Abstract: 1,264,592. Cycloalkenone esters. L. GIVAUDAN & CIE S.A. 10 March, 1970 [10 March, 1969], No. 11335/70. Heading C2C. The invention comprises cycloalkenone esters of the formula in which R is a hydrogen atom or an alkyl, alkenyl, or alkynyl group having up to 8 carbon atoms, R 3  is an alkyl group having up to 8 carbon atoms and n is 1 or 2, except that when n is 2, R is not hydrogen or methyl. These esters can be obtained by reacting an enol ether of general formula in alkaline, anhydrous reaction medium with a compound of formula CH 2 (COOR 2 ) 2 , in which R 2  is an alkyl group having up to 8 carbon atoms. The preferred alkaline anhydrous medium is a solution of an alkali metal alcoholate in the alcohol and when such an alcoholate is used the group R 3  in the product will correspond to the alkyl radical of the alcohol due to transesteriflcation. The esters formed may be used as intermediates in the production of odorants. For example [2-(2<SP>1</SP>-pentynyl)-3-keto-1-cyclopenten-]-yl acetic acid methyl ester may be catalytically hydrogenated using a Lindlar catalyst and subsequently hydrogenated using lithium in ammonia to give methyl jasmonate, i.e. [2-(2<SP>1</SP>-pentenyl)-3-keto-1-cyclopent-]-yl acetic acid methyl ester. [2-Pentyl-3-keto-1-cyclopent-]-yl acetic acid methyl ester may be obtained by hydrogenation from [2-pentyl-3-keto- 1-cyclopenten-]-yl acetic acid methyl ester. The latter ester may also be saponified and product decarboxylated to give dihydrojasmone. Examples are given of the preparation of (a) [2 - (2<SP>1</SP> - pentynyl) - 3 - keto - 1 - cyclopenten]-yl acetic acid methyl ester; (b)[2-methyl-3-keto-1- cyclopenten]-yl acetic acid methyl ester; (c) [2-pentyl-3-keto-1-cyclopenten]-yl acetic acid methyl ester which is hydrogenated to give methyl dihydrojasmonate; (d) [2-hexyl-3- keto- 1-cyclopenten]-yl acetic acid methyl ester; (e) [2 - allyl - 3 - keto - 1 - cyclohexen] - yl acetic acid methyl ester; (f) [2-octyl-3-keto-1-cyclopenten]-yl acetic acid methyl ester; (g) a mixture of [3 - keto - cyclopenten] - yl acetic acid methyl ester and [3-keto-1-cyclopenten]-yl malonic acid dimethyl ester and (h) 2-allyl-3- keto-cyclopenten-1-yl methyl acetate.

Abstract: 1,266,657. Coating process. C. T. Mc- ELROY. 12 June, 1970, No. 28549/70. Headings B2E and B2L. A process for coating a surface of a cellulosic panel, especially a plywood panel, consists in applying to the surface a resinous chemical coating free of combustible solvents and suspended or dissolved in water while the panel is in constant linear movement, directly impinging an open flame upon the coating to boil off some of the water vehicle and singe some of the surface filaments, flattening the partly dried coating under pressure usually by means of rollers, repeating the flame impingement and flattening operations and then repeating these operations again, the third open flame being at approximately 1400F and the first and second flames usually alsobeing at this temperature. The coating may be a polyvinyl acetate emulsion, vinyl acetate copolymer latex or solution, vinyl acrylic copolymer latex, a water-miscible alkyd resin, water-soluble lacquer or urea-formaldehyde resin, a hydrosol system or aqueous thermosetting polymer solution. If thermosetting polymer is used, two or more additional flame and flattening stages may be used to effect curing. Apparatus for effecting the process comprises driven support rollers for the panel 17, a rubber applicator roller 16 in contact with a knurled doctor roller 15 for applying the coating. a burner 19 to provide the open flame, a polished steel smoothing roller 21 which is heated to 550-600F, and further burners 19a &c. and smoothing rollers 21a &c. The smoothing rollers may rotate at a speed less than the linear speed of the panel to minimise collection of the coating material on the roller.

Abstract: 1290637 Semi-conductor devices HONEYWELL Inc 1 June 1971 [29 June 1970] 18363/71 Heading H1K A plurality of diffused regions 10 is provided at various locations in a semi-conductor body between which locations the composition of the body varies so as to produce differing energy gaps. The PN junctions between the regions 10 and the body thus exhibit peak photovoltaic responses at different wavelengths, enabling the device to be used as a radiometer for measuring the temperature of a source without the emissivity of the source or the transmission of the intervening space being known. A common contact 14 is attached to the body and separate contacts are provided on each region 10. When the regions 10 are all formed in the same surface 11 of the body, as shown, the radiation may be arranged to fall on either of the major surfaces 11, 15 or on an end surface as indicated by arrow 13. In the case illustrated the device may be made self-filtering by arranging for the largest energy gap within the body to occur at the illuminated face, so that the higher energy light is filtered out before the lower energy gap compositions are reached. Diffused regions may alternatively be provided on opposite major surfaces of a body which is illuminated from one edge. The semi-conductor material may be Hg 1-x Cd x Te or lead tin telluride, the necessary composition gradient being obtained by controlled ingot growth, epitaxial deposition, vapour transport or interdiffusion. Control of the temperature at which the device operates, e.g. by means of a thermoelectric cooler, provides another means of adjusting the response of the device, since each junction will have a different temperature dependence of energy gap and hence of peak response wavelength. A prior art device is described (Fig. 1, not shown) which comprises two photo-conductive bodies of different composition, and hence different peak response wavelength, mounted one on the other by a transparent glue or assembled by epitaxial deposition of one body on the other.

Abstract: 1316420 Colour television EMI Ltd 1 Dec 1970 [16 Dec 1969 16 Jan 1970] 61127/69 and 2141/70 Heading H4F The invention concerns the automatic registration of trains of video signals corresponding to different colour components of a common scene scan by a plurality of camera tubes. R and G colour signals are supplied to terminals 1, 2 and signals derived from outline generators 4, 5 indicate the presence of edges on the respective signal trains. An error detector circuit 7 including a series of logical AND and OR gates, inverters and a flip-flop (see Fig. 3, not shown) extracts a correction signal based upon the misregistration of edges in the R and G signal trains, and applies it, via an integrator 8, to a line correction output terminal 9. Misregistration in the frame direction is also corrected by means of a slope detector circuit 10 (see Fig. 6, not shown, for details) which determines the sign of the slope of any sloping lines in the video image by measuring the misregistration of edges in the G signal train applied to terminal 2 with those in G D  signal train, being the G signal train delayed by one line interval. The line correction signals from the error detector 7 are then used, via a steering circuit 11 controlled by the output of the slope detector 10, to produce frame-direction misregistration correction signals at terminal 13. The line and frame shift circuits to which the correction signals are applied are also provided with manual adjustment means to enable initial registration to be set up. The blue colour component signal and the luminance may be registered with the other colour signals by means of similar circuitry.

Abstract: 1343162 Electrolytic etching to form an extruder screw IMPERIAL CHEMICAL INDUSTRIES Ltd 20 June 1972 [27 July 1971] 35205/71 Heading C7B [Also in Division B5] By an electrolytic etching method is formed an extruder screw suitable for the continuous extrusion of thermoplastic polymeric materials. The method includes applying to the surface of a metallic rod of substantially circular crosssection a masking resist in a configuration corresponding to that of the land pattern of the screw, and subjecting the masked rod, as anode, to the action of an electrolytic solution traversed by an electric current from a cathode. The rod anode may be of steel (e.g. mild, low alloycarbon-, or silver-steel) or of alloy based on Fe, Co, Ni or Co- Cr. It may be precleaned by a solvent and by abrading. The mask may be tape, paint, wax or a photo-resist. The cathode may be of stainless steel and may be a rod of circular, square or polygonal crosssection. More than one cathode may be placed around the rod anode or the anode may be placed within a tubular cathode through which the electrolytic solution is pumped. The electrolyte may be filtered. The anode may be rotated. The electrolyte may be of Na or K halide, nitrite or nitrate e.g. Na Cl + HCl. The electrolysing current may be D.C. (e.g. 5-20 volts, 10-30000 amps and 0À5-5 amps/sq cm at the anode) or may be A.C. By appropriate masking, screws can be produced (i) having along their length full or interrupted flights and constant or variable pitch and (ii) having at their drive end a key way system of splined shank. The root diameter at zones along the length of a screw can be controlled either (a) by varying the time for which the respective zones are subjected to electrolysis or (b) by varying the current density at zones along the screw length, e.g. by providing insulated sleeve(s) around zone(s) of the cathode. A screw having an eccentric root diameter is produced by using an auxiliary anode on the opposite side of the masked anode rod from the cathode (Example 2). On completion of the electrolytic etching, the masking resist is removed and the screws may be subjected to grinding and polishing or to nitriding and polishing.
