Abstract: 711,524. Endless belt conveyers. CABLE BELT, Ltd. March 23, 1953 [April 22, 1952]. No. 10124/52. Class 78 (1) In a belt conveyer of the kind in which the belt is supported and driven by two endless cables, one on each side of the belt, transversely extending resilient metal rods are embedded in the belt at intervals and cable engaging means are provided within the width of the belt and within the span of the rods. As shown in Figs. 1, 5, the belt is supported by cables 11, 12 passing over pulleys mounted on stands 13, alternate stands supporting two pairs of pulleys 14, 15 for the upper and lower cable runs, whilst the intermediate stands support a single pair 14 for the upper run only. The belt comprises thick and thin layers 23, 24 of hard wearing resilient material, the layer 23 having embedded in it a reinforcement 25 of textile material such as duck. Between the layers are spring steel straps 26, the spaces between the straps being filled with a material 27 of a similar nature to that of the layers 23, 24 but of an inferior quality. On each surface of the belt at a position opposite a strap 26 pairs of lugs 16, 17 integral with the belt provide notches 18 for the cables 11, 12. A rib 19 is also moulded on each side of the belt. In a modification Fig. 8 (not shown), the straps are replaced by round bars and the cable-engaging means are formed by longitudinal ribs or ridges on the belt. Specifications 641,817 and 703,891 are referred to.

The 51-alkoxycarbonyl compounds may be hydrolysed with an alcoholic solution of an inorganic base to the corresponding 51-carboxy compounds, and these or the esters may be reduced with lithium aluminium hydride to the 51-hydroxymethyl compounds, which may be converted to their tosylates and these refluxed with lithium aluminium hydride in pyridine to give the 51-methyl compounds.  Any acyl groups present at R4 or R5 may be removed by treating with sodium methoxide in methanol at room temperature, while acyl groups at R4 may be selectively removed with aqueous acetic acid.  9a -Halo-11b -ols may be oxidized to the 11-ones before pyrazole-ring formation and subsequently reduced.  21-Ols and N-unsubstituted compounds may be acylated, and 21-ols may be converted to 21-halo and 21-unsubstituted compounds by standard procedures, N-unsubstituted compounds being protected as the N-carbamoyl derivatives.  The pyrazolo-steroids of the invention, which are stated to have high anti-inflammatory activity, may be made up into pharmaceutical compositions with suitable carriers.

IPC: F15B15/06
Filed: 1963-03-14
Abstract: 1,007,502. Change-speed control; connecting rods. EATON AXLES Ltd. Feb. 27, 1964 [March 14, 1963], No. 10217/63. Headings F2D and F2T. A two-speed vehicle axle has a shift lever extending through its casing and joined by a torsion spring to a biasing lever 1 pivoted to the connecting rod 3 of a piston 5, a strong spring 11 biasing the piston to one of its two extreme positions, corresponding to establishment of one or other ratio in the axle. On the admission of pressure fluid, e.g. compressed air from the vehicle brake system, through a port 7, the piston 5 is forced downwards against the bias of the spring 11 to twist the torsion spring; when torque loading on the axle is later reduced, the torsion spring effects the desired ratio shift. When the port 7 is vented to exhaust, the strong spring 11 twists the torsion spring in the opposite direction preparatory to re-establishment of the other ratio, again effected when torque loading on the axle is reduced. The spring 11 engages a thimble 9 surrounding and bearing against the connecting rod 3, in turn engaging at its end with a nylon &c. wear pad 16. The other end of the spring 11 lies in a connector retained in a surrounding housing 6 by a spring circlip 14, removal of which allows dismantlement of the piston &c. assembly.

The push-buttons 5, 6 press inwards a plate 8 mounted in a rod member 9, which moves axially in the sleeve portion 16 of a drum 37 by virtue of axial and coinciding grooves 10, 11, 12, 13 which together form housings for the balls 15, 14. Two spiral ballgrooves 21, 22, 23 of substantially V-section are provided in member 9 and co-operate with balls 19, 20 and a V-section circular track in member 17, rotation of which consequent on axial movement of member 9 is transferred through slots 35 and pin 36 to the tuning condenser spindle 33. A ball thrust-bearing 25 is provided and a spring 30 opposes the tuning movement, thus taking-up play and restoring the spindle to its initial position when the button is released. For manual tuning, knob 39 operates drum 37 through a cord drive the members 16, 9. 17, 33 then rotating together. Axial movement of member 16 is prevented by a fixed stud 41 engaging a circular groove in the member.

Title: Process for recovering sulphuric acid from iron sulphate
IPC: C01B17/74
Filed: 1963-03-15
Abstract: Sulphuric acid is prepared by roasting iron sulphate at 500-800 DEG C., cooling the resultant gases containing water vapour and sulphur trioxide with free oxygen-containing gases to 350-550 DEG  C., contacting them with the iron oxide formed during roasting to oxidize SO2 to SO3, and then condensing the resulting gases.  The iron sulphate may be entirely or partially dehydrated prior to the roasting at 120-300 DEG  C. (e.g. to the monohydrate). In the figure, iron sulphate crystals from hydro extractor 1 pass into directly heated rotating tubular oven 2, into dehydration zone 3, reactor zone 4, then into contact zone 6 where the products of roasting meat a free oxygen containing gas from lance 7, where the iron oxide formed catalyses the oxidation of SO2 to SO3.  Progress between zones is assisted by worn-type sluices.  Solids and gases pass out through slits in an outlet drum at the end of the oven, the solids pass through gas trap 9 and gases pass via pump 5 to condensation absorbtion tower 15.  To supplement the catalytic effect of the iron oxide, the gases from over 2 may be led, via heat exchanger 11 to maintain them at 400-450 DEG  C., and fine filter <PICT:1020386/C1/1> 12 to contact oven 13, where remaining SO3 is oxidized using a water vapour insensitive catalyst e.g. vanadium-potassium-silicate, and then to condenser/absorber 15. Shelved ovens or vortex charged ovens may replace the tubular oven, heating of the gas being effected outside the oven between roasting and the contact stage.

Title: Method for the control of the refining by a stream of oxygen of carbon-containing metal melts
IPC: C21C5/30
Filed: 1963-03-18
Abstract: In a process of refining iron by top-blowing with a stream of oxygen or oxygen-enriched air the exhaust gases are completely burnt, as by allowing air to enter the hood, and the products monitored.  From the total amount of carbon dioxide in the gas the amount of carbon eliminated from the bath is calculated, while from the proportion of evolved carbon monoxide which is burnt in the hood, as derived from the content of nitrogen entrained there, there may be calculated the amount of carbon monoxide burnt in the furnace and hence under standard conditions the temperature of the bath. These results are used to control the additions of oxygen and coolant so that the desired bath temperatures are attained. In a two stage process, the additions are used to produce the desired intermediate composition, at which stage a sample is analysed and the result used to correct the additions during the second stage of blowing.  Control may be effected by a computer which is fed initially with data relating to the charge and the desired, and continuously with that relating to the exhaust gases. Specifications 759,224, 843,714 and 941,485 are referred to.
