The invention relates to a process for the manufacture of polyene compounds of a general formula in which the R-symbols have the same significance and each represents the 2-[4-hydroxy- 2,6,6 - trimethylcyclohex - 1 - en - 1 - yl]- vinyl, the 2 - [3 - hydroxy - 2,6,6 - trimethylcyclohex - 1 - en - 1 - yl] - vinyl or the 2- [3 - oxo - 2,6,6 - trimethyl - cyclohex - 1 - en- 1 - yl] - vinyl residue, which process comprises reacting the dialdehyde of the formula with a phosphonium salt of the general formula in which Y is an alkyl or di-(lower alkyl) amine group and Z is a halogen or hydrosulphate ion, in the presence of an ethylene oxide which may be substituted by C 1 -C 4  alkyl. Examples are described in which 2,7-dimethylocta-2,4-6-trien- 1, 8-dial is reacted with (a) [5-(4-hydroxy-2,6,6- trimethyl - cyclohex - 1 - en - 1 - yl) - 3 - methylenta - 2,4 - dienyl] - triphenyl - phosphonium bromide; (b) [5 - (3 - hydroxy - 2,6,6 - trimethyl - cyclohex - 1 - en - 1 - yl) - 3 - methylpenta 2,4 - dienyl] - triphenyl - phosphonium bromide; and (c) [5 - (3 - oxo - 2,6,6 - trimethylcyclohex - 1 - en - 1 - yl) - 3 - methyl - penta- 2,4 - dienyl] - triphenyl - phosphonium bromide. These phosphonium salts of Formula II are prepared respectively by (a) 4-(4-acetoxy-2,6,6- trimethyl - cyclohex - 1 - en - 1 - yl) - 2 - acetoxybut - 3 - yne is reduced to 3 - hydroxy - betaionol with the aid of a mixed metal hydride, which is then oxidized and the 3-hydroxy-betaionone thus obtained is then reacted with vinyl magnesium bromide to produce 5-(4-hydroxy- 2,6,6 - trimethyl - cyclohex - 1 - en - 1 - yl) - 3- methyl - penta - 1,4 - dien - 3 - ol which is reacted with triphenyl-phosphonium bromide; (b) Beta-ionone is reacted with ethyl orthoformate and the resulting ionone enol-ether is treated with a brominating agent and the 4- bromo-beta-ionone thus obtained is subsequently acylated and the resulting 4-(3- acetoxy - 2,6,6 - trimethyl - cyclohex - 1 - en- 1 - yl) - but - 3 - en - 2 - one - [4 - acetoxy - beta - ionone] is reactedwithvinyl-magnesium bromide, hydrolised and converted into [5-hydroxy-2,6,6- trimethyl - cyclohex - 1 - en - 1 - yl) - 3 - methyl penta - 2,4 - dienyl] - triphenyl - phosphonium bromide by treatment with triphenyl-phosphonium bromide; and (c) the 5-(3-hydroxy- 2,6,6 - trimethyl - cyclohex - 1 - en - 1 - yl)- 3 - methyl - penta - 1,4 - dien - 3 - ol is oxidized and the resulting 5 - (3 - oxo - 2,6,6 - trimethyl. cyclohex - 1 - en - 1 - yl) - 3 - methyl - penta- 1,4 - dien - 3 - ol is subsequently converted into [5 - (3 - oxo - 2,6,6 - trimethyl - cyclohex- 1 - en - 1 - yl) - 3 - methyl - penta - 2,4 - dienyl]- triphenyl - phosphonium bromide by treatment with triphenyl-phosphonium bromide.

Abstract: 1,264,719. Electrophotographic materials. FUJI PHOTO FILM CO. Ltd. 17 June, 1970 [18 June, 1969], No. 29393/70. Heading H1K. [Also in Division C1] An electrophotographic material has an electroconductive backing bearing a resin-bound layer of zinc oxide prepared by heating zinc hydroxide or basic zinc carbonate in the presence of water and under elevated pressure. Typically, the hydroxide or carbonate is autoclaved with water at 250‹ or 300‹ C. and under a pressure of 200-300 atmospheres for 1À5-2 hours, though an example using the hydroxide uses a pressure of 2À2 atmospheres and a time of 15 hours. In an example the hydroxide is made by the preparation and hydrolysis of a sodium zincate solution. The prepared oxide in the examples is washed and then dried at (100‹), 120‹, or 160‹ C. for (12), 20, or 12 hours. An example has the oxide dispersed (with cobalt naphthenate) in a styrene-modified alkyd resin and carried by electroconductive paper. Alternative binders are copoly-(vinyl chloridevinyl acetate), copoly-(styrene-butadiene), and silicon, epoxyester, alkyd and acrylic resins. The material may also contain plasticizers, inert pigments, lubricants, surfactants, dye sensitizers, and French process zinc oxide.

Abstract: 1296288 Automatic flow control LEYBOLDHERAEUS - VERWALTUNG GmbH 19 April 1971 [14 March 1970 26 Feb 1971] 23970/71 Heading G3R [Also in Divisions C7,H1] The rate of production of droplets of molten metal is measured by a counter comprising a light source 33, a detector 35 and an evaluating device 38. The latter compares the measured rate with a precribed reference rate and reports any differences to controllers 26 and 23 which then vary the power and/or direction of the appropriate electron beams playing on the surface of the molten metal in the container 10. This causes local changes in the viscosity of the pool 12 of molten metal and thus changes the rate of production of the droplets of metal. The container 10 may be provided with more than one dripping trough 17 and with an electron gun 25 which cyclically sweeps the zone of molten metal near each trough. In this case the controller 26 ensures that the relative residence times of the focused electron beam at each dripping trough 17 are such as to ensure a uniform dripping rate from each trough. The evaluating device 38 may integrate the pulses received from the detector 35 over a period of time

Abstract: 1307115 Determining temperature distribution RANK ORGANISATION Ltd 19 May 1971 [20 May 1970] 24416/70 Heading H4F In an infra-red to visible light transducer scanning system each point on the original scene is detected several times over to give video signals containing a constant "real signal" component and a varying noise signal component. The noise components are reduced or cancelled out by forming the average of the video signals and the average signal is used to form a display at a necessarily reduced scanning rate. Video signals, from the infra-red camera A, Fig. 1, scanning at a high frame frequency, are fed to AND gates 12. Start of line and frame pulses are generated by means 1 and 2 and fed to unit 3 which selects that line at which the averaging process is to start, to give a pulse which sets bi-stable 4 and passes, via OR gate 5 to delay 9. Set bi-stable 4 enables AND gate 7 to pass the line pulses to counter 6. The counter has one output 6A for each line to be averaged and enabling pulse are fed in succession to AND gates 8. The delay X, Fig. 2, of means 9 determines at what point along the lines the averaging is to commence. A further delay Y is introduced by means 10, this delay being constant for the number of frames over which the averaging is to take place and then increasing by an increment Z. The delayed pulse passes via gate 8 to gate 12 such that the video signal sample thereat is passed to averaging filter 13. The output of each "line filter" 13 is fed to a respective scribing means of a recorder and/or to a display table 14.
