The azeotropic mixture may have incorporated therein ethylene alycol, N-methyl pyrrolidene or butyrolactone or mixtures thereof. Ionogen salts such as ammonium or lithium nitrate and ammonium thiocyanate may also be added. Examples of suitable amides are dimethyl, diethyl and dipropyl formamide; dimethyl, diethyl, dipropyl and dibutyl acetamide; diethyl and dibutyl propionamide and diethyl butyramide. Suitable organic acids are formic, acetic, propionic and butyric acids.

IPC: H03F1/34
Abstract: 1,084,349. Transistor amplifier circuits. STANDARD TELEPHONES & CABLES Ltd. Aug. 23, 1966, No. 37644/66. Heading H3T. A variable gain amplifier comprises a common emitter stage 1 to which negative feedback is applied by means of a variable resistor 2 in the emitter circuit, and a common base stage 8 connected in a negative feedback path from the amplifier output 11 to the emitter of transistor 1. The high frequency response is determined by a capacitor 25 shunting the collector load of transistor 1 and the low frequency response is determined by capacitor 20 in series with the gain control resistor 2 and also by capacitor 27 in the emitter circuit of the output stage. The values of the amplifier current gain, the feedback resistor 9 and the load resistor 7 are so chosen that variation of resistor 2 effects a linear control. In a modification, Fig. 1 (not shown), the intermediate stage 6A is omitted, and the output stage transistor is the same conductivity type as the input stage transistor.

IPC: G03F7/12
Abstract: 1,095,518. Photo-sensitive materials and processes. EASTMAN KODAK CO. July 28, 1965 [July 28, 1964], No.32151/65. Heading G2C. A light-sensitive composition comprising an organic solvent dispersion of a colloid, an aryl azide and a chlorinated hydrocarbon boiling above 250‹ C. as plasticizer. The colloid is preferably a natural or synthetic rubber which may be oxidized or cyclized and the chlorinated hydrocarbon is preferably an "Aroclor"'(Registered Trade Mark), a chlorinated di- or ter-phenyl, or a chlorinated naphthalene, phenanthrene or anthracene. The composition is coated on to a suitable support (e.g. fibreglass, nylon, rayon, linen, cotton or wool), imagewise exposed and developed with a solution which may contain the plasticizer or be a solution of a butadiene styrene copolymer. Alternatively, the plasticizer may be omitted from the composition and used only in the developer.

Abstract: 1,227,680. Lasers. COMPAGNIE GENERALE D'ELECTRICITE. 16 Sept., 1969 [27 Sept., 1968], No. 45646/69. Heading H1C. [Also in Division H4] A pulse-echo laser range-finder incorporating a photo-multiplier 16 is checked for correct operation by an AND circuit 40 having at least two inputs, one of which is connected to a circuit 8 which supplies a signal when the energy supplied by the laser pumping source is above a predetermined value and another of which is supplied with a signal when the output of a photodiode 15 (receiving a part of the emitted laser pulse) reaches a threshold. Another input to the AND gate occurs when a chronometer 20 reaches the range corresponding to an imaginary target and thereby energizes an electroluminescent diode 25; a fourth input is a signal from a comparator 30 to show that an actual echo pulse has arrived before the maximum capacity of the chronometer is reached. The output of the AND circuit may energize a lamp.

Abstract: 1,228,348. Oxo process; butanols; 2-ethylhexanol. UGINE KUHLMANN. 12 Feb., 1969 [15 Feb., 1968], No. 7605/69. Heading C2C. Butanols are prepared by hydroformylation of propylene in the presence of a cobalt carbonyl using as solvent a mixture of butyl ethers, at least part of which is obtained by catalytic dehydration of butanols formed during the hydroformylation reaction. The dehydration may be effected by heating with metal sulphates or oxides, H 2 50 4  or H 3 P0 4 . The butyl ethers facilitate the recovery of the catalyst as cobalt tetracarbonyl hydride salts formed by alkali treatment by reducing the solubility thereof in the organic reaction medium, allowing them to be extracted with water. The above process may be built into a process for the preparation of 2-ethylhexanol in which after removal of the catalyst, isobutanal is distilled off and the residue treated with alkali to convert n-butanol by an aldolizing-crotonizing reaction into 2-ethylhexenal (and also to hydrolyse butyl formates present as by-products to butanols); the resulting mixture is catalytically hydrogenated to convert the ethylhexenol to 2-ethylhexanol; the product is then distilled to separate an azeotropic mixture of butanols and butyl ethers (which is then dehydrated to convert the butanols to butyl ethers) from a mixture of ethylhexanol and butyl ethers which is further distilled to separate the constituents thereof; the butyl ethers from the aforesaid conversion and those from the aforesaid further distillation are used at least in part as solvents in a further hydroformylation of propylene.

Abstract: 1,229,243. Engraving; printing surfaces. CROSFIELD ELECTRONICS Ltd. 28 May, 1969 [29 May, 1968], No. 25787/68. Headings B6C and B6J. [Also in Division H4] An intaglio printing plate is formed from a metal blank 10, Figs. 2, 3, by forming e.g. by etching therein cells 11 of the maximum depth required, filling them with a solid material 12 such as polythene, glass or antimony, and scanning the surface of the blank with a laser beam modulated in accordance with the image to be engraved, so as to remove material 12, which is more easily evaporated than the metal, to varying depths, Fig. 2, or, where the filling material is harder near the walls of the cell, to varying depths and areas, Fig. 3. This differential hardening can be achieved chemically by causing catalytically accelerated hardening around the cell edges of an epoxy resin based filler, or by applying a cold thermosetting resin to a heated etched surface so as to get differential curing. Alternatively the cells can be partially filled with hard material and filling completed with a softer material. A photo-multiplier on an analysing head 36, Fig. 4, is exposed to light through a prism 30 and an original transparency on a cylinder 20, the head 36 and prism 30 being reciprocated axially of the cylinder while the latter rotates to scan the transparency. The output from the multiplier is passed through a tone or colour correction computer 50 to a laser modulator in a head 46 which moves with the head 36 to scan the blank 10 on a rotating cylinder 22 and selectively remove the material 12. The cylinder scanner may be replaced by an oscillating table scanner.
