Title: Process for preparing 1-ethynylcyclohexanol and homologues
Filed: 1958-09-12
Abstract: 1-Ethynyl-cyclohexanol and alkyl derivatives thereof are prepared by passing acetylene under superatmospheric pressure into a homogenous liquid mixture comprising (i) cyclohexanone and/or one or more alkyl-cyclohexanones, (ii) an auxiliary solvent for acetylene such as a lower alkanol, and (iii) a strongly basic ethynylation catalyst such as caustic potash, sodium methoxide or benzyl trimethyl ammonium hydroxide, the temperature of the liquid mixture being maintained below 30 DEG C. so that at least one mole of acetylene is dissolved therein per mol of cyclohexanone; and then heating the solution under pressure to a temperature of about 100 DEG C. to 170 DEG C. at which the dissolved acetylene and the cyclohexanone react to form the desired ethynyl cyclohexanol.  The pressure in the heating zone is maintained at 1,000 to 5,000 p.s.i.g. to ensure that the acetylene remains in the liquid phase during the reaction.  In Example 1, cyclohexanone (294 parts) is added to a solution of KOH in methyl alcohol; and acetylene (143 parts) is then absorbed in the solution at a pressure of 300 p.s.i.g. and the temperature of 7 DEG C.  This mixture is then passed through a tubular reactor at 135 DEG C. and a pressure of 1,500 p.s.i.g.  The reactor-effluent is degassed and then flash distilled at a temperature of 100 DEG C and a pressure of 0.3 mm.  The flash-distillate is fractionated under reduced pressure to separate 1-ethynylcyclohexanol.  The distillation-bottoms are recrystallized from carbon tetrachloride to obtain 1,2-bis(cyclohexanol-1)ethyne.  Examples 6 to 9 relate to the preparation of 1-ethynyl-3-methyl - cyclohexanol, 1 - ethynyl - 2 - methyl - cyclohexanol, 1 - ethynyl - 4 - tert. - octyl - cyclohexanol, and 1 - ethynyl - 3, 3, 5 - tri - methyl-cyclohexanol, respectively.

Abstract: 1,046,559. Pulse handling circuits. WAYNE KERR CO. Ltd. June 16, 1965 [July 22, 1964], No. 29605/64. Headings H3P and H4D. Pulses are produced in a particular phase relationship at half the difference frequency of two input signals by additively combining the signals, passing them through a peak detector and amplitude discriminator to give an output when the peak exceeds a certain level, and adjustably delaying the output, means being provided for suppressing one of the two pulses which may occur in one cycle of the difference frequency, or bringing two such pulses into time-coincidence with one another. Fig. 1 shows such an arrangement in a ground monitor receiver for an I.L.S. system as in Specification 1,046,558, for automatic control of the I.L.S. transmitter, but the arrangement can also be used in an aircraft receiver. Fig. 1 shows an I.L.S. receiver as in Specification 1,046,558, with the addition of components 40-45. The received 90 c/s. and 150 c/s. signals are passed to a peak detector 41 which provides a D.C. signal proportional to the peak amplitude of the combined signal (which depends on the relative phase of the 90 c/s. and 150 c/s. components). This D.C. signal is compared with the combined signal in the unit 42 and only the tips of the waveform which exceed the D.C. signal level are allowed to pass. By means of the phase adjuster 40, this can be arranged to occur only once per cycle of the 30 c/s. signal, and can be set at any desired point by an adjustable delay 44. The differentiated output from 45 is used to synchronize the frequency divider 26. In an alternative arrangement (Fig. 2, not shown) the phase adjuster 40 is omitted, and the amplifier 43 includes a paralyzing delay circuit so that if two pulses appear during one cycle of the 30 c/s. signal the second one will be suppressed.

[Also in Division F2] In a closure arrangement for a pressure vessel 10 wherein a closure 13 is retained in the end of the vessel against outward movement under the action of internal vessel pressure by a plurality of arcuate locking segments 16 held in engagement with the vessel wall by spacers 20 interposed between the locking segments and an axially-extending cylindrical end projection 15 of the closure, each segment is provided with a plurality of arcuate lands 18 arranged to engage in a plurality of annular grooves 16 in the vessel wall. The lands and grooves may be of triangular or rectangular cross-section, Fig. 2 (not shown). Sealing between the vessel and closure is effected by a ring 23 extending around the inner end of the closure and clamping radially spaces inner and outer gaskets 27 and 24 against the closure and vessel wall. The ring 23 is initially drawn axially against the closure to compress said gaskets by bolts 30 extending through radially elongated slots 32 in the locking segments, said slots permitting radial disengagement of the segments from the vessel wall, and internal pressure build up in the vessel subsequently acts to urge the ring 23 axially outwards to further compress the gaskets. As shown in Fig. 4, cams 19 may be initially used to urge the segments in locking engagement with annular grooves in the vessel wall, the spacers 20 being subsequently inserted to retain the segments in their locking position.
