Abstract: 861,456. Malting. COLUMBIA MALTING CO. Sept. 24, 1957 [Sept. 24, 1956], No. 29967/57. Class 14 (2). [Also in Group XXV] A vertical malting apparatus has an air delivery 45 at the upper portion of the apparatus, a centrally-located air downtake 23 leading from the air delivery, a plurality of air uptake passages 61 around the air downtake and communicating with the downtake at its lower end 27 only, vertical grain holding bins 65, adjacent to the air uptakes, having perforated walls 97 communicating with the uptakes, a discharge air chamber 103 outwardly of the bins and the outer walls 101 of the bins are perforated and communicate with the air discharge chamber. Grain from a spout 87 is distributed by a rotary conveyer 93 through an annular closure plate 99 to a selected grain bin or bins 171 through which air from the air uptake passages 173, moistened when necessary by a water spray 35 in the downtake 23, is circulated for germination and drying, as the case may be. Loss of air is prevented by the closing of dampers 67 at the bottom of air uptake passages 177 disposed adjacent to empty bins 175 and by rendering a short upper section 98 of the walls 97 imperforate. The grain is released from a bin for stirring and aeration by opening doors 69 and falls into a V-shaped divider structure 19 (Figs. 3, 4 and 5, not shown), thence on to an elevating conveyer 83 from the top of which the grain is discharged downwardly into the spout 87 for redistribution in the bins; since the grain expands very substantially during the germination, additional bins 175 are brought into use as required. A reversible conveyer 91, Fig. 3 (not shown), brings steeped grain into the apparatus and carries away the finished malt. Figs. 7, 8 and 10 (not shown, see Group XXV) and Fig. 9 (not shown) depict the operation of grain bin doors 69 and dampers 67, respectively.

Title: Synthesis of oxygenated organic compounds from carbon monoxide and hydrogen
IPC: C07C27/22
Filed: 1952-11-26
Abstract: Aldehyde product from the carbonylation stage of an Oxo synthesis is decobalted by treatment with an aqueous solution of a cobalt salt. Cobalt hydrocarbonyl in the aldehyde product is thereby converted into the very water - soluble compound Co(Co(CO)4)2, recovered aqueous solutions of which may be recycled for use as carbonylation catalysts.  The recycled catalyst is preferably returned with recycle aldehyde cooling liquid.  Low molecular weight fatty acids are preferred cobalt salts and concentrations of cobalt are chosen to combine at least stoichiometrically with all the cobalt in the aldehyde product as carbonyl.  Make-up cobalt catalyst is preferably added in the decobalting zone.  Conventional conditions and feedstocks are described for the process the initial catalyst being an oil-soluble cobalt soap such as the oleate or naphthenate.  In the decobalting zone pressures of about 0-200 p.s.i.g., temperatures of about 50-200 DEG  F., preferably 100-185 DEG  F., and residence times of about 10-120 minutes are mentioned.  After separation from the aqueous cobalt compounds the aldehyde product may be hydrogenated to alcohols.  A diagram of suitable apparatus is provided and in examples decobalting is effected with aqueous solutions of cobalt acetate in the presence or absence of acetic acid, the aldehyde product being derived from heptenes.  Specification 647,363 is referred to.

Abstract: 758,432. Making seamless tubes. HUET, A. Dec. 21, 1951, No. 30005/51. Classes 83 (2) and 83 (4). Forging.-A tube is formed with a localized thickening in selected sectors by enlarging the diameter over a section of its length, heating the selected sectors and then deforming the tube to restore the original internal diameter and increase the wall thickness in the heated sectors. A tube b, Fig. 3, with an enlarged diameter portion is heated over the sector AB by blow pipes or electric induction and pressed between dies c, d to form an enlarged portion b1, Fig. 4. The tube may be subsequently re-calibrated internally or a mandrel may be introduced into the tube before it is deformed, the mandrel being cooled or thermally insulated. Alternatively the tube may be cooled internally by circulated air or water to maintain the interior more rigid. Tube bends may be made by bending the tube with the thickened sector on the outside of the bend. Heat exchange elements with multiple bends may be formed from a single tube or from straight tubes connected to short tube bend elements. In a modification tubes are formed with a pair of opposed thickened sectors by heating sectors CF, DE, Fig. 10, and compressing between dies g to form thickened portions h1, h2 and then compressing with further dies H1, H2 to form the final external shape. In another modification tubes heated over sections CF, DE Fig. 12, are formed between opposed dies k, l, the die k having recesses m in which the thickened sector portions n are formed.
