Title: Photographic printing apparatus
IPC: G03B27/30
Filed: 1958-11-10
Abstract: 849,989. Photographic contact-printing and developing apparatus. TECNIFAX CORPORATION. Nov. 10, 1958 [Nov. 13, 1957], No. 36034/58. Class 98(2) In an ammonia contact printer and developer, the printing cylinder is movable as on a carriage into and out of engagement with the belts for carrying the material during exposure. As shown, the printing cylinder assembly 28 is movable on racks 56 to a position away from the gas developing apparatus, leaving belts 22 hanging slackly from roller 24. In use, the belts 22 are tightened against the cylinder 30 and assisted by suction chamber 38, convey the exposed sheets to the gas developing apparatus including a developing tank 16 having a sealing sleeve 220 and an ammonia tray 18. The developed prints are stacked in tray 52 by belt 50. Belt driven vacuum roller 42 on assembly 28 peels off the originals which are stacked on tray 44. Assembly 28 is locked in its operative position by spring urged bolts 162 operated by knobs 170. With the bolts latched in their unlocked position the assembly 28 may be withdrawn along racks 56 (on which it runs on pinions 58, 60), the drive 184, 186 to belts 40, 46 and 34 being disengaged and switch 202 being opened to disconnect the main drive motor. The lamp cooling air circulation system is interrupted as pipe 114 feeding semi-cylindrical chamber 72 is'moved out of register with compressed air supply pipe 126. The air stream passing circumferentially around lamp 76 is exhausted through apertures 120 while these are in register with vacuum chamber 121. The mouth 124 of vacuum chamber 121 is spring urged against member 119 and the chamber exhausts suction chamber 38 and fume collecting conduits for the gas developing apparatus through a flexible hose (not shown) connected to its basal outlet. Complete withdrawal of assembly 28 leaves mouth 124 entirely open. Cylinder 30 is rotatably mounted on the side plates of assembly 28 by bearing members 66 and is located endwise by end bearings 68. The shutters 90 span cylinder 30 and are separately operated by milled wheels 112 through a chain drive operating racks 101 of sliders 96 carrying U-shaped members 94. In use, compressed air is diverted from pipe 116 by a deflector (Fig. 8, not shown) to an air jet device 36 which prevents the sheets from sticking to cylinder 30 and suction roller 42 is connected to vacuum chamber 121. The electrical lead to lamp 76 passes over pulley 152 and is held in a loop by pulley and weight 154 to allow for the movement of assembly 28.

Abstract: Unsaturated alcohols are produced when aldehydes of the general formula <FORM:0843585/IV(b)/1> , in which R1 and R are alkyl groups, and having more than 5 carbon atoms in the molecule, are reduced with a primary or secondary alcohol in the presence of a catalytic amount of aluminium alcoholate.  Suitable alcohols are, for example, isopropanol, secondary butanol, cyclohexanol, ethyl alcohol and butyl alcohol.  Suitable starting aldehydes are, for example, 2-methyl-butene-2-al, 2-ethyl-butene-2-al, 2-methyl-pentene-2-al, 2-ethyl-pentene-2-al, 2-methyl-hexene-2-al and 2-ethyl-hexene-2-al. The process may be carried out continuously. In the examples (a) 2-methyl-pentane-2-al is reduced with secondary butanol in the presence of aluminium secondary butylate to give 2-methyl-pentene-2-ol, the secondary butanol being oxidised to methyl ethyl ketone; (b) 2-ethyl-hexene-2-al is reduced with isopropanol in the presence of aluminium isopropylate to give 2-ethyl-hexene-2-ol, the isopropanol being oxidised to acetone; and (c) 2-ethyl-hexane-2-al is reduced with secondary butanol in the presence of aluminium secondary butylate to give 2-ethyl-hexene-2-ol the secondary butanol being oxidised to methyl ethyl ketone.

Title: A novel acetylene-carbinol compound and a process for the manfacture thereof
Filed: 1954-12-23
Abstract: The invention comprises the new compound 1 - hydroxy - 3 - methyl - 5 - (11 - hydroxy-21,61,61 - trimethyl - cyclohexyl) - pentene - (2)-ine-(4).  It is prepared by reacting 2,6,6-trimethyl-cyclohexanone in an inert solvent with an organo metal compound of 1 hydroxy-3-methyl - penten - (2) ine - (4) and hydrolysing the product.  The preferred metal compounds are an organo-lithium compound or a Grignard compound and they may be formed by reacting two mols. of a lithium compound, such as butyl lithium or of an alkyl magnesium halide with 1 - hydroxy - 3 - methyl - pentene - (2) - ine-(4) in an inert solvent such as ether.  In the example a Grignard solution is prepared from magnesium, methyl iodide and ether and 1-hydroxy - 3 - methyl - pentene - (2) - ine - (4) is added to it; 2,6,6,-trimethyl-cyclohexanone in ether is added to the resulting mixture and the product is hydrolysed with ammonium chloride to give a mixture which on distillation gives the new compound.  The novel compound obtained may be reduced by lithium aluminium hydride and then oxidized with manganese dioxide to give 3 - methyl - 5 - (11 - hydroxy - 21,61,61-trimethyl cyclohexyl)-pentene-(2)-ine-(4)-al - 1.

Title: Cycloundecane-1,2-dicarboxylic acids and their anhydrides
IPC: C07C/
Filed: 1961-10-17
Abstract: The invention comprises cis- and transcycloundecane-1, 2-dicarboxylic acids and their corresponding anhydrides.  The diacids are prepared by reacting an alkali metal hydroxide or an alkali metal alcoholate with a compound conforming to one of the formula: <FORM:0959411/C2/1> wherein R represents a hydrogen atom or an alkyl radical containing 1 to 5 carbon atoms and Hal represents a halogen atom, and acidifying the reaction mixture, the reaction being effected (a) when R is a hydrogen atom, with a said hydroxide in aqueous medium and (b), when R is an alkyl radical either with a said hydroxide in alcoholic or aqueous-organic solution or with a said alcoholate in alcoholic solution, with the additional step, where R is an alkyl radical and the reaction is carried out with a said alcoholate in alcoholic solution, of saponifying after the acidification the resultant diester with an alcoholic solution of an alkali metal hydroxide and subsequently acidifying the saponification mixture. Suitable alcoholic solvents are methanol and ethanol, and suitable aqueous-organic mixtures are mixtures of water with ethanol, methanol or dioxan.  The reaction may be carried out from 20 DEG C. to the reflux temperature of the reaction mixture. After acidification of the reaction mixture the mass obtained may be extracted with an organic solvent, e.g. diethyl ether or benzene, whereby a mixture of isomeric diacids is obtained from which the individual components may be separated e.g. by fractional crystallisation or distillation. It is also possible to omit the extraction phase, allow the isomeric cyclaric diacids to crystallise and then separate the isomers by fractional crystallisation. In Example (1) to the isomeric mixture of diacids obtained by the action of an ethanolic solution of potassium hydroxide on ethyl-1-bromo-2 oxocycloundecanecarboxylate, ether is added, and the mixture brought to boiling with stirring. A precipitate of trans cycloundecane-1, 2-dicarboxylic acid is obtained.  The filtrate is evaporated to give a viscous oil which, on distillation gives a middle fraction, which, on recrystallisation from ether gives the anhydride of the cis form of cycloundecane-1, 2-dicarboxylic acid. The conversion of the anhydride of the cis acid into the cis diacid and trans diacid, and the conversion of the trans diacid into the corresponding anhydride is also described.  The alkyl 1-halo (or 3-halo) -2- oxocyclododecane-carboxylates and 1-halo (or 3-halo) -2-oxocyclododecane carboxylic acids used as starting materials may be obtained by the action of solid CO2 or an alkyl carbonate, e.g. ethyl carbonate, on the sodium salt of cyclododecane to produce an alkyl oxocyclododecane carboxylate or 2 oxocyclododecane carboxylic acid, followed by halogenation by the direct action of a halogen, e.g. chlorine or bromine.
