Title: New-6-alkyl-steroids
IPC: C07J75/00
Filed: 1963-02-15
Abstract: The invention comprises steroids of the formula <FORM:0980245/C2/1> (wherein R1 is C1-6 alkyl; R2 is H(OH), H(O-acyl) or O; and R3 is H, OH or O-acyl) and their preparation by reductive removal of the 3-keto group from D 4-3-keto-6a -alkyl-19-nor-pregnenes containing a 20-keto, -hydroxy or -acyloxy group, followed, when required, by oxidation of the 20-hydroxy group to a 20-keto group and conversion of the resulting D 4-6a -alkyl - 20 - keto - 19 - nor - pregnene compound to the corresponding 17a -hydroxy compound. The 3-keto group may be split off by conversion to a 3-thioketal group followed by reductive splitting of this, for example by reaction with an alkali metal in liquid ammonia; or by reduction to the 3-hydroxy compound, esterification or etherification of this, and reductive splitting of the 3-ester or -ether group.  The 20-hydroxy group already present or formed in these processes may then be oxidized and a 17a -hydroxy group introduced, for example by conversion into a 20-enolacylate, oxidation to a 17,20-oxido compound, and hydrolysis.  Prior to oxidation and enolacylation the D 4-double bond is preferably protected by addition of halogen, the 4,5-dihalogen steroid formed being subsequently dehalogenated.  17a -hydroxy-products and 20-hydroxy products may be esterified with carboxylic acids containing 1 to 30 carbon atoms.  20-Ketones may also be reduced to 20-hydroxy compounds. Examples are given.  The steroids of the invention are stated to exercise a progestative, anti-estrogenic and ovulation-inhibiting effect, and may be made up into pharmaceutical compositions with suitable carriers.  Solutions, suspensions, tablets, pills and capsules are referred to.  Specification 979,037 is referred to.

Abstract: 1493515 Testing electromagnetic actuators SIE SOC ITALIANA ELETTRONICA SpA 14 Feb 1975 [20 Feb 1974] 6306/75 Heading G1U The electromagnetic functioning (i.e. coil inductance) of an electromagnetic actuator is tested by applying thereto the type of signal needed to actuate the actuator, but for a time shorter than that required, and monitoring the current generated by self-induction at deenergization of the coil. A normally de-energized relay coil E with a normally open contact X is tested by closing a contact Y for a time T t  which is less than the reaction time of the relay, which therefore does not operate Transistor Q 1  turns on, energizing the coil E and the current i e  rises to a maximum i E  determined by circuit parameters. On the re-opening of Y, the energy stored in the coil E equal to ¢ Li E <SP>2</SP> is dissipated through transistor Q 2  providing an output pulse across R3 at output J which indicates correct operation of the coil. If the coil is normally energized (i.e. X normally closed), the arrangement is tested by opening contact Z for the time Tt.

Title: Calibration of radar equipments
IPC: G01S7/40
Filed: 1949-03-10
Abstract: 658,686. Radiolocation. BRITISH THOMSON-HOUSTON CO., Ltd., and MATON, R. W. March 10, 1949, No. 6585. [Class 40 (vii)] An arrangement for calibrating a radar set employing a cathode-ray-tube display arrangement, comprises means for applying in alternation to the display unit fixed-range markerpulse signals and variable-range pulse signals whereby the variable-range signals may be calibrated with reference to the fixed-range signals. A saw-tooth waveform A, corresponding to the sweep waveform for the cathode-ray display, and a large-amplitude oscillatory waveform B, which is derived from a circuit which is shock-excited at the instant of pulse transmission, are applied alternately by means of a continuously-operated relay R to the grid of a valve V1 which together with a valve V2 forms a cathode-coupled flip-flop arrangement. At the beginning of each sweep of the cathode-ray tube, valve V1 is non-conducting. However, as the potential applied to its grid exceeds a predetermined value, V1 conducts while V2 ceases conducting, thus shock-exciting inductance 4. By virtue of the rectifier 5 connected across the inductance, the oscillation therein is limited to a pulse comprising a single half-cycle of oscillation. This pulse is applied to amplifier 12 and thence to the cathode-ray tube 13. The potential of the grid of V1 at which the change-over occurs may be varied by means of the potentiometer 14 which varies the bias applied to the grid of V2. The timing of the variable-range pulse produced when waveform A is applied to V1 is thus controlled by the potentiometer 14; the timing of the fixed-range pulses produced when waveform B is applied to V1 is, however, sensibly independent of the potentiometer due to the large amplitude of the signal. Fig. 3 illustrates a portion of a P.P.I. display wherein fixed-range marker indications 18 and 19 occur in alternation with variablerange indications 21. By aligning the variablerange indications with the fixed-range indications, the scale 17 associated with the potentiometer 14 may be calibrated. To prevent spurious indications from being produced when the relay R changes over, an additional relay 22 synchronized therewith is provided. When the contacts of relay 22 are open, the bias potential applied to amplifier 12 rises to zero, thus preventing the normal operation of the amplifier and preventing any signals applied thereto from affecting the display.

Title: Improvements in or relating to control means for driving mechanism
IPC: F16H15/02
Filed: 1956-03-02
Abstract: 792,073. Kinematograph apparatus. KODAK, Ltd. March 2, 1956 [March 3, 1955], No. 6627/56. Class 97(1) [Also in Group XXIV] An interlock is provided between the control of a reverse gear, for driving a kinematograph projector, and the switch 31 of its driving motor 32, whereby the motor switch can only be operated in neutral and the gear can only be shifted with the motor switch on. A link 47 also automatically neutralizes the gear when a reel arm 13 is swung back into the machine casing after use. The reverse gear comprises a pair of friction discs 17, 18, rotating with an output shaft 16 and movable axially together as a unit to bring either disc into frictional engagement with a coned driving roller 22 on the shaft of the motor 32. The friction discs 17, 18, are shifted by manually turning a shaft 30 carrying a cam 29 which shifts the discs through a lever 25. The reversing shaft 30 also carries a disc 42 having a notch 35 which, in the central neutral position of the cam 29, registers with a toe on the end of a lever 37 operated by the control lever 33 of the motor switch 31, so that, with the switch lever in the down, off, position, Fig. 3, the lever toe enters the notch 35 and prevents movement of the reverse cam 29 from neutral, whilst switching the motor on, possible only in neutral, retracts the lever 37 and permits cam movement to forward or reverse. When, after use, the reel arm 13 is folded inside the projector casing, this movement thrusts the link 47 to the right (Fig. 2) so that, if the reverse cam 29 is in either operative setting, a ledge 52 on the link strikes one or other end of an arcuate lug 51 on the back of the cam, turning it back to neutral.

Abstract: 1,055,042. Coin sorting and testing. NATIONAL REJECTORS Ltd. Feb. 17, 1965 [March 2, 1964], No. 6821/65. Headings G4V and G4X. A coin tester is arranged to accept coins of a given resistivity, and hard coins of greater resistivity, but to reject coins of less resistivity and soft coins of greater resistivity. In particular, it will accept silver and cupronickel, but reject copper, zinc, brass or lead. The apparatus described sorts coins of the diameters of dimes, nickels, and quarters, an inserted dime dropping through two cradles to a conventional dime tester, and an inserted nickel being arrested by the second cradle, subjected to a washer test, and tilted on to a runway where it is subjected to retardation by a magnet, and whence it passes to a rebound tester substantially as in Specification 740,794. A quarter sized coin is arrested by the first cradle, subjected to a similar washer test, and tilted on to runway 174, whence it passes through the field of magnet 118. A silver coin will be slowed to a predetermined extent, and follow path 200, striking a separator 95 on lever 94 pivoted at 96, so that the lever tilts as shown in broken lines, the coin passing to the right of the separator to acceptance path 192. A cupronickel coin will be little slowed, and will hit a rebound surface 85, and being hard, will rebound to hit a second rebound surface, which may be the hardened end 176 of the runway or a separate member. The coin rebounds again to the right of the separator and is accepted. A zinc or brass coin will be slowed to a degree between cupronickel and silver, and will hit the lower part of surface 85 a glancing blow, being deflected to the left of separator 95 to a reject path 194. A copper coin will be more slowed than silver, and will drop to the left of separator 95. A lead coin will be little slowed, but its rebound from surface 85 will be too small for it to engage surface 176, and it will fall between that surface and separator 95 to path 194.
