Patent GB-864536-A (GB)
Title: ª‡-ethyl-phenylacetylurea
Inventor: GOLD-AUBERT PHILIPPE
IPC: A61K31/17
Filed: 1957-11-06
Abstract: The invention comprises the optically active isomers of alpha-ethyl-phenylacetylurea; and a process for the preparation of alpha-ethylphenylacetylurea which comprises reacting alpha-ethyl-phenylacetyl chloride with urea in the presence of an acid-binding agent and in the absence of a solvent.  The process p is preferably effected at 75 to 150 DEG C. in the presence of 1-phenyl-2, 3-dimethyl- 5-pyrazolone or an alkali metal bicarbonate. When the d- or l-isomer of the acid chloride is used the process leads to the optically active isomers of the invention, and this process may be combined with the preparation of the active acid chlorides by reaction of the corresponding optically active acids with thionyl or sulphuryl chloride.  This process may in turn be combined with the preparation of the active acids by resolution of racemic alpha-ethyl-phenylacetic acid with an optically active base followed by fractional crystallization of the resulting salts and recovery of the optically active acids therefrom.  The preferred active base is cinchoridine and the crystallization is preferably effected in fifty per cent. aqueous ethanol, the d-acid salt of this base being less soluble than the l-acid salt.  The l-isomer is preferably further purified after liberation from the cinchoridine salt by isolation as the codeine salt, from which the acid is again liberated.  Examples are given, and reference is also made to the use of common solvents in the process of the invention.  It is stated that while both the d- and l-isomers of alpha-ethyl-phenylacetylurea have anti-epileptic activity, the d-isomer has an excitive action whereas the l-isomer has a sedative action (see Group VI).ALSO:A composition for the treatment of epilepsy and like conditions, having substantially no sedative, soporific or excitive properties, comprises d-alpha-ethyl-phenylacetylurea together with one or more drugs having a soporific and/or sedative action.  Such a composition is prepared by mixing with the said d-isomer, which itself has excitive properties, just sufficient of a sedative and/or soporific drug substantially to neutralize the excitive properties of the d-isomer.  Such drugs include barbiturates, phenacemide and anti-convulsant drugs such as diphenylhydantoin, and in particular l-alpha-ethylphenylacetylurea, which itself has sedative properties. The compositions of the invention do not include racemic alpha-ethyl-phenylacetylurea, which has excitive properties, or compositions containing it.  Preferred compositions contain the d- and l-isomers in a ratio of 1 : 3 to 1 : 1.25 parts by weight, preferably 30 to 40 parts by weight of the d-isomer to 60 to 70 of the l-isomer.  Reference is also made to the use of the individual d- and l-isomers in the treatment of epilepsy, when they may be combined with a suitable pharmaceutical carrier and made up as tablets, capsules, syrups or elixirs, which may contain flavouring agents, or injection solutions.

Convention date, Dec. 13, 1930. [Class 38 (iii).] In a multi-motor drive. e.g. for a printing- machine, in which the individual driving motors are electrically interconnected to ensure synchronous operation, the driving motors each drive an auxiliary asynchronous machine, and all the auxiliary asynchronous machines are electrically coupled on their stator and rotor sides, but are energized only over that speed range in which the synchronizing effect of the connections between the driving motors is small. With asynchronous driving motors the auxiliary asynchronous machines are energized only during high speed operation The auxiliary machines may have a different number of poles from that of the driving motors, and may rotate in opposition to their fields. The drum controller used for varying the starting and speed regulating resistances may also act directly or through a relay, to connect the auxiliary machines to the supply for positions corresponding to medium speed up to high speed. Specification 391,239 is referred to.

Tool spindle 29, rotatable about axis 38, carries tool 30 for producing the outer circular profile of the cam body 31 which is clamped on turn-table 40 of a workpiece spindle rotatable about axis 39 by motor 42. A first store 96 holds data relating to the shape (law) of the desired camming surface, i.e. the relation between the displacement magnitude of the driven member and the associated angular position of the cam. A second store 72-76 holds data relating to workpiece - dependent parameters for determining the cam surface dimensional characteristics. A co-ordinator associates related data items from each of the first and second stores to generate a succession of angle information signals defining a circular arc corresponding to one on which the rotation axis of a roller follower of given dimensions would move on following the camming surface. A command signal generator, responsive to the angle signals, applies pairs of co-ordinate displacement signals to move the carriage 44 along the circular arc 35 in a plane perpendicular to the support rotational axis. Turntable 40 is movable on carriage 44 in the X-direction by motor 46 and in the Y direction by motor 50, the motors having respective transmitters 47, 50. The cam shape store can hold these shapes in numerical form i.e. in the form of normalized co-ordinate pairs, or in the form of a mathematical law whereby a calculation for each individual cam is carried out during processing. Drive motor speed is provided from digital store 105 via D/A converter 52 and regulator 54 while X-Y axis motion of support 44 is determined by circle interpolator 100.
