Abstract: 1,251,572. Heating and cooling pulverulent materials; drying pulverulent material. F. L. SMIDTH & CO. A/S. 2 Sept., 1970 [2 Sept., 1969], No. 43349/69. Headings F4B, F4G and F4U. Pulverulent material is heated or cooled or dried whilst passing down a shaft 1 in counterflow to upflowing gases. In one form, the refractory lined shaft is provided with at least one helical rib 15, which is preferably uninterrupted and of constant pitch, and which has an upper surface that slopes downwardly by between 0 and 70 degrees. Baffles 17 extend at least partly between adjacent turns of the rib, to stop the upflowing gases, which pass through a central " free space " comprising between 25 and 50% of the cross-sectional area of the shaft, from taking a helical flow path. Where, as shown, the baffles only partly extend between adjacent turns of the rib, which in this case has a pitch of about 40 degrees, the descending material gets trapped in gas eddies which form at the upper edge surfaces of the rib and travel down along it to the bottom of the shaft whilst the material undergoes extensive heat exchange within the eddies. Alternatively when the baffles fully extend between adjacent turns of the rib, stationary eddies are formed, the material falling from one eddy to another as each upper eddy becomes saturated with material. In a modification (Fig. 5, not shown) a central gas return pipe or solid core is located within the shaft, the " free space " being defined in the annulus between the pipe or core and the shaft. The helical rib(s) may alternatively be formed on the outside of such pipe or core (Fig. 3, not shown), the baffles between adjacent turns being wholly or partly replaced by vertical partitions projecting inwardly from the shaft wall. The shaft may be used to preheat cement materials passing to a rotary kiln 2.

An upwardly-closing umbrella comprises telescopic ribs 11 and a telescopic handle which, in a collapsed and shortened state of the umbrella, contains the shortened ribs with a cover 6 folded therearound, and the ribs being supported on the top end of the handle when the umbrella is opened. The cover is secured to the outer ends of the ribs by balls 9, and parts of the cover loosely encircle innermost sections of each rib. Inner ends of the ribs are secured to a member 12, which is slidable within the handle, by projections (13), Fig. 3 (not shown). The upper end of each handle section has a diverging mouth 7 and a restricted neck 14, the neck on the lower section frictionally co-operating with an enlarged lowerend part 15 of the lower handle section to enable the handle to be maintained extended. The ribs may be locked in the extended position by frictional engagement between internal and external frustoconical surfaces on the ends of the rib sections. The covering can be stretched taut or loosened by movement of one or two ribs only. The handle may be made of stainless steel, the ribs of a harder tempered steel and the covering from thinfilm plastics material. When closed, the umbrella is stated to resemble a fountain pen in shape and size one end of the handle being provided, with a clip for carrying the collapsed umbrella secured by the clip to clothing.

Abstract: 1289264 # - Methoxyaldehydes MELLEBEZONS 19 April 1971 [30 April 1970] 23583/71 Heading C2C #-Methoxy aliphatic aldehydes are continuously produced by condensing methanol with C 4-5  α,#-olefinic aliphatic aldehydes by passing a liquid mixture of the reactants through a fixed bed of a catalyst comprising calcium, hydroxide deposited on an adsorbing carrier, e.g. silica. The catalyst is preferably prepared by contacting the carrier, preferably in the form of grains, with a wash of slaked lime in an inert organic liquid boiling below 80‹ C., e.g. an alkanol, dialkyl ether or hydrocarbon. The reaction zone preferably contains downstream of the catalyst bed. a bed of carrier having no lime deposited thereon to trap lime chromatographically eluted from the catalyst section. The catalytic section thus moves along the reaction zone and when it approaches the end, either the reaction vessel or the flow of reactants may be reversed. Additional slaked lime-wash may be added to the middle portion of the reaction zone at intervals to compensate for loss. Liquid distributing devices or materials may be provided at the liquid inlet points. Examples prepare #-methoxyisobutyraldehyde, #-methoxybutyraldehyde and #-methoxy-2-ethylpropionaldehyde from methacrolein, crotonaldehyde and ethacrolein respectively.
