Title: Novel crystal form of copper phthalocyanine
Inventor: BRAND BORIS PETER
IPC: C09B67/12
Filed: 1960-02-19
Abstract: The invention comprises the delta-crystal form of copper phthalocyanine which is characterized in that the portion of its X-ray diffraction spectrum lying between about 4.5 and 6.0 Angstrom units contains only one line of any considerable intensity, namely a line corresponding to an interplanar spacing of from 5.0 to 5.05 Angstrom units.  The delta-crystal form is prepared by treating a finely divided copper phthalocyanine in alpha-crystal form with benzene or cyclo-1 : 3-hexadiene in the presence of a surface active agent and optionally in the presence of water.  Specified surface active agents include sulphated or sulphonated derivatives of unsaturated compounds such as methyl oleate and castor oil and polyethenoxy derivatives of alcohols and phenols.  Turkey Red oil is preferred.  The delta-crystal form is redder in shade than previously known forms of copper phthalocyanine.  Examples are given.  U.S.A. Specifications 2,334,812, 2,486,351 and 2,770,629 are referred to.

Title: Improvements in or relating to the production of oxygen-containing organic compounds
IPC: C07C45/50
Filed: 1951-03-12
Abstract: In an OXO synthesis using a "cobalt carbonyl" catalyst part of the reaction mixture, consisting at least in part of liquid phase material, is withdrawn from a point remote from the point of entry of the reactants, cooled and returned without phase separation to the reactor at a point nearer to the point of entry of the reactants and at a temperature not less than the minimum required for the synthesis.  The term "cobalt carbonyl" covers true carbonyls such as Co(CO)8 and carbonyl hydrides such as Co(CO)4H.  Temperatures specified are 80-180 DEG C.  Recycled material may be withdrawn and returned at a plurality of points. Cooling may be effected by heat exchangers.  Preferably the recycling rate should be high, e.g. at a volume flow rate of 5-50 times the rate at which fresh feed is passed to the reactor. Preferably the Reynolds number of the liquid in the heat exchanger is 10,000-30,000.  Preferably the temperature drop during circulation is relatively low, e.g. below 50 DEG C., preferably below 20 DEG C.  Preferred inlet and outlet temperatures vary with the olefine used and a table is provided giving these temperatures for a number of olefines.  The withdrawn stream may comprise gas and liquid or using upflow conditions through the reactor especially with C2-C4 olefines, liquid streams and gas streams are removed from different points and recombined before cooling. The liquid phase product stream may be combined with fresh CO and H2 before cooling.  Olefine hydrocarbons are preferred feedstocks but olefines containing such groups as ester, halogen, aldehyde and acetal may also be used.  Lower olefines, e.g. ethylene, propylene and butenes, are especially preferred.  It is particularly preferred that cobalt catalysts are not introduced in the solid phase.  Diagrams are provided of apparatus used when a single product stream is withdrawn and when separate gas and liquid streams are removed.  Specifications 647,363, 702,191, 702,192, 702,195, 702,196, 702,197, 702,201, 702,203 and 702,204 are referred to.
Patent GB-471130-A (GB)
Title: Manufacture of new aliphatic and cycloaliphatic halides
Filed: 1936-02-27
Abstract: An amide or urethane of the formula RCONHR<1> or ROCONHR<1>, where R and R<1> are aliphatic or cycloaliphatic hydrocarbon radicles, is treated with a hydrogen halide and formaldehyde or a polymer thereof such as paraformaldehyde, whereby products believed to be N-halogenmethyl derivatives of the amides or urethanes are obtained. The products are hydrolyzed by water and react with amines; they yield quaternary ammonium salts by addition of tertiary amines, particularly cycloaliphatic or heterocyclic tertiary amines such as pyridine or quinoline.  Both the N-halogenmethyl compounds and the quaternary salts obtainable therefrom are useful in textile-treating processes.  In the examples, (1) stearomethylamide (from stearic acid or stearyl chloride and methylamine) yields N-chloromethyl-N-methylstearamide by reaction with paraformaldehyde and hydrogen chloride; (2) methyl heptadecylcarbamate similarly yields N - heptadecyl - N - chloromethylcarbamic acid methyl ester; (3) methyl undecylcarbamate similarly yields N - undecyl - N - chloromethylcarbamic acid methyl ester; (4) methyl butylcarbamate similarly yields N - butyl - N - chloromethylcarbamic acid methyl ester; (5) acetoundecylamide (from acetyl chloride and undecylamine) similarly yields N-chloromethyl-N-undecylacetamide; (6) stearomethylamide, paraformaldehyde and hydrogen bromide yield N - bromomethyl - N - methylstearamide; (7) laurocyclohexylamide (from lauryl chloride and cyclohexylamine) yields N - chloromethyl - N - cyclohexyllauramide by reaction with paraformaldehyde and hydrogen chloride; the pyridinium salt obtainable from the product yields foaming aqueous solutions.  The reaction may be effected in the cold or at a moderately raised temperature, preferably in an inert diluent such as benzene and in the absence of water; the water formed in the reaction may be removed by azeotropic distillation or by addition of dehydrated magnesium sulphate.

Title: Improvements relating to wheel lathes
IPC: B23B5/28
Filed: 1928-03-01
Abstract: 306,290. Reed, F. W., and Craven Bros. (Manchester), Ltd. March 1, 1928. Lathe. driversand carriers.-In a wheel lathe each face-plate a is provided with arcuate slots f for the reception of T- headed bolts e which secure brackets b to the face-plates. Preferably, two brackets are mounted on each face-plate and each bracket supports a radially slidable head k adjusted by a hand-operated screw m. Blocks n are freely slidable parallel to the axis of the lathe in guides in the heads k and have slidable within them jaws p, o, Fig. 4, which telescope within each other. The inner jaws p have screwed extensions p<1> co-operating with nuts q formed on the outside as gear wheels which are rotated bv hand operated pinions r for closing the jaws against a spoke. The sliding stems t of the outer jaws o have secured entensions s engaging the ends of the blocks n so that if the jaws p meet the spokes before the jaws o their motion will be stopped and the jaws o, together with the nuts q and blocks n, will be drawn inwards and the spokes will be gripped between the jaws without imparting a lateral strain to them. Rotation of the extensions s by hand-operated rods v causes the initial opening of the jaws to be adjusted. The flanges of the wheels may be gripped by serrated pads 2, Fig. 1, axially slidable on the blocks n by means of screwed extensions thereon engaged toothed nuts 3 which are rotated by hand to bring the pads against the wheels and are then rotated by toothed racks x pivoted to pneumatic pistons y to give the final grip. When the pads 2 are not in use the racks x am moved to their extreme right hand positions as shown in Fig. 1, the teeth being then clear of the pinions 3. The. racks are pressed upwards by springs z and the first one or more teeth to engage the pinions are shortened to facilitate meshing. In operation, the brackets b are adjusted circumferentially by worms c rotatable thereon and engaging racks d on the face-plates and the heads k are adjusted radially to position the jaws adjacent the spokes. The jaws and pads 2 are then adjusted by hand to be brought into contact with the spokes and rims of the wheels and compressed air is admitted to the pistons h, y, the former actuating levers i attached to nuts g on the bolts e which secure the brackets. b to the face-plates and the latter actuating the racks x which rotate the pinions 3 to grip the wheels. The jaws o, p, may be used with or without the pads 2 and when the latter are used the jaws p may be dispensed with since the thrust between the pads and the jaws o is balanced. The air supply is conducted to the cylinders by axial passages in the mandrels and face plates leading to radial ports. According to the Provisional Specification the supply and exhaust connections to the axial passages are by pipes and annular ducts round the mandrels and two-way control valves, and air or other fluid pressure may be used.
