Title: Steroid 3-enamines
IPC: C07J43/00
Filed: 1954-05-11
Abstract: The invention comprises a 3-amino-11-oxygenated-3,5,17(20)-pregnatrien-21-oic acid alkyl ester represented by the following formula <FORM:0779001/IV(b)/1> wherein R1 is an a -hydroxy group, a b -hydroxy group of ketonic oxygen, and wherein R3 is an alkylene group containing less than nine carbon atoms, which together with the nitrogen atom, forms a ring which contains five or six members, and R2 denotes a lower alkyl radical containing one to eight carbon atoms inclusive, and the preparation thereof by reacting the corresponding esters of a 3-keto-11-oxygenated-4, 17(20)-pregnadien-21-oic acid with a cyclic alkylene amine represented by the formula R3NH, e.g. pyrrolidine, piperidine, 2,4-dimethylpiperidine, 3-propylpiperidine, 2-methylpyrrolidine, 3,4-dimethylpyrrolidine, 3-ethylpyrrolidine, 3-isopropylpyrrolidine, and 3,3-dimethylpyrrolidine.  The reaction may be effected in the presence of an acid catalyst, e.g. p-toluenesulphonic acid, benzene sulphonic acid, sulphoacetic acid, anhydrous hydrogen chloride, and concentrated sulphuric acid.  For maximum yield the water of reaction should be removed. Examples disclose the production of 3-pyrrolidyl-11-keto - 3,5,17(20) - pregnatrien - 21 - oic acid methyl ester, 3 - piperidyl - 11 - keto - 3,5, 17(20) - pregnatrien - 21 - oic acid methyl ester, 3 - piperidyl - 11a  - hydroxy - 3,5,17(20) - pregnatrien-21-oic acid ethyl ester and 3-piperidyl-11b  - hydroxy - 3,5,17(20) - pregnatrien - 21 - oic acid methyl ester.

Filed: 1972-03-28
Abstract: 1366198 Cathode-ray tube deflection circuits SPERRY RAND CORP 28 March 1972 [12 April 1971] 14490/72 Heading H3T An electron beam deflection circuit operable alternatively as a linear amplifier or in resonant return sweep mode, has a single ended push-pull output stage having one side connected to the deflection coil via a diode and in which both sides may be rendered non-conductive to allow resonant return. The class B transistor amplifier shown has negative feedback from a currentsensing resistor Rs so that the horizontal deflection current accurately follows the input at 12 and allowing production of a linear ramp and character formation during the vertical retrace period. To effect resonant return a pulse at 13 causes both lower output transistors Q10 and Q11 to be cut off and as the upper output transistors Q8 and Q9 are also cut off during the second half of the scan and during retrace, the deflection circuit rings, the oscillation being terminated after half-cycle by the end of the pulse at 13 and by the conduction of Q8 and Q9 at the start of the next trace. A diode D4 protects Q8 and Q9 from the high voltage of resonant retrace and C2 provides feed-forward to improve high frequency performance.

Sharp angular bends are formed in the contact end portions 10 of a plurality of parallel flexible wires 11, mounted near their opposite ends in an insulating block 13 of a switch part, by punch and die apparatus in which the insulating block is supported on the die with the wires extending perpendicular to the direction of reciprocation of the punch, the wires are then flexed against a curved surface on the die by means associated with the punch and, while thus flexed, the ends are given permanent sharp angular bends by shaping between opposed surfaces on the punch and die, the punch being then removed to allow the flexed parts of the wires to straighten. An insulating block 13 is advanced along a guide, by a pawl 62 on a reciprocated feed bar 61, to a groove 27 in a supporting member 26, raised above a die 20, and is positioned thereon by spring-urged pins 28 engaging holes 15 in the block 13. A punch 23 is then moved down so that spring- urged pads 30, 31 engage the wires 11 adjacent the clock 13 and depress the member 26, against springs 65, into the die 20. A rocker plate 50, pivoted at its ends to spring-urged rods 51 (not shown) and 52 in the punch 23, then flexes the wires 11 in grooves 56 on a curved surface 35 of the die 20. Continued downward movement of the punch 23 causes a punch element 42 to form a permanent right-angle bend in the ends of the wires, in co-operation with surfaces 37, 38 of the die. The punch 23 is then advanced a predetermined distance relative to the element 42 to cause a shaping surface 46 on the punch to form another permanent right-angle bend. The punch is then raised and the wires allowed to unflex and the switch part is removed by the pawl 62. Specification 731,486, [Group XXXVII], is referred to.
