IPC: B24B7/24
Filed: 1955-08-19
Abstract: 809,028. Grinding or polishing glass. GLACERIES DE LA SAMBRE S. A. Aug. 19, 1955 [Sept. 8, 1954], No. 23982/55. Class 60. Apparatus for grinding or polishing the lower face of a horizontal continuous sheet of glass 50, Fig. 1, includes a tool 2 having a hollow shaft 1 within which there is disposed a fixed tube 12 for feeding an abrasive mixture into the central part 10 of the tool, the annular space 14 between the tube and the shaft allowing abrasive mixture to leave the tool without passing between the working face of the tool and the glass so as to ensure continuity of circulation of the mixture regardless of the intensity of the centrifugal force acting upon the tool. Distributing blades 52 on an independently driven cup 53 impart the centrifugal action to the mixture. The mixture returning through the annular space 14 or through one or more of the annular spaces when the cup 53 is employed flows into a trough 11 and through a pipe 16 into a tank 17 from which it is raised by a pump 19 to abrasive grading tanks 21, 22 and 23 each feeding a separate rotary distributor 28. The abrasive mixture falls from the distributor 28 into a tank 35 which is divided into three separate compartments by three adjustable partitions 36, 37 and 38, each compartment supplying a separate pipe 48 feeding one of the tools 2. The overflow from the grading tanks 21, 22 and 23 also returns to the tank 17 together with the abrasive mixture which escapes between the tools and glass and which is collected by plate 54 and returned by a pipe 56. The hollow shafts 1 are driven by worm gearing 8 from an electric motor 9 and the rotary distributor 28 is driven by a belt 30. Valves 60, 61, 63 and 65 are provided so that when polishing felts are to be supplied the abrasive grading tanks 21, 22 and 23 may be omitted. Moreover water instead of abrasive composition may be supplied to the tools, the water being directed into an abrasive recovery tank (not shown) instead of into the reservoir 17. The polishing felts 67, Fig. 8, are provided with radial slots 68 and 69 and are mounted on a rigid backing plate secured to the shaft 1. The tools are carried by beams 5 which are reciprocated transversely of the direction of travel of the glass.

Title: Method for the production of trans or cis 2,5-dimethylpiperazine
IPC: C07D295/023
Filed: 1956-08-07
Abstract: The Specification claims the processes of (1) isomerizing cis - or trans - 2:5 - dimethylpiperazine to produce a mixture of the two by heating with a nickel-containing hydrogenation-dehydrogenation catalyst in an atmosphere of hydrogen (preferably under pressure); and (2) producing a mixture of at least 50 per cent of trans-2:5-dimethylpiperazine with some cis-2:5-dimethylpiperazine and 2:5-dimethylpyrazine by heating isopropanolamine to 180-260 DEG  C. under hydrogen pressure of at least 200 p.s.i. for at least 2 hours in the presence of a nickel hydrogenation-dehydrogenation catalyst. The equilibrium mixture obtained under these conditions contains about 80 per cent of the trans-compound so that process (1) can be used to enrich the trans-form if it is present initially to the extent of less than 80 per cent or to enrich the cis-form if less than 10 per cent thereof is present.  Similarly the amount of trans-compound resulting from process (2) can be increased by adding the cis-form to the isopropanolamine.  Preferred conditions for process (2) are a temperature of 200-240 DEG  C. (e.g. 220-240 DEG C.), hydrogen pressure of 800-1200 p.s.i., 4 hours or more of heating, and 1.25 g. or more (e.g. 2.5 g.) of an alloy sketal catalyst of the Raney nickel type.  Information is given as to the variation of yield and conversion under different experimental conditions.  The filtered reaction product is heated to distil off water and 2:5-dimethylpyrazine, and unreacted isopropanolamine removed as an azeotrope with ethylbenzene or xylene; these products can be recycled.  The cis- and trans-2:5-dimethylpiperazines may be partially separated by fraction distillation, the trans-form being purified by crystallization from a melt and the cis-form by solution in heptane.  This separation can be carried out continuously or batchwise, suitable plant for the former being illustrated. Specification 791,050 is referred to.
Patent GB-1111945-A (GB)
Title: Production of epoxy compounds
Inventor: RUSSELL JOSEPH LEE
IPC: C07C15/46
Filed: 1965-06-08
Abstract: Epoxy compounds are produced by contacting a hydrocarbon having a secondary or tertiary saturated carbon atom with molecular oxygen to produce an organic hydroperoxide, reacting the hydroperoxide in the liquid phase with an olefinically unsaturated hydrocarbon having the same carbon skeletal structure in the presence of a metal epoxidation catalyst to produce an epoxy compound and the alcohol corresponding to the hydroperoxide, dehydrating at least part of the alcohol to the corresponding olefinically unsaturated hydrocarbon and epoxidizing this unsaturated hydrocarbon in the epoxidizing reaction with additional amounts of the organic hydroperoxide. The preferred hydrocarbons used as starting materials are aralkanes having at least one carbon atom on the alkyl carbon adjacent to the aromatic ring, e.g. ethyl benzene, cumene, ethyl toluene, p-cumene, tetrahydronaphthalene, p-diisopropyl benzene, ethyl naphthalene, isopropyl naphthalene, p-diethyl benzene, p-tertiary-butyl ethyl benzene and phenyl cyclo-hexane. Other suitable starting materials are, e.g., isobutane, isopentane, cyclohexane, methyl cyclohexane, dimethyl cyclohexanes and 2,5-dimethyl benzene.  Suitable epoxidation catalysts are Ti, V, Cr, Se, Zr, Nb, Mo, Te, Ta, W, Re or U.  In the Examples: (a) cumene is oxidized to cumene hydroperoxide which is reacted with a -methyl styrene to give a -methyl styrene oxide and cumyl alcohol; part of the cumyl alcohol is dehydrated to a -methyl styrene which is recycled with the rest of the cumyl alcohol to the epoxidation step; (b) ethyl benzene is oxidized to ethyl benzene hydroperoxide which is used to epoxidize styrene and phenylethanol which is dehydrated to styrene and recycled to the epoxidation step.
