Title: Derivatives of 2,3-dihydro-1,4-oxathiin and processes for their preparation
IPC: C07D327/06
Filed: 1966-04-12
Abstract: The invention comprises 2,3-dihydro-1,4-oxathiin compounds of the formula <FORM:1099244/C2/1> where X is a carboxylic or a carboxamido group. The carboxamido derivatives may be obtained by mixing an x-halo-N-substituted acetoacetamide with 2-mercaptoethanol, generally in an inert common solvent, in the presence of a base, and acidifying the resulting product so that it cyclizes with loss of water to form the oxathiin. The carboxylic acid derivative may be obtained by mixing a C1-4 lower alkyl x-haloacetoacetate with 2-mercaptoethanol, generally in an inert common solvent, in the presence of base, acidifying the resulting product so that it cylizes to form an alkyl ester of 2,3-dihydro-5-carboxylic acid - 6 -methyl - 1,4 - oxathiin and hydrolysing the ester to the acid.  The amide derivative of the latter acid may be obtained by forming the acid halide thereof and reacting the halide with ammonia or an amine.  Many examples are given including those in which the substituents on the nitrogen atom of the carboxamido group are hydrocarbon and heterocyclic groups, and hydrocarbon substituted by, e.g.,halogen, nitro, carboxyl, ether, ester and cyano groups.

Abstract: 425,031. Variable - speed gearing. CASSAGNE, G. R., Pavillon le Bouvreuil, Avenue Guynemer, Cazaux, Gironde, France. June 2, 1933, Nos. 16052 and 16053. Convention dates, Feb. 8 and March 27. [Class 80 (ii)] [See also Groups XXVII and XXXIII] Relates to an epicyclic gear for aircraft or motor vehicles of the kind which is only operative when a part thereof is retarded or stopped by means for charging or supercharging the engine. The engine shaft 1, Fig. 1, drives through gears 2, 3 the carrier 5, 6 of stepped planets 10, 11 meshing respectively with a gear 25 on the propeller shaft 27 of an aeroplane and a gear 26 on a shaft 25 which drives the engine supercharger compressor. The drive is thus divided between the shafts 27, 28 so that the engine may be operated under optimum conditions at different loads or altitudes. The shafts 14 of the planets 10, 11 carry clutch members 15 adapted to be gripped between clutch members 16 on the carrier 5, 6 and members 17 carried by annular thrust-bearings 22 displaceable axially by arms 18 screwed to rods 19 rotatable in synchronism by a toothed ring 24. On engaging the clutches, the shafts 14 are locked and the epicyclic part of the gearing and the shafts 27, 28 rotate solid, only the reduction of the gears 2, 3 being obtained. In a modification for driving motor vehicles, the arms 18 are operated by eccentrics and a brake is provided for the shaft 27. The vehicle may be controlled by regulating the admission to and the delivery of air from the supercharger compressor. In a further modification, the propeller shaft 27 carries an internally toothed wheel gearing with the planets 10. The Specification as open to inspection under Sect. 91 describes the following subjectmatter. In Fig. 9 (Cancelled) single planets 65 are employed which mesh with an internal gear 61 on the driven shaft 27 and with a sun 66 on a sleeve 67 connected through a planetary gear 68, 69, 71, 73 to the compressor shaft 28. It is stated that by sliding the internal wheel 71 so that its friction faces lock it to the planet carrier 73 or to the fixed casing forward and reverse drives respectively may be obtained. In a further arrangement with stepped planets, the engine is connected to the shaft 28 and the compressor to the shaft 1. This is also the case in Fig. 11 (Cancelled), the shaft 1 being connected by a clutch 85 to the compressor shaft 88, or to a fixed member 87 to give a reverse drive. This subjectmatter does not appear in the Specification as accepted.

A container formed by a cavity b (Fig. 1) in a water-bearing rock or concrete, in which oil or like liquid lighter than water is stored in direct contact with a portion of the cavity walls and on a water bed 8 held in balance by a water column 9 so that the oil level is substantially independent of the subsoil water level, comprises means such as a pipe 10 for withdrawing oil from the container and means for adjusting the height of the water column and therefore the oil level so that said portion of the cavity walls is everywhere subjected to a subsoil water pressure which is greater than the oil pressure and the water column pressure at the same level. A fluid-tight lining 2 of concrete or sheet metal is provided at the top of the cavity. Thus, in the lower part of the cavity, the subsoil water pressure indicated by the line g is greater than the oil pressure within the container filled to the level ho2 indicated by the line o2 and the pressure in the water column 9 below the level hv2 indicated by the line v2. A space is left between the fluid-tight lining and the rock which may be supplied with water to raise the subsoil water level. In the form shown in Fig. 2 the fluid-tight lining is in the form of a narrow winze 2 and the water bed 8 communicates with a large water surface hv via pipes 9 and 9a and/or a horizontal funnel 24 and bore 25. The subsoil water pressure at the upper part of the cavity is raised by one or more shielding holes 23. In another form, a fluid-tight cover is fitted at the bottom of 'the winze and water is supplied to the space above the cover from whence it is fed to the water bed, the space thus acting as a buffer. The cover may be slightly permeable to water to protect it from damge by the oil. In further forms, the space in the winze above the cover may .be used for heating the oil before removal, an automatic pump may be used to remove water from the water bed as subsoil water leaks -in and the exposed rook surrounding the winze may be roofed over and water under pressure supplied to the space between the roof and the rock to maintain the subsoil water pressure at a high level.

Abstract: 748,609. Change-speed gear; friction clutches. DAIMLER-BENZ AKT.-GES. June 18, 1953 [June 20, 1952], No. 16859/53. Class 80(2) [Also in Group XXIX] A hydraulic coupling having a friction clutch 36 arranged substantially within its inner radius and in communication with its working liquid space has discharge means arranged for automatically determining or controlling the liquid level in the rotating coupling in such a manner that the coupling is substantially filled but the friction clutch is free of liquid at least when it is disengaged. The impeller 12 is driven by an input shaft 10 and the turbine 14 is connected to a shaft 18 which drives the output shaft 28 through change speed gearing, or alternatively is coupled directly to the shaft 28 by means of the clutch 36 part of which is connected to the impeller 12 while the other part is connected to a forwardly extending part of the shaft 28. The impeller has discharge ports 44 which communicate with a chamber 43 into which extends a discharge member 45 which communicates through a bore 46 in the shaft 28 with bores 46<SP>1</SP> in one of the change speed gears 26 and a reservoir formed in the coupling housing. A pump 16 driven by the member 12 supplies oil from the reservoir to the coupling. Relative rotation of the pipe 45 depends on the gear ratio in use and hence the filling of the coupling depends on the gear ratio. The length of the pipe 45 is arranged so that the clutch members are free from oil in the lower gear ratios. The discharge member 45 forms part of a vibration damper connecting the clutch part with the shaft 28. In a modification the coupling precedes a planet gear and the carrier is combined with return pipes for the oil flowing to the reservoir. In a further modification, the coupling preceeds an infinitely variable friction gear and the friction roller carrier is provided with radial bores to serve as return pipes. The outer ends of the discharge member 45 may open radially or be directed against the flow.
