Patent GB-389858-A (GB)
Title: Improvements relating to grab buckets
IPC: B66C3/12
Filed: 1931-09-25
Abstract: 389,858. Grab-buckets. PRIESTMAN, S. H., Holderness Foundry, Hull, and PRINCE, S., Hillcrest, Swanland Road, Hessle, Yorkshire. Sept. 25, 1931, No. 26801. [Classes 78 (ii) and 78 (iv).] The angular position of a grab is controlled from a distant point by weighted ropes attached to opposite sides of the grab, one rope being hauled in while the other is payed out by means under the control of the operator. As shown in Fig. 1, the ropes 20, 22 are led round sheaves on a beam 28 and over sheaves 34 to the weight 36. The beam is turned about a vertical axis by a hand-lever 32 to slue the grab, and the weight 36 keeps the ropes taut as the grab is raised or lowered. As shown in Fig. 3, each rope 20 or 22 passes round a sheave 24, then round a sheave 26 on a lever 38 pivoted on the roof of the crane cab, and thence over sheaves 34 to the weight 36 which slides on a guide 56. The two levers 38 are connected by links to opposite ends of a lever 42 pivoted at 44 and operated in either direction by a hand-lever 48 and a pawl controlled by the hand grip. In a modification, Fig. 4 (not shown), this gear is operated by a hand-lever forming a downward extension of one of the levers 38. As shown in Fig. 5, the gear is mounted on the jib ; each rope 20 or 22 passes round sheaves at 24, 26, 24, 34 to the weight 36 sliding on a guide 62, and the levers 38 are operated by the hand-lever 48 through the lever 42 pivoted at 44. Another method of hauling in and paying out the ropes 20, 22 is shown in Fig. 6. The ropes pass over sheaves 24 free on a shaft 68, round sheaves 64 on the weight and in opposite directions round sheaves 66 to which they are secured. The sheaves 66 are fixed on the shaft 68, and on turning this shaft, one rope is hauled in and the other payed out to slue the grab. In a modification, Figs. 7-9 (not shown), this gear is mounted on the crane jib and operated by a hand-lever and pawl. For slueing a grab operating in the hold of a vessel, the ropes 20, 22 are led over sheaves near the jib head and are connected with the grab by the device shown in plan in Fig. 11. The two ropes are attached at 86 to a pulley 78 secured to the grab head, and are led over sheaves 82 on a triangular frame 80 pivoted freely on the grab head. When one rope is hauled in and the other payed out, the frame 80 tends to maintain the same position relatively to the jib, so that the pulley 78 is turned and the grab is slued. In order to slue the grab by power the shaft 44, Figs. 3 and 5, or 68, Fig. 6, is provided with a drum, operated by ropes 88, Fig. 12, from a drum 92 which is driven by reversible ratchet gearing. A crank pin 104 is driven constantly in one direction and oscillates a lever 98 about the pivot 100. The lever 98 carries pawls 96, either of which is brought into engagement with a ratchet wheel 94 on the drum 92 by a spring 114 on moving a lever 116 in one or other direction. The drum 92 is checked by a friction brake or is connected with the ratchet wheel through irreversible worm gearing.
Patent GB-691684-A (GB)
Title: Improvements relating to the separation of paraffinic hydrocarbons
IPC: C10G73/06
Filed: 1949-10-19
Abstract: Crude paraffin wax is separated into two paraffinic fractions having different melting points by treating it at a temperature above 0 DEG C in a water-cooled vessel with a mixture of solvent (selected from benzene and toluene) and non-solvent (selected from methanol, ethanol and butanol), the mixture containing at least sufficient non-solvent to render it azeotropic, so that only the lower melting point paraffin hydrocarbons are dissolved and separating the solution from the undissolved paraffin hydrocarbons.  According to a modification of the process, the crude paraffin wax is completely dissolved in the mixture of solvent and non-solvent and the solution is then cooled to a temperature above 0 DEG C so that only the higher melting point paraffin hydrocarbons are precipitated.  This cooling may be carried out stepwise, thereby producing a plurality of paraffinic fractions. The separation of the solution mentioned above or the separation of the precipitate may be carried out in a centrifuge and the solid paraffins remaining may be washed with fresh mixture of solvent and non-solvent.  The mixture of solvent and non-solvent may be distilled from both solids and solution for reuse.  In an example, slack wax is treated in a water-cooled vessel with a 70-30 by volume mixture of ethyl alcohol and benzene at 54 DEG F.  The mixture is centrifuged and the solids washed with fresh ethyl alcohol-benzene mixture by distillation, steamblown and bleached with Fuller's earth.  The refined wax has a melting point of 131-135 DEG F.  The liquid phase from the centrifuge is freed of the ethyl alcohol-benzene mixture by distillation, thus leaving an oil of pour point about 50 DEG F.  The Specification as open to inspection under Sect. 91 refers to the paraffin wax being dissolved in the solvent, followed by the addition of the non-solvent to precipitate the desired fraction. If desired the addition of non-solvent may be effected step-wise, while the addition of non-solvent may be accompanied by cooling. This subject-matter does not appear in the Specification as accepted.

Title: A process for arsenising organic compounds
IPC: C07F9/70
Filed: 1926-11-05
Abstract: 261,026. Scheller, E. Nov. 9, 1925, [Convention date]. Arsinic acids are prepared by reacting upon carbocyclic or heterocyclic diazo compounds with arsenic halides in the substantial absence of water, and decomposing the products with water or dilute acid. The diazotization may be carried out in the presence of a restricted amount of water, whilst catalysts, such as copper and its compounds, may be present. The production of the diazo compound from the corresponding amino compound, in which either amyl or sodium nitrite is employed as diazotizing agent, may be carried out in presence of the arsenic halide. According to the examples, (1) a mixture of a-oxy-#<1>- aminopyridine hydrochloride, glacial acetic acid, arsenic trichloride, and a little cuprous chloride, is heated with a strong sodium nitrite solution; after distilling off the solvent under reduced pressure, the residue is precipitated as the arseno compound with sodium hydrosulphite and then dissolved in hydrogen peroxide to give a-oxy-#<1>- pyridine-arsinic acid, which is separated and purified; p-nitrophenylarsinic acid is obtained in a similar manner from p-nitraniline; (2) p-aminoacetophenone is dissolved in methyl alcohol. arsenic trichloride, concentrated sulphuric acid, and a trace of cuprous chloride then added, and the mixture diazotized with sodium nitrite; by further treatment as in the preceding example, p-acetophenone-arsinic acid is obtained.

Title: Process for making boron steel
Filed: 1953-10-09
Abstract: Molten steel containing a normal nitrogen content is separated from its furnacing slag and is treated in a separate vessel with a slag comprising a borating agent such as borate from the group alkali metal borates, alkaline earth metal borates and boric oxide to which is added a reducing agent such as aluminium and at the same time the steel is flushed with a non-oxidising, nitrogen-free inert gas to eliminate nitrogen, thereby causing boron to enter the steel without interference by boron nitride.  The borate containing slag may have the composition: .CaO.-.50-60 per cent .Al2O3.-.10-20 per cent .CaF2.-.10-15 per cent .borax.-.5-10 per cent .TiO2 and ZrO2.-.10-20 per cent The amount of this slag added is preferably 1-6 per cent by weight of the metal.  The inert gas may be supplied, continuously or intermittently, till the boron content of the steel is 0,001-0,005 per cent and the nitrogen content is reduced to less than 0,005 per cent by weight.  Aluminium is used to deoxidise the steel before treatment and, to protect the boron against oxidation the treated steel should contain a residual aluminium content not less than 0,02 per cent.  Specifications 671,678 and 697,915 are referred to.
