Title: Improved tool-carrying tractor boom apparatus
IPC: E02F3/96
Filed: 1955-11-08
Abstract: 817,647. Earth-moving apparatus; shovelling machines. MID-WESTERN INDUSTRIES Inc. Nov. 8, 1955 [Nov. 8, 1954; Nov. 18, 1954], No. 31859/55. Class 68(1) A tool-carrying broom has telescopic arms 10 within which are disposed fluid actuated, double-acting jacks 15 for extending and contracting the parts 11, 12 of the arms and to the parts 12 are attached at 35 link members 16. The parts 11 are pivotally mounted at 13 to a frame 19 which can be secured to a tractor and the link members connected at 32 to brackets 17 on the frame. The length of the link members is such that they become tensioned immediately the arms are extended from a fully retracted position and then cause upward pivotal movement of the arms as the arms are further extended. The link members 16 can be chains or rods having lost motion connection with the parts 12 of the arms 10. The tool may be a grader blade or a shovel. When the frame 19 is secured to the tractor the axis 13 is so positioned with respect to axis of the traction wheels 8A that when the arms 10 are fully retracted so that the link members 16 are slack and the tool engages the ground the line of reactive thrust from the tool to the axis 13 passes below the axis of the traction wheels.

Title: Improvements in or relating to a process and apparatus for making carbon black
IPC: C09C1/50
Filed: 1946-10-29
Abstract: <PICT:0633945/III/1> Carbon black is made by admitting a relatively large body of air divided into several separate parallel streams into an elongated unrestricted combustion space, injecting into the combustion space a multiplicity of small jets of carbon-containing gas, e.g. natural gas, arranged in rows between adjacent air streams, flowing the jets of gas in the same direction as the air streams and passing the gas directly and in well distributed manner into the air at such higher velocity than that of the air as to establish a localized turbulent mixture about the jets under conditions of incomplete combustion thereby decomposing unconsumed gas while in free space and collecting carbon particles from the combustion products.  The shell of rectangular steel furnace 10 with refractory lining 13 converges to outlet 12 and has alternate refractory piers 14 and burner boxes 15 (see Group XI).  Air is directed through diaphragms 18 from inlets 16 and issues between the parallel burner tubes 20 while natural gas is fed as a multiplicity of parallel or divergent high velocity jets from orifices in the front walls of burner tubes 20 causing localized turbulence wherein combustion takes place with carbon black-formation as the swirling flame progresses towards the outlet 12.

Title: Improved process of briquetting finely divided fuels and apparatus therefor
IPC: C10L5/22
Filed: 1934-11-08
Abstract: A dispersion of water in oil is prepared for the briquetting of fuel by mixing a petroleum or coal tar oil with a solution of an organic colloid in the presence of a small quantity of a soluble alkaline material; a saturated solution of an easily soluble salt is added with agitation and the mixture combined with finely divided fuel and a bituminous binding agent, the mass being mixed, heated and briquetted.  Or the oil, colloid, water, and saturated solution may be mixed at atmospheric temperature and added to a large mass of the finished dispersion maintained in agitation at 90--99 DEG  C., from which a supply is pumped and sprayed over the bituminous binder mixed or not with fuel.  The bituminous binder may consist of pitch made from tar with sulphuric acid or as described in Specification 397,484, or of petroleum asphalt, the oil employed being creosote or tar oil in the one case and a petroleum oil, such as crude paraffin gas oil, Diesel oil, &c. in the other.  The colloid may be obtained from cereals, casein, glue, sulphite cellulose liquor &c. and the alkaline material may be sodium silicate syrup.  Examples of easily soluble salts employed comprise the chloride, chlorate, or nitrate of ammonium, alkali, or alkaline earth metal, or the sulphate of ammonium or alkali metal.  In an example: the dispersion is made up of waste lubricating oil, 30 parts, flour sweepings, 7\ba1/2\be parts, sodium silicate \ba1/2\be part, ammonium nitrate 2 parts, and water 60 parts, 1,5 parts of the dispersion being incorporated in 94,8 parts of washed anthracite duff and 3,7 parts of petroleum asphalt.

Tyres, elastic, and tyre covers, tools for removing and replacing.-A forked lever 1, Fig. 1, each prong of which has a spoon-shaped end and a depression on the underside to engage the rim beading, is inserted under the tyre beading and a further bite obtained by placing a single-pronged lever between the prongs of the lever 1 which may then be withdrawn and inserted elsewhere. A single-pronged lever for the same purpose is similar to the lever 1, but is formed with a screw-driver point. In a modification a lever 12, Fig. 7, has one end spoonshaped and slightly spatulated and formed with a depression for engaging the rim beading, the opposite end having a hooked member 17 to engage the rim beading and a square-edged member 18 to engage the tyre and force the beading clear of the rim. If the leverage is insufficient a member 19 is inserted between the member 18 and the tyre, the square edged member 18 riding upon the flat body of the member 19 between side fillets. A hook 24 on the member 19 engages the rim. In mounting a tyre the member 19 serves to pin one portion of the tyre to the rim while the tyre is forced on to the rim by the levers.
