Patent GB-1554614-A (GB)
Title: Wiring distribution panel
IPC: H02B1/48
Filed: 1977-04-05
Abstract: The electrical installation distributor is used for holding and phase-by-phase electrical connection of electrical installation apparatuses, especially of line protection circuit breakers (17, 18, 19), to busbars (25). On their mounting surface, the line protection circuit breakers have a U-shaped recess (27) on whose one wall a slide (28) is arranged which projects partially into the recess and is pressed into said recess in a sprung manner. Means (20) for the attachment of the busbars and, furthermore, limb parts (15, 16) of approximately L-shaped construction are fitted on one surface of a supporting panel (11). The free limb ends of these limb parts point away from the means (20) for attachment of the busbars. In consequence, the line protection circuit breakers are attached to and held on the supporting panel by means of the limb ends (16a), which engage behind the slide (28) in the assembled state, and the busbar. Blocks, for example, can be provided as means for attachment of the busbars, the busbar being attached to the end surfaces of said blocks (for single-phase operation); in the case of a multi-phase arrangement, it is possible to insert the busbars into a multi-chamber profile and to hold the insulating body by means of a tab which is bent in a U-shape. The base of a distribution box or of a housing can also be used as the supporting panel, and the busbars are held on projections of the distribution box. <IMAGE>

Abstract: 126,229. Kraus, L. P. Sept. 6, 1918. Refractory substances containing bauxite.-Relates to refractory products, either in loose granular form or in moulded kiln-burned shapes, for withstanding high furnace temperatures, and consists in reducing raw refractory material of a non- plastic character to a fine powder, mixing therewith a considerable proportion of ground combustible material such as ground wood, and water or bonding liquids such as glucose, moulding into blocks of the desired size and drying. The blocks are then roasted at a temperature sufficient to produce clinkered material in the form of spongy grains with the cleavage planes destroyed, preferably about 300 degrees F. below the melting point of the material, and above roasting or calcining temperature, and are subsequently crushed if the material is required in granular form. The invention also consists generally in the production of refractory materials having the above-mentioned characteristics. If bauxite is employed as the raw material, the resulting product can be compressed and moulded dry without bonding material and may be formed into bricks by burning in kilns at a high temperature. The roasting of the mixture may be effected in any suitable furnace, and the material may either be in cakes or loose. Fluxes may be added, if desired, and if binders are employed in moulding the material, any ceramic bond such as plastic clay may be chosen.

Patent GB-670956-A (GB)
Title: Improvements in or relating to the catalytic synthesis of hydrocarbons
IPC: C07C1/04
Filed: 1948-06-04
Abstract: <PICT:0670956/IV (b)/1> Hydrocarbons of high molecular weight are produced by contacting mixtures containing CO and H2 with a dense, turbulent mass of finely-divided iron catalyst, the oxygen content of which is positively maintained between 10 and 30 per cent based on pure iron in accordance with the desired molecular weight of the product, and in any case at a figure greater than that which would be obtained if the oxygen content of the catalyst were permitted to attain equilibrium under the prevailing synthesis conditions. Unreduced catalyst, which is substantially Fe3O4 or Fe2O3 with an oxygen content of 38-43 per cent based on pure iron, gives highest yields of wax and other high molecular weight products but wax deposition causes agglomeration of catalyst particles.  Fresh unreduced catalyst may be added to the reactor containing reduced or partly reduced catalyst in an amount of 2-10 per cent of catalyst inventory per day, depending upon the product desired.  Any desired volume of catalyst and carbon concentration thereon, such as 15-25 per cent by weight of the reduced catalyst, may be maintained by withdrawal of used catalyst from the upper part of the bed and addition of unreduced catalyst. Examples illustrate the effect of additions in raising the pour-point of a product oil from - 60 to +55 DEG  F.  Alternatively, periodic hydrogenation or oxidation of the catalyst in situ or in a separate reactor may be used.  Thus, the synthesis gas may be replaced by air, CO2, steam, oxygen, hydrogen or a gas richer or poorer in hydrogen.  Oxidation with steam or steam-air containing 1-10 per cent oxygen may be effected at 500-750 DEG  F., 0.750 p.s.i.g. and velocities of 0.3-1.5 ft./sec.  For hydrogenation, temperature may be 650-1100 DEG  F.  A curve is given show-ing the correlation of wax formation with oxygen content for catalysts consisting of fused magnetite promoted with potassia and alumina and reduced in hydrogen or reduced and precarbided in a H2-CO mixture, and sintered pyrites ash resintered in air with coke and potassium carbonate, and reduced.  A reactor 10 containing a fluidized catalyst of 1-500 m , preferably 20-30 per cent 0-20 m  and 30-40 per cent 80+ m , of density 30-150 lbs./c.ft., initially added from hopper 20, is fed with unreduced catalyst from hopper 24 while catalyst is withdrawn through line 26, oxidized in vessel 38, and returned through line 46 suspended in fresh or spent synthesis gas supplied through line 44.  Instead of adding unreduced catalyst, oxidizing gas may periodically be admitted through line 12.  Vessel 38 may alternatively be used as a reducing zone.
