Title: Improvements in and relating to epoxides
IPC: C07D303/14
Filed: 1957-12-16
Abstract: An epoxide is formed from a liquid medium containing an olefinically unsaturated compound, hydrogen peroxide, a catalytic concentration of a peracid of an oxide of a metal of Group IV, V, VI or VIII of the Periodic Table or a peracid of a heteropolyacid, and an inorganic or organic alkaline-reacting substance in quantity sufficient to alter the pH of the medium to a value of below 7 and at least 3. Preferably the medium is an aqueous liquid medium maintained at a pH from 4 to 6.  The alkaline substance may be an aliphatic, cycloaliphatic, aromatic or heterocyclic, primary, secondary or tertiary amine in an amount of 0.005 to 2% by weight of the reaction medium. Alternatively ammonia or alkali metal or alkaline earth metal carbonates, hydroxides or phosphates may be employed.  Per acids of oxides of Ti, Zr, V, Ta, Cr, Mo, W, U and Ru are suitable.  Per acids of heteropolyacids include those of S, Se or Te with Mo or W.  Per acids of molybdotungstic and chromotungstic acids are also suitable.  The per acid may be added as such or formed in situ, an amount of 0.01 to 2% of per acid by weight of the reaction medium being suitable. Aqueous hydrogen peroxide solutions may contain 3 to 90% H2O2 by weight.  Reaction temperatures are generally in the range from 0 DEG to 100 DEG  C.  The epoxidations may be performed in a medium in which water is the sole inert diluent but other diluents such as alcohols, ketones, ethers and halogenated hydrocarbons may be used. The compound epoxidized may be an olefinically unsaturated mono or polyhydric alcohol which may be aliphatic, cycloaliphatic, aromatic or heterocyclic containing from 3 to 15 carbon atoms or a halogenated, particularly chlorinated alcohol.  1 : 2-Epoxycyclopentanol-3 and 1 : 2-epoxybutanediol-3 : 4 are novel compounds.  Epoxides of methyloleate and similar esters, butadiene and cyclohexene may also be prepared.  The epoxy alcohols are useful as intermediates in the preparation of epoxy-substituted esters of silicon acids and for the formation of epoxy resins.  The epoxides or their hydrolysis products may be esterified with acetic or propionic acid to form esters which are useful plasticizers for polyvinyl chloride.  Specification 754,359 is referred to.ALSO:Epoxy alcohols, such as 1 : 2-epoxycyclopentanol-3 (for preparation see Group IV (b)), are polymerized by virtue of the epoxy group by heating in the presence of stannic chloride or other epoxy-polymerization catalyst; 1 : 2-epoxy-cyclopentanol-may also be heated with phthalic anhydride to form a resin.  The epoxy alcohols may be hydrolysed under mildly aqueous acidic conditions to obtain polyols.  In the case of monohydric epoxy alcohols, triols are obtained which are esterifiable with acetic acid or propionic acid to produce polyesters which are plasticizers for polyvinyl chloride and like materials. Specification 754,359 is referred to.

Title: Improvements in or relating to apparatus for measuring the speed of moving targets by doppler effect
IPC: G01S13/92
Filed: 1957-12-17
Abstract: 813,168. Radar. TELEFUNKEN G.m.b.H. Dec. 17, 1957 [Dec. 22, 1956], No. 39182/57. Class 40 (7). The invention relates to an apparatus for measuring the speed of moving targets and has provision to make the apparatus responsive only to approaching or to receding targets. In one embodiment a radar transmitter S feeds an aerial SA by means of a waveguide H1. Echo signals received by reflection of the transmitted waves from a moving target are passed from aerial EA to a guide H2 which is split as shown in Fig. 1. Detectors D1 and D2 are placed at the ends of these branches, the two paths from the aerial to the detector being equal or differing by a whole number of wavelengths at the frequency of transmission. A portion of the transmitter energy is fed to the branches of the guide H2 by means of directional couplers R1 and R2, the arrangement being such that the transmitted oscillations at the couplers are in phase quadrature. At the output of the detectors appear the sum and difference frequencies of the transmitted and received frequencies and each detector feeds a narrow-band amplifier V1 or V2 which amplifies the difference, or Doppler, frequency only. The outputs from the amplifiers will be, for example, E1 and E2 and will be in phase quadrature, E1 lagging or leading E2 depending upon the direction of motion of the target, Figs. 2a and 2b (not shown). By means of a phase shifter P a further shift of 90 degrees is given to E1 or E2 and this signal combined with the non-shifted signal in a combining transformer T. Means, not shown, may be provided in one of the channels to the transformer to ensure that the amplitudes of the two signals fed to the transformer are equal, the signals will then either add in phase or cancel each other. The transformer feeds to a frequency meter which is used to measure the speed of the target. The apparatus thus distinguishes between approaching and receding targets and indicates the speed of the former or the latter dependent on the position of the switch U. The phase-shifter P is described in the Specification with reference to Fig. 3 (not shown) and a preferred form of phase-shifter with reference to Fig. 4 (not shown).

If a given bit position is not the same in all the words then it will be 0 at least once and 1 at least once so the ORing will give 1 and the ANDing will give 0, and so the EXCL-ORing will give 1. Otherwise the EXCL-ORing will give 0. It is stated that whether the error involves a 0 substituted for a 1 or vice versa can be determined from the final contents of the two registers. Each word may be the concatenation of the outputs of an arithmetic-and-logic-unit, two operand registers feeding it, a result register fed from it and a parity error bit, and may be stored in an error store on detection of a parity error at the output of the result register, the error store feeding the ORing and ANDing &c. arrangements above. The two registers in the latter may be addressable locations in the error store.

Title: Improvements relating to the preparation of cyclohexanone oxime and other oximes
Filed: 1961-11-16
Abstract: Oximes are purified by adding to a nonacidic mass containing the oxime and as a minor ingredient one or more amines, at a temperature of 25 DEG -100 DEG C., enough of a mineral acid to bring the pH of the mass to between 4 and 7, allowing the acidified mass to stratify into an aqueous phase and an organic phase, separating the two phases, and recovering purified oxime from the organic phase.  In the stratification step, it is desirable to include a water-immiscible organic liquid, such as an aromatic or aliphatic hydrocarbon or halogen-substituted hydrocarbon or a mixture thereof.  The process may be applied to cyclohexanone oxime, especially to compositions containing also 5-30 weight per cent of cyclohexylamine with or without some N-cyclohexylhydroxylamine, such as are obtained by catalytic hydrogenation of nitrocyclohexane in the presence of a hydrogenation catalyst and lead, as described in Specification 860,340.  Sulphuric acid is the preferred mineral acid, but hydrochloric may be used.  The stratification may take place in the range 25 DEG  to 100 DEG C.  The aqueous phase is preferably extracted to recover residual organic material.  The oxime is recovered from the organic phase by distillation, or by extraction and crystallisation.  Where the aqueous phase contains cyclohexylamine, this can be recovered by treating the aqueous phase with at least a stoichiometric amount of a strong base, e.g. sodium hydroxide, and then distilling a water-cyclohexylamine azeotrope from the neutralised mass.  This is distilled with a water-azeotroping inert solvent to obtain a residue of anhydrous cyclohexylamine. Alternatively, cyclohexylamine is recovered from the neutralised mass by extraction with, for example, heptane, benzene or toluene, the p solvent is stripped off and the cyclohexylamine distilled.  Other oximes mentioned are acetoxime and cyclopentanone oxime.
