Title: Inking mechanism for rotary printing machines
IPC: B41F31/30
Filed: 1963-06-25
Abstract: 1,030,324. Printing machines. AGFA A.G. June 25, 1963 [June 29, 1962], No. 25257/63. Heading B6C. In a rotary printing machine e.g. a lithographic offset machine, cam means are provided whereby when the forme-inking roller 9 is lifted off the printing cylinder 2 during interruption of printing operations, the roller is also removed from contact with a distributing roller 5 mounted on a fixed spindle 4. As applied to an arrangement, Fig. 4, wherein dampening liquid from a duct 12 and ink from a duct 28 are received by the axially-reciprocated distributing roller 5, the liquid duct-roller 10 and the inking roller 9 are mounted on bearings 7, 8 slideable in slots 6a, 6b on levers 6 pivoted on the spindle 4. Springs 16, 17 urge the rollers 9, 10 into engagement with roller 5 and a spring 11 acts on the levers 6 to move the roller 9 into engagement with the cylinder 2. A roller 40 of the ink-supplying devices also engages the roller 5 and its bearings 41 are slidable in fixed guides 42. Rotatably mounted on the spindle 4 is a cam member 39 operable by a setting lever 34. When the cam 39 is rotated clockwise, surfaces 39a, 39b and 39c of the cam engage the bearings of the rollers 9, 10, 40 and move the rollers away from the distributing roller 5. Upon further rotation, a stop surface 39c on the cam engages the bearing 7 and moves the levers 6 so that the roller 9 is raised from the cylinder. Another set of three rollers 47, 44, 49 is mounted on levers 45 pivoted about a spindle 43 in a similar manner to the rollers 9, 5, 10, the roller 44 being reciprocated axially. The rollers 47, 44, 49 engage respectively the roller 40, a polished roller 54 spring-urged towards its roller 44 and a messenger roller 33 oscillating between a duct roller 25 and its roller 49. A cam 52 pivoted on the spindle 43 has surfaces which lift the rollers 47, 54 and 49 from the roller 44 when it is rotated clockwise. The cam 52 is coupled by linkage 52e, 58, 39e to the cam 39 so that operation of the cam 39 actuates the cam 52 which through a stop part 52c moves the levers 45 clockwise so as to disengage rollers 47, 49 from rollers 40, 33 respectively. In a simplified arrangement, a roller 33, Figs. 1, 3 (not shown), engaging the distributing roller 5 in a similar manner to the roller 40, is a messenger roller and conveys ink directly from a duct roller 29 to the roller 5. In this arrangement, a cam 19 driven from the gears of roller 5 oscillates a lever 22, Fig. 3, advancing the duct roller step-by-step through a ratchet-andpawl device 23, 24. The operative stroke of the pawl 23 is determined by a pin 37b on a lever 37 which can be set by a pin-and-slot device 37a, 3d. When the lever 34 is operated to separate the rollers as described above it renders the duct-roller feed inoperative through a member 35 which engages a pin 22a on the lever 22 and moves the lever away from the cam 19.

Patent GB-482126-A (GB)
Title: Improvements in the manufacture of alkylolamines
IPC: C07C215/08
Filed: 1936-09-19
Abstract: Alkylolamines are prepared by treating an aliphatic compound containing a primary or secondary amino radicle attached to a carbonyl group with an oxyalkylating agent and hydrolyzing the N-oxyalkyl product.  Aliphatic compounds mentioned are acetamide, diacetamide, ammonium carbamate, ethyl carbamate, urea and alkylureas.  The hydrolysis is effected with dilute acid or alkali or by hot water under pressure.  The reaction with the oxyalkylating agent, e.g. ethylene oxide or ethylene chlorhydrin, may be carried out at ordinary or increased pressure, preferably using a large excess of the aliphatic amino compound.  According to the example, ethylene oxide is passed into an aqueous solution of acetamide and the product heated with sodium hydroxide to give monoethanolamine. Reference is made to the production of the same compound by reacting ammonium carbamate in aqueous solution with ethylene oxide or ethylene chlorhydrin, preferably in the presence of alkali, and then heating the product; also to the production of 1-amino-2 : 3-hydroxypropane using a -monochlorhydrin and acetamide, and to the preparation of monopropanolamine from 1-hydroxy-3-chlorpropane.  The Provisional Specification describes the compounds which are treated with oxyalkylating agents as compounds containing the amino radicle, suitably those containing a carbonyl group attached thereto, and including thiourea.

Patent GB-663094-A (GB)
Title: Improvements in or relating to the production of resins from phenolic mixtures
Inventor: CLAMER JACQUES
Filed: 1948-10-01
Abstract: The process described in the parent Specification for producing water-insoluble resins wherein phenolic mixtures are treated with lower aliphatic aldehydes in steps, the reaction conditions becoming more severe with successive steps to combine the less-reactive phenols, is modified so that the resins produced in one or more steps are soluble in water.  The modification is in the condensation time, the condensation temperature or the concentration of the aldehydes. In examples: (1) 100 parts of phenolic oil containing 35 per cent phenols and 18 parts of 30 per cent formaldehyde are heated to 50 DEG C. and the temperature allowed to rise to 60 DEG  C.  Then 1.8 parts of 30 per cent caustic soda are added, the temperature maintained at 60 DEG  C. for one hour and the mixture separated into a resin dissolved in caustic soda and a partially dephenolized oil.  The oil, containing 22 per cent phenols is treated with 18 per cent of formaldehyde and 1.8 parts of caustic soda to produce a second resin solution and an oil which may again be treated.  (2a) The mixture of phenolic oil and formaldehyde of example (1) is heated to 97 DEG  C. and the reaction stopped three minutes after the caustic soda is added by cooling rapidly.  (2b) A mixture of phenolic oil, formaldehyde and caustic soda solution in the proportions given in example (1), which may be preheated in heat exchanger, flows through a heated coil; passage of the mixture through the coil taking about 3 minutes. The mixture then flows through a refrigerant or heat exchanger and is separated into a resin dissolved in caustic soda and a partially dephenolized oil which may be treated as before. Aqueous solutions of the resin may be used for impregnating purposes and the dehydrated solid resin may be used to make alcohol varnish or moulding powders.  The Specification as open to inspection under Sect. 91 is not limited to lower aliphatic aldehydes but refers also to cyclic and acyclic aldehydes and ketones.  This subject-matter does not appear in the Specification as accepted.
