Patent GB-965416-A (GB)
Title: Process for preparing trialkyl aluminium compounds
IPC: C07F5/06
Filed: 1960-10-12
Abstract: Trialkyl aluminium compounds are prepared by passing a liquid containing a dialkyl aluminium hydride downwardly through a reactor column provided with internal obstructions in contact with a gaseous olefin which is caused to flow upwardly through the reactor, a gaseous phase being discharged above the outlet for the liquid phase. By discharging the gas phase at or near the top of the reactor less than 10% of the gas discharged consists of the olefin. The downflowing liquid takes up the amount of olefin necessary for the formation of the trialkyl aluminium compound and in addition some of the olefin dissolves in the liquid. On passing the liquid phase to a zone of reduced pressure the dissolved (unreacted) olefin is liberated and may be recycled. If desired the olefin may be diluted with a gas inert to the reaction, e.g. hydrogen. Specifications 770,707 and 836,792 are referred to.

Patent GB-391532-A (GB)
Title: Process and apparatus for the thermal decomposition of hydrocarbons
IPC: C01B3/22
Filed: 1931-12-22
Abstract: In a process for the thermal decomposition of methane or a gas containing it by passage through heated refractory material, whereby carbon, hydrogen and small amounts of hydrocarbons other than methane are produced, the heat of the cracked products is utilized by injecting into the gas stream at one or more points further quantities of the gas to be treated.  In the apparatus shown, a vertical <PICT:0391532/III/1> converter 1 filled with refractory material is heated by burners 2 supplied with hydrocarbon fuel by a valved pipe 3 and with air from a blower 7 by a manifold 6.  Leading from a lower part of the converter is a stack pipe 8 provided with a valve 9, and from the valved top of the converter is a pipe 17 through which the cracked products are withdrawn.  Steam and hydrocarbons are admitted to the stack pipe by valved pipes 10, 12 respectively.  Valved pipes 15, 23, 24 are provided to admit further supplies of hydrocarbons to the top of the converter and to the pipe 17.  The lower end of the pipe 17 is closed, a pipe 27 leading therefrom into a wash box 20 where the carbon produced is trapped, the gaseous products leaving by a pipe 21.  In operation, the valve 14 being closed and the stack valve 9 open, the refractory material is heated by combustion of the hydrocarbons from the pipe 3, the hot gases passing downwards through the converter and up the stack pipe. When the desired temperature is attained, the valve 9 is closed and the hydrocarbon gas to be cracked is injected into the stack by the pipe 12, cracking commencing in the stack and being completed in the converter.  Further gas to be cracked by the hot reaction gases may be injected by the pipes 15, 23, 24.  After the temperature of the converter has reached the lower limit, the supply of material is cut off, the valve 14 opened and the contents of the converter removed by steam injected by the pipe 10, after which the converter is reheated. An example is given of the treatment of natural gas containing principally methane and ethane in the proportion of 83 to 17; the refractory material is heated to 1100 DEG  C. and the gas resulting therefrom contains small amounts of acetylene, ethylene, carbon dioxide and nitrogen, together with 11,6 per cent of carbon monoxide, 72,7 of hydrogen and 12,7 of methane.  After treatment with supplementary gas, the main gaseous content is 10 per cent of carbon monoxide, 67,4 of hydrogen and 18,1 of methane.

Abstract: 1461118 Photo-electric testing of optical systems D L GUYTON 12 Aug 1974 35514/74 Heading G1A [Also in Division G2] A method of determining the astigmatic error of an optical system 20 comprises aligning the principal meridians of optical correcting means 40 having both cylindrical and spherical variable dioptric power, with those 22, 24 of the system 20, correcting the dioptric power error in a single chosen meridian of the system by adjusting the means 40, and varying the dioptric power of the means 40 other than in the chosen meridian, preferably in a meridian at 45 degrees to the principal meridians, by a zonal focus test until the astigmatic error in the combination 20, 40 is zero. The error introduced by the means 40 equals the error to be determined in the system 20. The zonal focus test may involve a small number of zones of the system 20 (Scheiner principle) or all the zones, and the means 40 may comprise movable lenses, e.g. cylindrical lenses moveable relative to each other, or fixed lenses and a moveable target. The target may be an opaque line 14 on a transparent disc 28 which comprises two halves of polarizing material oriented at right angles, and zone-defining means may comprise a Scheiner disc 32, i.e. an opaque disc having two or more apertures 34 carrying polarizing material aligned with the material 28. Fig. 3A shows the arrangement after the first two steps of the method have been carried out, and Fig. 3B (not shown) after varying the dioptric power of the means 40 in the meridian 22, the image halves 54 being then aligned. In a modification, Figs. 4A, B (not shown) the line 14 is replaced by a slit (16) in an opaque disc (30) and apertures 34 by slits (36) which lie between the source 26 and the target (16), (an astigmatic array target) and Fig. 7 (not shown) illustrates diagrammatically an apparatus which selectively employs the Scheiner principle or the astigmatic array target. The screen 18 on which the image 54 is formed may be a photo-electric device.

Abstract: 361,127. Testing balance of rotary apparatus. DUNLOP RUBBER CO., Ltd., 32, Osnaburgh Street, London, and WILLSHAW, H., of Dunlop Rubber Co., Fort Dunlop, Erdington, Birmingham. Nov. 28, 1930, No. 35788. [Class 106 (ii).] A tyre is tested for balance by mounting it on a support rotatable about a horizontal axis to which the support is secured by movement of an outer annular surface by fluid pressure to engage and centre the tyre, the support being then rotated and allowed to come to rest under gravity. A wheel 1 preferably made from a light-weight metal or alloy is mounted by means of ball bearings 2, 3 on a horizontal shaft 4 secured to a stand 10. The wheel comprises a boss portion 13 united by radial webs 14 with a ring portion 15 provided with a ring of holes 16 any one of which may be filled by insertion of a known balancing weight. The outer part of the wheel extends by means of a web 18 to an overhanging channelled surface 19 upon which is seated an inflation tube 20 to which air is admitted through a valve and elbow joint 21. The tube is retained by a flange 22 bolted to the portion 19. Upon the tube 20 floats a rim 23 divided at a plurality of points into a number of segments in order that the latter may be expanded to enable the supporting pressure on the tyre beads to be equalized and the tyre thus properly centred about axis of the wheel. The rim segments are guided between the flange 22 and a ring 25 of angle section secured to a flange 26 on the web 18 and engaging into a groove 28 cut in the sections. The groove is preferably filled with. an elastic band which when the air bag is collapsed contracts the rim and facilitates removal of the tyre. In use a tyre cover is placed over the collapsed segmental rim and air or other dry gas admitted to expand the rim when the tap is turned off and air supply disconnected. The wheel is given a slight rotary movement and allowed to settle. As soon as the wheel is at rest, a mark is made at the highest point of the tyre this being opposite the heaviest point. Vanes 17 attached to the rear of the wheel work within a fixed casing 12 and damp the movements of the wheel. A weight corresponding to the valve to be used with that tyre is then placed in the hole nearest the mark. The wheel is then rotated through 90‹ and the weight adjusted to balance.
