Abstract: 516,443. Sexhormones. SOC. OF CHEMICAL INDUSTRY IN BASLE. June 27, 1938, Nos. 18990 and 18991. Convention dates, June 25, 1937, and June 4, 1938. Sample furnished. [Class 2 (iii)] Saturated or unsaturated hydroxyketones of the cyclopentanohydrophenanthrene series are prepared by reducing free keto groups in saturated or unsaturated polyketo-cyclopentanohydrophenanthrene compounds, in which some of the keto groups had been converted into substituted enol groups. The products may be acylated or saponified. One part of androstenedione-3-enolbenzoate is mixed with fourteen parts of dry isopropyl alcohol and three parts of al isopropylate and boiled under reflux. The greater part of the isopropyl alcohol is distilled off and the residue poured into water and extracted with ether. The ethereal extract is washed with dilute NaOH and water, dried over Na2SO4 and evaporated. The residue is taken up in a little alcohol to which a little hot water is added and by cooling testosterone-3- enolbenzoate is crystallized. This compound is boiled with fifty parts of methanol, one part of anhydrous K2CO3 and ten parts of water to give pure testosterone. Reduction may be effected generally by chemical, catalytic or by biological means (e.g., yeast). In example 2, androstenedione-3-enolpropionate is reduced by fermentation and the product saponified to give testosterone.. In example 3, testosterone-3-enolbenzoate as produced in example 1 is dissolved in dry pyridine and treated with benzoyl chloride to give testosterone-3-enolbenzoate-17-benzoate. In example 4, progesterone-3-enolbenzoate is reduced by heating with al isobutylate and saponified as in example 1 to give pregnenol-(20)-one-(3).

Title: Gyroscopic theodolite
IPC: G01C19/38
Filed: 1967-04-26
Abstract: 1,132,948. Gyroscopic apparatus; theodolites. FILOTECNICA SALMOIRAGHI S.p.A. April 26, 1967 [Nov. 2, 1966], No.19203/67. Headings G1C and G1F. A gyroscopic theodolite comprises a casing, a theodolite 1 mounted on the casing, a gyroscopic pendulum 4 suspended by a pair of crossed strap resilient members 8 having a single degree of freedom, an indexing reticle 13 fixed to the casing and an optical system for projecting an image of the reticle 13 on a reference reticle 25. The gyroscopic pendulum comprises a gyroscope having a vertical axis of rotation and the weight of the pendulum is lightened by filling its inner portion with oil. The optical system consists of a lamp 11, a double prism 14, prisms 15-17, a lens 21, a mirror 22 and an inspection microscope 23-26. The prisms 15, 17 are fixed to the pendulum 4 and the instrument is initially levelled by a level 32 and screws 29 so that the image of the reticle 13 lies within the image of the reticle 25. On rotation of the gyroscope rotor, the deviation of the pendulum causes a deviation of the prisms 15, 17 and the instrument is again adjusted to centre the reticles by rotating the gyroscope assembly 2 so that the axis of suspension of the pendulum lies in the meridian plane. The assembly 2 is then locked in position by a screw 28 and the axis of a telescope 30 is in the meridian plane when the reading on a horizontal circle 34 is either zero or 180 degrees. On subsequent rotation of the theodolite vernier and pointing the telescope in a given direction, the corresponding reading on the circle 34 gives the geographic azimuth of the direction. Modifications are described which include an additional static pendulum or an additional gyroscopic pendulum for the purposes of eliminating errors due to the yielding of the stand. The additional gyroscopic pendulum also increases the sensitivity of the instrument.

Title: Improvements in or relating to arrangements for supplying direct current machines through converters employing grid-controlled electric discharge devices
IPC: H02M7/00
Filed: 1937-07-12
Abstract: 483,897. Control of D.C. motors ; converting. SIEMENS - SCHUCKERTWERKE AKT.-GES. July 12, 1937, No. 19333. Convention date, July 11, 1936. [Class 38 (iii)] [Also in Group XXXV] Varying E.M.F.; regenerative braking.- A converter employing grid-controlled electric discharge devices, through which a motor 1 is supplied from a source 4, is changed over from rectifier to inverter operation and vice versa under control of means 14 only when the grid regulator is moving, during motoring, in a direction to reduce the converter voltage, or during regenerative braking, in a direction to increase the converter voltage, and at the same time the motor current falls to zero or a pre, determined minimum valve. A grid controller 6 has regulators 7, 16, for motoring and regenerative operation respectively, which regulators are operated by a servo-motor 9 controlled by a coil 10 connected in the diagonal of a bridge circuit formed by resistances 11, 12, the servo-motor operating on the resistance 12, and a controlling lever operating on the resistance 11, so that the servo-motor follows movements of the lever 5. The servo-motor also operates a field controller 8 for the motor during a stage subsequent to the stage during which the motor armature circuit is controlled by the converter. Connected in parallel with the controlling coil 10 of the servo-motor 9 is the coil 17 of a polarized relay 17 which contacts at 19 or 20 depending on the direction in which the control lever is moving. The change from regenerative to motoring connections and vice versa involves a reversal of the armature connections effected by a switch 13, a control of the grid controller 6, and a change-over of the grid regulators 7, 16, under the control of a switch 15. The control of the grid controller 6 and the operating circuits of the switches 13, 15, is effected by a controller 14 which is operated in accordance with the operation of the polarized relay 17 provided the contacts of a relay 18 energized from the motor circuit, are closed. These contacts close when the motor current falls to zero or a predetermined minimum value. Locking means are provided which ensure that the operation of the converter is changed over only to a condition opposite to the existing condition. A relay 21 energized from the circuit completed through contacts 20 of the relay 17, and a time relay 22 ensure that after a time interval following completion of a braking operation, the system is restored to its motoring condition. A relay 23 operates to stop movement of the servo-motor while a changeover of the system is taking place. The speed of operation of the servo-motor may be controlled in accordance with the main current, and the converter is controlled during a change-over to stop the flow of current in the motor circuit.

Filed: 1962-05-22
Abstract: 1,012,729. Colour television tubes. RAULAND CORPORATION. May 22, 1962 [May 22, 1961], No. 19626/62. Heading H1D. A colour-reproducing cathode-ray tube includes an image screen, Figs. 4a, 4b, 4c, which comprises a plurality of sets of phosphor elements, the elements of ,each set, R, B, G, fluorescing in a distinct colour, the sets being interspersed with one another so as to form groups each of which includes one element from each set, in which the lengths of elements constituting some of the groups are elongated in directions radial with respect to the centre of the screen in a predetermined pattern so as to avoid azimuthal distortion. In a three-colour system employing three electron guns disposed at the vertices of an equilateral triangle, the elements in each group being arranged in triads, azimuth error is introduced, viz. the distortion of both the phosphor and the beam triads, more pronounced at the outer periphery of the scan raster and more noticeable in tubes having large deflection angles of 90 degrees or more. The error is stated to be a maximum at three positions, L, and to decrease to zero towards the centre of the screen and to the positions M, and is overcome by progressively lengthening the phosphor elements in a radial sense in groups verging towards points L. An azimuth corrected aperture mask is used with the screen, and contains holes arranged in a hexagonal array having a corresponding shape and distribution as the phosphor elements. In the method of constructing the screen, an azimuth corrected apertured mask is constructed and used in any of the well-known photographic processes for laying down a triad type multicolour screen. The mask is constructed by using a scalloped metal plate, as a pattern for a glass or other photoplate of the same configuration. A photographic emulsion is deposited upon the scalloped surface and illuminated from a point source of light through a mask provided with apertures so disposed and shaped so as to correct for triad shape error as described in Specification 849,554. The developed plate is then itself used as a mask to obtain the final azimuth corrected apertured mask.
