Title: Process for the introduction of alkyl, aralkyl or cycloalkyl groups onto a functional group-substituted carbon chain
Inventor: BOUISSET MICHEL
IPC: C07C51/353
Filed: 1980-12-05
Abstract: Process for introducing a substituent selected from branched- or straight-chain alkyl radicals having from 1 to 12 carbon atoms, aralkyl or cycloalkyl radicals in which the alkyl moiety has from 1 to 4 carbon atoms, into a carbon chain bearing a stable functional group the said carbon chain having at least one proton in  alpha -position in relation to this functional group, process whereby, in a first step, this carbon chain is reacted with a complex base comprising a mixture of alkali metal amide and alkali metal alcoholate suspended in an anhydrous organic solvent to provide temporarily a carbanion, then in a second step this carbanion is reacted in an anhydrous organic solvent with an alkyl, aralkyl or cycloalkyl halide corresponding to the substituent to be introduced.

Abstract: Heat can be recovered by biological generation of heat upon aeration of refuse, such as garbage or sludge, in an aeration vessel (11) by introducing oxygen-containing gas, such as air, in a closed cycle (11, 33, 31, 35) to thereby enrich gas withdrawn from the vessel with the oxygen, typically by reintroduction of gas withdrawn from an upper gas portion (43) of the vessel, after introduction of additional oxygen, for example controlled by a valve (65) into a lower portion of the contents of the aeration chamber. Control can be effected automatically, by a control unit (55, 55') through a valve (51, 51') or manually; automatic control can be effected, for example, by sensing oxygen or carbon dioxide concentration by suitable sensors (57, 59) within the vessel. To permit recovery of methane of high quality in a subsequent decomposition and methane recovery container, material withdrawn from the aeration vessel is degassed in degassing chambers (68; 69, 70), for example by storage for about 1/2 hour, and venting of emanating gases. Control of valves regulating flow from, and to, the aerating vessel and the degassing chambers (69, 70) permits preheating of freshly introduced refuse by the material withdrawn from the degassing chambers in a counterflow heat exchanger (17'), while preventing possible escape of non-aerated substances from the vessel (11) by isolating the aeration vessel (11) during introduction of new refuse, and emptying only a chamber (e.g. 69) of said degassing chamber system (68).

Abstract: The input circuit (10) includes a rectifier (12) for converting a sensed a.c. voltage which is supplied through a coupling impedance (20) to the light emitter (28) of an optical isolator (30). While the a.c. voltage is below a first predetermined voltage, a switchable low impedance circuit path (46, 48) in parallel with the light emitter is rendered conductive to maintain a low voltage across the light emitter to prevent it from becoming conductive until the sensed a.c. voltage reaches the predetermined voltage. A switchable high impedance circuit path (52, 54) in parallel with the low impedance circuit path (46,48) becomes conductive once the a.c. voltage reaches the first predetermined voltage to place a high voltage across the light emitter (28) to exhibit a sharp "turn-on". The high impedance circuit path (52, 54) remains conductive to keep the light emitter (28) energized until the a.c. voltage drops to a second predetermined voltage so that the light emitter exhibits a sharp "turn-off".

Abstract: In a control valve for the metered filling of liquid or pasty media, having a valve housing (1) and a control piston (2) displaceably mounted in the latter in the direction of its longitudinal axis, the valve housing (1) contains a control chamber (3) arranged between a filling material inlet (5) and a filling material outlet (4) oriented in the direction of the longitudinal axis of the control piston (2), which chamber can be closed to the filling material inlet (5) by means of a valve and to the filling material outlet by means of two valves arranged at a distance from one another, each valve being formed from a cylindrical part (10, 11, 12) of the control piston (2) and a cylindrical surface (6, 7, 8) disposed coaxially with respect to the axis of the control piston (2). The valves arranged between the control chamber (3) and filling material outlet (4) are distinguished in that the distance (a) between the limiting edges of the cylindrical part (11, 12) of the control piston (2) which face the control chamber (3) are greater than the distance (b) between the limiting edges of the cylindrical surfaces (7, 8) of the housing (1) which are remote from the control chamber. This prevents a pressure build-up in the prechamber (9) situated between the two valves, and thus a spraying of the filling material at the filling material outlet (4) when the control piston (2) is displaced in the direction of the filling material outlet (4).   <IMAGE>
