Title: Improvements in and relating to flat bed printing machines
IPC: B41F3/36
Filed: 1923-09-27
Abstract: 225,321. Bonham, H. Sept. 27, 1923. Inking - apparatus. - The inking-rollers of cylinder printing-machines for printing from intaglio plates are positively driven when the ink is being applied to the plate, and on the return stroke the doctor blade is raised and a feedroller or inking-roller is operated to arrest the ink supply. This invention is particularly applicable to machines of the two revolution type wherein the cylinder is reciprocated over the bed and rotated in one direction by fixed racks on the bed, as set forth in Specification 160,685. In the construction shown in Fig. 1, ink is transferred from a metal roller g rotating in a trough h by a composition roller n<1> to another metal roller g<1>, and thence by a composition roller l to the intaglio plate s. The roller g<1> is driven from one of the racks on the bed through a pinion k, and drives the trough roller g by means of a chain j. The roller g is geared to the roller n<1> and the roller g<1> to the plate-inking roller l. The roller n<1> is carried in arms n pivoted to the shaft of the roller g and connected by links p to arms p<1> on a shaft f, which carries the doctor wand an arm q having a roller q<1> engaging a cam r driven by two to one reducing gear r<1> from the shaft of the cylinder b. At the time the carriage b<1> moves to the right, which is the non-printing stroke, the roller q<1> engages the low part of the cam r so that the doctor w is lifted from the plate s and the, roller n<1> away from the roller g<1>, thus interrupting the ink supply, whilst during the printing stroke of the carriage to the left, the doctor wand roller n<1> are lowered. In' the modification shown in Fig. 3, the trough roller t is driven by a chain and sprocket wheels t<1>, t<2> from a spur wheel t<3> gearing with a spur wheel t<4> in mesh with a rack on the bed. The plate inking-roller u is driven by the roller t and is carried by pivoted arms v connected by links z to the arms carrying the doctor blade, which is actuated as before by a cam r and arm q so that the doctor blade and inking-roller are lifted during the non-printing stroke of the carriage to the right.

Abstract: 992,727. Starting I.C. engines. JOSEPH LUCAS (INDUSTRIES) Ltd. June 17, 1963 [June 25, 1962], No. 24269/62. Heading F1K. [Also in Division H2] In an I.C. engine starter in which a solenoid 16 acts through a lever 14 pivoted about an axis fixed relative to the motor to move a pinion 9 into engagement with a wheel 10, a spring 20 between the lever and the armature 17 allows the motor switch 26 to be closed in the event of tooth to tooth engagement of the pinion and wheel. When the solenoid is energized armature 17 moves a contact 27 through a hollow push rod 28 to bridge fixed contacts 26 thereby energizing part of the motor field. Lever 14 moves collar 12 and uni-directional clutch 8 axially thus causing pinion 9 to be rotated by screw thread 13 as it moves into engagement with wheel 10. A push rod 30 bridges a second pair of contacts (not shown) to energize the remaining part of the motor field. If the solenoid 16 is not energized and friction prevents disengagement of the pinion teeth, a lost-motion spring 24 compresses to allow spring 20 to move the armature thus opening both switches to de-energize the motor. In a modification the contact 27 controls the entire motor field system.

Patent GB-756408-A (GB)
Title: Improvements in the manufacture of phenol and cresols
IPC: C07C39/04
Filed: 1954-08-23
Abstract: In the decomposition of iso-propylbenzene hydroperoxide or of a cymene hydroperoxide with sulphuric acid to produce phenol or a cresol and acetone, the sulphuric acid in the crude decomposition mixture is neutralised by the addition of an aqueous alkaline solution containing from 10 to 60 per cent by weight of the alkali-metal salt of the phenol produced in the decomposition, prior to fractional distillation of the mixture to obtain the phenolic products.  The aqueous alkaline solution may contain in addition up to 20 mol. per cent of free alkali-metal hydroxide, based on the total alkali-metal present in the solution.  An excess of the aqueous alkaline solution over that required for neutralisation of the sulphuric acid may be used but the alkali-metal hydroxide content should not be more than 20 mol. per cent of that required for the complete neutralization of the acid. The alkali-metal specified is sodium.  The alkali-metal sulphate formed by the neutralization is removed by filtration prior to fractionation.  The process may be a batch one or continuous.  In examples: (1) cumene hydroperoxide was decomposed with sulphuric acid in acetone, the acid neutralized with 10 percent sodium phenate solution, the mixture filtered, acetone, isopropylbenzene and a -methyl-styrene removed by distillation and phenol obtained by fractionation; (2) in a continuous process the a -methyl-styrene-phenol azeotrope fraction from the distillation of the decomposition product of cumene hydroperoxide was extracted with sodium hydroxide solution to give sodium phenate solution containing free alkali; the acetophenone-phenol azeotrope fraction was similarly treated and the phenate solutions combined and used to neutralize the acid catalyst in a further decomposition reaction mixture which was filtered and distilled to recover phenol, plus an acetophenone-phenol azeotrope and an a -methyl-styrene azeotrope which were then recycled; (3) the neutralization of a cumene hydroperoxide decomposition mixture with sodium phenate is compared with neutralizations using calcium hydroxide, sodium carbonate (anhydrous), sodium bicarbonate, sodium carbonate solution and sodium hydroxide; (4) neutralization of a cymene hydroperoxide decomposition mixture with sodium p-cresylate is described and compared with a similar neutralization using sodium hydroxide.
