 300‹ to 500‹C,
