Title: Roof support assembly suitable for use in mines
Inventor: ANDREWS THOMAS DESMOND HUDSON
IPC: E21D23/16
Filed: 1964-02-14
Abstract: 1,024,167. Advancing mine roof supports. DOWTY MINING EQUIPMENT Ltd. Feb. 11, 1965 [Feb. 14, 1964], No. 6299/64. Heading F1P. In a mine roof support assembly wherein a roof support, Fig. 1 (not shown) is advanceable towards an anchorage e.g. a conveyor 3 by an hydraulic jack 2 and the roof support comprises a roof beam 10 carried on hydraulic props 5 mounted in resilient rubber bushes 7 provided in a floor skid 4, the props 5 are caused to pivot about their bushes and thus operate a control valve 13, in the event of the roof beam encountering an obstruction during advance, whereby the props are caused to lower or lower at an increased rate. The hydraulic circuit controlling the roof support, Fig. 2 (not shown) comprises a manually operated valve 14, a prop release valve 18 and a prop resetting valve 28. To advance the roof support the valve 14 is moved to a position in which a line 16 connected to the jack 2 is pressurized from a main 15. Since the props are supporting the roof, advancement does not occur until the resulting pressure builds up in the line 16 acting via a line 19 opens opens the prop release valve 18. When the props have been released a certain amount the jack 2 commences to advance the roof support and the consequent fall in pressure in the line 19 allows a spring 32 to close the prop release valve 18. If the roof beam 10 meets an obstruction the control valve 13 opens and pressure fluid from the line 16 passes via lines 21, 25 to re-open the prop release valve. When the support has fully advanced a valve 26 actuated by complete retraction of the jack 2 causes pressurisation of a line 27 to maintain the prop release valve closed and to open the prop re-setting valve 28 and thus connect the props to the main supply 15. Finally the valve 14 is returned to the position shown whereby the prop re-setting valve returns to its original position, non-return valves 31 preventing escape of fluid from the props. To advance the conveyer the valve 14 is moved to its third position to cause extension of the jack 2. In a modification, Fig. 4 (not shown), the circuit is provided with a pair of prop release valves, one of which is loaded by a weak spring to allow the props to be continually released at a slow rate when the line 19 is pressurized, the other of which is operable only in response to operation of the control valve 13 to effect an increase in the rate of release of the props. The valve 13 may also cut off the supply to the advancing jack 2 when operated and may direct fluid to the props in order to cause release thereof under power.

Title: A process for producing lubricating oils, insulating oils and similar viscous oils
Filed: 1937-03-05
Abstract: The oxidation stability of viscous synthetic hydrocarbon oils for use, e.g. as lubricants or insulating oils, is increased by adding thereto extracts obtained from natural hydrocarbon oils boiling above about 300 DEG  C., or fractions thereof, by the use of selective solvents, which extracts have been refined by selective hydrogenation.  The synthetic hydrocarbons are products obtained from unsaturated or aromatic hydrocarbons by polymerization or condensation, e.g. by the polymerization of vapour phase cracked products of paraffin wax or paraffinous materials, or by the condensation of olefines or chloroparaffins with aromatic hydrocarbons.  The polymerization or condensation may be effected either chemically in the presence of aluminium chloride, boron p fluoride or a similar agent, or by voltolization.  The extracts are obtained, preferably from a heavy mineral oil fraction, by selective solvents for constituents other than paraffins, such as liquid sulphur dioxide, nitrobenzene furfurol or cresol, and are refined to remove olefines and sulphur, nitrogen and oxygen compounds, or to render them innocuous, by selective hydrogenation.  In examples, 5 per cent of an Edeleanu extract of a lubricating oil, which extract has been refined by selective hydrogenation at a temperature of 400 DEG  C. and at an initial hydrogen pressure of 100 atmospheres in the presence of a molybdenum catalyst, is added to a synthetic lubricating oil obtained by polymerizing a vapour phase cracked gasoline, or a cracked distillate obtained from a hydrocarbon material rich in paraffin was, in the presence of aluminium chloride.

Title: Improvements in and relating to the refining of benzole
IPC: C07C7/05
Filed: 1944-04-15
Abstract: <PICT:0580124/III/1> Benzole is refined, to remove sulphur compounds and light hydrocarbons, by passing a mixture of crude benzole vapour and steam from a packed column to a reflux condenser whose uncondensed vapour outlet is maintained at a temperature of 38 DEG to 40 DEG  C., returning the reflux to the column, and withdrawing refined benzole from the base of the column.  In Fig. 1 crude benzole is fed from tank 3 to the top of packed column 1 provided at 2 with downwardly and inwardly projecting flanges; and live steam is introduced near the base of the column through pipe 5.  The vapours from the head of the column are passed to a reflux condenser 10, the uncondensed vapour outlet of which is kept at 38 DEG  to 40 DEG  C., and the condensate is returned to the column through pipe 11, while the uncondensed vapours, which comprise the impurities, are passed on to condenser 12, and removed from the system either as liquid (CS2) or gas (H2S, HCN). Refined benzole and water are withdrawn from the base of the column, the water is separated in separator 7, and the refined benzole cooled in cooler 8.  In an alternative method of operation, a mixture of crude benzole vapour and steam, obtained for example by steam treatment of benzolated stripping oil with or without fractionation of the mixture of benzole vapour and steam, is passed into the lower part of the packed column.  An auxiliary condenser may be incorporated at an intermediate point in the column; this is to reduce overloading on the condenser which is to be run at 40 DEG  C.  A thermostat may be provided, in the offtake from the reflux condenser, to control the steam supply to the base of the column if the rate of benzole input is constant, or the benzole input if the rate of steam supply is constant. Specifications 430,989 and 443,094 are referred to.
