Title: Processes for the preparation of 17ª‡-ethynyl-17ª‰-hydroxy derivatives of 13ª‰-?-propyl-18-nor-estradiol
IPC: C07J75/00
Filed: 1961-12-13
Abstract: The invention comprises compounds having the formulae <FORM:1005726/C2/1> wherein R represents H or an acyl radical or alkyl radical and processes for the preparation of a 17a -ethynyl-13b -n-alkyl-18-nor-estradiol by selectively oxidizing 13b -n-alkyl 18-nor-estradiol at the 17-position so as to form the corresponding estrone which after preliminary etherification at the 3-position is then ethynylated by reaction with ethynyl magnesium halide. Selective oxidation may be effected with aluminium isopropylate in the presence of cyclohexanone and etherification may be effected with a -tetrahydropyranyl ether. Specifications 979,891 and 1,005,727 are referred to.

Abstract: 1,154,264. Making pipes; continuous casting. TSENTRALNOE KONSTRUKTORSKOTEKHNOLOGICHESKOE BYURO. 10 Oct., 1967, No. 46306/67. Headings B3A and B3F. A method of making cast iron pipes includes the steps of continuously casting a strip from molten iron which has been inoculated by the addition of ferrocerium; annealing the strip; cooling the strip and cutting it into narrower strips; bending each strip into a pipe blank and welding the edges together to form a pipe and cutting the welded pipe into separate lengths. As described the molten iron is inoculated before it is fed between a pair of cooled rolls (see below) to form a strip which is then wound into a coil. The coils are then placed in a furnace for annealing at a temperature of 950‹ to 900‹ C. for 6 to 7 hours, followed by rapid cooling to 790‹ to 800‹ C. and slow cooling to 630‹ to 650‹ C. The coil is then cooled in an air current to ambient temperature. The coil is then uncoiled and passed through disc shears to be cut into narrower strips. Each strip is then passed through a multistand mill where it is bent into a cylindrical pipe blank. Alternatively, each strip may be wound into a spiral to form the blank. The edges of the blank are then welded by a high frequency loop inductor, the welding flash is removed, the pipe is passed through two gauging stands and is then cut into shorter lengths. Each pipe length is then tested under pressure, dried, dipped into a waterorganic suspension of polyethylene and finally dried at a temperature of 150‹ to 250‹ C. to fuse the polyethylene to the pipe surface. In the continuous casting step the molten iron is fed from a tundish 8, which is supported by an arm 7 on a rotating column 6, through an electrically heated feeding pipe 11 which is provided with a plurality of holes 12. The molten iron is discharged at a temperature of 1250‹ to 1350‹ C. and falls between rollers or moulds 13 which are urged towards each other by an by - draulic cylinder 14 and cooled inside by running water. The strip 15 thus formed passes over a guide 16 and conveyer 17 and is wound into a coil 19.

Abstract: 1,165,779. Controlling vehicles. FORD MOTOR CO. Ltd. 12 Oct., 1967 [3 Nov., 1966], No. 46573/67. Heading B7H. A control system for use with the transmission and gas turbine engine described in Specification 1,160,710, comprises a control lever 72, which may be the selector lever of the automatic transmission or a conventional clutch pedal and which, by its movement from position D to position N causes an interruption of the vehicle drive, and a linkage 68, 66, 80 connecting the lever 72 to a control lever 16 for moving a fuel control nozzle into a position for engine braking. A second linkage actuated by an accelerator pedal 30 includes a bellcrank 34 having a pin-and-slot connection 40, 42 with a link 44 connected to a fuel supply control lever 45 and to a nozzle position control lever 12 through a link 46. The pin 42 slides in the slotted arm of a lever 52 pivoted at 54 and which itself has a pin-and-slot connection 58 with an arm of a bell-crank lever 60 pivoted at 62, the other arm 64 of which is pivoted to the links 66 and 68. When the lever 72 is in the position N in which the drive is interrupted, e.g. the transmission is in neutral or the clutch is disengaged, the links 66 occupy the broken line position causing the bell-crank lever 60 to move the lever 52 to a position whereby the pin 42 is withdrawn from the slot 40 whereby the accelerator pedal 30 becomes inoperative. When the transmission is re-engaged the pin 42 returns into the slot 40 and the link 44 is again operated through the bell-crank 34 by the pedal 30. A cam 86 is integral with lever 45 and co-operates with a link 82, pivoted at 84 and connected to the links 80 and 66 whereby, when the accelerator pedal is depressed and the cam occupies the broken line position-and the links 80, 66, 68 are in the full line position the lever 72 being at drive, movement of the lever 72 from drive to neutral (or disengagement of the clutch) is prevented.

At the same time, the handle shaft 28 drives through a flexible shaft 82 to turn two plates 96, 100 coupled by a rod 98 eccentric to their coincident axes of rotation. Downwardly depending ears 110a, 110b, Fig. 4, on a bracket 106 fast within the upper part 68 of the doll's torso which is pivoted on the lower part 70 of its torso, embrace the eccentrically mounted rod 98.

In the latter, the brush 20 is dipped into paint, &c 150 in receptacles on a table 12b. The doll's arm 64a carrying the paint brush 20 is journalled by a ball-andsocket 78, Fig. 4, together with a shaft 130, in the upper torso 68. A flexible strap 112 (see also Fig. 3) connects a radial pin 128 to a lever 120 engaging a cam surface on the periphery of the plate 100. As the latter turns with the handle 30, the doll's arm 64a and the paint brush 20 are raised away from the paper 18, the upper torso 68 turns on the lower 70, and the arm 64a is then lowered to dip the brush 20 in the paint 150.
