Abstract: 1278737 Polyglyidyl ethers SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ NV 8 June 1970 [10 June 1969] 27501/70 Heading C3B Polyglycidyl ethers of polyhydric phenols are prepared by a three step process: (i) epichlorohydrin (I) is reacted catalytically with polyhydric phenol (II) in a molar ratio of at least 1.5 : 1 (I : II), in a substantially anhydrous medium until at least 5% (preferably at least 80%) of the phenolic OH groups have been etherified, (ii) the product is dehydrochlorinated with 0À80-0À99 equivalents of alkali per equivalent of II in the presence of excess I during which water is azeotropically distilled, (iii) remaining I is distilled off in the presence of excess alkali in relation to the quantity of saponifiable chlorine still present. II may be bisphenol A. Suitable catalysts for the first stage are tertiary amines, tertiary phosphines or organic sulphides, or quaternary ammonium, phosphonium or sulphonium compounds, e.g. tetramethylammonium chloride. From 0À5-5 mol. per cent of catalyst may be used based on the phenol. The reaction temp. in the first stage may be 90- 130‹ C. In the second stage an aqueous soln. containing at least 45% by wt. NaOH or KOH may be used in the third stage a 2-20% by wt. alkaline soln. may be used to provide a 5-15 fold excess of alkali. Excess I may be removed under vacuum at 100-180‹ C. The by-product salt may be removed by dissolving the resin formed in an inert solvent and washing with water. Alternatively it may be removed by filtration or centrifuging. The products are low mol. wt., e.g. products from bisphenol A have epoxide equivalents of 182-198.

Filed: 1947-10-14
Abstract: 631,639. Automatic change-speed gearing. STIEGER, H. J. Oct. 14, 1947, No. 27554. [Class 80 (ii)] A low-power change-speed chain gearing for use on motor-cycles, delivery trucks, and low-power industrial engines comprises a first centrifugal clutch to engage low gear on the engine being sufficiently accelerated and a second centrifugal clutch to engage a higher gear with over-running of the first gear when a higher speed is attained. As 'shown, torque is applied to a dog clutch 20 and on engine acceleration the portion 21 of the first clutch a moves radially to frictionally engage its drum 24 which in addition to driving a shaft 23 conveys the torque through a one-way driving device 25, 26 to a sprocket 27. A chain on this sprocket drives a double sprocket 30 which directly or through epicyclic reducing gearing drives the driven shaft 31. The sprocket 30 also drives a sprocket 34 secured to the member 36 of the second centrifugal clutch b whose drum 38, secured to the shaft 23, is engaged on higher speed being attained and which drives the driven shaft 31 with over-running of the one-way driving device 25, 26. In a modification both clutches operate on the same drum and reduction gearing may be introduced employing double or treble chains. The addition of a third centrifugal clutch with a one-way driving device will produce three speed changes.

Filed: 1973-06-14
Abstract: 1439654 Photo-electric receivers COMPUTER TRANSMISSION CORP 14 June 1973 [19 June 1972] 28368/73 Heading G1A An input circuit for optically sensitive receivers comprises a series combination of a photodiode and a first resistor; means for applying a p.d. across the series combination; amplifier means having its input connected to the junction between the photodiode and the first resistor; and a second resistor coaxially surrounding the first resistor and coupled to the output of the amplifier means. A photodiode 10 in series with a first resistor 21, typically 10 megohms, is connected to a positive supply 30, via resistors 26, 25, the latter forming the drain load of an input FET 23. Coaxially surrounding the first resistor 21 is a second resistor 22, typically 500 ohms, connected in a bootstrap circuit via a capacitor 41 to the drain electrode of the FET 23 which is made to follow the potential variations of the source 31 by being coupled to the emitter of a transistor .32 driven by the source 31. The voltage gain from the first resistor 21 to the second resistor 22 is typically 0.98, whereby the effective amplifier input capacitance is substantially reduced and the bandwidth improved. The bandwidth may be further extended by a transistor 42 having a capacitive emitter impedance 44 and an inductive collector load 43. The coaxial resistors 21, 22 of substantially equal length L may be of deposited carbon or wirewound on ceramic bases to give uniform respective resistance per unit length. The ratio of length L to outer diameter D should be at least two, preferably four. The end caps 21a, 22a are mutually isolated, while the end caps 21b, 22b may be inter-connected for common earthing. A component layout at the rear of a shielded optical receiver is described Figs. 5, 6 (not shown).
