Title: Improvements in or relating to new analgesically active substituted alpha, alpha-diphenyl--y-amino-butyramides and the manufacture thereof
IPC: C07D295/145
Filed: 1956-10-23
Abstract: The invention comprises compounds of the general formula <FORM:0822055/IV (a)/1> (wherein either (1) R represents a mono- or dialkylamino or heterocyclic amino group, A a dialkylamino or heterocyclic amino group, R1 a methyl group and R11 hydrogen, or (2) R represents a mono- or di-alkylamino or heterocyclic amino group, A a morpholino group, R1 hydrogen and R11 hydrogen or a methyl group, or (3) R represents a monoethylamino or pyrrolidino group, A a piperidino group and R1 and R11 both hydrogen), and the preparation thereof by (a) (when R is dialkylamino or heterocyclic amino) reacting an aminoalkyl halide Hal-CHR1-CHR11-A with an alkali metal derivative of a diphenylacetamide compound, of the formula (C6H5)2-CMe-CO-R (Me=alkali metal), or (b) (when R11=H) reacting an acid halide A-CH2-CHR1-C(C6H5)2-CO-Hal with a mono- or di-alkylamine or a heterocyclic amine (preferably two molecular proportions thereof) at a temperature below the cyclization temperature of the acid halide.  When R1 and R11 are not both hydrogen, process (a) yields a mixture of isomers, which may be separated by making use of the difference in solubility of the bases or their salts in certain solvents, e.g. of the hydrochlorides in acetone or the bases in ether/petroleum ether.  Process (b) may be combined with the preparation of the acid halide by treating the corresponding amino acid, or a mineral acid salt thereof, with excess of a halogenating agent (e.g. thionyl chloride or phosphorus trichloride).  Examples and a table describe compounds containing various combinations (within the limits of the definitions above) of the following meanings of R and A; R=methylamino, ethylamino, isopropylamino, n-butylamino, dimethylamino, diethylamino, pyrrolidino, piperidino, 2-methyl-, 2 : 6-dimethyl- and 2-methyl-5-ethyl-piperidino, morpholino; A=morpholino, piperidino, dimethylamino, pyrrolidino. The hydrochlorides of some of the products are described. Specification 772,921 is referred to.ALSO:Analgesic compositions contain, in admixture with a physiologically inactive diluent material, one or more compounds of the general formula <FORM:0822055/VI/1> wherein either (1) R represents a mono- or dialkylamino or heterocyclic amino group, A a dialkylamino or heterocyclic amino group, R1 a methyl group and R11 hydrogen, or (2) R represents a mono- or di-alkylamino or heterocyclic amino group, A a morpholino group, R1 hydrogen and R11 hydrogen or a methyl group, or (3) R represents a monoethylamino or pyrrolidino group, A a piperidino group and R1 and R11 both hydrogen.  An example describes tablets and a powder containing 1-(4-N-morpholino-4-methyl-2 : 2-diphenylbutyryl)-pyrrolidine.

Patent GB-787129-A (GB)
Title: Improvements in and relating to winding machines
IPC: B65H54/28
Filed: 1954-11-08
Abstract: 787,129. Winding yarn. UNIVERSAL WINDING CO. Nov. 8, 1954 [Jan. 18,1954], No. 32314/54. Class 120(2) A method of winding a package of yarn comprises the steps of rotating a core to wind a yarn thereon, reciprocating a strand of yarn along a predetermined path longitudinally of the core to lay the yarn thereon in spaced helices to form the package, separating the axis of the core and, the path, of the reciprocating strand of yarn and modifying the rate of separation between them to decrease generally the said rate throughout the winding cycle. As shown, in a machine for effecting the method, depression of the starting handle 80 releases a brake 76 from a pulley 45 and raises a pulley 54 to tighten a driven belt 43 to drive the shaft 38, which, through a belt 46 rotates the spindle 34, and through belts 52, 32, drives the shaft 26 to reciprocate a yarn. guide 28 through the intermediary of a barrel cam on the shaft 26. Rotation of the spindle 34 operates through a speedreduction gearing 178, Fig. 7, to rotate the pinion 141 to move the housing 36 about the shaft 38, the housing 36 carrying the spindle 34 and yarn package on its holder 18. The segment 140, meshing with the pinion 141 is pivotally carried by the shaft 38 and connected with the housing 36 by a link 197, the other end of which is connected to a cam 195. pivoted at 196 to the segment 140. The cam 195 bears upon a roller 199 carried by a shaft on the machine frame. The cam 195 is replaceable so that the relative motion between the segment 140 and housing 36 may be modified in any desired manner to give the required rate of separation of winding spindle 34 and traverse guide 28. The main belt 43, through a speed reduction device 205 (not shown), shaft 204 and belt 203. drives the shaft 200 of the roller 199, which is eccentrically-mounted, so that the spacing of the yarn traverse guide 28 from the package is slightly lengthened and shortened so that the end portions of each traverse are differently spaced from the ends of the package so to avoid the formation of "knuckles". If a yarn breaks, a lever 110 carrying a thread-engaging wire 124 swings to bring an abutment 128 into' the path of a power-driven member to disengage a latch 104 and raise the lever 80 to separate the driving belt 43 from the pulley 45. In order that the housing 36 may be brought back towards the guide 28 for a new wind, the reduction gearing between the spindle 34 and pinion 141 is provided with a sliding bevel gear 182 which may be kept in the disengaged position by a latch 211. The winding core 18 is locked on the spindle 34 by the movement of a hand lever 207 a finger 208 moved thereby being operatively connected to the bevel gear 182 of the speed-reduction gearing.

Title: Improvements in and relating to electric power converting apparatus
IPC: H02M7/15
Filed: 1931-11-23
Abstract: 390,562. Converting ; frequency and phase changing. BRITISH THOMSONHOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Livingston, O. W. ; 841, Main Avenue, Schenectady, New York, U.S.A.) Nov. 23,1931, No. 32426. Convention date, Nov. 21, 1930. [Class 38 (ii).] Relates to power-converting apparatus in which a load circuit 11 is supplied from an A.C. circuit 10 through valves 13, 14 and 15, 16 connected to form oppositely conductive full wave rectifiers and consists in a grid circuit by means of which the grid potentials of one pair of the valves are maintained substantially 180‹ out of phase with their anode potentials while the phase of the grid potentials of the other pair is being varied. Transformers 21, 24 supplying grid potentials to the valves 13, 14 and 15, 16 respectively are connected to the centre-tapped secondary of a transformer 30, the common connection including the secondary winding of an induction regulator 27. Referring to the vector diagram in Fig. 2, OA, OA<1> represent the potentials applied to the anodes of valves 15, 13, OB, OB<1> the potentials induced in the windings 29, 28 and BD, B<1>C the potential in the secondary_ of the induction regulator 27. The potentials across the primaries of the grid transformers 24, 21 will therefore be OD, OC respectively. By varying the induction regulator from zero to a maximum the length of BD, B<1>C is varied and considerable variation of the phase angle b takes place, while the phase angle a remains approximately constant. If the direction of the vectors B<1>C, BD is reversed by turning the induction regulator through 180‹, the phase angle a will remain approximately constant and the phase angle b will vary upon adjustment of the regulator. So that by moving the induction regulator from zero to a maximum in either direction, one pair of valves is held non-conducting while the output of the other pair is regulated. By driving the induction regulator by means, e.g. a motor 33, an A.C. output can be obtained, the frequency of which is governed by the speed of the motor.

Abstract: 245,448. Levi, I., (trading as Fabbrica Italiana di Penne a Serbatoio Aurora). Jan. 5, 1925, [Convention date]. Self-filling nib-retracting rcservoir pens. - A reservoir pen is provided with a body 1 carrying the nib 2 and a collapsable sac 3, and arranged to reciprocate in the barrel 7 so as to project the nib for writing-purposes or to uncover the sac-operating member for refilling. A pin 11 secured to the body 1 slides in a slot 10 in the barrel, a split ring 12 being so disposed as to arrest the movement of the pin. A spring 15 is secured to the barrel 7, and is provided with a lug 14 engaging a cover 9 acted on by a spring tending to hold it in open position. Movement of the body 1 causes the release of the cover 9 by the action of the front end of the body on a projection 16 on the spring. The cover 9, which is bent so as to lie close to the body 1 when the latter is projected, may also be closed automatically as a result of the movement of the bodv 1. The ring 12 normally restricts the movement of the pin 11 so that the nib is only projected to writing-position, but the ring is movable to permit the passage of the pin and allow the projection of the body to such a point that a stud 5, which extends through an opening in the body and which is formed on a rigid strip 4 in contact with the sac 3, is exposed at the front end of the barrel.
