In one example a resulting 3#-ol is converted to 3α-formyloxy-18-methyl- 19 - nor - 5α - pregnan - 20 - one and this is then hydrolysed to the corresponding 3α-ol. 17# - Acetoxy - 18 - methyl - 19 - nor - 5#,17α- pregnane - 3,20 - dione and the corresponding 5α - compound are prepared from 17α - ethynyl - 17# - acetoxy - 18 - methyl - #<SP>4</SP>- estren - 3 - one by converting this to 17#- acetoxy - 18 - methyl - 19 - nor - 17α - #<SP>4</SP> - pregnen - 3,20 - dione and catalytically hydrogenating this. 18 - Methyl - 19 - nor - #<SP>4'16</SP>- pregnadiene - 3,20 - dione is prepared from 17- ethynyl - 18 - methyl - #<SP>4'16</SP> - cotradien - 3 - one. The novel steroids have a central-depressive anaesthetic-narcotic action and anticonvulsive activity, and they may be made up into pharmaceutical compositions with suitable carriers.

Title: Headlamp tilting device in a motor vehicle

Filed: 1974-07-24
Abstract: 1509378 Directing vehicle lamps LUCAS ELECTRICAL Ltd 9 July 1975 [24 July 1974] 32636/74 Heading F4R In a system for tilting headlamps 12 in response to changes in attitude of a motor vehicle body 10, a sensor 15, 16 gives a mechanical output in response to such changes which is transmitted by a lever 17 to the pivoted headlamps under the control of a damper 19 which permits linear displacement of a pivot 18 only for relatively slow movements of the sensor 15, 16 so that the headlamps 12 are tilted to a greater extent for relatively sudden changes of attitude, e.g. during acceleration, than for slow changes, e.g. loading of the vehicle. As shown, the sensor comprises an inner cable 15 attached at one end to an unsprung body part 14 and a the other end to the lever 17, and an outer sheath 16 in abutment with a sprung body part 10. Changes in body attitude vary the effective length of the inner cable 15 to move the lever 17. The headlamps are mounted on a pivoted bar 13 connected to the lever 17 by a cable 24 and a sprung double arm arrangement (Fig. 2, not shown). The damper 19 includes an hydraulic cylinder and piston with a return spring (Fig. 3, not shown). High frequency changes in body attitude, e.g. due to uneven road surfaces, do not tilt the bar 13 because it is also controlled by a further damper 29. In another embodiment, the headlamps are controlled independently by two sensor cables and levers (Figs. 4-6, not shown).

Title: Improved apparatus for determining the angular position of an object
IPC: G01C9/22
Filed: 1920-11-19
Abstract: 161,555. Schoute, C. April 7, 1920, [Convention date]. Rudders.-An apparatus intended to give a continuous electrical indication of angular movements consists of two interconnected tubes 1, 2 partially filled with a conducting-liquid such as mercury arranged to be turned about an axis 5 in accordance with the angular movement to be measured. One tube 2 has in it a conductor 6 of comparatively high resistance in the form of a straight wire or spiral arranged in parallel with an ammeter 10 in relation to a battery 8 and a resistance 9 large with respect to that of the wire 6. Two sets of tubes with the wires in the arms of a Wheatstone bridge may be used. The invention may be used to indicate the position of a ship's rudder.

Title: Improvements in or relating to non-reciprocal electromagnetic transmission systems
IPC: H01P1/365
Filed: 1955-11-16
Abstract: 793,164. Non-reciprocal waveguide transmission systems. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Nov. 16, 1955 [Nov. 19, 1954], No. 32787/55. Class 40 (8). A non-reciprocal transmission arrangement comprises a strip of highfrequency ferromagnetic material, e.g. ferrite, arranged in a waveguide at a point where the magnetic vector is circularly polarized, the strip being magnetically polarized in a plane normal to the plane o f rotation of the vector to a degree sufficient to produce ferromagnetic resonance at the working frequency. To improve the impedance-matching of the strip it is provided on one side with a layer of dielectric material the dielectric constant of which is equal to the square root of the dielectric constant of the ferrite material and the thickness of which is equal to of the wavelength in the dielectric. For a rectangular guide 1 propagating in the H01 mode the ferrite strip 2, provided with matching dielectric layer 3, is situated at a point defined by: (p is the propagation constant), where the Hx and Hz components of the high-frequency magnetic field being equal and in quadrature combine to produce a vector of constant magnitude rotating in a sense determined by the direction of propagation. If the sense of rotation is the same as that of the electron-spin precession produced by the polarizing field Ho absorption of the electromagnetic wave results. For the opposite sense of rotation, corresponding to the opposite direction of propagation, absorption is negligible. The invention may be applied to circular guides in which for Ho modes of propagation a circularly polarized field exists at two different radial distances from the axis. A ferrite cylinder having a radius equal to either of these distances is axially arranged in the guide and is circumferentially polarized by means of a D.C. conductor situated along the axis. The matching dielectric layer is arranged inside or outside the ferrite cylinder according to whether the radius of the latter has the greater or less of the two alternative values. The dielectric may be quartz glass.
