Abstract: 589,436. Printing-presses. FEENY,C. J. (Miehle Printing Press & Manufacturing Co.). July 21, 1944, No. 13992. [Class 100 (ii)] [Also in Group XXIV] A member, such as the bed 12 of a printing- press, is given a reciprocating motion, the middle portion of each stroke being at uniform speed and each end portion being made partly with uniform acceleration (or deceleration) and partly with continuously varying acceleration (or deceleration). Impulses transmitted to the parts are thus reduced. As shown, for a tworevolution press the bed 12 has a rack 18 always meshing a gear 19 on a shaft 20 which also carries non-circular gears 23, 24, and cam followerrollers 25, 26. Shafts 28, 32, driven at equal speeds in opposite directions from a main driving shaft 15, have non-circular gears 27, 31, engageable with the gears 23, 24, respectively. The shaft 32 also carries cams 35, 36, engageable with the follower-rolls 25, 26. The gears 23, 24, 27, 31, may be formed in the manner described in U.S.A. Specifications 2,253,270 and 2,302,942. The impression cylinder 13 is driven from the shaft 15 by gears 16, 17. In operation, for the major portions of the printing and return strokes the shaft 20 is driven by the gears 27, 23 and 31, 24, respectively, the gears being shaped to give the uniform motion and the continuously varying acceleration (or deceleration) motion. the return stroke being made at a greater speed than the printing stroke. At the stroke ends the drive is taken over by the cams 35, 36; acting on the follower-rollers 25, 26, to produce reversal in the direction and the uniform acceleration (or deceleration) of the bed 12. Specification 417,301 also is referred to.

Abstract: 209,704. Martin, J. Jan. 12, 1923, [Convention date]. Addition to 197,947. Grates.-A process for the combustion of fuel on furnace grates as described in the parent Specification comprises continuously turning a mass of thickly heaped fuel and advancing it up the slope of an inclined grate by mechanically-operated stoking elements. The operation is carried out on a step grate inclined upwardly towards the discharge end and comprising fixed steps or bars a and reciprocating bars d which are moved in opposite directions and serve to agitate and feed the fuel up the grate. This movement of the bars d results in the periodic temporary formation of steep recesses in front of the fixed bars. The final step works on to an ash grate e which is inclined and adjustable in height, thereby controlling the advance of the fuel up the grate. The bars are preferably hollow and perforated for the passage of combustion air.

Patent GB-616829-A (GB)
Title: Improvements in and relating to the production of alkyl phenols
IPC: C07C37/14
Filed: 1946-05-17
Abstract: Phenol is butylated with isobutene in the presence of sulphuric acid at a temperature not exceeding 70 DEG  C. and the reaction products are then isomerized to yield p-tertiary butyl phenol by heating at a higher temperature less than 150 DEG  C.  The sulphuric acid acts as a catalyst and should preferably be not more than 5 per cent by weight of the weight of phenol used. p-Tertiary-butyl-phenol formed may be isolated by any convenient means, but more particularly by (a) cooling the reaction product to about 15 DEG  C., separating off the solid by filtering or centrifuging, neutralizing excess acid in the solid and fractionally distilling the neutral solid to give the pure phenol, or by (b) neutralizing the final reaction products, cooling, separating the solid product by filtering or centrifuging and purifying by distillation.  The process may be made continuous by returning the mother liquors obtained after the separation of the solid product back to the butylation stage.  A temperature range of 30-70 DEG  C. is preferred for butylation and of 100-150 DEG  C. for isomerization.  The isobutene used may be admixed with other paraffin hydrocarbons or butenes.  In an example, phenol in the presence of sulphuric acid is treated at a temperature of 60-70 DEG  C. with a gas containing on a percentage molar basis 18 per cent of isobutene, 7 per cent of normal butene and 75 per cent of butenes until the increase in weight corresponds to the absorption of four gram-molecules of isobutene.  The product is heated for two hours at 150 DEG  C. and after cooling is centrifuged to separate solid p - tertiary - butyl - phenol, the mother liquor being returned to the butylation step together with further quantities of phenol and sulphuric acid.  This latter mixture is again butylated and the p-tertiary-butyl-phenol separated as above described.  This cycle of operations is repeated thirteen times, the p-tertiary-butyl-phenol obtained being purified by distillation after treatment with an aqueous solution of sodium carbonate.
