Title: Light sensitive aluminium supports for the production of planographic printing plates
IPC: G03G5/087
Filed: 1960-12-28
Abstract: 912,130. Light-sensitive material for printing plate production. KALLE A.G. Dec. 28, 1960 [Dec. 30, 1959], No.44460/60. Class 98 (2). An aluminium support is provided with a surface layer of " Bohmit " and a light-sensitive coating adherent thereto. The " Bohmit " (Al 2 O 3 , 1H 2 O) is formed by treatment of the aluminium with water or steam at a temperature above 75‹ C. preferably in the presence of weakly basic agents, and provides good adhesion for the light-sensitive coatings and a highly hydrophilic surface after removal of the latter. Ten examples detail the procedure for lithographic plate production, thus in Example 1 a strip of untreated rolled aluminium is drawn through 2% ammonia solution at 80 C. allowing immersion time of about 10 minutes, rinsed with distilled water, dried, coated with an ethylene glycol monomethyl ether solution of naphthoquinone - (1,2) - diazide - (2) - 5 - sulphonic acid ester of 2,3,4 - trihydroxy benzophenone, dried again, cut up into sheets, exposed under a master, treated in a 3 % trisodium phosphate solution to remove unexposed parts of the coating, rinsed and inked up for use as in a run twice as long as that using mechanically roughened aluminium and superior to such with a silicate coating. In a somewhat corresponding manner the materials to facilitate " Bohmit " production and sensitize the result of the other examples are (2) monoethanolamine and 4- diazodiphenylamine formaldehyde condensation product; (3) ethylene diamine; and (4) steam only with a similar diazo sensitizer; (5) triethanolamine and cinnamylidenefurfurylidene-acetone; (6), (7), (8) and (9) " Bohmit " production as in Example 1 with 4,4<SP>1</SP>-diazidostilbene - 2,2<SP>1</SP> - disulphonic acid, N - (4<SP>1</SP> -  methyl - benzene - 1<SP>1</SP> - sulphonyl) - imino - (1)- 2,5 - diethoxybenzene - (1,4) diazide - 4, 2,2<SP>1</SP> -  bis - [naphthoquinone - (1,2) - diazide) - (2)- sulphonyloxy - (5)] - dinaphthyl - (1,1<SP>1</SP>)- methane and 2,5 - bis - [4<SP>1</SP> - diethylamino - phenyl- (1<SP>1</SP>)] - 1,3,4 - oxadiazole with a styrene interpolymer respectively as sensitizers the last of these following electrostatic image production procedure.

The compounds can be made by reacting a propane sultone of the formula <FORM:1030888/C3/5> with a silane or siloxane according to the equation <FORM:1030888/C3/6> where V symbolises the rest of the molecule, consisting of Z and/or siloxane groups, h is the valency of Y divided by the valency of M, and each Q1 is H or an alkyl radical. The reaction can be effected in a solvent, such as methanol or benzene, at 20 DEG  to 150 DEG  C.  In typical Examples, (1) on adding 3-hydroxy-1-propane sulphonic acid sultone to a benzene solution of <FORM:1030888/C3/7> at 27 DEG  C., an exothermic reaction occured to yield, after removal of solvent, a siloxane having the H atoms attached to N atoms (in terminal groups) replaced by -(CH2)3SO3H groups; (2) in a similar manner the sultone was reacted with (CH3O)3Si(CH2)3NH.CH2.CH2. NH2 to yield (CH3O)3Si(CH2)3NH.CH2.CH2.NH. (CH2)3SO3H.  Uses.-As detergents, ion exchange resins, wetting agents, antistatic agents for synthetic fibres, and as polymerization catalysts for siloxanes.ALSO:Sulphopropylated organofunctional silanes and siloxanes (see Division C3) are useful as antistatic agents for synthetic fibres. In Example 7, pieces of nylon fabric are dipped into methanol solution of the products of Examples (1) and (2), and air dried; the treated pieces when rubbed several times with a glass rod did not pick up ashes when placed over (but not in contact with) cigarette ashes.

Title: Rapid set mechanism for calendar timepieces

Filed: 1970-09-21
Abstract: 1308352 Calendar timepieces HAMILTON WATCH CO 21 Sept 1970 [19 Feb 1970] 44901/70 Heading G3T The hands and a date dial 40 of a timepiece are met by a stem 44 having a rectangular shaft position 50 and a slot, with a shoulder 48, with which engages a follower of a setting lever 78. Inward movement of the stem 44 causes lever 78 to rotate a lever 94 to cause a serrated clutch member 62 to slide along the piston 50 to engage a ridged member 70 which is prevented from rotation by abutment with case. The calendar ring is then set by rotation of the stem against the action of the clutch 62, 70 through a pawl 116 and a pawl spring 120 whereby each rotation of the pawl advances the dial 40 by one tooth 42. Reverse rotation of the calendar dial is prevented by the pawl pivoting about a pin 118 against a spring 120 to ride over teeth 42 without effecting a driving action. When the stem is moved outwardly the clutch members 62, 70 are separated and a lever arm 100 causes the stem to be coupled with the dial train to set the hands of the timepiece.

Abstract: 1276776 Pyridine carboxylic acids LONZA Ltd 22 Sept 1970 [24 Sept 1969] 45147/70 Heading C2C A pyridine-carboxylic acid is prepared by oxidizing an alkyl-pyridine and/or a heterocyclic compound which carries a pyridine nucleus and which is substituted in at least one position by a group which is oxidizable under the reaction conditions to a carboxylic acid radical, comprising passing at least one said alkyl-pyridine or heterocyclic compound with an excess of nitric acid through an inert flow tube at a temperature of 180-370‹ C. and pressure of 20-500 atmospheres, the reaction temperature being attained and maintained by generating the thermal energy required directly in the wall of the flow tube and discharging the product from the flow tube. An electric current may suitably be passed through the material of the flow tube e.g. by making it the secondary winding of a transformer and the part of the flow tube which forms the reaction path is short-circuited. Advantageously, the pressure and temperature of the reaction product are partially reduced, prior to its discharge from the flow tube, by a baffle system connected before a discharge valve in the flow path. An example describes the preparation of nicotinic acid and the process may be used to prepare picolinic, and cinchomeric acids.
